580 Discovery

"It seems like someone has been here before." Realizing that something was abnormal in the cave, Leonard and the other two quickly turned on their high-power flashlights and carried out a thorough inspection.

A few minutes later, Fairmont suddenly pointed at the wall facing them, claiming that there might be a hidden door. After careful observation, Leonard discovered that there might indeed be a hidden door on the wall.

This hidden door, which was exquisitely made back in the day, appeared no different from its surrounding environment. However, different rates of expansion due to age have affected both parts.

As a result, if one looks carefully now, they would see a faint crack forming on the wall, which exposes the hidden door beneath.

Once the target was discovered, they quickly started digging. The door may have been created by human hands, but it was blocked by a thick layer of rammed earth, possibly due to concerns about the difference in materials causing obvious defects.
