I recommend Immortal Martial Arts: Living in the Mortal World as a Clone, Demon Beast Devouring and Evolving to you ~ The main character of this book is a snapping turtle. After being bought, it becomes the main character's clone. It can devour demon beasts to fuse with its bloodline and obtain talent and evolution. When the clone evolved, the main body could obtain a large number of attributes and share the bloodline talent of the clone. From then on, his main body developed in the mortal world while his clone slaughtered in the Demon Realm, crazily devouring and evolving. The above is my personal recommendation. I sincerely hope you like it, meow~
