Sui and Tang Dynasties: Fake Surname Hongnong Yang

Yang Lang, the top student in the Chinese Department, passed through the great cause of the late Sui Dynasty for nine years and became a seventeen-year-old boy. The moment you open your eyes, it's the beginning of hell: you can't understand the dialects and slang of the ancients, you can't tell what year and month it is now, you don't even know your own name or where you are. In order to survive in these troubled times where refugees were everywhere and wars were about to start, he simply assumed the surname of Hongnong Yang. With his knowledge after a thousand years and his thorough knowledge of the Chinese Department, in the Sui Dynasty, when the clans were divided and war was endless, he gradually went from an unknown refugee to a son of a famous clan in the world. When the wheel of history rolls towards Jiangdu, can this soul from later generations change his destiny in troubled times and write his own legend of the Sui and Tang Dynasties?
