Universal Lord: I Have a Modifier

The endless continent is vast and filled with thousands of races. Every human who comes to the Endless Continent will bind a castle, recruit troops, seize resources, and conquer cities and territories. Xu Ze came to the Endless Continent and found that the soldiers he recruited were actually just the most ordinary skeleton soldiers.

"Obviously the full level is level 100, why are these skeleton soldiers reaching level 101?" "Aren't skeleton soldiers of undead nature? Why are they bathed in the holy light?"
