Lord of All: My Troops Can Be Upgraded Infinitely

Qingchen traveled to the era of national lords, and competed with tens of billions of blue star lords for hegemony, becoming king and defeating bandits. When other people's random troops at the start are gods, monsters, beasts, dragons and angels. Qingchen's military unit is only the human army, which can be called the lowest military unit. But fortunately, Qingchen awakened the "infinite upgrade" lord talent. So what if it's just the Terran Corps? Have you ever seen a hundred-level, thousand-level, or ten-thousand-level human generals and human legions? I, the human race, should not be weaker than other races! Even immortals!
