You Asked Me to Fix Scrap, So Why Am I Building Mechs to Save People?

Lin Yan, the owner of a scrap yard with three million in debt, is forced to livestream himself making a lifting device out of junk. When a warehouse suddenly collapses, he cobbles together a powered exoskeleton from a washing machine motor and a scrapped frame, rescuing seventeen people from the rubble, only to face a shutdown and investigation. With fifteen days to pass inspection, predatory investors closing in, and the mystery of the accident his father left behind, he must turn a pile of scrap into technology that can truly change ordinary people's lives.
