Apache didn't slow down. As he increased his speed, his movement had drawn the air away from the center and created a wind wall around Patroclus.
When Apache finally reached the limit of his speed, the space in the middle of the circle had become a complete vacuum. By then, if Patroclus wished to break through the encirclement, it would already be too late.
As the wind wall shrunk in size, a tornado appeared at the center. Suddenly, a glint appeared above Patroclus's head that was unmistakably steel.
It was Apache's coup de grace—Vacuum Tornado!
Apache wagered that Patroclus would allow him time to deliver his coup de grace due to the Ivantian's personality. However, once Apache's coup de grace was released, he doubted if Patroclus would be able to counter it.
