[Transmigration and Rebirth] A Notorious Reputation

In this story, Emperor Yang, who had been on the throne for just one day in official history, transmigrates into a Sui-Tang novel and takes the place of Yang Guang, who is about to ascend the throne. Emperor Yang had only just taken the throne before transmigrating, so naturally he doesn't know that he will die young, that the country will soon fall, or that the Li Tang dynasty will replace the Sui. The timeline of the Sui and Tang dynasties is a complete mess, and the characters' ages don't match up either. The author has written it according to their own understanding. Also, the reason this is called a Sui-Tang fanfic is that the author has read too many Sui-Tang novels and watched too many adaptations, and got them all mixed up. In this setting, after Yang Guang transmigrates, his mother isn't Empress Dugu, but a transmigrator whom Yuwen Yong of Northern Zhou personally named a princess. This transmigrator came from an apocalyptic world in another plane and has supernatural abilities. Yang Yong is not Yuwen Zhiruo's biological son, but was born to Empress Dugu. Empress Dugu died in childbirth when Yang Yong was born, and Yuwen Zhiruo is Yang Jian's second wife. CP: Original Luo Cheng, strong x strong, pretty gong and pretty shou. Before transmigrating, Emperor Yang's reputation was: "His virtue in letters and arms is unparalleled; all under heaven praise Guang as a worthy ruler." After transmigrating, Emperor Yang's reputation is: "Lustful and lecherous, sinister and deceitful, murdered his father and brother, utterly brutal... His crimes are too numerous to record." Before Emperor Yang transmigrated, the Sui dynasty was like this: the realm was united, and the people lived in comfort. After Emperor Yang transmigrated, the Sui dynasty was like this: the countryside was full of bandits, the court was crawling with old coots who abused their seniority and lunatics, there were countless treacherous officials, the regional governors ruled independently, the realm was on the brink of chaos, and the country was about to collapse. In short, this is the sad story of Emperor Yang, still a remarkably wise ruler in official history, transmigrating into the infamous Sui emperor Yang Guang from The Romance of Sui and Tang. Note: Qin Qiong, a supporting character, is reborn; an ordinary modern man with a science and engineering background transmigrates into Yang You. Theme:
