I'm a Walk-On in the Multiverse

My name is Fang Xu. A native of Xi'an, on May Day when I just graduated from university, I went hiking on the Aotaixian Mountains and picked up a stone from the rubble. I won't talk about what happened next, it's very long. All you need to know is that I traveled a lot, met a lot of people, learned some crafts, and lost a lot of things. Finally I returned to Xi'an and opened a noodle shop. The noodle shop is not big, with a few tables, the stove is at the door, the chopping board is old, and the rolling pin was left behind by my mother. It opens at dawn and closes at dusk every day. When someone comes, I order a bowl of noodles. When no one comes, I sit down, wipe the stove, and sweep the floor. There is an iron wire hanging on the wall with a hook bent. I don't know which guest fell on it. There was a knife under the pillow. There was no blade, only a handle. There is a stone in the drawer, gray-white, fist-sized, exactly the same as the one I picked up back then. The days went by like this. It was leisurely, as if after walking a long way, I could finally stop walking. Occasionally, people ask me what I did before, and I say running a noodle shop. When asked where I had been, I said I hadn't gone anywhere, just taking a walk. The lights are still on. Noodles in the pot.
