After hearing Tang Jun explain the origin of the coins, Huo Sining began to suspect them. She reached out discreetly to touch the camphorwood box, and upon closer inspection, she noticed something was off.
This item had been inspected by both Zhuang Xiangyang and Xie Daoyuan, yet after staring at it with her Heavenly Eye for a long time, she couldn't detect even a wisp of purple aura.
Though the item was vacuum packed, judging from its appearance, the two coins seemed to have been unearthed from a burial site. If exposed to air, they would easily oxidize, so Tang Jun was quite knowledgeable, and he had done his homework by specially commissioning a transparent vacuum box to preserve the coins according to their size.
Once the coins were sealed, they weren't meant to be taken out. If the box were to be opened, a new one would have to be made, which would be troublesome and could damage the coins.
