Overworked office worker Lu Chuan accidentally transmigrated into a cute golden British shorthair cat and bound with the Devouring Evolution System! Originally wanting to eat and lie flat in peace, he accidentally stumbled into being contracted by the reborn Empress Luo Lingwei. The Empress, who originally wanted to contract a divine beast to counterattack and become an immortal, unexpectedly gained a divine cat that can infinitely evolve. One person and one cat start a wonderful beast-taming journey. Lu Chuan relies on devouring all things to advance all the way, and Luo Lingwei carries the divine cat to grow steadily. Without disputes or grudges, there is only a relaxed and interesting beast-taming daily life, jointly heading towards their wonderful cultivation path.
