To understand the meaning on the silver piece, Zhu Bufan was not yet capable, and since he couldn't discern its meaning, Zhu Bufan no longer troubled himself with it, but his intuition told him that this silver piece inscribed with Ancient Chief Language was absolutely extraordinary.
Zhu Bufan tried a little bit and clearly felt that this thin silver piece was extremely tenacious. Zhu Bufan gradually increased force, and eventually he exerted as much strength as he could muster, but none of it could deform the silver piece at all, let alone damage it.
Zhu Bufan had never imagined that this silver piece could be so terrifying. Out of curiosity, Zhu Bufan tested it with scissors and candle flame, starting very carefully, but in the end, no matter how much force Zhu Bufan exerted or whatever methods he used, it couldn't be damaged in the slightest.
By now, Zhu Bufan was fully certain that this unremarkable silver piece was indeed a rare treasure.
