Genshin Impact: Reincarnated as a Succubus, the Raiden Shogun's Fourth General

[Two female leads] [Succubus] [Demon God System] [Mengxue is 0, Shenzi is 1] [Very sweet, wish fulfillment] [No angst] When Mengxue transmigrates into the Genshin Impact world, she turns into a succubus from the start. Fortunately, the weak and helpless girl activates a System. It's called the Demon God System, and it certainly sounds impressive. But Mengxue never expected that activating it would require her to get physically close to someone else! Mengxue loses all hope. Turning into a succubus wasn't enough, now she has to offer herself up, too! Luckily, the System doesn't specify whether it has to be a man or a woman. In that case, Mengxue will just have to exploit a bug. “Um, Sister Shenzi, could you help me with something?” “Oh? Little devil, what could you need your big sister's help with?” “I, I want to... with you...” After activating the System, Mengxue thinks she'll be invincible, but it turns out she only gets rewards if she keeps snuggling up to people. “Somehow, I've gotten a little strange myself~” But there's no doubt about Mengxue's strength. She becomes the fourth great general under the Raiden Shogun, a mighty warrior. Even though she needs to replenish her energy at night, her fame still spreads across Teyvat. When Raiden Makoto is summoned by the Heavenly Principles to Khaenri'ah, Mengxue takes over her responsibilities and becomes the next Raiden Shogun. But no one expects what happens next... The Abyss invades. Mengxue carves her way through it alone, blade in hand. Even as the Abyss corrupts her, it can't stop her from moving forward. Only when her mind grows hazy and she falls into madness does Raiden Ei finally bring herself to strike her down... When Raiden Makoto is lucky enough to return from Khaenri'ah and sees Musou Isshin in Ei's hands, she realizes that it's all too late...
