In front of the whole world, Yang Fan unleashed a full set of Soul Stealer Three Whips and literally beat a demon to death.
This incident was like a fuse, instantly triggering a major war.
In the border region between the Azik Alliance and the Carmenia Federation, dense howling suddenly erupted in the sky.
It was the emergency sortie of Carmenia Air Force's fully stealth fighter group.
After the Superpower Era arrived, all countries discovered large quantities of supernatural materials. Fighter jets moved from the old radar-stealth era into the full-stealth era.
That is, radar stealth plus optical stealth.
But in terms of performance, Great Xia's fully stealth fighters are significantly ahead of those of other countries on Canglan Star.
Careful observation at this moment shows that several kilometers up, some faintly visible transparent air masses are moving rapidly.
This is precisely the biggest current difficulty of optical stealth.
