One episode, Gui Wu's miserable sister (completed) Er Zhoumu, the sister who stays in Nuo on both sides (completed) Third episode, Sister Gin (completed) Four Eyes, the Dark Lord's Sister (Complete) Fifth episode, Sister Shiwang (ongoing) Because I signed the contract, many things cannot be changed, and because of the uneven plot distribution due to my writing style, Shana's plot will be less than Qianyuki, but I am really a biological mother, and Shana's plot will be added later. She is not a female supporting role, although it may not be felt in the text, but she has a self-destructive tendency due to the original world, and will not take the initiative to form relationships with other people. Qianxue doesn't like to communicate with other people that much, because at first she wanted to merge with her sister and give back things that belong to her sister. She didn't dare to get along with her sister, and she would disappear sooner or later. My sister also has irreplaceable advantages. She is my sister's reassurance, she is the creator, and she also has great computer skills. I thought about it and decided not to be so tragic and change the outline. By the way, I would like to disclose that the intelligent AI created by my sister will be the protagonist of my next book. Well, in fact, I have a habit of abusing the protagonist, so the focus is on Qianxue, who is a bit miserable. Both of them are my treasures, and I will try my best to give them a good ending.
