Tai Yinzi didn't know what Gaia meant by the Eternal Kingdom—the club might very well originate from this place.
If that's the case, it almost explains why, as a Black Soul envoy, he is granted the authority to command Gaia.
This place is referred to as a treasury... but it is very likely just a warehouse of the club—after all, the club's internal space is far more spacious than it appears from the outside.
Then, it's quite normal for the club to have a warehouse for storing things outside, right?
However, Gaia said she does not know You Ye, nor does she know the current boss—thinking this way, there seems to be only one possibility.
This warehouse is a legacy of the former owner of the club, and Gaia appeared earlier than You Ye—perhaps for some unknown reason, the previous owner did not hand over the items in this treasury to the current boss, and Gaia has remained here, never updating the information from the outside world.
