Five hundred years ago, the leader of the demon clan, Xue Longshang, sought to rule humanity. Joining forces with the mighty beast clan, he ran rampant across the human world. The fox clan was the only one not under the demon clan's control. They contributed their strength and fought alongside humanity, but the combined forces of the two sides were still no match for the demons.
Just then, a brave hero appeared in the human world. Taking up his sword, he went alone to the battlefield. Relying on his own strength, the hero sealed away Xue Longshang, the leader of the demon clan, and brought the war to an end. Peace returned to the human world, while the beast clan and the fox clan each returned to their own lands. Because of this war, the beast clan and the fox clan became sworn enemies.
People have recounted this war ever since. The hero was named the God of War of the Human World. The sword he wielded was black, but when infused with power, it radiated tremendous golden energy. The God of War used it to seal the demon clan's leader, and later generations called it the Demon-Suppressing Sword. The surviving demons fled in every direction and vanished from the human world. After the war, the God of War and his sword disappeared without a trace.
To commemorate this great hero, humanity erected a bronze statue of him. But during battle, the God of War had hidden his face behind a mask, so no one in the world had ever seen his true appearance. No one even knew where he had come from. His identity remained a great mystery.
