Mo Han, a geek in the mechanical and electrical department, accidentally obtained the remains of the retired industrial mecha "Anvil". Facing the "World College Student Mecha League" monopolized by capital teams, he led the technical geek Anya and the practical geek Lei Zhen to use 3D printed shape memory alloy joints to give the mecha the "fault self-healing" power, and created an original "defect utilization algorithm" - a hydraulic rod fracture? Just spray high-pressure oil mist to interfere! Bearings overheating? Instantly converted into a short blade of thermal energy! Amid ridicule and doubt, Mo Han resolutely open sourced the core blueprints, igniting a prairie fire of the "Open Source Mecha Alliance".
