The Three Kingdoms: General Yu She, reincarnated a hundred times.

Han Fu: "I have the unparalleled general Pan Feng, who can slay Hua Xiong!" Yuan Shu: "Wait, why do you need an unparalleled general to slay Hua Xiong? I have the junior general Yu She, who can easily take him down." Yu She: "..." This was the second time he'd experienced this. He'd realized that even without volunteering, Yuan Shu insisted he slay Hua Xiong. He just didn't understand—was slaying Hua Xiong some kind of good thing? Why was his lord so eager to take him? Yu She sighed helplessly and stepped forward with his head held high! "This subordinate obeys the order. I swear I will not return until I have slain Hua Xiong!" He left the tent, spear in hand, and the assembled lords heard a great roar of drums and shouts outside the pass, as if the heavens and earth were collapsing. They were all startled. Just as they were about to inquire, a junior general reported. "Report! Before even a single exchange! Yu She has already surrendered to Hua Xiong!"... His name was Yu She. In his first life, he volunteered and was killed by Hua Xiong, only to be reborn as Hua Xiong. He then surrendered to Hua Xiong, was killed by Guan Yu, and was reborn again, thus escaping Hua Xiong's fate. However, he was killed by Lü Bu and was reborn once more, only to surrender to Lü Bu. He fled to Chang'an and was then pursued by the allied forces of the warlords. In his fifth life, after much agonizing reflection, he joined Yuan Shu and was sent to supervise Sun Jian's attack on Jingzhou... He followed Dong Zhuo, but Dong Zhuo was assassinated; he followed Lü Bu, but Lü Bu was defeated; he followed Xiliang, but Li Jue and Guo Si fought amongst themselves. He was loyal to Yuan Shu, but Yuan Shu declared himself emperor; he joined Liu Bei, but was forced into a life of wandering; he fled to Yuan Shao, but suffered a crushing defeat at Guandu; he surrendered to Cao Cao, but was caught in the fire at Chibi! In this life, having experienced death after death, Yu She finally understood one truth: Now that the Han Dynasty is in decline, the warlords are not worth consulting. Who but me can save the world and the people? The glory of the Han dynasty has faded, and I will restore it!
