How Can I Improve My Cultivation When I Keep Being Reborn?

Chen Fuyao, a low-level monk, was forced to marry by a seductive demon cultivator and died. He was reborn as a madman. He wanted to prove that he was not a madman, but he saw things that ordinary people could not see. His stepmother went crazy before her death and made him hit by a car again. It was the third life when he opened his eyes again. When he woke up this time, he did not want to die again in this life, fell into the demon cultivator, and walked at night with hundreds of ghosts! We must live on even if we are neither humans nor ghosts!
