The Human warriors had already retreated to the inner city, so when the Strongarm Bull Devils charged in, they met no resistance.
Just then, in a flash, Ian Song’s figure suddenly appeared ahead.
"Kill him!"
A Strongarm Bull Devil swung his broadsword and charged straight at Ian Song.
With a flick of his formation seal, Ian Song stomped his right foot on the ground and called out, "Absolute Killing Array—activate!"
Instantly, the space ahead twisted, swallowing all the Strongarm Bull Devils who had rushed into the city.
The next wave of Strongarm Bull Devils saw thousands of their companions vanish in an instant and froze in shock, but quickly continued their charge—only to be sucked into the array as well.
Standing within the formation, Ian Song was a bit surprised by this scene—he hadn't expected the Strongarm Bull Devils to be so stubborn. He'd thought he'd need to activate the Illusion Trial Formation to lure in the second wave, but they charged in on their own, saving him a lot of effort.
Now, there were already ten thousand Bull Devils inside the array.
His formation seal shifted again, and instantly, the Bull Devils who had entered the array began slaughtering each other.
At the same time, a third wave—the third batch of Strongarm Bull Devils—continued to charge into the array.
In the blink of an eye, a hundred thousand Bull Devils had rushed into the array, and a wild slaughter broke out among them.
A full hundred thousand vanished without a trace. Only then did the Bull Devil side realize something was wrong and halt their charge.
Seeing this, Ian Song casually formed another seal, and immediately, an Illusion Trial Formation appeared—thousands of "Human warriors" suddenly materialized.
The Bull Devils who had paused couldn't hold back any longer. Shouting, they charged at the "Human warriors," who turned and ran. In no time, the chasing Bull Devils were lured into the array.
After leading thousands more Bull Devils into the array, those Human warriors reappeared at the breach in the city wall.
So, yet more Bull Devils charged at them.
Half an hour later, two hundred thousand Bull Devils had been lured into the array. Of the first hundred thousand to enter, almost all were dead.
A full two hundred thousand vanished without a trace.
This finally alerted the three princes, who personally led thirty Bull Devil Martial Saints to the breach.
