Genshin Impact: The Regret-Mending System Arrives from the Start

[Genshin Impact + System + Viewing + No Angst + Making Up for Past Regrets] A new writer's first work, mainly written to make up for past regrets. No protagonist, no CP, lots of elements, and a little fan fiction. One day, the System descended upon Teyvat and revealed Barbatos, showing everyone a god's life. Someone said, “So even gods have no choice sometimes, and even they have regrets.” Seeing how much Barbatos loved drinking, they realized that even gods could be so down-to-earth. Morax was revealed: “Only now do I realize how hard things were for Liyue back then.” Focalors and Furina were revealed: “One person bore five hundred years of loneliness.” “One god sacrificed herself.” The revelation shook all of Teyvat. The people of Teyvat said, “The strategist enters the game himself, hoping to gain half a move against Heaven!” I can't do this synopsis justice. Please read the story itself.
