I don't have a system but I have a hammer

10 minutes later...

"Sorry, this office is a bit small, you sit first, by the way, tea or coffee?"

Compared with the crowded hall downstairs, this office of less than [-] square meters is obviously more comfortable for me...

But the man in front of me with yellow skin and black hair, and the Chinese national flag on the table made me frown...

"Are you... from Huaxia?"

That's right, my entire face is covered with a turban, and the eye sockets are covered with sunglasses, so I'm not worried that the other party will find out my identity...

But the person in charge of a charity organization established by a beautiful country is actually a Chinese, which makes me feel a little uneasy...

"Ha...you misunderstood, I am a Chinese from a beautiful country..."

Maybe he knew it was weird, so the Chinese man pointed to the national flag on the table and added with a smile...

"Although I was born in the beautiful country, I lived in Beijing with my father for a long time when I was a child, so I have some personal complexes..."

"By the way, I have been to Tiananmen Square in Beijing... and I can speak Chinese... haha... let's not talk about this... Come, try the old tree black tea that is only found in Laos..."

Well, I'd love to try it, but I can't take off my hood so I can only watch...

"By the way, you are here this time to..."

Hearing the other party get straight to the point, I withdrew my gaze and pointed to my left leg...

"I want to personally donate 20 knives, but the condition is that you can help me find a suitable second-hand mechanical leg..."

The Chinese man was obviously startled when he heard the amount. It seemed that he hadn’t received such a large donation for a long time, and even his breathing became short of breath. Afterwards, he quickly suppressed the excitement on his face and opened his mouth to express his thanks …

"Also, I need this mechanical leg before tonight, I'm in a hurry, but I believe you can find it, right?"

After saying this, the smile on the Chinese man's face suddenly froze, but he could tell that I was not joking, so he only thought about it for a while, then nodded as if he had made up his mind...

"Sir, your request is not too much. If the donation is in place now, I think I can..."

Before he finished speaking, I took out the communicator...

"Give me the account number..."

The Chinese man was obviously a little surprised by my non-sloppy style, but he quickly reacted and reported his number overjoyed...

And when he confirmed that the 20 knives had already been deposited in the account, his whole face suddenly turned into a chrysanthemum with a smile...

"Haha, sir, you are really quick to talk, by the way, I don't know what to call you..."

I pretended to be indifferent and raised my hand...

"The title doesn't matter, what matters is when will I get that leg..."

The Chinese man nodded quickly, it should be...

"What you said is, don't worry, I have many patients with mechanical legs, and I will contact them now..."

Squinting my eyes, I asked a question...

"By the way, don't you need to see my injury? Or take the measurement of my leg?"

The Chinese man shook his head with a smile, his eyes flickered as if he had touched his own professional field...

"Haha, you may not know much about prosthetics. Let me explain to you. The socket, oh, is the place where the joints of the human body are stored. There is no fixed size for this, because it can be adjusted at any time. What those mouths say can help you measure it. The size of the legs needs to be customized, and they are generally liars..."

"However, there are two types of prosthetics, externally powered prostheses and mechanically powered prostheses. If it is the latter, although there is no need to measure the size, there are microprocessors and memory sensors at the joints, which will record your gait habits, so as to be more accurate. Good to help you get back to your normal way of walking, the downside is that this process takes a long time..."

One thing he said was very professional, but when he mentioned it, I suddenly thought of my prosthetic limb, so I asked without confidence...

"By the way, have you ever heard of a prosthetic with neural sensing?"

The Chinese man who was looking through the patient's information suddenly became weird after hearing what I said...

After thinking for a moment, Wei Wei gave the answer...

"If there is one, it does exist, but so far there have been no successful cases. To be precise, its full name should be...uh...Targeted Muscle Nerve Transplantation! Abbreviated (tmr)!"

Before I had time to explain, the front desk lady appeared at the door of the office...

The Chinese man solemnly handed her the patient's information, and at the same time asked...

"Call everyone to help find it, see if there is any patient who is willing to sell the mechanical leg, and the reward is... [-] knives!"

Watching her go, he turned to look at me...

"I'm sorry, although the number of patients with mechanical legs is very large, you also know the current situation, and we can't guarantee how many people are still alive, but don't worry, as long as there are living patients, I believe no one can Refuse the temptation of [-] knives..."

Of course I understand what he means, not to mention a mechanical leg, as long as the price is right, I am afraid someone will be willing to sell a real leg...

"Sir, you don't need to worry, there should be good news soon, by the way, try this tea..."

I rejected his kindness, and based on the principle of looking for something to talk about, I returned to the question just now...

"By the way, the operation you just mentioned..."

It seems that I didn’t expect me to be so interested in the knowledge of prosthetics. The Chinese man seemed a little surprised, but immediately smiled and continued to popularize science for me...

"Oh, you said TMR surgery, ha, in fact, this has already involved physiology. You should know that the human brain first sends bioelectric commands through the spinal cord, and then the peripheral nerves control the muscles of the limbs..."

"So when a person is amputated, the information transmission pathway still exists, and the peripheral nerves still carry the bioelectrical signals generated by the brain, but the executive unit is missing because of the amputation..."

"What the tmr operation needs to do is to direct the nerves that have lost their executive units to healthy muscle parts. For example, transfer part of your amputated leg muscle nerves to your chest muscles..."

"At this time, if you want to move your legs, you can feel the electrical activity in your chest, so you can use your brain to control the chest muscles first, and then use the chest muscles to control the prosthesis..."

Hearing this, I frowned slightly...

"Then why can't it be directly controlled by the brain? Or controlled by other more flexible parts?"

The Chinese man smiled...

"The difficulty of the former is that the nerve signals directly transmitted by the brain are very weak, and there is no way for the prosthesis to intercept them. The difficulty of the latter...haha...is not difficult, that is, if you use your fingers to control the movement of the prosthesis, can you imagine? Shaking hands with others The prosthetic leg kicked someone else while you were there?"

Speaking of which, we both laughed at the same time...

However, before we could continue laughing, a siren suddenly sounded outside the window...

Drop drop…

Oh shit!
