Mu Yuan accidentally obtained the qualification for a mysterious game which mirrors the real world. In this game, players could recruit troops, establish territories, and even manifest items from the game into reality.
His game started with ten Little Skeletons, but...
Little Skeleton→Skeleton Soldier→Skeleton Warrior→Skeleton General.....→ King of Skeleton
"What if I evolve the Little Skeleton into an Emperor of Skeletons? How would you respond to that?"
"Evolution Points, let's see what your limit is!"
Several years later, when the worlds overlapped, Mu Yuan, amidst a throng of gods and demons, had ascended to the extreme peak.
