(The main thing I want to write about in this article is some if lines, scrapped drafts and second creations. The protagonist's ability is probably only to build a large-scale earth anomaly to connect the countries that once existed in the past with the seven modern world countries, as well as some of the most basic milk man abilities, and finally see the final sea of flowers with the travelers)
(This article contains the annihilation lines of Fontaine's "Prophecy" and Nata's "Skyfire Swing", the dark outer sea line of Heguan's "Ephesos" Abyssal Palace and the "Kingdom of Cloud Abyss", the advent line of the golden city "Hyperborea", as well as the unreleased "Poseidon Palace" in the south of Liyue, the "Whale Abyss" in the east of Inazuma, the "Flame Desert" in the south of Sumeru, and the "Dandelion Sea" in the north of Mondstadt.)
(Fontaine predicts the end of the world and Nata "Vicchilopochtli" basically strictly adheres to the official setting. Heguan and Yuanxiagong are the first civilizations before the "Burial War" of the second creation. Liyue South, Sumeru South, Inazuma East and Mondbei are all second creations. The timeline is roughly after the Fairy Rebellion and before the Demon War)
(The Advent line of the Golden City "Hyperborea" comes from the holy relic "Deep Corridor Finale" and includes two branch lines, "March" and "Third Advent". However, due to insufficient research data, only two were created)
(Nata's Sea of Silence was included in the Genshin Impact 5.8 Update, but the information is still too little, and there are only two creations at the time of writing)
(Weak water in the extreme north in winter, due to lack of information or about to be opened, there is no second record yet)
