Although Li Guodong informed the Ming court in advance that the Later Jin Dynasty would invade again in July, Chongzhen was really reluctant to transfer the main force of the Shanxi and Shaanxi government troops who were encircling and suppressing the bandits.

At this time, Gao Yingxiang had wandered to the Central Plains, blocked by the main force of the officers and soldiers, and then to Hubei, Hanzhong, and northern Sichuan. However, Hong Chengchou, who was stationed in Xining, was unable to free his hands to deal with Gao Yingxiang because Lin Dan Khan had aggressed the border. Gao Yingxiang defeated He Renlong and Zhang Tianli in succession, and captured Guyuan and killed Lu Menglong.

Although Emperor Chongzhen had the secret help of Li Guodong, who was "predicting the truth", was disturbed by the bandits. In order to deal with the re-invasion of the Later Jin army, he could only build a castle and recruit people to be strong. However, he was so poor that he could not even transfer the money for building the city. At this time, Chongzhen felt that he was almost forced to death. Chongzhen, who was only 24 years old, had one-third of his hair white.

The Later Jin army invaded again, and destroyed several castles in a row. Tens of thousands of troops arrived at the city of Datong.

Governor Zhang Zongheng, Xuanda Governor Zhang Zongheng, stood behind him, with Datong Governor Hu Zhanen standing behind him. Daming was prepared, but Datong City could not tolerate too many refugees, and most of the refugees were arranged to go to other cities. When the refugees entered the city, Zhang Zongheng sent people to investigate the refugees according to the kind reminder of the eunuch Wang Kun, and indeed found many spies from the Later Jin Dynasty.

"Eunuch Wang is very careful! Otherwise, this great harmony will be dangerous!" Looking at the teams of spies in the Later Jin Dynasty who were taken down, Zhang Zongheng said to Wang Kun with lingering fear.

Wang Kun said: "This is a common trick by Jiannu! He mixed into the people with spies, then cooperated inside and outside, opened the city gate and let the Jiannu army enter the city. If it weren't for this plan, how could Jiannu seize many cities in Liaodong?"

In fact, it was Li Guodong who reminded Wang Kun that he was careful of Jiannu spies, so that Wang Kun was prepared. After arresting so many spies, this was a great achievement. Wang Kun seemed to see Wang Chengen looking at him with admiration, and his status rose to the top and became the eunuch in the head of the imperial horse supervisor! Well, on that day, I have to reward Li Guodong well!

Yuetuo and Dorgon led their troops to the city of Datong.

Dorgon pulled his horse, looked up at the impregnable Datong City, and turned to ask Yuetuo: "Yueto Beile, how long will it take for our army to break through such a strong city?"

"Uncle Fourteen, just wait for the meticulous actions that have been mixed into the city. If there is no meticulous response, unless the Wu Zhenchao Ha soldiers from Lakong Youde from Liaodong come, they can bombard the city with heavy artillery. Otherwise, they will not be able to capture it for half a year." Yue Tuo replied.

"Then wait for the inner supporter!"

"Uncle Fourteen, we should not wait blindly. We should set up camps and center them on the camps, so that the Korqin cavalry can search for nearby villages and loot the population. If the farmers in Ming Dynasty do not leave the city, we will harvest all their food!"

The Later Jin army set up camps, with Baoyi Aha and the Tumotes acting as auxiliary soldiers, arranged city defenses and transported food and grass; the Jurchen soldiers were the main force, monitoring the Ming army in Datong, and the Korqin Mongolian soldiers accompanied some of the Jurchen cavalry to harass the Han people's villages everywhere, occupying all the farmland left by the Han people when they fled. Not long afterwards, the food would mature, and the Later Jin army would organize Baoyi to harvest all the farmland near Datong.

Many Han people who were unwilling to leave their hometowns were captured by the Later Jin army, all the elderly and children were killed, and young men and women were driven away, preparing to be sent to Liaodong as a Baoyi Aha.

"If Jiannu doesn't siege the city, what good plans are there to retreat?" Zhang Zongheng, who was anxious, asked about the good plans to defeat the enemy.

"Zhang Duchen, you can kill a group of Jiannu and hang the heads on the top of the city. Jiannu will know that the troops will be withdrawn soon." Wang Kun offered a plan.

Zhang Zongheng immediately ordered someone to take a group of spies from the Later Jin to the city, and then let someone shout to the Later Jin camp.

"Someone shouted at the head of Minggou City. Go and see what's going on?" Dorgon heard the voice and asked Yue Tuo to check together.

Arriving two arrows away from Datong City, Dorgon raised his head and saw a group of people tied to wooden stakes at the top of the city, with executioners of three or five large sizes standing behind them, holding ghost-headed swords.

"What is Minggou going to do?" Yue Tuo was shocked.

Only a Ming official on the top of the city shouted: "Many people in Jiannu were arrested in the city! All of them were executed!"

The executioner pulled out the wooden sign inserted in the back of the Hou Jinxiezhu, pressed the person to the ground on the city wall, raised his knife and fell, and a row of round heads rolled on the city wall, and blood splattered on the city bricks. Then the heads of the Hou Jinxiezhu were hung high on the flagpole.

"Datong can no longer be conquered, let's attack other small towns!" Yue Tuo said.

The next morning, the Later Jin army evacuated from Datong City.

Seeing the withdrawal of the Later Jin army, Wang Kun said in his heart: It’s a pity that the emperor doesn’t like us eunuchs, your majesty, how can you know that we eunuchs are the most loyal to you. Looking at the Chinese officials in the court, how many loyal people are there? If the emperor can reorganize the eunuchs party, how good would it be? If there really is that day, Li Guodong will definitely win over.

Li Guodong didn't know at all that he had become an important figure in the future eunuch party. He had already entered Xuanda at this time. He had not many soldiers and horses under his command, only two thousand cavalry and three thousand infantry, but his infantry were all horse-riding infantry.

Five thousand men left the Shabeigou Castle a month ago and entered Senei before the Jin army arrived in Datong.

After Li Guodong entered the barrier, he sent an order to Zhang Wei who was staying in Xiangling's military farm, and ordered him to bring two thousand infantry and four thousand auxiliary soldiers to Yungaishan between Xuanda.

The six thousand soldiers brought by Zhang Wei were all adapted from refugees. In addition to transporting food and grass, the most important thing for the four thousand auxiliary soldiers was to be good at digging trenches and building fortifications.

"Brother, we are all here. When can we build fortifications?" Zhang Wei asked.

"I don't rush to repair fortifications. I will introduce Jiannu into the valley at a critical moment. We will use a small number of troops to deal with Jiannu, drag them down, and then build a dirt city on each side to block Jiannu in the valley! This time we must wipe out a group of Jiannu!" Li Guodong pointed to the map and said.

"Report to General, forty miles west of our army, a group of Mongolian Tartars, about 3,000 troops were looting the villages of the people." He didn't receive any Malay newspaper at night.

"Okay, pick up the persimmons and pinch them. Let's eat a bunch of Mongolian Tartars first!" Li Guodong stood up and began to arrange a combat plan to annihilate the Mongolian cavalry.

On Matou Mountain, about forty miles away from Yungai Mountain, a Yebushui led by He Xing, the leader of the Sharp Knife, was ambushing in the mountains and forests. The Yebushui under Li Guodong's Yebushui activities ranged, almost covering the entire Xuanda. However, every time the Later Jin invaded, the first thing was to send scouts and sermons composed of Bayala soldiers to fight the Ming army with all their might. Many Xuanda Ming troops had already been destroyed by the Houjin sermons.
