Keroduo Mountain Area.
The effect of the Mist Barrier Legion Magic was astonishing; even when many other barriers failed, a few successful instances still summoned a mass of fog that covered several square kilometers.
And as the legion became more familiar with the Mist Barrier, the area it enveloped expanded even further.
If one observed from the Star Realm, they would see a tiny white dot appear in the Keroduo Mountain Area, then like paint dripping into clear water, the dark yellow of the mountain area would turn grey-white.
Outside the mountain area, the Galaxy Mayfly was shocked to find that their detection methods were extremely limited in the mist. What could typically scout dozens of kilometers could now only scout a few hundred meters.
Under these circumstances, nearly all the Galaxy Mayfly were unwilling to enter the mist.
