Xiang Yu divided the princes and on his way back to Pengcheng from Guanzhong, he recruited the troops of King Cheng of Han to increase his strength to deter the generals of Xiongxin (Emperor Yi) of Chu.
At that time, Han Wangcheng ruled in Korea for about a year, punishing good and evil, benefiting the people, saving punishment and taxes, and Han Min was very happy.
After sending Emperor Yi away and killing him, Xiang Yu detained Wang Cheng of Han, demoted him to Hou, and stayed in Pengcheng, intending to make his confidant Zheng Chang the King of Han. Han Wangcheng was first established by Xiang Liang, han xiang Zhang Liang and Xiang clan relations are not trivial, Han Wangcheng's Korea, should be a hardcore ally of the Western Chu state. The problem was that before Liu Bang entered the customs, he had helped Han Wangcheng to lay down most of the cities in Korea, and Zhang Liang led the Han army to follow Liu Bang into the customs, and Xiang Yu was extremely unhappy about this. However, Zhang Liang did not follow Liu Bang into Hanzhong, but returned to Korea to assist Han Wangcheng, and now also followed Han Wangcheng to Pengcheng.
When Xiang Yu was fighting in the State of Qi, he learned that Liu Bang had raised an army to the north, so he ordered the killing of Han Wang Cheng, in order to cut off one of Liu Bang's arms, and renamed Wu County, Ling Zhengchang, the King of Han.
Originally in Huiji County, thanks to Zheng Chang taking care of the Xiang clan, Xiang Yu was zhi en Tu. The problem is that Zheng Chang is not a Korean clan, his ability is limited, and he has not made many achievements in the anti-Qin war, and this kind of person is put in the chaotic world to be king, that is, to send people's heads. Xiang Yu kills people at will, and the use of people is also nepotism.
Looking at Xiang Yu Liu Bang from the perspective of employing people, there are also many brothers and nephews of Liu Bang, but none of them hold important positions in the army, and every time the generals under his command are added to the ranks and knights, they all remember their battle achievements clearly.
Xiang Yu also imprisoned Zhang Liang in Pengcheng, and when King Cheng of Han died, Zhang Liang went to liu bang. Xiang Tang, who remained in Pengcheng, not only did not stop him, but instead set up a banquet to send off.
In the Great War of Qin and Chu that year, Xiang Yan, the pillar of the Chu State, killed himself, his eldest son XiangQu was killed, his second son Xiang Liang was captured, and his third son Xiang Xiang was young and did not participate in the war, and took refuge under Zhang Liang's gate. The reason why Xiang Liang established Han Wang Cheng and treated Zhang Liang with courtesy was all because of his origins, but it was a pity that Xiang Yu cut off these connections.
Liu Bang's side was Luan Xiang Fengji, and he immediately made Zhang Liang the Marquis of Chengxin, worshiped him as a Taifu, and performed state affairs. For a while, Haojie returned to his heart, and the soldiers were greatly enhanced. Zhang Liang's military level was not good, but he was the sixth king, a banner, and reserved the hope of anti-Qin for the Six Kingdoms. Xiang Liang was also a banner, and to some extent Xiang Yu was also, so he looked down on Zhang Liang. Liu Bang was a scholar, and he honored Zhang Liang as a guest of honor, and the other princes were willing to honor the King of Han as a co-lord.
There was a man named Han Xin (the same name as the great general Han Xin) under Liu Bang's account, although he was not a member of the Korean royal family, he was also a clan and was not too far away from Han Wang'an's relatives. Liu Bang first made Han Xin a Korean lieutenant, allocated a group of Koreans to give him command, and when Han Xin took Korea, he officially crowned han wang. However, Zhang Liang did not want to be Han Xin's staff, although his grandson had six Han kings, and he also chose the Lord of Ming. Zhang Liang was now transformed from a Korean Shen disciple (Xiang Guo) to a Han Taifu and officially became an aide to Liu Bang.
The King of Han, the King of Sai, the King of Zhai, and the King of Changshan led 170,000 men out of Guanzhong and attacked Zheng Chang, the King of Han. The coalition forces attacked the Korean capital Yang Zhai, but to pass through the Henan state of Luoyang, the king of Henan, Shenyang, was originally a confidant of Zhang Er, the king of Changshan, and since Zhang Er had defected to Liu Bang, Shen Yang naturally joined Liu Bang's army.
In order to help King Zhengchang gain a foothold, Xiang Yu sent General Pu to Korea with him.
As early as 209 BC (the first year of Qin II), General Pu led 2500 people to raise an army in Xue County, and his starting point was no less than That of Liu Bang.
Soon after Xiang Liang raised his army, generals Yingbu and Pu each led their headquarters to defect. After the Battle of Dingtao, the Qin army invaded the Zhao state in a big way, and the king of ChuHuai made Song Yi a general, Fan Zeng a last general, and Xiang Yu a second general, saving the Zhao state in the north. The king of Chu came near and far away, leaving General Pu in Pengcheng and enveloping him.
After Xiang Yu killed Song Yi, he immediately sent someone to inform General Pu of reinforcements. General Pu led 4,000 troops to meet Liu Bang on the way north and helped Liu Bang capture Yan County. In Xiang Yu's view, General Pu was not as pure as Yingbu.
In the Battle of Julu, Xiang Yu sent General Yingbu and General Pu as the vanguard, led an army of 20,000 to cross the river and attack the Qin army Yongdao. The Battle of Julu was won by Xiang Yu, and the first negotiations with Zhang Handan broke down, and Xiang Yu ordered General Pu to attack the Qin army and fight south of Zhangshui, which was a great victory, and in this battle, General Pu was still the general who was familiar with Xiang Yu.
After Xiang Yu's army reached Xin'an with more than 200,000 Qin troops, Zhao Yingbu consulted with General Pu and killed them all overnight. General Yingbu and General Pu are like arms and fingers, which can be said to be Xiang Yu's left and right hands. At that time, Yingbu and General Pu supported the army and respected themselves, and their status was much higher than that of Xiang Yu's subordinates Long Ji and Zhong Lixuan.
In the process of destroying Qin, the first in Xiang Yu's friendly army was Yingbu, and General Pu ranked second. However, Xiang Yu was given the title of Prince of Jiujiang, Yingbu was made the King of Jiujiang, and General Pu did not even have a marquis.
Before Xiang Yu divided the princes, he had already planned to move the Chu king Xiong Xin (Huai Chu Wang) to Chenxian County, Changsha County, and kill him, Yingbu and the sword, Xiang Yu's shoes took a step forward, and Yingbu's long sword was always one step ahead. General Pu was different, often feeling the courtesy of the King of Chu, the most important thing was that he misjudged the situation. At that time, Lü Chen, Chen Bao, the King of Assist chu, Gong Ao, Zhou Yin and other Chu generals attacked the city strategically but did not follow Xiang Yu into Guanzhong. However, Xiang Yu's headquarters only had a few hundred thousand men, and Liu Bang, a powerful competitor, and there were many disobedient people in the princely states, and General Pu was opposed to Xiang Yu's attempt to kill the King of Chu.
Now not only Yingbu has sealed the King of Jiujiang, but even Zheng Chang, who has almost no military achievements, has sealed the King of Han. And general Pu, whose military merit was second only to Yingbu, was actually reduced to guarding the gate of the country for Zheng Chang, the king of Han.
General Pu was angry, but he was also a figure of wisdom and courage, how could he be at the mercy of Zheng Chang, and on the pretext of "facing the Han army", he went north to Sanchuan County, tun bing Hangu Guanwai.
One or two hundred miles east of Hangu Pass was a narrow strip of land, and the army could not be deployed at all, and as long as General Pu put his elite in front, the superiority of the Han army's strength was gone. Over time, the People and Horses of the Han Army's internal Cypriot and Zhai States may rebel against the water, and zhang Handan is still in ruins, and the variables are very large. If General Pu could block the Han army west of Hangu Pass for a few months, and wait for Xiang Yu to lead the main force of the Western Chu State to fight after conquering the State of Qi, Liu Bang would inevitably be in an embattled situation.
General Pu was obviously already in Xiang Ying's heart in Han, but he still had to create a pattern that was extremely unfavorable to Liu Bang, not for anything else, because he wanted to fight for the treatment after surrender.
In the cover of the Marquis of Fenghou, Liu Bang was much more generous than Xiang Yu, after Liu Bang called tianzi, he set the Eighteen Gong Marquis, the Pu general Chai Wu ranked thirteenth, and was named the Marquis of Thorn Pu, and the food was unknown, according to the ranking of about 5,000 households, which was comparable to Fan Duo, Dou Bao, Chen Ping, and Wang Ling. The above five people later held official positions of the rank of three dukes in the Han court, and Chai Wu and Dou Bao also worshiped the great general.
Being able to sit on an equal footing with such generals as Fan Duo and Dou Bao, General Pu achieved his goal and immediately turned his gun and led the Han army to attack Korea. So Korea was destroyed, and Zheng Chang died.
Liu Bang's seal of Han Xin, the Prince of Korea, was renamed Han Wangxin. Xiang Yu forced his hardcore ally South Korea into a sworn enemy.
