A Journey Through the World of Genshin Impact: Interwoven Fates

I Read a Quick Transmigration Novel a Long Time Ago, but Can't Remember the Title

I read a quick transmigration novel a long time ago, but I can’t remember its title. In one world, the protagonist was the last god in existence, and the male lead was an emperor or a prince. In the end, the protagonist died as a god to save the world, while completing his mission to win the male lead over.

Any Stories Where Someone From Genshin Impact Transmigrates Into The Grave Robbers' Chronicles?
