Yu Tian no longer had any doubts about Barre’s identity. The only thing left to do was to Pry Open Barre’s mouth.
He was not a professional in this area, but as a doctor, he had a few tricks up his sleeve when it came to inflicting pain on humans.
As for interrogation techniques, he would need the support of the team behind him.
Brother Pig had never been interested in interrogation because he felt that the people who were hiding secrets must be very tight-lipped.
The things that could be casually said were either not of much value or false information.
The worst thing was that even if you spent a lot of effort and finally managed to pry open the target’s mouth, the final result would still be a false information.
That would be even worse.
It wasn’t like Piggy Liang had never encountered such a situation before. He had even been tricked.
