I Can Summon Infinite Armies

After sixty years clawing through a nightmare wasteland, an elderly transmigrator receives a system that can spawn endless troops—just as death comes knocking. Evil gods whisper corruption to humanity. Ghouls feast in the ruins. Ancient bloodlines lurk behind mortal faces. Abyssal trolls, jungle horrors, and eldritch nightmares all bow before one truth: the dark age ends not with heroes, but with an unstoppable tide of metal and firepower.
