Spirit Exorcist

In his previous life, Q had learned some basic martial arts, but he tragically died of cancer while in college.

He transmigrates to a world of ghosts and monsters, with no parents, a house and money, and a famous idol for a younger sister who isn't related to him by blood.

By day, he is the sleazy "An Lun Yiye." By night, he is a killer and exorcist who roams the darkness.

With the System at his side, the world is his to command. Armed with a long spear and a central blade, he slaughters ghosts and monsters.

...Shh, be quiet. They're watching you.

(Just treat it as a light, easy read.)
