Wolfberry is not Tasty

As a video uploader who owned a model aircraft online store, Tang Rui suddenly discovered that the model aircraft he made had an upgrade panel that allowed him to add upgrading points to it.

For a couple of hundred yuan, Tang Rui upgraded the body of the aircraft to a proportional level, perfectly replicating the dashboard in the cockpit. He also added some enhancements, turning its EPO body into an aviation-alloy one.
Tang Rui said, "System, show me your limits."
From toy model aircraft to high-altitude, high-speed drones, and then to small-scale orbital shuttles...
With the system panel in his hand, it would be too unambitious of him to just be a video uploader on a small website instead of creating a military weapons company and becoming famous.

At this point, it was time to kick things into high gear. Tang Rui narrowed his eyes and pushed the throttle forward with his left hand. He pushed the throttle all the way in, and in an instant, the drone's engines unleashed a mighty surge of power.

Once the speed reached Mach 4, the air entering the intake had reached the engine's required supercharging speed.

The outer bypass doors swung open, and the supercharger turbine ceased spinning. The engine transitioned from subsonic to supersonic combustion, and the acceleration continued.

As both drones reached a speed of Mach 6, the difference in engines became apparent. The one with system-enhanced control continued to accelerate aggressively, while the other, lacking the enhancement, began to lose acceleration, albeit still gaining speed, but not as rapidly.
