According to legend, the Kuang family in the Rong Dynasty had a sword called Yukunfeng, with a gemstone named Guqiu on it. Many years ago, the discoverer of this gem, Si Longzi, presented it to Emperor Kai, who was overjoyed. Because of Silongzi's meritorious service in presenting treasures, Emperor Kai gave him the surname Yu, named Yulingyang, and granted him the title of Chang Huihou. The Yuhou was born in Silongyin, northwest of Hanling, and hid in the city. He was well-read in poetry and books, learned a lot, was ambitious, and was good at divination, but his talent was not recognized, so he named himself Silong. After Yu presented the treasure, Emperor Kai admired Yu for his talents and knowledge, so Emperor Kai ordered Yu to be the tutor of the prince. Since the prince Rong Wenran was similar in age to Yu, they were considered brothers. At that time, Yu was weak and Wenran was only eighteen years old.
Rong Kai and Kuang Fa are brothers with different surnames. Kai is good at riding and shooting, and Fa is good at swords and guns. They are very ambitious. Rong Wenran, the son of Rong Kai, became Rong II and ascended the throne after Emperor Kai abdicated on his own initiative. Kuang Fa was the Duke of Zhenguo. Fa had a son named Dingtian. Because of his merits in protecting the country, he was granted the title of General Fuyi.
He stood up to the sky and followed the law to conquer the southern land, at the age of sixteen. After the victory, Emperor Kai was overjoyed. Emperor Gu ordered craftsmen to insert Guqiu gemstones into his own sword Yunxianzhan, and after it was cast by two skilled craftsmen, it was as sharp as iron as clay. It was extremely sharp. He named it Universe Feng (Guqiu + Yunxianzhan = Universe Feng) and gave it to Kuang Dingtian as a reward. Emperor Kai told him that if the sword is in the Kuang family, the sword will be in danger if it loses its glory. After that, Yu, Rong, and Kuang hit it off and became sworn sworn brothers in front of the palace. Jade is the greatest, followed by Rong, and Kuang is the third younger brother. Today, Yu Lingyang, Rong Wenran, and Kuang Dingtian are all over sixty. Yu Lingyang lives in seclusion in Silongyin, Rong Wenran takes over the administration of Rong Dynasty, and Kuang Dingtian is still able to make a living, and can draw the bow of three stones.
