I'm a Cleaner. What's Wrong with Eating a Sun?

[No heroine + kills without mercy + exotic beasts never take human form + no saintly behavior + pure darkness] Ye Chi lived worse than a pig, tortured and exploited for ten years. At death’s door, the truth came out: he had been deceived! His parents were silenced in a car accident, and his younger sister was abused to death by the powerful! Those so-called promises were all lies! His hatred surged to the heavens, and he died with his eyes open! When he opened his eyes again, he had become a cleaner fish. [Abyssal Iron Stomach] A hundredfold digestion. He can devour mountains, seas, and everything under the sun. He can eat anything, with absolutely no side effects! [Sacred Source Spirit Body] Perfect conversion. Anything he eats can boost his spiritual energy, and one bite is stronger than ten! Toxic nuclear wastewater? Other creatures rot from a single touch? He guzzles it like soda and evolves three levels on the spot! High-voltage electric spear? Others are cooked by a single hit? He swallows it whole and unlocks the Law of Thunder right there! From a half-meter-long little fish, to a thunderous giant beast, then to the sky-shrouding Xu Kun... Devour, devour, devour, devour, devour! His body grows at a crazed pace, leaving humanity utterly dumbfounded! The world is shaken. Warships and fighter jets are deployed in full force, and he is branded a world-ending disaster. Ye Chi only smiles faintly, looking upon humanity as ants. He raises his eyes to the sun above. I’m just a cleaner fish. What’s wrong with eating the sun?
