In 206 BC, the tyrannical Qin regime fell apart under the attack of Liu Bang and Xiang Yu's anti-Qin righteous army. With his absolute military strength, Xiang Yu drove Liu Bang, who had entered Guanzhong Xianyang first, back to Bashang, and took advantage of the fact that King Huai of Chu was stationed in Pengcheng and had no time to divide the world, and came to Pengcheng to return to his army. Seeing the beautiful love between Xiang Yu and Yu Ji, Lu Zhi, who was held hostage, was jealous and had evil intentions. King Huai's desire for the beautiful Yu Ji was his unforgettable extravagant wish. Although Xiang Yu had no room to make his words count by using his army to command the princes, King Huai was still obsessed with marrying Yu Ji. After returning to Pengcheng, Xiang Yu's request to meet King Huai was declined by King Huai on the grounds of illness. In order to remove the stumbling block that hindered his unification of the world, Xiang Yu listened to Fan Zeng's advice and asked Yu Ji to visit King Huai in the palace to find out the truth. He also lied to Yu Ziqi that Yu Ji could not bear the frequent wars and the life of displacement, and wanted to marry King Huai. When King Huai left the Pengcheng Palace and went to the new capital of Chen County, when he realized that marrying Yu Ji was fake and expelling him from Pengcheng was true, what awaited him was the death date set by Xiang Yu. After the stumbling block of King Huai was removed, Xiang Yu married his beloved woman Yu Ji in Pengcheng with the most solemn etiquette. In order to provoke the relationship between Yu Ji and Xiang Yu, Lu Zhi told Yu Ji the truth, so that Xiang Yu was "rejected" by Yu Ji on the wedding night. After the wedding, Xiang Yu led his army to the war, leaving Lu Zhi an opportunity to frame Yu Ji. As soon as Xiang Yu left, Yu Ji became ill due to worry and could not get up. Upon learning that Yu Ji was ill, Lü Zhi came to visit her and gave Yu Ji the poison that harmed the fetus as a good medicine for the disease. When the maid found out, it was too late. At this time, Shen Qishi secretly helped and expelled Yu Ji from Pengcheng while there were only a few Chu troops left in Pengcheng. When the news reached Xiang Yu's ears, Xiang Yu ordered Long Ju to stay in Chengyang to continue to deal with Tian Guang and Tian Heng. He and Ji Bu led only 30,000 followers to return to Pengcheng. The soldiers stationed in Pengcheng were originally the remnants of the Chu State. When they saw Xiang Yu leading his army to kill, they turned against him and joined Xiang Yu. Xiang Yu was annoyed by the expulsion of Pengcheng, but he could not save Yu Ji from the fate of being unable to have children. At this time, Liu Bang gradually took control of the battlefield with the help of Han Xin and Chen Ping. In the battle of Gaomi, after Long Ju's army was completely destroyed in Han Xin's formation, Xiang Yu was forced by Liu Bang to negotiate peace. Across the wide Guangwu River, Xiang Yu and Liu Bang reached an alliance of "Chu River and Han River". Just as Xiang Yu was returning to Pengcheng with his army, Liu Bang attacked from behind. Besieged at Gaixia, Xiang Yu, the former god of war, no longer had the domineering spirit of the past. Depression and helplessness attacked Xiang Yu together. In drunkenness, Xiang Yu was filled with sorrow. He sang a swan song "My strength is as great as the mountains and my spirit is as great as the world. The time is not right and my horse will not go away. What can I do if my horse will not go away? Yu Xi, Yu Xi, what can I do?", which made Yu Ji, who was infatuated with him, perform a scene of "Farewell My Concubine". "The Han soldiers have occupied the land, and the sound of Chu songs is heard everywhere. The king is exhausted, and what can I do for my humble concubine..." After the song, the peerless beauty Yu Ji ended her short life in the arms of her beloved man.
