Chapter 683 Liberation

Of course, it’s hard to say whether it’s called a car or not, because compared to the earliest steam-driven bicycles in history, there’s nothing about it that can be related to a car.

This thing is obviously driven by a celestial device.

It stands to reason that Xuanwu can be manufactured, but it should be easier to build a car. The reason why Xia Fan did not let the Machine Manufacturing Bureau produce it is because the former has a greater impact on the war, and the limited production capacity must be used on the cutting edge. According to the original plan, he wanted to wait until the war was over before handing the concept drawings to Mo Yun for design. Unexpectedly, the other party went faster than he planned and built 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. The wheels at the back are one circle larger and are symmetrically distributed on two axes, which is equivalent to a standard four-wheel carriage. Interestingly, Moyun designed the guide wheel as a grip-type control, which makes it easy to operate like a bicycle. There are many benefits to this design. Firstly, the steering feels very intuitive and does not distinguish between left and right like a steering wheel. Secondly, the two handles are the air delivery channels. While grasping, it can activate the celestial instrument and combine driving and control. together.

But the shortcomings of this are also obvious.

That means people with weak strength cannot drive this car.

Of course, these are minor issues.

The thing that caught Xia Fan's attention the most was 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. It is made entirely of iron, with a width of more than a hand, and a wide-tire shape that looks very domineering. When the car was invented, the four wheels were almost the same as those used on bicycles. They were basically two bicycles put together with an engine stuck in the middle.

Such a thick rim can bring extremely strong stability and load-carrying capacity, but the corresponding price is increased resistance and increased vibration.

Mo Yun's countermeasure is shellac.

"Did the light test succeed?"

"Well, thanks to your guidance." She nodded generously, "In the past few months, I have offered huge rewards to caravans for fluorite and rare crystal minerals in the mountains, hoping to find something suitable for stimulating the Nine Nether Fires of Immortal Art. Medicine guide. At the same time, I sorted out the ripples in the technique and redrawed the talisman according to the spectrum concept you mentioned. Finally, I found nine types of stones that can be used as medicine guide. "

"Wait... did you do the experiment yourself?" Xia Fan said in surprise.

"Yes, no one can use those talismans except me." Mo Yun laughed, "But don't worry, I have established a special warehouse in the suburbs of Jinxia to store and inspect them, and I have paid attention to personal safety protection during the experiment. There is basically no risk of poisoning.”

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

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

"I will make you a special protective suit. Please wear it next time before testing." Xia Fan grabbed her shoulders and said word by word.

Facing Xia Fan who was so serious, Mo Yun's eyes flickered for a moment, and after a moment he reluctantly agreed, "Okay, I'll just do it."

Xia Fan let go with satisfaction, "Then what? How do you make these tires?"

"Tire? Another weird word." Mo Yun shrugged, "It's not difficult to say. I first make the wheel base, 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 freshly baked mirror.”

Jinxiacheng's tin plating technology has been honed in the can industry for a long time. It is not difficult to cover the wheel hub with a layer of tin film.

Xia Fan also immediately guessed the other party's intention.

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

Sure enough, Mo Yun continued, "After tin plating, put the wheel embryo into the template, pour shellac from around it, use natural light to solidify the surface, finally remove the template, use the talisman of Jiuyouhuo to cast spells, and continue In three to four hours, the colloid will completely adhere to the wheel base.”

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

Mo Yun's process makes the best use of her skills - 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 Nine Nether Fire to irradiate it layer by layer, making the outside of the body Hard on the inside and soft on the inside, in a sense it is similar to pneumatic tires, but there is no need to worry about sharp objects puncturing the tread.

It is precisely because of this layer of buffering that the wheels of the machine beast can be made larger and wider.

"I guess it doesn't just use a celestial device, right?" As Xia Fan circled the car, he also noticed that its wheels were not rigidly connected to the car, but were separated by sleeves in the middle.

"Yes, 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 sleeves to further reduce the vibration caused by bumps on the ground."

Xun Feng Seal... Xia Fan remembered that it was one of the drawings of the magical artifact that he had collected from the Privy Council's Records Department.

"How much cargo can it carry?"

"It can reach more than 10,000 kilograms. If it's any heavier, 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 kilograms far exceeds the carrying capacity of a horse-drawn carriage. Although it is still far behind the dominant dump truck on the road, it is definitely shocking data in this year. To put it simply, the cargo this car can carry at one time is enough to carry the cargo of a caravan with ten carriages.

Jinxia City's stone pavement can still withstand such a weight, but the official roads between 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 the inn to save horsepower. It can travel day and night." Mo Yun continued, "If this machine beast is used to transport Xuanwu, the Xuanwu army can be transported from Jinxia in one day. By moving to the border towns of Shenzhou and then fighting on foot from Xuanwu, the attrition rate can be reduced by about 60%."

Xia Fan shook his head, "If you only let it transport Xuanwu, it would be a bit wronged. Let's do it... you try to build a production line and see how many vehicles can be produced in a month. If you don't encounter any technical problems, let's go A factory will be dedicated to produce it every month, and all costs will be paid by the Finance Department.”

Although the Fang family's logistics industry is getting bigger and bigger, it is ultimately inseparable from inland waterways.

Mo Yun's invention just fills this gap.

"Is it necessary to build so many?" She said slightly surprised, "It has higher requirements on the road surface. In fact, it is not as convenient to use as a 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 machine beast have a name?"

Mo Yun shook his head, "It's better that you come and get it... This is also the reason why I asked you to come."

Xia Fan didn't give in. He thought for a while and said, "In that case, let's call it 'liberation'. "
