Riku provoking them with his words because why not? No one had any idea how his weapon exactly work. At the same time, none of their shields or armor could block his rapid attack.
"It's your call... Do you want to continue the invasion? Or each one of you could safely back to your place and lessen the people who died." Riku was letting Xelin pick choices even though he already knew the answer.
In his opinion, he could not see by their eyes that they would retreat in this invasion. Or to put it simply, the attackers had an idea of what we were going to happen to them once they come back to the Rattin Kingdom without the victory. Of course, all of them would die as the King's order.
Tsk!
From afar, Xelin clicked his tongue and followed up with a smirk on his face. Yes! He was felt insulted after hearing this man's words, however, he was aware that it was not the right time to fall back.
