Girl from a Thousand Years Ago

In South Korea in the fifth century BC, sixteen-year-old Luo Xiaochun was the doorman of Taoist Priest A and B. She mistakenly ate an immortality elixir that her master had refined throughout her life. Taoist Master A and B were furious and passed away, leaving only one last word: "This elixir will make you live forever, and it will also make you sleep for a thousand years every hundred years. Whether it is a blessing or a curse depends on fate." Thousands of years later, in 2026. The construction team dug a train tunnel and unearthed a tomb of a Northern Song Dynasty concubine. When the archaeological team was cleaning the coffin, a bolt of lightning struck the coffin lid on a sunny day, but the coffin was not damaged. Open the coffin - inside lies a richly dressed girl.
