Lin Bei, a down-and-out young man who runs a street vendor at the stone gambling market on the border of Ruili, barely survives by selling "head covering materials" worth tens of yuan a piece. Until one day, a piece of jade scrap that accidentally broke cut his finger, and the blood soaked into the chalcedony. Lin Bei awakened to a pair of magical "jade eyes" that can see through the inside of the original stone - whether it is a hooded material or a semi-clear material, with a focused glance, he can see all the water, cracks, and roots.
