For Dongfang Yu, for example, he could absorb the Spiritual Energy inside, or at the very least, sell it for money.
Although the gemstones here are not priceless treasures, they are quite valuable.
However, he left without taking anything.
So, it proves that Dongfang Yu couldn't take the gemstones from here.
Gu Qiaoqiao researched for several days and finally deduced that the Treasure Room has mechanisms and Spiritual Energy, which would automatically activate protective mode when encountering outsiders not aligned with the Gu Family's aura.
It could also be seen as an alternative self-protection method aside from the murals on the walls.
This room would sink into the deep underground river, taking the intruder with it.
That's why Dongfang Yu dared not touch anything and just left.
Although it's speculation, Gu Qiaoqiao knows it's probably quite accurate.
That's why she dared to confront Dongfang Yu like this.
