Zhang San felt a bit confused and somewhat worried.
Clearly, those two had the ability to escape earlier, yet they didn't.
When they first saw him, they didn't have any murderous intent; it seemed like they weren't here to kill him but rather to ask about something.
Through the words the shadow said at the end, Zhang San suspected if they were here for Kaihuang's revenant.
However, Zhang San wasn't very sure and didn't dare to rashly enter the Spear's Secret Realm to ask Kaihuang.
He could only set the matter aside for now, allowing Officer Bi to properly interrogate the ten assassins they had captured.
In terms of interrogation, Officer Bi was an expert.
Although Zhang San wasn't clear about Bi's interrogation methods, as long as he could find out what he wanted to know, the methods weren't that important.
So, Bi took the ten individuals away and held them in separate cells.
Soon, the initial three assassins all confessed.
