'It might be impossible for others; however, as someone who was able to trigger two regular mission series back to back, I can do the third one, right?'
The Regular Missions from the Monster Horde Invasion, and the Barrier destruction, both were triggered by Aeon's actions.
Although he unconsciously triggered them, Aeon believed…no, he was confident in triggering a third series of regular missions.
Also, currently, Aeon is stuck with the tenth mission and can no longer trigger new regular missions, unless he does something big enough to force the Celestial World Tree to give him another series of regular missions.
"Aiden, pick one of three directions, West, North and South."
Once he thought of an idea, Aeon was not the type to delay it and take action.
"Huh? West"
Aiden didn't understand why his young master randomly asked him to pick a direction.
