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?”
