Leonel's expression flickered.
The instant the Force surrounding the arrow lodged into his shoulder dissipated, he used his Variant Earth affinity to send it flying out of his flesh. The wound itself immediately began to heal, Leonel's passive Healing Factor having reached ridiculous levels after reaching the Second Awakening of his Healing Branch.
Isac hadn't expected for Leonel to deal with his wound so effortlessly, so he was somewhat caught off guard. This wasn't because he thought his arrow would be lethal, but rather because he expected Leonel to have to be forced to find a moment to pull the arrow out. And, he thought that Leonel would also have to at least weather the injury for the duration of the battle. But, it seemed that he was wrong.
Isac's expression fell for only a split moment before his determination was lit ablaze once more.
