Shinji Matou at Your Service - Chapter 8 -

The daughter of a duke, the stuttering Maximilian, married a knight of lowly status at her father’s coercion.

“I want to be a true demon.”

A boy not older than 20 years wished as he looked at the sky.

After suffering from the trauma for many years, he finally gave up on life.

People called him ugly, demon, and hideous.

He bared with it, but today he finally broke.

With a piercing pain in his chest, he died.

When opened his eyes, Logan found himself in another world and inside the body of a demon.

His wish was granted, but at what cost?

He had no power and was the lowest among the demons.

No one to help, no one to be with him.

But it did not affect Logan. Because he had something else with him.

‘Sin and Virtue System.’

Guiding him towards his goal to become a true Demon.

Logan’s conquest has begun, so be a part of it.

Otherwise, you will miss him.

The true Demon!

However, is the MC the 'only' one to have a system?

Hm?

Read the fucking novel and find out!

“Please, I implore you to save the world.” This is what a goddess in white says to me in a pure-white space. Such is the standard line that suggests the game is about to begin. Please say this stirring line to boys and girls with sparkling eyes! It’s wrong to direct it to someone like me, who’s exhausted from job hunting! When I declined her politely, she flew into a fit of tears; when I agreed to assist her on small tasks out of reflex, she proclaimed: “it’ll be fine if you just help in the Starting-Village Arc. Please guide the Hero!” Then she tossed me into another world. No, this is a world modeled after a game that this gamer goddess likes…

This is a story of the flesh pushing everything.

In the Great Ye Dynasty, darkness descends, full of evil spirits and ghosts, killing invisible.

In the face of demons and evils, ordinary people can only shiver, curl up in the corner, and wait for their lives to come to an end.

Jiang Dao came through, carrying a martial arts modification system, and any martial arts can be modified infinitely as long as he glances at it.

The mad magic stick method, the eagle claw iron cloth shirt, the poisonous sand palm, the violent ape magic… are all revised to the realm of a thousand years later.

Facing the evil spirits, Jiang Dao had a burly body, muscles all over his body, and his eyes were like electricity.

“Evil spirits? Who said martial arts can’t kill evil spirits?”
