The Lingering Sound in the Cylinder

In 2088, all mankind entered the era of "cloud migration". When the body ages, the consciousness can be uploaded to the "Ark" cloud. However, a sudden logical virus caused unexplainable "synchronous alienation" in all uploaded consciousnesses. As a "scavenger" who specializes in cleaning up discarded data in the cloud, the protagonist accidentally discovers during a mission that the fragments of consciousness stored deep in the cloud are being reorganized by some kind of force into a brand new "digital entity" that transcends dimensions.
