In his previous life, Chen Han was a video blogger who restored ancient technology and had tens of millions of fans. He traveled back in time to the 25th year of Hongwu.
At that time, the prince Zhu Biao passed away, Zhu Yunwen was about to be established as the emperor's grandson, and Lan Yu was about to be killed. As a distant relative of Lan Yu, he would also be implicated.
Chen Han, who was familiar with the trend of history, on the one hand wanted to save his own life, but on the other hand he also knew that Zhu Yunwen was incompetent, so he turned the tide and promoted the emperor's grandson Zhu Yunxi to the position of the emperor's grandson, saved Lan Yu and others, and also made himself the most trusted minister of the emperor Zhu Yuanzhang and the emperor's grandson Zhu Yunxi.
Taking this as an opportunity, Chen Han used his abilities to help the Ming Dynasty light up the technology tree and 'invent' steam engines, generators, telegraph machines, spinning machines, etc.
The Ming Dynasty Chamber of Commerce was established, and branches of the Ming Dynasty Chamber of Commerce were established in the Timurid Empire (India), Tsarist Russia, Japanese slaves, Nanyang and other countries. They monopolized the economies of other countries, controlled overseas trade, transported drugs to Western countries, and had drug wars with Western countries. They won great victories and forced them to sign treaties.
Eventually, he helped the Ming Dynasty colonize the world, and its territory spanned Europe, Asia and Africa...
