Can you tell me the story of the finale of Legend Sword in detail? Thank you very much

Han Yunxi, a young man in ancient Wumeng, bears the tragic disaster of genocide, accompanied by an ancient fierce sword. He was rescued and adopted by Ziyin, an old man with a sword in Tian Yong. After losing his memory, Han Yunxi changed his name to Baili Tusu, which means "killing something congenial and awakening people's souls". Many years later, Tu Su was forced to leave his alma mater and travel around the world because of an inexplicable grievance. In the process of finding a solution to the problem of burning silence and Shaqi, I made friends with my best friend Ouyang Shaogong, the girl Feng, the half-man, half-demon Xiangling, Fang Lansheng and other warm-hearted and kind partners. Qinchuan looked for Yuheng, Iron Pillar looked for the wolf demon, Yaoshan looked for the fairy medicine ... Along the way, Tu Su went through all the hardships to slay the demon. Although he was burned by silence and ShaQi several times, he lost his nature. Fortunately, he relied on his pure kindness and strength. However, after several ups and downs, Tu Su suddenly found that Ouyang Shaogong, the most grateful and trusted confidant, was behind everything. In order to stop Shaogong's shocking plot, Tu Su laid down his life to unseal the fierce sword, and fought with Shaogong to the death with fearless sacrifice spirit, eventually turning all the joys and sorrows into ashes. And hope and the future, in this fire nirvana rebirth, married with snow shine.
