I Became a Blind Man and Was Abandoned. What Regrets Do I Have When I Entered Taoism with a Musical Instrument?

Li Tianxin traveled through time and space to a world where blood is respected. The good news is that his family is one of the nine major families in East Antarctica and has the highest level of holy blood. The bad news is that when he was eight years old, during the family bloodline awakening ceremony, Li Tianxin's bloodline was so thin that he could not awaken it at all. Overnight, he fell from being a star among the stars to being despised by everyone! What's even worse is that he was blinded on the spot, treated as an abandoned son, and thrown into the Tiangang Holy Sect. For ten years, his father did not care for his mother, and he ignored her. Ten years later, in order to squeeze out the last bit of value from him, his parents came to ask him to marry a girl from another big family. Just because he got closer to the saint in the sect, the saint slandered him and killed his fellow sect, and demanded his life to pay for it. OK OK! In anger, Li Tianxin simply abandoned his own bloodline and severed ties with the Li family on the spot. Didn't you say that I harmed my fellow disciples? Then I will kill the Holy Son in public and betray the Tiangang Holy Sect. What can you do to me? They say that I play with the broken harp in my hand all day long, and lose my mind with it. Little do I know that this is the token of the Lord of the Yinxu Temple - the top-level sacred instrument, the Nine-Jue Tianqin! He said that I couldn't awaken my family's bloodline, but I understood the true meaning of the great path that transcends bloodline, so what about the holy bloodline? From now on, it can only be the nourishment that nourishes my eye of heaven and the true meaning of the great road!
