"Boom...rumble rumble rumble..."

As the biggest obstacle that once stood in the way of supersonic passenger jets, the disruptive effect of shockwaves was incredibly strong; they could be heard breaking the sound barrier from ten kilometers away, creating a tremendous noise.

However, for the citizens of Rong City, this had become somewhat commonplace. Not to mention the presence of Airworthiness Manufacture, which led to frequent loud noises from the sky, but after New Yuan's arrival, the frequency of the noise almost doubled.

The jets from the flight school, the aero-space planes heading back to base for parts replacement and maintenance, New Yuan's own C810 aircraft frames – they were all continuous sources of shockwaves. The quickly-adapted citizens hardly bothered to look up at the sound anymore.

This even became a major way to tell if someone was a local or not; anyone who looked up intently into the sky definitely hadn't been in Rong City for long.
