I do research in ancient times

Because he went back wearing new rubber shoes, Zhang Sanniu has been popular among his colleagues for a long time.

His mille-layer soles were originally thicker than other people's soles, but now they are coated with a layer of rubber, and the style suddenly becomes outstanding.

The gray rubber perfectly connects the sole and the upper, and the bottom is also printed with some non-slip patterns by careful Ning saws. It is soft and elastic when walking, and there is no trace of hand-stitching at all, as if it was made It will be integrally formed.

The rubber rounded the smoothness of the shoe lines, and also slightly increased the thickness of the sole, making Zhang Sanniu, who was not originally tall, much taller.

Has a person who has been simple and simple for most of his life ever been so fashionable? !Wherever he goes, people ask about Zhang Sanniu's shoes. He has really led a trend!

In the past few days, Chief Guard Zhang wore new shoes and walked in Jiuling City every day, raising his legs high and lowering his feet lightly, and the angle of the horoscope was much wider than before.

Now he enjoys all kinds of envious and jealous eyes. When he gets home, he carefully takes off his shoes, washes and wipes them carefully with clean water and a clean cloth, and then puts them in the cabinet in the room solemnly, not forgetting to lock it.

His mother-in-law was angry when she saw him like this.

After spending most of his life with Zhang Sanniu, when did this rough guy cherish things so much?

I have been married for more than ten years, and I don't know how many pairs of shoes I have made for him. When it is broken, I throw it away...and polish the shoes?He doesn't even wipe his own feet, what kind of shoes!

"Hey, when you went out, the soles of your shoes were covered with a layer of glue, so why did they become unbelievable treasures? I made a lot of pairs, and I didn't see you value them so much."

His mother-in-law muttered with a half-smile.

"Different."

Zhang Sanniu was talking while polishing his shoes.

"Although it's just coated with a layer of glue, look at them, how beautiful the glue package is, with ripples... It looks different when you put it on."

"And this rubber is amazing. As long as the upper is not wet, the sole will not enter the water. It is comfortable for the feet to wear, and it saves effort when walking... Mr. Ning said that these are the first pair of waterproof shoes in the great cause. !"

Having said that, he raised his chest slightly.

"I'm an old man, I don't care about food and clothing, but the shoes must not leak!"

"I can't lose my reputation as the No.1 rubber shoe!"

His wife was so angry that she didn't talk to him for three days.

Fortunately, Zhang Sanniu's No.1 title only lasted for three days.

On the fourth day, there was another Chao Pian Pian in Jiuling City.Sanshui Laodao wore his most elegant white Taoist robe, his beard and hair were neatly tidied up, and he rode a wooden bicycle around the city with a very proud expression.

His appearance can shock Zhang Sanniu too much.It literally caused an earthquake in the city.

Of course, what surprised everyone was not seeing the slovenly Taoist Sanshui wearing neat Taoist robes in his lifetime, but the strange four-wheeled cart under the old Taoist crotch.

It's really four wheels.In addition to the two large ring wheels at the front and rear, this car also has two small wheels on both sides of the rear wheel.Many of the people living in Jiuling City are Mo Zong's children, and they have been exposed to various organ structures since childhood. Naturally, they can see at a glance that the function of these two small wheels is to stabilize the balance of the car.

The small wheels are wooden wheels with a metal hub in the middle, and the outer layer is coated with resin to prevent wear and tear, the same material as the two large wheels on the car body.

It's just that the material is also strange. It's not metal or wood, but it looks a bit like the infusion tubes used in medical clinics.

"Is this resin?"

Liu Tong stepped forward and touched the taupe tire.

It doesn't feel soft, but it is very elastic, and it seems to be filled with other things.

"The outer layer is resin, and the inner layer is rubber cut by Ning Juzi. The inside is hollow and filled with air."

The old man looked proud, and picked Liu Tong by the way.

"Hey, be careful. This is the world's first bicycle. It's expensive. Don't touch it."

Hearing that he was number one in the world, Liu Tong suddenly felt that he was tall, and he was extra cautious when he struck.

Although this thing is a wooden structure plus a transmission structure, it may bear the key points of the old way, but I have never seen it, let alone it is crowned with the shiny golden signboard of "Ning Juzi".

Now everyone in the border town knows that Mo Zong's Juzi is the number one magical figure in the world, and he can always create all kinds of weird but extremely magical and useful things.The old man cycled around the city three times, and almost attracted all the idlers who had nothing to do at this time to the square.

Under the eyes of all the people, the old man's vanity was greatly satisfied.

With great interest, he showed the audience several times of double-wheel drift on the right rear side and riding with his hands off the handlebars, which instantly aroused the exclamation and applause of the crowd.

The old man jumped down from the car seat in a chic manner, with a fairy-like expression on his face.

"This is a bicycle, a car that can walk by itself."

"As long as you step on it, you can experience the feeling of flying through the clouds and flying like lightning, which is very enjoyable."

An old man with a white beard pushed a four-wheeled bicycle with training wheels, and he was able to stupefy the crowd, thanks to the old man's tough skin.

You must know that when this car first came out, the two rear training wheels did not exist at all.

This thing was originally a blueprint that Ning Zaozi drew in his spare time. He was surprised by the old Taoist after he saw it accidentally. come out.

Ning Fei doesn't care. Under the current traffic conditions, bicycles are actually not very useful, unlike oil extraction and sugar boiling technology, which can directly change people's lives.

It can be used in places with good road conditions in the border towns, but if it is replaced by muddy dirt roads outside the border towns, it will probably be unacceptable.

Ning Zaozi's reply to Sanshui Laodao was "Without rubber, tires cannot be made".

The veteran did not give up, and begged Nada to build one according to the blueprint. As a result, the wooden wheels could not be ridden at all, and he was bumped before taking two steps.

No matter how unwilling he was, the Sanshui old man had to admit that Ning Juzi was extremely reliable in scientific research. He said that if he can't succeed, he can't succeed, and it's useless to struggle.

After waiting for two months like this, Lao Dao finally got the green rubber dandelion, so how could he miss the opportunity to realize his dream, so he naturally started to prepare it immediately after returning home.Everything about the bike was ready-made, Ning Juzi with rubber tires came up with the blueprints, and the old man dragged the craftsman Nada together for seven days and seven nights, and finally successfully built the first bicycle in history.

The old man thought that he would reach the pinnacle of his life from now on, but he never expected that he worked so hard to overcome the difficulty of rubber tires, but fell down on the road while riding, and was crushed to death by the wheels, unable to turn over at all.

In fact, in Ning Juzi's impression, Lao Dao is a magical figure with some kung fu foundation. Not only can he read the sky and do skills, but he can also fly with a long spear, which is quite a bit like a warrior in the battlefield.

He once asked Brother Mu Ye in private, and he knew that this old man was born in a military family, and because he was obsessed with natural science, he took the "wrong path" of looking at the sky.

Although the old man talks about it all day long, the kung fu under his hands is real.Being able to make a name for himself under Feng Kai's tent, the old way doesn't just rely on counting the farming seasons, but also playing with the calendar. When necessary, there is no problem in going to the field to kill the enemy.

Such people generally have excellent balance and body control. Cycling is a dynamic balance technique, which is not difficult for the experienced.

But what I never expected was that the old man... really couldn't learn it!

It's really not, the kind that doesn't get the hang of it no matter how you teach it.

When the veteran is not riding a bicycle, he understands everything. As soon as he gets on the bicycle, his mind goes blank. He rides crookedly, and even bumps into people or objects, which can be called a murder weapon.

"Don't mess around with your hands!"

Ning Sawzi went crazy.

He finally realized the difficulty of being a driving school coach.

Even though he could stand on the ground with his feet outstretched, the old Taoist was able to ride into the ditch with his legs firmly clamped on the beam of the car.

Seeing Sanshui Taoist Chief who had lost his immortal demeanor and fell into a pig's head, Ning Zhizi, who had never surrendered to fate since crossing, knelt down.

"Let me install two training wheels for you."

He said lamely.

Lao Dao is also a man of his age. Although he looks healthy, he can't stand the repeated crashes and trees.The training wheels used by children who are just learning to ride bikes don’t look very cool, but at least they can support the old man from breaking his legs and feet, and by the way, save the precarious green plants in his yard and his mood that may explode at any time.

If this goes on like this, he might not be able to bear the irritability of attacking the old Taoist, and it will be difficult to explain to Brother Mu Ye at that time.

"A training wheel?"

The old Taoist crawled out of the ditch, his Taoist robes were covered in dust, he scratched at the buns of the loose city bird's nest, and grinned.

"what is that?"

"Just wait, it's not difficult."

Ning Fei asked Nada to touch two wooden wheels, added two brackets to the rear frame, and rolled some resin to make a wear-resistant layer.

Needless to say, with these two wooden wheels, the old Taoist got started immediately.

Not only did he fly off the bike, but he also learned the four-wheel drift technique without a teacher, and then rode happily to the city to show off.

"It's difficult."

The old man patted the car seat.

"Do you see these two wheels? They are both hollow inside. Nada and I blow into them. To tell the truth, to say it is not true, it is bumpy and transmits force in reality, and there is no support for emptiness. Only when you have time can you bear the weight of your life.”

What he said was cloudy, mysterious and mysterious, and sure enough, the crowd of onlookers were blown into awe.

Liu Tong watched from the side with hot eyes.

During this period of time, he was busy modifying the steam valve of the water wheel in the Frontier Precision Workshop. He just returned to Jiuling City today, and he consciously missed a lot of new things.

Just like Lao Dao’s car, the design couldn’t be simpler. Two axle rods and a beam are the basic structure. The chain in the middle is used as a transmission system to connect the two axles. The speed control gates are set above the front and rear wheels. The small wheels at the back seem to be Disassembled for stability.

Liu Tong admired it straight from the bottom of his heart, bluntly saying that the design of this car is extremely exquisite, which he has never seen or heard in his life.He blew a wave of rainbow farts on the old man's new car, making the old man feel comfortable physically and mentally, and called Liu Tong this kid with vision.

But Liu Tie, who had stood aside for a long time, scratched his head and asked stupidly.

"Master Dao, I see that the two rear wheels are very redundant. Will it be more flexible to ride after removing them?"

As soon as these words came out, he saw the old man's face turn green.

Liu Tie's words hit the wound in the old man's heart, although the old man is now high-spirited and fairy-like, but he will never forget the weak and helpless self in the Ning saw yard.

"Remove what!? How can you have so much time to disassemble! You have the courage to dismantle the parts specially added by Ning Juzi?! Do you think your wings are hard?!"

Liu Tie looked aggrieved by the scolding.

He didn't really question Moko's idea, he just felt that these two wheels were really useless except for support.If the ability of the cyclist is good, the consumption of a part can be saved.

Jizi said that resources are precious, and it is good to save some, isn't it?
