Is Ma San Kui the focus of the case? Yes, but he's not the goal.
Zhou Qing is also a key breakthrough target in the case, but breaking through Zhou Qing likewise isn't the ultimate purpose of this case.
Even Vice Minister of the Ministry of War Xu Hong, whom we now have "live testimony" to identify, isn't the ultimate aim of the Ma San Case.
Because, by Shen Hao's deductions and speculation, Xu Hong doesn't have the capability to control such a long-spanning plot. Combined with the missing details from Zhou Qing's confession, it clearly corroborates Shen Hao's earlier reasoning and deductions.
Xu Hong is not the ultimate mastermind; there's someone behind him.
Yang Yansi—aside from this National Pillar General, Shen Hao truly can't think of anyone else who could make an influential figure like Xu Hong work to the bone for him.
