Genshin Impact: Keli's Sister Is 100 Million Points Strong

[Pure plot flow (the plot is a bit complicated, and the introduction needs to be spoiled a little) + not brainless + not invincible (not particularly strong at the beginning, and in a few cases can't be beaten, but even though the defeat is glorious) + three correct views] Alias: "The soul passes through Sister Keli, but becomes the savior of Teyvat" In an accident, Ke Ran's soul was transformed into Ke Li's younger sister Ke Bing, a new member of the Knights and a new member of the Knights, the Ice Flower Knight. Through Keli's impression of her sister, she originally thought that Ke Bing was a weak and cute little girl. Unexpectedly, behind the scenes, she was the twelfth executive officer of the Fools. A ruthless man who even worked as an undercover agent to help Mond steal back the Heart of the Wind God. Later, I met Alice and found that she had actually mastered the magic of traveling back and forth in the modern world and obtaining modern items there. Alice found a Dharma book that contained power far beyond the laws of heaven. It was said to be written by a god like Truth. She soon gave Ke Bing super strength comparable to the Ice God. With such a Dharma book, the people of Mondstadt are completely immune to the curse of forbidden knowledge in the forbidden book area, and dare to explore the secrets outside the world, which promotes the development of Mondstadt technology. As a result, the country that was originally the weakest quickly counterattacked and became an existence capable of overpowering fools. However, in order to fully release the power inside, overthrow the laws of nature, and level the abyss, the only option is to find the traveler who mysteriously disappeared for unknown reasons... (As a reminder, the plot logic in the middle and later stages is a bit like World War II, and there may be a plot similar to "Mond Blitz Fontaine")
