When Li Laoer returned to Tongzhou, the Later Jin army did not dare to come to Tongzhou. Instead, they sent troops to attack Xianghe. As a result, they suffered a small loss at the city of Xianghe, losing more than a thousand surrendered soldiers, 800 coats and 500 Mongols, the Later Jin army gave up Xianghe and continued to plunder near the capital, conquered Yongping Prefecture, Qian'an and Luanzhou cities without fighting.

After Huang Taiji occupied Yongping Prefecture, he sent someone to negotiate peace with the Ming Dynasty, but was rejected by Emperor Chongzhen.

In March, Huang Taiji saw that Emperor Chongzhen refused to negotiate and was about to face spring plowing outside the pass, so he ordered the Later Jin army to withdraw from the pass. The Later Jin army, who had been looted in the Ming Dynasty for more than four months, brought more than 100,000 captured people, thousands of Ming army surrendered soldiers, captured two senior generals, Heiyunlong and Madunyun, as well as thousands of robbed livestock, the robbed food and gold and silver treasures filled with thousands of large trucks, and they came out of the pass in a mighty manner.

In the past two months, Li Laoer lived in Tongzhou and sent Ye Bucheng out from time to time to harass the Later Jin army. He did not dare to fight head-on with the Jurchen army, but it was still possible to harass the Mongols and won many heads.

The Later Jin army finally withdrew its troops, but the consequences of this Jisi Incident were very serious. The capital area was robbed by the Later Jin army, and the lives were damaged, and agricultural production was severely damaged, and a large number of people were captured outside the pass. One was rising and the other was growing, and the Ming Dynasty was hit hard. The abducted population went to the outside of the pass to serve as Aha, giving the Later Jin farmland and producing materials, which greatly improved the economic strength of the Later Jin. Moreover, the food robbed by the Later Jin from the Ming Dynasty eased the famine outside the pass.

The three generals of Zhao Rujiao, Man Gui and Sun Zushou, who were killed, greatly damaged the Ming Dynasty's military vitality. In addition, the Qinwang army in Shaanxi and Shanxi did not receive food and supplies. Later, the mutiny defected to the peasant army and even sprinkled a handful of salt on the Ming Dynasty's wounds.

The Later Jin, who tasted the sweetness of robbery, later invaded four more times, causing the Ming Dynasty to fall into a dilemma of fighting between the bandits and the Qing army, and eventually destruction.

Regarding Yuan Chonghuan's imprisonment and death, Li Laoer believed in his heart that Emperor Chongzhen did something wrong in handling this matter. Although Yuan Chonghuan deserves to be killed, he should not be killed at this time. Instead, he should use Yuan Chonghuan to negotiate peace with the Later Jin Dynasty to temporarily ease Huang Taiji. In addition, Yuan Chonghuan is actually negotiating with Lin Danhan, and he can appropriately pass Yuan Chonghuan to give Lin Danhan some benefits.

What Lin Danhan wanted was a city reward, that is, opening a tea-horse market, and exchanging horses, cattle and sheep for food and tea from the Ming Dynasty. If Emperor Chongzhen was smarter, he would simply let the greedy Donglin Party go to the border to trade with the Mongols. Everyone would be happy. Lin Danhan got the food, tea and salt he wanted. Moreover, the Donglin Party could also take the opportunity to suppress Shanxi merchants, the Ming Dynasty could also support Lin Danhan and use Lin Danhan to restrain the Later Jin Dynasty. The Donglin Party also made money and comforted Lin Danhan, so he did not need to waste Emperor Chongzhen's own inner treasury.

Emperor Chongzhen made two big mistakes. The first is that he should support the eunuch party after killing Wei Zhongxian and maintain balance; the second is that he frequently changed the cabinet chief, which accelerated the party struggle and cracked down on a group of capable and willing people in the Donglin Party. For example, Lu Xiangsheng was also a member of the Donglin Party, but he was cheated to death by Chongzhen.

After all, Emperor Chongzhen did not know how to play balance and finally killed a large number of capable ministers and generals. It was not that the Ming Dynasty had no talents, and talents were either cheated to death by Chongzhen himself or were cheated by Chongzhen to surrender to the Qing Dynasty.

In the past two months in Tongzhou, Li Laoer not only sent the Mongolians who attacked and plundered the people from time to time, but also seized more than 500 heads and rescued nearly 10,000 people, but also supervised the construction of three-year three-pound field guns in Tongzhou. This lightweight, fast loading and medium-power field gun was very popular with the Ming army. This kind of cannon will replace the 300-jin Folang machine in large quantities and will also become the standard equipment of the Ming chariot camp.

Moreover, the fixed charge pack and cork bullet holder invented by Li Laoer also increased the loading speed of the Ming army's Red-Yi Cannon. With these two magical artifacts, when loading the Red-Yi Cannon, there is no need to hold up the giant cannon weighing more than 3,000 pounds, and it can be loaded as long as it is placed flat. The procedure for loading a wooden board is omitted. The loading speed has been reduced from the original tea time (in ten minutes) to sixty breaths, and the speed has been increased by ten times!

However, the actual firing rate of the Red Cannon has only doubled, because after firing ten shells, it takes half an hour to cool down. Originally, the Red Cannon could fire about ten cannons within one hour, but now it can fire twenty cannons within one hour.

The Folang jungle cast by Li Laoer also received praise from the Ming army. The air leakage phenomenon of this new jungle has been greatly reduced, and its range and power have doubled.

During this period, Li Laoer's relationship with Portuguese missionary Lu Ruohan also furthered. He made a cream cake for Lu Ruohan. After Lu Ruohan tasted it, he praised it endlessly.

After the Later Jin army left the Jingji area, Sun Chengzong was preparing to go to Beijing to report his life.

"General Li, you have made great contributions to the Ming Dynasty. This time, you will at least be promoted to a guerrilla general. If your Majesty is very happy, it is possible to be named a gang general. As for someone in the court to prevent General Li from returning to the pass, I will definitely help the general fight this time!" Sun Chengzong smiled and touched his beard and looked at Li Laoer and said. He really wanted to take Li Laoer under his command and take him to Shanhaiguan to fight against the Later Jin Dynasty. After all, such a talent is rare.

Li Laoer didn't have much confidence in whether he could successfully enter the Ming system this time. He provoked Shanxi merchants, and I don't know how many people in the court were eager to get rid of him. Instead of living a nervous life all day, it would be better to be a non-staff member of the Ming Dynasty outside the pass and be a temporary worker. As long as this temporary worker is not pulled out to the tank, it would be fine.

"If the governor refuses to let the general return to the pass, there is no need to force the supervisor. The governor thinks that the general may be more useful when staying outside the pass for the time being. The general is familiar with Lin Dankhan and the Mongolian tribes. As long as the Ming Dynasty's closing door is open to the Ming Dynasty, the general can do more for the Ming Dynasty. And the general returns to the pass at this time, he is afraid of being plotted by some villains." Now Li Laoer is very open about whether he can return to the Ming Dynasty. Anyway, he will make contributions and will sooner or later enter the system.

Sun Chengzong sighed and said, "General Li, I will do my best to help you fight for it. If the court can agree to your entry into the Ming Dynasty, you will follow me. As for the Mongolians, I will give you a special envoy and you can negotiate with them. In addition, I will get you tea horse and salt induction for you, and you can trade with the Mongolians. Even if the court does not agree to General Li's entry into the Ming Dynasty, I will get you tea horse and salt induction for you, and let Xuanda's closing door be open to you at any time. By the way, General Yang Guozhu is the general of Xuanfu. If you need help in the future, you can find him. There is also the tiger power of Datong, and I will also help you establish a good relationship."

"Thank you for your kindness in the Supervisor!" Li Laoer knelt on one knee, clasped his fists and saluted Sun Chengzong.

Sun Chengzong said again: "It will take some time for me to return to the capital. General Li will help me to supervise the construction of more three-year field artillery. When I return to Tongzhou, I will send troops to recover the lost territory! Jiannu is still entrenched in the Yongping Prefecture area."

Lu Ruohan, who was standing aside, also said, "General Li, thank you very much for the cake you made for me. After I came to the Ming Dynasty, I have never tasted so delicious again. Don't worry, I will get you what you want."
