How It Works
Activate Cauldron of Souls by tapping it, giving Derevi and Aerith persist until end of turn.
Activate Thermopod by sacrificing Derevi.
When Derevi dies, its persist ability triggers, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
When Derevi enters the battlefield, it triggers, untapping Cauldron of Souls.
Activate Thermopod by sacrificing Aerith.
When Aerith dies, it triggers twice.
Resolve Aerith's persist trigger, returning it from your graveyard to the battlefield with a -1/-1 counter on it.
Resolve the second Aerith trigger, putting a +1/+1 counter on each legendary creature you control, thus removing the -1/-1 counters from Aerith and Derevi.
Repeat.
