But before these extraordinary fighters came, they underwent special tuning, sacrificing endurance to greatly enhance their flight speed.
In a short time, they can even maintain a speed over seven times faster than sound!
This gave the Red Qilin Army a feeling of helplessness, like using a cannon to shoot mosquitoes.
If it were just this, the Red Qilin Army could completely ignore these fighters, as the artillery attacks pose no real threat to the military formation.
However, from time to time, an attack from a Duke-level strong person would be launched from these fighters.
Altogether, there have been over forty Dukes who have acted from the fighter group!
This number is roughly all the Dukes currently remaining in the Seven Western Countries!
Twelve or thirteen Great Grandmasters, good at cooperating, are enough to threaten a peak strong person.
