Who I Am? Is It a Human, a Demon, or a Trick?

[This is the first time I write a novel and I feel free to correct any unreasonable parts. The author will make corrections based on my advice. This novel is a bit dark and if it doesn't look good, just comment on it and there is no need to cross it out] "Sun Xuan, such a vague title... Is this me?" "Daoxuan Zhenzu? Do I have this title? This is not me..." "Big demon? Is this me? Not me... This is not me..." "Quiet? Am I this kind of thing? No... I'm not..." "Where is my destination..." The road to immortality is long and misty, how long will this road take... Can I really hold on, can I make it to the end... No... I can only go on... Non-stop...
