American Warehouse Taobao King

The protagonist, Yang Yong, gets into a fight at a bar and has his left skull smashed. The resulting intracranial hemorrhage compresses the optic nerve of his left eye, leading to a mutated special ability: he can observe the spectrum emitted by various metals. Every day in America, thousands of abandoned warehouses are auctioned off. Yang Yong, leveraging the special ability of his left eye, finds valuable items from the trash, such as gold coins, cars, antiques, firearms, and all sorts of miscellaneous items.
