Earlier, the library in the spiritual world was smashed to pieces by Dou Shengnan. Now, without having been restored, it encounters this instance, and it's impossible for Xu Huo to condense the library back again. So, he can only simplify the process as much as possible, using just a spiral staircase to enter the depths of the library.
At this moment, there is only one table in the deepest part of the library. In addition to the materialized items representing Xu Huo's several personalities on it, there's also a black cube, which looks a bit like a square brick. It's placed individually, keeping a distance from the other materialized items.
Xu Huo has never come into close contact with this materialized item because it has been kept by the childhood personality since it was stolen. Even now, he does not fully grasp everything about the childhood personality.
In fact, the same is true for the other personalities.
