Prince Supervisor: You Were Asked to Defend the City and Die, and You Became the Overlord of the World?

[Travel + History + Imagination + Farming + High Martial Arts + Strategy + Struggle for Hegemony + Upgrade] The enemy army is approaching the city, and the weak South Vietnam will no longer exist! When the emperor fled with his family, in order to preserve his reputation, he made the third prince Zhang Junlin, who was not favored and was sent to Huangzhuang to farm, as the prince of the prison country, and let him live and die with Jinling. "The third prince is useless. It is not a pity to die to protect the country and the inheritance of our ancestors!" Zhang Junlin came through time travel. He originally just wanted to guard his one-third of an acre of land to farm and gain enlightenment. But this scene of the emperor guarding the country and the king dying in the country really left him speechless. Since his father made him the prince of the prison country for the sake of convenience... Then he can only say that South Vietnam belongs to him, and the whole world belongs to him!
