Was the Solitary World real history? This was a question worth exploring. The background of the story of Dugu Tianxia was the Northern and Southern Dynasties, which was the Northern Wei, Northern Zhou, and Sui Dynasties in real history. During this period, an outstanding martial arts novelist appeared. His name was Dugu Qiubai. Dugu Qiubai had once been a general of Northern Wei and later became a strategist of the Sui Dynasty. He was known as the " No.1 Master of the Northern Zhou Dynasty's Martial Arts World " and the " Wise Man of the Sui Dynasty " due to his profound martial arts and resourcefulness. Hence, he was nicknamed " The Solitary World ". Although the background of Dugu Tianxia's story was real, his works were not historical records. The story of Dugu Tianxia is a kind of wuxia novel. Its background and characters are fictional. His works mainly reflected the style of the ancient martial arts world and the grudges of the martial arts world, which had a certain literary and artistic value.
