They were so engaged in their conversation that they didn't notice Professor Qian bringing Qian Xuanxuan into the private room after Tang Nan's departure.

  Qian Xuanxuan finally noticed him and shook off Professor Qian's hand, calling out "Xian Yu sister" as she rushed towards her.

  "He found out that you signed the contract and was making a fuss to come over and congratulate you." Professor Qian explained to Xianyu why he brought Qianwan with him, but still couldn't help it and scolded her: "You young people, your ideological awareness is really too low! If everyone thinks like you, how can this nation be passed down? Won't humanity become extinct?"

  "Yes, Professor Qian, I know I was wrong. I will correct my thoughts and be a good young person who loves the country, the party, and society." But it's just lip service, only she knows what she really thinks in her heart. This is what they mean by "insincere apology" and "failing to change despite repeated warnings".

  Her apology came too easily, so Professor Qian always felt like he had a mouthful of air stuck in his throat, glaring at her for a while before humming and ignoring her as he sat down.

  It's done, teasing the tiger's whiskers. Xianyu and Qian Xiaoxiao exchanged a glance, then under his encouraging gaze, they slowly sat down beside Professor Qian, calmly changing the subject: "Professor Qian, I've been thinking of developing a high-pressure pulse electric shock device lately, but I've encountered some problems in my research. Do you have time to guide me sometime?"

  When it comes to academic research, Professor Qian is easily distracted and forgets his anger. He turns around and asks her, "What's the point of doing this if you have nothing better to do?"

  "Self-defense, after all, is a weak woman, with some defensive things, and a more peaceful mind."

  Zhou Mei and the other three people who were attracted by this topic immediately understood what she meant when they heard her say this, and it was probably the surprise solution to the winter vacation travel safety problem that she had mentioned.

  "But our country doesn't allow carrying controlled devices, even if you make it, you can't take it on public transportation." They all thought that what I wanted to do was something like an electric baton.

  "So what I'm going to make is a high-voltage pulse electric shock ring, convenient and portable."

  This ring has been popular in the galaxy for a long time, and she happens to know how to make it. The metal used to make this ring is very special, about the size of a fingernail can store a huge amount of electricity, but Earth does not have this metal, so the smallest electric shock devices on the market are as big as a palm, which is not only eye-catching but also inconvenient. If you really get hijacked, the hijacker won't even give you a chance to take out the stun gun.

  "Can I pre-order one after you've developed it, junior sister?"

  "Does Tang Xue also need protection?" He raised an eyebrow in his spare time.

  "Can't I just be buying it for my mother?" This schoolmate is really holding a grudge, he just said her thoughts were a bit dangerous, must she tease him like this?

  "That might require Lady Tong herself to operate it personally, I plan to sell this ring with real-name system."

  Is it a real-name sale? Before Tang Nan could speak, Professor Qian interrupted: "Do you have any other ideas that haven't been said?" Generally, self-defense tools don't require real-name purchases. Have you ever seen anyone buying a knife and needing to register their identity? Only guns and the like need registration. Professor Qian realized that this ring might not be as simple as Tang Nan had said.

  She indeed had something else to say, but now wasn't the time for that. "Are you free? I'll go find you?"

  During their conversation, Wang Meng and others had already arrived. Professor Qian obviously also found that the place and timing were not appropriate, so he nodded and said: "Alright, you come to my office tomorrow to find me."

  She easily changed the subject and settled the matter with Professor Qian, and then let out a quiet sigh of relief. Qian Xun sat beside her and secretly gave her a thumbs up.

  Wang Meng and others who had heard the news halfway were all looking at Xianyu with envy. Just a few days ago, they had just signed the contract for the innovative engine, but now Xianyu already had new ideas again. And Xianyu's strength was evident, although she hadn't researched the ring yet, they somehow felt that it would only be a matter of time before she succeeded.

  Everyone has arrived, so I called the waiter over to order and asked him to add a set of tableware for Qianqian.

  The crowd, without any preparation, opened the menu and was shocked. A plate of tofu costs hundreds of dollars. Is this tofu made of gold? Although they knew that Xian Yu had just signed a contract and must be very rich, being rich doesn't mean you can spend money like this.

  It seems that Professor Qian has seen through everyone's thoughts and smiled: "Don't worry, just vote boldly, your junior sister is not short of this little money."

  Professor Qian's words were like a reassurance pill, and only then did everyone dare to let go of their hands and feet and order the dishes they loved to eat.

  After everyone had finished ordering, the menu was passed to Xianyu. The young people mostly loved spicy food, so they ordered dishes that were heavily seasoned and spicy. Professor Qian probably wanted to cater to everyone's taste, so he only ordered a bowl of soup. Then she ordered two more dishes with light flavors and easy digestion for Professor Qian, and helped Qianqian order a dessert before handing the menu over to the waiter.

  They ordered a lot of dishes and I thought we would have to wait for quite a while before the food arrived, but surprisingly, it only took about ten minutes or so for all the dishes to be served.

  All I can say is that this private house restaurant is expensive for a reason, it's truly flawless except for the price. The taste is delicious beyond words, she thinks it's the best thing she's had since coming over. She decides to make it a point to visit this private house restaurant frequently from now on.

  Everyone was eating and chatting, the atmosphere was very lively. What's strange is that everyone seemed to know Tang Nan Sheng and Qian Xiao Xiao as if they didn't need anyone to introduce them before they could chat familiarly.

  It wasn't until he asked Professor Qian that he found out that when he was busy before, Qian Xuanxuan would often stay in the lab by herself to play, so everyone had already known her. As for Tang Nansheng, he was recommended by his supervisor and usually helped him sort out some legal matters, and he paid according to the market price of a lawyer.

  He nodded calmly and naturally, no wonder he was summoned by Professor Qian with just one phone call last time.

  Because the dishes were really delicious, everyone had a great time eating. In the meantime, they also drank some wine. After getting drunk and full, they thanked each other for the leftovers and dispersed. Tang Nan was still busy with school matters, so he returned to school early.

  Concerned about the safety of Professor Qian and Qian Weiwei on their way back, Xian Yu and Zhou Mei decided to send them back first before returning to school. Although the four girls may not be much safer either, they are still much better off than this old man and young girl.

  After sending the person away, Qian Wanwan pulled her hand and motioned for her to squat down, saying: "Congratulations, Xian Yu sister, on getting a huge sum of money today." With a milky voice, she said it and then gave her a quick peck on the cheek, after which she ran away with a blush, making the other three people extremely jealous.

  To know that Qian Xuanxuan used to dislike even being touched by others, now he actually took the initiative to kiss her, she only felt that her heart was melted by this little guy.
