Negative Person from Another World

Here, time does not flow, space circulates infinitely, and every grain of sand can be seen clearly without the sun. Apart from me, there is no one, it is a boring space-time wormhole. Fortunately, my strength can still grow, so I accumulate what I have learned all the time. I don't know how long it took, but the space finally changed, and a huge crack appeared in the empty place. I walked directly into the crack without thinking. Traveling across time and space is very consuming, my body has been greatly damaged in the process, and I don't know where the next stop will be.
