When people were still surprised, they realized blood was oozing from the seams of the steel armor on Ning Haotian.
Jiang Chen turned out not only to have gained an advantage, but also to have heavily injured his rival.
Otherwise, with his character, he wouldn't have said that.
The armor on Ning Haotian cracked, allowing people to see how bad his injuries were.
The fist power had pierced through his armor to hurt his carrier of martial arts. Since it had been a fist rather than a knife or sword, there shouldn't have been any visible wounds, but Ning Haotian's bones were broken. They had pierced through his skin, leading him to bleed heavily.
"I thought he had spit up blood in anger, but actually, he was injured that badly."
"Jiang Chen's fist is terrifying."
"In his current state, fists are, indeed, better than a knife or sword."
