While Pierre was looking for workers, Billy made some Earth rings and made them level up until they gave him extra twenty levels in Earth manipulation. Since the effects of each extra level were low, the skill points necessary were only fifty. Nevertheless, the effects of those rings escalated quite a lot, but because of that, they were losing durability over time.
"We don't have time to worry about creating optimal walls now. We will focus on what Pierre wants: surprise the enemy," Billy said on the next day while they were heading to the eastern side of the town. "I will raise the walls with some Earth pillars. Meanwhile, Sarah will fill in the gaps and connect all of them with their magic. That is necessary because they will be heavy, but not too thick."
"What about us?" Alexander asked.
Billy wondered for a second. Aside from Kate, their magic was above average, but it wasn't suited to long constructions like that. Still, any help will be welcome.
