Great Ming: Reborn as Zhu Yunwen, with the Capital Besieged from the Start

On the eleventh day of the sixth month in the fourth year of Jianwen, Zhu Yunwen is reborn. Only two days remain before Zhu Di breaks through the capital and Zhu Yunwen sets himself on fire. From the start, the difficulty is hellish: Zhu Di's 300,000 troops surround the capital, while spies are everywhere within the city, including Li Jinglong and Xu Zengshou. The dynasty's fall is imminent, but fortunately, he awakens the Heaven-Defying Fate-Changing System! He reorganizes the Embroidered Uniform Guard, executes the many spies, and takes back military control. He vows to face Zhu Di in a decisive battle at the capital. The emperor will defend the city gates, and not a single Yan soldier will set foot inside the capital. I, the Jianwen Emperor, am the Son of Heaven of the Great Ming! I will abolish the vassal states and never back down. I will protect every blade of grass and every tree in the lands of the Great Ming, make its power shake the four seas, and fly its banners across the world.
