Heavenly Dao Formula

Of course, it’s not a question of whether it’s called a car, because compared to the earliest steam-driven bicycles in history, there is no place on it that can be linked to steam.

The object is apparently powered by astronomical instruments.

It stands to reason that Xuanwu can be manufactured, and it should be easier to build a car. The reason why Xia Fan didn't let the Machine Building Bureau produce it is because the former has a greater effect on war, and the limited production capacity must be used wisely. According to the original plan, he wanted to wait for the war to come to an end before handing over the concept drawings to Mo Yun for design. Unexpectedly, the other party went faster than his plan, and had already produced the prototype one step ahead of schedule.

This machine has a total of three pairs of wheels. The guide wheels are arranged in the front, with an inner diameter of about an arm's length, and the rear wheels are a circle larger, and are symmetrically distributed on two axes, which is equivalent to a standard four-wheeled carriage. Interestingly, Mo Yun designed the guide wheel as a handle control, which is just like a bicycle. This design has many advantages, firstly, the steering sense is very intuitive, and it will not be indistinguishable from left to right like a steering wheel; secondly, the two handles are the air transmission channels, which can simultaneously stimulate the astronomical instrument when grasping, combining drive and control together.

But the disadvantages of doing so are also obvious.

That is, people with weak strength cannot drive this car.

Of course, these are trivial matters.

The most attractive place to Xia Fan's attention is probably the wheels of the vehicle.

The biggest difference between it and those early products in history is that the four rear wheels are thick and wide. Its whole body is made of iron, with a horizontal width of more than one palm, and the shape of the wide tire is very domineering. At the beginning of the invention of the car, the four wheels were almost the same as those used by bicycles. Basically, two bicycles were put together, and an engine was plugged in the middle.

Such a thick rim can bring strong stability and load capacity, but the corresponding price is greater resistance and enhanced vibration.

Mo Yun's countermeasure is to catch shellac.

"The light test was successful?"

"Well, thanks to your guidance." She nodded generously, "In the past few months, I have offered a lot of rewards to the caravans to and from the mountain for fluorite and rare crystal minerals, hoping to find suitable ones that can be inspired by the immortal fire. Medicine introduction. At the same time, sort out the ripples in the technique, and redraw the talisman according to the spectral concept you mentioned. Finally, among thousands of stones, nine types can be used as medicine introduction."

"Wait... Did you do the experiment yourself?" Xia Fan asked in surprise.

"Yes, except for me, no one can use those talismans." Mo Yun laughed, "But don't worry, I have set up a special warehouse in the outskirts of Jinxia to store and test them, and pay attention to personal safety during the test. There is basically no risk of poisoning."

But the invisible light emitted by these stones cannot be prevented by gloves and masks.

Fortunately for him, natural minerals are of low purity, and their inherent radioactivity is much weaker than artificial elements, so short-term exposure will not cause any irreparable damage.

"I will make a special protective suit for you, please wear it next time before testing." Xia Fan said word by word while grabbing her shoulder.

Facing such a serious Xia Fan, Mo Yun's eyes flickered for a moment, and then he reluctantly agreed after a while, "Okay, I will do as I am."

Xia Fan let go of his hand in satisfaction, "And then? How do you make these tires?"

"Tire? It's another weird word." Mo Yun shrugged, "It's not difficult to say, I will make the wheel blank first, make sure it is as round as possible, and then coat it with a layer of tin. In this way , its surface is as bright and clear as a mirror just out of the oven."

Jinxiacheng's tin plating technology has been greatly honed in the can industry, and it is not difficult to cover the wheel hub with a layer of tin film.

Xia Fan also immediately guessed the opponent's intention.

She wanted to use specular reflections to increase the intensity of light in the shellac.

Sure enough, Mo Yun continued, "After tinning, put the wheel embryo into the template, pour shellac from the surroundings, use natural light to solidify the surface, and finally remove the template, use the talisman of Jiuyouhuo to cast spells, and last After three to four hours, the colloid will completely adhere to the wheel embryo."

Xia Fan couldn't help but want to applaud her.

This process of Mo Yun has made the best use of the technology in her hands - the hardness of shellac solidification is related to the intensity of light, so she first hardens the surface layer, and then uses the more penetrating Jiuyou fire to irradiate layer by layer, making the carcass Hard and soft inside, in a sense, it is similar to pneumatic tires, and there is no need to worry about sharp objects piercing the tread.

It is with this layer of buffer that the wheels of the mechanism beast can be made big and wide.

"I guess it doesn't just use the Celestial Motion Meter?" When Xia Fan circled the car, he also noticed that its wheels were not rigidly connected to the carriage, but were separated by sleeves in the middle.

"That's right, as expected of you." Mo Yun admitted, "I also installed two sets of Xunfeng seals under the frame, which can inject a large amount of gas into the sleeve to further reduce the vibration caused by ground bumps."

Xun Fengyin...Xia Fan remembered that it was one of the magic weapon blueprints that he had found from the Record Department of the Privy Council.

"How much cargo can it carry?"

"It can reach more than 10,000 catties. No matter how heavy it is, the ground won't be able to bear it." There was a hint of pride in Mo Yun's tone.

She is indeed something to be proud of.

The weight of 10,000 catties has far exceeded the carrying capacity of a horse-drawn carriage. Although there is still a considerable gap compared with the overlord dump truck on the road, it is definitely an astonishing statistic in this year. To put it simply, the goods carried by this cart at one time are fully equivalent to the amount of goods carried by a caravan with ten carriages.

The stone pavement of Jinxia City can still bear this kind of weight, but the official roads between the cities can no longer keep up with the progress of the times.

"Its speed is comparable to that of a horse-drawn carriage, and it doesn't need to stop at a post station to save horsepower. It can drive during the day and night." Mo Yun continued, "If this mechanism beast is used to transport Xuanwu, it can take the Xuanwu army from Jinxia to Jinxia in one day. Transfer to the border town of Shenzhou. After that, Xuanwu will fight on foot, and the attrition rate can be reduced by about 60%."

Xia Fan shook his head, "If it is only used to transport Xuanwu, it would be a bit wronged. How about it... You try to build a production line and see how many vehicles you can produce in a month. If you don't encounter any technical problems, the next A special factory will be opened every month to produce it, and all expenses will be paid by the finance department.”

Although the Fang family's logistics business is getting bigger and bigger, it cannot be separated from the inland waterway after all.

The invention of Moyun just filled this gap.

"Is it necessary to build so many?" She was a little surprised, "It has higher requirements on the road surface, and it is not as convenient as a horse-drawn carriage..."

"However, the road can be repaired," Xia Fan raised the corner of his mouth. "Since you built it, you should imagine that one day the carriage will be completely replaced by it. By the way, does this mechanism beast have a name?"

Mo Yun shook his head, "It's better for you to come and get it... This is also one of the reasons why I asked you to come here."

Xia Fan didn't back down either, he thought for a while and said, "In that case, let's call it "liberation". "
