Yan Yingyuan's civilian team came with more than ten four-wheelers. These four-wheelers were designed by Li Laoer. There were two high-rise thick logs in front of the four-wheelers. There were holes drilled at the ends of the two thick logs. Iron pieces were installed in the holes, and there was a rolling thick log in the middle. At both ends of the thick log in the middle, there was a thin-cut shaft fixed on the thick log on both sides. The shaft passed through the holes and was fixed with iron rods on the outside. Like the car, grease was applied to the sliding bearings to reduce friction.

A rope is hung on a horizontal log, with the end of the rope tied with a wolf tooth pat, or a city guard weapon such as a yaksha. The end of the rope is fixed to a winch lying horizontally on a four-wheeler.

Under the cover of shields, the people and the soldiers approached the earth wall.

The arrows like raindrops shot from outside were blocked by shields.

The earth wall is five feet high, and the three feet high wooden fence is the position of the wolf teeth two feet higher than the top of the wooden fence, so that the total height is ten feet high.

The wolf teeth patted out from above the wooden fence. A civilian man pulled a mechanism. The wolf teeth patted or yaksha slid down with the rope and smashed it downwards to the head of the Later Jin soldiers below.

A heavy object fell from a height of one meter. The hit Jin soldiers either burst into brains or were pinned into hornets' nests by wolf teeth.

The earth walls and wooden fences cannot be compared with real city walls. However, the city guard vehicles designed by Li Laoer, specially used to place wolf teeth and yaksha squids, use the bearing and lubrication principles to reduce unnecessary energy losses. In addition, the weight of wolf teeth and yaksha squids greatly increases the power of the city guard weapons, so that the city guard weapons falling in low heights have the same power as the city guard weapons falling on the real city walls.

After releasing the wolf teeth, the people in the civilians pulled the winch and took the wolf teeth back.

The lime bottle and the turbulent oil tank hit the ground like hail. The lime bottle injected with water exploded when heated and exploded like a small bomb, causing the Jin army to cry and cry for their parents. The turbulent oil tank hit the ground and immediately cracked, and a torch was thrown off the earth wall, and a raging fire immediately ignited under the earth wall.

Some Min Zhuang poured gold juice downwards, and the armored man's skin that was scalding up the ladder was so hot that he was blooming with flesh. The air was filled with a disgusting stench, and many armored people fell from the ladder.

Dorgon looked at the fierce offensive and defensive battle between the Ming and Jin armies from a distance. Seeing his side suffered heavy losses, he cursed: "Is this his daughter-in-law still attacking the camp? It's simply a siege battle!"

With a short earth wall, the Ming army continued to use defending weapons to kill the armored people, Baoyi Aha and Mongolian soldiers, and the bodies under the earth wall had piled up layer by layer. In addition, Baoyi Aha rushed to the foot of the wall with a mud-filled mabao, and was killed under the wall. The man and Mabao fell in the corner of the wall together.

Soon the bodies and macaques were piled up three feet high, only two feet away from the wooden fence.

At a distance of two feet, the Jurchens could climb up as long as they stepped on the corpse and maroons. However, a wooden fence blocked them, and the Ming army's spearmen kept stabbing spears from behind the wooden fence. The Jurchens' machetes and short axes could not reach the inside, and were constantly stabbed and rolled down from the pile of corpses.

Dorgon yelled at Du Laer and Hubiertu: "Let your people follow you quickly!"

Du Laer and Hubiertu were dissatisfied: The people of Korqin came to the Ming Dynasty to plunder money and not to die, why should they fight for your Jurchens?

Little did Dorgon know that Dorgon was also very angry: this time he entered the Ming Dynasty, the Jurchens fought fiercely and fiercely. How many gold, silver and treasures did the Mongols rob and rob? When they encountered tough guys, they would hide behind to watch the fun. If every battle was fought like this, when the Jurchens suffered too much loss, wouldn’t the Mongols turn against the Dajin in the end?

This is the Korqin Mongols who married the Great Jin Dynasty, and the Mongols of the Zarut tribe, Tumote tribe, Zhalai tribe, and Bahrain tribe are even more unreliable. If they see that the situation is not good, they might turn around and surrender to Lin Danhan.

Dorgon had to force the Mongols to be cannon fodder, and promised to give more slaves to the Mongols and reward gold, silver and treasures. At the same time, he also sent a command: "The first flag-climbing who climbed up to the top of the Minggou city will be upgraded to level three; the first person who climbed up to the top of the city can not only be promoted to a flag-climbing, but also awarded to Batulu; the first Aha who climbed up to the top of the city can carry the flag to become a naturalized person."

There must be brave men under the heavy reward. Baoyi Aha and the armored men rushed to the Ming army's defense line with desperate fears. They were beaten to death in front of the formation one by one. The one in front fell down, and the one behind rushed up again.

The Mongolians following behind also had their eyes red, followed closely behind the people of Baoyi and the armored man, desperately approaching the earth wall, shooting round after round of arrow rain.

The Ming army archers also shot light arrows, and shot Mongols who did not have much protection. The firearms and soldiers were used to deal with the Jurchens in armor. Both sides suffered casualties, and the casualties of the Later Jin army were obviously several times greater.

The Paoyi Aha in front of him, the armored people and the Mongols died, and Dorgon didn't feel sorry for him. When Baoyi died, as long as he returned to the outside of the pass, he could turn the captured Ming people into Baoyi Aha again. When the Paoyi died, he would go to the mountains and forests of Daxinganling and other places to take on the savages to act as the armored people, and he could invade Korea, and the captured Korean soldiers could also supplement the losses of the armored people. As for the Mongols, it was even more unrelated to Dorgon's affairs. Losing the Mongolians was better than losing the flag.

The two white flags attacking in the west were like waves, with crazy attacks one after another, and Sun Degong and Li Yongfang's artillery teams also pressed on them. The Folang machine and the tiger squat cannon aimed at the earth wall and bombarded desperately.

The whistling shells kept hitting the wooden fences. Some shells passed through the gaps in the wooden fences, causing the Ming army to fly in blood and blood behind them; some shells hit the wooden fences, causing the wood to shatter, and the wooden fences to break, and the broken wood pieces to fly in, hurting many Ming soldiers who were defending their deceased.

The Ming army launched artillery counterattacks, killing and injured Sun Degong and Li Yongfang's artillery teams.

"Report! The second line of defense in the west is in danger!"

"Report! The first line of defense in the east has been broken by the thief slaves, and General Cao Wenzhao was forced to retreat to the second line of defense!"

"Report! The first line of defense in the south is about to lose, General Yang Guozhu requested to retreat to the second line of defense."

From time to time, personal soldiers came to report to Sun Chengzong that the Ming army in Tongzhou was in a hurry on three sides.

"The two young generals Li Laoer and Cao Bianjiao in the west killed countless enemies, but the thief slaves have strong military strength, and they don't know how much capital they have paid for." Sun Chengzong sighed.

The personal soldier replied: "The two young generals fought bloody battles. From the first line of defense to the second line of defense, Jiannu's corpses were everywhere, and there were probably no less than three thousand corpses."

Sun Chengzong stood on the platform, and he saw the fierce war on the west side. So he stroked his beard and nodded, "If we blocked Jiannu's attack today, I'm afraid Huang Taiji would not dare to fight again tomorrow! He sent an order to the two young generals. If he could no longer defend, he might as well give up the second line of defense."
