What exactly is Bitao? No one knows. Some people say it is a world-famous treasure, some people say it is an unparalleled martial arts secret book, and some people say it is the secret medicine of immortality. Bitao is just a secret left by the first owner of Xinyu Tower. She is just the young Bitao envoy of Xinyu Tower, and she does not want to pursue the misty Bitao like many of her predecessors. But why leave? Why did you still give your whole life to Bitao? It's just because I have no more wishes for the rest of my life, but it's just because I don't want to suffer for the mirror flowers and moons that once seemed to exist. It was just too confusing and complicated, she thought. That's it! Let the warmth and affection, laughter and tears, blood and cruelty all flow away with time. When one day, she becomes interested in the so-called love and the entanglement of love and hate, she will think about it again and again.
