"By my hand".
It worked just the way it had last time, the scroll unfurling to make a large circle when both its end met, but this time there were some differences.
A circle of over 1000 diameters appeared in the air, blanketing the 100s of men and about 5 catapults, and then with the next instant, that wide circle formed by the scroll was completely filled with fire.
The difference between the qi of 1st stage soldier Seth and 3rd stage soldier Seth was incomparable, and at the moment this attack was being powered by Seth's current qi.
Like an oven had been opened above the sky, the people on the ground were blasted by a wave of still rapidly increasing heat and Seth's uncontrolled aura, and then before they could understand anything more about the situation, a gigantic hand fell out of the circle, boiling the air it passed through and then slamming into the ground.
