Tang Dynasty: from a Sick Young Man to an Emperor Through the Ages

This is a not so serious Tang Dynasty. Li Xiu traveled back in time to the Ninth Prince of the Tang Dynasty. His predecessor was frail since childhood. After knowing the era he was living in, Li Xiu had the idea to change the future. But it turns out that this is the Tang Dynasty, where there are one religion, two alliances, three demons, four families, five swordsmen and six sects, and the knights use force to break the law. It was at this time that the breaking system awakened, which gave Li Xiu the courage to overcome obstacles. At this time, there is a parallel world, and the party is being detoured. Any similarities are purely coincidental. (Newbies, please understand if you are not sure about some parts. Everything is based on the setting in the text.
