I can extract side effects

"Dad, Mom, come and see my new mechanical bionic hand!"

As soon as Tang Jian entered the house, he shouted excitedly.

The parents knew about this a long time ago and were waiting anxiously. When they heard the sound, they immediately ran over.

"Are you back? Come, show us."

Tang Jian skillfully demonstrated a series of operations such as making calls, playing with mobile phones, twisting bottle caps, drinking water, taking out keys to open doors, etc., all of which are actions to be done in daily life scenes.

Seeing the flowing movements of the bionic hand, the parents burst into tears.

"My God, your fake hand is no different from your real one." The old mother carefully touched his bionic hand, showing a happy smile.

Father looked at all this and smiled happily, but he still habitually provoked his thorns when he watched.

"Okay, that's the hand. It doesn't look real. They should install a more realistic hand for you so that you can't see it."

Tang Jian was not happy now: "I just like hands like this, they are super handsome, okay, many people on the road said they look good, and they all wanted to take pictures with me."

He raised the water bottle in his hand: "A little girl gave me a bottle of water."

The mother's eyes lit up immediately: "Girls like this kind of hands? That's okay."

After finishing speaking, he patted the old man and persuaded: "Listen to the young man, this style is very fashionable, and the little girl likes it. Don't care if it is true or not, as long as it doesn't delay my son's search for a partner."

The old father was a little helpless: "That's fine, if it can help you find a partner, this style is not bad."

Tang Jian was speechless for a moment: "I'm not talking about liking. What are you thinking? My only thought now is to find a job sooner."

The old father nodded, expressing his approval: "Since you can do something, you have to find something to do. Your game competition is not a serious job, you still have to go to work."

"Well, I see. During this period of time, I will take the Sanqing test and look for a job at the same time."

Tang Jian agreed. He used to be disabled and couldn't do much work. Apart from delivering food, he couldn't find a suitable job, so he could only stay at home and play games.

After all, he is also a college student. Now that he has all the hands and feet, he naturally wants to find a job he likes and live a normal life.

After all, there is hope in life again, who would like to put it badly at home.

Just like what my parents said, find a class and talk to a girlfriend, and you will have hope in life.

In a peaceful and joyful atmosphere, Tang Jian returned to his room after dinner.

He noticed that as soon as he walked into the room, the bionic hand began to recharge automatically.

"This thing has its own wireless charger, advanced!" Looking at the wireless charger plugged in by the bed, he was surprised and delighted.

"Now I'm not afraid that the battery will run out after use. Although the speed is slow, it can be charged all the time, which is enough."

This bionic hand looks like metal, but it is actually relatively light. Only the arm is relatively heavy, and the palm and fingers are not heavy.

He guessed that only the skeleton is made of metal, and the other parts should be made of light plastic, and then the outer shell is sprayed with a layer of metal coating.

The joints are very flexible. When the fingers do small movements such as typing, they don't need to use too much force. They only need to move lightly, and there is a sense of smoothness.

The response is also very sensitive, and even the slightest tactile feedback can be adjusted in real time to make the movement easier.

In this way, unless it is some complex movements that require force, the energy consumption is relatively small and the battery will be more durable in daily use.

After experiencing it for so long, Tang Jian found that under the stimulation of electric pulses, the nerves at the end of his stump, which had already shrunk, had begun to adapt and slowly recovered.

When he ate, he held the rice bowl in his hand and felt the temperature of the rice through the wall of the bowl.

Although he knew that this was a mechanical hand that would not be injured, the heat from his fingertips still made him subconsciously feel hot.

"The freshly baked rice may indeed be a little hot, which is why there is such a strong feeling."

Holding the right hand with the left hand, the left hand did not feel the body temperature, but the right hand felt a burst of metallic coolness, and I suddenly understood a little bit.

"The sense of temperature is still not that keen. It seems that the nerves have not fully recovered, and I can only feel high and low temperatures for the time being."

"Fortunately, the nerves in my limbs were only damaged, and they can regenerate after healing. If the central nerves such as the brain and spinal cord are damaged, it will be difficult to recover."

Tang Jian thought to himself, and couldn't help but feel a little lucky.

Suddenly, after a few beeps, the phone rang.

After a closer look, it turned out that Zhu Jun @ him in the group.

"Xiaojian, how does it feel to test the bionic hand today?"

Tang Jian smiled slightly, turned on the camera, took a picture of the bionic hand typing rapidly on the keyboard, and sent it to the group.

This group is basically disabled people who love e-sports, some continue to play games, and some have changed careers to deliver food.

As soon as the small video was released, it caused a sensation in an instant.

"Wow, this bionic hand is amazing!"

"The fingers are so flexible, they don't look fake."

"If it was flesh-colored, I would definitely think it was real."

"Awesome, much better than those cosmetic prosthetics."

"How much is this thing? I really want to buy one."

"I heard people who sell prosthetics say that bionic hands are very expensive. Domestic prosthetics are all cosmetic and useless. Only foreign countries have that kind of smart bionic hand, but it costs at least 200,000. I can't afford it even if I sell it. ah."

As soon as these words came out, everyone fell silent for an instant.

After a while, Zhu Jun said: "Foreign bionic hands are indeed very expensive. The price of more than 100,000 to 200,000 yuan is normal, but I don't think Sanqing should be so expensive."

With this topic together, everyone immediately talked about it.

"I hope so. There are no other bionic hands in the main country. You can only buy Sanqing's. You have to buy it at any price."

"Think about the benefits. After you buy a bionic hand, you don't have to worry about finding a job. As long as it is made more realistic, ordinary people will not recognize it at all. If you wear thinner gloves, who will know that you are disabled?"

"Yeah, let's take a long-term view and think of it as a productivity tool."

"That's right, think about it. If you are disabled, you can't find a job and you can't make money, but with it, you can at least have a job. If you calculate it this way, you will pay back your capital in a few years."

"That's right, I just don't know if the bank is willing to give me a loan?"

"If you can give me a few years of installment loans like a house loan and a car loan, I will definitely buy it immediately."

"Think too much, this thing is still being tested, let's ask Xiaojian how it works."

"Yes, Xiaojian, tell me about your experience."

"See what's different from Xiaojun's. We can't use his, but you can look forward to it."

"Okay, I'll take a video for you to watch." Tang Jian smiled and immediately agreed.

He hurried out of the bedroom, opened the refrigerator and looked, only to find that there was only a plate of washed grapes in it, and brought the whole thing back.

Then he put the phone on the stand, turned on the camera, and pointed it at himself.

"Next, I will show you how to eat grapes with this hand."

Tang Jian waved his bionic hand at the camera, stretched out two fingers, and picked up a grape.

Then, hold the grape between the tips of your thumb and forefinger, and squeeze it gently and hard.

Light green pulp popped out.

This time Tang Jian raised his hands together and carefully tore off the purple-red grape skins on the outside.

Soon, a round fruit appeared at his fingertips.

He stuffed it into his mouth and ate it sweetly, and he couldn't help showing an intoxicated smile at the camera.

"It's so delicious. I haven't peeled grape skins in three years. I used to stuff them into my mouth and eat them, and just spit out the skins."

After the video was shot, it only took 1 minute, and he quickly posted it to the group.

"Look, this bionic hand is really easy to use. It's no different from my real hand. I won't lie to you."

The group of friends read it eagerly, and instantly became excited.

"My God, it's amazing to be able to peel grape skins."

"I don't think it's so clean if you have hands."

"Real people still have disabled hands, but this robot doesn't seem to have disabled hands at all."

"Such an easy-to-use bionic hand is worth the money!"

"That's right, you can't buy it anywhere else. I've seen videos of foreign bionic hands, and it's incomparable with Sanqing's."

"It's just that this robot arm looks a bit conspicuous. It would be better if it could be made into a flesh-colored color, which is more realistic."

"Actually, I think this one has a more technological sense. It looks very tall at first glance. It has a kind of, what, what kind of cyberpunk feeling. It's so handsome."

Tang Jian couldn't help but said: "Sanqing said that it will be made into metallic or flesh-colored ones according to the needs of users. Whether they want cool or realistic, they can satisfy it."

"Hey, but I like metallic colors, which have a sense of future technology."

He patted his thigh, and then added.

"By the way, I forgot to mention that this hand has a sense of touch. It can feel soft or hard things, and it can also feel the temperature. When I hold the rice bowl when I eat, it feels a little hot."

"Anyway, basically, it has the feeling that a real hand should have."

Hearing this news, everyone was even more shocked.

"Fuck, no way, this is too black technology."

"It's really awesome beyond my imagination, I really want to put it on and try it."

"At this moment, the prosthesis on my leg is no longer fragrant."

"Can you ask Sanqing for me, do they do leg prosthetics? I really want my prosthetic legs to feel tactile again."

"That's right, with such technology, a bionic leg should also be made. It must be simpler than a bionic hand."

"I don't ask too much, as long as I can feel my legs."

Now, like Tang Jian, several people who lost their legs or hands couldn't hold back.

After watching the video made by Tang Jian, they were so excited that they wanted to try it crazily.

"@小健, @诸俊, is there still a place for testing Sanqing's bionic hand?"

"Yes, they are all brothers, don't forget me if you have the chance."

"I really want to go, can I go for the test at my own expense?"

Zhu Jun thought for a while and said, "Let me ask for you, don't worry, they can't just test one person with this thing, and they will definitely recruit another person."

"Yes, I think so too." Tang Jian echoed.

He also sincerely hopes that these brothers can get the opportunity to test and experience the feeling of being reborn after a severed hand in advance.

After a while, Zhu Jun sent a link to the Longtu app.

"Brothers, good news. Sanqing will continue the recruitment test next week. Please pay attention and remember to sign up when the time comes."

Everyone immediately cheered, and the group was filled with a festive atmosphere.

"Great, when I get the bionic hand, I don't need to drive the eMule with one hand anymore."

"Hehe, I want to install a prosthesis that can run, so I can climb the seventh floor in one breath, and I don't have to worry about delivering food anymore."

"Hahaha, I'm different from you. I don't have two hands. If possible, I wish I could have four hands."

Seeing the laughter of his friends, Tang Jian felt a lot more relaxed.

He had a vague feeling that since the bionic hand was made, the bionic leg must not be far away.

Sure enough, the next morning, as soon as I arrived at the laboratory.

Wang Dali ran over mysteriously.

"Hey, I have a question, do you want to update this artificial leg?"

"What?" Tang Jian was stunned, and there was only one feeling in his heart, this happiness came too fast.

Wang Dali scratched his head and said with a simple smile.

"Looking at you wearing this prosthesis yesterday, your walking posture seems a little unnatural, so I thought, anyway, I have already made a bionic hand, so there is no reason not to make a bionic leg, right?"

"But if you don't want to, just pretend I didn't say it."

"I am willing!" Tang Jian almost jumped up, and immediately agreed, for fear that it would be too late and the other party would regret it.

"Alright then, I'll make a custom-made bionic leg for you."

Wang Dali took him to a testing room, asked him many leg questions, and took a video of Tang Jian walking.

The way he stands, the way he walks, how his legs exert strength, etc., are simply 360 degrees without dead ends, and all aspects are photographed.

Also re-measured height, leg length, leg circumference, etc.

During the measurement process, Wang Dali found that Tang Jian's legs were actually half a centimeter shorter, and the sockets did not fit very well.

"Uh, how much did you pay for this prosthesis? It doesn't feel particularly suitable for you."

Tang Jian smiled bitterly: "My prosthetic leg is about 20,000 yuan, and it's not cheap."

"There are more expensive ones, equipped with a smart chip, which is said to be able to run and jump, but it costs seven to eighty thousand. I'm not willing to install it, and I don't think it's necessary."

"Anyway, as long as you can walk, the one I bought is actually okay. Although walking always feels a bit awkward, at least this socket is quite comfortable. It won't be red and swollen after walking for a long time. I'm quite satisfied."

"As for it being shorter, I can't help it. After a long time, the leg muscles will definitely shrink a little. Besides, this socket was made by a master craftsman. He did it purely by hand, so it must not be as precise as a machine. "

Wang Dali grinned: "Understood, in fact, the technical content of the prosthetic leg is not high, it is a bit worse than the prosthetic hand, so what I am doing for you now is purely manual work, ha ha."

Tang Jian was stunned again: "Ah? This..."

"But don't worry, there is no problem with the accuracy." Wang Dali was talking, but his hands didn't stop for a moment.

After collecting the information, he made a cast of Tang Jian's leg in plaster.

"The model is ready. Soon, your legs will be ready in a few days."

"Ah, so fast!" Tang Jian didn't know what to say other than opening his mouth and exclaiming.

In this way, three days later, when I came to take the test again.

A brand new bionic leg was also placed in front of him.

"Come on, try it."
