In this chapter, we learn that the idea of a waterfall of life was first proposed by yisheng, a former great death, and later by the first living gods. The idea is that if you enter the waterfall, your soul will be recognized by the waterfall. If you want to be a god, you have to enter through the waterfall first, and that's why so many people have died trying to do so. The only problem is that the world is made up mostly of ordinary people, so it's hard for the living gods to save people who are guilty of killing them.
