Aaron placed a barrier around the three people before turning towards The First, who was raising his aura-coated sword to the air while stepping toward him. Seeing his opponent ready to strike, Aaron too, clenched his spear and started to move.
The First was aiming at him, who was standing right in front of the barrier he had just created. If he dodged, the barrier would be destroyed. That was why he had to either deflect or block the attack.
In fact, it wouldn't be only the first attack he wouldn't be able to dodge. He was sure that these two pests would try to attack the barrier if he moved a little bit away from it. They knew that by doing so, they would either manage to capture those three members of unit 5 or drag Aaron around and exhaust him.
SHHHH SHHHHH
