Like if you attack him and the attack is not powerful enough to take him down then his body will adjust/adapt to attack then the same attacks will stop doing damage to him, like if you notice jinyoung and Daniel use similar attacks but after fighting with Daniel, jinyoung uses the same attacks but this he was just smiling and tanking all attacks and even jinyoung said his attacks should be dealing damage to him but they aren't somehow, same with ui Daniel , he was doing damage to kitae but after sometime kitae just started to tank his attack and ui Daniel ends up defeated , the nerve on his body could be a sign that his body is adjusting, so in order to beat him you need to do significant damage to him first and then use a attack that could knock him out before his body adapt to it, but it's just my wild theory
