Worldwide Survival: Begins As An Island Owner - Chapter 15

Memories shape who we are—they define us, anchoring us to our pasts. They are like videos, playing endlessly in our minds.But everything changed one day when people began to relive their memories. However, it wasn’t the pleasant ones that resurfaced. Instead, they were forced to experience their worst moments—or even memories that weren’t their own.Those who managed to survive this haunting experience found themselves watched by strange creatures, and in turn, were granted their powers.As if the world weren’t already thrown into chaos, these same bizarre monsters began to manifest on Earth, threatening humanity with the very real prospect of extinction.Amidst this upheaval, a small, seemingly insignificant beast was born. But it quickly rose to power, only to be betrayed and killed in a cruel twist of fate. Or so it seemed—because somehow, the beast found itself reborn in the body of a human.
