Domain: From the Start, I Get the Demon Lord’s Divine Domain

The devastating earthquakes destroying cities are actually caused by the revival of ancient beasts from the Classic of Mountains and Seas! Hidden in mysterious, dangerous forbidden zones are passages to sub-universes! The world-shattering tsunamis battering the coasts are caused by disaster-level monsters sneaking across the border! The ancient Heaven-Reaching Tower, off-limits at a famous tourist attraction, is actually a mythical tower that appeared out of nowhere in antiquity! The awakening of domains, the bonds of genetic locks, the ocean of the mind... Can humanity surpass its own limits? With the invasion of the insect race, demons, and dragons, where will humanity turn as the darkness of the apocalypse closes in?
