In a world ravaged by ruin, where the land is lifeless, skies are smothered by dust, and sunlight no longer graces the earth, survival is a battle against insurmountable odds.

The remaining humans are caught in the grip of a merciless, dying world.Amidst this desolation, Mu Liang awakens a unique and extraordinary gift: the power to absorb energy and evolve. This ability allows him to transcend the limits of nature, unlocking endless possibilities for the world around him to evolve.A humble sapling, infused with the power of evolution, grows into a towering World Tree that blots out the sky. A small land turtle undergoes an unimaginable transformation, evolving into a mighty, world-bearing creature. A tiny spider? It evolves into a malevolent being, capable of manipulating the threads of fate.With the immense strength of a continent-sized tortoise and the power to command the weather through the World Tree, Mu Liang stands poised to create his own kingdom—a world of limitless evolution, where nothing is beyond his reach.This is the story of a man who, in a shattered world, harnesses the power to rewrite fate itself.

Billions of people around the world were transmigrated to the game world of “Shining Era.” Everyone became lords and possessed their own land.

They recruited troops, gathered resources, occupied mines, attacked cities and built up their empires.

In this world of lords, the most important resource was the troop lairs where they could recruit troops.

However, the potential of these lairs was fixed. If anyone wanted to obtain a top-level troop, they could only do so by defeating powerful wild troops and occupying their lairs.

However, Richard discovered that he could actually improve the level of troop lairs directly.

From then on, various powerful troops were groomed by him.

When the other players were still leaping with joy from obtaining a high-level troop, behind Richard were a Desert Pharoah, a Demonic Scorpion King, a Mechanical Giant, a Demon Baron, a Blood Archduke, a Five-colored Evil Dragon, and a Fallen Angel.

From that day on, a prosperous and dazzling oasis city was established in the desert. As for Richard, he became the ruler of the desert.
