The Mongols had about 3,000 people, and the Ming army had about 1,600 people, but Sun Chuanting's 1,000 people were guarding the fort, and the Mongols were not good at attacking the city, and Cao Wenzhao was outside, and the Mongolian cavalry could not break through calmly, so the Mongols wanted to eliminate Cao Wenzhao first, but Cao Wenzhao did not confront the Mongols at all, but just kept a distance from them, so that they could not attack Yongxing Fort.

After a day of stalemate between the two sides, the follow-up Ming army rushed over, and Yang Lian's security guards have also arrived, at this time the Ming army has more than 7,000 people, the Mongols have a strong fort in front, and there are strong soldiers in the back, and the leader is dead, so the current leader, but also another brother of Yechi, sent someone to ask the Ming army to put a road out of the pass, expressing his willingness to sacrifice a large number of cattle and sheep to thank the Ming army, anyway, it is all empty talk, does the Ming army really dare to go to the tribe to get cattle and sheep?

Sun Chuanting passed the meaning of the Mongols to Yang Lian and others, Yang Lian just wanted to settle down as soon as possible, so he suggested that the northern captives be released from the customs, Lu Xuan thought that the northern captives were cunning, and they should hand over the cattle and sheep before they could be released, Cao Wenzhao said: "Let the northern captives hand over the cattle and sheep first, as long as their weapons are confiscated, they are not at our mercy." ”

Yang Lian said: "We should also be faithful to the Beiyu, if they hand over cattle and sheep, they should always fulfill the contract and let them out of the customs." ”

Cao Wenzhao replied: "Barbarians don't understand what faith is, so why bother to talk to them about faith and righteousness." Although Yang Lian disagreed, he did not continue to object.

After receiving the reward, Sun Chuanting laughed: "General Cao's words are exactly what I want, let's disarm first." So he told the Mongols that it was okay to go out of the customs, first disarm and then garrison outside the fort, and wait for the cattle and sheep to be handed over before they could leave the customs.

I didn't think that this time the Ming army didn't play cards according to the routine, and in desperation, I negotiated with Sun Chuanting, saying that I was not confident enough now, and I was afraid that there was no way to order the tribe to send cattle and sheep.

The two sides bargained for a long time, and finally decided to take 400 people back to get cattle and sheep by Su Bu Answer, but Sun Chuanting demanded that all the Mongols must first dismount and disarm, and then let Su Bu answer go back to get cattle and sheep.

So the Ming army began to collect the weapons and horses of the Mongols from both sides, and then asked Su Bu to choose 400 people by himself. After the selection was completed, let them enter Yongxing Fort with their horses, and as soon as they entered the fort, a group of Ming troops with swords and guns poured out on the opposite side.

Sun Chuanting said with a smile: "After thinking about it carefully, I think that there is still no need for so many people to get cattle and sheep, so many people stay here, your tribe will send cattle and sheep no matter what, just send a cavalry back to deliver the letter, what do you think, leader?" ”

The situation is stronger than people, and if you don't answer, you can't imagine that the Ming army has now become as untrustworthy as the Mongols, and their plans have completely failed, so they have to obediently hand over the horses, and only send a person to send a letter back to ask the tribe to send cattle and sheep to replace people.

Sun Chuanting asked Cao Wenzhao and Lu Xuan to take 2,000 people to guard Yongxing Fort, and then with a large number of captured horses, the Mongols were also tied with ropes and lined up in a row, and escorted back to Shenmu City together.

Sun Chuanting and Yang Lian had a disagreement about how to deal with these Mongols, and Yang Lian believed that the Mongols should stay in Shenmu first, and then send them back after the Mongols sent cattle and sheep as agreed. Sun Chuanting thought that these Mongols invaded the border cities, burned, killed, plundered, and did not kill the Ming Dynasty, but it was impossible for Shenmu to use the rice grain of the Ming Dynasty to supply the Mongols.

Yang Lian hurriedly said: "Then will the Mongols starve to death in Shenmu?" Heaven has the virtue of a good life, and Boya must not do this. ”

Sun Chuanting said with a smile: "Don't worry, Wen Ru, Chuanting has also read the book of sages, how can they starve to death?" ”

The two came to the place where the Mongols were imprisoned, Sun Chuanting said: "You don't know the power of the heavenly soldiers, invade our border, kill our soldiers and civilians, and the people want to kill you. ”

The Mongols clamored loudly, asking Sun Chuanting to get something to eat, he was about to starve to death, and no one paid attention to the matter of going to the coal mine to help.

Sun Chuanting said: "Since you don't want to, wait here for the ransom to be delivered, I believe that starving for ten days should be a trivial matter for the Mongolian warriors." Then he turned around and left.

Seeing that he was so tough, the Mongolian panicked, and hurriedly came out and shouted: "Lord Prefect, I am willing to go to the coal mine to help, can you give me some food before going?" ”

Sun Chuanting turned around and said, "If you want to eat, go to the coal mine first, and don't talk about anything else." ”

The Mongols couldn't, so they had to go to the coal mines to help. The coal mine is nearby, and when I entered the coal mine, the foreman said: "If you drag a basket of coal from inside, you will have a steamed bun to eat, so if you want to eat, go and haul coal." ”

Mongolians began to haul coal for steamed buns happy days, no exception, a person can generally drag seven to eight baskets of coal a day, the change of steamed buns will be enough for them to support the physical strength of hauling coal.

After 12 days, the Mongols finally brought cattle and sheep, according to the first situation, one cow for one person, ten sheep for one person, Yan'an Mansion in exchange for more than 2,000 cattle, more than 10,000 sheep.

After the exchange, Su Bu said to Sun Chuanting: "Governor Sun, our tribe has lost so many cattle and sheep this time, there will not be enough food in the near future, can the prefect lend us some food?" Next year we will definitely return it to you with cattle and sheep. ”

Sun Chuanting smiled and took out a roasted potato, asked him to taste it, and after he finished eating, he asked, "What does the leader think?" ”

"What is this, it tastes so good." ”

Sun Chuanting said: "This is a very good food, we call it potatoes, it is very hungry, if you are willing to provide us with labor, I can give them food, and I can also provide your tribe potatoes according to their labor, how about it?" ”

The tribe that did not answer quickly not only did not grab things this time, but lost a large number of horses, cattle and sheep, and if they didn't rob others this spring, they couldn't get through it at all, and the Ming army was so difficult to rob now, of course he wanted to find a way out. And Sun Chuanting saw that there was not enough labor to reclaim a large amount of vacant land, and he was also anxious, so the two sides hit it off.

Although the Mongols didn't know how to do farm work at all, but the only thing needed to reclaim the wasteland was strength, Sun Chuanting and Subua reached an agreement, and Sububu provided 3,000 Mongolians to Yan'an Mansion to reclaim the wasteland for three months, and Sun Chuanting provided him with an additional 3,000 stone of cooked potatoes, so that Subuda lost 3,000 people to eat, and got these foods, this spring should be able to survive.

Sun Chuanting reported the situation to the emperor, and Zhu Youxiao was very happy, thinking that Sun Chuanting had found a new way to live in peace with the Mongols. So he ordered Yang Lian and Cao Wenzhao to return to Beijing, officially renamed the Yan'an Army as the Qin Army, and transferred more than 200 grassroots officers of the Guards Army to join the Qin Army, and ordered Sun Chuanting to add the title of a military squire and ordered him to temporarily lead the Qin Army in case of captives.
