Nisheng determined that Qi Yu was the person she wanted to protect in her life, and she tried her best to protect him, even at the cost of replacing him and becoming the "Dark King" who contained countless sins. She once thought that he was everything to her, the person she wanted to protect with all her heart. But she didn't expect that he would eventually betray her for the so-called "justice". "I don't resent being betrayed by you. I don't hate dying in your hands. I was too stupid to think you would care about me. But why did you betray me for that so-called 'gentleman'? I betrayed the whole world for you, but in the end, you were the one who misunderstood me the most."
