The Setting Sun over the Han River

At the end of the Southern Song Dynasty, Mongolian cavalry invaded the country, causing bloodshed in the world. Lin Xizhou ran away from home to find out the truth about his father, and accidentally got involved in the battle for the Jiuding Order. Master Yuanzhen of Guiyuan Temple taught Prajna swordsmanship, Zhao Wujiu of Tianji Pavilion revealed his father's life experience, and Shen Qingluan of Canglangfang was actually a Mongolian princess. The four of them exposed the treasonous crime of Prime Minister Shi Miyuan in Lin'an, and gathered the Jianghu sects to defend Xiangyang. Cheng Changfeng died in battle, Shen Qingluan died, Lin Xizhou understood the ultimate killing move of the Prajna Sword and repelled the Mongolian vanguard, but the Jiuding Order was lost in the melee and continued to travel the world.
