An alien race invaded the Earth on June 6, 2128. At the midst of this war, many nations allied with the alien threat and the war nearly wiped out the rebelling humans of the planet. At the edge of mankind's survival, the United Nations Army launched its forces to eliminate the immediate stellar threats that loomed over Earth.

General Seeker Carlean, commander and leader of the mission, risked and gave his life to destroy the immediate stellar threat. The battle was won though Earth lay in ruins. Perhaps mankind will live to see a few years of peace before the alien threat returns to wipe out their existence.

At the immediate aftermath of the stellar battle, the fallen Seeker Carlean awakens and finds himself at aged 17, living the peaceful life he lived 16 years before he died.

So begins a new game in the battle for humanity's survival.

The Age of Gods has long since ended, their voices no longer heard on the continent of Douluo. Humanity, standing on the shoulders of legends from its history, advanced soul technology to inconceivable heights. The humans of Douluo invented weapons of mass destruction, mechanized armor, and living metals. With these advancements, they went on to conquer the oceans and discovered two new continents. To fuel these new technologies, humanity hunted the soul beasts to the very brink of extinction.

Once the dominant force of Douluo, the few surviving soul beasts now hide in the darkest recesses of their last sanctuary. The weakest have all been hunted, leaving only the strongest to scheme in the heart of the forest. The soul beasts, not willing to fade away, plot an uprising for their survival. In the midst of this, a god from a long forgotten era awakens in the depths of the Great Star Dou Forest to seek vengeance for the soul beasts.

As darkness encroaches from the abyss, hope is found in a young boy who holds a power beyond divinity within himself—Tang Wulin! Hope for both humanity and the soul beasts, as the bridge between the two. He finds his way into the fabled halls of Shrek Academy, where he learns to wield his prodigious powers, makes friends and finds allies, eventually rising to become a towering leader.

As he learns to harness his strength, danger lurks within the shadows as the various factions of humanity maneuver and plot to usurp Shrek Academy. Tang Wulin discovers the threat to the only world he knows as he sinks deeper into the intrigue. Meanwhile, camouflaged by the chaos and unbeknownst to the humans, the soul beasts’ plot continues to steadily advance.

To defend what he loves and reclaim what was lost, Tang Wulin must seek out the legacies of legends past and unlock the full might of the Golden Dragon King!

Violet skies, a world undergoing massive changes, a deficient moon, interlinking voids…
When the world experienced a cataclysmic event,the majority of living things ceased to exist. Although humanity survived by hiding in the last safe zones, humans had to face mutated dire beasts and colossal source beasts that could break through the space barrier and enter the earth at any second.
Luo Yunyang, a young man who grew up in those calamitous times, obtained an attribute regulator and set out to walk the path of supremacy!
