Shen Mo, a poor student at the Academy of Fine Arts, unexpectedly inherited an old painting gallery in the west of the city at the funeral of a strange aunt, along with a deposit of 120,000 yuan and a strange suicide note: none of the paintings in the museum can be sold, and the people in the paintings must not be looked at at midnight. Rival Lu Nianhao spends 6 million to fight for the art gallery, but there is a shocking conspiracy behind it. On the night of entering the art gallery, all the characters in the eleven ancient paintings came to life. Jiang Muci, a tailor from the Republic of China, walked out of the painting and told the truth: the demon Cang was sealed deep in the art gallery, and countless painting spirits were devoured by it for hundreds of years. Shen Mo is the only Lin family bloodline that can maintain the seal. The demon will use her hands to draw the door to resurrection on the seven-day full moon night, and massacre all sentient beings in the world. Lu Nianwei is pressing forward step by step with forged inheritance rights, the ancient fallen angel Lucifer has hidden ambitions, and his aunt and mother have left behind layers of plans. Holding a paintbrush that can tamper with all things, Shen Mo did not want to be reduced to a sacrifice, so he formed an alliance with a centuries-old painting spirit, used cinnabar and blood ink to create a reverse seal, and dealt with demons and ambitious people. When all the painting spirits died and were bound by the shackles of their blood, she used her own flesh and blood as a talisman to rewrite the world in the painting with her own hands, turning the cage into a refuge for all the dead souls.
