The rumbling lasted only for a few seconds before quickly fading.
Nangong Ruiyang and others thought it was due to engine shutoff, but they saw the pale blue flame still existed, becoming slimmer, the continuous muffled roar of airflow.
The Crystal Jet, derived from design plans not long ago, slid all the way from the tarmac to the start of the main runway, with the large delta wings' rear segment rising symmetrical upper and lower tail fins, forming an X-shaped fully movable tail.
The wing surface of the large delta wings faintly revealed scale-like overlapping patterns.
Bang!~
A muffled thunder arose from the ground, and the Crystal Jet that completed its final takeoff preparation suddenly accelerated, lifting its nose at 50 meters of sliding, directly vertical ascending.
