He Guoqing knew how serious the crimes he had committed were, so coming clean and asking for forgiveness from Yang Zhengang and Sun Yuanhang was absolutely out of the question. Therefore, he decided to play dumb and pretend to be confused.
He believed Wang Yu had found his way here through the testimony of Ah Ling and Chen Cheng, and also believed that Wang Yu had no evidence to incriminate him; otherwise, Wang Yu would not have wasted time talking nonsense, but would have just arrested him upon entering the base.
Having the confessions of accomplices but no evidence only proved that he was a suspect of espionage, not that he was a spy. This point was very clear to him. So he believed that as long as he kept denying everything, Wang Yu couldn't do anything to him.
