The Evil God Descends, I Own Great Hell

As the apocalypse unfolds, a malevolent deity descends upon Earth, preying upon humanity and endangering my homeland, China. Yet, unbeknownst to these invaders, I command the Demon-Suppressing Hell—a prison that has secretly confined countless gods and primordial beasts from Chinese lore for millennia. All was prepared for this very day… to eradicate the foreign gods and purify the world. Should you surrender, as the Warden, I may permit you to join the Great Hell workforce—operating sewing machines with meals and lodging included.
