I Slept for Two Thousand Years

Two thousand years ago, a young man brought a young boy to offer him the magic of immortality, but he was not trusted by the First Emperor. The First Emperor ordered the young man to use this magic on the boy. More than two thousand years later, the young man woke up in Xianyang, Shaanxi with wounds all over his body, and met the first noble person in his life here. More than two thousand years of reform have changed everything he knew beyond recognition, but the only thing that has remained unchanged is the magic that he was familiar with two thousand years ago, but today, two thousand years later, it seems to be called supernatural power.
