I Rewrite the Rules in the Ghost Stories

One day, Lin Ye, an ordinary overworked office worker, woke up to find himself pulled into an infinite-flow world called "Abyss Game." Every player was fighting desperately to clear instances, kill monsters, and earn points just to stay alive. But Lin Ye's System had a bug: he couldn't become a player. Instead, he could only randomly become an NPC in each instance.

Even stranger, he discovered that he seemed to be able to... alter the rules of the instances.
