This Teacher Is Dark Through and Through

My name is Shen Mo, and I'm a history teacher.

My students think I'm gentle and refined. My colleagues think I avoid conflict and don't compete with anyone.

That was until I excavated an ancient tomb and discovered the secret of cultivators hidden in this world.

I want to cultivate.

So I need a stepping stone, for example, becoming the Li family's live-in son-in-law.

I know the Li family's heiress wants to use me to fend off a political marriage arranged by her family. I also know the Li family wants me to be an obedient ornament.

But what they don't know is this:

The son-in-law they treat as a pawn actually wants to carry off the entire chessboard.

I teach history in the classroom, and I'm writing history myself.

Don't test my limits. Even I don't know where they are.
