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 exered significant effort to drag the two hefty boxes into the living room before proceeding to open one of the boxes, revealing a sit-up fitness machine inside.

Previously, the salesperson who specialized in fitness equipment had inquired about which body areas Tang Rui aimed to target during his workout.

Tang Rui promptly responded, expressing his desire to focus on enhancing the strength of his waist and abdomen.

The other party suggested this particular sit-up fitness machine.

Upon unpacking the box, he took out all the components.

To his surprise, the machine was not pre-assembled; instead, it had been disassembled into panels and parts, requiring him to assemble it himself.

Fortunately, the assembly process turned out to be quite straightforward.

Nonetheless, Tang Rui paid little heed to the complexity of assembly. A new idea had taken root in his mind.
