When the world outside the three mountain buns turned green, the wheat ears began to turn yellow on a piece of land that was reclaimed before the New Year outside the wall of the courtyard.

It’s just that the wheat ears are yellowed, and the thick stems and plump leaves of the wheat are still green and greasy.

After a few months, under the cover of the Four Symbols and Five Elements Array, Taihe Villa seemed to be isolated from the world and became completely different.

As the formation is operated, the five elements primordial qi scattered between heaven and earth are included in the area covered by the formation. The abundant five elements primordial qi nourishes it gradually becomes a blessed place. The climate is reversed, and the four seasons are always like spring. Vegetation grows very rapidly under the nourishment of the primordial qi, and the ripening period of fruits and grains is greatly shortened, and it is against the season.

Within the walls of Taihe Villa, the pears, peaches, plums, oranges, and dates in the five courtyards were lush and green, exuding a faint fruity fragrance. In just a few months, the five fruit forests seemed to have grown here, and there was no trace of transplanting.

This villa finally looks less simple and full of vitality.

Zhao Yu was excited to drive out of the earthen yard with a huge machine. The four girls holding bamboo poles in front of the yard looked at it, screaming and fleeing away.

"Take dates again, four little greedy cats!"

Xiaochun stretched out her little head from the corner: "Sir, what is this?!"

Zhao Yu laughed: "I've been busy for half a month, and I've been in the machine car."

Zhao Yu's machine car looks similar to the modern chariot in space and time two thousand years later. It is one zhang tall, one zhang long, and one zhang wide. It is a mixed structure of stainless steel and fir. It is also a track-type.

Among the bamboo slips left by Cai Yong, there are several volumes of bamboo slips from the Mohist family, which mention the concepts of machine cars and machine birds. Zhao Yu had a sudden idea and spent more than half a month to make such a machine.

Zhao Yu's motor vehicle is a collection of modern space-time concepts and Mohist concepts two thousand years later, but the core thing belongs to the immortal way.

Because the car is not burned with gasoline or diesel, the speed of the car cannot be increased. In fact, the car used by the Mohist school uses pure mechanical energy. For example, it is like a mechanical watch. After it is built, it is winded first and then you can walk for a distance. But it is too big, the speed is not fast, and the journey is not far.

Zhao Yu thought about using the Yuan Qi of Heaven and Earth as kinetic energy, and the power core of this mechanism is actually the five Yuan Talismans.

That's why it's so big.

But unfortunately, only Zhao Yu can control this mechanical car for the time being. Only with mana can we activate the Five Elements Yuan Talisman to provide kinetic energy for the mechanical car.

Zhao Yu planned to try the performance of the machine car first, and then see if it can be modified, or transformed into a way that does not require the Five Elements Yuan Talisman and does not require mana to move, so that its speed can reach the requirements and the running distance can reach a certain level.

"Mobile car?!"

The four girls stretched out their heads from the corner of the wall one by one: "It's weird."

Zhao Yu waved: "Everyone is up, let's try the performance of the machine car."

Zhao Yu stood up from the top cover, opened the top cover, and jumped down. Then, with the extremely rhythmic creaking, the back of the machine car slowly opened, revealing the open space inside.

When the four girls saw it, they cheered. The little fish stuffed dates into their mouths, jumping around and entering the machine car.

There are simple iron frames on both sides of the interior of the machine car, which is considered as a form of a wide and high space. The eight-foot man stood up and did not feel cramped. There is a driving seat in front and a steering wheel, and Zhao Yu was sitting. The girls came in, touched here, and looked there, and were very curious.

"Stop making trouble, sit down."

Zhao Yu said: "I've driven."

The fourth girl quickly sat down properly, looking at Zhao Yu in front of her with a few pairs of eyes dripping. She felt a little shocked. Before she could react, her body could not stabilize her from the iron frame to the back of the carriage, and she screamed in fear.

Zhao Yu looked back and quickly disconnected the supply of Yuanqi. The car stopped. The four girls, who were about to stabilize, rushed forward again, and now they fell into a ball.

Zhao Yu laughed.

"Bad sir!"

The girls jumped up and pouted, feeling particularly unhappy.

Zhao Yu laughed and shook his head: "You guys don't practice hard, your strength is normal, and you can't control the balance. Now you're fine."

When the car moves, the body loses balance under the influence of external force. If you can control the strength, you can react instantly and balance it with the flow. But a few girls are very good at playing, and no matter how good the exercises are, it will be useless if they don’t practice them well.

In addition, Zhao Yu also discovered his mistake and ignored the things like seat belts. In addition, the speed was too fast just now and the instantaneous inertia was too great.

"Sit down."

Zhao Yu pretended not to see the pouting mouths of the girls. The car started again. Under the meticulous control of magic power, strands of Yuanqi flowed out of the Five Elements Yuan Talisman, and the car slowly accelerated, and now it was much more stable.

Zhao Yu thought that he should design something similar to the 'throttle'.

The huge machine car drove out of the yard, and the steel tracks crossed the gate of the other yard, crushed the threshold of the gate to pieces, and came to the bluestone avenue outside, and crushed the stone slabs.

So the cheers of the girls echoed in the blessed area of ​​the other courtyards. Later, even Guan Hai's guards came up one by one to try them out. Zhao Yu drove the machine car and went between the three mountain bags to test various performances.

The birth of the machine car added a bit of fun to the other courtyard.

After this first test, the performance of the machine vehicle was demonstrated one by one. The speed of 100 meters is between four and five seconds, and the speed is extremely rapid. If the Yuan Qi supply is released, the maximum speed can be reached in one second. Moreover, because it is a crawler type, it is not afraid of ruggedness. The whole terrain will not be due to insufficient sealing performance, and if it is in the water, it will leak.

The machine car has a large space, fast speed, sufficient horsepower, and is not afraid of ruggedness. It is used for transportation, or even military purposes. It is most appropriate.

However, it is not easy to remove traces of immortality in it, without using Yuan Talisman and not involving the way of talismans. It is not easy to produce energy for ordinary people. Unless it is completely manufactured according to the technology of modern vehicles two thousand years later, burning oil and gas, only mechanical energy is far from reaching the effect of urging Yuan Talisman.

But according to the technology after 2,000, it is not just steel, not just structure, but also a huge industrial system. I feel annoyed when I think about it. Zhao Yu simply doesn't want to just treat this machine car as out of print and just use it in another courtyard.

However, what should be modified still needs to be modified, such as transforming it into a power primordial that can be activated without mana traction. Otherwise, only Zhao Yu can drive it in the other courtyard, and it will be useless.

A few days later, the machine car was finally renovated. Talismans were used in more places, but mana was no longer needed to be activated. The "throttle" - Yuanqi valve, and seat belts were added. So even Cai Yan and Zhang Ling began to learn to open the machine car.

When Cao Mengde came, his eyes almost fell out when he saw this machine car.

He found Zhao Yu and was eager: "The machine car is of great use, can it be mass-produced?"

From Cao Mengde's perspective, of course, the magical use of the motor vehicle can be seen.

But Zhao Yu's answer extinguished his enthusiasm.

"The core of the machine car uses talismans, and cannot be mass-produced. If you abandon talismans, you will basically be a waste. You, don't think about it for the time being. Wait until I study it again, and if it can be mass-produced, I will not be stingy."

Cao Mengde had no choice but to sigh and give up.

Then we talked about the serious business.

"The soil gathering talisman given by the gentleman has been buried according to the nodes on the drawing. This..." He thought about it for a moment: "Is it really useful?"

Zhao Yu laughed: "At most half a month, it will be immediate."

"That's good." Cao Mengde breathed a sigh of relief. The two sat down in the yard. Cao Mengde said, "Sir, it was indeed wrong. Lu Bu went north. When he arrived in Chenliu, he saw that Zi Xiao had three thousand elite soldiers guarding him, so he went to Luoyang."

Zhao Yu nodded: "Isn't this obvious? Can't you guess?"

Then he said, "What? I don't believe you are here this time, that's all this little thing."

"There are two more things." Cao Mengde said: "One should I ask Mr., how are those young people trained?"

When Zhao Yu heard this, he nodded and said, "It's almost qualified."

It is about the 100 people sent by Cao Mengde during the Lantern Festival. A month ago, Zhao Yu was almost trained. Now this month is free to stock, so they will go to self-study. Otherwise, Zhao Yu would not have time to run a car.

These hundred people have been living in the fire courtyard, and they eat, drink and study. Ten people squeezed into one room. When Zhao Yu taught them knowledge, they were in the open space in the yard.

Zhao Yu spent a month and used the method of immortality to let them learn the Three Character Classic, Thousand Character Classic, Disciple Rules, and the basic mathematics and basic object research compiled by Zhao Yu. If the whole five books do not use their spiritual consciousness to activate the teaching of Taoist sounds, it would be a delusion to let ordinary people who don’t know a big word to learn it.

In addition, he also taught the skills of strengthening divine power in the external stage of the Thick Earth Kung Fu, allowing them to practice. Zhao Yu said: "You have read the Three-character Classic, Thousand Characters, Disciples Rules, as well as basic mathematics and object research. They can do it. Although the characters written are still unsightly, teaching elementary school is enough. In addition, I also taught the first part of the Thick Earth Kung Fu. I mean, children should develop comprehensively from an early age. Try to popularize the skills."

When Cao Mengde heard this, he looked happy: "Okay, sir, I'm tired."

Then he pondered: "Is this popular technique...are there a lot of disadvantages?"

Zhao Yu nodded: "I understand what you mean, but these are all trivial matters."

He said, "I have only taught Dian Wei in the Five Elements Boxing Classic. Every six months, you can choose some people who have made contributions from your subordinates, regardless of their civil and military affairs, and send them to me for further study. What do you think?"

Cao Mengde nodded immediately, this is a good thing, can he not agree?

Zhao Yu said again: "Daihe Villa has stabilized during this period. Look at what kind of children of the right age are there. Well... those under the age of fourteen, choose ten to send them to Villa. I'll see if there are any materials to make."

"good!"

Cao Mengde was extremely surprised and said, "My eldest son Cao Ang, this year's thirteenth, is just right!"

Zhao Yu smiled and said, "There is no limit on men and women."
Chapter completed!
