Thrown into the chaotic “god Verse,” Ryan Stone awakens a power beyond imagining: the SSS-Tier “Ultimate Infinite Extraction System.” While others struggle with mundane abilities, Ryan can deconstruct anything, from monster corpses to ancient artifacts, even the fading signatures of defeated foes, assimilating their essence to achieve limitless growth.From a desperate survivor in a starting outpost, Ryan’s unique talent propels him to unimaginable heights. He outwits cunning rivals, crushes powerful challengers in Sector-wide scrambles, and seizes control of a god Weaver, becoming a Sector Lord. But as he unravels the secrets of the lost Precursors and the cataclysmic Reality Schism that shattered their universe, his system evolves, granting him the power not just to extract, but to impose his will on reality itself.

A failed investor from 2017 got drunk and woke up in the 1980s. China is just opening up, and the economy is blooming. There is also the dissolution of the Soviet Union, the bursting of the Dot-com bubble and other financial crisis. He used his knowledge of the future and slowly build up his empire.

William and his college class are ripped from Earth and thrown into Aethel, a world on the brink of collapse. Everyone gains incredible magical powers – except William. Mocked and underestimated, he’s an outcast among heroes. But William has a secret: an SSS-ranked skill that lets him travel to Aethel’s past. Learning lost magic from ancient masters, he’ll surpass his classmates and become the true savior Aethel needs. But can he overcome the dangers of the past and present to forge his own destiny? While others studied about the first mage, William could go back in time and see the first mage himself! While others dreamed of seeing a dragon, William could go back in time, hatch a legendary dragon egg and turn it into his puppy. While others used common materials to craft their items, William could go back in time and mine materials that weren’t find anywhere in Aethel anymore. Is it unfair? Perhaps, but William was not the type of person to not use the powers the universe gave him.
