Supernatural: I have a small world

Sun Cheng traveled to a special world made up of countless supernatural and ghost films.
He found that there was an extra world in his body
The small world can devour everything and evolve continuously, and feed back itself
Plant countless grains, sell them to the common people at a low price, and earn hundreds of millions of merits
Planted countless medicinal materials, gradually monopolized, and became the largest supplier of medicinal materials in the world of spiritual practice
Seeing that your country is not happy, I will devour your mines and fertile fields, and evolve hundreds of millions of miles of mountains and rivers in my body
Gradually, Sun Cheng discovered that he had become the biggest boss behind the scenes in this supernatural world full of ghosts and gods.
Ever since, some new ideas came out...
