Kang Chen's question was too direct, startling Han Xin.
He was stunned for a while before hastily responding, "Mr. Chen... I'm not, my parents and relatives are all here, how could I, how dare I be a traitor, these years, I've kept it extremely well hidden. If it wasn't for this unexplainable leak of our list, I would never have been discovered..."
Kang Chen stared into his eyes, observing any subtle movements closely.
Han Xin's eyes were anxious, but honest, and his micro-expressions appeared normal. He was just anxious and eager to prove his innocence.
However, none of this was enough to convince Kang Chen.
Because lie detectors were useless on people like them.
They were all spies, agents who had been rigorously trained. For them, their daily task was to lie incessantly, not only convincing others but convincing themselves as well that their lies were truth.
