Transform the Mortal World

I was brought back to the mortal world by a mysterious force and asked to reform myself. However, there is no trace of immortality in the mortal world, not even a dojo. Since we can't return to the fairy world, we can only transform the mortal world. "So the Earth Spirit Stone can expand the territory of a state? I actually have hundreds more." "We don't have enough manpower. We have to recruit volunteers to plant trees." "Father, I don't want to go back. I want to stay here and plant trees. Please help my daughter." The great religious saint prayed. After the local spirit stone expanded to hundreds of states, it was actually linked to another mortal world? After decades, no one wants to become an immortal anymore? "No, let me go back. I want to return to the mortal world to further my studies." The big guys in the fairy world protested.
