Lu Jingming, a cultural relic restorer, traveled to a prosperous Qianlong era where gears and energy roared, and became a scavenger at the lowest level of the Ministry of Internal Affairs. In order to make a living, he was forced to use modern knowledge to form a team to participate in the steam Cuju competition, controlling a thousand-pound mechanism to fight among gear traps. However, behind the winning streak, he and the restorer Shen Qingxian who accidentally traveled together gradually discovered that this national carnival event was actually a bloody test to select craftsmen to restore the "illusion of civilization". Under the prosperity of gear meshing, billions of souls are being quietly squeezed out. They must use their hands to restore cultural relics, and make the most difficult choice between the eternal illusion of prosperity and the cruel historical reality - should they repair this beautiful cage, or smash it with their own hands?
