Blood Beads

With the death of the third prince Amro Doomblade, his Blood Shadow Army became a chaotic mess. Their fighting morale was removed the instant they saw that their leader was killed by Cale. They threw down their weapons and kneeled down on the ground to announce their surrender. 

Blood Two and Blood Three also chose to surrender. Amro was already killed, so why should they fight?

Instead of fighting to death for a dead leader, why not just surrender? Perhaps Emperor Aventus would let them off, especially with the Celestial Sword Empire's need for strong experts.

Cale brought Amro's body with him and handed it to the emperor. The latter looked calm and stoic, but Cale saw that Emperor Aventus' eyelashes trembled the moment he laid his eyes on Amro.
