Ruling the World, Starting as a Live-In Son-in-Law

Mo Yang transmigrates to an ancient world called the Great Feng Dynasty and is forced from the start by his stepmother to marry into another family in place of her son.

Worse, the bride is the daughter of a disgraced official whose family has been confiscated and exiled.

You want me to die in your son's place!

Mo Yang immediately cuts ties with them and uses his modern knowledge to rise to prominence.

Cement, gunpowder, steel, cannons...

By the time he reaches the pinnacle of his age,

his stepmother and his half-brother begin to regret it, coming to his door one after another to beg on their knees for his forgiveness.
