From 1920 to 1925 in the Republic of China, "Tianyue Silk Script" reappeared in Pingjiang, attracting various forces to compete for it. Gu Qingyun, a teacher at Yuelu Mountain, was involved in the whirlpool due to the tragic death of his teacher and was forced to guard the silk books. He discovered that he was the orphan of the head of the Tianyue Sword Sect, and that the person involved in the massacre of the family was actually the head of the three current sects. Gu Qingyun is a weakling, facing survival crisis and development obstacles in a chaotic world. He must protect the silk book, find out the truth, and resolve family feuds and teachers' grudges in a short period of time with fierce competition from all parties. He was torn between love and truth, and finally understood that "a great chivalrous person serves the country and the people", grew into a generation of chivalrous people, and reversed the situation.
