Three-Pointed Peach Blossom Evil

I, Su Qingci, have the ability to "look back" and can go back to any point in time, but every time I use it, the price doubles. The first time, I blocked a fatal sword for him, and he said he owed me his life. The second time, I reversed the tragedy of his family being wiped out, and he said with red eyes that he would never let me down. This time, for the third time, the price was my very existence. I activated my ability when he needed me most and went back to the day we first met. This time, he still whispered to me gently as in the script. But I chuckled in his ear: "Xie Yunlan, this time I will kill you with my own hands."
