Following their plan, Espi slept and recovered for the rest of the day before they started advancing again, luckily the biggest camp of the Storm Roc family was just right in their original rout anyway, so they didn't have to take a detour.
Thanks to Ixas skilled runes when it came to earth and the strange scales of Espi, they were able to approach the camp without raising surprises.
Something Aster noticed was that due to the light of the sun and moon, any kind of formations will erode and become useless pretty soon, Ixas countered it by lending enery from the most abundant element in the secret realm, in other words sand.
But the people from the poisonous branch of the Storm Roc family all had wind attribute, while their royal lineage has an extra poison effect added to their wind, so their formations were unable to work in the secret realm.
Espi dived into the earth and stopped there by Aster's command, like a predator eyeing its prey.
