Above them, storms and lightning roared in unison, but louder than their furious din were the fighter jet engines—and the terrifying cracks as they broke the sound barrier.
Forty fighter jets began their dive, then flew almost skimming the yellow-earth maze. Neither the Fighter Jets nor the Black Blade Fighters flew at top speed. Instead, they kept to around Mach 1.
Once they neared the maze, the jets began rapidly switching between acceleration and deceleration. Dozens of successive sonic-boom clouds appeared at low altitude. Only unmanned, fully mechanical fighter jets could repeatedly break the sound barrier like this; otherwise, their pilots would have been killed long ago.
Even if you put the Hulk in the pilot's seat, an ordinary supersonic fighter couldn't take it.
The most devastating effect of this completely unreasonable flying technique was that half of Hydra's people were literally shaken to death.
The human body was extremely fragile. The deafening booms from those clouds could directly damage people's internal organs and eardrums.
Robots, however, were barely affected by this kind of attack. The combat robots Sarah had made were crude and clumsy, but they were also tough as nails. They had no fear of sonic vibrations.
Hydra had originally turned the tide, using heavy weapons like grenades and the maze's unusual terrain to gradually recover from their disadvantage in a fight where they were outnumbered. But once the fighter jets joined the battle, they were crushed again.
No matter how complicated the maze was, it couldn't stop a sonic attack from the sky.
Luo Xia was very pleased with this tactic. It was much less trouble than throwing bombs around, though only fighter jets made with the AllSpark could pull it off.
En Sabah Nur's face darkened at the sight. He could afford to ignore whether Hydra's
