What does it mean to tell fortune at noon _ die at noon?

Is there any other connotation in the dialogue between Bodhisattva and Wukong? Bodhisattva: Can I teach you the skills of seeking immortals, asking divination and exorcising evil spirits? The Monkey King:

The meaning is still obvious. For people, divination, chanting and meditation are all fleeting, passing away, and people return to the loess after death. Therefore, the most important thing for people is eternal life.

What do people think before they die, asking for immortality, chanting Buddha and meditating? No, people only know that they only want the end of their lives. This dialogue is about the ultimate meaning of human life.
