Chen Mu is actually very open-minded about accepting students.
In the late Han Dynasty, the custom of "impermanent teachers" already existed. It was very common for students to learn from multiple teachers.
And essentially, this is a good thing.
In ancient society, there were often strong relationships between masters and apprentices, classmates and fellow villagers.
These kinds of relationships can easily form parties, supporting each other and criticizing each other in the court. For example, this is basically how a lot of chaotic parties emerged in the late Ming Dynasty.
The result of party strife is internal strife. A huge empire has countless government affairs to deal with every day.
However, due to party disputes and mutual disputes, the originally efficient central government has been in a state of downtime due to trivial matters.
If the country does not handle government affairs, it will cause great chaos in the local area, and eventually cause chaos in the world. There are countless things that have caused the collapse of a huge empire.
Therefore, it can be said that the emergence of "teachers are impermanent" can effectively prevent teachers and students from forming cliques. In the future, he will more highly recommend teachers and students like Taishan Academy who just watch the lanterns.
However, after persuading Pang Degong and Sima Hui to serve the court, not long after, at the end of July in the first year of Zhangwu, bad news came.
Zhang Xian, the former governor of Changsha, died of an illness. The illness came very suddenly. In less than two months, his originally healthy body seemed to have been drained dry. His whole body was as thin as a stick. He eventually fell ill and died soon.
A letter was sent to the court from Huanjie, saying that Zhang Xian may have been infected with miasma due to his long-term service as the governor of Lingnan, and the disease suddenly broke out.
Now that the plague has gradually begun to spread in the army, he plans to continue to elect Zhang Yi as the governor of Changsha and continue to attack Jiangling.
After getting this letter, Chen Mu finally knew the reason why Zhang Xian suddenly died of illness in history.
From ancient times to the present, Changsha, Lingling, Guiyang, Jiaozhou and other southern areas south of Jingzhou have been rumored to have miasma raging. It seems that the sky there is filled with poisonous gas, and people who pass by die one by one.
But in fact the so-called miasma is malaria.
The south is already hot, and the humid air causes an infestation of mosquitoes. Mosquitoes carry malaria viruses, which can be transmitted to people after biting them, making them sick.
Malaria itself is an infectious disease. Although it is mainly transmitted through mosquitoes and is less likely to be transmitted through daily contact, when mosquitoes are rampant, if one person is bitten, more people will also be bitten.
They spread rumors like this, saying that the south is filled with miasma.
Most of the soldiers Zhang Xian recruited were from his old troops when he was the governor of Lingling and other counties in Guiyang. Guiyang County was the Shaoguan and Chenzhou areas in later generations. In the Han Dynasty, it was a barbaric area with few people and where snakes, insects, rats and ants were rampant.
Except for ethnic minorities, few Han people live in those places.
Therefore, in ancient times, prisoners from the imperial court were sent to Lingnan, or officials were devalued to serve as officials there, which was called distribution.
Zhang Xian's rise this time was probably due to the recruitment of these old troops who themselves were suffering from malaria. They happened to be in the incubation period of malaria. After the army went north to station in Xiaoling, mosquitoes bit the soldiers with malaria and then spread it everywhere.
leading to the emergence of the plague.
Chen Mu had never known the cause of Zhang Xian's death before, nor did he understand why Zhang Xian gathered tens of thousands of troops and was defeated by Liu Biao overnight, as if they could not form a fighting force at all.
Now he understood that it was malaria, and in that case, there was a remedy.
Chen Mu immediately wrote a letter about how to defend against the plague and miasma. He told Huanjie that the source of the miasma was mosquito bites and asked him to retreat back to Changsha to stay there and deal with the plague and miasma in the army first to preserve his strength.
For the sake of the Lord, stop thinking about attacking.
The letter was sent to Xiao Ling by the people from the Military Intelligence Department quickly, because according to Huan Jie, the plague had begun to spread in the army, and if measures were not taken immediately, the entire army would probably collapse.
At the same time, this also let Chen Mu know that in history, after Zhang Xian's death, Huanjie elected Zhang Xian's son Zhang Yi as the governor of Changsha to continue to oppose Liu Biao. But it didn't take long for Liu Biao to easily defeat Zhang Yi. It seems that the plague and
The rampant malaria should be the main reason for the failure of their army's march northward.
But when talking about the plague, Chen Mu thought of another person, and that was Zhang Zhongjing, who wrote "Treatise on Febrile and Miscellaneous Diseases". If nothing else, he may be traveling around practicing medicine now, and writing this book will be of great value to future generations of Chinese medicine.
of ancient medical classics.
It is a pity that even in an era with developed transportation and smooth information, it is not easy to find someone who deliberately hides and does not want to get involved in world affairs, let alone in this Han Dynasty when transportation is not developed and information is not smooth.
The only valuable clue is that Chen Mu knows that Zhang Zhongjing is most likely operating in the southern areas of southern Jingzhou, southern Yangzhou, southeastern Yizhou and northern Jiaozhou at this time.
Because the north has gradually stabilized and infectious diseases such as plague and malaria have been effectively controlled, it is difficult for large-scale malignant infectious diseases to appear again.
A medical saint like Zhang Zhongjing would naturally appear wherever there was illness.
The Lingnan region has always been plagued by miasma and plague, so the probability of him appearing in the southern region is very high.
So Chen Mu planned to send someone to find it.
However, what Chen Mu didn't expect was that Zhang Zhongjing was actually not in Lingnan at this time but in Qingzhou.
Historically, he had already lived in seclusion in Lingnan at this time. Five years later, he wrote "Treatise on Febrile and Miscellaneous Diseases" and continued to consult in the south until his death in the late Jian'an years.
But now Zhang Zhongjing's whereabouts have changed. This is because he heard that there is a medical school in Taishan Academy in Qingzhou. They have summarized how to deal with the plague, so he traveled thousands of miles to learn from it and wanted to know if Taishan Academy had any cure for the plague.
ability.
But it was a pity that he didn't know until he arrived that Taishan Academy only had ways to prevent the plague, but no way to cure it. Even Hua Tuo could only treat it through some other methods, but there was no complete prescription.
This made Zhang Zhongjing very disappointed, but after he came to Qingzhou, he found that he was not completely without gains.
That is, after the development of glass technology, and after countless polishing experiments, the School of Physics developed a microscope that can magnify to 210 times. Under the microscope, people finally discovered the existence of microorganisms.
Many people think that microscopes are high-end products that will only appear in the industrial age.
However, we must understand one thing, that is, Leeuwenhoek was from the 17th century, and the industrial revolution did not appear until the 1760s, and there was not even a steam engine at that time.
So in fact, the early microscopes were completely polished by hand. For example, Leeuwenhoek polished more than 400 microscope lenses in his lifetime. The most powerful one was composed of two lenses, which could magnify the magnification to 270 times!
Therefore, in a sense, after Chen Mu had pointed out the direction, Qingzhou also spent a lot of manpower and material resources and polished it by many professional craftsmen to achieve 210 times, which was already considered a great failure.
However, it cannot be said that the wisdom of the Han people is inferior to that of the Europeans, because before Leeuwenhoek, the microscope had been invented long ago, and there were already references for various magnifications.
Qingzhou, on the other hand, started from scratch. It took decades of hard work to increase the magnification to 270 times. Qingzhou only spent a few years. Although it only has a magnification of 210 times, in comparison, through targeted research, it can achieve
This result can be said to be a very big breakthrough.
With the advent of the microscope, microorganisms appeared in front of the world for the first time, causing the entire medical school to boil.
Because Chen Mu had told Hua Tuo a long time ago that many diseases are caused by the invasion of certain microorganisms in the human body, including evil winds in traditional Chinese medicine entering the body, typhoid, wind-cold, wind-heat, etc.
At that time, people attributed the illness to wind, cold, and heat.
Now people know that what Chen Mu said is true. The reason why people get sick is because of these things called bacteria.
Basically, all the subjects that Taishan Academy should have are already available, except for biology. The emergence of microscopes has filled the gap in biology. The School of Medicine, the School of Chemistry, and the School of Physics have joined forces to start studying biology, matter, and various other subjects.
A detailed study of these materials ores was carried out.
It happened that Zhang Zhongjing failed to find a cure for the plague in Taishan Academy, but he vaguely felt that he had found the possible cause of the plague. He was very interested in it, volunteered to join the medical school, and began to conduct a large number of experiments using microscopes.
Naturally, Chen Mu didn't know all this. He thought Zhang Zhongjing was in Lingnan now and was about to send people to look for him.
After all, plague was rampant in the south. Cao Cao was defeated in the Battle of Chibi. In addition to burning Chibi, the northerners were not accustomed to the climate and the plague was also a big reason.
If Zhang Zhongjing can be found, and he already has a way to cure the plague, he can capture Xiangyang and march into Jingzhou, Yangzhou, Jiaozhou, Yizhou, and even Jiaozhi and other places, and there will be no need to worry about the plague.
As Zhang Xian died of illness and the army fell into the plague, Liu Biao's pressure in the south suddenly decreased, and Xiangyang began to increase its troops significantly.
Under this situation, Chen Mu could only call it quits and suspend his offensive against Jingzhou.
He left Zhao Yun to sit in Nanyang and asked Ma Hui and others from Pound Company to help take care of it, while he returned to Luoyang.
Zhuge Liang finally understood why Chen Mu didn't choose to postpone the attack south for a year. He actually knew that Zhang Xian would die of illness.
Many of the disciples who knew the whole story were even more in awe of Chen Mu. His ability to scheme against the common people, even if it was a conspiracy by gods and ghosts, was probably nothing more than that.
In August, Chen Mu took Jia Xu, Zhuge Liang, Pang Tong, Xu Shu and others back to Luoyang. While handling government affairs around the world, he arranged for them to either study with him or go to other departments to observe government affairs.
In early September, news came from Yangzhou that Yuan Shu had died of illness.
Cao Cao went south from Guangling and captured Danyang, and Sun Ce marched from Huainan and captured Yuzhang. Wu County is now in the hands of Yan Baihu. Historically, Kuaiji was occupied by Wang Lang who served as the prefect of Kuaiji, but at this time Wang Lang was not there, so the local people in Kuaiji
The powerful family dominates.
The Sun and Cao families met in Yangzhou and were eyeing each other's territory. However, both sides had serious concerns. They probably considered that the imperial court did not use troops against Jingzhou and were afraid that the snipe and the clam would fight for the fisherman's profit, so they did not dare to fight.
But judging from the fact that Sun Jian has been impeaching Cao Cao in the past few days, I am afraid that the two sides have already had some minor frictions in Yangzhou. Both sides are engaged in military campaigns and have thoughts and intentions of annexing the other side.
Chen Mucai was too lazy to care about the dog-eat-dog fight between the Sun and Cao families. In fact, after the imperial troops captured Nanyang but did not take advantage of the situation to attack Jingzhou, the Sun and Cao families had already withdrawn most of their troops. No one was afraid that they would be there.
When they captured Yangzhou, the imperial court suddenly gave them a pot of food.
After all, there are still more than 100,000 soldiers and horses surrounding them near Yingchuan, Qingzhou, Jizhou.
Judging from the overall situation, Chen Mu actually didn't worry about how much Sun Cao could do. They were trying to contain each other, be hostile to each other, and argue with each other. There was no way out at all.
It can be said that the best move Chen Mu made was to place Sun Jian in Yuzhou.
This blocked Cao Cao's way south, and at the same time prevented the Sun family from developing. Both sides looked at him with big eyes and small eyes, but they could do nothing.
The last move is to capture the north of Xuzhou, so that the entire Henan area will be within the monitoring range of Qingzhou.
Chen Mu didn't bother to take care of the Sun and Cao families at all, and the current situation in the north is that Liu Bei and Gongsun Zan have reconciled as before. The latest news is that the two cooperated to formulate tactics. Gongsun Zan led the troops, went out of Shanhaiguan, and pretended to attack Liucheng from the right road.
The so-called right road actually goes around the Yanshan Mountains, starting from Qinhuangdao City in later generations, along the coastline of Liaodong Bay of the Bohai Sea, passing through Huludao City, and then heading north from Jinzhou.
The advantage of this road is that it does not require climbing over mountains and ridges. It is a relatively flat road along the seaside. It has also been the only way from Liaodong to West Liaoning since ancient times.
This chapter is not over yet, please click on the next page to continue reading! Liu Bei, under the leadership of Tian Chou, led his troops out of Lulong fortress, followed the route taken by Cao Cao in history, and bypassed the rear to surprise Liucheng.
This combination of right and wrong gives the impression that Jiang Wei will be attacked head-on, while Deng Ai sneaks into Yinping and surprises Chengdu.
Chen Mu didn't know whether this attack would be successful, but he knew another thing.
Xu Rong has beaten Gongsun Du to a living. As fellow townsmen of Xuantu, the two used to have a close relationship, but now Gongsun Du is on one side and Xu Rong is working for the imperial court. Both sides are their own masters to some extent, and their personal friendship is weak.
A lot.
Gongsun Du's power was greatly weakened, and the help he could provide to Tadun was extremely limited. The Goguryeo Kingdom of Fuyu, which occupied the Heilongjiang area of Jilin Province in later generations, was at odds with Gongsun Du, so naturally he would not help them.
In this way, Tadun and Gongsundu are both mud bodhisattvas and cannot protect themselves when crossing the river. Unless there is some miracle, otherwise the army will press the border. I am afraid that Liaodong will be pacified by Liu Bei within this year.
Therefore, Chen Mu was not very worried about the Liaodong matter. He was now focusing on another matter.
When Guanzhong came to report, Han Sui and Ma Teng fought again.
The two sides joined forces with other warlords from Guanzhong and Xiliang, such as Liang Xing, Hou Xuan, Cheng Yin, Li Kan, Zhang Heng, Cheng Yi, Ma Wan, Yang Qiu and others to attack each other. In the Longyou area, Guanzhong Youfufeng,
The fighting in Zuo Fengyi's area was fierce.
What they didn't know was that as early as the beginning of this year, Guan Yu had disguised his main force as a food convoy, and his 50,000-strong army quietly crossed the Qinling Mountains and entered Guanzhong Chang'an, watching them coldly.
Sitting on the mountain and watching the tiger fight, the hand of the imperial court is quietly reaching out to Guanzhong!
