Scavengers Who Return to the Ruins

A man who has lived for hundreds of years discovers that the disappearance of his old friends is not fate, but the "erasure of existence" of Guixu - he is the only one who still remembers them, and he is also the next target on Guixu's list. The more he is erased, the stronger he becomes, swallowing back the existence that was taken away from him along the way, and finally returning his old friend to this world.
