However, when Zhou Chun opened those jade boxes with anticipation, he was quickly disappointed.
Possibly because too much time had passed, the various Spiritual Medicines that were stored inside the jade boxes had all withered away, losing all their potency and becoming useless.
Out of twenty or thirty jade boxes, there were only two things that were useful.
One of them was a palm-sized pentagonal token, which Zhou Chun recognized very well. It was the "Heavenly Spirit Order" that he had seen before at the underground auction, and it was also a Class C token that could be used.
The other was a silver-white metallic foil piece resembling a Dragon Scale, inscribed with complex and mysterious runes.
The use of the "Heavenly Spirit Order" did not need to be explained, Zhou Chun already knew of its purpose.
The silver-white metallic foil piece, he had also seen records of such an item in the classics.
