Humans aged 15–50 across the globe are suddenly transported and thrown into the perilous Celestial Slaughter World, a realm overrun by Vicious Beasts. Only by reaching Level 10 within seven days can they survive. Kael, a young man from the Dragon Nation, awakens the SSSSS-Rank Talent "Endless Extraction," allowing him to seize talents and attributes from Vicious Beasts and the dead. By looting spoils, he rapidly grows stronger. With this power, he unlocks abilities such as the Eye of Truth, Fire Manipulation, and more. He gathers legendary gear, stacks buffs, takes on mutated Vicious Beasts in solo combat, wins international Resource Wagers, unlocks hidden classes, and rises to become the strongest player. In this great cataclysm concerning humanity's survival, Kael leads his compatriots in hunting Vicious Beasts and competing for resources. With the power of Endless Extraction, he cleaves through the darkness, opening a path of hope for Terra's self-redemption.
