After leaving, Theo began to search for new monsters to fight.
With Ava listening to their surroundings, there was no way Theo would meet other people in the surrounding area, let alone when the military assembled most of them.
At night, he visited Phyrill and discussed all the information they received from the military.
According to the military, the monsters planned to create a big war within a week. Hence, they planned to strike them to keep them busy in three days.
Considering how aggressive they were, this plan should be enough to give them one more week, allowing the reinforcement to take over and kill the enemies.
Theo also introduced himself to Phyrill's group as he planned to join their group for a while. Phyrill also told the rest not to bother him so much. Their relationship was mostly partnership after all.
