First update.
***************
Xuanji had been searching in the vast empty hall for a long time but failed to find an exit. There were numerous forks and rows of corridors; she had searched almost every room in each corridor. There was not a single trace of anyone; it was unknown where Zi Hu had taken everyone.
At the time, they were led in with their heads covered, seeing nothing, only feeling that the place was immense and expansive. However, Xuanji quickly realized that even without her head covered, she would not have been able to distinguish the paths. This was because all the rooms here looked exactly alike, and the layout of the passages, their length and width were absolutely uniform, more complicated than the most challenging maze.
