Just like the Astronomy Bureau and the Secretary Bureau, which seem to exist only in textbooks and cannot be found on any map, the Special Service Bureau's Containment Department is also a "non-existent" division.
The last time Bai Shanshan broke out of prison, she nearly blew up half of the Special Service Bureau headquarters. When Li Mumu revisited this place, she found that it seemed to have no signs of being remodeled at all and still retained the primitive state she remembered.
It's unclear whether the Special Service Bureau has mastered that kind of mysterious magic to restore things to their original state as seen in magical creatures movies by the Federation wizards.
The Containment Department is an independent dimensional fragment, once you enter you can't get out again. Unless you have a formally registered work permit from the Special Service Bureau and also apply for access permissions proactively.
Otherwise, you can only exploit a BUG.
