I! Feeding a Fantasy World

The world mutated, spiritual energy revived, and countless people awakened their powers, but a picture popped up in Han Yu's head. He was surprised to find that this picture scroll turned out to be a small world. As long as things were put in, they could be allowed to reproduce and evolve, and eventually form a real civilization! Put in countless plants, the plants started to fight, and eventually a plant civilization evolved? Put animals in, and the animals begin to evolve and eventually become giant beasts? Han Yu was surprised to find that the world he raised had turned into advanced fantasy planes. A piece of black iron enters the small world, and is instantly developed into a treasure by the fantasy world; a piece of spiritual stone enters the small world, and is copied in batches in the blink of an eye, forming a mineral vein... When the earth had barely evolved for a few decades, Han Yu's small world had evolved for countless epochs, and behind him stood a group of top powers in the fantasy world.
