In Genshin Impact, I'm the Strongest Sword Immortal

[Genshin Impact] + [Sword Immortal Protagonist] + [Fanfic] + [Everyday Life] + [Slow Burn] Ji Xueye was an ordinary student who had just started university on a blue planet. By chance, he used the power of the stars to transmigrate to another world. This wasn't a soul transmigration: his entire body crossed over, and he was still himself, unchanged in the slightest. Year after year, the years passed. The youth of old eventually crossed six thousand minor worlds and danced his sword through three thousand grand worlds. He became known as the number one Sword Immortal across all realms, but the journey of life is always unpredictable. During the war between immortals and demons, the Demon Lord knew he could not defeat Ji Xueye, so he resorted to a despicable scheme involving Ji Xueye's younger sister, Dongfang Bingxue. To protect her, Ji Xueye entered the primordial chaos. And so, his story with Genshin Impact began... Shenhe: “You liar! You promised you'd come find me at Mt. Aocang.” Ningguang: “When will we meet again?” Beidou: “Xueye...” Eula: “Hmph. I'll remember this grudge for the rest of my life.”
