The Original God's Regret Wears People

After traveling for three days, he began to regret his journey, and Ah Tu, who felt intensely homesick, began to return home! What kind of story will happen after Ah Tu, who traveled to the continent of Teyvat for unknown reasons, discovers that he actually came to this world 300 years before the start of the main line of the game? The book was originally scheduled to be titled "Genshin Impact was 300 years too early to catch up with the main plot"/"Three days of traveling through time and beginning to regret the time travel, an unknown person's journey to a different world" It is a second creation based on the world view of Genshin Impact, and it will not involve many in-game characters.
