The mountain peak that walked out of the forest took an ox cart on the official road, and it was supposed to be the next day to get to the capital, but the villagers of the ox cart couldn't stand the mountain peak telling him all the way to what heroic deeds, so they were stunned and swollen the cow's buttocks, and it only took half a day to arrive outside Lin'an City before dusk. The mountain peak that jumped out of the car was just about to thank the villagers, but it turned out that the person was missing.

The villagers in the ox cart, who were already a few miles away, wiped the sweat from their heads, thinking to themselves whether this kid was really stupid or bold? If you tell me some deeds in the rivers and lakes, I can still talk to you, but you actually asked me if His Majesty the Emperor really wears gold underwear? That's it? This kid actually said that His Majesty the Emperor is not stupid? Why is there a famous general, General Fei, why don't you let General Fei be the emperor? Isn't it asking others to hear about it?

How did Zhang Shanfeng know that his problems just now were disrespectful, and he would be imprisoned or even beheaded. However, standing under the city gate at this moment, he didn't expect that there were so many people entering Lin'an City every day, and he was stunned to line up to enter the city for almost half an hour before it was finally his turn.

Zhang Shanfeng stood in the city gate, looking at the high-rise buildings in Lin'an City from afar, and the endless flow of people, and somehow there was an indescribable familiarity in his heart.

"Lin'an! I'm coming. Zhang Shanfeng roared, startling the people in front of him and behind him. The two soldiers guarding the gate were stunned for a moment, and then smiled, knowing that another stupid boy from the countryside had entered the city.

"Hey, that stupid boy from the country! A soldier stretched out his hand in front of Zhang Shanfeng's face.

Zhang Shanfeng was stunned for a moment, and asked incomprehensibly, "What money?"

"What money?" The soldier glanced at Zhang Shanfeng with disdain, thinking to himself that this kid wouldn't have no money on him, right? "Entrance fee, 10 wen. ”

"10 Wen? Zhang Shanfeng took out his purse and began to look for money, then felt that something was wrong, looked up and asked, "Do you want money to enter the city?"

"Nonsense, do you think Lin'an City is your rural place? This is at the foot of the Son of Heaven! The scenery here is beautiful, the people are outstanding, and harmony and friendship are everywhere. Reckless boys like you who have just entered the city are the most likely to destroy public property, such as carving something on the wall to visit here, throwing confetti everywhere, etc., there are too many uncivilized phenomena. The soldiers defending the city were full of witty words, and the peaks they talked about were stunned.

"This ......" Before Shanfeng could speak, the soldiers defending the city continued: "Even if you don't know how to do those things, since you have come to Lin'an City, you must have a zeal to love Lin'an City. You think, it costs money to get rid of the city's psoriasis and keep the city clean. Although you only paid a small 10 yuan, you also contributed to the city, and all the people of Lin'an City will thank you for your efforts. ”

The soldier unceremoniously took 10 cents from the purse of the mountain peak, and then threw the purse back to him.

"Come into the city, don't block the city gate, you are affecting the traffic, be careful I will fine you 20 wen." "The soldiers put the money in their pockets and drove the mountain into the city.

Shanfeng stood stupidly under the city gate, still surprised by the eloquence of the soldiers guarding the city, but looking at the tall buildings in Lin'an City and the endless crowd on the street, he was thrilled at this moment.

It turns out that this is Lin'an City, and this is the city where the emperor lives. "Bah, that's fucking big. ”

"Spitting, a fine of 10 yuan!" A soldier with a red armband suddenly rushed to Shanfeng's side and took 10 yuan from his purse before Shanfeng could come to his senses.

"Could this be the shadowless hand that Old Man Du said? Sure enough, a big city is a big city, Crouching Tiger, Hidden Dragon. Shanfeng actually laughed happily, and he didn't know if he was happy or stupid.

After that, the mountain peaks are like dirt buns entering the city, and everything you see feels fresh, wandering around in Lin'an City, and you have to go up and touch it if you see something you haven't seen. A few times, I almost wanted to touch a few girls who looked better than Guo Xiang, but fortunately he didn't really do it. Otherwise, as soon as he entered Lin'an City, he would have to go to Lin'an Prison for a few days.

I don't know if Guo Xiang would be half angry if he knew that this kid would forget her words as soon as he entered the city.

When passing by the West Lake, I washed my feet. Fortunately, the mountain peak ran fast, otherwise he would have to pay a fine of 10 yuan for polluting the water quality of West Lake.

What kind of sugar gourd, noodle man, the mountain peak is the first time to see it, and it doesn't matter how much money you have, you buy it when you see it. also bought a mask of Sun Wukong to play with, although he didn't know what Sun Wukong was. However, the mask seller was enthusiastic, and when he saw that he didn't know, he explained to him.

"This Monkey King is a spirit monkey that popped out of a spirit stone left by Nuwa after making up for the sky in mythology. Speaking of spirit stones, I have to mention my string of Buddhist beads, which is the same stone as the spirit stone back then, and it was also opened in Shaolin Temple a year ago. At the beginning of next year, I will be the main writer and Shaolin Temple brother together to publish a Buddhist novel "Dare to ask where the Buddha is", I will use this Wukong to create a positive energy image, gods and Buddhas bloom, promote my Song Dynasty culture, please pay more attention. ”

The mountain peaks applauded, and they originally wanted to buy Buddha beads, but who knew that they were just about to pay, and the hawker flew as if he grabbed his own car and ran. Two soldiers with red armbands shouted that they were setting up stalls without a license, and they chased after them. The peddler also ran backwards and fast, pulling the cart through the crowd on the street, and the masks and groceries on the cart did not shake at all.

"Eat my exhaust!" the peddler shouted at a beautiful turn around the corner, lifted his ass, and disappeared with a cheerful face. The two soldiers who had just arrived at the corner of the street covered their noses and looked at the dark alley where the other party's figure had disappeared and was stunned in place, and the taller soldier stomped his feet angrily, "What is the origin of this guy?

The other soldier fanned his nose with his left hand, and with the other hand he took out a slender cinnamon roll from his armor and put it in his mouth, then looked up and sighed. "He used to be a tofu seller. ”

"Huh, a tofu seller running so fast?" the tall soldier stomped his foot in disbelief. "I came out on duty today, and I was wearing chicken hooves. No wonder he is so angry, this "chicken hoof" is the latest embroidered small scalp shoes from a well-known shoe store chain in the country.

The short soldier didn't pay attention to the tall man's shoes at all, looked down at the ground, and said lightly: "The jade yellow eel on the Jade Emperor Mountain ......"

"Bai Zhihui under the white fat legs!" the tall man was startled, and the unconvinced look on his face had turned into confusion. "Both are legendary old drivers of the Biao car. The question is, is this kid really a jade eel, the one who created the fastest legend of Jade Emperor Mountain?"

"You can't be wrong. The short man pointed to the ground, and the tall soldier gasped as he looked. As far as the eye could see, there were bluestone bricks paved with bluestone bricks half a foot apart, and the bottom was empty, just under the rain eaves of the roadside house.

"What is this?"

"You don't know it, this is the legendary drain bend!"

"Ahh

"Oh, sorry. It's me, I don't know. Shan Feng raised his hand and appeared behind the two soldiers who were bending down to look at the drain. The two soldiers were startled by the sudden sound of the mountain and flashed to the side. found that it was not the above leader who did a spot check, and he also relaxed to explain to him.

"Do you see there are two ruts in the ground?"

"Hmm. Shanfeng nodded.

"You saw that the bluestone slabs were empty in the middle, and he would have slowed down when he got here because the wheels were in neutral, but he didn't, why?"

"Why?" the short soldier continued, as the mountain peak kept up with the rhythm of the inquiry.

"Here's why, you see this rut to get close to this bend, and the rut on the left is gone. It shows that his left wheel did not touch the bluestone slab of the drain. Isn't that right?"

"Yes!" Peak continued to nod.

So how did he do it...... He's ......"

"How?" asked Shanfeng, and the two soldiers reminded him that the timing of this inquiry just now was not good, so pay attention next time. The mountain still nodded.

"It's not as simple as lifting the left side of the car, if you need to manually lift the car with the force of your feet, then it will definitely slow down, but he didn't slow down. Rather, it is better to say that he accelerates, because the centrifugal force generated by the steering at high speed, and the centrifugal force will help him lift the left wheel when turning. The short soldier continued.

"But if you let the centrifugal force go unchecked, it will overturn. In order not to roll over, he needs to provide reverse pressure, so he needs to lean to the left and maintain his speed. So, how did he do it?"

The tall soldier took over the commentary and crouched down at the entrance to the bend, where he squatted there was a mark that was noticeably wider than the rut, the mark was very short, and the entrance to the bend appeared and the exit of the bend ended, right opposite the corner of the house.

He lifted his left foot, and the person fell to the left, using the downward gravity he generated, against the centrifugal force of the turn. When exiting a corner, the lateral G-force generated by friction and the integration of the other person and the car will not fall to the left when entering the corner, but will be straightened. This shoe mark is the best proof of this. ”

"I was able to do it all in an instant, and I was able to take the time to spray exhaust fumes. It's amazing. Both soldiers applauded.

"Understood, do you have any questions?" The two soldiers seemed to know that Shanfeng must have questions, waiting for answers.

"Oh. Some. ”

Shanfeng looked up and thought about it.

"What is a rut?"

"That's the problem!"

It turns out that the rut is the indentation of the wheel left by the vehicle after driving on the road. After receiving this encyclopedic answer, Shanfeng said goodbye to the two soldiers with satisfaction.

The two soldiers waved their hands side by side as the mountain peaks disappeared into the twilight, and the tall soldier tilted his head and asked, "What is the centrifugal force you just mentioned?"

"Oh, I'm talking nonsense, I don't know what the hell it is. The short soldier looked up at the tall soldier.

"And what is that gravity and lateral G-force you just talked about?"

"Oh, I'm talking nonsense, too. ”

The two men looked at each other for a few seconds before they began to laugh with their stomachs in their arms. I don't know how much they laughed, the two of them wiped away their tears and continued to patrol work.

"What the hell is a drain bend?"

"Oh, I'm talking nonsense about that, too. ”

"Is it okay to talk so much about this chapter?"

"It's okay, it's Lin'an here!"

"Yes, this is Lin'an!"
