After handing it over to the system, the three brothers knelt down and begged for forgiveness

Nan Qiao became more and more excited as he spoke, and kept gesturing with his hands, as if he was back in that fierce battlefield.

Zhao Gang looked at Nan Qiao and shook his head helplessly, but a barely perceptible smile appeared at the corner of his mouth.

Nan Qiao was excitedly sharing today's "feat" of fighting with Lin Yue and Zhao Gang, when suddenly, a crisp text message alert tone came from her mobile phone.

She picked up her phone to check it, her eyes widened instantly, and a look of surprise appeared on her face.

The text message showed a bank deposit notification. She looked closely and found that it was a salary message.

It clearly stated that her basic salary was five thousand.

Immediately afterwards, two more text messages came in, each showing an income of 100,000.

Nan Qiao opened her mouth in shock, totally unable to believe her eyes.

She quickly looked up at Zhao Gang and asked anxiously, "Uncle Zhao Gang, what are these two hundred thousand?"

Zhao Gang looked at Nan Qiao's curious eyes, smiled slightly, and patiently explained, "This is the reward for your two trips across the other world and bringing back research products."

"You have made great contributions to the country and this is the reward you deserve."

After hearing what Zhao Gang said, Nan Qiao danced with joy.

A huge smile graced her face and her eyes sparkled with excitement.

"I have never received so much money. This is the regular hard-earned money given to me by the country!" she said excitedly, her heart filled with joy and pride.

At this moment, Nan Qiao seemed to see countless bright futures beckoning to her. She secretly made up her mind to work harder in the future and make more contributions to the country.

Zhao Gang smiled and nodded. "The monthly exam is over. This weekend, you should focus on your research on the nano-repair machine with Professor Jiang. The Global Youth Invention and Creation Competition will begin next week."

"Yes, I know Uncle Zhao Gang." Nan Qiao nodded obediently.

The next day, Saturday, Nan Qiao followed Zhao Gang to the headquarters of the Special Bureau and began to follow Professor Jiang in experimental research in the laboratory.

At the same time, Lan Xuxue also took her little invention to Peking University to seek advice from senior students majoring in electronic information engineering and mechanical engineering.

Lan Xuxue's invention is a smart, eco-friendly trash can. Small and exquisite, it's cylindrical in shape and features a refreshing light blue body, perfectly complementing the concept of environmental protection.

There is a solar panel on the top of the trash can, which can absorb solar energy and convert it into electricity to provide energy for the various functions of the trash can.

On the side of the trash can, there is a touch screen that can display information such as the capacity of the trash can, the type of garbage loaded, and the remaining space.

The biggest feature of this smart and environmentally friendly trash can is its automatic sorting function.

When people throw garbage into the trash can, the built-in sensor will automatically detect the type of garbage and put the garbage into different storage areas through mechanical devices.

For example, recyclables are placed in a dedicated area, and hazardous waste is stored separately for later specialized processing.

Lan Xuxue brought this little invention to Peking University and sought advice from senior students majoring in electronic information engineering and mechanical engineering.

The seniors showed great interest in her little invention.

In the laboratory of Peking University, Lan Xuxue looked at her seniors with great anticipation, hoping to get more suggestions for improvement from them so that her little invention could stand out in the Global Youth Invention Competition.

A short-haired senior student pushed her glasses up on her nose, frowned slightly and said, "Your idea for this smart environmentally friendly trash can is great, but it has some minor drawbacks."

"For example, this touch screen may be affected by direct sunlight outdoors, resulting in unclear display and affecting the user experience."

"Also, although the appearance of the trash can is small and exquisite, it may not be very stable and can be easily blown over by the wind or damaged by external impact."

After hearing what her senior said, Lan Xuxue's smile froze slightly and she felt a little unhappy.

She immediately retorted, "I've specially treated this touch screen so it won't be affected by direct sunlight."

"Also, I've designed a weighted device at the bottom of the trash can so it won't be easily blown over by the wind or damaged by external forces."

At this moment, another tall senior student quickly spoke up, "Xiaoxue, don't listen to her. Your invention is amazing! This smart, eco-friendly trash can is not only beautiful in appearance, but also very powerful in function."

"The automatic sorting function is incredibly practical and can greatly improve the efficiency of waste disposal. I believe this invention will definitely achieve good results in the competition."

After hearing the praise from her senior, Lan Xuxue showed a proud smile on her face again.

She rolled her eyes at the senior and said, "Senior, you have good vision. There will definitely be no problem with my invention. I will solve those minor problems before the competition."

Looking at Lan Xuxue's smug expression, the senior student couldn't help but speak again: "Lan Xuxue, your invention is indeed creative, but there is a fatal flaw that you must pay attention to."

"Although the automatic sorting function of this trash can is advanced, it relies entirely on built-in sensors to detect the type of trash."

"Let's not even talk about the sensor's fault tolerance. If the sensor fails or misjudges, it will lead to misclassification of garbage and may even cause more serious environmental pollution problems."

"Moreover, once a problem occurs with the sensor, it may be very troublesome to repair it, and may even require professional operation, which will cause great inconvenience in actual use."

Lan Xuxue's expression instantly turned ugly. She bit her lip and retorted again, "How could it possibly fail so easily? I'm using high-quality sensors, there won't be any problems."

The senior student insisted, "Any equipment has the potential to malfunction. You can't ignore this potential risk just because it seems to be working fine now. During the competition, the judges will definitely take these issues into consideration during actual use."

Lan Xuxue was speechless for a moment. She felt angry and a little flustered. She didn't know how to respond to her senior's criticism.

Seeing this, the senior student next to him quickly interrupted and said, "Xiaoxue, don't listen to her. Your invention is so good, the judges will definitely see its advantages and won't reject it because of such a small problem."

"Besides, even if there is a malfunction, we can still find a way to solve it."

Lan Xuxue nodded and said confidently, "You're right. My automatic sorting trash can has not had any problems since it was invented and tested."

"I don't think it would go wrong that easily. If it was going to go wrong, it would have happened a long time ago, right, senior?"
