Upon hearing Nangong Xingchen's words, Black Impermanence Night Demon's brow furrowed even tighter. From Hua Zheng's perspective, he even thought that Night Demon's complexion seemed to become ever more ghostly pale.
Hua Zheng secretly squeezed Nangong Xingchen's hand, who gently patted Hua Zheng's hand in return, signaling him not to worry.
If the person who had arrived were someone else, Nangong Xingchen might have worried about how to handle it alone, especially with a weak ally like Hua Zheng. But since the one who came was the Soul-hooking Envoy from the Netherworld, Black Impermanence Night Demon, the situation was different.
Of course, this didn't mean that Night Demon's fighting prowess was insignificant, but rather that Nangong Xingchen knew Night Demon wouldn't make a move against her.
Since a fight wasn't going to happen, Nangong Xingchen had nothing to worry about.
