Billions in my Space：King of the ApocalypseEpisode 4

After giving everything to his fiancée Chloe, Gage is betrayed, murdered, and robbed of the Core that grants him power—only to awaken three days before civilization collapses under lethal heat and a zombie outbreak. Armed with his memories and a limitless storage space, he hoards supplies, fortifies a private stronghold, hunts Cores to evolve his abilities, and rescues Evelyn, the fire-wielding woman who once saved him—turning the apocalypse into a second chance for revenge, power.
