Genshin Impact: The Yaksha Sent Me Packing from the Start

About the protagonist's three personalities. First personality: Ling Mengxue, female. Her soul transmigrated into Teyvat and became a boy, so from the protagonist's point of view, she's referred to as “she,” while others see and refer to her as “he.” Second personality: The Chef, male. He doesn't care about his appearance or gender, and usually uses the body of the Heavenly Principles, appearing as a woman. Third personality: The Heavenly Principles, female. After taking over the heroine's body, she appears as a woman. In fact, she isn't the heroine, but another soul. [No System + Slice of Life] Synopsis: Ling Mengxue has three personalities, suffers from a mental illness, and is the heir to a top-tier wealthy family! She is currently being held at the best psychiatric hospital in City A. [Ling Mengxue's primary personality: Codename “Mortal.” Lively and compassionate, she loves standing up for the underdog, or, as it's commonly called, meddling in other people's business.] [Second personality: Codename “The Chef.” Enjoys making all kinds of disgusting dishes and forcing others to eat them.] [Third personality: Codename “The Heavenly Principles.” A short-tempered personality, and an extremely dangerous one.] One day, Ling Mengxue was frantically spending money on in-game purchases in her hospital room. As long as she had enough money, how could she fail to get what she wanted? But all she got were Barbara and maids! She'd heard the game had a pity system, so she angrily pulled a thousand times. The result: a C6 Jean and two Qiqis. Though she'd only started playing that day, even she could tell how terribly unlucky she was. She spat up blood and passed out. When she woke up, she discovered she'd transmigrated to Teyvat! Standing before her was a handsome young man, though he was a little short. “Such a handsome face. What a shame he's so short.” “Bane of All Evil!” Ling Mengxue had just arrived in another world, only to die. Her journey in this new world began with death!
