Xu Wenwu arrived at the scheduled time, closed the door as soon as he entered, and asked, "Old Marquis, why haven't you left Stone City yet?" ,Yan Fuzhi had no choice but to honestly admit: "I am indeed the mastermind who killed Li Denian, but I am not the agent sent by the military command to break into the Stone City branch of the Secret Service Headquarters. I only killed Li Denian because I wanted to find a scapegoat. Because special high school put too much pressure on me, I had no way to find the arsonist. within three days. Not sure, the reason why he wanted to escape was because I asked Yin Qunli to threaten him, saying that he had been confirmed as the real culprit of the arson and would be handed over for the special high school, however, he himself has doubts, first of all, he was present on the night of the fire, no evidence can be provided to prove his whereabouts, and the technical equipment room he was in charge of was also burned down in that fire, so I don't think it's wrong to assign him as an arsonist.”
