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.

My Items Have an Upgrade Panel

Tonight, the planes on combat duty had already taken off.

However, the control tower had not received any notice of the night patrol mission or a transfer request.

Where did the plane need to take off?

He accessed the system. The aircraft model remained unknown, all other information was classified, and the identification code was correct. But the location... Where on earth was this?

Was there even an airport in Jiangbei District?

The tower relayed the information to the higher-ups for approval.

Why would such an unknown classified aircraft model request takeoff from them?

Logically, shouldn't they be at a secret airport?

But the issue was... There was no problem with the other party's identification code.

Tower: Such Grievance is Unacceptable
