Zhuge Liang arrived in Changsha in mid-May.

I first went to Changsha County to talk with Liao Li for a while, spent a few days to understand the government affairs of Changsha, and then stayed for a few days to inspect the military camp to which Kou Feng belonged.

After doing these things, Zhuge Liang crossed the river in late May, came to the west bank of the Xiangjiang River, and found Zhangxi's station.

In late May, it was already the height of summer, and it was very hot.

But Zhuge Liang was in a good mood, and he saw a large area of slightly sparse rice fields.

Well, it's a little sparse, but it's a lot better than before.

Originally, it was either a water or a tidal flat, and even if rice could be grown, the yield would not be too high, and there was a possibility that it would be flooded in the event of heavy rain.

But now, Zhang Xi has cultivated more than a dozen hectares of rice fields here, built canals and drainage ditches, set up camps, and if he renovates a little and builds houses, it can be regarded as a small village.

Zhuge Liang was quite satisfied, and then found Zhang Xi.

As soon as he came up, Zhuge Liang didn't say anything about transforming the fields, but first told Zhang Xi about the changes in the current situation.

After all, Zhang Xi didn't really just need to be responsible for transforming the field, he was an important strategist under Liu Bei's group, and if there was any change in the situation in the future, Liu Bei would definitely ask for his opinion.

It would be better to tell him about this change in the external situation earlier.

The current external situation is mainly divided into two aspects.

On the Jingzhou side, Sun Quan and Liu Bei finally reached an agreement in February to exchange Jiangxia and northern Changsha for the southern county controlled by Jiangdong.

Needless to say, Nanjun is mainly the part that goes north to Linfu and west to Yiling, and the core is Gangneung City.

Changsha is bounded by Baqiu, the north belongs to Jiangdong Sun Quan, and the south belongs to Liu Bei.

After the land exchange, Sun Quan took Cheng Pu as the Jiangxia Taishou, settled in Shaxian, and set up Hanchang County in the north of Changsha, and Lu Su temporarily led the Taishou. Liu Bei appointed Guan Yu as a partial general, led Xiangyang Taishou, stationed in Jiangling, divided the land in the western part of Nanjun to set up Yidu County, and named Zhang Fei as Yidu Taishou.

But there is one thing that is very strange, I can't say whether it is a tacit understanding between the two sides.

Zhou Yu's title of Nanjun Taishou was not revoked by Sun Quan, and Liu Bei did not appoint Guan Yu as Nanjun Taishou, but directly gave Guan Yu the title of Xiangyang Taishou, which was still under Cao Cao's control.

Of course, there is hope that Guan Yu will capture Xiangyang in the future and inspire Guan Yu, but Zhou Yu. His twenty hectares of land in Nanjun seem to have really been sent early.

But even so, Zhou Yu was still recuperating in Chaisang, and he heard Sun Qian, who made Jiangdong, come back and say that Zhou Yu's body had roughly recovered, but now Sun Quan still had an actual job for Zhou Yu, so Zhou Yu was still recuperating at home.

This is the situation now after the Sun and Liu families changed land. Zhang Xi felt that in addition to Zhou Yu still alive, he had returned to the original historical line.

As for the northern side, Cao Cao finally made a big move.

After two years of recuperation, Cao Cao finally planned to use the pass to enter Hanzhong and attack Zhang Lu in January this year.

Then it caused a backlash from the princes of Guanzhong.

At this time, the Guanzhong region, Yongliang Prefecture, including the old capital Chang'an, has actually always been under the control of Ma Chao, Han Sui and others.

After all, Guanzhong is really dilapidated, and there is not much value of garrisoning, plus the large and small princes in the Guanzhong region are also nominally subordinate to Cao Cao, when Cao Cao fought and merged with the state high-level cadres, the Guanzhong coalition army also sent troops to help, so Cao Cao has not been free to solve this matter.

Now, Cao Cao ostensibly said that he was attacking Zhang Lu by using the road, but Cao Cao really thought that the princes of Guanzhong didn't know if they didn't study?!

Ma Chao is also a proper generation of famous people after General Fubo Ma Yuan.

Therefore, Cao Cao's move immediately caused a backlash from the princes of Guanzhong, who united with Han Sui as the governor, occupied Tongguan, and started a war with Cao Cao.

Then came the famous Battle of Tongguan.

By the time the news reached Jingzhou, the Battle of Tongguan had already ended, so the result was clear, Cao Cao won.

As for the process, there is no Xu Chu naked war Ma Chao, but Cao Cao was indeed killed by Ma Chao and abandoned his robe, so he escaped in embarrassment, and finally relied on Xu Chu to save him desperately, so he escaped.

At that time, in order to attract the attention of the Guanzhong coalition army, Cao Cao led his troops to cross the Yellow River north from the Tongguan Ferry, but secretly ordered Xu Huang and Zhu Ling to cross the Yellow River from Pubanjin west and enter Guanzhong.

Cao Cao didn't know what to think, so he actually let the large army cross the river first before Tongguan, and he only left a few hundred people on the south bank of the Yellow River.

Ma Chao saw that if he didn't take advantage of such a good opportunity, wouldn't he be too sorry for Cao Cao He personally led the cavalry out and went straight to Cao Cao's camp.

Cao Cao sat still at first, wanting to show that he would not mess with Xu Chu in danger, when was this, still pretending? !

Immediately dragged Cao Cao to flee for his life, this way to escape, chased all the way, Cao Cao couldn't stand Ma Chao's pursuit so tightly, had to cut his beard and abandon his robe, and finally boarded the boat under the cover of Xu Chu to escape.

Then, it was Cao Cao who wiped Han Sui between the books, which led to the disagreement of the Guanzhong coalition army, Cao Cao took advantage of the situation to defeat the Guanzhong coalition army in the covenant battle, and Ma Chao Han retreated to Liangzhou to protect himself.

After Zhuge Liang told Zhang Xi about this, he immediately made Zhang Xi feel that Cao Cao, this guy, was on the edge again.

In the Battle of Chibi, Cao Cao was defeated and retreated, but in fact, it did not have much impact on his own strength, most of the soldiers who died were soldiers who surrendered in Jingzhou, and what was burned was also Jingzhou's warships.

But the blow to Cao Cao's own prestige was very big, so in the first two years, Cao Cao had problems everywhere, either the family was ready to move, or some courtiers wanted to seize power.

Therefore, Cao Cao was stable for two years, just to clean up the internal relationship and stabilize the situation again.

Now as soon as he made a move, he defeated the coalition of the princes of Guanzhong, reoccupied Guanzhong, especially the old capital Chang'an, and returned to the control of Cao Cao, and his political influence was very great.

Zhuge Liang was also a little worried about this, worried that Cao Cao would take the opportunity to send troops to Hanzhong, defeat Zhang Lu, and then march to Yizhou.

Sun Quan wants to march into Yizhou, and Liu Bei can still find some way to stop it with the righteousness of the alliance, but if Cao Cao wants to enter Yizhou, then Liu Bei really has no way.

Zhang Xi didn't care about this, after all, it was not so easy for Cao Cao to defeat Zhang Lu, and if the Liangzhou Group behind him did not solve it, Cao Cao would not dare to go west to Yizhou easily.

One more.

"Has Fa Xiaozhi returned to Yizhou?!"

"Kaichun has already resigned with the lord, and now he has returned to Shuzhong, and the chief asks what to do?!"

Well, no why, just go back.

Wait until the next time Fa Xiaozhi comes, that is, he will bring the soldiers and invite our lord into Sichuan.

As for when, it will not be later than after this year's autumn harvest.

Zhuge Liang doesn't know Zhang Xi very well, and he feels that this guy is really chattering sometimes.

However, these things have also been said, and Zhuge Liang should also discuss with Zhang Xi the situation of this swamp transformation field.

On the one hand, Zhuge Liang wanted to know how much manpower and material resources would be needed to transform these 12 hectares of tidal flats, how much would it cost, and how much the expected annual harvest would be.

On the other hand, Zhuge Liang also wants to know exactly whether Zhang Xi's prevention and control methods can really effectively prevent and treat miasma.

If it can really effectively prevent and treat miasma, then Zhuge Liang will have to consider immigrating to enrich the four counties of Jingnan.

It is true that Jingnan is mountainous, and it is not false that Yunmengze is not easy to develop, but Jingnan is too little after all, and it will only get weaker and weaker if it goes on like this.

And one of the major problems that hinders Jingnan immigrants is miasma, and no one wants to come to this barren land to die.

If the problem of Jingnan miasma can be solved, then there will be no obstacle for Zhuge Liang to immigrate over, and if Zhang Xi can really change the swamp into fertile land, then it is a matter of time before Jingnan develops.

Never underestimate the desire for land in this era, whether it is a common person or a big family, they will not dislike too much land in their hands.

This is really a very important event, and Zhuge Liang can't help but come and see it in person.

Then Zhang Xi showed Zhuge Liang that since he came to Changsha, Zhang Xi had made various records and spent money and grain full of a room.

Zhuge Liang looked at the straight tooth flower.

"Yuan Chang. Why not streamline one or two?! Zhuge Liang flipped through a bamboo slip, glanced at it, and asked helplessly.

Zhang Xi shook his head and said, "If you put it in a concise way, I'm afraid it's not detailed enough. Xihanmen was born, and he can't do this! ”

This has nothing to do with whether or not you are from a poor family, right?!

Forget it, let's take our time.

Zhuge Liang spent nearly ten days to see a room of bamboo slips, and accompanied by Zhang Xi, he inspected the entire rice field and camp, and finally had a clear understanding of some of Zhang Xi's prevention and control methods.

The growth of the paddy field is okay, but the best paddy field is estimated to have a yield per mu that can reach the middle field, and most of them are the standard of the lower field.

This Zhang Xi also said, because it is the first year of transformation, he does not dare to spend great efforts to improve the fertility of the land, and it all depends on natural growth.

Zhuge Liang also knows this truth, and even for this output, Zhuge Liang is already very satisfied.

After all, it was just a swamp and tidal flat, and there was no way to grow food.

As for the water conservancy facilities, because of its proximity to the Xiangjiang River, Zhangxi has not done too much renovation, but has focused more on flood control and drainage, and has built a lot of drainage ditches to prevent waterlogging.

In terms of topography, the reason why these places have become swampy tidal flats is also because the terrain is too low.

It can be said that up to now, Zhangxi's experiment of transforming the swamp field has been preliminarily successful.

But Zhuge Liang combined with the records of Zhang Xi's room, and finally hesitated.

Without him, the cost is too high.

The labor cost of building land around the lake alone is extremely high, and 1,000 people have worked hard for almost half a year, but they have only made 12 hectares of inferior land.

You must know that twelve hectares of land is a lot for an individual, but for a force, it is really a drop in the middle, and even the annual output of these fields is not enough to feed these thousand people.

Of course, Zhuge Liang also knows that this is the upfront cost, and there will not be so much investment in the later stage, and it will also lead to an increase in the income of other industries with the development of towns, and labor costs can be greatly reduced.

However, the current Liu Bei Group really does not have so much manpower to mobilize.

Nanjun has just arrived, and it is too late to gather people's hearts, so it is impossible to rashly launch a large-scale conscription, and it is even more impossible to let the people of Nanjun come to Jingnan to serve conscription.

The Han Dynasty's conscription stipulates that the people who are conscripted to serve will only be within a hundred miles of the local area, and will not be levied beyond the territory.

And the number of Dingkou in Jingnan is really not optimistic, so that displaced people from other places migrate to Jingnan, and it involves the problem of miasma.
