Chapter 55: The Key to Open the Treasure Vault

The huge boulder was about the height of a person. Because it was blocked by many weapon racks, its size could not be seen. It was pitch-black, but its surface emitted a grayish-white luster.

With just a glance, Lin Ran confirmed that this boulder was the same thing as the material on Mount Sword.

Daoist Li had once told Lin Ran that Mount Sword was formed by a very special mineral.

Not only could this mineral nurture the sword intent in the divine weapon, but it could also form a natural barrier and keep these sword intents within the mountain range. That was why the outside world did not know much about the situation of Mount Sword.

The appearance of the boulder here explained why Lin Ran could not sense any sword intent previously.

While he was thinking, Lin Ran had already arrived in front of the huge boulder.
