Two ideas to try out
Biên tập viên: Kurisu
When Song Shuhang received the information that the other party's sense of existence had been erased, he subconsciously thought of the Wielder's small black room. When it came to erasing one's existence, the only thing he knew could do such a thing was that place.
But after giving it some more consideration, he found something amiss.
If it really were the Wielder's small black room, then these steel fish and their lair should have completely forgotten about the existence of their 'princess'. Meaning that they should have ended up forever 'collecting energy' until they were destroyed.
However, these steel fish still had some information about their princess, and they still remembered that she had long hair.
As such... their princess might have met with some other accident.
There was also a possibility... that she was already dead.
