At first, King Chu Huai made an appointment with the generals, and the one who entered the Dingguan first was the king. At that time, the Qin soldiers were strong, and they often took advantage of the victory to chase the north, and the generals did not take advantage of entering the customs first. Only Xiang Yu resented the Qin people for killing Xiang Liang, and worked hard to ask for help, and was willing to enter the west with Pei Gong. All the veterans around King Huai said: "Xiang Yu is a fierce and cunning thief, when he attacked Xiangcheng, Xiangcheng killed him in a pit and killed him. All that has passed is destroyed. Moreover, the Chu army advanced many times, and the former King Chen and Xiang Liang were defeated. This time, we should send a loyal elder to support righteousness and go west. Tell the father and brother of the Qin State that they have been suffering from the harsh government of their lord for a long time, and if they can get a loyal elder to go, the autumn will not be guilty, and the Qin State will not be worried. Xiang Yu cannot be sent. Only Pei Gong has always been a lenient elder, and he can be sent there. “

King Huai did not allow Xiang Yu to invite, and only sent Pei Gong Xi to collect King Chen, and Xiang Liang's scattered soldiers to cut down Qin. Pei Gong took the road to Dang, went to Yangcheng and Gongli, attacked the Qin army's barriers, and broke the two small forces of the Qin army.

Three years of winter and October. Qi general Tiandu rebelled. Tian Rong helped Chu save Zhao.

Pei Gong defeated Dongjun Wei in Chengwu. Song Yi traveled to Anyang and stayed for more than 40 days without entering. Xiang Yu said: "Now Qin has been encircling Zhao for a long time, and it has reached an emergency juncture. We should quickly lead our troops across the river, the state of Chu attacks on the periphery, and the state of Zhao counterattacks inside the city, and we will definitely be able to defeat the Qin army. ”

Song Yi said: "No. Today, Qin attacked Zhao, and if he defeated, he was tired. I can bear the weariness. If I don't win, I will raise my troops and march westward, and I will definitely defeat Qin in one fell swoop. Therefore, it is better to sit and watch the battle of Qin Zhao first. Phi Jian is stubborn, Song Yi is not as good as the general, and the general is not as good as Song Yi. Because he ordered the army: "Those who are as fierce as a tiger, as ruthless as a sheep, and as greedy as a wolf, and who are too strong to be envoys, will be beheaded." ”

So he sent his son Song Xiang to Qi as the prime minister, personally saw him off to Wuyan, and placed a wine meeting. At this time, the weather was cold and frozen, and the soldiers were freezing and hungry. Xiang Yu said: "The soldiers and the soldiers attacked Qin, but they couldn't stay here. Now the people are hungry and poor, and the soldiers can only be half-fed every day, and the army has no food. If you don't lead troops across the river, you will eat Zhao and fight against Qin with Zhao State, but you will drink high here, saying what is the disadvantage of inheriting Qin, and attacking the newly created Zhao with Qin's strength, it will fall in a few days. The State of Zhao has been captured, what are the drawbacks? Moreover, the national soldiers are newly broken, King Huai is not at the table, and the soldiers who sweep the territory belong exclusively to the general, and the safety of the country is in this move. Now he is not sympathetic to the soldiers, but he is selfish and respectful, and he is not a minister of the society. ”

In November, Xiang Yuchen went to the general Song Yi, in the military tent, beheaded Song Yi, and ordered the army to say: "Song Yi conspired with the State of Qi against Chu, and the King of Chu secretly ordered Xiang Ji to get rid of him. He has now been beheaded. ”

At that time, all the generals were terrified and obeyed, and no one dared to support me. all said: "The first to establish the Chu State was originally a general's family." Today's general is chaotic, which is in line with the way of heaven. So they made an appointment to set up a project for the general Yu. made people chase Song Yizi Song Xiang, chased him all the way to Qi State, and killed him. Huan Chu also reported to King Huai of Chu, and King Huai made Xiang Yu a general.

December. Pei Gong led his troops to Li and met Gangwu Hou. Capture more than 4,000 of his army and merge with his own army. Jointly attacked the Qin army with the Wei general Huang Xinwu Manchu and broke the Qin army.

Therefore, Tian An, the grandson of Tian Jian, the king of Qi, went to Jibei. Save Zhao from Xiang Yu.

Zhang Han built a road along the river to transport food and wages for the king's army. Therefore, Wang Li's army had sufficient food and rushed to attack Julu. There are few soldiers in Julu City, Zhang Er has summoned Chen Yu to rescue many times, but Chen Yu considered that Qin Bingqiang had few soldiers and did not dare to move forward. After a few months, Chen Yu did not arrive. Zhang Er was furious and resented Chen Yu. Make Zhang annoying. Chen Ze went to scold Chen Yu and said, "At the beginning, my husband and I were friends with each other. Now Zhang Er and Zhao Wang Dan are about to die, and Mr. has tens of thousands of soldiers and refuses to save them. Where is the old vow of living and dying together? If you can keep your word, why can't you die with the Qin army? It will also preserve our vows of the day. ”

Chen Yu said: "I thought that even if I went, I would not be able to save Zhao and die in vain. The reason why Chen Yu did not die with Jun today was really to preserve his strength and avenge King Zhao and Zhang Jun in the future. ”

Zhang Yan Chen Ze swore to die with Zhao Guo, and Chen Yu made Zhang Yan Chen Ze lead 5,000 people to attack the Qin army first, and the whole army was lost. At that time, Qi Shi and Yan Shi both came to save Zhao. Zhang Ao also collected soldiers from the north, and more than 10,000 people came. They were all stationed next to Chen Yu's fortress, but no one dared to come forward to attack Qin.
