My name is Lin Jianwu. I have a ancestral tradition of exorcising ghosts and I charge a fair fee.
It wasn't until the man covered in blood fell in front of my store that I realized that there was really a ghost in this world.
He woke up with amnesia, but he was pleasant to look at, but a little clingy.
I reluctantly accepted him as the "treasure of the store", after all, he looked so fierce that he flew away like a ghost.
Later I found out that there was a god living in his body.
And that god has been waiting for me for a thousand years.
