Dominating the World After Tomorrow

On the eve of the sun's destruction, the apocalypse arrives. Zombies run rampant, and I have an infinite slave System. The weakest mutant slaves rule the land; the stronger giant Kun rule the seas, while giant Peng slaves dominate the skies worldwide. The even stronger ones roam beneath the Earth's crust. What? Why are you always so focused on my slaves and ignoring me, their master? You should know they're all my slaves! Warning! The protagonist is so powerful that reading this may cause mild discomfort or an intense mental high. Readers with heart conditions or high blood pressure should stay away.
