The guild headquarters were the same as the guild office, they were safe zones that were designated by the system.
The main difference between the two was that you had to pay rent for the guild office, but the guild headquarters was a piece of private property. Once a player issued as challenge for a guild war, the guild headquarters would turn into a place that could be attacked.
There were very little members in the Quan Zhen Sect so it did not make sense to rent an office. They would normally just gather in the Inn. The only private safe zone they had was their headquarters.
But because of how lazy they were, the members of the Quan Zhen Sect did not visit their headquarters very often. If it weren’t for Spring Halo’s reminder, they would all have forgotten about it completely.
There were two ways to get to the guild headquarters. The first was through the teleportation formation and the second was to run there.
