I, Prince of Hell, Am an NPC and a Student. It's Too Difficult.

Yan Yuyan's goal in life (ghost life?) Is to be a perfect background - dozing off in class on time, finishing first in the cafeteria, and being able to slip away from club activities. However, the "classmates" around me are becoming more and more strange: the senior who is floating, the senior who only has the upper body, the roommate who always complains that "the reincarnation queue number plate has expired again"... The system bug finally broke out: the reincarnation team was completely paralyzed, the Forgotten River data overflowed and flooded the stadium, and the evil spirits began to riot because they could not be reincarnated! Yan Yuyan, who was forced to open his business, yawned and reluctantly took out his mobile phone (Android version of the Book of Life and Death APP) and began to troubleshoot the fault. But while tracing the source code, he accidentally discovered his shocking past life identity that was deliberately hidden by the system under his "Buddhist" appearance - the source of all chaos seemed to be closely related to him? At this time, the barrage frantically flooded the screen: "Lord of Hell, stop checking! Go back to the school... Ah no, the three worlds are going to be overthrown by you!" Yan Yuyan looked at the messed up campus, sighed, and made a cup of wolfberry and chrysanthemum tea: "Don't panic, it's not a big problem. I'll send an email to the counselor first to ask for leave... Well, I'll take another class."
