Xiao Nan's explanation calmed everyone present, it was obvious that most of the girls in the team listened to it in a fog, although they were all female drivers selected through cruel auditions, but female drivers are female drivers after all, and the best of them may be able to reach the driving level of male drivers, but it is too extravagant to expect them to understand the operating principle and structure of locomotive engines to the point of Xiao Nan- After all, if it weren't for the professional, even the male driver might not be able to understand all what Xiao Nan just said.

However, Lao Tian and several technicians who came to see the excitement were quite appreciative of Xiao Nan's explanation, and Lao Tian's small eyes narrowed into a slit with joy, obviously a "I have found a treasure" expression.

"I said Cheng girl, what did you study in college?" Lao Tian couldn't help but ask with some curiosity.

"Decoration design...... Oh yes, I studied fashion design at first, and then I changed to a major in business. Xiao Nan's answer was serious.

"I thought you were a professional in internal combustion engines, but you were actually a layman!" Lao Tian was taken aback this time, he obviously seemed to be more and more interested in Xiao Nan. "If you don't look inside the engine, you can know so much information just by the driving feeling, and it's difficult for a master who doesn't repair a car to do this, who did you learn from?"

"I learned it myself~ When I just came out of college, I bought a Honda CB400 street sports car with the first few months of work, I don't know how many hands I poured, this car has all kinds of problems and all kinds of bad things in my hands, every time I travel with friends, I must have lost me on the road, I had no money to change the car and could only repair it, repair it once or twice, three times or four times...... In the end, even the car repair master was annoyed, and persuaded me to sell the car as a tattered and I was reluctant, so I simply threw the tool to me and let me repair it myself, and I naturally understood it after coming and going......" Xiao Nan spread his hands and said helplessly: "The so-called long-term illness and medical treatment is what I ...... said"

Lao Tian nodded approvingly, and said with emotion: "It is said that interest is the best old master, it seems that this is not false at all!"

"Then you also practiced your driving skills by yourself?" Xiong Mi asked. Xiao Nan's explanation of the change in the high-speed performance of the engine just now, even she didn't understand it, because the cars she drove since she was a child were all prepared by others, and the mechanic was responsible for repairing the problem, and she didn't know much about the operating principle and structure of the engine as well as Xiao Nan, and the locomotive was no different from a racing horse for her, she just needed to know how to control it.

"Yes, I practiced it myself. Xiao Nan said: "When I just learned to drive a locomotive, I can't wait to sleep with the car in my arms at night, and I drove to Baoquan Mountain with my friends on a day off, because at the beginning my car performance was the worst, in order to catch up with them I had to work the cornering technology, in order to barely be thrown off by them, and then I changed to a good car, they couldn't keep up with me......"

Xiong Mi frowned slightly, she didn't fully believe what Xiao Nan said, she could practice to this level by herself? I feel that she is not much worse than her master, and her understanding of the operating principle and structure of the engine is even deeper than that of her master, can she be so powerful without anyone to teach her?

At this time, the one who had not "spoken" stood up, and she used gestures to tell Xiao Nan that she had not answered her second question.

Xiao Nan scratched his head unconsciously, and the second question was how he used the rear wheel to slip and flick his tail through the first corner, so as to establish the lead early. She thought about it for a moment, took Lao Tian's model locomotive from Qing Ran's hand, put away the model's bracket and placed it directly on the table.

"Well, I'll now answer my second question. First of all...... Let's look here. Xiao Nan let go as soon as he spoke, and the model locomotive that had put away the bracket fell down. "See, the locomotive is a kind of static and unstable motorized vehicle, which can only achieve a relatively stable state by constantly finding balance in motion, which is different from the car. Why do I mention the static instability of the locomotive, because one of the most important techniques I used when I was passing the first corner was to try to find a sense of balance when the locomotive was in a state of extreme instability. ”

Speaking of this, Xiao Nan raised her eyes and looked at her "audience", in addition to Qing Ran and Xiong Mi, the girls of the team and the technicians led by Lao Tian also stared at her with wide eyes, obviously the topic now is more attractive than the one just now.

"Xiong Mi, suddenly, do you two know how to burn tires?" Xiao Nan asked. (Note: Tire burning refers to the high-speed rotation of the driving wheels of the locomotive or automobile, which causes the tires to rub violently against the ground, resulting in high temperature and smoke from the tires, and in serious cases, it may even lead to tire burning)

Both girls nodded. "Yes, what's the matter, do you want to watch it now?" Xiong Mi's tone seemed to feel that he was being underestimated.

"No, no, no......" Xiao Nan smiled and waved his hand at her: "This kind of skill will definitely not be difficult for high-level drivers like you." So, can you get the car to move in a burning tire?"

Qingran and Xiong Mi glanced at each other, thought for a moment, and nodded again. "It shouldn't be difficult, I've encountered this situation when I was playing blind before, when the front wheel brake is locked, the body will often sway from side to side when the rear wheel burns the tire, and if you deliberately don't correct it, the rear end will be thrown to the side, and at this time, as long as you have a good balance of the car, you can spin in place. ”

Xiao Nan nodded approvingly: "Yes, this is actually what everyone often calls drifting, which is generally mostly used for cornering of four-wheeled cars, and very few locomotives, do you know why?"

"Because cars have four wheels, right?" Han Zheng, who was squeezed into the outskirts by everyone, suddenly interjected, and it seemed that he was quite interested in Xiao Nan's topic. "The car drifting is wrong, at most the rear of the car is thrown on the parapet, just like the Maserati who raced with you last time, the driver will have nothing to do as long as he wears a seat belt, but the motorcycle you drive is different, the motorcycle only has two wheels in the front and rear, and if you don't drift well, you have to take yourself and the car to drift out, which is much more dangerous than a car. ”

"Yes, Manager Xiao Han is right. Xiao Nan picked up the model locomotive, compared a quick forward rush in the air and suddenly flicked the tail and drifted, and said to everyone: "In fact, the so-called drift is to artificially break the grip of the rear wheels of the locomotive, so that the rear wheels of the locomotive slip on the ground." We all know that the stability of the locomotive should be achieved by grasping the ground through the tires, especially when doing the cornering action, the reason why we can tilt the body to the ground at a large angle without slipping is because the huge centrifugal force generated by the body when cornering can be converted into grip through the tires, once we let the locomotive in a drifting state, this grip is broken by us on the initiative, the rear wheels of the locomotive are like driving on the ice, and the body balance needs to be adjusted extremely carefully and accurately……”

Saying this, Xiao Nan looked at Xiong Mi and Qing Ran, and said very seriously: "So, even if you master this technique through practice in the future, I still very much recommend that you use it in competitions, because this action is too dangerous, and everything will become unpredictable from the moment your rear wheel starts to slip......"

"Then why can?" Xiong Mi frowned, obviously she didn't hear Xiao Nan's words in her heart. "If you can, then so can I!" she said, unconvinced.

Xiao Nan shook her head slightly, and said to her quite sincerely: "The reason why you say this is because you don't know it yet, and when you learn this technique, you will understand its uncertainties...... Let me put it this way, I used this technique in the game just now, and I was actually gambling......"

"Bet?" Xiong Mi couldn't help but be stunned.

"yes, I'm just gambling...... If I succeed, I will be able to win the two of you by the greatest advantage, and if I fail, ......" Xiao Nan smiled faintly at Xiong Mi and Qingran: "If I use the conventional cornering method, even if I can win, I may not have much advantage over you, because you are too good......"

Xiao Nan's last sentence was something Xiong Mi never expected, Xiao Nan did not boast of himself as a winner, nor did he elevate himself to demean the opponent, but took the opportunity to praise Xiong Mi and Qi Ran for being very good, Xiong Mi was still unconvinced just now, and suddenly blushed, opened his mouth but couldn't say a word.

"Cheng girl, you remind me of a person...... Lao Tian, who has been a bystander for a long time, suddenly interjected with a smile.

"Who is it?" Xiao Nan asked curiously.

"Honesty. ”

"Qingcheng!" Xiao Nan couldn't help but feel a stir in his heart when he heard this familiar name. How could she forget this name, if it wasn't for the match between Baoquanshan and Qingcheng, how could Xiaoting be injured, and how could she have transformed into what she is now?

"Yes, Qingcheng, used to be one of the main drivers of our Zongxin team. Lao Tian saw that the expression on Xiao Nan's face was different, the corners of his eyebrows raised, and asked, "What, do you know him?"

"No, no, no, I've only seen his name on the locomotive magazine. Xiao Nan hurriedly denied it. "Didn't he win several national Grand Prix?"

"yes...... At that time, Lao Zuo was not the president of the company, he and Qingcheng, as well as Yuexi, who was the master of Mi Yatou, partnered together and won the championship and runner-up of many national Grand Prix...... "Lao Tian's eyes are long, as if he has returned to his youth:" At that time, Qingcheng was very similar to you now, he was very familiar with locomotive hardware, almost able to use half a technician, and his personality was similar to you, he usually didn't like to show off, he didn't know when he would suddenly go crazy, he had a strong desire to express himself deep in his heart, and he was a typical **young man~"

"**Young ......" Xiao Nan just took the opportunity of Lao Tian to speak and took a sip of water, but it almost sprayed all on Lao Tian's face. "Tian Gong, are you praising me or belittling me?"

"Of course it's a boast! Do you think anyone can let me compare him to Qingcheng?" Lao Tian glared at his little eyes and said with a pretense of majesty. "You must know that at the beginning, even Lao Zuo at his peak won more losses and fewer wins when he played with Qingcheng, so Lao Zuo won more runner-up titles than champions......"

"Okay, it's really a boast......," Xiao Nan shrugged helplessly, she had nothing to do with this senior who had a lot of status in the unit.
