The "Immortal Sword Master" Su Chen, who once climbed to the top of the immortal path and overlooked all the worlds, had his foundation destroyed and his soul broken due to a forbidden war that spread across the heavens. He took his only blood daughter "Nian Nian" to live in seclusion in a mortal city and opened a second-hand bookstore called "Wangyu Study". He just wanted to be a mortal and spend the rest of his life.
He thought he would seal the past forever, until he discovered that his five-year-old daughter's scribbling notebook had the terrifying ability to follow her words and draw things into reality.
Nian Nian draws a lamp, and in the long night a lonely soul comes to beg for light.
Niannian drew a door, and behind the door was connected to the lost ruins of the ancient god.
Nian Nian drew a friend who did not exist. The next day, a mysterious girl covered in bruises and claiming to be from the "future" knocked on the door of the bookstore.
This graffiti book is both the supreme treasure and the most terrifying taboo. It does not provide tasks or rewards, it just turns a child's most innocent fantasy into the most indescribable weirdness and miracle in reality.
In order to protect his daughter's unbridled imagination from being distorted and exploited, and to protect this small world that he wanted to spend the rest of his life guarding, Su Chen had to pick up his dusty power again and use his mortal body to deal with the various gods, demons and monsters who came after hearing the news.
He is the guardian of his daughter, the keeper of forbidden objects, and the... Terminator of all uninvited guests.
