Genshin Impact: I Am the True Lord Who Cleanses Evil and Brings Peace

[Heroine to be decided + plot revisions + becoming a gacha character + making up for some regrets + male lead gradually grows stronger + past events]

A young man is sent straight to Teyvat by a truck. When he wakes up, Hu Tao has taken him in, and he meets Zhongli, the old gentleman who roams the mortal world.

The boy originally thought his transmigration would be simple, but then he realizes there's something different about him.

It seems he's forgotten an important part of his memory: a group of important people and an important promise.

And so the boy and a Descender from another world set out on a journey to recover his memories.

"Little chicken, let's go."

"You're so noisy. Can't you two be quiet?"

"Come on, if you're so annoyed, why do you hang out with us every day?"

They had been carefree, but a world-shaking battle drove them apart.
