I Draw Blind Boxes in the World of Ghost Stories

A salty fish graduate student in the Department of History is forced to bind to the "Everything System", and randomly obtains a ridiculous ability for each mission - powerful abilities have funny limitations, but funny abilities can make a comeback in desperate situations - he travels between urban ghost stories and ancient secret realms to survive, and four completely different fates are stretched to the limit. In the end, he grows from a chess piece forced to do business to a chess player who rewrites the rules itself.
