Who Told This Lunatic to Cultivate Immortality?

Once he traveled through time, Yan Chuyi became a demon cultivator who could be punished by everyone in the world of immortality, and thus began his wanton and crazy path of cultivation. When you are in despair, people use force to fight against you; after success, people talk about etiquette and laws. There is no constant good or evil in the great road of heaven and earth. Gods and Buddhas have also stepped on the bones to become gods. All living beings have been killed in the past. Machiavellian schemes and ruthless fighting are the normal conditions of cultivating immortals. I am a demon and do whatever I want. Anyone who offends me will bear the consequences!
