I remember the protagonist seemed to be longer living than his peers (or have immortality), comprehending some sort of funeral music magic after one of his close friends die. I believe he originally had a close friend in the outer sect which was a son of luck. This close friend was eventually crippled, however had some adventures. The max in the place protagonist was living was nascent soul or golden core, and when the protagonist was able to leave, he found that his friend had a huge reputation and strength outside, but was missing. He was also an alchemist and paid close attention to one of his other friends bloodline after they die
