"He stabbed you because he was under a spell?!" Chen Han, Sun Yi, Li Tian, and Feng Mo said after Cheng Sheng explained to them what happened inside the Cave of Retribution.
"Yes." Cheng Sheng nodded. "The longer you stay there, the stronger the spell will affect you." He explained.
"But, how did Yu-ge reach the Cave of Retribution so easily?" Feng Mo asked. He's now back to calling Yu Sheng 'Yu-ge'.
"Didn't he disappear during the Zunjingde Sect rescuing Jing Hei and Qian Lin? That's how it is." Cheng Sheng explained. He and Yu Sheng already talked about their alibi while in the Cave of Retribution before they went back to Xinfaxian.
"Oh." They all nodded, finally understanding everything.
Cheng Sheng secretly sighed in relief. He doesn't want to lie to them, but can he tell them that he is Shen Qi and he's not really 'Chen Shen'?! "Let's just leave him here," he said after they finished catching up with each other and turned to Ruo She.
