The Black Shadow Guards, the Purple Cloud Tower, and the Nine Cloud Palace had been busy looking for Xue Fanxin recently. They thought that the Ninth Lord was still in seclusion, so they only looked for Xue Fanxin.
Even if they were busy looking for someone, they were still paying attention to the people and things they needed to pay attention to. Therefore, what happened in the Imperial City did not escape their eyes.
As part of the five leaders of the Black Shadow Guards, Heiran and Heiyue knew more internally than ordinary people, so they knew a little about what had happened in the Imperial City recently, so they told Xue Fanxin all of this.
