Parashurama was speechless to the point that he could not rebut against Jin. It was a resounding defeat through overwhelming power but he did have fun for the longest time ever. Surely, he got fed up with the Water Clones but when he had clashed steel with them, they could withstand his attacks.
It had been a while since he had fought to the fullest and utilise his strength however he wanted without setting or restraining his controls. The only time he did that was when he clashed with the demons.
