Genshin Impact: I Am a Harbinger, and I Stole the Cryo Archon's Gnosis

[Genshin Impact + JoJo + Gacha Banners + Multiple Female Leads + Gender-Bending Yuri + Nearly Invincible + System] Sixteen-year-old high schooler Xinyuan was in a foul mood after getting nothing but 0+0 from 300 pulls in Genshin Impact, so he went outside for some fresh air. While crossing the street, he was sent to the afterlife by the Four Horsemen of the Apocalypse. To his surprise, he was transported to the world of Genshin Impact and became a beautiful, white-haired, blue-eyed girl. In the freezing wilderness, the Tsaritsa found him and brought him back to the Fatui. He became the Twelfth Harbinger, the "Princess," and awakened a System. But the System told him to steal the Cryo Archon's Gnosis! Xinyuan: Can I win? System: You can!
