Chen Yuan, a doctor from Tsinghua University, suddenly became Zhu Gaoxu, the king of the Han Dynasty in the Ming Dynasty - the man who was detained in a copper vat by his nephew and roasted into a "Crock Pot Chicken" in history. He immediately decided: Whoever wants the throne wants it. I just want to be a free prince, farming, digging, and doing scientific research. Take the initiative to ask for vassal status? The civil servant group impeached him with a paper: "Retreat to advance!" After being detained in the capital, he smashed the can of the emperor's grandson to promote weaving and wrote an article "Promoting Weaving" to wake people up; he conquered the Tatars in the north, defeated the Jurchens ruthlessly, and erected a monument "Those who cross the line will be killed"; he went to the south of the Yangtze River to uproot a century-old conglomerate. The three brothers shook hands and made peace in front of Zhu Di's bed, and the eldest brother lived twenty more years. When the world was settled, he led the fleet and disappeared under the Southern Cross, leaving a legend to the Ming Dynasty.
