Chen Rui, a gamer from earth, is reborn in a human body in another world, falling into the legendary, evil, brutal Demon Realm, inhabited by Devils called Mozu and where humans are treated as food. He has to survive while facing horrifying devils, poison dragons, and a variety of powerful enemies by using on a strange Super System chip and his wits, surrounded by the Devil’s beauties such as the black-bellied lolita princess, the iceberg queen, the violent scythe, and the charming succubus.

Wanting to live in the Devil’s world is hard! Wanting to live in the Devil’s world as a human is harder! Wanting a human to be the devil’s son-in-law is hardest!

Let us see how a small otaku uses his power and strategy step by step starting from an ordinary human to writing the legend as the devil’s greatest son-in-law.

This is the story of a crazy lich who possesses an internal game system and brings catastrophe to the entire world.

“Let’s look at the daily quests today… it’s the damned choose one-of-two-options-type again. Destroy a town with a population of 30,000 people or above; reward: 10,000 evil points. Steal lollipops from 3 children; reward: 1 evil point. If neither of the quests is completed, then 2 points will be deducted.”

“Tsk! You think I’m s*upid? If I really destroyed a town, a crusade of Epic-ranked Holy Knights would definitely come hunting me down. Even if I earned the points, there wouldn’t be any life left in me to spend them. I better just go be a kindly lollipop bandit.”

I’ve already had enough of being a notorious lich. Who says that a lich can’t be a good person? I’m definitely going to beat this damned system and be an upright and dignified good man.

Honor? Who needs that… Hmmm… that guy seems too powerful for me to take on now… I better keep a low profile for now.

You want me to help you? What do I get out of it? Nothing? Bye.

Hmm… that guy looks like he might cause me problems in the future. Better kill him before he becomes a problem…
