I'm Really Not a Big Shot, I'm Just Passing By

Jiang Ye just wants to be an ordinary college student, go to class, play games, and skip classes occasionally. Until one night, he "passed by" a supernatural event in the teaching building, and ended up being bound by a thing that called itself the "Passing By System". The system says: As long as you pretend to be passing by and watch in a low-key manner, you will become stronger. Jiang Ye said: OK, what I'm best at is passing by. So—— Others thought he was just a passer-by, but he was like a boss with just one operation. Others thought he was a waste, but he accidentally pressed the genius to the ground and rubbed it. Others thought he was just here to make trouble, but under everyone's shocked eyes, he "incidentally" solved a world-class crisis. A superpower? He passed by. A rift in another world? He passed by. The Alliance of Travelers? He passed by. A cross-world war? He still passed by. Everyone is guessing: Who is this mysterious "passerby"? Jiang Ye looked innocent: I really was just passing by, do you believe it?
