Gu Cheng immediately smiled politely and handed a business card to the other party, saying, "Hello sir, we are from Tianqing Technology Company, a technology company focusing on medical rehabilitation. I am Gu Cheng, the founder of the company. This time he came to disturb him for your wife. We hope to help her return to the normal life of a person."

At the beginning of the company, it is no big deal for the boss to come out to do business.

Tianqing Technology?

The man was suspicious with his business card. He had never heard of such a company. However, after hearing Gu Cheng's words, he was stunned for a while and became even more confused: "Are you selling? Sorry, we don't need it..."

As the man was about to close the door, Gu Cheng was sweating profusely, lifted his legs forward and stuck the door, and hurriedly said: "Sir, you are wrong. We are here to seek volunteers. Our R&D department has developed an advanced high-tech bionic prosthetic limb, which is about to enter the market stage. Before that, we are collecting actual data to make further improvements. If you agree, we will provide your wife with a free prosthetic limb."

Gu Cheng understands that it is not easy to sell business in the door these days, but he also understands the other party, and sales are indeed very annoying.

"free?"

The man hesitated for a moment and was moved when he heard the word "free", but he still had some reservations in his heart and couldn't help but say: "Give things free, and then ask for some messy service fees. I've seen a lot of these routines."

Gu Cheng said helplessly: "Brother, we are technical engineers, not salesmen. The purpose of this visit is to collect data from actual users and then take them back to analyze them, that's all."

The man was half-believing and half-doubted when he heard this, but he also moved and opened the door: "Sorry, please come in and speak."

"We should say sorry for the uninvited guest."

After politely speaking, after entering the house, the house is not big, less than a hundred square meters.

It was lunch time. Gu Cheng looked around and saw a young woman sitting on the dining table. She had a single ponytail on her head, had her right hand amputated, and her elbow joints were all gone.

She was trying to pick up food with her left hand. She was not left-handed. She had difficulty even eating without her right hand. Although she had been studying for a month, she was still very uncomfortable.

She also stopped when she saw Gu Cheng and others coming to the house. The man brought a few stools: "Please sit down!"

"Thanks!"

Gu Cheng and others sat down, and the man turned his head and looked at the dining table: "Shanshan, come here!"

The woman is quite beautiful and is considered a beauty. After a brief introduction by the man, they had just gotten married less than a year and a half. A terrible car accident four months ago made her right hand crushed by a truck tire and finally had to amputate her limbs. The reason why she was shocked was that she almost had to be in her head.

After listening to the man's story, Gu Cheng nodded silently and then said, "Mr. Zhang, we won't say anything polite. Madam, can you let me see your hands? You have to look at both hands."

Hearing this, the woman hesitated for a moment and finally reached out her disabled right hand and normal left hand. Gu Cheng looked at it and then turned his head to the employee next to him and said, "Take it out the youngest one."

"OK."

The employee immediately placed a large box that he had lifted up in front of everyone. Under the notes of the male and female owners of the house, as soon as the box was opened, he saw three arms of different sizes placed inside.

Both of them looked surprised because this imitation prosthetic limb looked really real. If it was thrown on the road and was touched with some ketchup or something on it, it would be scary.

"this……"

Gu Cheng smiled and said: "The surface layer is a bionic muscle skin mainly made of silicone material, and the inside is a precise mechanical structure, right..."

As he said that, he picked up the smallest one, then turned the angle to show the grafted end to both of them, and indeed saw some metal structures.

The man hesitated and said, "This thing is really OK?"

Gu Cheng said confidently: "If you can, you will know if you can. What I want to say is that you must be OK, and you can guarantee that this beauty can waving her arms."

"Then give it a try first."

The woman finally spoke, a little urgent. Gu Cheng understood her. Not only was the amputee affected in life, but this was not the biggest obstacle. Psychological pressure was the biggest obstacle.

Gu Cheng and others no longer hesitated, and immediately came to the woman. The smallest mechanical prosthesis just fitted with her hand shape. First, they put on a nerve sensing cover, and then grafted the prosthesis to her elbow. The grafting end of the prosthesis stretched out several thin plates to fit on the arm. After the two flesh-colored bionic ligaments were mounted on the shoulders, just like a suspender.

Only by doing all this can you ensure that the prosthetic limbs will not fall off when your hands are put down and lift things naturally.

The woman couldn't help but raise her right hand lightly, but the prosthetic limb below her elbow still did not react at all. However, when she put on the prosthetic hand, she felt inexplicably like a normal person. At least she had a symmetrical beauty, and had a wonderful psychological change.

"Is it just such a decoration? Can it not move? Can I control it?" the woman asked impatiently.

"Of course not, of course you can move, of course you can control it." Gu Cheng said with a smile.

"What should I do?" the woman asked quickly.

"Just control it with your mind, just like your left hand. What you want it to do is up to your brain." Gu Chengru replied.

When the woman heard that she tried to make the five fingers on the prosthetic limb move according to her own thoughts, she did not react at all. Seeing her looking at her with confusion, Gu Cheng said with a smile: "It's not powered yet..."

The employee immediately handed him a battery board, and Gu Cheng smiled and said, "Extend my right hand and come over, Mr. Zhang, you can also come over. Through the back of the little hand, use your finger to touch the surface bionic skin, find a button that looks the size of a pea, and then apply a pressure to press it. This way, the bionic skin can be opened and the metal structure inside can be seen."

Both the couple watched and listened seriously. After Gu Cheng finished speaking, he did the truth. Sure enough, the surface skin 5 cm behind his wrist was protruding.

After opening it, Gu Cheng looked at the two of them: "This empty slot is the energy slot, which is also the place to put the battery board. This battery is 19,000 mAh, which can ensure the battery life of the prosthesis for about 5.5 hours. The time is not long. Our company will definitely improve the battery technology in the future. However, the battery board is not big and easy to carry. It can be kept in a bag or in a pocket. It is also very easy to change the battery. Just change the battery as if it was a mobile phone in the past. It is very simple and has waterproof function."

In the future, we will definitely develop batteries, but at the beginning of Tianqing Technology, the hardware is basically purchased from major manufacturers, and it will be different after completing the first pot of gold at the beginning.

Gu Cheng immediately demonstrated to them how to unload the battery, which was indeed very simple.
Chapter completed!
