Xie Qingyao, who was once the Nine Heavens Immortal, was in charge of Hongmeng's luck, but when he was trying to reach the Supreme Realm of the Great Dao, he was betrayed by his close friends and Taoist companions. When his soul was shattered, he took the remnant soul of his native Immortal Palace and accidentally passed through his soul to a cowardly high school student with the same name in the modern city. Just on the eve of the end of the world, spiritual energy recovery is beginning to take shape. The former immortal has been reduced to an ant in the mortal world, but unexpectedly reunites with the white moonlight that haunted him in his previous life and died to save him - Su Rongyue. In this life, he lost his aloofness and restrained his supreme immortal power. He just wanted to protect her in the palm of his hand and block the wind and rain in the world. He used immortal magic to blend into the modern world, and used his remaining soul to refine his body. In the wave of the apocalypse and the revival of spiritual energy, he worked step by step to reach the top again, just to tell her: "I failed you in the past life, and I promise you a stable life in this life; if there is an enemy, I will pave the way for you with my immortal bones and escort you with my immortal blood."
