After making sure that everyone else had left, Leonard Ethan and Joan started digging immediately. Since there were no other people around now, they could fully utilize their extraordinary physical strength.
Within just one day, Leonard and Joan had successfully cleared away all the 5-7cm of sand and dirt on top, revealing what lay beneath.
Underneath the sand was a layer of wood material similar to the one they saw earlier on the door. However, due to having been buried for several decades, the wood had completely rotted and carbonized.
After easily shoveling away the thoroughly decayed wood, they finally saw the items that had been hidden beneath.
With the help of a high-power flashlight, Leonard and Joan could see the items at the bottom of the pit very clearly. At this moment, both of them showed expressions of astonishment.
