The invention of every tool will cause a wave of scientific and technological progress!

After the invention of this 'manual threading machine', I began to arrange for craftsmen to install water pipes in all the buildings in Baiyucheng.

Anyway, the holes in these pipes were reserved long ago when they were being built. So soon at least one connection to the water pipe was installed in every house. Of course, because the rubber has not yet been found, the faucet can only be used from the ready-made goods in the mall for the time being.

The structure of the faucet is extremely simple, and it can be easily made by forging. However, without a sealed rubber ring, the faucet will not close perfectly.

Although research has found that there are also faucets designed with ball valves and new faucets sealed with ceramic sheets. However, these two are difficult to make with existing technology. Among them, the round ball in the middle of the ball valve faucet needs to be handmade by the lathe little by little. But now the lathe is not so accurate and easy to use~ After all, this thing is just a copy of me according to the appearance in some games. I have never seen a real lathe in my later life.

The yield of hand-made ball valves is too low, and basically one hundred and ten can barely produce a steel ball of the right size as the core component of the ball valve.

In the new faucets used in later generations, they are all sealed with ceramic sheets, although the ceramic thing is easy to make, but it is used to make faucets~ It seems that the fineness is still a lot worse, and it can't be sealed!

If you can't come up with a good idea for the time being, you can only use ready-made goods from the mall...... Therefore, after installing a rough-looking cast water pipe that has not yet been painted, a very beautiful and delicate faucet is installed on every house in Baiyu Chengli. It's still the kind of silver that can reflect the figure of a person. For this reason, each noble family also strongly requested that more ...... be installed in their homes

I've been worried about this for a long time! After all, if the goods in the mall are directly taken out and used, when the mall is refreshed every day, gold consumption is needed as a supply. And I supply all the faucets of a city by myself~ That amount really makes me almost unbearable! I estimated that based on the various styles on the counter in the mall, there are less than 100 of them that can be used as ordinary faucets. It takes years to refresh every day to come up with enough faucets for the city to need!

Fortunately, this matter was quickly solved by the people of Lubanmen, and after they found out about my difficulties, they actually used wood and bamboo to make a completely leakless faucet by hand! Anyway, I really underestimate these carpenters. And the appearance of this wooden faucet is really a big thing that has troubled me!

However, if the wood and bamboo have been soaked in water, I am still a little worried about the durability of the soaked water. Although the people of Lubanmen have a secret method to make both wood and bamboo completely waterproof. Similar to some kind of paint or wax or glue. However, the cost of this technology is still quite large. The people from Lubanmen didn't tell me the specific formula, but after I went back and asked Nie Xiaoqian, although she didn't tell me the exact formula, she also made it clear that this secret method requires a lot of very difficult materials to make secretly. It also looks like it's worth a lot of money.

So under my guidance, I finally succeeded in making the most old-fashioned cast iron faucet, which is all cast iron and requires a rubber ring to repel waterproof. Because the rubber is still not obtained, the faucet that has been renovated this time uses small wood chips and small bamboo chips to replace the rubber ring inside. Although the durability of this is still not as good as that of a real old-fashioned faucet, the main structure of the cast iron makes it possible to replace the bamboo and wood chips inside the faucet after the problem begins to leak, similar to the way the rubber ring is replaced in the old faucet in the mall......

In this case, I only need to match each faucet with a few sets of wood chips and bamboo chips, and the faucet will be safe to use for a long time! Therefore, the water supply and water supply system in the entire White Jade City can be regarded as a complete solution. Because of the emergence of new technologies for bamboo and wood chips instead of rubber ring sealing. Even the problem of a 'flush toilet' that was bothering me was completely solved. Now all the buildings in the entire White Jade City are not only installed with running water, but also sewers and standard-looking flush toilets. After all, the main structure of the flush toilet is ceramic, and ceramic technology is an easy thing to do in Datang......

"Haha! Finally one thing has been solved, then, the next step is to try to solve the power problem! "I said after inspecting the water supply and drainage system installed in Baiyu City with satisfaction.

Speaking of which, this white jade city has been built since it was built. It was soon bought by various nobles and well-informed people in Datang at a high price. And I was left with only a four-story residential building. I bought it myself.

In other words, this white jade city was obviously built under my design guidance and took a month to build. However, the conscripts and some craftsmen and workers who contributed here, as well as all the building materials, were all produced by the imperial court, so when I finished it, the imperial court only gave me a whole street in the middle and asked me to build a new commercial street. And if I want a house, I have to buy it in the city at my own expense.

It's still the full-price kind.

But I didn't complain, and when I learned that the city was already a city of pleasure to live in, rather than an 'industrial city' as I expected, I had the idea of giving it up.

It's just that now that I've figured out that since it's all inhabited, and even the whole city is occupied, I can also take the opportunity to try all kinds of experiments and research in this city to perfect the real layout of a city. Now that the problem of water supply and drainage has been solved, then I can be considered to have succeeded in the first step of the experiment here.

"The next step~ is to solve the power problem!"

In fact, the electricity problem is now very easy to solve. After all, the only people who can use electricity now are lighting lamps and a few devices that are only driven by electric motors. For example, pumps and the like.

The reason is very simple, although the generator has been built, the problem of voltage and power has not been completely solved. Whether it is the first batch of researchers in the academy or the current researchers, the research on circuits is only in the 'nature textbooks' of elementary schools. The main reason for the generator was to remove enough copper wires from the engines in the mall...... To put it bluntly, the principle of this generator, the people of this era have only mastered part of the theory.

Therefore, you can only use electric lights and engines that do not require voltage and current. And the voltage regulator used is still a ready-made product taken from the garage of the mall......

But even so, the matter of installing power supply in every household in White Jade City has not been solved until now.

When the White Jade City was built, the wires pulled by the entire city were the ordinary wires of the shopping mall that I used. And after actually using it, I found that even this kind of ordinary wire, under the length of too long, there will be wire loss. Even the farthest point from the power plant cannot be lit by ordinary electric lights...... Now that I think about it, I understand why there is such a building as a 'power distribution room'.

This problem is not difficult to solve, in the underground of the mall, in fact, there is a power distribution room. As long as I can find a way to remove some parts from here and take them to the academy for researchers to figure out what they do, I should be able to solve this problem.

Fortunately, both Mandarin and Duck can enter my mall at will, and they can use their abilities here to summon a hurricane to destroy the parking lot~ Ahh It's wrong, they used their abilities to summon a hurricane, dismantle all the equipment in the mall's power distribution room and take it out.

The only trouble is that this dismantling act will make me feel a kind of 'internal organ injury'. When the two of them started to dismantle the power distribution room, I felt a sharp pain in my abdomen as if I had an acute abdomen...... And I can still feel the feeling of two whirlwinds swirling in my abdomen, turning into knives from time to time to cut my intestines...... Now I understand that this mall that I have been crossing is actually in my own body! And when there was a problem in the mall and there was a crack, as soon as I touched the crack, the cause of the severe pain in my body was completely understood...... Now I'm glad I didn't make the mall a bigger problem!

After a lot of hard work, all the instruments in the entire power distribution room were finally dismantled. And I also felt the emptiness of 'being hollowed out'. It felt like someone had cut a piece out of my intestines!

When I managed to temporarily store the dismantled power distribution room in the warehouse, I myself fell into a coma in front of my eyes.

After hearing from the mandarin duck and the duck that I was in a coma for three days and consumed half the size of my body's gold, I was able to return to my normal state.

Now it seems that although the goods inside the mall can be taken out at will, many of the mall's own facilities cannot be easily disassembled! It just dismantled a small power distribution room and left me in a coma for three days. If you dismantle other facilities, you might even get your life in it! The fact that this mall is my own body has now been thoroughly proven by me......

"Now that I think about it, the fact that the 'appendix' that was cut off from Zou Congee's body can be turned into a demon tree may also be explained! It seems that Zou Congee is also an inheritor! However, when he came to his senses, he seemed to be stupid! "My thoughts began to deviate again, and now I think of what happened in the Yin-Yang School back then.

In addition, I also feel that maybe the mandarin duck and the duck, as well as Nie Xiaoqian and Xiaoyu, are also part of my body? If someone performs an operation on me, maybe they can take away the mandarin duck and the duck or Nie Xiaoqian Xiaoyu just like the appendix I cut off the Zou porridge porridge back then!

"It's just~ who is my 'appendix' among them?"

Ahem~ off topic again!

After I made a special trip to the power distribution room to the academy and let people start researching it, I realized that if this thing is to be thoroughly studied and imitated, it will not be possible to do it in a few years!

Therefore, in order to solve the power problem of Baiyu City, I had to rebuild several special steam engine power stations and a hydroelectric power station in this small city according to the original plan, so that I could supply enough electricity to the whole city with ordinary wires without the power distribution room!

This problem of supplying power to Baiyucheng is temporarily solved, but for this new city, this power supply still has some price. Because only one side of the city is next to the Wei River, I was able to build a hydroelectric power station. The other power plants in Weihe had no choice but to ignore environmental protection and began to use steam engines to burn coal to generate electricity. The power of this steam engine is far more powerful than that of a hydroelectric power station. The only regret is that the air index in this small town has obviously landslided heavily due to the successful construction of a steam-powered power station! Baiyucheng's consumption of coal has also risen significantly. But~ because of the steam engine, I thought the heating problem of Baiyu City had been solved!

The radiators have long been cast by craftsmen. The problem of pipes is also due to the invention of manual "threading machines" such as "plate teeth", and the waterproofing treatment of hemp rope that can be used as an excuse for pipes. The heating has worked perfectly.

For this reason, I also specially installed radiators for the people in Baiyucheng. This is mainly used to test whether the hot water can be heated by the steam engine of the power plant and sent to the residents without the transfer station.

"Huh! I didn't expect this to be done in one go! It seems that it is not so difficult to add a special hot water field in the city! ”

After being found out about this radiator that can be heated by himself, the entire people in Baiyu City ran to pat me on the back. If you look at it this way, the people living in Baiyu City are really enthusiastic! It turns out that they want me to do enough heavy scenes for these people this year.

I'm going to have to learn this kind of thing!

The problem with the circuit was solved for the time being, but it was after I discovered this problem that I designed a new drawing. Unfortunately, this plan would be complicated if it were someone else.

Since the solution of the circuit. By the way, it also solves the heating problem of the whole city. Then I can start the last project with a bunch of residents cheering.

My last plan was to build a heavy industrial area and a light industrial plant in another renewed city. After all, there are two things here, which are the main manifestations of the progress of science and technology in this era!
