Netherworld Investigator - Chapter 9

A hundred thousand years ago, there was a great war between cultivators. Immortals fell by the tens of thousands, the path of cultivation itself was severed, and after the dust settled, tombs forested the world.

A hundred thousand years after the last legend faded, Lu Yun, commandant of tomb raiders, descends upon the world. Armed with the Book of Life and Death, he has some burning questions to answer.

……

“This isn’t how you raid a tomb!” Lu Yun smirked at the cultivators frantically scurrying about the ancient tomb. “Do you want me to teach you?”

……

But ah, can someone teach him how to cure his new body’s erectile dysfunction?

What the heck? She, a famous doctor from the 23rd century, turned into a village peasant girl of a different world!

The little handsome son-in-law passed through a world as waste material and the husband of a wealthy family. But because of his lacking aptitude, the wealthy family had driven him out. So he worked hard and found a more powerful family’s thighs to hold onto. Soon enough, he became the strongest son-in-law and husband in history.

In this world, it was impossible to practice martial arts. It was futile so he might as well take advantage of his wife’s thighs and maintain a comfortable and leisure lifestyle.

He’ll train his wife to become the strongest and best person in the world.

“Whoever dares to provoke me, let my wife kill you!”
