Honkai: Star Rail: Changing Fate

[Purely fictional, and it doesn’t follow the original plot too closely. There may be parts that don’t make much sense, so please forgive me. It’s my first time writing fanfiction.][Jingliu is the sole female lead. Please don’t read if that bothers you.] The birth and fall of the Aeons, the fall of Cangcheng, the founding of the High-Cloud Quintet, the Shuhu Rebellion… You have more than just them at your side. You have me, too. I’ll stay with you until the story reaches its end. “Why do you think you can change fate? You know what it will cost.” “Do you need a reason to change fate?” “You know what the future holds. Why not just let it come to pass?” “Because the creatures of this universe don’t deserve such a fate.” “I understand. I hope you succeed.” “Then can I call you ‘Sir’ forever?” “Sir, what’s that?” “Sir, teach me swordsmanship. I want revenge.” “Sir, I broke that sword swinging it.” “Sir, I’ve become the Sword Champion.” “Sir, the High-Cloud Quintet has been formed.” “I told you, you have me at your side, too.” Chang Sheng is a life-form who came into existence with the birth of the universe, with power on the level of an Aeon across every Path. He wants to change fate, but his abilities are limited: he can only change the fates of a few people. Still, he’ll do everything he can to change fate, even knowing it may be impossible. Is regret all that comes of trying? He doesn’t believe so. He wants to find out.
