Whenever I want to tell everyone new knowledge, Bai Wutong is very grateful to Yang Quanzi for giving her a copy of the "Complete Book of Baiye".

The craftsmanship of casting roads is mentioned in the "Complete Book of All Trades", but it is very rough.

However, the structure of the foundation by the levator mason in the book is similar to the principle of Bai Wutong's concrete road poured with reinforced concrete.

Asphalt roads only need to be poured with asphalt before the cement is fully set.

Bai Wutong found a group of skilled craftsmen to write and draw on the blackboard. After the craftsmen understood it, they found another way to try the work.

With coal as combustion energy, the temperature rises rapidly, and it is much easier to refine steel bars.

A large number of steel bars were shipped in, and people who did not need to work gathered around, wondering what Bai Wutong was going to do.

Zhao Pengfei is very powerful and is a good hand at work.

Since he was completely rejected by Zhao Lanzhi, his heart was ashes, and he desperately devoted himself to the construction of Happy City.

Everyone opened their eyes, Zhao Pengfei was already at work, everyone closed their eyes, Zhao Pengfei was still at work, and the cows were going to be mad at him.

Bai Wutong wants to repair the road, and Zhao Pengfei is the most active one.

Others need tools to twist the rebar, and he can do it with his bare hands.

About 100 meters of concrete road, because of the large number of people, the steel foundation was laid in one day.

The next day, Bai Wutong asked everyone to lay cement.

The cement for road repair needs to be mixed with sand to make it stronger.

The sand and stone mixer Bai Wutong also made Zhao Yuan come out, but unfortunately it was not electric, but hand-cranked from behind.

Even if it is hand-cranked, the effect is actually quite good. After a steady stream of sand and gravel are mixed, the road is covered, and the road is smoothed with cement.

It is too laborious to smooth a little bit manually. There are special road machines in modern times, which can directly press the road, not only to flatten the road, but also to bake the road more firmly.

They don't have such awesome conditions, they can only be smoothed out little by little by manpower.

After the cement has been thoroughly air-dried, the road will form a gray-white flat ground, which is the same as the ground of the villa they built. It is smooth and comfortable to step on the ground with bare feet.

Bai Wutong went up and tried it, and was very satisfied. He said to the workers who participated in the construction of the road: "The road is very successful and strong. From tomorrow, we will officially start building the first road in Lingguo. As the chief technical construction workers, you guys Their names will be recorded in the annals of history.

Even repairing a road was able to write his name in the history books, and everyone cheered excitedly.

The cement road has mastered the technology, and the asphalt refining technology is still immature, so Bai Wutong took a breath and planned to eat it into a fat man.

In addition to building the road that runs through the entire southern Xinjiang to the Central Plains, they also have to deploy manpower to build the coastal road to the coal mine, the mountain road to the iron mine, the direct road to Baye City, and the road to various workshops. The traffic road in Happy City.

With the road, the means of transport naturally have to keep up.

The number of horses is still too small. The thousands of horses purchased from the Syrians and the 5,000 horses originally raised by Gu Chilie, adding up to more than 10,000 horses, cannot keep up with the speed of the crazy infrastructure.

For the first time, Bai Wutong had the plan to manufacture a bicycle tricycle.

Although bicycle tricycles can't carry much goods, it is very convenient for everyone to rush from tents to various workshops to work.

The modern country of Kawafu is also known as the bicycle kingdom because of its flat terrain.

The bicycle is also an iconic product of the early entry into the industrial age.

Owning a bicycle is definitely a symbol of the upper class.

Bai Wutong figured it out, if there was a bicycle, it would have taken more than a month to enter the southern border. If there was no delay on the road, half a month would be enough.

To ride a thousand miles, a bicycle must be built.

When bicycles and tricycles are available, power plants are built, and cars are built, the production conditions at that time should be easy.

Bai Wutong remembered that in the history class, the first car in China was built from scratch, under what basic conditions, it took three months to build.

After three years of hard work, Huaguo has a complete automobile production line.

At that time, there was still no technology and no equipment.

Now, there are a lot of data drawings in the Baiwutong space, and if you want to develop a car, it must be just around the corner.

But it's not too fast, she's afraid of being treated as a demon.

Bai Wutong feels that she will open a small stove for Zhao Yuan and give him a little inspiration to design a car, so that he now has the idea of leading people to start a car, and with her help in the future, he will be able to build a car logically!

As soon as it was said, Bai Wutong turned around the carriage under the sun, and everyone immediately gathered around and asked Bai Wutong what was the problem.

Bai Wutong smiled and said, "I was thinking that the carriage has four reels. If we ride on those two reels, will we be able to run."

As soon as these words came out, many carpenters and blacksmiths and craftsmen who had gained a lot of knowledge from Bai Wutong fell into contemplation.

Zhao Yuan and Zhao Sheng have been with Bai Wutong for the longest time, and have also helped Xiu Xiu make various small cars, moving Trojan horses, sleds flying on the ice, and various operating machinery.

Bai Wutong proposed a two-wheeled car, thinking of the rapidly rotating handle of the meat grinder. In an instant, inspiration collided in his mind, sparks were everywhere, and Zhao Yuan shouted: "I thought of it!"

Bai Wutong was stunned, so fast!

Zhao Yuan thought about it, and many blacksmiths and carpenters were not convinced. After racking their brains, they also came up with a car that could be ridden on two wheels.

They all said to Bai Wutong: "Princess, we also thought of it!"

Bai Wutong originally wanted to talk about the structure of bicycles, but found that everyone was more positive than the other, so he didn't restrain everyone's ideas, and said with a smile: "Well, if anyone can make two wheels that satisfy me the most within a month. A car, a reward of 100 taels of gold, and a villa of 300 square meters."

At any time, scientific researchers deserve the best, and Bai Wutong suddenly came up with the idea of establishing an invention award.

One hundred taels of gold! ! !

A villa of 300 square meters! ! !

sky! ! !

The rewards are too generous!

Everyone's eyes went straight~www.mtlnovel.com~ Even many people who were not craftsmen were moved.

Not just let two wheels run, they can do it!

If you get Bai Wutong's approval, you won't have to fight for a few lifetimes.

Everyone was so excited that they spread the word from ten to one hundred, and many people secretly made inventions when they were not working.

The men started their own work, and within a month, they quickly fiddled with a lot of two-wheelers.

But they are two-wheeled vehicles, which is really a bit strange.

Some of the wheels are as wide as a tank, some have a big basket directly on the two wheels, some are like toothpicks connected, there is no safety at all...

With so many people present, only Zhao Yuan came up with a bicycle that had similar thinking to Bai Wutong's.
