Lu Zhou woke up and became the most powerful and oldest demon master in the world, with nine evil disciples who were full of evil and feared by the world. The eldest disciple, the leader of the Netherworld Sect, had thousands of demons under his command, and the second disciple, the Sword Demon, started killing people at the slightest disagreement. Without his cultivation, how could he discipline these evil disciples? The eldest disciple Yu Zhenghai said: "I have been invincible in my life. Except for Master, no one can ride on my head." The seventh disciple Si Wuya said: "We can't sleep or eat well until Master dies."
