A peerless glass-type Imperial Green jade hidden inside a twenty-pound black stone. The jade had a surface as large as a washbasin, solid green with no impurities or cracks, radiating a mesmerizing glassy sheen. Valued at 100,000 yuan, it was described as a once-in-a-generation treasure and national-level rarity. Hidden beneath a thick deceptive black crust, only a few centimeters deep.
