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

A chain of bullets exited the muzzle of the gun.

It wasn't an exaggeration; he really felt numb.

His ears were ringing and his hands were a bit numb too.

When he turned around, he saw Lin Chao behind him already wearing earmuffs.

"Darn! Why didn't you give me one?" Tang Rui shouted.

"Speak softly," Lin Chao laughed and replied.

"Come sit down and rest for a while; you'll be fine in a moment."

After a while, Tang Rui began to feel more comfortable, at least his ears weren't ringing anymore.

"Feels good, doesn't it?" Lin Chao asked Tang Rui, inquiring about his shooting experience.

"Absolutely," Tang Rui nodded. This feeling of firing with such firepower was truly exhilarating, especially since the targets in front had already been riddled with bullets.

"Definitely. I want to play until I'm exhausted today."

It Feels Good, But It Hurts
