Yan Cheng had just arrived and hadn't had the chance to report on the assassination attempt when he suddenly caught sight of Zheng Nianru.
Surprised, he almost died of shame when that assassination attempt failed. Instantly, he developed respect for his current young master. Yan Cheng originally thought this ordeal was to humiliate them, not realizing that even after so many years within the Imperial Palace, they had failed to detect the presence of such a formidable opponent, who was in no way inferior to the Hidden Guard by the Crown Prince's side.
But the Fourth Prince had discovered them, and had already realized that they were at a disadvantage with a few casual remarks.
In his shame, Yan Cheng nonetheless took action. As soon as he calmed down, the first thing he did was to approach the hostage from Nanmen State.
