Heaven-Defying Martial God, and You Call Him a Poor Scholar's Son?

After transmigrating to ancient times, Qin Yun obtains the Martial God System.

He can gain the Overlord's physique, master the military strategies of Guigu, learn the Sun family's art of war... With a flip of his hand, he can summon clouds and rain. None of it is beyond his reach!

But Qin Yun is dismayed to discover that he has to activate the System first!

And the activation condition is marrying a princess-level beauty!

A humble country lad, Qin Yun can only cry out in despair.

That is, until a duke inexplicably takes him in as a live-in son-in-law, finally activating the System.

He thought that from then on, a lie-flat life with a beautiful princess would be within easy reach.

But as he learns more, Qin Yun discovers that he is nothing more than a chess piece!

Qin Yun:

All I wanted was to lie flat as a live-in son-in-law. You people forced me to become a Martial God and flip the whole board!
