After Puyishi left, Qin Chuan wanted to go directly to Taiyuan, but Wu and Wencheng suddenly came.

The purpose of these two people to visit Gujiaobao was to ask Qin Chuan to keep Zheng Chongjian's life.

Wu Yan and Zheng Chongjian have known each other for many years. One was a Jinshi in the 41st year of Wanli, and the other was a Jinshi in the 44th year of Wanli. After entering the court, they had many contacts. However, Wencheng did not know Zheng Chongjian. He was only entrusted by Jian Guoning and other Shaanxi officials, and came to Gu to ask for mercy for Zheng Chongjian.

Zheng Chongjian was an official in Shaanxi for many years and had known many demoted officials in Shaanxi for many years. According to Wu Yan, Jian Guoning and others, Zheng Chongjian is a gentleman with a good character and talent, and has extraordinary talents. If he is not killed, Wu Yan, Wen Cheng and a group of former court officials will try their best to persuade Zheng Chongjian to serve as the general.

In fact, Qin Chuan did not intend to kill Zheng Chongjian. He used to kill people to establish his authority, but now he has gained a foothold, and it will be of no benefit to him if he kills people randomly.

So, after hearing the purpose of the two, Qin Chuan pushed the boat and released Zheng Chongjian, who had been detained, on the spot, and asked Wencheng and Wu Qi to take him back to Loufan for good settlement. Part of his family was in Taiyuan and part of them were in Xiangning. After taking these two places, they could just take them together.

After handling all the affairs, Qin Chuan beat his horse and headed straight for Taiyuan again.

Liao Sanqin and Li Dingguo have arrived in Taiyuan. The two brought a total of 7,000 troops. In addition, the guards of Liu Youzhu's troops, Luo Ba tribes, and Qinchuan are now gathered in Taiyuan. The Guandi army in Yangqu and Yuci have reached 23,000, and it is not yet included Ren Liang's troops who are feinting the attack on Fenzhou City.

The total strength of the Ming army they had to face was likely to exceed 100,000.

In addition to recruiting, the artillery mobilized by Qin Chuan also arrived at the city of Taiyuan one after another, including six fortress cannons, twenty-three general Tianwei cannons, fifty-eight cannons in total, and more than two hundred small cannons in field battles.

Since then, Qin Chuan has piled nearly two hundred cannons under Taiyuan City.

This battle was the largest battle since his rebellion.

After the cannons were in place, they immediately joined the ranks of bombarding Taiyuan City. When Qin Chuan arrived, the bricks on the wall above the small north gate of Taiyuan City had almost all been peeled off, revealing the sturdy rammed earth inside. There was no one standing within a hundred steps on the front of the city, and the Ming army artillery within that area had completely lost its fire.

Seeing that the time was almost the same, Qin Chuan gave the order and the attack team that had already prepared began to head towards Xiaobei Gate.

The first thing to do is to build a bridge. The bridge has been built long ago. It is made of a log with dry shade. It is about eight feet wide and more than three feet long. It looks like a shield cart. There are inflatable leathers at the bottom to increase buoyancy. There are protective baffles made of logs on both sides to resist the Ming army's shells. There are wooden wheels at the bottom. Twenty-four strong Guandi soldiers hid inside, shouting trumpets to push the wooden bridge with wheels and heading along the official road towards the small north gate of Taiyuan City three miles away.

As soon as the bridge appeared, Taiyuan city center suddenly became nervous. The artillery far from the small north gate turned its guns, aimed at the moving wooden bridge, and then fired fire.

The Ming army's artillery was already very accurate. In a hurry, none of the cannons that could hit three miles away could hit the wooden bridge.

It was not until the third round of artillery that a shell finally hit the left baffle of the wooden bridge. The whistling shells broke a log that was thick with thighs on the left. A few muffled groans and screams suddenly sounded inside the wooden bridge.

Cases and casualties occurred.

Fortunately, the shell was bounced out by the log and did not penetrate into the wooden bridge. The Guandi army inside was only injured by the broken log.

The wooden bridge stopped on the spot, but after only a few breaths, he continued to move forward with a slogan.

The Guandi Army's artillery array was still continuing to bombard. Except for some artillery that continued to suppress the city at Xiaobei Gate, the other artillery aimed at the Ming army's artillery positions and opened fire.

After moving forward from the wooden bridge, a Guandijun was left on the ground, covering his calves screaming. His legs seemed to be broken by a broken log.

Two Guandi troops rushed forward in the rear formation and quickly carried him back to treat his injuries.

Qin Chuan, who witnessed the whole process, realized that he forgot to build a stretcher. This thing can greatly prevent the injured from being injured in secondary injuries when treating the injured.

Not long after, the wooden bridge was shot again. The shell hit the top obliquely and then bounced out obliquely. Except for the loose log on the top, no casualties were caused.

At this time, the wooden bridge had already entered a distance of two miles and had more Ming army artillery ranges.

"The three shield cars at the top set off." Qin Chuan issued an order in time.

The three shield cars that had been prepared in front of the formation moved in response to the sound, and the wheels were creaking forward.

These three shield cars were to attract firepower for the wooden bridge in front. The shield cars were equipped with three large iron barrels, and the Guandi army who were pushing the cart forward also had a pack of gunpowder on their backs.

After the wooden bridge is successfully built onto the moat, they will immediately start blowing up the door.

Some of the Ming army's cannons were attracted by the three shield cars behind, but the pressure on the wooden bridge did not reduce much. As the distance was closer, the wooden bridge would enter the range of more artillery artillery.

The wooden bridge was advancing intermittently during the baptism of artillery shells. Although the Ming army had only a few powerful artillery pieces and the other artillery did not pose much threat to the wooden bridge, the wooden bridge was only made of wood. The more shells it was hit, the greater the damage, and the casualties of the Guandi army inside became greater and greater. Two unfortunate Guandi army even were directly hit by the artillery and died.

Seeing that fewer and fewer people were in the wooden bridge and the speed of traveling slower and slower, Qin Chuan ordered another team of people to rush forward without hesitation, resisting the wood and inflatable leather, and continued to push forward in the wooden bridge.

After several rounds of intensive artillery attacks, the already dilapidated wooden bridge finally arrived at the moat of Xiaobeimen. The Ming army's artillery could not be fired downwards, and the above Xiaobeimen was suppressed by artillery. The Ming army could only poke out muskets and bows and arrows on the farther city wall to attack the wooden bridge.

The Guandi army in the wooden bridge ignored the attacks of the Ming army. When they arrived by the river, they came out one after another, turned the wooden bridge over, and then began to repair the wooden bridge with the wood and inflatable leather he had brought before.

They all had three layers of armor, two layers of cotton armor and one layer of iron armor. The Ming army's muskets and bows could not hurt them at all.

The only trouble is the Ming army's rockets.

They cleaned each other's rockets from their comrades and put out the flames on the wooden bridge so that the wooden bridge would not be burned.

After a simple repair, the Guandi army shouted a trumpet and pushed the wooden bridge into the water, pierced a few sharp wood at one end of the wooden bridge into the soil on the other side of the moat, fixed it and floated on the river surface. Then they collected wet mud on the river bank to smear the wooden bridge to isolate the Ming army's rockets.
