In the tribal farming era, the world was vast and unknown. Upon continuous exploration, the people of ancient times were appalled to discover that in this world, where the sky was round and the earth was square, all sorts of miracles had befallen them. There were even figures like an ultra-big ten-thousand-foot giant, as well as huge intelligent beasts that had mysteriously appeared, trampling upon the mountains and rivers, and shattering the earth. Hundreds of years later, in such a dangerous environment, people fought against the huge beasts and finally established the glorious Sumerian civilization. On this day, a wise giant suddenly made a complete descension on earth, trampling on all the mountains and rivers, and wiping out the entire nation. The world crumbled, and city-states collapsed; had the gods descended to condemn the people?

Then, I will shepherd the human race and various worlds in my sandbox.

"Locke transmigrated into an era where everyone had Battle Beasts. Daemons were rampant and humans were forced to build walls around their dwellings while depending on Beastmasters to keep those monsters at bay.
