Mo Yuan, Earth's only immortal, falls into a deep slumber once every 600 years, sleeping for 60 years each time. After awakening this time, he returns to the modern city only to discover that someone has occupied his former home. He forcefully humiliates his enemies and kills his opponents with a single strike, revealing his former identity and causing old acquaintances to kneel before him. His sworn son, Ye Wuhen, is the invincible master of the Hall of Eternal Life, while his maid, Shen Qingqiu, controls the most powerful financial conglomerate of the age. His close friend Qinglong ranks third in the Dragon Group's hierarchy. Amid repeated assassination attempts, Mo Yuan returns to Tianfu Manor and reorganizes the forces under his command. However, he discovers that his sworn son Ye Wuhen and his maid Shen Qingqiu have joined forces to betray him, setting up an unparalleled deadly poison formation to seize the secret of his immortality. Their conspiracy ultimately reveals that immortality no longer exists anywhere on Earth.
