Douluo Continent: Twin Blue Silver Grass

After being reincarnated into another world, he found that he had turned into two intertwined blue silver grasses. Then... I was soaked by the rain, blown by the wind, and stepped on and peed by those animals. More than 50,000 years later, he finally turned into a human form. The first thing he did was pull out the teeth of all the descendants of animals that had stepped on him.
