MoPako System

In the world of Junosa, monsters that had predated civilization exists beneath the soils humanity walks on. The Dungeon. A fathomless place where these dangerous creatures ran amok. For centuries, humanity ventured out the outlandish underworld, hoping to put a wall between their worlds, and perhaps bring stories of conquest and glory. Monster hunters with their gifted ability from the gods called Tezhe, were able to contend with the monsters, bringing harmony and progress upon their world. Every decade, however, a new wave of monster outbreak would ascend the dungeon boundary and lay havoc on their lands. For Mettel, a normal boy living on the surface–the monsters was a far off dream. However, when the White Void, the Hydra Ithivora, destroyed his village by passing, everything in his life had changed. With a miracle, he'd survived. But it wasn't the end of it–one day, a transparent rectangular box magically appeared in his vision.

Within the dark deep dungeons, a helpless worker bee was born. His name was Robert, he was sure he was still sleeping but what are these words popping up in front of his view like game-system prompts? MoPako System? Species name: Mel Apis Infans? Also why does his body feel... weird? The last thing he remembered was conversing with a certain prophet. Said something like being reborn and hoping for me to have a good life. Now what in the hell is this? Why is a monstrous humongous worker bee being eaten by an even more monstrous massive centipede?!?

In the embrace of the shadow depths, an egg buried within the sand cracked to reveal a hatchling spider. "Huh, where am I? Where is this? Cough!" It's so goddamn dark in this place! Ow. She hit her head. What are her legs sticking onto? Wait, eight legs? Then a message prompt appeared in front of her, the MoPako System. Species name: Misumena Dumu. Skills: Webbing, Bite, Grasp. Then there were the creepy scene of other eggs the size of half an adult cracking only for equally as big colorful spiders to come out. Sadly, she just has to look up to see an all-pervading fog consuming them as they disappeared to nothingness. Okay, starting out big aren't we? A monstrous entity hidden in the fog that's likely beyond my imagination, check. Time to run.
