Three Kingdoms: I Switched to Liu Bei, Why are You Crying, Cao Cao?

Qin Zhen traveled through the Three Kingdoms period and became a scholar from a poor family.

In order to change his fate, he studied everywhere and finally joined Cao Cao's army.

With insights that transcended his time, he made numerous achievements.

He originally wanted to assist Cao Cao in achieving hegemony, but unexpectedly, his great achievements aroused Cao Cao's jealousy.

It happened to be the Battle of Wancheng. Seeing that Cao Cao was about to kill the three sages with one shot, Qin Zhen tried to persuade him again, but was annoyed by Cao Cao.

So Qin Zhen decisively resigned and left. "Aren't you, Cao, too suspicious? Then you might as well not be a military advisor!"

At this point, Qin Zhen joined Liu Bei's army and, with his own strength, changed the overall situation in the world ahead of time.

He captured Huainan, fought against Lu Bu, defeated Sun Ce, and took Jingzhou. In just a few years, he assisted Liu Bang in achieving his hegemony.

Many years later, Cao Cao was in his old age, and on his deathbed, he said to everyone:

"I have done nothing in my life without regrets, except for Qin Zixuan's departure, which was my fault!"
