"Please begin. Keep us up to date every thirty minutes," Rea said on behalf of Theo.
In that instant, Ruth's eyes flashed. "Roger."
After acknowledging the order, Ruth took out her bow and shot an arrow. This arrow acted as a flare, sending Walker and Coline two messages.
The first message was to tell them she had received the command. And the second message was to point out the direction where they should gather the monsters.
As soon as they saw that signal, Walker and Coline took off.
Coline excitedly disturbed all the monsters in the area by trying to cook them. In the end, she gathered a lot of monsters.
They were angry at her because they were almost cooked alive. Now that their number wasn't something Coline could handle, they launched their counterattack, causing Coline to be the one to run away.
