Recruitment Drive
The King looked at Sam who is falling. His fall is too high. It would take at least thirty seconds for him to reach the point.
He decided to take care of the twins in these thirty seconds before he shifted his focus to Sam.
But as soon as he decided and was about to make a move, the twins lunged towards him directly and they held his hands with their bodies. Agar held the hand that held the staff and started heating the whole arm directly and Argan who is holding the hand with excess muscle which is being rejected by the rest of the flesh did the same.
The King was caught off guard. There is a reason why people don't usually make these kinds of moves. They might be easily executed once the opponent was caught off guard, but it was also dangerous for the ones who made the move and might backfire big time.
Particularly when the opponent is too strong.
