Military exploits require swift action, and this concept is not limited to the battlefield—it can also be effectively applied in the political arena.
Especially in the immediate aftermath of an unexpected incident when nobody holds any strong cards, those who act faster naturally gain the advantage.
Take the case of Ma Xuansheng, for instance—the first to interrogate at the scene of the crime would not necessarily learn the same things as those who arrived later.
Because the first party on the scene, as long as they deal with the witnesses, can cover up the truth and simultaneously feed false information to other forces, thereby controlling the development and outcome of the situation.
Old fox Han Yu would certainly understand this principle, so the moment he received the imperial decree to "investigate this case alongside the Jinyi Guard," he immediately headed straight to the Southern City Military Department.
