One is a boy picking up incense in Kunlun Wonderland, and the other is an ignorant snake fairy by the West Lake. Just because of a kind thought that accidentally appeared in my heart, I was reincarnated in the mortal world for hundreds of lives. In this life, I have betrayed you, so I turned into the realgar love-cutting sword that you hate most, and I want to follow the person with the longest love in the world. In this life, I have betrayed you, and since you want to follow the person with the longest love in the world, I will follow this sword. Even if we stay in the mortal world for five hundred years, we still have to complete our love for a few days. But before that, Bodhisattva, please give me the word "forget"!
