[System from the start, lighthearted and funny, power fantasy, decisive and ruthless, both smart and brave, founding a sect, invincible and having a blast all the way!]
Our story begins when a young man named Mu Qingkong transmigrates to another world by accident, receives a mysterious System from a mysterious woman, and agrees to join forces with her for mutual benefit...
That year, an old demonic cultivator said he had extraordinary bones and talent, like a divine child descended from Heaven! A cultivation genius who came along only once in a thousand, or even ten thousand years! And he pretended to become the old man's disciple...
That year, standing before the greatest Daoist sage under Heaven, he shouted with domineering confidence: "I never went there, so consider me here. At this moment, I am the Tathagata of this world!"
That year, he challenged the end of the Sword Dao and said, "I hear you're Xuanyuan Wubian, the end of the human world's sword, known as the Sword's Final Destination? I want to give you a try!"
That year, he wiped out the Joy Hall of the Buddhist world's temples for her. When the second-greatest Buddha sage under Heaven pursued him, he stopped and said, "Running away is a pretty good option, but I'd much rather kill you!" And so on.
(The blurb doesn't do it justice, fellow Daoist. I'll be waiting for you in the story!)
