Yun Chen, an ancient immortal who has practiced for tens of billions of years, successfully came out of seclusion and found that the former Tianyuan world had been split into ten realms. He casually accepted a disciple and became the Emperor of Heaven, and inspired the water snake to become the Dragon Ancestor. Tired of being invincible, he originally wanted to be free from the mortal world, but was accidentally bound to the system and became the honorary elder of Qingyun Sect. I thought I was retiring, but the remnants of the vampire clan came back with a vengeance. In order to protect the Taoism and the common people created by his former disciples, this invincible immortal who arrived late as a "pendant" had to pick up the sword again and train his disciples at the same time.
