After investigating the underground warehouse of the Soul Crystal exchange shop, Long Dangdang did not take any action but quietly left with his companions.
Once back on the surface, they headed in the direction of the City Lord's Mansion, based on memory. Upon entering Stone Gate City, the main tasks were threefold: one was to observe the situation of the city's garrison to ascertain the proportion of wraith entities the Wraith Empire had dispatched to the front lines. The next was to scout the Soul Crystal shop, and the third, and most important, was to try to locate the wraith altar in Stone Gate City.
Undoubtedly, the wraith altar in such a top-tier city was of the utmost importance to the Wraith Empire. If they could destroy such an altar, then the blow to the Wraith Empire would be imaginable.
