"Cui, have you recently felt anything unusual about your spine?"
When Xiang Shan asked this question, he actually felt a bit nervous.
Today, he had felt something odd about his own neck.
Specifically, when he flipped that behemoth that descended from the sky with a punch, he felt a stabbing pain in the back of his neck.
This was unusual. The sensors on the outside of his spine had been stripped away, and even if there were a sensation of pain, it should have been "phantom pain."
But when his fist collided with the sole of that giant's foot, he indeed felt pain in the back of his neck—a pain that was very different from "phantom pain."
After all, the giant's weight exceeded five tons. No matter how clever his force was, there was bound to be a rebound force.
And it was normal for this rebound force to permeate through the shock absorption system and act on the biological parts.
Yet, to feel "pain" was truly abnormal.
After all, Xiang Shan had no nerves that could feel pain.
