Raising Troops by Slaying Enemies: From Abandoned Son at the Border to Supreme Emperor

Xu An transmigrates to the Great Zhou and becomes a pawn abandoned by the Marquis of Might and Valor's household, sent to die on the frontier. He obtains the Conquest System, which lets him raise troops by killing enemies and gain skills.

The vassal kings carve up the land and command millions of elite soldiers?

I'll flatten you, and your territory and your millions of soldiers will be mine!

The great clans monopolize the literary tradition. Without you, government orders can't be carried out, and the realm can't be ruled?

From elementary school graduates to professors, I have soldiers with every level of education. Take your pick.

The foreign tribes are eyeing the Central Plains, ready to seize it?

Once I've raised an iron cavalry of a hundred thousand, I'll give you a six-month head start!

The emperor says I'm a traitor?

Heh!

Whoever loses is the rebel army! You audacious remnants of the previous dynasty, take off My imperial robes!

Years later, Xu An lounges in boredom against the dragon throne.

All under Heaven belongs to the king. This really is dull.

Just then, an urgent report arrives, carried eight hundred li.

"Your Majesty, the Northernmost Protectorate reports that the heavens and earth have undergone a transformation. Mountains collapse and the ground splits. At the fissures, black masses flow like ink, and creatures that are almost, but not quite, human have appeared! We await Your Majesty's decision."
