Wheels have been around since ancient times.

However, rubber tires were not invented by Scottish civil engineer R.w. Thomson until 1845, and now civilization has only been rebuilt for 50 years, and it is normal not to master some technology.

Lin Feng secretly speculated, and still had an inexplicable sense of superiority in his heart, after all, repairing tires is a very simple matter, except that he doesn't know what glue to use and what kind of tire polishing to what extent, he is really competent.

Boss Wang stood up and sighed: "Forget it, go back and take the car to Xiaoqiao Town to buy a tire and come back, I am busy in the store all day long, I don't know when I will be free?" ”

A middle-aged man next to him interjected and said, "Lao Wang, I am guilty, the fare is about 20 yuan for coming and going, and 800 yuan for a tire, which is enough for ten catties of meat." ”

Boss Wang said helplessly: "What can I do, we don't sell tires in the town, and this tire can't be repaired like electrical appliances, and it can only be replaced if it breaks." ”

From their conversation, Lin Feng found that the price of meat was only between ten and twelve yuan, which seemed to be similar to China in the 21st century, that is, tires were more expensive? It should be so, after all, rubber tire technology is backward.

Just thinking about it, Boss Wang shouted again, "My shop is busy, which villager went to Xiaoqiao Town to bring me a tire back, in addition to the fare and tire fee, I will give an extra twenty yuan, which is considered a running fee." ”

Several aunts were ready to move, and no one was embarrassed to respond, so many people were present, and everyone wanted to save face.

Lin Feng smelled the fragrance of the meat buns next to him, and couldn't help swallowing his saliva, there was no money in the bag, hearing Boss Wang's shout, he suddenly had an idea, and hurriedly accosted: "I! I! Then he raised his hand.

More than a dozen people present looked sideways, and a few aunts who were interested in purchasing were preempted, with annoyance on their faces.

A middle-aged woman may know Lin Feng, and said with a smile: "Yo, Xiaofeng, why don't you go to Xiaoqiao Town with your father today?" Yesterday, I heard your dad say that you want to go to the field, don't you go to play game consoles again, right? ”

Lin Feng frowned and didn't care, the original owner of his body didn't seem to have a good reputation in the town.

Boss Wang spoke, he held up his glasses, and asked with a smile: "Xiaofeng, go to Xiaoqiao Town?" Okay, then Uncle will give you the money and go back and help me buy the tires back. ”

The others didn't take it seriously, but Lin Feng's next sentence made everyone stupid!

Lin Feng walked to the side of the bicycle and said in an astonishing voice: "The tires are not bad, you don't need to replace them with new ones, I'll just make it up for you." ”

There was silence!

Everyone seemed to have heard something incredible!

After about a second, an old man blinked and said, "Xiaofeng, what are you talking about?" ”

The middle-aged woman just now looked at Lin Feng with strange eyes, "Supplement?" How to make up? Do you still want to patch up your clothes like that? I have been in charge of the Jinghai Town Civilization Revival Guild for more than ten years, and I have never said that bicycle tires can be repaired! ”

It turned out that she was a member of the Civilization Revival Guild.

Boss Wang stared at Lin Feng for a while, his eyes were full of disbelief, maybe he was very good at being a man, and he still smiled and said: "Cheng, then you make it up for me, if you want to make it up, I'll give you fifty yuan, and it's okay if you don't make it up." ”

Seeing that the other party was on the road like this, Lin Feng squatted down and touched the shriveled tire, "Okay, thank you Uncle Wang." As he spoke, he instinctively said "Open Sesame" in his heart. After reading it, he regretted it,, in front of everyone's eyes, how to explain a mechanical sound and virtual shielding later?

Unexpectedly, more than a dozen people at the scene turned a blind eye to the virtual screen and Noah's mechanical sound, as if they hadn't heard or seen it at all.

Lin Feng was wondering, and Noah's voice came: "Master rest assured, this intelligence uses cutting-edge camouflage technology, and it will not be discovered unless it is in a specific environment." ”

Hearing this, he breathed a sigh of relief, and then spent 10,000 yuan to buy the "Bicycle Tire Repair Technique", and the white words on it instantly turned red. Although he had never eaten pork or seen a pig run, Lin Feng didn't know what glue to use to repair tires, let alone how far to polish before he could apply a patch.

When he learned the technique, he saw a line of words appear on the virtual screen: turn the car upside down, remove the inner tube, and use a screwdriver to insert it into the tire from one side......

It clearly describes various bicycle tire repair methods.

Lin Feng knew it in his heart, and was about to give orders.

Suddenly, a familiar voice came from behind, it was the cheap father, "What are you doing squatting here?" Go home and eat! ”

Although the tone was not good, Lin Feng inexplicably moved in his heart, the cheap father chased him out so quickly, I am afraid that he didn't eat it, otherwise it was not so fast, obviously he was reluctant to let his son starve, and he couldn't help but think of his father in his previous life, who was also a knife-mouthed tofu heart.

Boss Wang's voice came, "Lao Lin, Xiaofeng said that he wanted to repair the tire for me, don't be so impulsive in your tone, don't blame the old brother for saying you, he is usually not very careful, but there is also a problem with your education method." ”

Lin Feng turned his head to look at it and found that his father's face was not very good.

"Tire repair?" The father asked rhetorically, obviously questioning, but considering that there were many people present, he wanted to save some face for his son, so he didn't say anything more.

"Can you make it up?"

"Xiaofeng, if it doesn't work, let Boss Wang buy it again."

"Yes, isn't it just fifty yuan, let your father give it to you, there is no need to find Boss Wang happy."

Seeing that he was slow to move, everyone talked about it, and it was clear that they didn't believe that bicycle tires could be repaired.

Hearing the words of the villagers, Dad's face was already black and a bit like the bottom of the pot, and he was going to make a fool of himself with the bastard boy today!

Tire repair?

How can it be!

I've never heard of anything like this!

No wonder everyone reacts like this, it has only been 50 years since mankind defeated Noah, and a lot of science and technology have been lost, in the process of rebuilding civilization, the upper class people are busy with cutting-edge scientific and technological research and development, and the people at the bottom are farming, going to work, and they are still in the food and clothing line, how can they have time to study whether expensive bicycle tires can be repaired, two thousand bicycles, but not everyone is willing to buy them, luxury.

Just when everyone was waiting impatiently, Lin Feng spoke, "Get me a basin of water, fill it up, and find a file, scissors, pumps, old tires and rubber water." ”

"Huh?"

"A basin of water?"

"What do you want these things for?"

Everyone was obviously puzzled, but they didn't know if it was driven by curiosity, or to give Lao Lin face, or to make it up, taking advantage of this time, Lin Feng touched the tire a few times, and found a small steel wire and lost it, otherwise it would have to be punctured after repairing.

Then, in everyone's slightly urging eyes, Lin Feng did not hurry to pump the tires into full air, put them in the basin and began to look for the parts that were punctured and leaking.

Seeing this, Boss Wang was curious: "What are you doing?" ”

Everyone is very strange, is the second boy of the old Lin family really capable or is it tricky? Didn't you say you wanted to patch it? What do you do when you fill up your tires and put them in the water?

Lin Feng casually explained, "Before making up for it, I have to find the bad place first." ”

Everyone suddenly realized, how can they make up for the bad if they don't find it? But the air leak is so small, it's not easy to find!

As soon as he finished thinking about it, he heard Lin Feng's calm voice, "Found it." ”

The dozen or so people present all looked at it and found that the tires that were pressed by Lin Feng in the basin were bubbling and bubbling!

"Huh? How did I not expect gas to create bubbles in the water? The middle-aged woman said: "If the tire is broken, it will leak when it is full, and bubbles will naturally bubble out of the water." ”

Some things are very simple, but others don't say they can't think of it, and when they understand the principle, they will suddenly realize, oh, it turns out that it's so simple, and now Lin Feng repairs bicycle tires for everyone, because no one in this era invented bicycle tire repair, naturally I feel surprised at first glance, and I feel simple after being surprised.

For example, Lin Feng's Meituan and Didi taxi in his previous life were actually a very simple design, but before they appeared, who would have thought that ordering food and taking a taxi could still be like this? It's the same thing he now is tinkering with his bicycle tires.

Dad looked at his unobtrusive son in surprise.

Lin Feng nodded, and the movements of his hands did not stop, "Normal physics knowledge." As he spoke, he made a mark, went through the tire water again, and found that there was nothing bad, so he deflated, and then cut a small piece of the old tire with scissors, and then picked up the file and polished it on the tire.

Boss Wang humbly asked, "Why do you want to polish tires?" ”

Lin Feng didn't raise his head, "The surface of the tire is too smooth, which is not conducive to patching, and otherwise the surface will be uneven after repair, which will damage the tire." ”

I don't know who came from the crowd and said, "I see!" ”

An inexplicable light flashed in his father's eyes, as if his son was not so out of tune, at least the physical knowledge was okay.

After the polishing was done, Lin Feng wiped the surface of the tire, polished and cut the small piece, and then brushed some rubber water on it, and found the right position to paste it.

This time, it was the middle-aged woman's turn to ask, "Why did you specify that you should use rubber water?" Can't you use other glues? ”

Oh, yes!

If you want to glue, why can't other glues?

Whether it's Boss Wang, Dad or others, they don't quite understand.

Lin Feng pressed down hard, "Generally, glue is brittle and has no toughness and ductility after drying, while rubber water will not. Finally, he put it in his leg and slapped it on the back of a file a few times, stood up and asked, "Does anyone have a lighter?" ”

Someone hurriedly pulled out a diesel lighter and handed it over.

Lin Fengxin said that this guy is quite rich, it is not a disposable lighter, he played it casually, baked it at the patch for a while, filled the tire again, put the patch in the water, and sure enough, there were no bubbles, he stood up with satisfaction and said, "It's done." "But I found that everyone had different expressions on their faces!

The middle-aged woman can't take her eyes off and show a strange light!

Dad was blindsided, and he turned his head to one side, "Lao Wang? This...... Tires don't flat? ”

Boss Wang looked at the tires that were still immersed in the water and stammered, "Okay...... It seems like that's the case! ”

A young man in the crowd had already run over, pressed the tire into the water as if he didn't believe it, and found that it was really no longer bubbling, he was surprised: "Xiaofeng, how did you come up with this repair method?" It's really not leaking! ”

Lin Feng smiled slightly, "I'm just applying what I've learned, and I just have some imagination." ”

Apply? What a simple word. But you don't just apply what you've learned, others can't think of tire repair, how can you just think of it! The middle-aged woman also wanted to ask Lin Feng if she had seen the tire repair technology from which book, but when she thought about it, she knew that it was impossible, she had worked in the Civilization Revival Guild for more than ten years, and had never seen a record, generally if there was any new invention or restoration of the technology hundreds of years ago, either go to the Civilization Revival Guild to register a patent, or submit it to the guild to receive the invention award every month, that is to say, there should be a record on the computer of the Civilization Revival Guild, but there is no record of bicycle tire repair at all!

I'll go! What's your brain??

Lin Feng's hand shocked everyone present!

Especially the cheap dad is even more shocked, as if he doesn't know his son anymore!
