A modern young man transmigrates into the chaotic Three Kingdoms era. Unlike other transmigrators, he has no grand ambitions to become a powerful lord or even unite the realm.
All he wants is to stay alive amid the turmoil. Fortunately, he has landed in Cao Cao's camp, right at the beginning of Cao Cao's rise.
But he doesn't much like Cao Cao, for one simple reason: Cao Cao is far too suspicious. He could have the young man killed at any moment.
He chooses Cao Ang, and since the two are close in age, Cao Ang comes to trust him completely after being talked around by him. He is Long Zheng, the Carefree Marquis of Cao Wei.
It's pretty good, I hope you like it.
Aside from the typos, everything else seems fine. I'll take another look later. 👀
