Lin Xiao, an ordinary student struggling to catch the last train of the "low-level martial arts era," has a good appearance but can only be a ruffian and invisible. A strange encounter reveals a mysterious "Martial Arts Modifier" in his mind!

Modify a technique's loopholes? A piece of cake! Improve your martial arts aptitude? Just a flick of the finger! Even... tamper with the rules of reality?

When the icy school beauty blushed and pleaded: "Lin Xiao, help me change my talent, I...I will agree to anything you say!";

When the cold and beautiful policewoman bit her lip and whispered: "Modify this clue, tonight... I'll listen to you!";

When the tycoon's daughter flirted with him: "Save my family, and I'll share my trillion-dollar fortune with you!"...

Lin Xiao thought his life would be a success, a land of beauties and kingdoms. However, when he attempted to modify his realm and touched a forbidden area, a terrifying alien pursuer tore through space and emerged!

At that moment he realized that what he had modified was not a cold law, but a dormant supreme being that was powerful enough to subvert the universe - the "source code"!
