Zhang Han thought that the Chu soldiers were not enough to worry, led the Qin army to cross the Yellow River in the north, and joined the king who came from the north to reinforce the army to attack Zhao together, and defeated the Zhao army in Handan, and then Wang Li continued to surround the king of Zhao and rested in Julu, Zhang Han himself stationed troops in the South Thorn Plain, built a wall and a road, and transported grain and grass to the besieging Wang Liqin army. Chen Yubei of Zhao Guo collected Hengshan soldiers, got tens of thousands of people, and the army was in the north of Julu. Zhao Shu, please save Yu Chu.

The Chu army camp was divided into two routes, and one army went north to relieve the siege of the giant deer of Zhao State, with Song Yi as the general, known as the "Qingzi Champion", and Xiang Yu as the second general. Another army attacked Guanzhong along Henan, with Liu Bang as the commander. The queen of Chu promised that "whoever enters the customs first, the king." ”

Qi generals Tian Du and Yan generals Zang Di all went to save Zhao. Song Yi led the Chu army to Anyang, but he did not move and stayed for 46 days. Xiang Yu was anxious to attack the Qin army and avenge his uncle Xiang Liang who was killed, so he urged Song Yi to send troops, but Song Yi did not listen, ridiculed Xiang Yu for his courage and lack of strategy, and also ordered the army: "There are fierce as tigers, ruthless as sheep, greedy as wolves, and those who are too strong to make messengers are all killed!" "Sarcasm wants to kill Xiang Yu.

Song Yi sent his son Song Xiang to Qi to be the prime minister, and personally saw him off to Wuyan, drinking and having fun. At that time, the weather was cold, it was raining heavily, and the soldiers were hungry and cold, and Xiang Yu took advantage of this to arouse the dissatisfaction of the soldiers against Song Yizhi.

On the forty-seventh morning of Song Yi's immobility, Xiang Yu met Song Yi, entered his tent, and beheaded him to show the public. Xiang Yu immediately announced to the soldiers: "Song Yi and Qi conspired against Chu, and the king of Chu ordered him to be punished!." All the generals said: "The first to establish Chu is also the general's family; Now the general is in chaos. Huan Chu brought Song Yi's father and son to report to King Huai of Chu, and King Huai had no choice but to appoint Xiang Yu as a general and lead his troops to rescue Zhao.

Zhao Jun Chen Yu sent 5,000 people to try the Qin army first, and the whole army was annihilated. At that time, Qi Shi and Yan Shi all came to rescue Zhao, and Zhao Jun Zhang Ao also collected soldiers in the north, with more than 10,000 people, all of whom were next to Chen Yu, and did not dare to attack Qin.

The strength of the Qin army was 200,000 in Wang Li's army and 200,000 in Zhang Han's army stationed in the grain road, and the Chu army was only 50,000, which was far less than the Qin army. After carefully inspecting the situation, Xiang Yu decided to send 20,000 Chu troops led by Yingbu and Pu to cross the Zhanghe River and attack the Qin army's grain transportation road, and won several small victories, which made Wang Li's army lack food and Zhang Han's army exhausted, and was able to break Wang Li's army. Xiang Yu personally led the whole army to cross the river, and ordered to break the cooking utensils, scuttle the boats, and each person only brought three days of dry food, and the rest were burned to show his determination to fight to the death.

Inspired by Xiang Yu's leading soldiers, the Chu army was highly motivated and fought very bravely, breaking the army of Su Jiao, the brave general of the Qin army, in one fell swoop, forcing Zhang Han's army to retreat and withdraw support for the back of Wang Li's army. At this time, Xiang Yu turned over non-stop and fought Wang Li and the Great Wall Army of Shijian again, and won nine battles and nine victories. At that time, a Chu army could kill ten Qin troops, and Xiang Yu personally fought bravely to motivate the soldiers, "The cry of the Yu soldiers moved the heavens and the earth, and finally the Qin army was defeated." The Qin general Su Jiao was killed, Wang Li was captured, and Shijian refused to surrender and died.

Before Xiang Yu attacked the Qin army, although more than a dozen princes' armies such as Yan, Qi, Wei, Dai, and Liao had arrived in Julu to come to the rescue, they were all intimidated by the might of the Qin army, and they only stationed troops on the periphery and did not dare to fight. When the Chu army attacked the Qin army, the princes' armies from all walks of life were still closed, just watching from the camp, and when they saw the Chu army breaking the Qin army, all the princes' armies were frightened and bowed to Xiang Yu. Xiang Yu was the general of the princes from the beginning, and the princes and generals all belonged to Xiang Yu.

However, in the "Historical Records of the Three Families: Zhang Er Chen Yu Lie Biography", there is another saying about the princes' army: "Xiang Yu's soldiers are desperate for Handan, the king leaves the army and lacks food, Xiang Yuxi leads troops across the river, and then breaks the chapter." Zhang Han led the troops to relieve them, and the princes' army dared to besiege the Julu Qin army, and then captured Wang Li. Shibu committed suicide. After Xiang Yu attacked Zhanghan Grain Road several times, the princes' army participated in the siege of Wang Li, captured Wang Li, and forced Shijian to commit suicide, which was the common result of the Chu army and the princes' army.

, the princes' coalition army defeated Zhang Han's partial division with an absolute superiority in troops, and Zhang Han's army retreated. Zhang Han sent Sima Xin to Xianyang to ask for reinforcements, but Zhao Gao refused to allow it and sent people to hunt down Sima Xin. After Sima Xin returned to the barracks, the imperial court had been controlled by Zhao Gao, "The general will be punished for merit, and he will be punished for his ineffectiveness." Xiang Yu's Chu army defeated the Qin army in Sanhejin and sewage. Zhang Han was worried about Zhao Gao's persecution, so he led a Qin army of about 200,000 people with Sima Xin and Dong Peng to surrender to Xiang Yu in Yinxu.

After completely controlling the government and extremely ambitious Prime Minister Zhao Gao, who tried to establish himself as emperor, he sent his son-in-law Xianyang to order Yan Le to kill Qin II, who slaughtered all his brothers and sisters and became a loner.

After the death of Qin II, Zhao Gao summoned his ministers to inform him of the killing of Qin II, but found that the ministers and generals did not support him, so he had to welcome his son. However, Zhao Gao also left a hand, claiming that the Six Kingdoms had risen one after another, and Qin had lost control of the entire land of China. He said: "Qin was originally just a prince, and the first emperor unified the world, so he was called the emperor. The six countries are independent, and the Qin State is even more narrow, so it is not possible to call the emperor in the name of the emperor. It is appropriate to be the king as before. Therefore, Ziying should no longer be called "emperor", only suitable to be "king", and let Ziying fast, go to the temple to worship ancestors, and accept the national seal.

Zhao Gao called Ziying "King of Qin", in fact, in order to prepare for his continued usurpation of the throne in the future.

After fasting for five days, Ziying and his two sons and the eunuch Han Tan discussed: "Prime Minister Zhao Gao killed Qin II in Wangyi Palace, and he was afraid that his ministers would kill him, so he pretended to apply for justice and made me king." I heard that Zhao Gao actually made an appointment with the state of Chu and became king in Guanzhong after destroying the clans of the Qin Dynasty. Now let me fast and meet the Jongmyo because I want to take the opportunity to kill me at the Jongmyo Temple. I pretended to be sick and didn't go, Zhao Gao would definitely come to invite him personally, and Zhao Gao would kill him when he came. So, Ziying pretended to be sick and ignored the government. Zhao Gao sent people to invite Ziying several times, but Ziying didn't go, Zhao Gao really went to the palace where Ziying was located, and said: "Why didn't the king go to see Zongmiao about state affairs?" "Taking this opportunity, Han Tan stabbed Zhao Gao to death, and exterminated the three clans of Zhao Gao, and displayed them in Xianyang City. In the first year of Prince Qin, Liu Bang led a large army to break through Wuguan, captured the pass, and sent people to persuade Ziying to surrender when the troops were in Xianyang. At this time, all the ministers and officials also betrayed the Qin Dynasty and surrendered to Liu Bang. Seeing that the general trend was gone, Ziying tied himself with his wife and sons with ropes, sat in a chariot pulled by white horses, dressed in the white clothes worn by the deceased's funeral, and carried the emperor's jade seal, military talismans and other things, and surrendered in person from Yidao to Liu Bangjun, and the Qin Dynasty fell. The child reigned for forty-six days.

After Ziying surrendered, Fan Xu proposed to kill Ziying, but Liu Bang did not agree, but handed him over to the care of the accompanying officials. More than a month later, after Xiang Yu led the army into Xianyang, he immediately killed Ziying, set fire to the Qin palace, and carried out a massacre.

Yu Ji was brought to Dragon City, Yu Ji was immediately attracted by the prosperity of Dragon City, and was also attracted by Long Hui, Xiang Yu became the king of the co-king, named Long Hui as the king of the Dragon Kingdom, and more than a dozen cities around the Dragon City were the territory of the Dragon Kingdom. Soon Yu Ji became the princess of the Dragon King, and Long Hui also felt that he couldn't live with Xiang Yu, and he sealed the land and made other women.
