"There is a central imperial capital in the world, which is the capital of the Yu Dynasty. According to legend, it was the location of the Holy Garden thousands of years ago, and generations have worshiped the Holy Garden Temple. There are many large and small city-states on the continent, each with its own scenery. There is a city in the south, called Nancheng, which is the oldest and most prosperous city in the world. Generations worship the Sword Goddess. In the north, there are Tianshan Mountains that tower close to the sky, with snow falling all year round, and all the humans, animals, and birds in the world. It is rumored that the Sword Master has lived at the top of the Tianshan Mountains for many years, but no one has ever seen his true face. For a long time, it has become a legend. The nomadic tribes in the northwest have been fighting among the tribes every year. The desert areas outside the grassland have gradually become a climate, and they have repeatedly invaded the Central Plains. The black forest in the west is said to be the forest of death, and it is the location of the secret cult."
