Is that what happens when Kai finally counts all the bugs?
Technically, it's "all living things", so bacteria and viruses, etc, have to be counted.
Pedantic asshat time:
Viruses technically aren't living because they aren't cellular and are obligate intracellular parasites that require a host that actually carries out it's own metabolic processes.
I make this, admittedly, debatable distinction because viruses are weird. They're both evil and good. Evil in the sense that they destroy cells. Good in the sense that some of them change DNA, and changing DNA is an interesting endeavor.
I take a rather conservative view on this. They can't even seek out their own hosts. They just happen upon them or die. Life seeks out survival.
