"Altitude 700, speed 535!"
"Altitude 1100, speed 710!"

Lei Qing had taken off and turned 90 degrees towards Yinchuan, beginning to steadily climb with the aircraft.
He wasn't in a hurry to turn on the afterburners, maintaining military thrust to keep accelerating until he reached 5,000 meters and broke the sound barrier before testing the top speed.
In the mystery of supersonic flight, the factor of the engine isn't as significant as the design of the aircraft itself. A good airframe shape that matches the optimal working range of the engine is the key focus of design, but this often requires compromises with avionics equipment and weapons bays, needing precise control over the balance.
The 62-ton aircraft surprisingly felt light to handle, and the climbing speed was incredibly fast. Just 3 minutes after takeoff, it had already reached an altitude of five kilometers and had just broken the sound barrier.
