In this chapter, we learn that the crimson blood pill can restore the essence of a demon lord in ten breaths. This means that if you eat the pill every day for a year, you will have to eat the pills for ten years. If you want to practice immortality, you need to use the pill for a long period of time. This is why the master says that he will give you the pill back in a year. He also says that the secret treasure cave has a magical pearl bush that can protect the people from the evil spirit of the earth. The master then tells us that the other use for the magic pearl bush is to protect people from evil spirits. He says that if he uses the pearl bush for one year, he will take his 36 million credits and then he will exchange it for the five hundred million credits he needs to practice immortalism.
