Three Kingdoms: I Defected to Liu Bei, Old Cao, Why Are You Crying?

Qin Tian transmigrated to the Three Kingdoms era as a poor scholar. To change his fate, he sought knowledge everywhere and eventually joined Cao Cao's ranks. With his foresight beyond the times, he repeatedly achieved merits. He intended to help Cao Cao conquer the realm, but his great contributions aroused Cao Cao's suspicion. During the Battle of Wancheng, seeing that Old Cao was about to ruin everything, Qin Tian advised him again, only to be rebuked. So Qin Tian decisively resigned, thinking, You, Old Cao, are so suspicious? Then I won't be your strategist anymore! Thus, Qin Tian switched to Liu Bei's side and single-handedly altered the course of the world ahead of time. Seizing Huainan, battling Lü Bu, defeating Sun Ce, taking Jingzhou-within a few short years, he helped Old Liu achieve hegemony. Years later, an aged Cao Cao, lying on his sickbed, said to his attendants: "I have no regrets in my life, except for one thing-Qin Zixuan's departure. That was my fault!"
