Mechanical Origin

This is a mechanical journey to another world where a young auto mechanic carries a mechanic system. However, unlike other predecessors who carry systems, Mu Yu's system is actually a scheming, naughty and irresponsible loli girl! "Want to learn about machinery? Go look up the books yourself! Want to learn mechanics? Go learn it yourself! Want to make machinery? Go and do it yourself! Don't have the materials? Find them yourself! What? You say I'm irresponsible? I'm here to train you!" ----[System, Lan Qi]
