Zhou Mei grabbed her and wouldn't let her go, "Are you serious?"

  With nothing else to do, he stopped in his tracks. "No, you guys never believe what I say. Am I someone who likes to deceive people?"

  "You clearly know we didn't mean that, and isn't this too surprising?" Zhou Mei explained as she let go.

  She let go and continued her pace with a hint of leisure, "What's so surprising?"

  The three of them hastily followed and said in unison: "Because we think there's still a lot we lack."

  "Moreover, we have no clue about this electric shock ring you mentioned, and don't even know where to start."

  "It's just us three, how can we possibly manage?"

  Finally, he stopped himself and turned around to look at the three of them seriously: "I'm saying when will you three get rid of this lack of confidence? And did I ever say let the three of you complete this task independently?"

  "What do you mean?" the three of them asked weakly, startled by her sudden turn.

  "My intention is that I'm the main force, you three follow and assist, observe more, learn more!" said with a tone of annoyance.

  Learning without applying is useless. How can you just learn and not apply? Only through practice can true knowledge be gained, merely knowing is called being a bookworm.

  She said she would take them to fly, but they also have to dare to jump off the cliff. Which eagle soaring in the sky isn't starting from a leap of faith? If they always lack confidence and don't dare to try, then for their whole lives, they can only become a bird with clipped wings in a cage, gradually losing their will, until even wanting to fly is impossible.

  Xian Yu had never lost his temper in front of them before, but now that he suddenly did, they all became somewhat flustered.

  "Ah, you should have said you were leading the way earlier. We're not that we don't trust ourselves, it's just that we've never actually done this before and didn't know where to start." Zhao Tian stepped forward and held the landlord's hand to ease the tension.

  Knowing that there is a surplus makes them feel at ease, with a surplus, they are not afraid of anything.

  Fortunately, she wasn't really angry, she was just worried that they lacked confidence and couldn't fly freely.

  When the four of them arrived at Professor Qian's office, Professor Qian was facing his computer, busy with something, while Qian Xuanxuan was sitting on a sofa on one side watching a movie. When she saw that they had some free time, she put down her tablet and rushed over. Fortunately, she was well-prepared, otherwise she might have been pounced upon by him.

  "It's just in time that you've come. I've already read your thesis and there's nothing to revise, so you can go back and submit it now."

  The essay written by Xianyu is really good, he has been looking at it for so long and still can't find any mistakes, it looks like it was written by someone who has published many papers. He also had a little curiosity in his heart, but the character of Xianyu made him decide to turn a deaf ear.

  "Do you have any recommendations for which journal?" She wasn't too familiar with these, so she asked Professor Qian first before submitting to some actual ones.

  "The engine you developed is indeed an innovation, but in fact it belongs to the practical application of mechanical engineering technology, with more emphasis on application than theory. So I suggest you submit it to the domestic "Journal of Mechanical Engineering", which has a high gold content and a good chance of being published. If everything goes smoothly, it can be published within two months."

  "Good, thank you Professor Qian." Indeed, having a teacher lead the way is much more convenient than crossing the river by oneself.

  "Don't stand there, sit down and talk, how did you all come here?"

  The four of them sat down, and after casually putting the money in his pocket and sitting it on his lap, he explained: "You also know that last time's project didn't give them a chance to get started, so this time I want to bring them along to do the electric shock ring together."

  I don't know what this little guy eats, it looks thin and small, but its strength is so great.

  Professor Qian nodded slightly, this was something she wanted to do in her free time, and she didn't have the right to interfere with whoever she wanted to bring along, "What was the idea you didn't finish saying yesterday?"

  Finally getting to the point, Professor Qian straightened his back and waited to see if there were any other clever ideas.

  "I want to develop an electric shock ring, only the size of a ring, of course, its small volume is just one of its advantages, it also has a bigger advantage, that is, this ring will be equipped with genetic identification technology and micro-camera technology, each ring will become a customized version."

  A few bystanders pondered for half a day after finishing their leisurely conversation. They understood the small-volume electric shock ring, they also understood gene identification and micro-photography technology, but when these three were combined, they didn't understand what it meant to combine three unrelated technologies.

  Professor Qian seemed to have a bit of an idea, but it was just a vague notion. "You'd better say that again more carefully."

  "It's common knowledge that everyone's fingerprints and genes are different. If we design a genetic unlock ring like a mobile phone, only the wearer can use it, and at the moment of opening, the camera function is also activated simultaneously. Can you imagine how great its effect will be?"

  Of course! It's absolutely possible! Just imagine, if someone is kidnapped by a hijacker and happens to be wearing this ring, they can unexpectedly knock the opponent down and record the facial information of the suspect. How many crimes will be reduced in this world!

  "Can so many things be settled with just one ring? Won't the volume be a bit too small? Moreover, rings have very special meanings, I think it's more suitable to design it as a wristwatch, equally beautiful and convenient to carry." Zhou Mei suggested.

  Xianyu was also considering this issue, she originally thought that only equipping the ring with an electric shock function would be enough, after all, it was just a self-defense tool she designed for their winter vacation trip. However, the more she thought about it, the more she couldn't help but want to add more functions to it. With more functions, the ring's volume became obviously insufficient.

  "Alright, then let's change it to a wristwatch."

  Scientific research is taboo for being self-willed and arbitrary, others have better opinions and ideas, should be humble to accept in order to make progress, so she humbly accepted Zhou Mei's opinion, changing the ring to a wristwatch, actually both are not much different in terms of portability.

  "Perhaps we can also add an automatic alarm function, which will immediately connect with the police once activated."

  "In that case, the tracking and positioning function is also indispensable. After the alarm is triggered, it automatically sends out a location signal, which can help the police quickly find the geographical location of the victim."

  Zhao Tian and Liu Jia also expressed their own ideas.

  This was something she hadn't expected. This electric shock ring was originally designed by a female police officer in the Galactic Union specifically for young children who were unable to resist, and in order to prevent the ring from being exploited by malicious adults, it only had electric shock and genetic identification functions, and could only be sold under real-name registration to children, and others were not allowed to purchase.

  Three smelly shoemakers surpass Zhuge Liang, now everyone has gathered to think and contribute, which has increased its functionality and expanded its scope of application.

  Qian Xuan sat in the midst of leisure, listening to their discussions from left and right, feeling as if her head was spinning.

  Professor Qian listened silently to their heated discussion, feeling only relieved in his heart. With children like them supporting the country's future, what do these old men have to worry about?
