Although the Sikong Mansion has no intention of launching another large-scale battle for the time being, it does not mean that all fronts will remain silent.
During the more than ten years of Chihu's southern invasion, the rebel armies in Hedong, Heluo, Hebei and other places were complex in composition, suffered repeated attacks from the Qing Dynasty, and were constantly being annihilated, or could not bear the pressure and temptation and surrendered to the Chihu people, but they continued to rise and fall.
The resistance movement has never ceased.
In his early years, Xu Huai insisted on sending people deep into the enemy's war zone in the name of camp to contact the resisting rebels and provide support within his ability.
However, after Emperor Shaolong ascended the throne, although he agreed to merge Nanyang, Xiangyang, Jingbei and other counties into Chushan and establish the Jingxiang system to set up a pacification department, in order to restrict Jingxiang, the Privy Council began to directly take over the roads to contact the enemy-occupied areas.
Resistance to the rebels.
However, the Privy Council Office under the chairmanship of Wang Boqian was extremely limited in its ability to support the rebels in the enemy's war zone. However, it could not wait for the rebels to play a role in containing the Red Husbands. It conferred a large number of empty-headed generals and then ignored the weak strength of the rebels.
Due to the reality of supply difficulties, the rebels were ordered to launch a large-scale uprising and attack various pass cities and towns in enemy-occupied areas, causing great damage to the resisting rebel armies everywhere.
After the escape from Beijing incident, the Sikong Prefecture took charge of the military affairs and put relevant work back under the jurisdiction of the Military Intelligence Staff Department. However, the damage that had been suffered was irreparable and many tasks had to be started from scratch.
Fortunately, the successive great victories also once again boosted the morale of the rebels and the masses in the enemy-occupied areas.
The entire Hehuai War Zone is now divided into the jurisdiction of four major camps: Heluo, Jingxi, Jingnan and Xuzhou. The work of liaising and supporting the resistance of the rebels is also specifically assigned to the military intelligence staff committees of each camp.
The Heluo camp mainly contacted the rebels east of the Yaoshan Mountain and the Zhongtiao Mountains. The Jingxi camp sent people deep into Wangwu Mountain, Taiyue Mountain, and Luliang Mountain to contact the rebels. The Xuzhou camp mainly contacted the rebels in the Taiyi Mountain area.
The Taiyi Mountains include Taishan, Yishan, Mengshan, Culaishan and other mountains, which stretch continuously in the central area of Qilu.
Although Prince Pingyanzong still controls Jeju, Yizhou and other places south of the Taiyi Mountains, with the defeat of several major battles, the control over the depth of the Taiyi Mountains has been increasingly weakened.
Also due to the defeat of several major battles, the Prince of Pingyanzong further strengthened the exploitation and oppression of Qilu land, and the unbearable popular resistance activities became active again.
Zhang Xiongshan went to Xuzhou as a military staff officer to establish the Military Intelligence Staff Council. The accompanying personnel were mainly responsible for the preparations for the establishment of military intelligence command schools at all levels.
However, the liaison with the Taiyi Rebel Army did not mean to bypass the Longwu Army and start a new one. The Sikong Mansion also clearly requested that a group of scouts and sentries be selected from Han Shiliang's old department to enrich the team of the Military Intelligence Staff Council. With the dual efforts of Han Shiliang and Zhang Xiongshan
Relevant work will be carried out under the leadership; the rebels who are willing to accept the incorporation will also be under the jurisdiction of Xuzhou Xingying.
Although the Xuhai area and the Taiyi Mountain area are separated by Jeju and Yizhou occupied by the Chihu people, Prince Pingyanzong was worried about the safety of the flanks and did not dare to deploy the main force on the southern front.
Generally speaking, Prince Ping Yanzong's palace is in Jeju, and Yizhou mainly defends key cities, deploying more than 40,000 soldiers and horses. Compared with the 90,000 war garrison under the jurisdiction of the Xuzhou camp, it is already at a huge disadvantage.
At this time, not to mention completely blocking the area south of the Taiyi Mountains, the enemy army could not even prevent the small group of elite troops from the Xuzhou camp from infiltrating.
Therefore, it is not difficult to establish contact with the rebels who still insist on resisting in the Taiyi Mountains. What is difficult is the follow-up work.
The former scouts of the Longwu Army and sentry officers at all levels used to focus on reconnaissance and spying on the enemy's movements. In liaising with the rebels, they mainly focused on granting officials and rewards to lure them for profit. However, they were not responsible for lurking behind enemy lines and mobilizing the masses.
As well as the specific support and reinforcements for the daily activities of the rebels, they are all in the dark.
The military officials selected to join the Military Intelligence Staff Academy can be said to be the first batch of students of the Xuzhou Intermediate Military Command School. After a month of emergency training, Chen Man, Tang Yuan, Yu Mo and others personally led the team and went deep into Taiyi.
In the mountainous area, we stationed in several rebel camps that had restored contact in the early stage, participated in the daily production and operations of the rebels, and gained an in-depth understanding of the current situation faced by the rebels, and provided practical suggestions and help according to current conditions.
Chen Man was originally the guard general of the Zhuxian Town Army Stronghold. He defected to Chushan during the Battle of Ruying and has been serving in the Military Intelligence Department since then. Tang Yuan and others secretly accepted the instigation of the Military Intelligence Department after the Dongjing Allied Forces accepted the recruitment and have been lurking.
Being around Sun Yanzhou, Hu Dangzhou and others, they have been under the guidance and leadership of the Military Intelligence Department for many years. They can all be said to be the old men of the Military Intelligence Department.
After the victory in Yingzhou, in addition to Yang Ji, Han Yunkun and other generals who led the rebels to form the third town of the Xiaosheng Army, most of the latent personnel who had returned to the German army such as Tang Yuan and Yu Mo were incorporated into the Military Intelligence Department to strengthen the work of the Military Intelligence Staff Department.
Ten years after entering Shaolong, after conditions initially matured, Xuzhou Xingying further arranged for these military officials to lead small groups of elites deep into the Taiyi Mountains, and cooperated with the local rebels and the masses to launch guerrilla attacks in the enemy-occupied areas north of Jiyi.
The raiding operation further weakened the Chihu people's control over the central Qilu area, which was also a key pavement for the future recovery of the entire Qilu land.
In comparison, the penetration and liaison work of the Heluo and Jingxi camps in enemy-occupied areas such as Xiaohua, Zhongtiao Mountain, Wangwu Mountain, and Taiyue Mountain were smoother and more thorough.
Ten years before entering Shaolong, the Chihu people and surrendered to the Han army seemed to still have firm control over key pass cities such as Tongguan, Pinglu, Yuanqu, Qinyang, and Gongcheng.
However, the Heluo camp and the Jingxi camp focused on contacting the rebel teams in Xiaohua, Zhongtiao, Wangwu, and the mountains at the southern foot of the Taihang Mountains, sending a large number of personnel to strengthen and develop the rebel teams, and strengthen the raids on the hinterland of enemy-occupied areas.
Overcoming all difficulties, he carried batches of soldiers, armor, weapons and scarce supplies into the mountains on his shoulders and backs. He also sent a large number of craftsmen to strengthen the construction of the rebel army's camps in the mountains and its own production capacity.
Ten years after entering Shaolong, the strengthened rebel teams and mountain camps had isolated Tongguan and several gateway cities occupied by the enemy on the north bank of the Yellow River to a certain extent.
At the same time, the reclamation work along the banks of Heluo, Yingshui, Caihe, Weishui, and Surabaya has been in full swing. On the one hand, it is to restore agricultural production in these areas, and to restore Yingshui, Caihe, Weishui, and Surabaya.
Navigation and city fort construction, on the one hand, will reorganize up to 2.6 million people, mainly in the form of garrison troops.
For a long time, the Sikong Mansion (Exerting Camp, Zhizhishisi) was able to implement the New Deal more thoroughly in Rucai, Nanyang, Jingbei and other places, mainly because the traditional social structure dominated by the gentry clans in Rucai and other places was destroyed by the war.
Including the Jingbei area, the Dongjing Allied Forces were combed through the caves, and Tongbai Mountain was the first to be cleaned up by bandits.
Although Nanyang and Xiangyang did not directly experience war, in addition to being unable to escape the crisis of losing their lives for more than ten years, Xu Huai commanded tens of thousands of elite troops stationed on one side, which was also the key reason why the local resistance forces could not form to resist the New Deal.
The gentry clans fled on a large scale from Nanyang, Xiangyang and other places, and once formed a force opposing the New Deal in Jianye and other places. However, after the escape from Beijing, they were ruthlessly purged by Xu Huai. In addition to Jin Zhuangchen and his son, a group of
In addition to the death penalty, thousands of Nanyang gentry and their children who were involved with the Jin family were exiled to the Tubo Highlands.
Subsequently, the Sikong Mansion in Shouhao, Guangzhou and other places was completely run by township officials and implemented the New Deal. This was mainly due to the fact that these areas were more completely devastated by the war.
However, in Jiangdong, Zhejiang, Jingbei, Jiangxi and other places, Xu Huai had to adopt more moderate, even compromising means, only clearing out the privately owned fields of the gentry clan and promoting limited tenancy restrictions.
The interest movement was used to alleviate conflicts at the bottom, increase local tax sources, and reserve some official land, but it did not directly touch the lowest level of governance structure.
In addition to the widespread establishment of township bureaus and the lack of enough qualified township officials to fill them, the more important reason is that these places have not experienced the ravages of war, and the traditional social governance structure is relatively stable.
This stability is not only due to the extremely stubborn and powerful power of the gentry clan in the grassroots society and its deep roots. Not only is the traditional concept of clan patriarchy deeply rooted in people's hearts for thousands of years, but more importantly, it is the people at the bottom, especially the relatively wealthy Jianghuai
As long as they are willing to work hard and work day and night, the tenant farmers in Jinghu can still barely survive. They are accustomed to dependence on the clan and have no desire to overthrow or directly participate in grassroots social governance.
Not to mention that this desire is very strong, it is even difficult to sprout.
The local ruffians are very willing to participate in grassroots social governance, but it is impossible for the Sikong government to really use a large number of local ruffians to govern the vast and complex rural society.
At present, the Sikong Mansion is strengthening the training of military officials in various prefectures. The early goal is to truly master the military deployment departments of various prefectures and the military and horse supervision departments of various prefectures. There is no plan to move these places in the short term.
grassroots governance structure.
However, the Sikong Mansion had no such scruples at all when it came to rebuilding the social governance structure in the newly recovered areas.
Before the recovery of Heluo, Zheng, Bian, Chen Ying and other places, the vast majority of the 2.6 million people were forced to endure brutal exploitation and enslavement as expatriates. They suffered the pain caused by the war and now participated in the reclamation.
, are very motivated to integrate into the new system, and recognize from the bottom of their hearts Sikong Prefecture’s local jurisdiction and governance.
The prisoners of war and children of the Han army had to undergo transformation. Thank God that they were not bloody purges.
Originally, the gentry and rural tribes in these places had either fled long ago, and those who chose to surrender to the Red Husbands in order to preserve their family property gradually became the agents of the Red Husbands or surrendered to the Han army to govern the places, which was destined to be the purge of Sikong Mansion.
object of repression.
Of course, there are also some gentry and rural tribes who participated in the resistance against the rebels, or a group of gentry and rural tribes who fled south joined Chushan. However, these people are either relatively open-minded and have family and country in mind, or they have completely accepted the transformation and accepted the
New Deal thinking.
Therefore, Xu Huai can completely operate Heluo, Zhengbian, Chenying and other places as experimental fields for the implementation of the New Deal from the grassroots level of social governance.
Shaolong won the great victory in Yingzhou in the seventh year and took the lead in promoting the construction of villages on the north bank of the Ying River. In the winter of the eighth year of Shaolong's reign, he recovered Heluo, Zheng, Bian, Xusong and other places. The construction of new villages was further promoted to the entire Luoyang Prefecture, Shaanxi and other places.
Prefecture, as well as along the Guoshui, Sishui and Cai Rivers.
Of course, rebel generals such as Yue Hailou and Cao Shixiong took control of Heluo and western Jing and implemented the military household system, which objectively greatly promoted the recovery of agricultural production in these areas in the past ten years.
Of course, Sikong Mansion accepted all these results without politeness. The focus of the follow-up work is actually the adjustment and arrangement of various production relations and the launch of new construction projects.
By the tenth year of Shaolong, more than 20 million acres of official land had been added directly under the jurisdiction of Sikong Prefecture. Among the newly added official fields, the proportion of newly reclaimed land was very small, and more of it was the direct expropriation of cultivated land occupied by military households who surrendered to the Han army.
No, the most important work is to measure the land, determine taxes, allocate farming contract rights to households, and determine various field taxes and tenant rents.
Although households in Zheng, Bian, Xuchen and other places were expelled and enslaved, they basically continued to farm their original fields. However, in addition to all kinds of hard labor, almost 70% to 80% of the harvest earned from a year of hard work would be lost.
Having been exploited for various reasons, even though they still have to bear land taxes and tenant rent, the proportion of the harvest left in their hands has doubled.
This is the most obvious benefit.
Of course, the land tax and tenancy rent that Sikong Mansion can collect from the newly recovered areas every year is as high as tens of millions of dollars - there are not tens of thousands or hundreds of thousands of gentry and countrymen exploiting them, so many people
, even if they are engaged in simple farming, they can only bear so much tax, and the average tax that can be generated by a million people in Jianghuai and Jinghu, which are more prosperous and have weaving and other industries and commerce developed to a certain extent, is far higher.
Less than that, it is actually the rentier class in the middle that has embezzled too much.
However, in the past two or three years, in addition to the new tenant rents and land taxes in Hehuai, the Sikong Mansion also invested a total of more than 20 million yuan in money and grain for three consecutive years, mainly used to station soldiers and soldiers in the newly recovered areas.
Living conditions improved, millions of houses were built, weirs and embankments were built, and countless rivers and canals were built.
This has benefited the people of Hehuai and Huaihe who have suffered from exploitation and slavery for many years even more significantly.
In the past three years or so, Sikong Mansion has also used water resources in low-mountain areas such as Songshan Mountain, Wan'an Mountain and Xiong'er Mountain to build hundreds of large and small ponds, and built large-scale slope ponds with stable terrain in the mountains to accommodate a total of more than 800 new A factory complex for hydraulic turbines.
Eight new large-scale coal and iron mines were opened in the two wings of Songshan Mountain and the western foothills of Funiu Mountain.
In addition to the traditional prefecture and county post roads, Xiangcheng connected to Zhengzhou Zhiguan City via Xuchang, and Xingyang's sandstone avenue was also completed at the end of the 10th year of Shaolong's reign.
Of course, in order to save construction costs and time, bridges across large and medium-sized rivers such as Yingshui and Langshui are still connected by fixed pontoons instead of iron bridges that are costly and require a long construction period.
However, in the early stage, it was used as a military artery, and in conjunction with the Cai River connecting Wanqiu to the Bian River in the north, it was sufficient to transport grain, fodder, war equipment and other combat materials on a large scale to the northern route.
Now that Xu Huai wants to go to the front line to supervise the war, he will face many obstacles.
After establishing the Military Intelligence Staff Department, Xu Huai not only wanted to improve and mature the operation of the Military Intelligence Staff Department step by step, but also wanted to give Wang Xian, Tang Pan, Yang Qiye and others a broader space for growth and become truly independent. Although he is a commander-level figure, he is now trying his best to restrain himself from intervening in specific military deployments.
The New Deal and military construction were also implemented in an orderly manner by Changshi Yuan and Sima Yuan, which were in charge of Shi Zhen, Xu Wuqi, Liu Shiwang and others.
In the past two years, Xu Huai has mainly studied with Bu Laman, Xu Wenjing, Yu Chengzhen, Shen Lian and others to promote the integration of Chinese and Western arithmetic and physics. He also brought Wang Xuan and Liu Qiong'er together to participate in various key equipment and Improvement and improvement of component materials...
In recent years, the Coal and Iron Supervision Department, the Industrial Manufacturing Department, and the Ordnance Supervision Department have adopted a series of new technologies and processes such as the "sink smelting downflame method" and constantly introduced new ones. Nowadays, in various smelting technologies, the manufacturing of casting and forging devices, and various hydraulic equipment The manufacturing, application, and armament manufacturing of various weapons, armor, crossbows, and war equipment, as well as the manufacturing of heavy-duty carriages and boats, were all ahead of this era.
The industrial manufacturing system has also begun to take shape, and it has begun to overwhelmingly occupy the shipbuilding, ironware, ceramics, cotton, woolen textiles, papermaking and other markets in Jianghuai, Jinghu and other places. It has also begun to build Ye and Yangzhou to go to sea, and to go overseas on a large scale. Output - The industrial and manufacturing system has begun to take shape, not only creating a very considerable annual income, but also greatly improving the farming level in Beijing and Xiangzhou.
However, in Xu Huai's eyes, all this was so crude.
There is no systematic theoretical research, everything is mainly based on the summary of experience.
Xu Huai restrainedly let go of major military and political affairs. In the past two years, he put more energy into the construction of Biyang Academy. The focus was also to attract scholars such as Bu Laman to promote the integration of Chinese and Western mathematics and physics. He himself While studying various mathematics and science, he also personally taught Wang Xuan and Liu Qiong'er's two daughters, and was also responsible for the enlightenment of his second son Xu Zhen in Western learning. At the same time, he also summoned scholars who were expert in calculus in the past to try to integrate the Central Plains Calendar. Calculation, astronomical observation and Western mathematics are integrated.
Yu Chengzhen once actually presided over the construction of the water-borne armillary sphere. In addition to being very good at making instruments, he was also a contemporary master in the study of astronomy and diachrony.
Xu Huai had discussed with Yu Chengzhen very early on the world's understanding of heaven and earth. It was obvious that Yu Chengzhen was still stuck in the theory of Hun Tian and could not get out.
Although the mainstream understanding of the world's model of the heaven and earth has experienced development from the Gaitian theory to the Huntian theory, as early as the Qin and Jin Dynasties, astronomers also proposed a theory that "the sky is vast and without matter, and the sun, moon and stars all float in the void."
"In order to move and stop, Qi is needed," Xuan Ye said.
Xuanye theory is closer to the cognition that appeared in Xu Huai's memory fragments than Gaitian theory and Huntian theory. It even only needs to replace the concept of "energy movement" with the invisible gravitational pull between the sun, moon and stars.
It's closer to the truth.
However, in addition to the astronomical observation of the sun, moon and stars, the current world has reached a very accurate level. The construction of the water-moving armillary sphere is a concrete manifestation. At the same time, based on the theory of armillary sky, a complete set of mathematical calculations has also been formed.
Even though there are still certain deviations between actual astronomical observations and mathematical calculations, Xu Huai, who was poor at mathematical calculations in the past, could not forcefully use the revised version of Xuan Ye theory to brainwash Yu Chengzhen and others.
It's no use hitting them on the head with an apple.
Braman introduced mathematical calculations such as spherical trigonometry from Western science to the Central Plains, and actually provided the corresponding mathematical calculation basis for the revised version of Xuan Ye.
Although Xu Huai himself was not sure about this, he could ask Yu Chengzhen and others to take the lead in trying to perform mathematical calculations on the heaven and earth model deduced by Xuanye theory.
Anyway, these are included in the research projects of Biyang Academy.
As long as Yu Chengzhen and others are not forced to accept unfamiliar knowledge, they are still extremely interested in verifying such mathematical calculations with actual astronomical observations.
In addition to promoting the integration of Chinese and Western mathematics and physics through the practice of astronomy and calendar, Xu Huai has also focused on promoting the refined development of steel smelting, casting and forging in the past two years.
The advent of the iron-spine crossbow filled the coal and iron supervisors and ordnance supervisors with an overly optimistic atmosphere, but in Xu Huai's eyes, the iron-spine crossbow could only be regarded as a very rudimentary and crude metal elastic material.
Xu Huai named this type of fine iron spring iron, taking the meaning of trembling from the word "spring".
In the actual smelting of spring iron, the recovery degree of mineral processing, quenching, annealing and other heat treatments and the corresponding forging treatment processes is still relatively low. Naturally, it is difficult to say that the production is stable, let alone an ideal yield rate.
Now the Ordnance Supervisor can manufacture six to seven hundred crossbows a year, as long as they rely on quantity to win.
In addition, the iron-spine crossbows currently prepared are still too bulky, and are far from Xu Huai's original idea of "multiple layers of thin spring iron stacked to form a crossbow arm".
Of course, Xu Huai is looking forward to refining a real spring iron, thinking about making a spring as a force-accumulating mechanism, and then using the pendulum principle and the already-invented ratchet and pawl structures to try to create the spring that appeared in the memory fragments.
The pendulum clock - Xu Huai thought it must be an epoch-making product, and it could also push the empire's equipment manufacturing to a higher level.
It is a pity that the conditions for manufacturing such precise devices are not yet available. Within two years, the Ordnance Supervision and the Coal and Railway Supervision Supervision were able to mass-produce the rolling bearings Xu Huai needed.
The structure of rolling bearings is not complicated, and the benefits are not difficult to understand. The key lies in the ability to mass-produce bearing sleeves and balls or rollers with suitable strength.
At present, in addition to various types of tanks and heavy-duty carriages, hydraulic equipment has been developed on a large scale. Friction and loss at the joints of rotating parts have become a bottleneck that restricts the further development of Beijing-Xiang manufacturing industry and cannot be ignored even if you close your eyes.
Xu Huai promoted the integration of Chinese and Western mathematics and physics, and suddenly turned part of his interest to astronomy and calendar. Many people in the Sikong Mansion did not take it seriously. However, the trial production of bearings attracted great internal attention, and various departments also took the trouble to contribute.
Countless experiments have been conducted over the years, and a large number of trial products were even produced for testing very early on.
While everyone was looking forward to returning the capital to Bianliang as soon as possible, and expecting Sikong Mansion to launch further operations to recapture Hedong and Guanshan, until he could completely regain his homeland that had been occupied by his enemies for many years, Xu Huai put his main energy into a miraculous skill that everyone despised.
Of course, there are many people in Xiangyang who don't understand the art of obscenity and skill.
In January of the eleventh year of Shaolong, the thirty-two sets of piers of the Yuliangzhou Iron Bridge were officially completed. The embankments on both sides were dug. More than a dozen large ships were stationed between the bridge piers. Thousands of craftsmen stood on the deck and on the bridge piers.
Huge steel components weighing thousands or tens of thousands of kilograms are hoisted to the bridge piers for riveting and assembly - the huge rivets are also heated and semi-melted by the stove between the bridge piers, and then embedded into different components.
It is forged and fixed in the hole.
Only then did Xu Huai come to the bank of the Han River in the eastern suburbs of Xiangyang again, and watched with interest the construction site of the Yuliangzhou Iron Bridge in full swing.
Although the construction system in Beijing and Xiangzhou is still too crude and rough, he was able to witness the construction of the Yuliangzhou Iron Bridge with his own eyes, and it was he who pushed it forward, and he felt a sense of pride in his chest.
What he created is ultimately beyond the reach of the world...
Integration of Western mathematics and physics.
