Lin Fan transmigrates into a high-martial urban world. Just to protect himself, he spends 9.9 yuan online on a copy of The Cosmic Primordial World Star-Devouring Art.
Following the customer service agent's advice, “Practice it if you want, or get lost,” he manages to practice it all wrong. While everyone else trains in martial arts, he trains his mouth, growing stronger simply by eating!
Eat a ton of steel, gain [Indestructible Vajra Body];
Swallow the waste leaked from a nuclear power plant, awaken [Thunder God's Physique];
Take a bite of an alien meteorite, and his body breaks through the atmosphere...
The world's strongest fighters panic: “Stop him! If we let him keep eating, he'll treat the entire solar system like a bag of snacks!”
Lin Fan happily gnaws on an asteroid, looking aggrieved: “Customer service said the cultivation art was fine. Is it really my fault that my teeth are too good?”
