Three months later.

Ten o'clock in the morning.

Today is the day of the first test after paraspinal nerve graft surgery for firefighters who were previously paralyzed.

Although it was only a paraspinal nerve transplant, the operation two weeks ago not only performed paraspinal nerve transplantation, but also replaced some of the patient's atrophied tendon tissue with nanomaterials as scaffolds.

It can be said that this is a direction that Zhao Sheng wants to carry out in the future.

That's what he loves the most, and what he wants to do the most, which appears in cyber-style literature and film and television works, the human body is connected to cyber components.

This is not an ordinary biological tissue implantation and replacement, nor is it a simple bionic or mechanical prosthesis, and it combines biology, machinery and electronics, which can really replace damaged or diseased human organs, without affecting the original function of the human body, and even after replacement, the function of the organ will far exceed the original degree of the human organ.

No, the firefighter guy, who had been bedridden for ten years, was now able to stand up after nerve grafting and nanoscaffold replacement of tendon tissue, and not only regained his normal mobility.

Looking at the paralyzed firefighter guy walking on the treadmill, Zhu Yong, who was standing aside, felt a little unbelievable, because three months ago, when this guy came to the high-end medical department, he was still paralyzed in bed, and now he is not only able to recover his normal mobility, but also looks like this, compared to when he was not injured and paralyzed, it seems to be stronger.

"Director Zhao, Professor Jin, am I dazzled now?"

Even though he has seen a lot of the world, the scene in front of him still greatly shocked Zhu Yong.

You must know that the firefighter guy in front of him, ten years ago, because he was saving people in the fire, he was smashed by a heavy object and broke his spine, resulting in complete damage to the paraspinal nerves, and in modern medicine, he has basically been judged to be paralyzed for life.

But now, the guy is not just on his feet, but he is also more agile and powerful than he was before he was injured.

"The effect is okay, and we have to look at the next nerve response test to know whether the nerve strengthening technology that my senior and I expected has worked."

Zhao Sheng nodded and said very indifferently.

Normal people's reaction speed is about 300 milliseconds, and it will decrease after the age of 30, and athletes can shorten their reaction speed to 150-180 milliseconds to specific stimuli (starting pistols) after specific exercises, and the limit of human reaction speed is currently recognized by the scientific community as 100 milliseconds.

The new nerves cultivated by stem cell technology have replaced the damaged nerves in the guy's body, which is equivalent to the renewal of the computer system, and there is also the replacement of tendon tissue under the nano scaffold, in short, the guy is equivalent to updating a new set of motor core system.

Now, it's time to test what kind of level the core system can achieve.

Soon, the firefighter guy, no, ten years ago, was a guy when he was injured, and ten years later, it should be the firefighter uncle Yu Feng, who reluctantly got off the treadmill and said to Zhao Sheng very excitedly: "Doctor Zhao, this feeling of running wantonly is simply great, in the past ten years, I have thought about death many times, Doctor Zhao, you gave me rebirth!" ”

"Hmm."

"How do you feel now?"

Zhao Sheng nodded and asked for Feng.

To be honest, although he is already very sure, he still has to be tested by facts.

"I feel like I'm faster."

Yu Feng felt his current situation, and he felt as if he could do something that he couldn't do before.

Zhao Sheng nodded, and the gel pen he was holding in his left hand fell out of his hand inadvertently.

Zhao Sheng didn't remind Yu Feng, but the gel pen fell and was still within Yu Feng's field of vision.

At the moment when the gel pen fell from Zhao Sheng's hand, Yu Feng instantly captured the trajectory of the gel pen, and then caught it lightning at the moment when the gel pen just began to fall from Zhao Sheng's hand.

Hiss~

Seeing this scene, Zhu Yong couldn't help but gasp.

Because although Zhao Sheng and Yu Feng were face to face, before the gel pen fell, they were also in Yu Feng's field of vision, but Zhao Sheng did not remind Yu Feng that Yu Feng just reacted subconsciously, and almost caught the falling gel pen in an instant, and this reaction speed has far exceeded that of normal humans.

"Yes, you're getting faster."

Zhao Sheng nodded and said to Feng.

"This..."

"Doctor Zhao, that's a good thing, there won't be any problems, right?"

Yu Feng was surprised and delighted by his own changes, and he was also a little apprehensive.

It can't be some genetic mutation, right?

Yu Feng couldn't help but think in his heart.

"What's the problem, it's just that your reaction speed is now a little faster than normal."

Zhao Sheng smiled and said.

"Let's take a test and see how fast your reaction speed is."

After a pause, Zhao Sheng led Feng to the side of the workbench again, asked Yu Feng to sit down, and prepared to start the professional reaction speed test.

"Of course, before you take the test, let's also test it and make an experimental control group with you."

Zhao Sheng said again.

"Then I'll come first!"

Hearing Zhao Sheng's words, Zhu Yong immediately volunteered.

Then, he sat down in front of the computer, opened the software, and started testing.

After ten minutes of unrelenting testing, Zhu Yong could only accept the fact that he was an ordinary person, because his ultimate reaction speed was 230 milliseconds.

This reaction speed can only be said to be decent.

"Minister Zhu, your ultimate reaction speed is already very fast in a normal person, and the reaction speed of an average person is about 300 milliseconds. Your reaction speed is close to that of some professional athletes. ”

Zhao Sheng saw that Zhu Yong was a little depressed, and couldn't help but smile and said.

"Generally speaking, professional athletes have a reaction time of less than 200 milliseconds."

After a pause, Zhao Sheng said again.

"Come on."

Zhao Sheng said to Feng.

With Zhu Yong as the control group, and the reaction speed of normal people is relatively fast, Zhao Sheng is also looking forward to it now, wanting to know what Yu Feng's current limit reaction speed is.

"Good!"

Yu Feng nodded and said expectantly.

Then, Yu Feng sat down in front of the computer and prepared to start the test.

Fifteen minutes later, Zhu Yong looked at the ultimate reaction speed displayed on the computer screen, and opened his mouth wide, looking dumbfounded.

Because the limit reaction speed displayed on the computer is 110 milliseconds!!

You must know that Zhu Yong's reaction speed was measured to be 230 milliseconds just now, which is relatively fast in normal people.

Now Yu Feng's ultimate reaction speed is 110 milliseconds, that is to say, Yu Feng's reaction speed is more than twice as fast as his!

What kind of concept is this, if the two of them fight, Yu Feng can beat him without injury, even if he is armed with a weapon or even a firearm, in a face-to-face situation, the reaction speed is as much as doubled, Yu Feng can predict and dodge all his movements.

As a child who grew up in the compound, Zhu Yong has been a military fan since he was a child, so he knows very well that such a person whose reaction speed has almost reached the limit, with a little training, is a god of war who makes the enemy fearful!
