After Tang Jianjun agreed, he opened the toolbox and started working.

On Tang Yuhang's computer screen, the three-dimensional graphics of various parts gradually take shape, each of which is represented by lines of different colors, and then enters six different screens, rotating up and down irregularly.

Grandma Gong and Liang Yuting reported the data to Tang Yuhang after measuring the kitten's various data.

At this time, Tang Yuhang had just completed the design drawings of different parts, and when he heard the data report of Grandma Gong and Liang Yuting, he directly entered it into the computer.

Then he stood up, walked to a white instrument that the other three had never seen, and turned on the display screen lying flat on it, "Senior sister, please help bring the cat over." ”

"Okay." Liang Yuting agreed, picked up the kitten and came to Tang Yuhang.

Grandma Gong and Tang Jianjun didn't know what Tang Yuhang wanted the cat to do at this time, so they raised their heads and looked at Tang Yuhang curiously.

The screen in front of you shows 3D images of different parts, all of which are composed of lines of different colors. Then Tang Yuhang adjusted the data on the side, and the size of each part changed instantly.

Then, Tang Yuhang took the cat from Liang Yuting and held it in his arms, and suddenly said, "Projection." ”

The next moment, Liang Yuting and the three of them were dumbfounded, only to see that the parts on the screen composed of various different lines actually flew out of the screen, still composed of various colored lines, floating above the screen irregularly.

Tang Yuhang ignored the stunned three people and continued: "Assemble." ”

All the parts floating in the air flew towards the middle, and eventually, they combined to form a cat's front legs. The inside of this leg is densely divided into lines of various colors, like a three-dimensional perspective.

Tang Yuhang put the kitten next to the screen, gently lifted the kitten's severed front leg with one hand, and then grabbed the cat's front leg floating in the air with his hand and placed it on the kitten's broken front leg. Then he let go of his hand and carried the kitten's severed front leg up and down a few times with only one hand, and the three-dimensional drawing composed of lines floating in the air also moved with the movement of the broken leg, as if it had really been connected.

"Looks like it's just going to be this size......," he said, looking up at the three who were already stunned, "Huh?" Why do you all have such an expression? ”

Only then did the three of them react, but they still looked shocked, holographic projection. The legendary holographic projection was actually made by Tang Yuhang, and it can be directly controlled by voice......

He is a genius scientist! Liang Yuting sighed in her heart.

"Stinky boy......" Tang Jianjun suddenly scolded, "The holographic projector, it's all made, and I don't know what to tell me, if it weren't for this time, I wouldn't know it yet...... I'll make another one right away and put it in the laboratory of the University of Technology. ”

"Why?" Tang Yuhang shouted, "Grandpa, do you know how much this thing costs?" Just let me send one to the University of Technology for no reason? ”

"Humph!" Tang Jianjun softened his tone when he heard that it might be very expensive, but he still argued, "I'm a professor at the University of Technology, and you grew up with so many professors, so you lost one by sending one?" ”

"I didn't mean that...... Tang Yuhang said helplessly, "That's it, at most half a year, I will definitely change to a bigger one, and donate the current one to the University of Technology when the time comes, okay?" ”

Tang Jianjun just "hummed" and didn't speak again, it seemed that he had already approved Tang Yuhang's words. However, if he was told that the cost of this thing was actually less than one million, it was estimated that Tang Yuhang would have to be pulled over and beaten up immediately.

"Grandma Gong, senior sister." Tang Yuhang turned his head to look at the two of them, "Regarding this thing, please help keep it secret for the time being, otherwise it will cause a storm again." ”

Grandma Gong and Liang Yuting nodded in agreement, both of them know the importance of this thing to the scientific community, it can be said that many important experiments now, if you have this thing, you can directly deduce the process, at least more than half of the trouble now.

Without worrying too much about the holographic projection, a few people observed the data and immediately started working again. However, his heart is no longer calm, and he has complete confidence in what Tang Yuhang wants to do.

After all, holographic projectors have been made, maybe this thing can really be made? Everyone's confidence has increased and they are fully focused on their work.

At noon, several people ate the fast food sent by Wang Qianyu, probably rested, and immediately continued to work.

The technology is basically ready-made, and there is no need to do other superfluous experiments, plus Tang Jianjun and Grandma Gong are also experienced scientists, which also minimizes unnecessary mistakes that may occur in the production project.

Three days later, a cat leg that was almost about to be formed had been gradually completed, and Tang Yuhang took the induction area made by Tang Jianjun and handed it to the company's production department, asking them to use this as a template to make a thousand within a week.

This miniature sensor has been tested by Tang Yuhang, and there are no problems at all, and sure enough, his grandfather also has two brushes, at least this experience is not covered. Tang Yuhang silently praised his grandfather in his heart.

Although this kind of miniature sensor is really small, it is not difficult for the production department to make a thousand in a week by adjusting the size of a machine and turning on the assembly line.

Subsequently, after explaining a few words to the personnel of the production department, I drove back to the company. The company's workshop is not in the company's headquarters, but in a large rented factory in the suburbs.

After returning to the company, Tang Yuhang flipped through the phone book and found the phone number of his high school classmate Sun Xiaojie, and after thinking about it, he still dialed it.

"Uh......" The voice on the other side of the phone revealed a tone of disbelief, "Tang Yuhang? ”

"What's wrong?" Tang Yuhang smiled, "This tone, don't you remember me?" ”

"I'll go! It's really you! Sun Xiaojie still felt a little incredible, "Aren't you all running a company now?" I even bought a piece of your hoverboard. ”

"It's not ......," Tang Yuhang said helplessly, "It's as if I didn't recognize my old classmates after I opened a company......"

"Come on!" Sun Xiaojie also let go, "We two high school classmates for three years, I don't know you yet?" Let's just say it, what's the matter? ”

"Okay...... Tang Yuhang smiled, "I remember your sister is a veterinarian, right?" Can you introduce me to him? I have an experiment here that I need help with......"

Tang Yuhang didn't say what specific experiments were, but only introduced that he needed the help of a skilled veterinarian, and he would definitely not let his sister suffer.

"That's it......" Sun Xiaojie thought for a while, "Then let's do it, I'll call my sister out for dinner in the evening, you come over and talk to him personally, I don't understand the specific terms." ”

"Okay, that's for you." Tang Yuhang said, "We met in the evening, and we haven't seen each other for a long time, let's talk about it together." ”

"Okay, I'll book a place to text you later."

After a few more polite words, Tang Yuhang hung up the phone. He turned around and walked into the laboratory again, observing the progress of the experiment.

Besides, Sun Xiaojie was here, after hanging up Tang Yuhang's phone, he looked at it for a while and happened to have no class, so he took a taxi to the animal hospital where his sister was.

Sun Xiaojie's sister Sun Xiaofei also has one of the best skills in the veterinary community in Yushan, and is the chief physician of the largest animal hospital in Yushan. It's true that the technology is not said, but the fee is also very expensive.

Basically, the pets raised by people with good family conditions in Yushan are sick, and many of them are treated by Sun Xiaofei.

The taxi stopped at the door of the "Love Animal Hospital", and Sun Xiaojie got out of the car and walked into the hospital. I walked into my sister's office with a familiar car, and pushed the door and walked in without knocking.

There was a woman in a white lab coat sitting in front of the desk, and all she could see was a bright red shirt with a short black skirt, sexy black stockings and black red heels that were indescribably sexy.

A long curly hair with a fluffy braid tied at the back of his head, a handful of oblique bangs on his forehead that is tilted to the left, curved willow eyebrows, narrow eyes, long eyelashes, a high nose bridge, and a lip with a big red lipstick underneath are not inferior to celebrities.

"Xiaojie, why are you here?" Sun Xiaofei looked up at her younger brother and asked casually, "Is my girlfriend's pet sick?" ”

"Uh......" Sun Xiaojie was a little helpless, "Sister, I'm still single......"

"What?" Sun Xiaofei raised her head, "How long has it been since the last one broke up, and you haven't found a new one?" Then who do you fancy hurry up, there are so many beautiful women in your school......"

"It's not...... Sister," Sun Xiaojie interrupted Sun Xiaofei, "I have something to do with you today." ”

"What can you do?" Sun Xiaofei leaned back in her chair, "You are a freshman now, and the duty of a student is to fall in love......"

"Stop!" Sun Xiaojie said in his heart, so I didn't want to come here...... "I want to invite you to dinner tonight and introduce someone to you to meet ......"

"Yo!" Sun Xiaofei smiled, "I've started to introduce boyfriends to your sister, you can ...... now"

"What......" Sun Xiaojie interrupted, "It's a high school classmate of mine, and I started my own company some time ago, and you know Tang Yuhang!" ”

"Tang Yuhang?" Sun Xiaofei was stunned, "The one who invented the hoverboard?" ”

"Yes!" Sun Xiaojie said, "He called me today, and he has a very important experiment that he wants you to help with operating on a cat, so he wants me to introduce you to ......."

"That's ......" Sun Xiaofei thought for a while, "Okay, since it's your old classmate, I'll do you a favor." ”

After getting things done, Sun Xiaojie immediately got out of the hospital, didn't want to stay here at all, and after sending a text message to Tang Yuhang, he took a taxi back to school.

In the evening, Tang Yuhang drove to the hotel booked by Sun Xiaojie alone, and when he walked into the box, although he found the sexy royal sister sitting next to him at a glance, he still walked in front of Sun Xiaojie first and ignored Sun Xiaojie's greetings, and directly came to a big hug!
