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

Tang Rui and Professor Li entered a huge underground space.

Upon entering, a massive aircraft greeted their eyes.

I'm not using the adjective incorrectly; it's truly massive.

"This is the second validation prototype, with a length of 38.42 meters, a height of 12.25 meters, a wingspan of 27.15 meters, a fuselage diameter of 7.2 meters, a maximum takeoff weight of 122 tons, and a return landing weight of 92 tons."

Professor Li casually stated the parameters of this aircraft.

As the chief designer, he knew every performance parameter of this aircraft like the back of his hand.

"What kind of fuel does it use?" Tang Rui asked, looking at the rocket engines at the rear of the aircraft.

"Can I see the detailed specifications of the engine?"

After saying this, Professor Li had someone bring a computer over.
