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

He went straight to the point, requesting access to all the technology related to the Su-47 Golden Eagle.

Perhaps this is already common knowledge to most of you.

The Su-47 is a fighter jet that failed its validation tests and never entered active service.

Its defining issues revolved around its groundbreaking forward-swept wing design, which presented two seemingly insurmountable challenges - wingtip flutter and aerodynamic divergence.

These two problems remain unsolved mysteries in current scientific and technological realms.

Even though the forward-swept wing design offers numerous advantages, its viability is rendered moot in the face of these two unresolved problems.

At supersonic speeds, it's highly prone to structural failure - a well-known fact.

However, many may not be aware of the Su-47 Golden Eagle's development background.
