Weird Apocalypse, Starting with a Painted Leather Shirt

(The end of the world + ghosts + decisive killing + human race revival) When the blood moon comes, the strangeness revives. Only ghosts can defeat ghosts, and thus the ghost master is born. The ghost master can contract ghosts to fight. The stronger the contracted ghost, the stronger the ghost master will be. This book will only contain Chinese ghosts, some from folklore, and some from the author's imagination.
