I recommend the following books: "The Beginning of the Transformation of Infinite Followers into Elves": A 6V-level Leolu who cultivated in an egg was born, and it began to mutate. "Peak of Evolution": The loser protagonist, Li Fei, activated the human body evolution system. A group of evolvers gathered around him and fought non-stop with the mutated beasts hidden among the humans. It was a mutated beast battle style. [Devouring System's Infinite Evolution: Reincarnate as a mutated beast, bring along the devouring system, devour and evolve crazily, and become an invincible mutated beast.] [Reborn as a Pig, Invincibility Is All Due to Eating]: Become a pig after rebirth. When in despair, it will be bound to the infinite evolution system and become a mutated beast that looks down on the heavens. "My Unlimited Monster Clone": The story of the protagonist leading the humans on Earth to beat up the beasts on the Beast Planet. [Unlimited Enhancement of Monsters: The story of contracting a mutated beast, nurturing it, and evolving it to the highest form.] The above is my personal recommendation. I sincerely hope you like it ~
