Chapter 2 Chapter two

If the children's hearts were filled with awe and admiration just now, then after the kisses were sent, these feelings began to change, Dugu Hero became a little naughty boy who made people laugh and love.But in any case, I am absolutely convinced of Xing Xing's martial arts. I have seen it with my own eyes, and it is definitely not Jin Yong Gulong's fiction. Xiaogang's father called the children to come over, and Martin took a few strides ahead of him, and was the first to step onto the console.The following developments were quite unexpected: Ma Tian snatched Xiaogang's father in front of him, and knelt down with a plop: "Uncle Zhu, I was lucky enough to witness this performance today, and only then did I know that the martial arts written by Jin Yong and Gu Long are true. Please accept me as your apprentice."

This trick stunned the other three children, hesitating, wondering if they should follow his example.Professor Zhu's face darkened, and he said disgustedly: "What are you doing? Get up! I hate things like kneeling and kowtowing!" Ma Tian defended in confusion: "In martial arts novels, apprentices pay respects to teachers like this." "Get up, get up and talk!" Martin stood up slowly in fear, and Professor Zhu softened his tone and said: "Kneel down and kowtow, this is the most blush and disgusting legacy left by our ancestors. Fortunately, this era has passed , remember, never kneel down to anyone in the future, no matter to anyone!"

"But……" "No matter to anyone, even the master, the parents and the king - of course, there is no king for a long time. Let me tell you, although I love to read martial arts novels, I really can't bear some things in the book, like kneeling and kowtowing. , martyrdom, married women, a couple of women working together, and so on. These are the dross in Chinese culture, and they are by no means worthy of nostalgia or boast. Unfortunately, even masters like Jin Yong and Gu Long are sometimes exempt from vulgarity...well," he laughed He said, indicating that this page has been turned over, and jokingly said, "If you want to be an apprentice, why don't you find Dugu Hero, I have no martial arts."

"No!" Martin protested, "I know you are Dugu Xingxing's master, a hidden master of martial arts. Xiao Gang, don't you think so? Are you also kept in the dark?" He Sincerely persuaded Xiaogang, "Come on, let's beg Zhu Daxia to accept us as disciples together, your family's unique skills cannot be lost in your generation." Xiao Gang was confused.He often fights with his father, and has never noticed that his father has any unworldly martial arts.However, it is also possible that he is hiding deep in Ruogu, which is a common plot in martial arts novels.At least, Dugu Xingxing's martial arts was seen with his own eyes just now, so he couldn't be self-taught.He hesitated and said, "Dad..."

Feifei quickly poked Bai Yi: "What should we do? I wonder if Uncle Zhu will accept female disciples?" Bai Yi looked at Uncle Zhu, and said softly, "Uncle loves us the most. If he really has peerless martial arts, he will definitely pass them on to the four of us." Xiaogang's father turned to Professor Lin and said, "Mr. Lin, what should I do? I'm in trouble." Lin Jun grinned: "What should I do? You teach me." Martin saw that there was a door, and habitually wanted to kneel down again—but he stopped in time, and hurriedly asked: "Uncle, how should we apprentice? Salute or bow?"

Xiaogang's father smiled and shook his hands: "No need, no need. Come on, I'll tell you the truth." He made the four children sit down, pressed the button, and a transparent baffle rose around it to isolate the noise of the laboratory.Press it again and the bezel turns milky white and is no longer transparent.He said: "Listen to me patiently, this cannot be explained clearly in a few words." The children fell silent and looked at him eagerly.Zhu Yizhi smiled and said: "After I reveal the truth, I don't know whether you are disappointed or happy. Listen, this is not some peerless martial arts, it is science, not martial arts."

"Science?" the four said in unison. "Yes, science. Science is myth or magic that can be realized. I think you know enough about this. Just a few examples: If you send laser guns to the Ming Dynasty, will it be considered magic? If Sending a computer 200 years ago will definitely make the most outstanding scientists at that time dumbfounded. However, after all, science is different from magic. Clear judgment. Tell me, what is impossible in the world?" Xiao Gang said: "Super-light speed!" Martin said: "Perpetual motion machine!" "Yes. These cannot be done, at least not in the universe we know now."

Feifei said: "There is still immortality, but I can't achieve it. I can't achieve the child-elder's rejuvenation." "Yes, absolute immortality is impossible. Think about it, even the most basic building blocks of matter - protons will be annihilated, and even the universe will perish. How can there be immortality? However, relative immortality Immortality is not impossible, as there is no law of physics that stipulates the lifespan of living things. For example, the average lifespan of humans has increased from 20 years in the ape-man period to 80 years, how much more can it be increased in the future?"

"100 years old!" "200 years old!" The professor smiled: "You are too stingy, if it were me, I would say 1000 years old, 10000 years old." "10,000 years old!" The children's eyes widened. "Don't be surprised. Biological lifespan is controlled by a clock in the genes, and scientists have almost found a way to reset the clock. By the way, the longest-lived organisms in the world are known-not counting those infinitely divisive, Single-celled organisms that never die - is a shrub in Tasmania, Australia, and it (or they) have lived for 45,000 years. There is no reason why humans cannot reach this lifespan. I am not saying that humans are now This can be achieved, but there is a fundamental difference between 'temporarily unattainable' and 'impossible'. It's far away, far away," he said with a smile, "Let's go back to Dugu Xingxing."

After a short pause, he said: "Actually, Dugu Xingxing has not learned the peerless martial arts written by Jin Yong. For example, it can't lift a thousand catties, smash a boulder with its palm, and control a sword with Qi; Iron cloth shirt, diamond mask, etc. Although its performance is dazzling, it boils down to one word: fast. Its superb ability is only because it can respond extremely quickly to the outside world. Think about it, isn't it so? " The four of them raised their faces and thought about it, and nodded in conviction.Xiao Gang said: "Yes, even its tooth-pointing method is not a magical skill, it is like biting an apple that is slowly shaking in front of us."

The professor said: "It just so happens that the word 'fast' can be achieved by modern science. Let me help you review some knowledge of neurophysiology. Animals receive external stimuli and respond by relying on the nervous system in the body. The nerve axis in the animal body The axons are like the telephone wires we use today. Each axon contains hundreds or even hundreds of thousands of nerve fibers, which are insulated from each other and transmit different information. The axons are long or short, and the longest in the human body The most important is the motor nerve fibers in the anterior horn of the lumbar spinal cord, and its end goes straight to the toes, with a length of up to 1.2 meters. The motor nerve fibers in the giraffe's center can reach 2 meters, and the nerve fibers of whales are the longest, reaching more than 10 meters." "Yo, 10 meters!" "Unfortunately, these nerve fibers transmit nerve impulses very slowly. The thicker myelinated fibers are faster. For example, the spinal cord nerve that tubes the movement of limbs in the human body is 20 microns in diameter, and it transmits signals at a speed of up to 120 meters per second; thin unmyelinated fibers will be slower, for example, the nerve conduction speed of some lower invertebrates is only 1/20 meters per second. Organisms are too complex and delicate, when humans do not understand When it comes to its internal mechanism, it is often intentionally or unintentionally regarded as a 'black box', thinking that the movement and mechanism in the living body can surpass the laws of physics. In fact, it is not the case at all. For example, with the above parameters, even elementary school students can calculate the whale The shortest time to respond. Suppose the distance from the whale’s brain to the tail fin is 12 meters, and the maximum speed of nerve conduction is 120 meters per second, then the shortest time for the tail fin to respond is 0.1 second.” Xiao Gang suddenly said: "Oh, no wonder big animals are often not as agile as small animals." "Yes, of course there are also many clumsy small animals, such as worms and snails, which are determined by other factors. But under the same nerve conduction velocity, the response of small animals must be faster, while giant animals such as whales and dinosaurs, It must not be very flexible. The above is just a limit value. In fact, other delays must be added to the reaction time of the animal. For example, the time for the central processing unit (brain) to process the signal should be added; The timing of chemical transmission between adjacent axons (each axon is disconnected, leaving a gap of 20-50 nanometers. Here, the neuroelectric signal needs to be converted into a chemical signal, and then transmitted to the next axon On the axons). In general, after adding these delays, the speed of the animal's reaction is much greater than the value just calculated. For example, a most agile athlete, or a master of martial arts, responds to external signals with the least How long?" Xiao Gang immediately replied: "It's easy to calculate. Based on a height of 1.80 meters and a nerve conduction velocity of 120 meters per second, it takes at least 0.015 seconds for the feet to respond." "In fact, it is much bigger. Take the 100-meter sprinter as an example. Their starting time has undergone the most rigorous training, and it can be said that it has reached the limit of human neural response. What is this time? The starting time of the famous sprinter Green It is 0.134 seconds, Bailey is 0.145 seconds, and Montgomery is 0.134 seconds. Female athletes are relatively better, generally above 0.120 seconds. There is such a rule in the 100-meter race: Anyone with a starting time of less than 0.100 seconds is judged as a false start. This It is based on the following statistical data: the reaction time of human beings will not be less than 0.1 seconds." Martin said with a smile: "0.1 second is fast enough, I think Feifei needs at least 0.5 second." Feifei retorted: "You are only 0.5 seconds. Fat and thin people do not affect the length of nerve fibers, so it does not affect the speed of response, Uncle Zhu, right? There are also many fat people who are very flexible, such as... such as... " "For example, the Supreme Treasure who fought against Xiao Li Feidao is the female giant, who can use the fat on her neck to clamp the flying knife. That is the only time Xiao Li Feidao missed in her life." Feifei knew that she couldn't beat Martin in a war of words, so she had to back out, and muttered in a low voice: "You are the supreme treasure, better than your skinny mantis, and you can't pick bones and bones." Dad Xiaogang shook his head: "No, the response speed of 0.1 seconds is too slow. It is especially difficult to adapt to the modern society where photoelectric signals are used. Taking an airplane with a speed of 3,600 kilometers per hour as an example, in 0.1 seconds, two planes flying towards each other The plane has drawn closer to 200 meters, how can the pilot avoid the collision in time. Even in sports, this speed is too slow. You all know that in a football match, when a penalty kick is decided, the most nervous person is not the goalkeeper, but the goalkeeper. The penalty shooter. Because the goalkeeper sees the football flying out—the brain judges the direction of the ball—sends a signal to the foot—muscle tension—the body accelerates—the ball is thrown, this process must be longer than the flight time of the football. So the goalkeeper rushes It’s understandable not to get the ball, it’s a shame that the penalty shooter can’t score.” Martin wanted to raise the bar again, but after all, it was Uncle Zhu in front of him, so his tone softened a lot: "Uncle Zhu, why are there still so many goalkeepers who can save penalties?" "That's because an experienced goalkeeper is familiar with the opponent's habitual movements and can judge the direction of his shot in advance. More often than not, it is a gamble-no matter where you kick, I will rush in a certain direction. If I catch it, I’m lucky, if I get it wrong, I’m unlucky.” Bai Yi asked: "In other words, Xiao Longnu's overwhelming network will definitely not be able to do it—what about Dugu Xingxing, why can it shoot down bullets?" Professor Zhu smiled and said, "Don't worry, I'll get to that soon. Let me ask you another question. Essentially, what is the signal of a nerve impulse?" Both Ma Tian and Xiao Gang rushed to say, "It's an electrical signal, even elementary school students know it." "Yes, nerve impulses are essentially electrical signals encoded in 0s and 1s. For example, most nerve impulses in the human body have a firing time of 0.5 to 1 millisecond and a voltage of 1 millivolt. Now, I'm going to mention the well-known parameter: what is the speed of propagation of the electrical signal?" "The speed of light! The speed of propagation of electromagnetic signals is the speed of light!" "Yes, the speed of light. In this physical world, almost all electromagnetic signals travel at the speed of light—unfortunately, the nerve impulses that are also electrical signals are picked out, and their speed is only 1/3 million of the speed of light. Too Too late, too bad!" "Why is that?" Professor Zhu shook his head: "Yeah, why? I also thought of this question for the first time when I was your age. If life was created by God, then this God must be illiterate and stupid without any knowledge of physics. You think, He can use 100, 1,000 very simple methods to establish electrical signal pathways that travel at the speed of light in animals - unfortunately this smart God does not exist. The evolution of animals is completely blind, and genes are copied from generation to generation Randomly produce mutations from time to time, and only 1% of these mutations are beneficial to the reproduction of organisms, which are preserved and strengthened and evolved through natural selection from generation to generation. The nervous system is also a completely blind and completely accidental product, so it carries It is not surprising that some congenital fundamental defects. With the evolution of organisms, the general trend of nerve conduction speed is to gradually increase, but due to congenital defects, this increase is very limited: from every invertebrate From 0.05 meters per second to 120 meters for mammals. The evolution of the biological nervous system has taken a wrong path at the beginning, and it is impossible to turn back." Xiao Gang shouted: "Dad, I know, you, Mom and Grandpa Lin must have found a solution!" Xiaogang's dad smiled triumphantly: "It's just a stopgap measure. If I were to redesign the animal body, I would definitely use the best room-temperature superconducting materials to build the neural network, at least silver wire or carbon nanotubes. Of course, this is impossible, so scientists can only find a way based on the existing biological structure. Fortunately, we finally found a way, which happens to be very simple and cheap." "What method? What is the method?" The professor smiled: "I have to keep the specific method secret. Besides, although the method is simple, the mechanism is very complicated. It involves the most profound knowledge of quantum mechanics and the unified field theory of the universe. It will take you about 10 years to understand. At present, you You just need to understand the conclusion—the conclusion is that Dugu Xingxing's nerve response speed has been greatly accelerated, right?" The four children exchanged glances, and also exchanged the most urgent wish, and finally Xiao Gang raised it on behalf of: "Father, can we... also be like Dugu Hero?" The little professor laughed loudly: "It's too hasty. Of course our research is for human beings. Otherwise, we will only cultivate orangutans or cheetahs with superb skills. Isn't that too dangerous for human beings? The famous physicist Hawking once said However, with the development of science, human beings are bound to change themselves. He is absolutely right, that is exactly what we do.” He changed his tone, “However, the nervous system of the human body is too complicated and delicate. It is estimated that it will take another 50 years for the results obtained in chimpanzees to be applied to humans." The children yelled in disappointment: "50 years! That's so long! Then we're out of luck." They all begged: "Uncle, Dad, can you hurry up?" Grandpa Lin poked his head out from the gap in the guard, looked at the group of chattering sparrows with a smile, and winked at Professor Zhu.The professor stood up from the children's siege, and comforted him: "Don't worry, don't worry, even if you don't urge me, I will work hard, even I want to be such a hero. Well, I'm going to work , you should go back." The children are very sensible. Although they are reluctant to part with them, they know that the time of scientists is precious, so they bid farewell to the professor and walked out of the console.As they walked, they discussed enthusiastically: "It would be great if we could catch up with that day." "Born at the wrong time, born at the wrong time." (This is Martin's sigh).Xiaogang said: "The four of us will all come to do this research when we grow up, okay?" Let me be your assistant." Professor Zhu asked a young assistant to send the children away, but the four children ran towards the orangutan in unison.To their delight, the orangutan had also been watching eagerly, growling excitedly as they stepped out of the screen shield.The children ran away cheering, but Xiaogang, Ma Tian and Feifei soon realized that they were being self-indulgent - the enthusiasm of Dugu Hero was directed at Bai Yilai.Xiao Gang rushed to the side of the stands, stretched out his right hand to say goodbye to the orangutan, the orangutan touched it, and pushed his hand away impatiently.Bai Yi saw the clue and said softly: "Let me say goodbye to it." Xiao Gang and Martin raised Bai Yi unwillingly, Xingxing's eyes lit up immediately, and he held Bai Yi's hand—and even kissed him.Ma Tian stared wide-eyed: "Oh my god, it thinks your hand is a delicious sauced pig's trotter." Feifei also burst into laughter.The two professors over there have been paying attention to the situation here.They hadn't interfered when the children shook hands with the orangutan, but this development left them a little embarrassed.Professor Zhu shouted: "Xiao Zhang!" A young man at the side of the stage turned his head, and Professor Zhu signaled him to separate the orangutan from Bai Yi.Bai Yi didn't panic, but was somewhat embarrassed.She reproached gently: "Xing Xing, don't do this, how embarrassing it is for others to see!" Xingxing let go obediently, but when he saw Xiao Zhang approaching with a laser gun, he growled angrily again.When Bai Yi came down, Martin rushed up, stretched out his right hand and shouted: "Xing Xing, come and shake my hand! You're such a bullshit hero!" It was impossible for Xingxing to fully understand the just and stern reprimand, but it blinked, stretched out its hand, and touched Martin copiously.This is enough to satisfy Ma Tianzhi: "Okay, you can understand my words, and you can correct your mistakes immediately. You can teach me." Feifei was jealous, and went up to shake hands with Xingxing.The four left reluctantly.When they walked up the steps, they heard the stars roaring angrily again, looking up to this side.Obviously it is reluctant to part with these children, at least its favorite Bai Yi.Bai Yi smiled and waved to it: "Goodbye, we will come to see you next week!" The kids are gone, it's time to get off work here.As usual, the staff will put the orangutan in an extremely strong titanium alloy cage, and then transport it to its residence.However, today Dugu Xingxing's mood is quite abnormal, it has been roaring in a low voice, making the golden spider silk ribbon crackle.The staff had to show the laser gun, and it reluctantly walked into the cage, and kept glaring at the person holding the gun. Seeing this situation, Zhu Yizhi and Lin Jun were somewhat worried.Zhu Yizhi is actually a believer in the "harmony of man and nature", and has always advocated the harmonious coexistence of human beings and nature.He believes that there is no cruelty in the animal world, and the so-called cruelty is only an instinct necessary for animals to "survive".Not to mention vegetarian animals like orangutans.Its nature is gentle, and although it has been endowed with powerful abilities, it will never become a demon that harms humans. However, the orangutan's "gaffe" to the little girl Bai Yi today is worrying-in fact, it's nothing.This is exactly its instinct.Dugu Xingxing is a mature chimpanzee, of course it has a good impression of the opposite sex (mother chimpanzee), but, after accepting the development of human intelligence, it may have been assimilated by humans unknowingly, shifting its interest in the same kind to the female chimpanzee. On the child—this is a bit embarrassing.Fortunately, Bai Yi has a pure heart, and has always regarded Xing Xing as a silly little brother. From now on, it's best not to let Xing Xing see Bai Yi again. Lin Jun said with a smile: "There was an anecdote in the Nanyang Evening News today. A male ostrich in the park would bow to the knees and salute when it saw tourists—this is the way ostriches court. If you still can't tell the difference between men and women, come together." Knowing that the teacher was comforting him, Zhu Yizhi smiled and waved.Lin Jun said: "Congratulations, this success is century-old." "It's the success of all of us. Tong Ming was very happy in Beijing. But I have warned her not to announce it for now. I think, wait until this Shenli No. 1 is successful in the human body before making it public." "Yes, you shouldn't let the children know today." Lin Jun blamed slightly. Zhu Yizhi scratched his head and smiled: "Yes, but I was too excited at the time." "Since it has basically succeeded, Shenli No. 1 must be strictly protected. There must be someone in the world who covets it. What protection measures do you think will be taken?" Zhu Yizhi jokingly said: "Maybe it's best to train a few human masters like Dugu Xingxing to serve as guards. Before that, I'll take it with me first. Anyway, I'm going to take it soon." "Ok."
