From the first day Aurora was built—no, even before Aurora was built—Great Wall had already existed. For centuries, the sacrifices made by the Nine Families of Dragon Bloodline and boosts by countless musicians resulted in the Great Wall turning into a massive object that was almost like a catastrophe.
