Tianjing, Underground Research Institute.
Interestingly enough, although the Great Wall was now Xuan Kingdom's highest-profile Transcendent organization, it did not actually have so much as a headquarters.
There were two reasons. First, they were not a 965 or 996 work unit, but a 007, twenty-four-hour cultivation organization. None of its members had such a thing as vacation. They were either away on assignment, cultivating, or studying, so they had no need for a fixed workplace.
Second, the Great Wall's true leader was Chief Ren, and Chief Ren simply could not leave the Scattering Spirits Space. Were they supposed to let Chief Ren participate through video chat whenever they held meetings at a surface headquarters...?
You Jian strongly supported establishing a base on the surface, so they could leave Chief Ren behind and hold meetings themselves in the future. In his words: "It's not that I can't endure hardship, but is it really necessary to hold every meeting where you take a dump? You're making us look like some lowlife villain organization that holds meetings in a toilet..."
Chief Ren then directly sent You Jian into a toilet and set up a barrier to confine him.
You Jian took twenty-five minutes to break the barrier, twenty of which he spent carrying out major metabolic activities. One could not help but sigh: what did not kill him truly made him stronger. After that, no one ever brought up the issue of a headquarters again.
As a substitute, the Underground Research Institute basically served as the Great Wall's base, and newly recruited Measures would all study and train there.
As for the veteran Measures and Mountains and Rivers, the state had basically arranged proper accommodations for all of them. Even You Jian, who flew around all day, had a manor rented to him
