Du Chong thought that Liu Guangshi of Xuzhou was difficult to hold under the siege of the Jin soldiers, and it was likely that he would not be able to reinforce him, but would be destroyed and eaten by the Jin army, and deliberately hesitated. Liu Guangshi saw that the reinforcements did not arrive, so he simply left the commander Jin Sai to break off, and led the army to take out Xuzhou before the Jin army arrived.

Regardless of everyone's opposition, Zhang Jun ordered the whole army to attack, and insisted on mobilizing Du Chong, Zhang Jun, Liu Guangshi, Liu Guanglie, and Yang Weizhong to enter Xuzhou and start a battle with the Jin army in Xuzhou. Yang Weizhong met and persuaded: "Our army has been defeated repeatedly, and the training of soldiers is insufficient, in case of failure, the battle situation behind will be unmanageable, it is better to rely on the number of troops, with me as the mainstay, and the gold soldiers will come to me, and the other party will consume." ”

Yang Weizhong believed that although the Fifth Route Army had more than 100,000 people and had an absolute advantage in numbers, there was still a big gap between the combat effectiveness of the Song soldiers and the Jin soldiers; Du Chong listened to this and also spoke in favor: "After thinking about it, he said: "The soldiers are moving with profit, now Xuzhou is surrounded by horses and rivers, and the Jin army is charging into battle with iron horses, we are difficult to resist, and we cannot fight, so it is better to retreat to the land of Sizhou and wait for the opportunity." ”

Zhang Jun's face was gloomy suddenly, and he ordered Yang Weizhong to go to Yingtianfu to see King Kang Zhao Gou on the spot, and take over Yang Weizhong's army with Zhiyan. Zhang Jun didn't expect Zhang Jun's courage to be so great this time, Yang Weizhong was one of the best generals under King Kang's account, and he turned the tide several times, and was dismissed so easily; ”

Among the five route armies, Liu Guanglie and Liu Guangshi's brothers had the most neat equipment, and the two armies had taken the initiative to retreat all the way since the start of the war, and they had hardly fought head-on with the Jin army, and the equipment was almost the standard equipment of the original Western Army; in order to encircle the two, Zhao Gou once took all the materials from Kaide Mansion, Xuzhou, and Yingtianfu, including a large number of weapons. And Zhang Jun's first army was formed by merging the rest of the division and the army of the Daimyo's Mansion, and Du Chong's army was completely composed of King Qin's righteous army, and there were no weapons such as the divine arm bow at all.

But Liu Guanglie has the highest status among these generals, and he doesn't even pay attention to Zhang Jun on weekdays, and doesn't take Zhang Jun as a thing at all, so he changed color and scolded: "Fight for these things before the war, you might as well dismiss me and stack the formation, that's joking with the lives of his subordinates, we have so many troops, we should set up a wall to fight, use trenches and canals to limit the opponent's cavalry, and reduce our own casualties as much as possible." ”

Liu Guangshi then put down his face and shouted that he wanted to find Zhao Gou to judge, Zhang Jun actually gave in in front of everyone, and asked Du Chong, Zhang Jun and others not to complain, and first set up a camp in the southwest of Xuzhou; However, the officials crushed people to death, and they still prepared according to Zhang Jun's arrangement.

Wanyan Zongwang saw the arrival of the army, looked at the Song army's defense and laughed: "Although the Song army has many horses, they dare not fight in stacked formations, and there are no tall city walls, if you want to rely on these camps to defend me, it is really ridiculous." ”

Wanyan Zongwang took Wulin Jingtai as the left flank and Chi Zhanhui as the right flank, and waited for the opportunity in the middle of the road; Wulin Jingtai led 3,000 elite cavalry, detoured through the fields, and crossed the ravines to enter the Song army camp. Zhe Yanzhi also lacked these weapons, and immediately ordered the whole army to fight, Zhang Jun saw that he also led the army to meet, the two took the lead, surrounded Wu Lin Jingtai 3,000 people to fight, as the soldiers on both sides fell layer after layer, Wu Lin Jing Tai rushed left and right in the Song army, and still could not be killed.

However, the actions of the Song army made Wanyan Zongwang see the weakness of the Song army, pointed to the direction of Liu Guangshi's first army, which was shrinking its strength, and ordered the flag officer behind him to play the flag, and he and Chi Zhanhui's two armies went to Liu Guangshi's military camp separately. Ten thousand horsemen rushed into battle, around countless dust and smoke, in the Song army, I didn't know how many people there were in the Jin army, Jin Sai hated it in his heart, if Liu Guangshi listened to his own arrangement of the divine arm bow here, at least he could resist for a while.

However, Liu Guangshi put 500 divine arm bows in his own army, while Liu Guangshi's army and cavalry were in the rear camp, and Jin Sai's subordinates only had ordinary bows and crossbows, and in front of the Jin army with superb archery, but in the blink of an eye, they were suppressed by the arrows of the Jin army; Wanyan Zongwang's cavalry seemed to be divided into several teams, but they cooperated with each other tacitly, even if the cavalry in front suffered a slight loss, the cavalry behind or on both sides would quickly fill the position.

10,000 cavalry rushed to Liu Guangshi's Chinese military tent in one breath, and did not give Liu Guangshi a chance to breathe, but fortunately, Liu Guangshi had enough experience in escaping, and there were more than 2,000 cavalry by his side.

Liu Guangshi's army collapsed at the first touch, Wanyan Zongwang and Chizhan Hui Zongbi joined forces to cover up and kill, the morale of the Jin army was greatly boosted, and the two armies of Zhe Yanzhi and Zhang Jun could not resist; the Song army's more than 100,000 troops collapsed in an instant, the Jin army pursued with victory, the Song army suffered countless casualties, Du Chong was surrounded by the Jin army, and surrendered to the Jin army with more than 6,000 people around him. Zhang Jun retreated to Sizhou under the cover of Zheyanzhi and Zhang Jun, gathered less than 10,000 remnants, and sent people to inquire, only to know that Liu Guangshi collected the defeated army and retreated to Yangzhou, Liu Guanglie retreated to Zhenzhou, and the rest of Du Chong retreated to Yingtianfu under the leadership of Qi Fang and others.

Xuzhou and Huaiyang army fell again, Ying Tianfu was in chaos again, Kang King Zhao Gou ignored Zhang Wei's dissuasion, decided to leave Zhang Wei and Yang Wei loyal to defend the city, asked for help from Runzhou and Bianliang, and he and Wang Yuan rushed south with the army;

Zhao Gou believed that Yang Zhi would definitely send reinforcements, but it was difficult to say what kind of reinforcements, if Yang Zhi deliberately stayed on the way to the army, and waited for the Jin army to break through the city, he would be caught in the north like his eldest brother to find someone to cry to. Involved in the battle of the imperial system, thinking that the eldest brother Zhao Huan wanted to send the third brother Zhao Kai to the Jin Kingdom, and Zhao Kai ran directly to Taiyuan, Zhao Gou was palpitating.

Zhao Gou believed that it would be safe when he arrived in Zhenzhou, but he didn't expect the Jin army to chase and kill to Yangzhou, Zhao Gou hurriedly ran all the way to the Yangtze River with Wang Yuan and others, grabbed the boat, and crossed the river directly. Liu Guangshi heard that if the law was concocted, the chaos between the two armies caused 100,000 people to escape, Si Nongqing Huang Yi and the Ministry of Rites Shangshu Wang Yun were beaten to death by the people when they fled.
