It's worth mentioning Levi's "Shadow Dragon Group" talent.
After reaching the sixth-circle, his upper limit had reached three thousand!
Now was a great opportunity to replenish his forces.
Three thousand from the Black Shadow Army, even though they were all level 4,
formed a combat array that was astonishingly powerful.
Not to mention, there were plenty of elite level 5 shadows within it.
In fact, if Levi used "Red Emperor Domain" or "Fire Dragon Tribulation" to kill the black beasts, he would achieve the highest efficiency.
But doing so would reduce the black beasts to ash, completely wasting their corpses.
Therefore, he chose to use cold weapons, attacking flesh-to-flesh, killing the black beasts while simultaneously honing his combat skills.
Currently, among the Barbarian King battle techniques he had learned,
he had cultivated the "Lion King Battle Technique" to the Perfection realm, achieving a level that even its creator could not surpass in his lifetime.
