There's no question that bone fractures hurt a lot, so someone who's never experienced them wouldn't be able to imagine what kind of pain it is.
If Chen Lie hadn't known about Gu Nianzhi's special body constitution, he certainly would have given Gu Nianzhi painkillers, because that kind of pain wasn't something a normal person could endure, but Gu Nianzhi rarely cried out in pain in front of him. Even when she told him it hurt a lot sometimes, if Chen Lie asked if she needed painkillers or not, she would reply that she could continue to endure it. If she truly couldn't bear it, then she'd take painkillers. And up until now, there hadn't seemed to be a pain that she couldn't tolerate. Physical pain, anyway. To Gu Nianzhi, emotional pain was much less tolerable than physical pain.
Under Huo Shaoheng's quiet gaze, Gu Nianzhi smiled. "...I'm okay. It doesn't hurt that much."
