BURN

"AHH... argh... AAAH"

A full minute had passed since the exchange of blows. 

the assassin was still on the floor holding his knee and screaming in agony... 

He still can't see, hear, or smell anything... even after Robin received that attack, the scope of darkness was still active, throwing the assassin in complete darkness as if he was cut off from the world 

the pain had completely shrouded even his spiritual sense, which was already muddled... He was now 100% under the influence of the dark realm, even if he wanted to escape, he wouldn't know the right way to go

As for Robin, he was still lying on the ground after the direct punch that hit him

Finally, after another twenty seconds, Robin was able to sit up, his arm dropping in a weird position as if he was about to fall, blood dripping from his head and mouth like flowing springs.
