After Chigu City arranged all the affairs of the Western Regions, Liu Bei led the women's army and the tiger and leopard cavalry to patrol around Dawan and Wusun, but there were some people who hated the Han and did not know the height of the sky and wanted to assassinate Liu Bei, but they all died under the Fang Tianhua halberd of a god-level bodyguard like Lu Bu.

Similarly, for these people, Liu Bei was not soft at all, Liu Hao in his previous life was a special soldier who killed people without seeing blood, and in the late Eastern Han Dynasty, he would not have mercy.

When Liu Bei returned to Chigu City again, he was surprised to learn that the Northern Xiongnu and Kangju had sent envoys from Gumo City to Chigu City respectively. Therefore, Liu Bei did not slack off at all, but summoned the two envoys separately.

As for the envoys of the Northern Xiongnu, they signed a non-aggression agreement with the Western Regions of the Han Dynasty, mainly because the Northern Xiongnu are now at a critical moment of destruction and Kangju, and they have no troops to attack Liu Bei, so they don't want to fight with Liu Bei.

However, the Kangju envoy hoped that Liu Bei could send troops to assist Kangju in defeating the Xiongnu, and since then, Kangju will submit to the Western Regions of the Han Dynasty for generations and become a vassal state.

Regarding this situation, Liu Bei did not decide immediately, but summoned Jia Xu, Zhang Zhao, and Tian Feng (Chen Gong had already served as a military advisor in Yan Liangwen's ugly army. Come and consult.

"My lord, this is a happy event, these should sign an agreement with the Northern Xiongnu, non-aggression against each other, and at the same time expel the Kangju envoys, so that after a few years of cultivation, you can send troops to pacify the Xiongnu in one fell swoop." As soon as Zhang Zhao heard about this situation, he immediately suggested.

"Lord, no, the Han and the Xiongnu are feuding, and the Xiongnu are persecuted here for my Han and Xianbei, at this time, if I sign an agreement with the Xiongnu in the Western Regions, how can he convince the people and civil and military officials?" Tian Feng hurriedly stood up and organized.

"My lord, in my opinion, the lord can expel the envoys of the Northern Huns, and at the same time order the Black Flag Army to rush to the aid of Wen Chou and Yan Liang, and at the same time order the public platform, if the Huns do not invade the border, then no matter how many soldiers the Huns have, they must not invade the Huns; And inform Kangju that my Western Regions will send troops to the Xiongnu, but whether we can defeat the Xiongnu depends on Kangju himself. ”

In fact, Jia Xu's suggestion is not vicious, but it intends to greatly deplete the troops of the two countries without helping each other.

At this time, it can be seen from the Xiongnu envoy that the Xiongnu did not have an absolute advantage in domestic troops, so it was almost impossible for the Northern Xiongnu to start a war with Liu Bei, and the Xiongnu border increased troops, but there was a plan to force the Xiongnu to divide the troops.

After the Northern Xiongnu divided the army, the pressure on Kangju was bound to be reduced, so that the two sides would inevitably fight evenly matched, so that they could fall into the swamp of war for a long time.

In this way, the entire western and northern regions will fall into long-term stability, slowly develop the Western Regions and accumulate strength, and then destroy the two countries with the power of thunder.

After listening to Jia Xu's suggestion, Liu Bei, Tian Feng and Zhang Zhao instantly thought of the trick, Tian Feng and Zhang Zhao stopped talking, and Liu Bei nodded happily.

After that, he glanced at Zhang Zhao quite intriguingly, and then thought of a sentence in "Romance of the Three Kingdoms": "Ask Zhang Zhao if you don't decide on internal affairs, and ask Zhou Yu if you don't decide on foreign affairs".

This Zhang Zibu is indeed very good in handling internal affairs, but in terms of strategy and external affairs, it is indeed as Sun Ce said, and it has not been able to give a good plan.

"In this case, the matter of receiving the envoys of the two countries will be handled in a peaceful manner, with Yuan Hao assisting, Zibu is still in charge of various government affairs in the Western Regions, and any problems will be reported to me at any time."

Seven days later, after Jia Xu dealt with the affairs of the envoys of the two countries, Liu Bei led two thousand women's troops, five thousand tigers and leopards and Jia Xu, Zhang Zhao, Tian Feng and others, and went through the canyon to Gumo City again.

At this time, it was already July, and in April, Liu Bei planted a potato in the back garden, and it should be harvest season.

As soon as he returned to the Duhu Mansion, Liu Bei went straight to the flower garden, but saw Cai Yan carefully taking care of the potatoes around the flower garden, and saw Liu Bei coming over, Cai Yan said excitedly.

"It's been a month since my husband went to Akiti City, and everything is going well?"

"Indeed, so far, everything is going well in the entire Western Regions, and in the next few years, there will be no big war in the Western Regions, but An Xing has been cultivating for a while, but the husband didn't expect that my family Zhaoji would actually start to become a small farmer?" Liu Bei teased.

"The husband laughed at Zhaoji, but he saw that the husband attached so much importance to this crop called potatoes, so he would take care of it for the husband when the husband was away, but so far I still haven't seen the fruit on this potato seedling!" Cai Yan said depressedly.

"Hehe, Akihime only knows one thing but doesn't know the other, the fruit of this potato does not grow on the branches, but in the soil." Then he bent down and peeled off the dirt, and saw huge yellow, orange and orange potatoes rolling out of the soil.

Seeing this, Cai Yan hurriedly took the basket from the maid's hand, and then helped Liu Bei pick up the potatoes and put them in the basket one by one, and in half a day, Liu Bei collected all these potatoes, and after weighing, Cai Yan was pleasantly surprised to tell Liu Bei that he had half an acre of land, but he got six stone potatoes.

For this kind of output, Liu Bei just smiled faintly, the six stone potatoes are only 720 catties, and the Eastern Han Dynasty at this time is only equivalent to half a catty in later generations, and one mu of land is only less than one-third of the later generations, so the yield of 600 kilograms per mu of potatoes is not considered a high yield, you must know that potatoes have a yield of about 2,000 kilograms per mu in later generations.

The main reason for this is that Liu Bei is not a real farmer, even in his previous life, he only had a general understanding of the cultivation of some crops, so the current Liu Bei cannot play the level of a farmer; Secondly, the agricultural fertilizer in the Eastern Han Dynasty was too small, and it could only rely on the manure of some people and animals, so it could not give full play to the yield of potatoes at once.

Although Liu Bei was not surprised by this, Cai Yan couldn't close his mouth happily, after all, if every batch of potatoes planted could have such a production capacity like now, then there would be no famine in the entire Han Dynasty in the future. Thinking of this, Cai Yan suggested by mouth.

"Husband, this is a good thing, why don't you invite your husband's subordinates to come and taste the potatoes together?"

"That's very good, Akihime will invite everyone to come to the Metropolitan Mansion to taste the potatoes in your name, and Akihime and I will cook it ourselves today."

After that, Liu Bei and Cai Yan worked together to give full play to the eating of potatoes, steaming potatoes, fried potatoes, fried potatoes, and burning potatoes, anyway, they tried to put all kinds of potato meals on the table in later generations.

When a group of subordinates arrived, there were actually few people, just a few people such as Lu Bu, Zhao Yu, Zhang Zhao, Tian Feng, and Jia Xu. When the people tasted the potato, they asked what it was.

Cai Yan did not shy away from telling everyone that this thing is called potatoes, and it has a yield of about ten stones per mu, which can be used as a staple food and a vegetable.

As soon as Jia Xu and the others heard that this was actually a production capacity of ten stones, they asked Liu Bei for verification, and their eyes were shining. Liu Bei smiled at this and told everyone that this was indeed the case.

"Lord, if this thing really has such a production capacity, it will not be able to spread out, even in the Western Regions, it will not be allowed to be planted by the people for the time being." Zhang Zhao suggested directly.

"Indeed, my lord, Zibu's words are really correct, this is a strategic thing, if it spreads out, it will be obtained by the people of the world, and he will not be able to benefit the lord in the future." Jia Xu had long known Liu Bei's idea of dominating the world, so he also suggested that Liu Bei keep this thing.

"However, if you don't let the people plant this thing, what's the use of this thing, although you know that as long as you start planting, it will definitely be known by others, but for the sake of the Western Regions, for the people, it is a helpless solution!" Liu Bei said wistfully.

"Lord, this matter is easy, isn't the lord a women's army established? The lord can expand the women's army, and at the same time divide the women's army into two groups, one group is led by General Zhao to be responsible for the safety of the lord's father, the master's mother and the capital, and the other part can be engaged in the cultivation of potatoes. But it was Zhang Zhao who continued to suggest pouring.

Liu Bei thought about it, it is true, planting is a relatively easy job, and as long as 10,000 troops can plant 100,000 to 200,000 mu, if it is 200,000 mu, it will completely produce 2 million stone potatoes, so supplemented by other meat, it can feed 100,000 troops, and at the same time ensure that the secret of potatoes is not discovered by others.

After Zhang Zhao's suggestion, Liu Bei arranged it.

"300,000 acres of land were set aside from Qiuzi County, the aborigines were relocated, and at the same time, 30,000 farmers were recruited in the name of the Metropolitan Protectorate, all of whom were widows and lonely people, and were supported by the Metropolitan Protectorate, providing remuneration, housing, and food, but all actions needed to be controlled."

Liu Bei planned to raise some tenants at this critical moment, because they were all widows and lonely people, so they usually didn't need to contact other people, so they could better keep secrets.
