The Supernatural Appeared from the Start, and I Somehow Became a Ghost Slayer

[The supernatural appears from the start, and somehow I'm terrifyingly powerful! Also known as "Lost in the Moonlight". No System, no mindless protagonist, nearly invincible, slower-paced, and not a traditional urban high-martial-arts story. Read with caution if that's not your thing.]

One day, Zhang Cheng discovered that he was being haunted by supernatural beings. They lingered around him, acting erratically.

Then, a sudden accident awakened a profession called the “Gravedigger.” This profession turned out to be the bane of vengeful spirits, so Zhang Cheng set off down the point of no return: training them into submission.

Dog-Headed Wraith: This guy's a monster! He hangs me up and beats me every single day!

Beautiful Female Ghost: He's a heartless jerk. He took my innocence and then tried to abandon me!

Headless Female Ghost: I've had it so rough! He actually forced me to do that kind of thing!

The vengeful spirit of a dead classmate: That's right, I can vouch for them. What they said is true.

“Damn it! I'm warning you, don't go spreading lies! I'll sue you for defamation!” Zhang Cheng cried out in protest.
