What surprised him was that this treasure wasn't devoid of information. In fact, it actually included its name and details about the buried contents. This was already quite detailed. His original intention was merely to examine the difficulty requirements for obtaining this treasure, which would help him decide and prepare. Unexpectedly, there was an additional gain.
Perhaps it was because Alka and the others had previously gathered information about the treasures of the Vastin Empire. At that time, the records stated that the Vastin Empire's royal bloodline was very adept at manipulating flames, and many within the empire cherished the touch of fire. Therefore, it was speculated that the Vastin Empire possessed a fire-related treasure. This was the source of that information. It seemed this speculation was very accurate, allowing the Treasure Hunting System to expand its scope.
