Computer science major Lu Li stepped into the dormitory, and a gear part activated the "Mechanical Medicine Compass" system in Tai Chi Red Moles - a thousand-year-old mechanism and modern technology collide here! Mechanical geniuses use mortise and tenon joints to strengthen titanium alloys, chemical madmen prepare gold-eating bone-eating fluids, medical students use herbal medicine to improve reagents, and he uses Zhouyi hexagrams to decode codes. The family keys hidden in the blood of the four people actually pieced together the "Magical Medicine Machine" that was lost in the late Qing Dynasty. When the steam engine driven by tangerine peel resonates with the fluorescent code, the venue of the Science and Technology Innovation Competition will become the starting point for them to restart black technology!
