I may not be human [holographic]

In the next week, the state of often familiar with the injured leg remained at the same level, and it seemed that there was no progress.

After all, he didn't come here to treat diseases, but to provide experimental bodies for the research and development of new prosthetic limbs.

The direction of experimentation changes from time to time, and even if some inspiration is caught, it will take a lot of repeated experiments on this inspiration to finally determine whether this direction is reliable.

Therefore, Chang Fan can only be tortured by the same process day after day, and it is completely unpredictable when this kind of day will end.

Sure enough, as Mr. Zhou said, after the afternoon of the first day here, Chang Fan no longer had the energy to have such a beautiful exchange with Lin Zhengyan.

Even the matter that he swore to take care of Lin Zhengyan, it turned out that Lin Zhengyan took care of him instead.

Lin Zhengyan's rehabilitation during this period has been very effective. He has completely abandoned the auxiliary vehicle, can walk around by himself, and can even do some light-intensity exercises.The work of going to the cafeteria to get food every day was also taken over by him from the experimenters and nurses as extra exercise.

After another half month, Lin Zhengyan's basic daily activities gradually recovered, and he began to increase the amount of exercise under the plan of the experimenter, hoping to achieve a healthier state.

And Chang Fan also ushered in an important challenge for him one morning.

"This sensing device is the latest version we made based on the experimental results accumulated before."

Mr. Zhou held a cup, gestured under the familiar wound, and explained: "The sensor is controlled by electrical signals, and the instructions of the electrical signals are issued by the neurons in your legs. What we need to do now is to put The nerve cells you have activated are connected to the sensors and then used to connect to the mechanical prosthesis. However, until the operation is over, I will not be sure whether it will cause pain or not."

Chang Fan wiped off his sweat and said with a smile, "It's okay, just come."

Connecting the nerves to the sensors required an extremely delicate operation that began that morning and continued until just after one o'clock in the afternoon.

When Chang Familiar was pushed out of the operating room, the effects of the local anesthesia had not yet passed, and he fell into a deep sleep—during this period, he was affected by the activation of the nerves in his legs, and the wound was always painful, sometimes weak , sometimes stronger, and in order to keep the nerves in the best state of the experiment, analgesia cannot be used frequently, so I basically can't sleep well at night.

Seeing Chang Wen's sleeping peacefully, Lin Zhengyan stroked his forehead hair distressedly.

"Actually, your rehabilitation has basically been completed, and all the indicators of your physical examination have returned to health."

Elder Zhou said softly at the side: "As Young Master Chang, there is no need to make this kind of experimental subject, but when I asked him two days ago if he wanted to stop the experiment, he said that since it has started, it must be completed. If it is You come to persuade, it may be effective."

Lin Zhengyan was silent for a moment, and said, "I can understand his thoughts, so even if I see him in such pain, I don't want to persuade him to give up halfway."

Mr. Zhou sighed, and said, "Scientific research is not like other things. If we persevere, there will always be an end. This is an exploration in a new field. Before the results come out, we don't even know whether we are going in the right direction. .”

Lin Zhengyan laughed, "If you were really unsure, you wouldn't have let him undergo sensor surgery so quickly, would you?"

Elder Zhou smiled, and didn't say anything further, he just said: "He may wake up in pain when the anesthetic wears off, please take care, ring the bell to call me if you have any problems."

Lin Zhengyan nodded and sent Mr. Zhou out of the room.

When he returned to the bedroom, he didn't dare to make too much noise. After adjusting the window shades to a fully closed sleep mode, he sat back on his hospital bed and read an e-book.

After three or four hours, there was some movement from Chang Fan.

Lin Zhengyan immediately put down the book and went to check it, but he saw that Chang Fan had opened his eyes, his brows were slightly frowned, but he didn't seem to be in pain.

"Are you awake?" Lin Zhengyan brought him a glass of light salt water and asked, "Does your leg hurt?"

Chang Fan got up, took the water glass and drank it up, then looked at the injured leg suspiciously, and said, "It doesn't hurt if you don't move, but it still hurts a little when you exert force. Where's Zhou Pei?"

"I'll call him right now." Lin Zhengyan said, raising his hand to ring the bell.

But Chang Fan grabbed his wrist.

Chang Fan smiled and said: "Don't worry, I finally feel less pain here... Come, give me a hug."

As he spoke, he opened his hands and smiled at Lin Zhengyan.

It's true that the two haven't had a good conversation for a long time. Before Chang Fan always looked pale and sweaty, and couldn't sleep well at night, Lin Zhengyan couldn't bear to let him force himself to chat with him.

Lin Zhengyan sat down beside the hospital bed, put his arms around Chang Fan's waist, rested his chin on his shoulder, and said, "I feel that Mr. Zhou's experiment is about to succeed."

Chang Fan chuckled and said, "If he didn't see the hope of breaking through the bottleneck, he wouldn't let me be the first person to install a new type of prosthetic. If everything goes well, I will become a successful case. This laboratory It is possible to be linked to the Ninth Research Institute more smoothly. The appeal of the Chang family is placed there, and the use of human bodies for experiments will not be criticized for too long."

Lin Zhengyan said: "I guess it's the same. If you are still far from success, he should arrange some dispensable experiments for you. When I recover, he will drive us both out."

Chang Fan stroked Lin Zhengyan's back and said, "It is estimated that there should be results within a month. The Federation will have a cutting-edge technology summit in early May, and he will definitely present results before the summit."

After finishing speaking, he raised his hand to pinch Lin Zhengyan's chin, making him look at him, and said, "There are more important things than this."

"What?" Lin Zhengyan asked.

Chang Fan didn't speak, and kissed Lin Zhengyan's lips directly.

After a long time, the two gradually separated, both blushing and emotional.

Chang Fan said in a low voice: "Recently, I have worked hard for you."

Lin Zhengyan shook his head and said, "You are the hardest one. Originally, you didn't have to live here with me."

Chang Yan smiled and said: "Yes, originally I could stay at home, eat and drink, play games, and my legs don't hurt..."

Lin Zhengyan didn't say a word, waiting for the second half of the sentence that often knows this kind of ridicule.

Sure enough, Chang Fan quickly added: "...But who told me that I don't have you at home?"

The two lay on the bed for a while, until Lin Zhengyan felt that the direction of Chang's palm was becoming dangerous, so he hurriedly got up and rang the calling bell beside the bed.

"You bastard..." Chang Fan laughed angrily, "...you won't give any welfare you want."

Lin Zhengyan blushed, and said solemnly with no expression on his face: "Finish what needs to be done first, and we will have more time in the future."

Mr. Zhou and the experimenter rushed over quickly, brought Chang Fan back to the experiment room, took out the instrument to test the sensitivity of the sensor, and asked Chang Fan about his personal feelings when trying to control it with nerves.

As Zhou Lao adjusted the instrument in his hand, Chang Fan suddenly shouted and cursed, startling Lin Zhengyan who hadn't left the door yet.

The experimenter was not surprised, and said calmly: "The pain level just now reached SS, Mr. Zhou."

Mr. Zhou was also very calm about Chang Fan's behavior of swearing and swearing, and adjusted the instrument in his hand again, asking: "What about now?"

Chang Fan raised his hand and wiped the cold sweat that had been provoked all over his face just now, and said, "It's okay now, it's sore, it doesn't hurt."

From the corner of his eye, he saw Lin Zhengyan still standing outside the open door, and he turned to the experimenter and said, "Close the door."

He never let Lin Zhengyan watch his experiment process before, because he didn't know how high the pain level would be.And he's not the kind of person who can only grit his teeth and bear it. When he's in pain, he swears bad words one after another and becomes irritable. He also blushes and has a thick neck, and sometimes he's forced to cry rationally... It's so ugly, I don't want Lin Zhengyan to see it. .

Of course, more importantly, he didn't want to see Lin Zhengyan look sad because of him.

Lin Zhengyan knows this, so he never willfully insists on watching.That's why he was taken aback when he heard this earth-shattering swear word today.

The experimenter came to close the door, Lin Zhengyan obediently stepped aside, and leaned against the wall outside the door to wait for the results of this experiment.

The soundproofing of the experimental room was very good. He stood against the wall and could not hear any sound inside.But just judging from the sentence that Chang Fan inadvertently yelled just now, and the calm expressions of Mr. Zhou and the experimenter, every experiment before, Chang Fan's experience is probably similar to this one.

After waiting like this for more than two hours, Chang Fan was helped out of the room by the experimenter.

A new type of prosthetic was attached to his leg. It was no longer a rigid mechanical structure, but a prosthesis wrapped in carbon fiber material that looked more like a human body.And, miraculously, when the leg is in the air, it can also make some simple movements autonomously.

"Success?"

Lin Zhengyan looked at that leg, with unconcealable surprise in his eyes.

"It still needs to be improved." Mr. Zhou replied: "The part of autonomous control has been solved, but the tactile feedback is still a little insensitive."

"The feedback is basically inaccurate, as if he had been given anesthesia." Chang Fan rarely smiled after the experiment.

Mr. Zhou was also very helpless: "But if the level of electrical stimulation is increased, it will cause pain again, which is not as expected."

Chang Fan curled up his legs, feeling the new limbs, and said: "The first version has been made like this, and I can feel it now. It's not the prosthetic limbs I couldn't control before, but more like my own. Legs, just a little numb."

Mr. Zhou said: "The level of the lower limbs is fine, but the upper limbs, especially the fingers, require higher sensitivity. This experiment still needs to be continued in order to solve the problems of more disabled patients."

Hearing this, Chang Fan raised his eyebrows and said, "Don't worry, as long as you submit this achievement at the summit, the Chang family will be able to keep this laboratory and name it under the Ninth Research Institute, and there is no People can steal your grades. After you submit your results, you may even get sponsorships. The market for prosthetics is not small, and someone will always be willing to end up.”

Elder Zhou finally relaxed a little, and said, "Personally, I don't care, I just hope that we won't be forced to suspend the experiment in the future, so that we can achieve the results we really want."

Chang San smiled and said, "Don't worry."

The experimenter walked around the room twice with Chang Fan, and said, "Mr. Zhou, he seems to be adapting well. Can the stress test be done now?"

Elder Zhou glanced at the monitoring data and asked Chang Fan, "How long can you go now?"

Chang Fan put his arms around Lin Zhengyan's shoulders, pulled him into his arms, and said, "If I have him to accompany me for a walk, it shouldn't be a problem if I walk a dozen or so kilometers."
