Silas transmigrated to a world where only a chosen few ever awaken. Those rare individuals are granted the power to step into the Sovereign Realm… a ruthless alternate dimension where Lords carve out territories, construct massive empires, and summon heroes to conquer the unknown.
While most newly awakened Lords grind for basic survival in their desolate starter territories, Silas gets a System that shatters the rules of the game.
[Ding! You have awakened the Absolute Upgrade System.]
With a single thought, he can turn ordinary stone into pure gold and flawlessly enhance every building in his domain.
A starting, bottom-tier 'Red' Lord Core could be instantly upgraded to a supreme 'Gold' Lord Core!
Then comes his very first summon. Instead of basic infantry, Silas pulls an SSS-Rank legendary Goddess summon right out of the gate: Eluned, Former Spirit of the World Tree.
And the summons only get more terrifying. Vespera, the Abyssal Serpent; Aurelia, the Saintess of the Argent Flame; Morwenna, the Phantom Sovereign; Isolde, the Winter Empress; Ariadne, the Lunar Weaver; Thera, the Earth Mother...
As Silas’s unstoppable empire rapidly expands across the Sovereign Realm, rival Lords look upon his battle lines in absolute despair.
Wait... why are ALL of his heroes SSS-Rank?!
