My Portable Grandpa Is My Future Self

Dongfang Chi thought that his life would only be boring monster fighting and leveling up, until one day, four self-proclaimed future selves came to live in his mind. Donghuang: "Dongfang Chi, open your eyes, I am Donghuang, and this time I brought two plans..." Black Death: "The occupied area is a place with tens of thousands of exotic beasts. There seem to be too many exotic beasts here!" Scientist: "I'm just a researcher, I don't have as much power as they do." Love Saint: "Dongfang Chi, believe me, you just want to give them a home, and you will never be beaten!"
