Since Zhao Dezhao talked about the shortcomings of the Great Song Dynasty's current navy, four days have passed, and today Zhao Dezhao was just about to return to the palace, and met Li Qing, who would be a prisoner, at the gate of the palace.

Zhao Dezhao immediately walked up, saw Li Qing, and knew that Li Qing had come here in a hurry, and it must be for that matter, so he hurriedly asked: "Li Qing, how is the four-wheeled carriage, is it already?" ”

Li Qing arched his hand, "Your Highness, Weichen is here to inform Your Highness of the good news, the four-wheeled carriage that will be made by the supervisor has been successful, please go and inspect it." ”

Zhao Dezhao was very excited when he heard the news, he patted Li Qing's shoulder and said, "Hmm! Thank you for your hard work, take me there now. ”

After speaking, Zhao Dezhao came to the general prison under the leadership of Li Qing. At this moment, at the gate of the prison, one hundred and ten craftsmen stood on both sides of the road, and when they saw Zhao Dezhao appear, they immediately bowed and saluted.

"See Your Highness."

"Everybody, please stand up and speak." Zhao Dezhao raised his right hand.

And what he is most concerned about now is the four-wheeled carriage, which has been in place according to Li Qing on the way here, and is waiting to be checked.

"Your Highness, the four-wheeled carriage is here." Li Qing led Zhao Dezhao to a place in the backyard of the prison.

Zhao Dezhao raised his head, only to see a red cloth covering a huge thing in the clearing, presumably it was a carriage, but Li Qing pretended to be mysterious and draped red silk on the outside of the carriage.

Zhao Dezhao walked quickly to him, left Li Qing behind, lifted his right hand, and when the red cloth fell, his eyes caught a glimpse of the well-made four-wheeled carriage, which brought Zhao Dezhao a shocking feeling at this moment.

At this moment there was a brand-new four-wheeled carriage parked in the clearing, and beside it were four swarthy horses, all of which had been pulled up and ready to be driven.

Zhao Dezhao looked up at this object and gently touched this brand-new carriage with his hand, which was the first thing he had made that was derailed from this world.

"Your Highness, please see, this is a four-wheeled carriage." Li Qing pointed to the carriage and said happily.

"Yes, I just don't know if it's comfortable to sit?" Zhao Dezhao looked at his appearance, and he could see that the craftsmen had put a lot of effort into it.

This car is handmade, if it comes out must be a high-priced thing, and he also plans to use this thing to build a public transportation system in Kaifeng City, which is intended to be used for people's transportation, and also brings convenience to the people.

Nowadays, the two-wheeled carriage was the mainstream in the Song Dynasty, but Zhao Dezhao, who came from later generations, knew that the four-wheeled carriage was the king, because his direct four points touching the ground could reduce half of the horse's load, making the horse's ability to exercise more durable.

The weight of the horse is lighter, the natural load weight, speed and distance are improved, and the stability is better than that of the two wheels.

"Yes, yes, I didn't expect you to build it so quickly, it's really surprising to this king." Zhao Dezhao praised and glanced at Li Qing.

Li Qing smiled, lowered his head, and flattered: "Your Highness is ashamed of your subordinates, if it weren't for Your Highness's unique creativity, the Ministry of Industry and the General Supervisor would not have been able to think of such a perfect carriage even if they wanted to break their heads." "

"Okay, don't talk about these empty words anymore, the four-wheeled carriage Qin Dynasty already has it, where is this king's idea." Zhao Dezhao suddenly felt that these people's sycophants were really filmed to the extreme.

Li Qing was not embarrassed to be broken, he smiled, and continued to introduce the carriage to Zhao Dezhao.

"Your Royal Highness King Liang, please see, this is the shock absorber you requested, but the object called the spring painted by His Royal Highness King Liang is too exquisite, and it has not been made for the time being. I had to resort to this stupid method. "

"Hmm!" Zhao Dezhao also knew that there were some things that could not be forced to be made by them, and the spring had particularly high requirements for the process, and it was not made by breaking through the technology all at once.

Putting aside this thing, Zhao Dezhao saw the carriage at this moment, and then leaned over, looked at the shock plate made of the principle of iron tension, and nodded, it would be good to have it, as for the spring, it will always be able to be made in the future.

Li Qing was relieved to see that Zhao Dezhao was not angry, and continued to brake for Zhao Dezhao. "Your Highness, this is the brake pad you asked to make......"

The brake system is the simplest principle, but it is the most difficult of all objects to make. In fact, the drawings of the four-wheeled carriage will be collected by the superintendent, and the idea of the shock absorber comes from the four-wheeled carriage of the Qin Dynasty.

And these days, these craftsmen spent three or four days, barely completed this thing, the biggest and biggest difficulty is in this brake, fortunately, in the end spent a huge amount of manpower energy, or to overcome this problem, using the hand brake method.

This made Zhao Dezhao a little ashamed, he didn't expect that what he casually ordered, which seemed easy to him, would cause such a big difficulty to these craftsmen.

And Li Qing on the side at this moment, his throat was also a little dry, and he had a slight pause in his speech, Li Qing also introduced Zhao Dezhao for so long, Zhao Dezhao instructed the craftsmen to bring a glass of water and hand it to Li Qing. Li Qing was at a loss, and reluctantly handed the water cup from Zhao Dezhao's hand.

Zhao Dezhao continued to circle around the four-wheeled carriage and nodded with satisfaction.

At this time, Zhao Xin also arrived to be the prisoner.

"Zhao Xin, you're here too." Zhao Dezhao asked.

Zhao Xin arched his hand and said, "Your Highness, the minister heard that His Highness will be a prisoner, and he was worried about His Highness's safety, so he rushed over." ”

"If you think about it, these carriages are safer and smoother than the others. Zhao, if you don't believe it, I'll let you try the feeling of sitting on it later. ”

Then Zhao Dezhao planned to test the various properties of this carriage, he was already impatient and wanted to try it himself, and he instructed Zhao Xin to take the whip and sit in front of the carriage to direct the carriage.

Zhao Dezhao immediately let Li Qing sit up, Zhao Xin stepped forward and put the carriage on the four horses, at this moment the four horses were already impatient, Zhao Xin sat at the head of the car, ready to whip.

Li Qing pushed Weiwei and sat in the same car with Zhao Dezhao. He felt honored, but he also felt that Yu Li was incompatible, but Zhao Dezhao pulled him into the car.

"Drive!" After Zhao Xin saw the person sitting firmly, he could wave the horsewhip and drink in a low voice. The four horses began to start slowly, and began to run around the open field.

Zhao Dezhao and Li Qingzheng were sitting in the carriage, and Zhao Xin was only waiting to carefully control the carriage and try to make the carriage very stable.

In the car, Zhao Dezhao didn't feel a trace of bumps, he asked people to bring a water cup, fill it with water, and then place it on the table in the car.

Li Qing sat in the car nervously at first, but Zhao Dezhao smiled when he saw his bear-like appearance, and after the carriage started to drive, it was also very stable, and Li Qing let down his guard.

If the two-wheeled carriage had been started, all the water in the cup would have spilled and overturned, but this four-wheeled carriage was more stable than the two-wheeled, and there was very little splashing in the cup.

Zhao Dezhao looked at the cup with satisfaction and sat in the car with satisfaction, but Zhao Xin's speed was not fast enough, presumably because he was worried about his safety.

The four-wheeled carriage runs very smoothly, the shock absorption measures are very good, and there is almost no bump like the two-wheeled carriage.

Zhao Dezhao opened the door curtain, and then said, "Zhao Xin, hurry up." ”

Zhao Xin had no choice but to carry out the order, and also slightly accelerated the speed of the carriage, but it was still stable in the car, even Zhao Xin, who was sitting outside with a horse whip and driving the car, also felt very stable, and he also felt in his heart that this car brought him a different feeling from other cars.

And Li Qing was shocked, now the speed of the vehicle is faster, but the car is still as stable as ever, and Li Qing is relieved.

Zhao Xin then sped up the speed of the carriage again, only to see that on the open space that would be used as a prison, the carriage began to move, and the car occasionally saw shaking, presumably the four-wheeled carriage still had some defects, but everyone would be amazed by this car.

"Your Highness, this car is really stable." Li Qing let out a heartfelt sound of admiration.

Zhao Dezhao sat on the carriage and felt the speed of the carriage, this was already the tenth lap of the race, and the horse's speed did not slow down in the slightest.

"Almost." Zhao Dezhao, who was sitting in the car, gave an order.

"Phew—"

Zhao Xin slowed down the carriage and pulled down the hand brake on the left hand side, and the carriage stopped steadily in its original position.

Zhao Dezhao shook his sleeves, jumped out of the carriage, and then instructed Li Qingdao: "Yes, all the craftsmen who participated in the construction of this four-wheeled carriage will be rewarded." "

"Thank you for the reward for those craftsmen!" Li Qing bowed.

"Thank you, Your Royal Highness King Liang." The craftsmen couldn't help but be overjoyed, as craftsmen, their salaries were also pitiful, His Royal Highness King Liang has always been generous, and the rewards will definitely not be less.

"This carriage is very fond of the king, I don't know how much the carriage costs?" Zhao Dezhao asked.

Li Qing couldn't help but be dumbfounded, according to his understanding, the royal family has always been not costly. This workmanship, this wood, are all top-notch, and the value is really hard to estimate.

"His Royal Highness King Qiqi Liang, the materials used in your carriage are all top-notch, and the value of wood alone is more than ten times."

"What? So expensive. Zhao Dezhao said in horror, estimate, ten yuan is not a small amount,

"This king will need to build a lot of this in the future, and you must keep the price down, and the material can be replaced by other wood."

"If it is produced in large quantities and some common precious wood is used, the cost can be controlled within 10 yuan, and the output can reach 10 cars per day." Li Qing was a little inexplicable, and he didn't know why His Royal Highness King Liang asked these questions, because the royal production of things has always been costly, as long as the most expensive, not the best.

"How much does this carriage cost?" Zhao Xin asked.

"Thirty times." Zhao Dezhao's words are not shocking, and he is endless.

"Thirty runs?" Li Qing stood there and exclaimed, "But this four-wheeled carriage can only be exercised in the city, once it goes out of the city, it is not as flexible as the two-wheeled carriage, will anyone pay thirty yuan to buy it?" "

"Why didn't anyone buy it? This four-wheeled carriage is comfortable, safe, more comfortable than riding a horse, faster than a sedan chair, faster than a donkey cart or a mule cart, and it is our only business, do you say anyone will buy it? Zhao Dezhao said happily, how could no one like the carriage that made him excited. A good car is an irresistible temptation for men in any era.

Although thirty-five guan is an astronomical number for ordinary people, for those officials and big businessmen in Kaifeng Fucheng, thirty guan can be said to be a drop in the bucket.

"And this king has already given it a name, and it will be called 'Mercedes-Benz' four-wheeled carriage in the future." Zhao Dezhao raised his head and said.

"Mercedes-Benz, good name." Zhao Xin and Li Qing exclaimed.

After that, Zhao Dezhao ordered someone to bring paper and pencils, and he drew the design of the rickshaw and handed him over to Li Qing, but for this thing, it is indeed much simpler than the four-wheeled carriage, and this thing only needs labor, and at present, there are many laborers in Kaifeng Prefecture, and it also needs manpower to complete.

After Li Qing saw it, he nodded in admiration.

Rickshaws, for manpower use, and can also create employment opportunities for some unemployed homeless people, and rickshaws are stable, although not as fast as horse-drawn carriages, but safe, and can also walk through the streets in narrow alleys.

After that, Zhao Dezhao played the four-wheeled carriage, rickshaw and Kaifeng's public transportation design plan to Zhao Kuangyin, and after Zhao Kuangyin listened, he also personally tried the different experiences brought to him by the four-wheeled carriage and rickshaw.

In view of the difference between the two types of carriages mentioned by Zhao Dezhao, the four-wheeled carriage can not only be sold to eunuchs and merchants, bringing a large amount of income, but also can be used as a public transportation business of the imperial court, governing the imperial court departments, and also bringing huge benefits to the treasury revenue.

Zhao Kuangyin thought about it and agreed to Zhao Dezhao's request, and then ordered that a batch of four-wheeled carriages and rickshaws designed by the general supervisor be used in Kaifeng traffic to improve the pain of the people's travel, and the four-wheeled carriage also became a backup for transporting materials.

This property is temporarily under the jurisdiction of the Ministry of Industry.

Then the four-wheeled carriage and rickshaw appeared on the Kaifeng cement road, as Zhao Dezhao said, it changed the concept of people's travel, solved the problem of labor employment, and also provided convenience for the people to travel, and at the same time the income of the imperial court also increased a lot.

Under the operation of the imperial court, Kaifeng's bus lines have opened up a lot.

After Zhao Dezhao also sold a lot of four-wheeled carriages to Wu Lingqing, as an old friend, he sold them at a friendly price, and the martial arts car dealers ordered this vehicle in large quantities, becoming the first object of the imperial court to buy four-wheeled carriages.
