This is a country called the country of knights, but this happened a long time ago. Many years ago, the evil demon rose up and invaded this country. The knights and the army resisted together, but in the end they failed. The knights who failed in the head-on confrontation went to the countryside and remote places to cultivate the next generation of effective forces. Hoping to drive the demons out of their own country, the new generation of knights has indeed become a force that the demon clan cannot be underestimated. Just when the demon clan was retreating steadily, the ruler of this country actually commanded the army to attack the knights. The king had surrendered to the demons. This tragic battle was called "Dang Yao" in history.
