Genshin Impact: What Can I Do with a Ten-Year Head Start?

No female lead + everyday life + collecting little boys + Genshin Impact + expanding the worldbuilding

(This is my first time writing, so the beginning might seem a little strange.)

After an accident, Mu An transmigrated, but not completely.

He found himself in a strange space.

Time and space were both in chaos there.

There was no color in that space, not even black.

All kinds of voices filled his ears every moment. Some he could understand, others he couldn't. They all came from creatures that had once been there.

The good news was that, unlike the mutterings of the ancient gods, he didn't have to listen. He could block them out simply by focusing.

After filtering out those with intense emotions and the ones he couldn't understand, the remaining voices were all people telling their stories before ending their own lives, passing on their legacies, or describing what they knew about the space.

After an unknown amount of time, he cultivated an ordinary technique that he could practice in that space, along with many other abilities.

Even with the worst talent and the most ordinary technique, endless time could turn quantity into quality. An ordinary technique for cultivating inner energy became a divine art that let him live forever, be reborn from a drop of blood, and shape a body from a wisp of soul. But it seemed useless in this space. I have to find a way out.

At last, he found a way out.

He successfully found a compatible world of the same origin: Genshin Impact
