If it's about the character...
The Divine Staff Sheath crafted for Yu Shujun with the keyword "break through shackles," is it hinting at something?
Why does a faceless woman always appear in Yu Shujun's test space? Who exactly is this person? Even Yu Shujun herself can't clearly remember, yet there she is, appearing unfailingly in every test space. Could it be that she's a character from some instance before Yu Shujun entered the furnace?
Moreover, according to the system in the Divine Staff Sheath, both the Divine Staff Fragment and the Divine Staff Sheath are top-tier equipment. Since they are equipment, they are made for players. Yet strictly speaking, Yu Shujun doesn't even count as a player, so why does she have such an obsession with the Divine Staff Fragment, becoming the Sword Holder, and repairing that Divine Staff?
These questions surfaced one after another, and eventually, an idea emerged in Wen Nan's mind.
