The concave-convex contest is like a game of raising worms, like a cocoon that tightly wraps the contestants one by one, making it airtight.
And if you want to survive, you can only kill.
The main character here is Jia Jin. The plot will be changed as needed. Newcomers, please support me. Also, the setting is Jin x Garderos. Black Gold and Gold are two souls that cannot merge. Black Gold likes Gold very much.
