Here is the main text ~ Original name: I was a miracle doctor during the Demon War Current name: As a wet nurse, how should I survive during the Demon God War? The text is in third person. Copywriting one: Born as a demon, I was supposed to lead my people to kill everyone and conquer the world. Bad news: I am a healer and a nanny. I am destined to have no luck in fighting and killing. How should I survive in the cruel demon war? Good news: I was picked up by Gui Li when I was still in the eggshell, and my home place at the beginning is Guiliji. Ultimate achievement: Together with Emperor Yan and other immortals, he established Liyue. After working as a military doctor for half his life, he successfully lived a peaceful life in Liyue where he occasionally went out to see patients. Copywriting two: The first person I saw after breaking out of my shell was my sister. My sister is called Guizhu, the Demon God of Dust. She likes humans very much. She once said: [Those little people are as small and fragile as dust, but they always work hard to become smarter. I understand. Not only does my sister like humans, I also like humans. For they will give me fragrant food and sweet fruit. Even though he is weak, he can still stand up and defend his homeland. But there are always other demons coming to grab territory and fight. The houses built by humans and the food cultivated by humans will always be destroyed by war. But they never complained and were never afraid. Moreover, Uncle Morax and other immortals will protect humans. My power is different from that of ordinary demons. It doesn't have that strong a force value. But I will heal, no matter how serious the wound is, it doesn't matter. Um! It's decided! I want to learn medical skills! Catch both external and internal injuries! May the people in Guiliji always be healthy! ——I was born only two years ago and I have great ambitions. Things to note: 1. CP mandrill 2. The timeline is confusing and there are magic changes, please don't pay attention to it. 3. There will definitely be OOC, but I will try my best to avoid OOC! 4. Please forgive me for my noob writing style. 5. The heroine's demon name comes from Malbus in The Seventy-Two Pillars of Demons (previously the author assigned another transliteration of the Xiaocao God's demon name to the heroine) (twisting) (sorry) Bow and thank you. Purpose: Treat illnesses and save lives
