The Invincible Tyrant's Rule over the Infinite Universe

He transmigrates to another world and awakens the Tyrant System. Anyone who poses a threat to him gets killed, killed, killed. To the outside world, he is an invincible tyrant. To his own people, he is the kindest emperor. If the army is too small, he can churn out troops. If food runs short, he can churn out grain. With the System's shop at his disposal, all he needs to do is kill, and he will never lack anything. But after ruling over countless universes, he discovers that he is still nothing but an insignificant ant. Unless he transcends the ultimate Dao and becomes ruler of the universe, he will never attain true invincibility.
