Lu Li, a computer science student, steps into his dorm room, where a gear component activates the “Mechanical Medicine Compass” System hidden in the Taiji-shaped red birthmark on his body. A thousand years of mechanical ingenuity collide with modern technology! A mechanical prodigy reinforces titanium alloys with mortise-and-tenon joints, a chemistry fanatic concocts a corrosive liquid that eats through metal and bone, and a medical student improves reagents with herbs, while Lu Li decodes code using the trigrams of the I Ching. The hidden family keys in the bloodlines of all four turn out to piece together the lost “Mechanical Medicine Divine Device” from the late Qing dynasty. When a steam engine powered by dried tangerine peel resonates with fluorescent code, the science and technology competition becomes the starting point for their revival of cutting-edge technology!
