Following his plan, Aaron proposed a plan of renting the horse wagons to travel from Emerald City citing the reasons like the long waiting time on a weekend and the crowd in the central city.
Furthermore, as flying is prohibited in the central city, they would have to take the road route but it will be very difficult to find six horse-wagons to travel either while traveling on foot is just humiliating.
But, how could they travel more than 3000km in horse wagons and reach in just four hours of time?
Hence, Aaron convinced the principal by stating that Arc Company will dispatch an expert to the Central City. That said expert has already set up a portal located outside of the city.
They can just go into the portal and end up on the outskirts of the central city. This works the same way as the teleportation formation at the portal point and doesn't have any long lines either.
