Although it was not early, and it was about time for the officials of various ministries to disperse, it was still about Shao Yi and Wu Jinshi, and the news of the convoy entering the city was still spreading rapidly.

Before, Qingyunzhai's two four-wheeled carriages went out of Beijing, which did not attract much attention, and many people thought that it was just flashy things, and there was nothing to see.

But at this moment, a convoy suddenly appeared, and thirty cars, each full of black gold stones, and thinking about the four-wheeled carriage, I immediately felt that there was something unusual in it.

It turns out that the two carriages are just a disguise, and the back hand is here. With the carriage that increased the transportation volume, it was hidden in the dark, knowing that the black gold stone had arrived in the capital, so it made a high-profile appearance, which made those who were looking forward to it and eagerly looking forward to seeing the lively Shao Yi How embarrassing!

There are also two departments, the Ministry of Household and the Ministry of Industry, and countless materials need to be transported every year. At this time, thirty four-wheeled carriages suddenly appeared, carrying heavy black gold stones, which was absolutely of great significance to the imperial court.

If this kind of carriage can be used by the imperial court, it can not only reduce the transportation burden of the imperial court, but also make some small benefits on a large number of updated carriages, which is not a trivial matter.

The wagons returning from the mining area were unloaded at the place designated by the imperial court, and the current Wujin stone was agreed to be deployed by the household department. Therefore, the Wujin stone site is no longer under the management of the Ministry of Industry, but transferred to the Ministry of Households.

During the unloading, the convoy drivers and the guards were more or less confronted with the exploration of some people, all asking about the key structure of this carriage, how the rotation between the wheels and axles remained smooth and without resistance.

For the wheel structure of the carriage, the driver and the guard have received some training to cope with the wear and tear and breakdowns that can occur on the road.

The marching fleet also carries spare wear parts for replacement in the event of a breakdown.

But when he came into contact with the four-wheeled carriage, the steward had repeatedly explained that this was a trade secret, and it was a new technology developed by Qingyunzhai craftsmen who spent a lot of manpower and material resources, and it could not be stolen by others.

Although the household department is an important department of the imperial court, the imperial court wants this technology, and the right way is for them to talk to the owner. Secretly ask them here about these hired people, that is, stealing, not high-grade!

Fortunately, those people in the household department are all official meals, and they are far less concerned about doing things for their own families. At this time, it is only a little temptation, it is best to ask and report to Shangguan, and you can always get some benefits.

It's reasonable not to ask, people are serious crafts, how can they tell others casually?

There are also those who are depressed because of this matter, those who have something to do with the black gold stone, or have something to do with it.

Originally, King Jing, Li Boyuan and others were still surprised, Mo Hong took the Li family steward to negotiate with the villagers, the purpose was only to clarify the truth of the matter, and did not mention the resumption of work and transportation roads.

According to the news sent back by the spies they left behind, the villagers and the mining area are still in a delicate state of confrontation, and the road is still potholed. Even some places seem to be flat, but they are just empty soil, and as long as there is a heavy object rolling over, it will definitely sink into it.

In other words, transport roads are still impassable.

But in Bei'an County, a smelting powerhouse under the jurisdiction of the capital, the black gold stone has been exhausted.

Just when they were puzzled, they were even ready, waiting to see if Shao Yi could not supply the Wujin Stone in time, and what would happen to the Ministry of Industry and the Emperor, the Wujin Stone was actually shipped back, and it was transported back in this way.

The advantages of the novel four-wheeled carriage, the unusually smooth wheel structure, and the improvement of transportation efficiency have won the attention of everyone up and down the capital.

The Wujinshi transport convoy only entered Beijing in the second half of the morning, and it was widely discussed that night. There is no discordant sound this time, the Xia women who can be criticized in the past are now brought out of the palace with the maids who come out of the palace. What you want to say, it depends on whether the emperor is willing to admit that the palace has no rules.

All of this, if you talk about feelings, there are only two words that the big guys can feel: powerlessness. No matter who they are, no matter what kind of stumbling block, they can't stop the other party's progress.

What else can be said but powerlessness?

The next day was the morning dynasty again, and after the daily report was over, the emperor called Qu Jiang, who had appeared in the morning this morning, out of the column and asked: "Will the supervisor send someone to follow Qingyunzhai's convoy to transport materials, and tell me about the situation they observed with the car, and how is the driving and stability of the four-wheeled carriage?" ”

Qu Jiang was waiting in Qingyun Zhai yesterday, and by the time the carriage unloaded and returned, it was already dark.

This person did not bother at all, and directly asked people to light lamps, candles, and torches, and in the darkness of the night, with a few craftsmen and officials who would be the supervisors, to inspect all the four-wheeled carriages involved in this transportation.

After confirming that everything was in good condition, a few more cars were randomly selected, the wheels were removed, the tiles of the plain bearings in front of the wheels and axles were removed, and the wear of the bearings was checked.

In the end, it was concluded that the carriage ran very well, with almost no wear between the bearings.

That is to say: the bearing structure is used in horse-drawn carriages, and the loss is not large. As a wearing part, the bearing is completely resistant to the wear and tear of the transport vehicle.

Qu Jiang's eyebrows danced and foamed at the mouth.

And the courtiers fell sharply.

The emperor actually knew about Qingyunzhai's four-wheeled carriage? Not only did he know, but he was also paying attention, and even did not hesitate to send the craftsman who would be the supervisor to follow the carriage and observe the driving condition of the carriage.

Many people are secretly wiping their sweat, but they really hope that Qingyunzhai and Shao Yi will be unlucky. Fortunately, they didn't know that Qingyunzhai had such a trip, if they knew, maybe one of them couldn't hold back, and they would send someone to arrange it on the road and do something irreparable......

Fortunately, there are still officials in the team who will be the supervisor, and the team that the emperor is concerned about. If you really send someone to make a fire, or pretend to be a gangster and do it, which one can run away under the vigorous arrest of the imperial court?

But this matter is just thinking about it, and it is still unknown whether it will be done or not. Two years ago, the glass transportation in Binh Duong County was blocked, and the big guys still remember it vividly. That incident caused the imperial court to take action, and almost cleaned the original gentry pattern of the six southeastern counties.

Wujin stone is related to the smelting of the imperial court, and unlike glass, which is only related to taxes, the imperial court will never tolerate someone to do the same.

In the various ideas of various people, Qu Jiang finished talking about the first time the four-wheeled carriage was running.

Among them, there are things they can understand, similar to horse-drawn carriages running very stably, and the carrying capacity is nearly doubled; There are also things that most people don't understand, what wheels, shafts, tiles, friction or whatever, it's completely in the clouds.

But the main meaning is clear, that is, the new axle has little wear and tear, and it is light to walk, so it can be widely used.

After a discussion of various people, it was quickly determined that the imperial court could try out some of the four-wheeled carriages first. After confirming that the driving is reliable, the old and new ones are replaced on a large scale.

When the matter was decided, the emperor said a word that almost shocked the courtiers into vomiting blood.

"Then the household department sent someone to Qingyun Zhai, and Qingyun Zhai owner to discuss, to buy the bearing technology. In the future, when the imperial court replenished the transport vehicles, it was made according to the four-wheeled carriage. ”

The courtiers were astonished: "Do you buy it with silver again?"
