My troops evolve infinitely

Maki Yuanou has obtained the qualification to play a mysterious game. The other side of the game is the real world, where players can recruit soldiers, build territories, and also materialize items in the game into reality.
He started with ten little skeletons, but...
Skeleton → Skeleton Soldier → Skeleton Warrior → Skeleton General → Skeleton King
"If I evolve the little skeleton into the Skeleton King, how will you respond?"
"Evolve! Let me see your limits!"
Several years later, when the worlds overlapped, Mu Yuan had already reached the summit surrounded by countless gods and demons.
