Sun Chengzong went on the road with Zhu Youxiao's expectations, and Li Xin, as Sun Chengzong's disciple, also followed to mix experience and qualifications, most people think that Li Xin is mixed experience and qualifications, but Li Xin himself does not think so, he hopes to give full play to his ability, convince people who are not convinced, and give them a great surprise, and prove that Zhu Youxiao's vision is very accurate.

Qi Jin took 30,000 Shenji battalion men and horses to train and march, all the way to Baoding, Handan, Xinyang, and went straight to Wuhan. By the beginning of November, the 30,000-strong army led by Sun Chengzong and Qi Jin had arrived in Wuhan, the purpose of the training had been achieved, and the accompanying 30,000 logistical personnel had also arrived.

Wei Guangxu, the governor of Huguang, led the chief military officer, the deputy generals, and the staff generals to meet with Sun Chengzong and inform the troops that many logistical materials such as ships and food needed had been prepared and could be activated at any time.

Sun Chengzong decided to take Chongqing first, because Chongqing was the first stronghold of luxury Chongming's rebellion, and secondly, after obtaining Chongqing, he could not only go south to attack Yongning, the old nest of luxury Chongming, but also go west to rescue Chengdu, and more importantly, after stabilizing Chongqing, it could be used as a logistics base. The Shenji Battalion is strong, and the premise is to ensure that there is sufficient material supply. In order to avoid defeat due to insufficient logistics supply, it is necessary to establish a stable rear base, as a military master, Sun Chengzong did not think about victory, and it is necessary to think about stability first, not to mention that Zhu Youxiao let him completely pacify Sichuan and establish a stable court rule.

Sun Chengzong and Qi Jin led the army from the Yangtze River upstream, and its difficulties can be imagined, and a Three Gorges made Sun Chengzong exhaust his brains, and the losses were not too serious, but in terms of time, it was delayed until the beginning of December. After arriving in Chongqing, Sun Chengzong did not let Qi Jin attack the city, but first sent troops to secretly occupy Jiangjin City, to ensure that Chongqing's defeated troops would not go up the river and then return to Yongning. After occupying Jiangjin, he sent troops to seize Bishan County, the purpose of which was to resolutely prevent Yu Chongming's troops from retreating southward, so as not to make a detour back to Yongning. After the encirclement was formed, Sun Chengzong began the campaign to seize Chongqing.

In fact, for the Ming army led by Sun Chengzong, Chongqing was not too difficult to attack, but in order to kill and injure as few innocent people as possible, Sun Chengzong adopted the tactic of encircling three and missing one. The Ming army went up the Jialing River, arrived in the northeast of Chongqing, divided the troops to the north gate and the east gate to add mortars, and ordered the soldiers to slowly approach the city wall, and then began to bombard the two city gates and the city walls within a range of 150 steps on both sides of the city gates.

Guarding Chongqing is the son-in-law of luxury Chongming, Fan Long, Fan Long believes that Chongqing is known as a mountain city, the terrain is dangerous, the city wall is strong, the Ming army wants to capture Chongqing must first besiege, and then it can be slowly captured little by little, it is impossible to capture Chongqing without half a year and six months. But if the Ming army attacked for half a year, Yongning's reinforcements would have arrived long ago, and Chengdu City would have been captured by the old man long ago, so this guy finished arranging the defense, and he was not worried about the Ming army breaking the city at all.

Sun Chengzong and Qi Jin each commanded half of their men and horses to attack the north gate and the east gate respectively. The tactics they adopted were the same, not the traditional siege method of arranging up teams to shoot arrows and erecting ladders, but to bombard the city with artillery within a hundred paces on each side of the city gate, and the city was bombarded by projectiles. After the ten rows of artillery bombardment, I can't see a rebel on the city wall, the city gate has been blown open, and I enter the city gate hole in five columns and three rows at intervals of ten steps, and immediately after entering the city, it becomes an assault formation of three five or seven three rows of front and back cover, and when I encounter a small number of rebels, I shoot directly with a row of guns, and when I encounter a large number of rebels, three squads of fifteen people per row immediately form a formation of a line of shots. The 'two-kicked' small artillery in the back was divided into groups of three, a total of three groups to carry out isolated strikes against the rebels' support units.

The result of the battle was unthinkable to the commanders on both sides, and Sun Chengzong and Qi Jin could not have imagined that it would be smooth. The speed of the rout that Fan Long couldn't have imagined. The east gate, the north gate is almost at the same time to break through, after ten rounds of artillery bombardment, the city gate is opened, the Ming army enters the city after the row of guns fire, within a hundred steps, almost no one can be spared under the row of gun shooting, the rebels holding spears and broadswords are either dead or wounded, the whole team is annihilated, and the brigade is heavily killed and wounded. In the face of the all-fire volleys of the Ming army, the rebels had no chance of contact at all. In two quarters of an hour, that is, thirty minutes, the rebels were completely defeated, and by the time Fan Long reacted and prepared to organize a retreat, it was too late, so he had to rush to the south gate with the remnants of the defeated army.

The rebels who flocked to the south gate in order to get out of the city first, crowded people on their backs, and then the Ming army's 'two kicks' small cannon arrived, and a volley of shots helped them solve the problem, so the rebels surrendered as a whole team, even Fan Long was not able to escape, this guy was a little too greedy, and he wanted to escape with a cart of silver, and the result was tragic.

Chongqing, which had more than 30,000 rebels guarded, was completely annihilated in less than an hour under the attack of Sun Chengzong and Qi Jin's new-style army, and the rebels who escaped from the south gate were intercepted in Jiangjin again. After the end of the whole battle, the casualties of the Ming army were almost negligible, more than 25,000 of the 30,000 rebel defenders were captured, and more than 4,000 were killed or wounded.

Treating the prisoners, Sun Chengzong and Qi Jin had some disputes, and they had to kill them all because of Qi Jin, while Sun Chengzong said that the imperial army was a benevolent and righteous army, and the prisoners were unknown and planned to be released. At this time, Li Xin spoke and demanded that the captives be handed over to him for disposal. Neither Sun Chengzong nor Qi Jin dared to underestimate Li Xin, because Li Xin was stuffed in by the emperor himself. Although they were Sun Chengzong's students, they also had great respect for Sun Chengzong, and they also had a very humble attitude towards Qi Jin, and they still didn't dare to underestimate this young man.

Then Li Xin told the two of them his plan, and the two readily agreed to Li Xin's request and handed over more than 25,000 prisoners to Li Xin's management. Why did Li Xin look for such trouble? It was because Zhu Youxiao said two words to him when he came, "attacking the heart is the top, attacking the city is the bottom", "collecting the hearts of the people and dividing the rich land". Li Xin pondered for a long time on the road, and finally understood why Zhu Youxiao specially called himself aside to explain this sentence, Sun Chengzongguan was too conspicuous and not suitable for this job, Qi Jin was a military general, so he couldn't figure it out at all. So, after thinking all the way, Li Xin finally came up with two slogans: kill extravagant Chongming, and slaves will not be poor. Follow the court, and the people are rich.

Li Xin asked his soldiers to divide the captives into several waves, one of which was a small group of people and small toasts, the middle wave was these thugs, and the largest wave was ordinary rebel soldiers. First of all, Li Xin asked them why they rebelled against the imperial court, and the answers were varied, some said that the imperial court collected too heavy taxes, and we had no food to eat, so they rebelled, some said that the imperial court discriminated against us Yi people, and encouraged the Han people to rob our land, and some said that the leader told us to come out, and we had to come out, otherwise they would kill us. Next, Li Xin asked them if they would be able to guarantee food after the battle, ensure that the leaders would give them land, and if they would not kill them casually in the future and buy and sell their children. Their answer was unanimous – no way.
