After Tang Zhen brought bone Emperor and the others back to the world of the spatial tower, he temporarily placed them in the spatial tower.
The cultivators who had returned from the other world to the world of loucheng were basically all gathered here. Firstly, the Holy Dragon City did not have much living space at the moment. Secondly, it was to avoid being discovered by outsiders and exposing their trump cards in advance.
This was the Holy Dragon city's hidden military camp. It would not be easily revealed until the war started.
The bone Emperor duo didn't have any objections to Tang Zhen's arrangement. They only wanted to return to the tower world. As for where they lived, it didn't matter. Not to mention, the tower world was relatively quiet and more suitable for cultivation than the outside world.
