Infrastructure masters in the red building

When Jia Fang came to Baigongfang, he was surprised to learn that the shower head he had delivered earlier had already been made—not only that, the coppersmiths of Baigongfang developed the supporting shower head without Jia Fang’s guidance at all. The faucet, copper pipe and water storage tank make a shower set.

The coppersmith triumphantly showed Jia Fang his finished product.Jia Fang smiled and watched him demonstrate: add hot water to the water storage tank, turn on the faucet, and the shower over there will spray out even fine water columns.

For a modern person like Jia Fang, it is not surprising that the shower can spray water.What's more, this device needs to manually heat hot water, manually pour the hot water into the water storage tank, and manually ensure that the water temperature meets the requirements... Otherwise, if it comes out of the shower, it will either scald the person's skin or irritate the body. People are covered in cold water.How can there be a fully automatic equipment with an automatic temperature control device in later generations that is easy to use?

But in the eyes of the craftsmen of Baigongfang, this is already quite remarkable.The coppersmith gestured here, while the porcelain burners, blacksmiths, carpenters...the top craftsmen of Baigong Workshop all surrounded them.Everyone looked curiously, and reached out to try one by one.Someone else asked in a low voice: "Using this to take a bath, compared with our big bathtub scrubbing towel... is there really such a big difference?"

The coppersmith laughed and said, "I don't know about this. I only know that there are dozens of households who have ordered orders. My apprentices and grandchildren have to be busy with this until May."

At the beginning, Jia Fang was still impressed by the creativity of these craftsmen and the marketing ability of Baigongfang. Who knew that his elder brother Jia She had ordered ten sets of this so-called "lotus bath set" at once. .

Jia Fang: "Please everyone... give my brother a discount!"

Shopkeeper Ren patted his chest and agreed: "It should be the case. The goods delivered to the family will only be charged at the cost price." He also ordered to send a set to Jia Fang's courtyard as soon as possible.

"Third Master, don't you really want the little ones to help you spread the word... Did you actually come up with this idea?" Shopkeeper Ren asked in a low voice.

Jia Fang shook his head vigorously: "It was agreed in the morning that this idea is all from your Baigongfang, it has nothing to do with me, it has nothing to do with me!" He made up his mind early in the morning: these things are produced by Baigongfang. It is more appropriate for him to come forward, and the effect will be better.

Seeing Jia Fang's insistence, the shopkeeper Ren didn't say any more. After thinking about it, he said to Jia Fang: "My boss is not in the workshop these days, but I have something to say. If you want to find him, you can go directly to the Beijing Palace. .”

Jia Fang shook his head, "I'm not here to find your master, but to find a few master craftsmen."

Shopkeeper Ren repeatedly said, "Don't dare to do it, don't dare to do it", but several craftsmen rushed up together, surrounded Jia Fang, and asked with a smile: "My good third master, is there anything new for us to make?"

Jia Fang smiled: "This time I want to ask the two big brothers who are good at ironwork and woodwork." When he said "ironwork" and "woodwork", he actually meant blacksmiths and carpenters.

When Jia Fang said this, the blacksmith and carpenter were overjoyed, and the other craftsmen showed disappointment.

Unexpectedly, Jia Fang added another sentence: "We need to invite some strong masters to help!"

Originally, the face of the coppersmith was already full of disappointment, but when he heard the last sentence, he was immediately overjoyed, and quickly patted the thick muscles on his chest, saying: "My old boy, there is nothing else, I have a lot of strength, the third master ordered me to come down." that is."

It wasn't until Jia Fang took out the drawings and reported the dimensions that the craftsmen realized what kind of challenges they were facing.

What Jia Fang has to do is: the section is a long straight iron piece with an I shape, and each iron piece needs to be at least two feet long.In addition to this, there are wooden sleepers, which are used to support the track and at the same time can fix the position of the track.

"This is really a big piece!" The craftsmen who saw the drawings all sighed with emotion.

Jia Fang finally realized that he might have overestimated the technological level of ancient technical jobs: relatively mature iron-smelting technology and relatively rudimentary steel-making technology have appeared in this time and space, which can produce a kind of steel called "iron steel". , but it is only used to produce farm tools and a part of military supplies, and the specifications are small.

In other words, it is technically impossible to make such a large-scale steel rail as Jia Fang requested.

But this did not bother the craftsmen, a group of craftsmen discussed it in a hurry, and finally proposed to use bronze as the material and try to cast it by pit method.

The craftsmen here were discussing in full swing, while the shopkeeper Ren invited Jia Fang aside, and asked cautiously: "Third Master, my master's family has issued strict orders. What the Third Master wants to do, the younger one is not qualified to ask. But this ..."

Shopkeeper Ren pointed to the blueprint that Jia Fang had laid out on the table in embarrassment, "What is this for?"

Jia Fang laughed, and said, "Everyone has curiosity. But, Shopkeeper Ren, I really want to make a fool of myself this time. Wait for the first pair of rails... no, it looks like copper rails now, wait Once they're made, you can figure out what it's for."

Under the operation mode of Baigongfang, the execution ability of the craftsmen is amazing.Within two days, two two-foot-long bronze rails were really cast.

Jia put it in the backyard of Baigongfang and did an experiment with two carriages.

Two sections of copper rails were laid on the ground, and the wheels of one of the carriages were modified so that they could just fit on the two tracks; the other carriage was placed directly on the flat ground.

Jia Fang ordered people to pile a thousand catties of heavy objects on the carriage, and then asked the two mules to pull the carriage forward.

The mule moved the cart placed on the copper rails lightly; as for the cart placed directly on the flat ground, the coachman yelled loudly to drive the mule, and the mule lowered its head, as if exerting all its strength to drag the cart. After taking two steps, he raised his head and yelled "Hang Chi" and "Hang Chi" several times, as if he was begging for mercy, and also seemed to be complaining: who can drag it so heavy...

Jia Fang then ordered the mule to be unloaded from the cart, and ordered the two carts to be reset. Then he looked back at the craftsmen and asked, "Who wants to try?"

try?Try dragging this heavy vehicle with a thousand catties of weight with bare hands?This - can it be done?

Most of the craftsmen showed disbelief, but the coppersmith and Jia Fang cooperated the most. They simply took off their outer clothes and put on only a close-fitting gown, showing a pair of strong arms. They stood in front of the car, Shen Said: "My old boy, come and try."

Needless to say, the coppersmith spent a lot of effort to drag the truck on the flat ground five or six feet away.But as soon as it was changed to the copper rail, the coppersmith easily dragged the truck two feet away amidst the exclamation of his companions without much effort.

During the experiment, Jia Fang and Shopkeeper Ren watched the whole process.

"I think, at this time, you should understand why I did this." Jia Fang said.

Shopkeeper Ren was still in shock, unable to recover.

At this time, the craftsmen had already surrounded Chao Jia Fang, and asked Jia Fang to "talk" to them—these craftsmen knew Jia Fang's ability, and they could explain the truth behind everything. .

Jia Fang was generous, and told everyone the principle of friction and friction coefficient, trying to use plain language that the craftsmen could understand.

Everyone has never heard of the term friction, so Jia Fang used "resistance", and the coefficient of friction couldn't be directly used. Jia Fang used "resistance factor", but he explained while making gestures, and led everyone to think of ice in winter. The surface, the road covered with gravel and sand... Although a craftsman who has no concept of physics in junior high school, he gradually seems to understand something.

Shopkeeper Ren, who was waiting at the side, became more emotional the more he listened to it——Jia Fang only asked people to make two-foot-long copper rails, but shopkeeper Ren was very active, knowing that Jia Fang would definitely make people make copper rails that were tens or hundreds of feet long. track for the transportation of heavy objects.

Even if Jia Fang didn't do it, his boss would have to start work: These two copper rails look ordinary, and to build a short section of such a road in Beijing, the common people would at best have a fresh idea.

But if such things are placed in mines, docks, and warehouses... how much manpower and animal power can be saved!

Shopkeeper Ren was thinking about it, and at the same time he was beaming with joy and exaggerated his expression.He didn't know that Jia Fang saw all the expressions of shopkeeper Ren.

Of course Jia Fang knew what kind of changes the orbit might bring to this time and space, and he had no intention of disturbing the imagination of shopkeeper Ren—but he planned to ask these master craftsmen to meet his needs in the Grand View Garden.

He needs copper rails with a total length of two hundred feet, and several pairs of bronze wheels, which can be disassembled at will - he does not want to install a small sightseeing train in the Grand View Garden. At present, Jia Fang's ambition is only limited to: strengthening the interior of the Grand View Garden If any goods are really delivered to Daoxiang Village, these goods need to be transported out of the Grand View Garden without the outside world knowing as much as possible.

Therefore, Jia Fang boldly placed the order.

Shopkeeper Ren also responded proudly: If Baigongfang can't even agree to this, then don't think about the future.

Jia Fang came to Taoyuan Village again through the "Shrinking Ground Whip" in Daoxiang Village.

As soon as he arrived this time, he found that the villagers were chanting and dragging one after another of the fir trees with bark up from the river.This kind of fir is about as thick as a sea bowl, straight and straight, and each tree is three or four feet long.

It seems that the newly widened "Qingfang River" in Taoyuan Village has become a good way to transport this kind of wood.

"What is this going to do?" Jia Fang asked the old village chief who was directing the villagers to work on the spot.

The old village head replied enthusiastically to Jia Fang: "This kind of tree is called iron shirt. The wood at the core is as hard as fine steel. Everyone bought some from the upstream village, which can be used to transport goods." trail of."

As he said that, the old village chief made gestures to Jia Fang: "Cut it so thick and wide, lay it on the flat ground, and turn around, the vehicles will walk on this track. It saves a lot of energy than walking on the flat ground!"

Jia Fang: ...

How can you know what I am doing? Not only do you learn from others, but you also know how to adapt to local conditions?

He insinuated vigorously, wondering how the old village chief came up with this idea.If the old village chief still said that it was Jia Fang who said it this time, he is absolutely sure that he can jump out and refute it-this is definitely not what I said.

Unexpectedly, the old village chief said that it was a shopkeeper passing by the village who suggested this idea.It happened that someone upstream cut down the hemlock, so the old village chief made his own decision and started to act.

Jia Fang didn't show it on the surface, but the shock in his heart was no less than when he first discovered this Taoyuan Village—is this really, a mirror world?

He planned to see how the villagers made the hemlock into wooden rails, but the old village chief finally showed his timidity at this moment: "Third Master, Third Master, please give us some advice!"

"The peddler just suggested a method, how to do it... We don't know how to do it!"
