Genshin Impact, but World War

This is a world of Genshin Impact without yellow hair. The seven nations of Teyvat had many differences due to various conflicts of interest and politics, and eventually ended up at war with each other. The seven countries compete together vertically and horizontally. Who wins and who loses? The ancient underground country of Canria has quietly revived, where has Nata, the country of war, gone, and why has the Mondstadt expeditionary force, which has not returned from the expedition, not been seen for a long time despite the impending war. What will the maintainers of heavenly justice do on Sky Island? This makes the outcome of the war confusing, and all the results will be revealed in the book.
