320 Vol4 Ch45: Fruits of Sin

Normally speaking, the death of each Smith would transfer that individual Smith's power to every other Smith, eventually creating a super Smith. Such an entity might have been powerful, but he would have been useless to Rip Z.

The reason for Rip Z coming to this world this time was to help Xu Fu escape from this world and join the United Front against Negary.

One could even say that Negary was a highly strict and awkward father.
