Gu Zhen Ren
Now with the explanation of the immortal Gu master having their body transform to be in symbiosis with their path, I'm wondering, what would happen for a nothing Gu master ? A Gu master who never refine a Gu, not even a vital one, even if it's close to impossible, I really wonder what the Heaven and Earth would give inspiration to, how his immortal body would transform, would he become a Noting path Immortal ? Even if I'll never learn the answer, this quite interest me~
