Live-In Son-in-Law: I Build Nuclear Weapons in Great Song

An explosion in the laboratory tears Lin Mo apart. When he opens his eyes, he has become a failed scholar in ancient times, scrubbing chamber pots in a brothel.

“Useless good-for-nothing! You can’t even scrub a toilet without falling into the cesspit!” a servant sneers, standing on the top scholar’s head.

A PhD from the National University of Defense Technology in his previous life, he clenches his fists.

Suddenly, a lavish carriage stops at the mouth of the stinking alley. From behind the curtain, a beautiful, icy-eyed woman fixes him with a blade-sharp gaze. “Get cleaned up and come to my room.”

Later, when the vast imperial merchant fleet commanded by the Su family’s young mistress sinks an enemy warship, the entire court finally learns that the useless man who scrubbed chamber pots has invented divine weapons capable of overturning the world.
