"Well, that's because building the colossal magic tower at the top of the Red Goblin Mountains is necessary for us to acquire closer access to the mana currents in the sky and also allow us to monopolize the flow of mana," Vaan casually replied.
"Frankly speaking, a ten-thousand-foot magic tower might not be tall enough. So ideally, I would prefer if we could build a thirty-thousand-foot magic tower or even a hundred-thousand-foot magic tower."
"However, we can't bite off more than we can chew. Time, effort, and resources would be wasted if the magic tower crumbles due to flaws in its construction or if it gets destroyed by our enemies. Thus, we can only take things one step at a time," Vaan stated.
He would only consider upgrading the magic tower to thirty-thousand feet and beyond after stabilizing the situation in the kingdom and confirming the structural integrity of the ten-thousand-foot magic tower.
