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

"Senior Brother, Brother Liu, I don't think I'm selling cheap, am I?

"The American spring-loaded knife is only selling for $6000 USD each," Tang Rui said in exasperation.

Although his product's performance is definitely better than an American spring-loaded knife, the cost is much cheaper.

The selling price is four times that of the spring-loaded knife; it can't be considered cheap.

"Too small, your perspective is too narrow.

"Let's have a drink and let Brother Liu explain it to you.

"Don't underestimate Brother Liu; even though he's not tech-savvy, he graduated from the International Relations School, understand?"

Wang Yuan patted Tang Rui's shoulder and sighed.

An international relations graduate?

Now that was definitely impressive.

Tang Rui picked up a glass of alcohol and drank it directly.

"Brother Liu, teach your junior here."

Liu Yu glanced at Wang Yuan and turned to Tang Rui.
