The Good-For-Nothing Fiancé of the Academy Chief

[Traditional fantasy + Machiavellian layout + no system] [Low Mystery + Chaotang] In the Sui Dynasty, every night at midnight, everything froze, and only the candlelight of the embers of time could illuminate the three-foot way to survive. No one knew where this vision came from, and no one dared to leave the house after midnight. In the eyes of the world, he was a good-for-nothing prince who would never live up to his prime. He was bound by an imperial edict to be engaged to Princess Chang'an. But no one knows that this "waste" entered the Four Realms at the age of ten and sealed his own eight meridians in order to survive. Now his meridians are crumbling one by one. When the mythical and legendary figures of Blue Star and the various schools of thought entered a different world, Qingfeng Li discovered that his identity was a mystery. Princess Chang'an's marriage is both a gift and a shackle. The imperial power wants to use this knife to sever the foundation of a century-old family. But they all forgot - the Li family in Shuzhou never raised idle people, let alone disabled people. No cheats, no system. Some of them are a group of family members who are crazier than the protagonist.
