The incessant, intense stabbing pain from the narrow slit in the chest made Emperor Hong's complexion look extremely awkward.
It's not to say that the wound was particularly severe.
Although it looked like the flesh was turned inside out, running from the chest to the abdomen, very narrow indeed, such an injury can hardly be considered an injury to Him.
At His level, even if the flesh was destroyed and all the plasma evaporated, restoration would merely be a matter of thought.
It didn't even require a thought; the Heavenly Road would actively condense a new body for Him, a spectacle would arise from the fall of a king in King's Domain, much less so for Them.
The severity was in the fact that there was always some mysterious and extremely strong force at the wound, preventing the healing.
