Things Left Behind by Tang San

What met his eyes was a very large room, much like the Tang Sect Underground Headquarters. It was completely empty, with all the treasures hidden in secret compartments. Without prior knowledge, one might have assumed it was simply an empty room.

Chen An did not inspect them one by one. Instead, he went straight for the treasures that interested him more. The first hidden compartment he opened contained a stone shaped like a token. Calling it a stone token would be quite fitting.
