Lu Chengfeng, a top 985 doctor of mechanical engineering, accidentally traveled through the magical connection between a fragment of a three-eyed gun engraved with "Made in the 23rd year of Jiajing" and a glass bead and became Emperor Shizong of the Ming Dynasty, who was obsessed with monasticism. He abandoned his absurd obsession with cultivating immortality and used modern engineering knowledge as a "sharp blade of reform" to set off a subversive change in the Ming Dynasty - improving the matchlock gun into a repeating flintlock gun, inventing a hydraulic thresher and a siphon water pipeline to alleviate the people's food and clothing difficulties, building steam warships to strengthen the coastal defense line, and pioneering the establishment of an engineering school, a military education department, and an agriculture department, breaking the "scholar, peasant, industry, and commerce" The shackles were used to cultivate practical talents in the fields of machinery, military, and farming for the Ming Dynasty.
In the court, he fought against all opinions and defeated Yan Song's party members, and eradicated corruption with the "new system of official assessment"; on the battlefield, he personally led the Ming army equipped with new weapons to defeat the Mongol Ada Khan, and followed Zhu Di's example in sealing the wolf to Xu; at sea, he sent Qi Jiguang and Yu Dayou to train the navy, not only escorting the ocean-going fleet to resume the Zheng He route, but also pacifying the Japanese pirates and completely eradicating their influence. Su Jin's technical assistance, Hai Rui's upright administration, and Zhang Juzheng's strategic support outline a vivid "portrait of the Ming Dynasty's reform group." Lu Chengfeng's emotional restraint towards Su Jin and his insistence on "living for the people" add a bit more human warmth to the image of the emperor.
Just when all nations came to visit and the Ming Dynasty ushered in its prosperity, the glass bead suddenly shone brightly, and Lu Chengfeng suddenly woke up in Yanyuan Laboratory - the three-eyed gun on the case was still mottled with patina. A dream that changed history finally intertwined the virtual and the real, leaving behind profound questions about ideals, inheritance and historical choices.
