In a corner of the bustling Jiangcheng, there is an old bookstore called "Wangyouzhai". The owner, Ye Qingxuan, is a single father who barely makes ends meet with his five-year-old daughter. People only know that he is gentle and abject, but they do not know that he was once the supreme immortal emperor who controlled all realms and overlooked the era.
A long-planned betrayal made him reborn as a Taoist, and his soul turned into a dusty "Tao seed", sealed in a secular ancient book, and fell asleep in the city. Until his daughter's sudden illness made him in despair, he accidentally unlocked the dust-laden memories with a drop of blood.
However, what returns is not the overwhelming magic power, but the broken memory, incomplete Taoism, and the instinct of being a "father".
At the same time, the child's mother, who had disappeared for five years—the already dazzling international queen Lin Weiran—suddenly broke into the peaceful life of him and his daughter with an agreement and endless guilt.
When the parenting scriptures of the cultivating immortal emperors meet the elite education of modern science; when the dusty grievances and hatreds in the sea of stars collide with the glittering fame and fortune fair of the city.
Ye Qingxuan found that coaxing his daughter to sleep seemed much more difficult than fighting in the Star Sea. And the woman who once made his heart flutter seemed to have an unknown secret...
Holding the baby in his left hand and pinching the hand with his right hand, the former Immortal Emperor just wants to be a qualified nanny today.
"My daughter deserves all the beauty in this world. Whoever dares to touch her, I will let anyone... Enter reincarnation again."
