Bai Yan is a strange person in modern society. She was raised by a man in ancient costume who liked to wear white clothes since she was a child. He also taught her kung fu skills that no modern person can do. In her opinion, the master is her only relative in the world. But one day, the master actually told her that the master was not the hero. He had raised her so that she could help him change the tragedy of history. However, this tragedy was actually caused by the master's mistake. What an unreliable master she had become. What's even worse is that my destined good match is even more unreliable. My next task is to go back to ten lifetimes ago to change our messy marriage and fate that was changed by Master. What should I do to change a thunderous plot into a happy ending?
