The second line of defense was only a hundred steps away from the first line of defense, but Li Laoer did not let the Ming army run into the second line of defense with his back to the enemy, but instead formed a formation with swords and cards, and walked backwards. The bird gunner and three-eyed gun behind him shot out projectiles from time to time, knocking down dozens of approaching Later Jin soldiers.

Li Laoer and more than a dozen archers climbed an arrow tower in the second line of defense, climbed high and shot arrows. The heavy arrows shot from a high point were extremely powerful, and almost every arrow could take the life of an Later Jin soldier.

The Ming army walked backwards and slowly retreated into a traffic ditch. At the end of the traffic ditch, there were two thick wooden doors. The Ming army retreated into the door, and the thick wooden doors were closed, and sandbags were piled up behind them, blocking the door.

The Later Jin army chased into the trench, but who knew that the Ming army's Buddhist general artillery and tiger squat cannons arranged above both sides of the trench fired one after another, aiming at the trench with dense cross firepower, causing the Jin soldiers crowded in the trench to fly and fall down in piles.

Then, behind a wooden fence beside the front wooden door, a black muzzle stretched out and aimed at the trench. Only a loud "boom" was heard. A large black iron ball weighing seven or eight pounds rushed out of the white smoke, dragging the faint smoke and crashed into the back Jin army crowd.

The golden armored man who rushed to the first one saw the iron ball flying towards him, subconsciously blocking it with the wooden shield in his hand. He heard a harsh sound of wood shattering, and the wooden shield exploded in an instant. The large iron ball wrapped in countless broken wooden boards and swept everything around him. The large iron ball directly hit the armored man. The thick armor on his body was as vulnerable as paper. The armored man instantly turned into countless pieces of broken flesh and blood, scattering around, and a burst of blood mist sprayed on the wall of the trench.

The broken shield fragments flew across like shrapnel, knocking down a piece of Later Jin soldiers around. The iron ball continued to advance with its remaining power, hitting an Eight Banner Tiger Spear, and the gun rod suddenly broke into countless pieces, causing secondary damage.

The heavy shells fired by the Red Barbarian Cannon bounced in the trench. The Later Jin soldiers who hit the worst were torn to pieces, and at the least they broke their hands and feet. After the shells penetrated several people, they hit the ground and jumped up, and then smashed two Later Jin soldiers. After they hit the wall of the trench, they bounced back to the other side, continued to knock over many people, hit the wall of the other side, and then rebounded again.

The shells were constrained in a narrow trench, like a three-dimensional pinball from the later electronic game city, running from the top of the traffic trench to the end, and opening a flesh-and-blood alley among the Later Jin soldiers.

Su Bai, who was commanding the attack of Zhengbai Banner at the forefront, discovered that the arrangement of the Ming army's positions was mysterious: the only passage was a trench leading to the gate, with two raised earth walls on both sides of the trench, and wooden fences were tied on the earth walls that were ten feet long. The trench was three feet deep and the earth wall was five feet high. The sum of the two was eight feet, which was almost equivalent to the height of the city walls of some small counties. When the Later Jin army attacked the gate along the trench, they would be attacked by three firepower.

The shell of the Red Cannon that just shot from the front took at least six or seventy lives!

However, the red cannon was loading very slowly because there was no fixed charge pack. After cleaning the cannon chamber, multiple gunners needed to erect the cannon weighing thousands of pounds, with the muzzle facing the sky before pouring the gunpowder into it. Then press the wooden board into the cannon chamber, then stuff the shells in, and compact it with a mop. Not only is the filling speed slow, but also because the loading volume is large, the wall of the cannon barrel is thick, and the heat dissipation is very slow. After firing three rounds of shells, the heat dissipation is required. The rate of fire can reach a tea time (fifteen minutes) and two rounds are good.

First, he was attacked by the cross-fire power of the small cannons for a round, and then he was bombarded by the red cannons. Almost all the Jin soldiers of Niulu were scrapped.

Seeing that it would cost too much to attack the gate, Dorgon ordered people to attack both sides of the traffic trench.

There are earthen walls on both sides of the traffic ditch, and there is also a trench in front of the earth wall. The earthen wall is five feet high and three feet deep. Attacking such fortifications is no different from siegeing a city.

So Dorgon asked to fill the second trench on the Ming army's defense line first, fill a passage, and then attack the earth wall, which would reduce the difficulty much.

The Later Jin army dug out the first earth wall and pushed the shield cart into the back of the first earth wall. The ground between the first line of defense and the second line of defense was bumpy, with many earth pits and many wooden stakes on the ground. The shield cart pushed forward a few steps and could no longer push it.

Su Bai pulled out the tiger-toothed knife, pointed to the bumpy ground and shouted: "Let the Ahamen go up! Fill the soil pit and cut off the wooden stakes!"

Under the supervision of the armored men and the archers, Baoyi Aha carried baskets of soil to fill the soil pits. Some Baoyi Aha held a short-handled axe and rushed forward to chop the wooden stakes with fear.

The Ming army naturally would not let Baoyi Aha finish his work easily. When Baoyi Aha walked out from behind the shield car, the firearms, tiger squat cannons, bird guns, turtledove-foot guns and other firearms on the second line of defense made roars one after another. Fire tongues spewed out between the wooden fences, smoke from behind the earth walls filled with gunpowders, and bullets swept across Baoyi Aha’s crowd like raindrops.

When he was picking up soil to fill the soil pit, he swung his axe and split the wooden stakes and was knocked down by large patches. He had dense blood holes on his body, and blood squirted, forming a gushes of blood mist.

Even the armored men who supervised the battle also suffered many casualties. Needless to say, the shells hit the body, and no armor could be stopped. Even if the bird gun projectile hit the body, a black hole with blue smoke immediately appeared on the thick cotton armor. The thick body fell down and a blood arrow sprayed out from the bullet hole.

Baoyi Aha was afraid of being beaten, so he threw down his work, turned his head and ran away. The armored man behind him waved his knife and slashed all the escaped Baoyi Aha's head without saying a word.

The second batch of Baoyi Aha who came up was frightened by the heads all over the ground, so he had to bite the bullet and fill the pits and cut the wooden stakes. I don’t know how much the price I paid, but finally cleared the road to the second trench.

The Later Jin soldiers continued to push the shield chariot and advance step by step toward the second trench. Almost every step the cart was coated and the Jin soldiers following behind had to step on a bloody corpse, covered with bloody and internal organs. The snow on the ground had already melted and solidified into red ice. Someone slid under his feet and fell to the ground. His mouth touched a heartbroken part. The Bu Jia immediately turned his head and vomited in big mouths.

The Later Jin army finally pushed the shield chariot to the second trench, but that was just beginning. The project of those who were waiting for the coat of Yi Aha to fill the second trench.

He had to fill the trench with a sandbag in his arms and had to leave the protection of the shield car. As long as he walked out from behind the shield car, he was immediately attacked by various firearms and bows and arrows of the Ming army, and a large body immediately lay down in front of the trench.

There were too many Aha who were driven in to fill the trench. The corpses and sandbags quickly filled the second trench. The Later Jin army was able to approach the trench, and the archers could approach and use strong bows to cover the shield chariots.

Dorgon watched his elite archers from the white flag approaching under the protection of the shield chariot, and he blew his bow and arrows, and rows of long arrows penetrated through the gaps in the wooden fence, and the screams of the Ming army sounded behind the earthen wall.

"It's almost broken!" Dorgon finally breathed a sigh of relief, feeling that paying such a great price was not in vain.
