In Chengdu, since the rebels besieged the city, both sides have tried their best. Zhu Xieyuan first ordered the nearby officials and soldiers to collect grain within a radius of 200 li, and allowed the people to carry grain into the city to avoid the rebels. Then Zhu Xieyuan arranged to defend the city, I have to say that Zhu Xieyuan is a qualified official, he first guaranteed that he guarded the south gate, which was the most important place, let the inspector guard the east gate according to the imperial history Xue Fuzheng, the political envoy Zhou guarded the west gate, and the inspector made Lin Zai guard the north gate, and the stone pillar comforted Qin Liangyu with the famous ash pole soldiers to assist the most dangerous place at any time. Because the problem of the Ming Dynasty's army was ubiquitous, in order to ensure the morale of the soldiers, Zhu Xieyuan asked the king of Shu to help make up for it, and promised to ask the emperor to compensate for the loss of the king of Shu after the war was over. After Zhu Xieyuan's unremitting efforts, the defense of Chengdu City can be said to be impregnable, so that extravagant Chongming's attacks are always in vain.

First of all, Yu Chongming ordered the soldiers to wear cowhides and animal skin armor, climb the city with cymbals, pile up mountains outside the city, not slow to cover with thorns, and shoot crossbow arrows into the city, Zhu Xieyuan ordered the soldiers to attack with rockets (arrows are lit by strips of cloth with grease), and then sent people to dig Dujiangyan to flood with water, as a result, Yu Chongming had to retreat and find a way to build a bridge, which bought time for the defense of the city.

If a plan fails, he will use another plan, and extravagant Chongming will secretly send people to contact the traitors in the city, Zhu Xieyuan has long prevented this hand, and when he let the people bring food into the city, he arranged for his own soldiers to be screened, and when these spies were about to move, Zhu Xieyuan came to a net, detained and beheaded more than 200 spies, and then set up an ambush, so that Yu Chongming lost 5,000 elite soldiers. Zhu Xieyuan arranged for a death squad to risk death to protrude, kill the three Tusi warriors of Luxury Chongming, and burn down their wooden buildings.

All in all, Zhu Xieyuan is in danger and has a good schedule. The two sides fought wits and courage, Luxury Chongming tried all means to attack the city, and Zhu Xieyuan used all means to defend the city, the two sides were at a stalemate, knowing that the New Year was approaching, Luxury Chongming still couldn't capture Chengdu.

With the continuous victories of Sun Chengzong and Qi Jin's Shenji Battalion, the morale of the soldiers in Chengdu was high, and the morale of Yu Chongming's subordinates continued to decline. When An Bangyan rebelled, Yu Chongming was extremely excited, thinking that the Ming army would definitely be in chaos, but he didn't expect An Bangyan to be wiped out in an hour. After getting the news, Yu Chongming was like a mourner, so he had to arrange a defensive backroad, and stepped up the transfer of troops from various Tusi, striving to capture Chengdu before the Ming army arrived, so as to sweep the Chengdu Plain.

On the sixth day of the first month of the second year of the Apocalypse, Sun Chengzong and Qi Jin decided to send troops to Chengdu, and the matter of Guizhou was handed over to Li Xin. Li Xin was not ambiguous, so he sent ten groups of his own soldiers, each with 10,000 militiamen to various prefectures and counties in Guizhou, and swept away the territory of all the Tusi, chiefs, and leaders who participated in the rebellion. These militiamen are angry, and the old men who used to ride on their heads are now tied with ropes by themselves, and they are led around like dogs to criticize and fight, and when they are done, they will cut off their heads and divide their land, how relieving you say. However, they strictly complied with Li Xin's requirements, and those who did not participate in the rebellion and actively helped the court to quell the rebellion were not allowed to touch an inch of land or a grain of grain, and those who dared to violate it were to take back all their share of property. Li Xin is like a god now, no one dares not to listen to his words, if he doesn't listen, the land like the root of life will become someone else's, and the children and wives may also become someone else's. Li Xin was also afraid of being jealous, and he said that slander must be prevented, so every time he recovered a prefecture or a county, it was necessary to notify Wang Sanshan to send someone to manage it, and for every time he subdued a Tusi, he also notified Wang Sanshan to send someone to organize and arrange the lieutenant chief. However, in order not to prevent the incident of official coercion and rebellion, Li Xin also demanded that Wang Sanshan must use his black yarn hat as a guarantee, and the officials he sent must treat the Yi people, Miao people and other ethnic minorities equally, and informed Wang Sanshan of the model of the "Daming Official School" opened by Zhu Youxiao, so that he could also imitate this way to establish a "Guizhou Official School". Wang Sanshan is now obedient to Li Xin, and he does not dare to complain even if Li Xin is a little rude. This is Wang Sanshan's cleverness, in the face of the future nobles, he must now stammer, which also laid a good foundation for Wang Sanshan to enter the cabinet later.

With the concerted efforts of Li Xin and Wang Sanshan, the situation in Guizhou quickly stabilized. Now Sun Chengzong and Qi Jin's team has arrived in Shuixi, which is the territory of the most famous Shuixi clan. Here, An's rule has reached more than 1,000 years, from historical records, it already existed when Zhuge Liang went south, because he helped Zhuge Liang capture Meng and get an eternal reward, since then all dynasties have been as usual, including the founding Hongwu Emperor of the Ming Dynasty, An's is deeply rooted in Shuixi, which has to make Sun Chengzong and Qi Jin pay attention.

On the east bank of the Yachi River, the armies of Sun Chengzong and Qi Jin camped along the river and waited for battle, and the native soldiers of the An tribe on the opposite bank were preparing to cross the river under the leadership of Hao Shehui. An Bangyan's demise not only did not make the An clan settle down, but it instigated the hysterical woman of Luxury Shehui, and she gathered all the clansmen who could be mobilized to come and avenge An Bangyan. It was unreasonable to be an impulsive woman, a strong sense of revenge filled her brain, and the madness overwhelmed all her sanity, and the native soldiers, under her urging, rushed desperately towards the other side of the Yachi River as if they had smoked opium.

Facing the native soldiers who seemed to be crazy, Sun Chengzong and Qi Jin looked serious and calmly ordered the soldiers to defend. The soldiers were musketeers, each team of 400 men, divided into four rows, and when the native soldiers approached eighty paces, they took turns firing their guns. The "two-kick" small artillery mainly bombarded the dense crowd that had just crossed the riverbank, and the mortars bombarded the assembled native troops on the other side of the river. Using this method of warfare, after two rounds of bombardment, the native soldiers could only rush to the front of the musketeers, even if they rushed to a distance of fifty paces, they were powerless in front of the rows of musket bullets, and they could not reach the knives and guns, and the crossbow arrows could not be shot, so they could only watch them fall.

The attack of the native soldiers, which began in the morning, had killed and wounded nearly 30,000 people by noon, and the rebels who had died in the battle had filled the banks of the river, the artillery was numb, and the barrels of the musketeers were feverish, and the native soldiers on the other side had their troops collected for lunch. Sun Chengzong and Qi Jin also hurriedly ordered the logistics soldiers to immediately deliver food and replenish ammunition, and the wounded and dead front-line soldiers began to retreat, and those behind were replenished. Both sides were a little tired and began to rest, knowing that there would be a fierce battle in the afternoon.
