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 widened his eyes, looking at the screen in a bit of confusion.

He had never seen this aircraft before.

But he was certain that this thing was the latest supersonic stealth reconnaissance plane from Yingjiang.

"The shape is different from the disclosed Dawn Goddess."

Using optical systems, it captured the aerodynamic shape and structure of the entire supersonic stealth reconnaissance aircraft.

Tang Rui looked at the 3D model on the screen, his brain calculating rapidly.

Based on the aircraft's characteristics, he pondered for a while and suddenly thought of a Yingjiang prototype.

It was said that this prototype was used for technical reserves and verification in the development of the SR-72.
