In 1628 AD, Tianqi died, and King Xin Zhu Youjian was appointed to succeed him. The seventeen-year-old young emperor faced a Ming Dynasty that was riddled with holes - the treasury was empty, Liaodong fell, and bandits were everywhere. The most terrifying thing was the powerful nine-thousand-year-old Wei Zhongxian, who was staring at him with a pair of black eyes.
But no one knows that the soul sitting on the dragon throne comes from another world three hundred and eighty years later.
His name is Zhao Chong, a Ph. D. In materials science from Tiangong University. He understands metallographic microstructure, fatigue fracture of high-temperature alloys, and everything about the temperament of metals. He doesn't understand the emperor's mind, he doesn't understand the strife in the court, and he doesn't understand how to live in the shadow of Wei Zhongxian.
But he must live.
