Nangongbao is famous in the martial arts world for his swordsmanship and is known as the best sword in the martial arts world. The Lord of Nangong Castle, Nangong Deze, is highly respected in the martial arts world and has a far-reaching reputation. He and his wife Yu Mingyuan had six children, among whom the eldest young master was Nangong Ao, the second young master was Nangong Yun, the third young master was Nangong Yan, the fourth young master was Nangong Sheng, and the fifth young master was Nangong Yi. All of them were outstanding in martial arts and were known as the Five Young Masters of Nangong. The five young ladies of Nangong are all engaged, but the sixth young lady, Nangong Jing, still has no owner. Legend has it that the Nangong family has two treasures: one is Nangong's swordsmanship, which is famous in the martial arts world, and the second is the sixth young lady Nangong Jing. He already knew ten thousand words at the age of 16, and now he is proficient in playing chess, calligraphy and painting at the age of 16, and has a beauty that would even put Xi Shi to shame. The only shortcoming is that he does not have the superior martial arts skills of his brothers. Fortunately, Lord Nangong does not insist on it. A little knowledge of the three-legged cat kung fu is enough. Nangong Jing was loved by thousands of people in Nangong Castle, and the world called her: "This girl should only exist in heaven."
