Game designer Chen Buji transmigrates to a world of advanced martial arts, with no System and no wise old mentor.
He can sense the world's corrupted underlying rules. When he gets hit, he alters how force is transferred; when he falls off a cliff, he adjusts gravity; when he is gravely injured, he can tamper with the logic of life.
While others train bitterly and risk their lives, he goes around repairing flaws in the natural order.
The five great sects vie to recruit him, while an ancient corruption sees him as a thorn in its side.
As he fixes more and more flaws, the truth behind the ancient gods' deaths five hundred million years ago and the collapse of their seals slowly comes to light.
Once he has mastered physics, life, space, time, and causality, he finally understands: he is the biggest BUG in this world.
