Han Dong had always been active in the Black Tower's plaza and its surrounding area, which all belonged to the Lower Zone (the inpatient department corresponding to the Fight Club was set up outside the Black Tower).
Any outsiders participating in the Black Tower, upon arriving through normal channels, would appear in the Lower Zone's plaza area.
Moreover, most of the transfer station activities (various transactions, mission handovers, reward exchanges, information queries, and the joining and activities of related organizations, etc.) could be completed on the Lower Level.
Large organizations like the Fight Club also had their main bases in the Lower Zone; even the Headless, beings equivalent to the Old King, were active in the Lower Zone.
The hierarchy of the Black Tower was not an indicator of an individual's strength but was related to Black Tower Authority.
In many cases, there was no need to go to the Middle Level.
