After the Envoys left, Minister Sheng was really angry as he knew with the envoy getting attacked in their Palace during negotiations, war is imminent. Sure, the panther attacked the envoy because he tried to attack the empress, still if she wasn't here, this entire thing would have been avoided.
This Empress! This golden-spooned, privileged daughter of Huang AoTian...! Does she know what war does to the Treasury? WAR COSTS Money!!! A LOT OF IT!!! We are barely getting by lately and now a war..? How wasteful!
