Every ancient building is a prison.
Chen Yuan, a young restorer of ancient buildings, discovered that the Buddha statues in Yungang Grottoes were "fading" in the year Bingwu. The dusty notes led him to a secret identity - a descendant of the "Tibetan Keeper". What he was forced to inherit was not a skill, but a seal that lasted for thousands of years: Why did the Hanging Temple fly? Why do the tenons of the wooden pagoda in Yingxian County unravel themselves? Behind the miracles of ancient architecture, ancestors used wood and stone as prisons to imprison "beings" that should not exist in the world.
Now, the prison door will open. Transnational forces covet the power of the seal, and the ancient prophecy is counting down. Chen Yuan must learn to let the Buddha "close his eyes" before the full moon of the Lantern Festival, and complete the last protection in the double gap between history and reality.
Wood and stone are silent, and the secret of heaven will be revealed.
