Explanation & Understanding
Xie Feng could easily shake off Shen Xinya and it would even be easy for him to harden his own skin by filling his insides with compressed air bubbles. After all, Shen Xinya was just a normal human without any physical or magical abilities that would help her teeth pierce through from his jacket to the T-shirt he wore underneath.
However, Xie Feng did nothing but stand there silently.
It was clear that Shen Xinya really intended to hurt him because Xie Feng felt her teeth digging hard into his jacket and as a result they dug hard into his skin. Even though it was not directly, the human's jaw was one of the most powerful jaws that existed on earth so a bite like this could not be underestimated.
Xie Feng gritted his teeth to avoid grunting from the pain and instead of pushing her away he wrapped his arms around Shen Xinya's slender waist, pulling her closer to him.
