After giving his place a very normal-sounding name, Chaos decided to move out and do all sorts of things in this day. He decided to expand the entire walls to make up more space. He reinforced them with thousands of runes by spreading his divided body clones to hasten the process, and he created more houses for the inhabitants.
He also began to construct a large barrier above the entire city through the walls. He made the walls, the castle, and the ground into catalyst, filled with mana, to generate a powerful chaos barrier that would protect the entire place even from the deadliest of beings.
To make this even possible he had to make countless Runes all across these places, runes over runes over runes to be exact! If it wasn't because he had eaten the Demon of Runes, which gave him the power of creating runes without an issue, he would had taken even more time than he did.
