After Waking Up, She Struggled to Survive in the Devil World

As the first person in the immortal world, Qin Jiuqing lived for more than a thousand years. When he woke up, he found that his cultivation level had plummeted and he became a fifteen-year-old girl. The key is that she is still trapped in an iron cage and has to pay tribute to her arch-enemy Demon Lord as a tonic. Qin Jiuqing himself said: That's it? Take me as a tonic, Ye Chuling, do you dare to eat it? It's just that your cultivation level has plummeted. If you repair it for a few decades, you will still be crying for your father and mother. It's just... The idea is good, but things don't seem that simple and rough. This demon lord, please respect yourself and don't keep checking my aunt's window every day. We are not familiar with her! Not familiar? But that's not what you said before when you were eating other people's tofu. The Demon Lord held the sword and followed her pitifully to express his aggrievement. ———————————————— This is a story triggered by the ancient divine sword. One sword has two lives, one recognizes two masters, and life and death come from the same source. The person holding this sword will involuntarily get close to the other owner of this sword. If they are in harmony, they will live together, and if they are separated, they will die together. It's just that the two parties involved don't seem to understand this truth yet.
