Lin Zhou, a "memory keeper" who silently restores old objects in corners of the city, has his life completely overturned by a mysterious package engraved with the symbol of ouroboros. The package is not an antique, but a miniature ancient city called "Yingzhou" - the pavilions, the people in the market, and even the raindrops are all real, but they are trapped in a transparent barrier and are on the verge of decay. When he saved the entire city with a drop of water, the men in black robes on the city tower knelt down and worshiped him from afar, regarding him as the "god of the sky."
As sandalwood ash gives the world warmth, and ancient city wall brick powder strengthens the boundary wall to resist the void, Lin Zhou discovers that this is no ordinary miniature model, but a "conceptual world" that has been stripped from mythology. Yingzhou, Fanghu, and Penglai, the three fairy mountains turned into isolated islands floating in the void, and the old objects he collected - original silk road silk from the Han Dynasty, palace silver needles, and fragments of ancient books turned out to be "conceptual materials" for repairing the world. When he connected the square pot with the galaxy, he revealed the terrifying truth about the "World Devourer": the Fairy Mountain was originally an ark imprisoned by the Ouroboros, and what he took over was the ultimate commission to save civilization. From repairing old things to repairing the world, Lin Zhou must light up the lights of Penglai in the void, uncover the secret of the sacrifice of the star-robed people, and fight against the darkness that devours everything... The miniature fairyland in his palm hides a mythical epic that subverts reality.
