Even though he was imprisoned, Gu Fanzhou's face showed no signs of worry, just a paler complexion.
The paleness was due to the torture he endured.
The Golden Core Expert who captured him was no kind person, and had directly resorted to interrogation at first. However, Gu Fanzhou had resisted and said nothing.
Moreover, other Golden Core Experts arrived upon hearing the news, making the Late Stage Golden Core Expert apprehensive about using extreme measures, so he could only imprison Gu Fanzhou temporarily.
Every time Gu Fanzhou was interrogated, all the Golden Core Experts paid close attention, as they all wanted to ask about the whereabouts of the mountain gate token. However, none of them wanted the others to know.
The psychology of these Golden Core Experts consequently meant that Gu Fanzhou wasn't subjected to severe torture.
