after the self breaks into particles at the moment of death, the particles are sent to the zero-world and used again for a new world. The record of the past, however, is preserved just as the body is preserved in a freezer. The whole life of the past can be activated again in the mental world when Neutro gives another chance. No existence of the real world is extinguished in the zero-world. In fact, it does not end to exist but just disappears from the real world.
