Doomsday Dragon Court

A few centuries ago, an advanced civilization in the universe left a safe on Earth. A few centuries later, a group of greedy humans tried to steal the technology in the safe that surpassed their own civilization. In an unexpected experiment, the safe was opened in advance, and biochemical catastrophes came one after another. Humans were reduced from the top of the food chain to the rations of various mutated creatures! An ordinary young man, Qin Feng, unintentionally obtained the supreme cultivation technique, Dragon Transformation Secret. Coerced by the apocalypse, he could only stop killing by killing, and step by step embark on the road to becoming stronger.
