Any Stories About Ghostly Energy Resurging and a World Where Everyone Tames Ghosts?

I've Recently Gotten into Ghost-Taming Stories!! Any Where the Protagonist Can Keep Making Ghost Contracts!?

Any Books About Making Contracts With Ghosts?

Looking for books similar to *You Were Supposed to Exorcise Ghosts, So Why Did You Make a Pact with the Entire Ghost Horde?*

Pets, Beast Taming, Contracts, System

Supernatural Entities Resurge, and the Protagonist Makes Contracts With Ghosts

Looking for horror or supernatural-revival stories where the male lead makes a contract with ghosts and monsters from the start, like Heibai Wuchang and the like...

Ghostly Energy Returns, Ghost Tamers, and an Invincible Lead

Stories About the Advent of the Strange

Looking for books similar to *The Weird Descend: I Became the Lord of the Weird*. I think it's pretty good, so you should give it a try.
