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

"How could this happen? The senior from Kyoto University clearly checked it and said there was nothing wrong..."

At this moment, the machine suddenly made a loud "bang" sound, emitted a cloud of black smoke, and completely stopped working.

Lan Xuxue stood there blankly, looking at the messy display stand and the mocking and gloating audience. She knew that her competition had been completely messed up.

In the end, Lan Xuxue was asked to leave the stage with a score of 0, the lowest score in history.

Lan Xuxue walked backstage in a daze. As soon as she entered, the noisy surroundings suddenly quieted down a bit, and then a series of cold and gossipy glances were cast at her.

When Lin Yue saw her, the corners of his mouth rose slightly, revealing a sneer with undisguised sarcasm in his smile.

She crossed her arms and tilted her head slightly, as if to say, "I knew this day would come for you."

Nan Qiao sat aside and just glanced at Lan Xuxue lightly without much reaction. He thought to himself that she was too arrogant in her daily life and deserved the fate she had now.

She quickly looked away and continued doing her own thing.

The others also pretended to look at Lan Xuxue casually, with disdain and curiosity in their eyes, but more of indifference.

No one came forward to comfort her. The air seemed to have frozen. Only Lan Xuxue's heavy breathing and the faint laughter of the crowd echoed in the background.

She stood there, feeling like a loser abandoned by the world.

Lan Xuxue never thought that she, the daughter of the Lan family, had always had smooth sailing and had never encountered any setbacks since childhood, but today she would suffer such a great humiliation!

Her eyes were red, and she appeared calm on the surface, but her heart was in turmoil.

Next it was finally Nan Qiao's turn to play.

Nan Qiao confidently walked onto the stage with the first generation of nano-repair machines, her eyes firm and bright.

She placed the repaired machine on the display table and began to explain its principles and functions in an orderly manner.

The judges in the audience listened attentively, with scrutiny and expectation in their eyes.

After the explanation, one of the judges frowned slightly and asked, "You said this repair machine has such miraculous effects, but how do you prove it?"

Nan Qiao did not hesitate and reached out to pick up the knife beside her. Just as she was about to cut herself for the experiment, suddenly, Lin Yue hurried out from backstage.

Lin Yue's face was calm. She walked a few steps to Nan Qiao's side. Under everyone's astonished gaze, she quickly snatched the knife from Nan Qiao's hand and cut a cut on her own hand.

Blood gushed out instantly, but she remained calm, as if she was not the one injured. She extended her hand to Nan Qiao and said, "Try with my hand."

She looked straight at Nan Qiao with a soothing and firm expression.

The audience was suddenly in an uproar, and everyone's attention was focused on the two people on the stage.

Nan Qiao looked at Lin Yue's injured hand, was stunned for a moment, then took a deep breath, and prepared to start the experiment with the first generation of nano-repair machine.

Nan Qiao quickly adjusted his state and aimed the port of the nano-repair machine at Lin Yue's injured hand.

The machine made a slight humming sound, and a soft blue light shot out from the machine, covering Lin Yue's wound.

The audience held their breath, and the judges leaned forward, staring at the stage without blinking.

The number of media outlets holding cameras and filming videos had doubled at some point, and all the cameras were focused on Nan Qiao.

Lin Yue appeared calm on the surface, but she was a little nervous inside. She was very excited to test the nano-repair machine for the first time.

As time passed, the wound gradually changed.

The blood flow seemed to slow down, and a tiny light began to flicker at the edge of the wound. That was the nanoparticles taking effect.

Lin Yue could feel a slight tingling sensation coming from the wound. She was delighted and started!

There were whispers in the audience, and some people were wondering whether the experiment would be successful.

Suddenly, the wound began to heal at a speed visible to the naked eye. The scratch first stopped bleeding, and then the damaged skin began to slowly close, as if an invisible hand was carefully stitching it together.

The judges showed surprised expressions, and the audience couldn't help but exclaim in surprise.

"Oh my god, there is such a magical machine. The wound really healed instantly!"

"This is the legendary thing. The wound has healed before we even get to the hospital!"

"I have no regrets in my life as I have been able to see the launch of such a high-tech product!"

……

Nan Qiao breathed a sigh of relief and a confident smile appeared on his face.

After the experiment, Nan Qiao politely bowed to the judges and the audience to express his gratitude.

There was warm applause from the audience. This wonderful demonstration left everyone impressed with the nano-repair machine.

As soon as Lan Hanwen stepped into the competition venue, he was attracted by the scene on the stage.

He saw Nan Qiao operating the nano-repair machine calmly. He was shocked by the focused expression and the technological light emitted by the machine.

His pace slowed down involuntarily, and he stared at the stage without blinking, his heart full of disbelief.

Nano repair machine, isn't this exactly what he's looking for!

It’s actually related to Nan Qiao!

He never thought that this sister, with whom he had long lost contact, would one day become a great help to him.

After the shock, an irrepressible excitement surged in his heart.

He quickly began to think in his mind that if he could use this nano-repair machine in the future, it would bring him endless wealth and fame.

Although he and Nan Qiao had severed their relationship, at this moment, it seemed insignificant in the face of interests.

Lan Hanwen gently pushed up his glasses on the bridge of his nose, revealing a dark glint in his eyes that was determined to win.

He thought to himself, "She is my biological sister after all. Blood is thicker than water. As long as I talk to her nicely, she should agree to give me the patent rights."

His eyes revealed eagerness and greed, and his fingers trembled slightly unconsciously.

He stood there, watching Nan Qiao accepting everyone's praise and applause on the stage, feeling mixed emotions.

I felt a little proud of my sister's success, but also a little embarrassed that I was about to ask her for help.

But when he thought of the huge benefits that the patent rights would bring, he gritted his teeth and decided to talk to Nan Qiao after she stepped down.

After the judges murmured among themselves for a while, a judge with gray hair and sharp eyes spoke first: "Ms. Nan Qiao, your nano-repair machine was very effective in the demonstration just now, but we are wondering if the nanoparticles it uses will pose any potential health risks after long-term contact with the human body?"

Nan Qiao raised her chin slightly, her eyes firm and confident, and replied calmly, "Dear judges, we have fully considered this during the research and development process."

"The nanoparticles we use are biocompatible materials that have been specially processed and rigorously screened. Simulation experiments and animal tests have shown no negative health effects."

"During the repair process, these nanoparticles will be automatically excreted from the body after completing their task and will not remain in the body."

"Also, this is just a trial product in the initial stage. If it is to be widely promoted in the future, we will continue to test and update it."
