The old man explains that the universe is divided into four realms, and that one breath is a time limit, and one's inner strength is a measure of how strong one is. Each realm has a different amount of time, and each realm has its own set of rules. The fourth realm is called "saint's realm," and the essence of a scene is compared to its birth, its lower birth, and its above stars. The essence of the scene is likened to the birth of the grain, and the flow of the grains. The flow of heaven and earth is like saints. The world has no more saints, says the old man, and he begs him to help him. He says that if he wants to protect the heavenly disk, he will need to learn to use the qi .
