Of course, it is still a bit different whether it is called a car or not, because compared to the earliest steam-driven self-driving vehicles in history, there is no place on it that can be related to the steam.

This object is obviously driven by an astrometer.

Logically speaking, even Xuanwu can be made, so it should be easier to build a car. The reason why Xia Fan did not allow the machine to produce is because the former has a greater effect on the war and the limited production capacity must be used on the blade. 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 walked faster than his plan and built the prototype one step ahead of time.

There are three pairs of wheels in this machine. The guide wheel is arranged in the front with an inner diameter of about one arm. The wheels at the rear should be larger and distributed symmetrically in two axes, which is equivalent to a standard four-wheeled car. Interestingly, Mo Yun designed the guide wheels to be grip-type control, which is like a bicycle when operating. There are many benefits of this design. First of all, the steering feel is very intuitive and will not be separated from left and right like the steering wheel; secondly, the two grips are the air conveying channels, which can take into account the excitation meter while grasping, combining drive and control.

But the disadvantages of doing this are also obvious.

That means that people with low strength cannot drive this car.

Of course, these are all trivial issues.

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

The biggest difference between it and the early products in history is that the four wheels at the rear are thick and wide. Its whole body is made of iron, with a horizontal width of more than one palm, and the wide tire looks very domineering. When the car was invented, the four wheels were almost not much different from those used by bicycles. Basically, two bicycles were put together and an engine was stuffed into the middle.

Such thick rims can bring extremely strong stability and load capacity, but the corresponding cost is that the resistance becomes larger and the vibration is enhanced.

Mo Yun’s countermeasure is to catch insect glue.

"The light test was successful?"

"Well, thanks to your guidance." She nodded generously, "In the past few months, I have paid a reward of mountain fluorites and rare crystal minerals to the caravan, hoping to find a medicine guide suitable for the excitation of the Nine Nether Fire of the Immortal Art. At the same time, I sorted out the ripples in the magic and repainted the talismans according to the spectral concept you mentioned. Finally, among the thousands of stones, nine categories that can be used as medicine guides were found."

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

"Yes, no one can use those talismans except me." Mo Yun laughed, "But don't worry, I have set up a special warehouse outside Jinxia to store and inspect them, and I pay attention to personal safety protection during the test, so I will basically not encounter the risk of poisoning."

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

Fortunately, natural minerals have low purity and are much weaker in their own radioactivity than artificial elements. Short-term contact will not cause any irreversible damage.

"I will make you a set of special protective clothing. Please put it on next time before testing." Xia Fan said word by the way, grabbing her shoulder.

Facing such a serious Xia Fan, Mo Yun's eyes flashed for a moment, and after a moment, he reluctantly agreed, "Okay, I'll do it."

Xia Fan let go of his hand with satisfaction, "Then what? How did you make these tires?"

"Tyre? Another weird word." Mo Yun shrugged, "It's not difficult to say. I first make the wheel embryo to ensure it is as round as possible, and then coat its surface with a layer of tin. In this way, its surface is as bright and clear as the mirror just released."

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

Xia Fan immediately guessed the other party's intention.

She wanted to rely on mirror reflection to increase the intensity of light exposure in insecticide.

Sure enough, Mo Yun continued, "After tin plating, put the wheel embryo into the template, pour shellac into the surrounding area, use natural light to solidify the surface, and finally remove the template, use the talisman of Jiuyouhuo to perform magic. For three to four hours, the colloid will be completely attached to the wheel embryo."

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

Mo Yun's process simply utilizes the technology in his hand to the extreme iron gel hardness and light intensity. Therefore, she first hardens the surface layer, and then uses the more penetrating Jiuyou Fire to irradiate layer by layer, making the carcass hard outside and soft inside. In a sense, it is similar to the pneumatic tire, and there is no need to worry about sharp objects piercing the tread.

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

"I guess it not only uses an astronaut, right?" When Xia Fan was spinning around the car, he also noticed that its wheels were not rigidly connected to the car, but were separated by a sleeve in the middle.

"Yes, it's you." Mo Yun admitted, "I also set up two sets of Xunfeng Seals under the frame, which can inject a lot of gas into the sleeve and further reduce the tremor caused by the bumps on the ground."

Xunfeng Seal... Xia Fan remembered that it was one of the magical instrument drawings that were plundered from the Record Department of the Privy Council.

“How much cargo can it carry?”

"It can reach more than 10,000 kilograms. If it is heavy, the ground will not be able to withstand it." Mo Yun's tone was vaguely proud.

She is indeed proud of her.

The weight of ten thousand pounds is far exceeding the carrying capacity of a carriage. Although there is still a considerable gap compared to the road overlord's mud truck, this idea is definitely a shocking data. Simply put, the carriage carried at one time is equivalent to the carriage carrying ten carriages.

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

"Its speed is equivalent to a carriage, and it does not have to stop at the post station to rest to save horsepower, and it can drive day and night." Mo Yun continued to introduce, "If this machine beast is used to transport Xuanwu, the Xuanwu army can be mobilized from Jinxia to the border town of Shenzhou in one day. Then Xuanwu will fight on foot, and the loss rate can be reduced by about 60%.

Xia Fan shook his head, "If you only let it transport Xuanwu, it would be a bit aggrieved. This way... 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 difficulties, open a factory to produce it next month, and all the 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 the inland waterway.

And Mo Yun's invention just filled this gap.

"Is it necessary to build so many?" she said a little surprised, "It has high requirements for road surfaces, and it is actually not as convenient as a carriage..."

"However, the road can be repaired," Xia Fan raised his lips, "Since you have made 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, "You should come and get it... This is also one of my purposes."
