Li Su knew that his letter to Liu Bei would definitely be approved, so he didn't want to waste time.

After handing over the March memorial, he immediately began to prepare for the northward military farming, cooperated with Guan Yu and Ma Chao's western expedition to Liangzhou, and prepare for future post-war comfort work.

Even more than half a month before Li Su left, Li Su took care of Guo Yuan, the general of the Diannong Army, and headed from Zitong County to Wudu with a large number of supplies, weapons, immigrants, livestock, and boats.

The specific strategy is actually discussed with Liu Bei before Li Su returned to Chengdu last year. In the past six months, he has been constantly adjusting his plans for letter exchanges, so Liu Bei always knew it and felt very relieved.

As for why he used the Western Liang Dynasty to use Guan Yu, the governor of Liangzhou and Li Su, the governor of Yongzhou, at the same time, this is Liu Bei's own business. He thought it was suitable and others could not question it. For Liu Bei, the name was not important. The key was to take advantage of Li Su's mobilization this time and take the opportunity to implement the local official system reform of "abolishing the governor of the state and establishing the three envoys".

Due to the severe drought in Guanzhong last year, this year's Western Expedition against Liangzhou, military rations still have to be replenished from the wealthy Yizhou. Guanzhong region only needs to ensure self-sufficiency and then take down Guo Tai, Han Siang, Hedong.

The grain route from Yizhou to Longxi was naturally the road that Zhuge made northern expeditions to Qishan in history. Since there were no miracles such as "Earthquake of Emperor Gaozu's Appearance, the river was diverted for easy transportation", the transportation loss was still relatively large.

If Li Su rectified the transportation infrastructure in Yizhou, he would still be able to transport two and a half stones of grain from Hanzhong to Chencang when he set off.

Then, from Jiameng Pass, the transportation from Jialing River, the Qiang River and Baishui River, and the transportation to Dazhong on the border between Wudu County and Tianshui County by small boats, Lintao still has to bear the huge loss of "carrying three and a half stones from one and a half stones from one and a half stones". It was reduced by one or two percent compared with Zhuge Liang's loss in history, because the shipping conditions of the Jialing River have improved.

Considering the loss of transferring grain from the Chengdu Plain or Ba County to Jiameng Pass, in fact, it was finally transported from Chengdu to one stone to the Tianshui border of Wudu. The transportation from Ba County was slightly better, and one stone was transported from eight stones.

Fortunately, Yizhou has been rich in the past two years and has planted double-season rice for more than a year. Inside combat can at least maintain hundreds of thousands of soldiers in defensive battles, take the initiative to attack from the outside, and support the 100,000 troops to spend more than half a year. Li Su asked Zhuge Jin and the others to raise funds from multiple sources and dispatch the surplus grain in the treasury, but it was not difficult to get enough.

...

On March 20, Li Su held a pre-departure ceremony in Chengdu North, because the main immigration teams and supplies, including a batch of cotton seeds, cotton cloth, new cotton loom samples, and a large number of technical craftsmen, followed Guoyuan for half a month.

So Li Su only needs to bring five thousand soldiers, carry weapons, equipment, rations and lightweight. Considering that Li Su would go faster, he made an appointment with Guoyuan to arrive in Dazhong on the fifth day of April, and Guoyuan should have arrived two or three days earlier than him, settle the immigrants first and do a good job of welcoming.

When he saw him off, Zhuge Jin was still showing a worry and seemed to be reluctant. Li Su knew that he was questioning the logistics arrangements and felt sorry for wasting money and food.

Li Su also patted his shoulder and said, "Tiyu, I know, you are unwilling to see nearly one million stones of tax grain and large amounts of supplies being consumed. But I am also trying to make Liangzhou digest and stabilize as soon as possible after it is captured, so as not to become a quagmire that will hold the king.

What is a mere Guo Si? It is easy to kill Guo Si, it is easy to annihilate Guo Si's main force, and to break through the most important cities and counties occupied by Guo Si. But the difficult thing is to quell the Qiang Rebellion in Liangzhou and no longer betray the court. The Qiang people began to harm Emperor Huan, and they had to stop calming down for twenty or thirty years. They were not allowed to stop. They could not destroy the warlords who had left behind. They had to be governed from the production and lifestyle of the local people.

A year ago, I took the immigrants to Dazhonghe Tianshui to grow cotton, and taught that 10,000 or 20,000 households would become familiar with growing cotton in the dry, cold and sunny environment of the Hexi Corridor. A year ago, I would distribute these familiar hands to the Qiang tribes who surrendered, living with them, and assimilate the Qiang people to adapt to our production and lifestyle of growing cotton and wearing cotton coats."

Zhuge Jin smiled bitterly and toasted Li Su with a wine bowl: "I don't know what the envoy said, but I didn't expect to be so anxious and hasty. If I wait for an extra season of grain harvest, at least after the summer grain comes down this year, the output of Chencang and Mei County can feed Tianshui, so we don't have to spend so much more grain here. One stone of grain from Chencang is equivalent to four stones from Chengdu."

Li Su patted his shoulder with a cheerful look: "Well, that's all? Chengdu transports one stone of grain to Chencang, and then it's time to transport eight stones. Now it's directly transported to Dazhong, Tianshui, which is almost eight stones. We also save the Chencang people from going back.

You have to calculate the account this way: except for the future use of the grain in Yizhou to pacify Jingchu and Wuyue, it will not be used to efficiently support the battlefields of the whole country. Since there will be no need to use so much wealth to pacify Jingchu and Wuyue in the future, it is better to squeeze the remaining grains in Shu. The strategy of the king after he will settle Liangzhou in the future is to pacify the east with all his might. Guanzhong and Hedong have to deal with Sili, Hebei, Central Plains, and Yizhou have to deal with Jingchu and Wuyue. It is not cost-effective to let the grain go west and go back.

On the other hand, I know you think this year is too anxious, but we have to. First of all, let’s be anxious now. May will be in Dazhong, and Tianshui has a variety of summer wheat and cotton. Secondly, we can deal with Guo Si without distraction. That was based on the situation where the princes of Guandong are still in peace. Your Majesty and General Zhu Ye, seem to be as safe as Mount Tai, and maybe at any time... While there is nothing wrong with them, they will completely sort out Liangzhou. It is worth it!

What's more, the algorithm in your account just now believes that "only one stone of transporting ten stones or eight stones of grain arrives at Dazhong, Tianshui". This algorithm is also problematic. Because you calculated according to the algorithm of "the van and boatmen still have to return". But this time we are a one-way immigration. All the immigrants themselves play as husbands and will not leave when they arrive at the local area. The return ration you counted is actually equivalent to the food they ate for autumn harvest in the local area. After doing so, the loss is less than half.

Believe me, Shu is so stable, and the population will definitely grow rapidly. As long as it is peaceful, it is possible for Yizhou to become more than 10 million people in less than two generations. Today I will help you take away more than 100,000 completely landless poverty, and to give them land to a vast and sparsely populated area in the northwest. It will also help Yizhou relieve the pressure.

The land of Dazhong is already fertile. Yufuluhuchuquan has been operating in the local area for several years and can support tens of thousands of cavalry horses. Now it has been changed to pasture and farming, which has just accommodated 20,000 to 30,000 households. I have carefully calculated the choice of the place and the scale of the plan, not just thinking about it. How many people can be born in the local area and how many people can be used to farm and fallow are all under my plan."

Zhuge Jin was convinced by Li Su's far-sighted words and had no doubts anymore. He sincerely congratulated Li Suma on his success. Li Su has not been in vain in the past few months. He has long done solid work in terms of logistics coordination.

...

Full preparation is the basis for everything to be successfully implemented as planned. Li Su did so solidly that there were no surprises on the road worth recounting. About twenty days later, he arrived in Dazhong County with thousands of troops.

Guoyuan was indeed three days earlier than him, and arranged the work of dividing land for the people. So when he came to greet Li Su, Li Su inspected more than 20,000 poor households who had settled in their own positions.

The total number of immigrants this time was more than 20,000 households, nearly 150,000. They fully considered how many people had enough land to be vacated after Huchuquan left. In addition to being completely in Yizhou, these people also had other characteristics, that is, many of them were Qingqiang people from Wenshan County. As mentioned earlier, the barbarians in the mountainous areas of western Sichuan, including Qingqiang soldiers and Lao soldiers, and Liu Yan and Liu Bei had used them.

The Qingqiang people are from the snowy area in western Sichuan, and the Sou people are from the Yi people from the Daliang Mountains of Yueli County.

Because the Qing Qiang people in the snowy area of ​​western Sichuan are similar to the Qiang people in the Hexi Corridor, they are both "indigenous people in the mountainous areas on the edge of the Qinghai-Tibet Plateau", they use these poor people as the main force of immigration, on the one hand, have to travel less, and on the other hand, it is convenient for ethnic integration in the future and will not be too rejected by the Qiang people in the Hexi Corridor.

Li Su was not worried that the Qing Qiang in Yizhou would be assimilated by the Qing Qiang in Hexi Corridor, because the Qing Qiang in Yizhou would be better and better after Liu Bei's rule. Who would not want to live a prosperous life under the leadership of the rich ruler? This time Li Su encouraged them to immigrate, and gave them enough land without owners, and gave them a plowing ox, a donkey, mule, and a free set of farm tools to attract immigration.

For example, this is like in the 21st century later, only foreigners on the southern foot of Changbai Mountain would secretly come to join the Korean brothers in Yanbian, China, and there would never be any poor people on the opposite side of Yanbian (I am not referring to those who go to Lampang, that doesn't count)

After Li Su arrived, he took a look and was very satisfied with Guoyuan's efficiency: "Yes, just a few days ago, all the diligent Qingqiang immigrants have started to plow the land. They are so diligent."

Guoyuan said proudly: "What's the matter? I've been working on this for five years. From the Jialing River to the May Dulu River, planting to the barren land of Nanzhong, and then planting Linyi rice, and toxic cotton. I changed four places in five years. Now it's the fifth place in the sixth year. Dazhong is much fertile than the mountainous areas where terraced fields were opened in those years. It was originally a high-quality pastoral area that was managed, and it was a land for resumption. Now it's just a farmer's farming change.

After Huchuquan left last year, local officials had already sent people to organize rectification. Before we came this year, the newly appointed Wudu prefect Shejian had organized labor service to burn the dead grass here while it was dry in winter, and it had not waited for the spring grass to grow again. Now it can be planted directly. We strive to plant summer wheat and turbid cotton before late April, so that we can harvest it in September. In this way, the food transported with the army is enough to eat."

Li Su praised Guoyuan repeatedly, and Guoyuan was a down-to-earth person. After inspecting the situation of persuading farmers, Li Su remembered another incident and asked: "Where are the weapons that you asked the civilians to transport together? Those new pyramid guns and armor will be transported to Tianshui in a few days and delivered to General Guan and Captain Ma. They may have to go to war with Guo Si in May."

Of course, Guoyuan would not delay such transportation and errands. He just said lightly: "Li Jue died so miserably, what other storms can Guo Si make? General Guan and Ma Ziwei took action and killed chickens with a ox knife. In fact, if you don't have these equipment, you can win. The so-called Xiliang cavalry, fighting against the king's army, is simply vulnerable."

Li Su: "But compared with Li Su, Guo Si's advantage is that he can't beat him and run. Last year, Chang'an City was placed there, Li Jue could not walk, nor could he cut off the King's Grain Road. The Hexi Corridor stretched for thousands of miles. We are not afraid of Guo Si fighting with us, but we are afraid that he would put us in and harass our military Grain Road.

The southwest of the Hexi Corridor is backed by mountains and the northeast is a grassland desert, which can be detoured everywhere, but the defense cannot set up defenses everywhere. To ensure that the food channels are not lost, we must make complete preparations for "with thousands of soldiers in the grain protection team, they can defeat nearly ten thousand robbery cavalry." Essential soldiers, excellent weapons, and even vehicles transporting grain must be carefully selected.
