The next day.
Theo was standing on the runway together with his group, watching a white airplane landing. It was a medium-sized airplane.
At best, the airplane could only bring twenty people. However, Theo noticed something different from this airplane.
"Mhm? It seems Maya has created something interesting." Theo smiled as if he was impressed by this airplane.
"This airplane doesn't have a sound?" Rea sucked a cold breath, understanding what Theo meant.
"By having no sound, you can stealthily fly in the sky. However, the airplane can't be too small or too big. If it's too small, the airplane won't have enough power to fend itself if a dangerous situation occurs. If it's too big, the airplane would only give their position away." Theo nodded in agreement.
"That's true."
They were waiting for the airplane to turn around and move toward them.
