Zheng Fei wasn't truly unafraid of pain, nor was he truly unaware of death. It was only the power of the Evil Retribution Divine Skills that had long prevented him from encountering such a formidable opponent.
Almost all his opponents, upon learning of his Evil Retribution Divine Skills, would avoid him if possible, and flee if necessary.
Who's willing to truly perish together due to a disagreement?
The perish-together situations he had witnessed were all final acts of madness when one reached the end of the road. No one would willingly exchange their life when there was still a chance.
So, when his left leg was severed, he was still laughing.
When his abdomen was pierced, he relaxed the hold of the blade and instinctively wished to give Jiang Wang an opportunity to flee.
But when Jiang Wang's Longsword continued to cut, he couldn't laugh anymore!
