It would be a lie to say that Xi Xing doesn't feel resentful towards Cheng Sheng. Not to mention that the Spirit Tracing Bell, which Cheng Sheng created, harmed Xi Ming, but the two of them also risked their lives to help Cheng Sheng save Fei Yin by going down the Abyss.
But, who told Xi Ming to teach him only how to love, and not to resent? Thus, although Xi Xing felt resentful, it was only for a short time. It wasn't Cheng Sheng who harmed Xi Ming, but the spirit servant. It also was their choice to help Cheng Sheng. He didn't force them. Thus, why should he resent him?
Xi Xing heaved a sigh. Cheng Sheng could see the change in his expression. Although he knows Xi Xing isn't a resentful person, he isn't the person to take advantage of others, although he had done it before, for some reason.
"I will definitely cure Xi Ming." Cheng Sheng promised. "Xi Ming is also my friend so I definitely won't let him suffer. I also owe him, and you, a favor." He smiled.
