The middle-aged man's name is Su Aijun, an employee of Fengyuan Jiaotong University, and this time he went to the capital, half of which was out on business, and half of him went home to see his parents.

It took a long time for him to wake up from Fang Cai's shock, and looked at Fang Mingyuan in disbelief, he really couldn't believe that such a theory, such an idea, would actually be something that a child could think of. In this land of China, there are not four or five hundred million people who have played with magnets, but two or three billion, why no one thinks of them on the train? Maglev train, the name is good, not only imaged, but also self-explanatory, a little bit of the principle of magnets can understand its meaning. But no one can think that magnetism can be used in this way without anyone piercing this layer of paper!

Su Aijun is also an intellectual after all, although he is not in the train industry, but his mind tells him that the theory proposed by Fang Mingyuan is feasible! It may not be possible for Huaxia to develop a practical maglev train in a short period of time, but it is only a matter of time. If you can really study the maglev train he said, its speed must be more than three or four hundred kilometers per hour! This is definitely a revolutionary step forward for the railway industry! As long as Su Aijun thought that it would only take three to four hours to travel between Fengyuan and the capital in the future, his head couldn't help but be a little foggy, which was no slower than an airplane.

Thinking of this, for Fang Mingyuan, Su Aijun and Fang Cai are completely two attitudes. Just now, I just saw a cute child, and he was very bored on the journey, so he talked to Fang Mingyuan with the attitude of teasing the child. Now, Su Aijun sees Fang Mingyuan as a person who can communicate with him on an equal footing - at least this magnetic levitation theory, this kid thought of it, and said it in childlike language, and he is also in his thirties, but he is not even as good as a child.

Seeing that he came to his senses, Old Man Fang, Old Lady Fang, and Bai Ping breathed a sigh of relief, and they also heard the conversation between the two, although the three of them didn't think that Fang Mingyuan's whimsy had any value, but the middle-aged man in the middle shop was in a daze after listening to it, but he saw it in his eyes, this psychology couldn't help but be a little stunned, this is out of the house, who is not more than one thing is better than one less thing, this driving for a long time, if their children cause mental problems again, the rest of the time will be difficult. If this middle-aged man has three long and two short, this matter will be troublesome. In a short period of time, these people have already regarded Su Aijun as a mentally abnormal person.

What kind of person is Su Aijun, looking at Old Man Fang's eyes, they understood that their performance was probably misunderstood, and they couldn't cry or laugh in their hearts. He jumped down from the middle bunk and said with a smile: "Old man, my name is Su Aijun, and this is my work card." ”

Old Man Fang took it and looked at it, and his face couldn't help but be moved. "Fengyuan Jiaotong University? Are you a teacher at Fengyuan Jiaotong University? "In these years, the common people have special respect for those who can enter the university, whether they are studying or working. Moreover, Fengyuan Jiaotong University is also an old brand of university in Qinxi Province, and it has been established since the Republic of China. Now in Huaxia, it is also a well-known brand.

"Haha, sometimes with occasional lessons." Su Aijun smiled.

Old Man Fang returned the work card to Su Aijun, which made him feel much more at ease, and Mrs. Fang and Bai Ping also had a lot of natural faces, and they also had a smile on Su Aijun.

"What the child just said is very reasonable, and it touched me a lot. Can I continue to talk to him? Su Aijun said politely.

"Let's talk, let's talk, the child is whimsical, Mr. Su doesn't want to laugh at him!" Old Man Fang was secretly happy in his heart, if his little grandson could have a good relationship with this university teacher, it would also be a good choice to be admitted to Fengyuan Jiaotong University when he grew up in the future. There are also people to take care of in the school, it is close to home, his second uncle can also take care of it nearby, and if he wants his grandson, he can go to Fengyuan to have a look.

"Where, where, the children's ideas are very interesting." Su Aijun said with a smile, "It's rare to see such imaginative children." Old man, you are well educated! ”

"That's a smart doll, he loves to read since he was a child, and we workers who don't know a few people in college haven't educated him much." Old Man Fang said with a smile.

"Fengyuan Jiaotong University?" At this time, Fang Mingyuan was also surprised in his heart, he was really lucky, he bumped into a university teacher with a few casual words, no wonder this person is so allergic to maglev trains?

"My name is Fang Mingyuan, and I am in the second grade this year." Seeing Su Aijun's gaze turned, Fang Mingyuan hurriedly reported to his home, "Please don't call me a child or a little guy." Little children also have dignity. "Since you bumped into it, you must leave a deep impression on this one, and maybe when you can use it in the future! College teachers are in eighty-four years, which is definitely a scarce resource! Fang Mingyuan had already made a decision in his heart in an instant.

"Ah......" Su Aijun didn't know what to say for a while. If you paraphrase the words of later generations, it is Fang Mingyuan's words that thundered Su Aijun a lot.

"Xiao Mingyuan, can you tell my uncle, what are the benefits of this train speeding up?" The two casually talked about it for a few words, and the topic returned to the speed of the car.

"Of course, the speed of this train is good, first, our country is vast, from south to north and from east to west, there are thousands of kilometers, if you take the train, you have to sit for several days and nights, we sit in sleepers, are so uncomfortable, those who sit in hard seats, isn't it even more uncomfortable. Riding the train once is like suffering a secondary sin. If there is an emergency in the country, such as floods and droughts, it is necessary to mobilize materials in large quantities across provinces, and it will take several days to leave, and it is difficult to quench the thirst of the water that is far away! ”

Su Aijun's eyes lit up, the little guy said it well, it is indeed this principle. Moreover, if the speed of the vehicles can be raised, the first to benefit is the military columns, and the speed of large-scale transfer of troops can be greatly improved. In this way, it will have an immediate effect on the improvement of China's military strength. If the entire army, regardless of the province in which it was originally located, could be guaranteed to move to any point where the railway line could extend within three to five days, its deterrent effect on the surrounding countries would be stronger than that of a few more army divisions. At this time, the war between Huaxia and Baiyue was still going on, as an adult, how could Su Aijun not care about the military?

"Second, it's also to save money!"

"Save money? What about weishenme? Su Aijun asked a little confused. It was the first time he had heard that increasing the speed of a train would save money. The faster this speed, the higher the ticket price, and the more expensive it should be. So ship fares are the cheapest, and airfares are the most expensive.

"Uncle, let's give you an analogy. If you want to travel from Fengyuan to the south, it will take about three to four days by train, right? Let's count it as three days. Go, you want three days, come back, you need three more days. You only need to travel once a month, which means you have six days on the road. You are a teacher, and although you can't do much in the car, you can still read books and enrich yourself. Fang Mingyuan looked at the noisy carriage and pouted, "But I don't have much hope for the effect of this reading." But what if it's a factory director or a jishu backbone? For six days, they couldn't do much. However, if it only takes one night to get from Fengyuan to the south, then you can get on the bus to sleep, get off the car to run errands, and you can use these six days. I don't know how much your monthly salary is, but according to my father's salary, such a month can save six or seven yuan, and there may be hundreds of thousands of people taking trains across the country every day. ”

Su Aijun was stunned for a long time, it turns out that the account can still be calculated like this? This was something he had never imagined.

"Third ......"

"Fourth ......"

"Fifth ......"

Later, Su Aijun's gaze at Fang Mingyuan was already a little numb. I am also an adult who has gone to college, and in my eyes, the speed of the train is nothing more than a thing, but in the mouth of this little guy, the speed of the train has become a major event for the benefit of the country and the people! The impact is even more profound!

The logic of the little guy is very clear, although it is all fairy tales, but it has already explained the problem.

"He's in the second grade of elementary school, seven or eight years old. I, a college graduate, was thirty-two years old. But how can this gap between people be so big? Su Aijun wanted to hug his head and shouted.

This little guy is a genius!
