The reason why Randy was not afraid of the cold energy that could pervade into his body and cause harm to him was that he was now in his full assimilated state, in other words, that there was barely anything that could cause any significant damage to his current physique that was on par with an S-Rank awakened's body.
Not to mention, his current dual-assimilated state which further improved his basic statistics, causing it to temporarily reach above the physical strength of a normal S-Rank.
Thus he was able to form a sort of ice blade with his hand from using the ice spell technique. Using the resulting spell technique, frost hand, he was able to inflict damages on the other party who seemed unfazed by his punching technique a while ago.
After a while of slashing the other party, he suddenly changed his pattern of attack and started to pierce them relentlessly all over their body instead.
Puk! Puk! Puk! Puk!
