Crossing Teyvat and Then Becoming a Dark Horse?

Fang Yuan, this is my name, I am twenty-one years old this year. He was originally a food delivery rider. However, he collided with a logistics transport truck while delivering food. He was knocked back more than ten meters on the spot and rolled his eyes immediately. I thought I would die like this, but accidentally traveled to Teyvat and became a dark horse, starting a different kind of time-travel life. This novel and its characters are purely fictitious.
