I Only Have Garbage, but You Only Lack Garbage

The most unreasonable thing has happened: the world of cultivation is going to die! The foundation of cultivation is the power of abandoned spirits. The power of abandoned spirits comes from ancient garbage. However, these ancient garbage will be exhausted within thirty years. At this time, a man from Earth appeared, a man who was extremely miserable on Earth. He had nothing and lived by picking up trash. In other words, he only has garbage. It can also be understood that only he has garbage. Moreover, his garbage is much better than those ancient garbage. As a result, he became the savior of the world of cultivation, cheating all the way, using the way of showing off with flashes of flowers and lightning, and finally became the king of the entire universe.
