He was supposed to be nobody. Born with crippled spiritual roots in the weakest corner of the Mortal Heaven Continent, he spent his early years mocked by peers, dismissed by elders, and written off as a waste of a bloodline. The world had a plan for people like him — obscurity, mediocrity, a quiet death at the bottom of the cultivation ladder. Then the System arrived. Rude, chaotic, and absolutely unhinged, the Infinite Chaos System begins issuing missions so absurd they border on cosmic comedy — slap an arrogant Young Master, steal from a forbidden ruin, insult a Heavenly Lord to his face. And somehow, at the end of every ridiculous task, he walks away stronger than before. What begins as a shameless scramble for survival slowly reveals something far more terrifying. His talent isn't crippled. It was sealed. His bloodline isn't ordinary. It was buried. And the System that appears to be helping him? It was never designed to help anyone. As he rises from a forgotten boy in a forgotten kingdom to a figure that shakes the foundations of all Nine Realms — and the ancient dimensions lurking beyond them — the truth peels back in layers. The history of the cosmos is a lie. The gods who rule from their thrones are terrified. The first user of his System already conquered everything and nearly destroyed it all. And somewhere at the end of every road, a question waits: what do you do when you've beaten every enemy, unraveled every secret, and the universe itself asks you to become its next ruler? He laughs, pockets another ancient treasure, and causes more problems.

Yu Liang has only one goal which is to get out of the systems world, but so far, he hasn't found an opportunity to get out even though he is the hardest working of the system users. Until the God Lord who manages the system worlds gave him a unique task that would be Yu Liang's great opportunity to get out of this prison called the system of souls and reincarnations. Of course, Lord God's mission couldn't be simple, but the purification of the Dark BL System, which meant that Yu Liang had to fight dirty characters, protagonists or too innocent or too questionable character, getting to be criminals at times, insane villains and disgusting plots that could be considered crimes in many healthy countries. Thanks to Xiao Yao, the custom system given to Yu Liang, they have to take down malicious and toxic plots, deal with murderous villains, and make the protagonist shine in the world to purify the dark plot. Of course, the biggest problem is that every time the protagonist falls in love with Yu Liang, it is impossible for Yu Liang to keep his heart from the protagonist's continuous and persistently sweet assault. In the end, will Yu Liang make it out of the system world?
