Do you know about the end of the world? A great catastrophe once struck this land. All I remember is countless fireballs falling from the sky, and many living beings perishing in the disaster. What happened after that? The most powerful person in the world at the time saved it. He used up all his energy to shatter countless fireballs. They crashed to the ground, leaving countless enormous craters. Only the biggest fireball remained. Judging by the force with which it struck the earth, that one could have pierced the entire continent. The man unleashed all his energy and charged at it. What happened in the end? He saved the world, but then disappeared. Did he die? Who knows? Who was he? He was the undefeated king who once raised an army, dominated the whole world, and defeated Chaos. Ah, you must know by now. He was Chen.
