"Roaaar!!"
Beyond the island came the resounding cry of a Magic Beast.
At the same time, a massive column of water shot up from the sea, piercing the heavens.
This Magic Beast had no particularly effective means of dealing with Charles and the others on the island. After letting out that cry, it sank beneath the sea and left.
Using Eagle Eye Spell, Charles watched the enormous fin cutting through the water and the broad back that surfaced from time to time, and could not help but speculate:
"Perhaps this is some kind of whale-type Magic Beast. Judging by the force of that attack, it must at least be a powerful third-tier Magic Beast to unleash such a terrifying strike."
"Fortunately, that Magic Beast can't come ashore. Otherwise, this base definitely couldn't be held."
"Whether I could even escape would be another matter entirely."
Even now, the thought left Charles somewhat shaken.
Among the teachings he had learned on constructing Outpost Bases, choosing the location was extremely important. Every choice could bring about a different outcome.
For instance, if an Outpost Base was built on the continent in a densely populated area, it would attract attacks from native armies or powerful individuals.
If it was built in the wilderness, it might face some powerful Magic Beast—or simply an attack by a beast tide.
Choosing an overseas location offered many advantages.
