Is It Impossible to Become an Immortal Without a Serious Illness?

Those who cultivate immortality must go against heaven. When Zhou Xun was seven years old, he believed that one day he would be able to enter the path of immortality. However, he practiced hard, studied ancient books, and tried various methods, but he still couldn't get started. It wasn't until he was seventeen years old that a sudden high fever allowed him to finally open the door to cultivating immortality. The doctor said: "It's the flu." Zhou Xun thinks: "This is spiritual energy entering the body, quenching the body and washing the marrow." As for fever-reducing medicine? "That is a forbidden poison that will destroy the monk's foundation."
