Liu Bang's army ceded Xianyang. Xiang Yu led the army into Xianyang City, burned the palace of the Qin king, burned the mausoleum of the first emperor of Qin, killed the prince of Qin who had surrendered, and destroyed the clan of the Qin Dynasty.

Everywhere the army went, it was a mess. The people of Guanzhong were very disappointed, because they were afraid of Xiang Yu, they didn't dare to disagree.

Xiang Yu sent people back to Pengcheng to report to King Chu Huai and ask for instructions. King Huai replied, "As promised," which means to do as agreed. King Huai successively used Song Yi and Liu Bang to contain the Xiang family, how could Xiang Yu not know.

According to the original agreement, Liu Bang should be the king in Guanzhong.

Qinzhong has been an imperial state since ancient times. The land of the Guanzhong Plain is fertile, and there is the danger of mountains and rivers on all sides, which is a treasure land of feng shui. In the past, King Wen of Zhou, who had Fengming Qishan, created the foundation of the Zhou Dynasty for 800 years, and then there was the Great Qin State of 'Yu Lie of the Sixth Emperor' to send a letter to Guguan to unify the world.

Xiang Yu's own reluctance to stay in Guanzhong does not mean that he does not attach importance to this place. He convened a meeting of princes and generals from all walks of life, and said proudly: "King Huai was supported by my uncle Xiang Liang, and there is no merit, so how can he preside over the agreement?" It is the generals from all walks of life and my Xiang Yu who fight the world! ”

As a result, he respected King Huai as the righteous emperor, and in fact no longer obeyed King Huai's orders.

In January 206 BC, Xiang Yu established himself as the overlord of Western Chu, ruled the nine counties of Liang and Chu, and built the capital Pengcheng; Liu Bang was named the king of Han, divided into Bashu and Hanzhong, and built the capital Nanzheng (Hanzhong, Shaanxi).

Xiang Yu divided the pass into three and gave it to the three generals of the Qin Dynasty: Zhang Han was the king of Yong, and the capital was ruined (Xingping, Shaanxi); Sima Xin was the king of Sai and built the capital of Liyang (Yanliang, Shaanxi); Dong Peng was the king of Zhai, and the capital was Gaonu (Yan'an, Shaanxi). The rest were crowned fourteen princes and kings.

Liu Bang's fiefdom was mountainous, with mountains to the east, mountains to the south, and plateaus to the west, and the only northern exit to the plain was where three Qin generals sat down. This is to trap Liu Bang alive! Liu Bang was a hundred unhappy in his heart, but the situation was stronger than others, so he could only swallow his anger and accept the reality.

If Xiang Yu's original plan was divided, Liu Bang would not even be able to get Hanzhong. Fan Zeng suggested that Xiang Yu drive Liu Bang to Bashu.

Zhang Liang transferred all the thousands of catties of gold that Liu Bang rewarded him to Xiang Bo, first, to thank Xiang Bo for helping Liu Bang at the Hongmen banquet, and secondly, to ask Xiang Bo to fight for Liu Bang's Hanzhong fief.

Take people's money and eliminate disasters for others. Xiang Bo said to Xiang Yu: "Liu Bang first attacked Guanzhong, and now he is only assigned to the land of Bashu, which is too unfair!" Give him Hanzhong County as well. ”

Hanzhong is between Bashu and Guanzhong, both belong to the mountainous area, which is not a good place. Xiang Yu gave his uncle face, and gave Hanzhong County to Liu Bang.

Zhang Liang was relieved, Hanzhong is the southern gate of the Guanzhong region, once the situation changes, and then go north to seize Guanzhong! Anything is possible.

After doing this, Zhang Liang had to say goodbye to Liu Bang and return to the side of Han Cheng, the king of Han. Although in Zhang's conscience, he has long believed that Liu Bang can become the overlord of the world. It's just that his father and grandparents have served as the state ministers of five generations of Han kings, and Zhang Liang is burdened with a heavy family mission.

Liu Bang understood Zhang Liang's choice, and he said sincerely: "Ovary, I understand. Don't worry, don't worry. Remember, no matter when, my Liu Bang's door is always open to you. ”

Liu Bang gave Zhang Liang a large amount of money, and after Zhang Liang accepted it, he gave it to Xiang Bo.

In April of the same year, the princes and kings of all walks of life held a strike ceremony and returned to their fiefs. Liu Bang led the people of his headquarters to Nanzheng, passing through Du County to the mountainous area of Hanzhong. After the army passed, they burned the plank road erected on the cliff, and told Xiang Yu that he had no ambition and was content with the territory of the feud.

Most of Liu Bang's subordinates were from Shandong (east of Yinshan) and missed their hometown. As the saying goes, it is difficult to go to Shu Road, and it is difficult to go to the sky! Bashan Shushui, inconvenient transportation, in the Qin Dynasty was a place of exile of prisoners. The morale of the army was low, and there were people who kept deserting on the way and said goodbye.

Liu Bang is also very depressed in his heart, and often borrows alcohol to kill his sorrows. The sky of life is gray again. How to change the status quo? Liu Bang is desperate to find an exit.

At this time, there was a person who entered Liu Bang's sight and finally changed everyone's fate.
