How to Cultivate Immortality with Chakra [Genshin Impact Crossover]

Taiyi transmigrated after reading a cultivation novel on a certain web-fiction site. He became an orphan on the fringes of the Uchiha clan, in a village on an unfamiliar continent, and relied on his older brother, Obito, for support. After hearing the legend of the Sage of Six Paths founding the Ninja Creed, he immediately realized he'd entered the small world created by the novel's protagonist after ascending to godhood, the very book he'd been reading before dying of overwork. Since he remembers the cultivation technique the protagonist practiced, he's sure to shatter the void and ascend to immortality! But his good fortune doesn't last. Just as his technique reaches a small breakthrough and he gets to face-slap the people who mocked him, bad news arrives from the battlefield... Uchiha Obito has fallen in battle. Overcome with grief, he finally breaks through with his technique and ascends-- [Although the world he finds after ascending is a little different from what he imagined, that's not important.] Years later, when he returns to this place of sorrow, he discovers that his foolish clan has been wiped out. The wheel of fortune turns. Never bully a young man just because he's poor. Uchiha Itachi, I'll make you pay for this massacre with blood! Taiyi fights his way to an Akatsuki hideout, where he meets a strange man wearing an orange spiral mask. Tobi: I'm freaking out. jpg --◇◇◇-- [Hmph! Sending me a blade?] [You clearly have no idea how powerful Impure World Reincarnation is.] A classified Fatui report: the earliest records of the Fifth Descender, "Genin," came from the synthetic puppets they had stationed across Teyvat's seven nations. Catherine: Ad astra abyssosque! Welcome to the Adventurers' Guild. How may I help you? The Descender, who looked like a young boy, introduced himself: I'm from the Hidden Leaf Village. I'm an Uchiha. Catherine: Welcome to the Adventurers' Guild, traveler from Inazuma. Boy: You should know I'm good in a fight. I can kill people, rob them, break into houses, or set fire to mountains. I can do it all. Catherine, smiling professionally: ...You might be able to find work at the Dawn Winery. The boy found a job and held up the maid uniform he'd been assigned. "...?" [Diary: Day 3 after ascending-- This place is extremely dangerous and unsuitable for a long stay. That blond guy comes by every day to throw strange pink-and-blue hidden weapons at my head. He keeps saying things like "cross-dressing shota, huff huff" and inviting me to join his team.] [Diary: Day N after ascending-- In Inazuma. Politely turned down the Fatui's invitation, got a useless Electro Vision, and was about to usurp the Electro Archon... No, plans have changed. Why is that blond guy everywhere?!] Screenshotted March 1, 2021 Revised version screenshotted July 20, 2022 Theme: Let's go!
