This is a world of martial arts. There is a special kind of power spread in this world, which is called "spiritual power" by people all over the world. People can rely on the cultivation method to absorb the spiritual power between heaven and earth into their own bodies, transform it into their own power, and use it to conquer the world for themselves. Each person is divided into several realms according to the different spiritual powers in his body: Xuanqi Mirror, Xuanling Mirror, Xuanyuan Mirror, Xuantian Mirror, Xuanxian Mirror and the legendary divine mirror. The gap between each two realms is very large. However, each realm is divided into ten levels, and the higher the realm, the greater the gap. The world has been peaceful for 200 years. In 218 AD, four envoys from Starry Sky came to Sakura City to meet the emperor. They claim to have powerful spiritual power that can help the emperor unify the world and dominate the world. The emperor believed them and asked them to make suggestions. Sure enough, the four people lived up to expectations, annihilating other countries and winning in less than 3 years. Emperor Longyan was delighted and rewarded them with official positions and mansions. Later, these four people became more and more powerful and formed four families: Xuanyuan, Yehuai, Nangong, and Baili. They were further divided into four major sects: Xuanyuanmen, Qiankunbian, Yuyinglan, and Duotianlou. At this time, the Wuya tribe in the north also began to rise, and day by day a new race was formed - the demon tribe. People thought that the world had finally calmed down, but little did they know that someone was ready to make a move, and the war had just begun. . .
