Ming Lan applied for a visa. Why didn't the monk cancel her visa?

In order to pave the way for the next story, Ming Lan asked the monk not to release her visa. Chapter 120 in the novel Know No tells that the old monk said that this brand was not Ming Lan's, and the monk didn't cancel it for her, which paved the way for the future plot, saying that the next brand was not the end of Ming Lan, suggesting that Ming Lan would have a better life than the brand said.
