Yang Yu didn't know that Lu Dao's unintentional actions had caused such a big wave to the officials of Daxing, even if he knew Lu Dao, he wouldn't care.

Because seizing power and changing the fate of the puppet emperor was originally his goal, and in order not to repeat the mistakes of the past, he had to take this step.

After the morning pilgrimage, Heihiro returned with good news, and only five days later, the first four-wheeled carriage had been installed.

After getting the drawings last time, Hirahiro returned to the Ministry of Works, and immediately gathered the few skilled craftsmen together to overcome the difficulties collectively, and based on the ready-made drawings, the first four-wheeled carriage was made in only five days.

Yang Yu was enthusiastic and followed the return of the Ministry of Works, Pinghong, to the Imperial Supervisor.

Many ministers were quietly paying attention to Yang Yun's movements, and soon received the news that Yang Yu had arrived at the Ministry of Industry.

couldn't help but be in an uproar, I didn't expect His Royal Highness the Acting King to move so fast, and quietly brought the Ministry of Works under his command.

The status of the Ministry of Industry in the court has always been low, and Ping Honggui's life in Daxing is not easy, but now the form of winning the heir is still unclear, why did he get into it in a daze! 、

The princess of His Royal Highness's mother's throne has a higher status, and the possibility of succeeding to the throne is not small, after all, Yang Yu is only a thirteen-year-old child, and he is the youngest of the three brothers in the prince's lineage.

Many ministers were confused, and they didn't know what they were thinking in their hearts.

Ping Honggui didn't think about these at all, and he was always intoxicated with the joy of the success of the four-wheeled carriage, but he solved the problem for hundreds of years, and the first four-wheeled carriage in the whole world was born in his hands.

"Meet His Highness the Acting King."

In front of the Imperial Horse Prison, one hundred and ten craftsmen appeared at the door and bowed when they saw Yang Yu appear.

The Imperial Carriage Supervisor is a place dedicated to the production of chariots for the royal family, and the royal chariots and horses have always been built by the Imperial Horse Supervisor, and the task of this four-wheeled carriage was also built by the Imperial Horse Supervisor.

However, with the eastward relocation of the imperial capital, the once glorious imperial car supervisor gradually lost its former style, and after the imperial car supervisor of Luoyang picked away a large number of skilled craftsmen, it soon declined.

In less than two years, it was merged with the Ministry of Industry of Daxing, and now the Imperial Supervisor survived under the protection of the Ministry of Industry, and only received one task in the last two years, that is, this time Yang Yu's carriage to Luoyang, which can be described as extremely miserable.

The most unfortunate thing is that the carriage they did their best to build for His Royal Highness the Acting King went wrong in the end, causing a serious illness of His Royal Highness the Acting King, and everyone was uneasy in their hearts.

Fortunately, with such an opportunity to atone for his sins, the Ministry of Works sent His Royal Highness the Acting King's request for a carriage, how not to do his best to build a carriage that His Royal Highness the Acting King likes.

This is related to the future fate of the Imperial Commander, to create a carriage that His Royal Highness is satisfied with, and to fight this turnaround battle, it may not be possible to reproduce the glory of the Imperial Supervisor of Daxing.

All the craftsmen worked overtime, and finally built it in the shortest time, and notified His Royal Highness the Acting King to come as soon as possible.

"No courtesy."

Yang Yu raised his right hand.

Although the Imperial Inspector is an important place in the government, it is relatively safe.

But Dong Yue, the commander of the guards who had been accompanying him, did not give up his vigilance, and only after re-checking did he let Yang Yu enter.

Dong Yue is about thirty years old, with a tiger's back and a bear's waist, and it is the year of the fight, and he is very cautious about Yang Yu's safety.

The people of the Imperial Carriage Supervisor did not care, in the past, when the Imperial Carriage Supervisor was glorious, the pomp and circumstance of the emperor every time he came was much bigger than this.

The imperial car supervisor, who had not met such a guard of honor for a long time, not only did not complain, but became a little excited.

Under the leadership of Ping Honggui, Yang Yu entered the imperial car supervisor and came to a flat open space.

"Your Royal Highness, please take a look."

In the middle of the clearing was a brand-new four-wheeled carriage, beside which were four horses of all white colors, all of which had been pulled up and ready to be driven.

Yang Yu approached and gently touched the brand-new carriage with his hand, which was the first thing he had made that had derailed from this world.

Although the two-wheeled carriage is now the mainstream in the Sui Dynasty, the four-wheeled carriage is the royal road because his direct four points touch the ground, which can reduce the weight of the horse by half and make the horse's ability to exercise more durable.

The weight of the horse is lighter, and the natural load, speed and distance will increase.

"Yes, yes, I didn't expect you to build it so quickly." Yang Yu praised.

"His Royal Highness the Acting King is ashamed of his subordinates, if it weren't for the unique creativity of His Royal Highness the Acting King, our Ministry of Industry and the Imperial Supervisor would not have been able to think of such a perfect carriage even if they wanted to break their heads." Hirahiro returned to flattery.

"Okay, don't talk about these empty words anymore, the four-wheeled carriage Qin Dynasty already has it, where is this king's idea."

Ping Honggui was not embarrassed to be broken, he smiled, and continued to introduce the carriage to Yang Yu.

"Your Royal Highness, please see, this is the shock absorber you requested, but the object called the spring painted by His Royal Highness the Acting King is too delicate for the Ministry of Engineering to make it yet. I had to resort to this stupid method. "

Yang Yu leaned over, looked at the shock absorber made of the principle of iron sheet 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.

Seeing that Yang Yoo was not angry, Ping Honggui breathed a sigh of relief and continued to brake the device for Yang Yoo.

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 have long been collected by the Imperial Horse Supervisor, and the idea of the shock absorber is derived from the four-wheeled carriage of the Qin Dynasty.

The reason why it took nearly five days to complete was that the biggest difficulty was on this brake, but fortunately, this problem was overcome after the most difficult time, and the method of hand brake was adopted.

This made Yang Yu 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.

What surprised Yang Yu the most was that these craftsmen perfectly solved the problem of four-wheeled carriage steering.

Yang Yu originally painted the form of a handlebar like a bicycle, and the clever Da Sui scientists placed a coachman's position on the wheel, with two pedals under the driver's feet, and the pedals were connected to the front axle, so that the coachman could easily control the steering of the carriage with the help of the force under his feet.

Yang Yu circled around the four-wheeled carriage and nodded with satisfaction.

To put it bluntly, this is the most advanced carriage of this era.

Yang Yu personally sat up, Dong Yue stepped forward and put on four horses, the four horses were already impatient,

"Driving"

Dong Yue drank in a low voice, and the four horses started slowly and began to run around the open field.

The ride is very smooth, the suspension is good, and there is almost no bump like a two-wheeled carriage.

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

"Phew"

Dong Yue slowed down the carriage, pulled down the hand brake on the left hand, and the carriage stopped steadily in its original position.

"Yes, all the craftsmen who participated in the construction of this four-wheeled carriage will be rewarded."

Yang Yu jumped out of the carriage and said happily.

"Thank you, Your Highness."

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

"Ping Shilang has worked hard."

"The old minister doesn't dare to take credit," Ping Honggui said modestly.

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

Ping Honggui couldn't help but be dumbfounded, according to his understanding, the royal creation of things has always been not a cost. This workmanship, this wood, are all top-notch, and the value is really hard to estimate.

His eyes motioned for an old craftsman to step forward, this was Xie Ji, the head craftsman of the Imperial Carriage Supervisor, and he supervised the construction of the four-wheeled carriage.

"Your Royal Highness, the materials used in your carriage are all of the highest quality, and the value of wood alone is more than fifty yuan.

Yang Yu estimated that fifty yuan is not a small amount in this era.

"What if we use some precious but common materials for mass production?"

"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."

Xie Ji was a little inexplicable, and he didn't know why His Royal Highness the Acting King of Lu Dao would ask these questions, because the royal production of things has always been costly, as long as the most expensive, not the best.

"Build a royal car for the emperor's grandfather first, and strive to send it to Jiangdu in the shortest possible time." Yang Yu thought about it for a moment and said, "Then build ten of the top carriages." ”

"Yes, on the orders of His Royal Highness the Acting King."

Ping Honggui agreed happily on the surface, but in fact, his heart was dripping with blood, and these eleven carriages directly hollowed out the Ministry of Engineering. ”

"This Wang Zhilu Dao Ministry of Industry has a thin foundation now, but it will not be long before the Ministry of Industry will become the richest department." Yang Yu sold a pass.

Ping Honggui was confused, but Xie Ji looked at the four-wheeled carriage thoughtfully.

"What does His Royal Highness mean to allow us to make a four-wheeled carriage for profit?" Xie Ji said tentatively.

"Not bad"

After receiving an affirmative answer, Xie Ji burst into tears of excitement.

"Thank you, Your Royal Highness the Acting King, for giving us a way out of the ministry." Hirahiro also reacted and choked up.

The reason why the Ministry of Industry is poor is that there has been no government order, and now with the secret weapon of the four-wheeled carriage, with the craftsmanship of the Ministry of Industry, it will not fail.

"Just how much does this four-wheeled carriage cost?" Xie Ji asked.

"Thirty times." Yang Yu's words are not shocking, and he is endless.

"Thirty runs?" Xie Ji and Heping Honggui exclaimed.

A four-wheeled carriage made of precious wood costs ten times, and a car can make a profit of twenty times, and if you throw away labor and tribute to His Royal Highness the Acting King, how can it fall into the pocket of the Ministry of Works.

Ten cars a day, is a hundred, a month is three thousand, this income alone can make the Ministry of Industry live a very moisturizing life, enough to make all departments red, when the time comes, their mortal enemy, Luoyang's Ministry of Industry will definitely reach out.

"But if you want to keep this hen that lays golden eggs, you can only rely on one person, and that is His Royal Highness the Acting King." Ping Honggui said secretly in his heart.

He knew that this was a shameful opportunity, and from now on he would be marked as a king, but so what? From his two contacts, His Royal Highness the Acting King is the only candidate for the throne, so what if he fights himself.

"But this four-wheeled carriage can only be used in the city, once out of the city, it is not as flexible as the two-wheeled carriage, will anyone pay thirty yuan to buy it?" Although Xie Ji was also very excited, he still raised his own professional questions.

"Why didn't anyone buy it? This four-wheeled carriage is comfortable, safe, more comfortable than riding a horse, faster than riding a sedan chair, and it is our only business, do you say anyone will buy it? "

Yang Yu said happily, how could no one like the carriage that made him excited. A good car is a temptation that is hard for men to resist in any era.

Although thirty guan is an astronomical amount for ordinary people, for those officials and big businessmen in Daxing City, 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 a 'BMW' four-wheeled carriage in the future." Yang Yu waved his hand.

This is a wonderful opportunity to befriend the officials, Ping Honggui added from the bottom of his heart, he has been in the officialdom for a long time, and he can see at a glance that there is another huge market for this four-wheeled carriage.
