"So we have a mole!"
Fan Xian and Xin Qiwu both said it dramatically at the same time, then went quiet afterward. Both of them believed that the head of their spies in Northern Qi was not a man who would give in under torture. Since they were so easily able to capture Yan Bingyun, and knew his real name, it was very clear that there was someone hidden in the Qing court who had an agreement with Northern Qi.
Xin Qiwu shook his head. "Before this incident, even the Crown Prince and I hadn’t known that Yan Bingyun had gone to Northern Qi. I believe that there are no more than five people in the court with appropriate clearance for this information. Even a fool would not believe that one of them had sold out our country. There must always be a benefit to someone committing treason, and in truth, His Majesty had trusted these people with running the country, so what benefit would treason bring?"
