Great Ming: Lending the System to the Hongwu Emperor from the Start

What if Zhu Yuanzhang had a portal that could take him to every plane of existence... If he returned to the end of the Ming dynasty, he would see the entire 276-year history of the dynasty, as well as his utterly bizarre descendants one after another. And the Chongzhen Emperor, crying as he begs his ministers to lend him money. If he returned to the late Qing dynasty, he would see a shattered realm, foreigners swaggering about, and a land of China weakened by a century of decline. If he faced the newly risen Mongols once more, he would battle the invincible, unstoppable Mongol cavalry... Zhu Biao really wants to know what choices this legendary Hongwu Emperor would make when faced with all this. My name is Zhu Biao. I transmigrated to the first year of Hongwu for one reason only: to give Old Zhu a cheat code.
