A long time ago, there were three realms: gods, demons, and humans. But gods and demons clashed because of the human world. For this reason, a war without gunpowder began. The human world is very ashamed, but it has found a sword that can split the world - the Red Blood Sword. It could stop this war, so the human world sent people to find it and embarked on the road of red blood.
Intention: Be brave and strong
