When he first saw the design drawings of the camel cart in the Taoist chapter, Lei Changye's first thought was the wooden ox and flowing horse that Zhuge Liang had invented. However, his memory of the wooden ox and flowing horse is still in the miraculous description of the Romance of the Three Kingdoms. Now that there is no Three Kingdoms era in this era, Zhuge Liang's wooden oxen and flowing horses are not passed down to the world.

However, after careful reading of Mozi's Five Elements, it was discovered that this set of machinery was actually improved from the method of wooden chariots and horses made by Lu Ban for his old mother.

It is rumored that Luban's wooden carriage and horse "have the mechanism, and it will not be returned", which is very in line with Lei Changye's expectations for desert crossing tools. In addition to the original device of the wooden cart and horse, the design of this camel cart is also designed with the unique design of camel hooves to cross the surface of quicksand.

The body of the Luban wooden carriage horse was changed to the front half of the camel, and the wheels on the carriage were all removed, replaced by wooden camel hooves and camel legs, and the shape of the whole camel carriage looked like a long camel with 24 legs, an extended version of the "desert boat".

The camel's body structure is particularly suitable for carrying people across the desert. The camel cart has strengthened the physical function of the camel and increased the cargo capacity a lot. If the core circle drive device that drives the 24 legs of the camel cart forward and turn can be developed, each camel cart can carry a weight of 100 stones, which is equivalent to the carrying capacity of six or seven camels, and the transportation convenience brought by this is the dream of all merchants.

Lei Changye spent the whole night studying the core of the circle on the camel cart. This is a composite circle of several odd arrays coupled together. The original record in the Five Elements of Mozi is relatively vague, and Lei Changye mainly reads the annotations of the patriarch Lu Yan.

Patriarch Lu Yan obviously attached great importance to the design of this camel cart. He restored about seventy percent of the formation structure. However, because the core circle was too vague, Lu Yan also had pessimistic thoughts about the role of the camel cart because of the fall of the Western Regions, and finally did not continue to study.

However, the seventy-percent formation structure restored by Lu Yan was of great help to Lei Changye. According to the brand-new formation he saw on the hoist, he corroborated each other with the seventy-percent formation, and made a comprehensive analysis of the formation structure in the compound formation little by little.

The core of the formation is driven by the Tianxing Nine Palace Array. The Tianxing Nine Palace Array is a kind of Taoist Array that relies on a special magic core structure to absorb the essence of heaven and earth to form a primordial mana.

This is a special formation that belongs to the treasure alchemists of various factions to make magic weapon spiritual materials. In the Heavenly Machine Hall of each faction, there is this layout of the Heavenly Nine Palace Array. Relying on the large array to collect the spiritual power of heaven and earth, it is gathered on the treasure material, and after a period of time, the spiritual power of the treasure material is changed, and it is transformed into a spiritual material, which becomes the material for making magic weapons.

However, the absorption speed of the Tianxing Nine Palace Array was very slow, and the speed at which the treasure material was transformed into a spiritual material was also very slow. Therefore, the camel cart array was outside the Tianxing Nine Palaces Array, and a total of nine Spirit Transmission Arrays were added to the circle, which secretly matched the layout of the Nine Palaces.

The Soul Transmission Circle was born from the Spirit Transmission Talisman. The spirit talisman is a special talisman that absorbs spiritual thoughts from the caster to activate the magic circle, and has the effect of quickly transmitting mana. The Soul Transmission Circle maximizes this effect, creating a miraculous effect that accelerates the absorption of mana. The coupling of the Nine Spiritual Transmission Arrays with the Tianxing Nine Palace Arrays can quickly absorb the spiritual power of heaven and earth to the greatest extent and drive the operation of the magic array.

Once the spiritual power of heaven and earth is absorbed, the spiritual power is immediately converted into mana through the magic circle and acts on the camel cart, forming a power for steering and driving.

This was originally a very perfect and advanced magic core design, and it was also the first time that Lei Changye came into contact with a device that could directly absorb spiritual power from heaven and earth and transform it into mana.

It's a pity that the Spirit Transmission Array has become the biggest difficulty faced by Lu Yan and the creators of Mozi's Five Elements. Because this kind of spirit transmission circle itself also needs to be driven by mana to be able to play a role. Of course, Lu Yan himself could activate the Spirit Transmission Array, but only he could. Where do other talismans have such abundant mana?

Moreover, Lei Changye calculated a little, and found that the amount of heaven and earth spiritual power absorbed by consuming so much mana was probably not enough to be consumed on the Ninefold Spirit Transmission Array.

He also thought about using the Heavenly Thunder Fu to activate the Ninefold Spirit Transmission Array, so that it could operate normally, absorb the spiritual power of heaven and earth, and run the camel cart. However, this requires nine Heavenly Thunder Talismans, and according to the average price of the Black Market Heavenly Thunder Talismans, the loss is nine thousand yuan. He felt that consuming such a large amount of heavenly thunder energy, why should he absorb any heaven and earth spiritual power, and it was enough to directly use it to make an electric camel cart.

Moreover, Lei Changye was very interested in the coupling of the Tianxing Nine Palace Array and the Spirit Transmission Array. This kind of coupling can speed up the efficiency of absorbing the spiritual power of heaven and earth, if the structure of the formation can be improved, the composite array with reduced loss can be found, and the magic circle can be activated in a low-cost way, isn't this a perpetual motion machine?

Lei Changye first added the Tianshu Exorcism Array that he was most familiar with on the basis of the Nine Great Spirit Transmission Arrays. The Tianshu Exorcism Array is a formation to drive the Yin General, but when he made the Imperial Butler, he once improved the Exorcism Talisman and added five jade talismans to strengthen it, as a power source to assist his divine sense to drive the Imperial Butler.

He pushed the improved Exorcism Talisman back to the Tianshu Exorcism Array, and used the new circle drive structure he saw when the ship gourd transformed the Flying Fish Lady Ship to change the Tianshu Exorcism Array Demon into a power source that could activate and drive nine Soul Transmission Circles at the same time.

Because the exorcism talisman needed to drive the body of the royal housekeeper to run continuously for a long time, Lei Changye had to consume five jade talismans to maintain its effectiveness.

However, in the design of the camel cart, the Tianshu Spirit Driving Array can be combined with the Ninefold Spirit Transmission Array to drive the Tianxing Nine Palace Array to absorb the spiritual power of heaven and earth. What really maintains the operation of the camel cart is no longer the Tianshu Exorcism Array, but the Tianxing Nine Palace Array. The Tianshu Exorcism Array only needs to drive the magic circle, so it doesn't need a jade talisman to maintain it.

After that, he coupled the Tianshu Exorcism Array with the Nine Great Spirit Transmission Arrays, making the Tianshu Exorcism Array the main hub of the Great Array. With just one Heavenly Thunder Talisman, you can activate the magic core composed of the entire composite array.

In this way, he has reduced the start-up cost from the original 9,000 to the current 1,000. Moreover, as long as the Heavenly Pivot Spirit Transmission Array has been in operation, under its drive, the Nine Great Spirit Transmission Arrays will also maintain operation.

This Tianshu Exorcism Array has become another key core magic circle of the camel cart, and this formation does not need to consume a single jade talisman, and all the losses come from the Heavenly Thunder Talisman.

Lei Changye has no quantitative standard, and he can't calculate whether the consumption of the Heavenly Thunder Fu and the absorption of heaven and earth spiritual power are equal. He hopes to experiment to see how long a camel cart can travel with a Heavenly Thunder Talisman activated. As long as the camel cart can keep running and get out of the desert, then the thunder charm will be worth the price on this day.

At this time, the price of a camel in the Tang Dynasty was about 25 guan a piece, which was slightly more expensive than the price of a donkey. However, because the trade routes in the Western Regions were cut off, camels could not be sold at a high price. In the heyday of the trade route, the high-quality breed camel was about 30 to 40 guan per camel, and with the cost of grain, grass, water and domestication, the loss of a camel was about 80 guan.

But a camel cart has a lot of space, and if it can seat more than 20 traders, there will be more than 20 camels left, which is 1,600 yuan. These vendors pooled together their money to buy a thousand pieces of Heavenly Thunder Talismans, and they could cross the desert safely without damage. As for their goods, they won't take up space, because Lei Changye still has alliance treasure bags that can be rented to them for sharing.

They can even rent more alliance treasure bags to transport more goods to the outside of the plug and make a lot of money. Lei Changye can also sell a little more Tianlei Fu to speed up the return of funds.

This beautiful prospect, Lei Changye can't wait to see. However, the premise of everything is how long this camel cart can travel with a heavenly thunder talisman.

Wang Mang is also very interested in the design of the camel cart. Each of Lei Changye's magic weapons is very interesting, and once it is designed, it will inevitably cause a sensational effect. At the beginning, the completion of the magic weapon of twisting and dredging made him really out of the limelight for a period of time. When the silt at the mouth of the Yangtze River was cleaned up, even a wharf bearer in Guazhou Port recognized Wang Mang, and greeted him from afar, as if he had seen a relative.

This made him excited for a long time, and in comparison, the ten five-rank witch cores that Lei Changye promised him were not worth mentioning.

This time, Lei Changye designed the camel cart, and also made an agreement with him, once the camel cart was completed, a firm will be established by the Wumeng Craftsman Manufacturing Division - Wumeng Camel Company, specializing in camel cart leasing business. And Wang Mang is also the chief shopkeeper and chief craftsman of the camel shop.

In the future, the camel line will become the main business group for the development of the Western Regions by virtue of the camel cart, and Wang Mang will be the savior of the Western Regions at the level of the figure, holding the right to travel in the country.

The hidden craftsman attribute in Wang Mang's body completely broke out, and he lived in the craftsman bureau of Jinchangfang in Wumeng for seven or eight consecutive days, and a group of senior brothers of Shushan Baozong rushed to work day and night, and finally on the ninth day, all the parts of the camel cart were designed and produced.

After Lei Changye's inspection, he praised it and assembled it on the spot in the craftsman bureau. The structure of the wooden carriage designed by Lu Ban itself is quite exquisite, and Lei Changye has improved it on this basis, designing the parts for installing the Tianshu Exorcism Array Array, and at the same time it has to be connected with the nine Spirit Transmission Arrays, so the internal structure is further complicated.

It took him and all the craftsmen of the Craftsman Bureau ten hours to assemble a camel cart. By the time the assembly was completed and all the circles were carved, it was already the early morning of the next day.

After Lei Changye finished assembling, he immediately invited Wang Mang and all the main disciples of the Craftsman Bureau who participated in the assembly to get into the car together, including the Five Lucky Stars of Baozong who had come to Chang'an thousands of miles to defect to Wang Mang.

All of them are disciples of Shushan, and many of them have been following Wang Mang and Lei Changye since the construction of flush toilets in Shanjin Town, and they are extremely interested in building new machinery. This time, a car that is said to be able to carry people on a walking basis has been built, and they must see with their own eyes if it can be done, whether it is fun or not.
