In the study, the Ninth Princess snatched Mo Xiang's work and grinded a thick ink ink. Mo Xiang pouted her mouth and brought a pot of freshly brewed Big Leaf Tuan Tea. Shengjing is not short of tea, and it is available from all over the country. After Renault drank several kinds, he still thought that Big Leaf Tuan Tea was the most suitable for the taste.

This time, the painting was mixed with carbon pens and brushes. First of all, it was the container. Renault chose a wooden barrel, which was oversized. Zhangtan had the experience of hoop barrels. This time it was just a little bigger. It was higher than the last time and could not leak water. It also had to add a mechanism. The bottom of the barrel was left with a water outlet to connect to the pipe.

When choosing wood instead of iron, the problem of processing difficulty and rust is considered. In fact, the service life of wooden barrels is not long, and it is extremely different from that of iron barrels. Over time, even if they are not broken, they will be covered with scale.

The water pipe is a bit difficult. After asking Zhang Tan, the answer he gave was that the pottery pipe, bamboo pipe, and wooden pipe had their own advantages and disadvantages. It is hard to say which one is better, at least it can be used.

Renault first discharges the wooden pipes, temporarily uses bamboo pipes, waits for Cui Qing to get the fire kiln, and fire a batch of ceramic pipes or porcelain pipes.

Then there was the copper pipe, just hand it over to Zhang Tan, he did this. Zhang Tan didn't understand why the copper pipe was very thin and had to be plated. Renault didn't say it, and he didn't dare to ask.

Next is the shower head, which is called on the earth. Renault didn't expect to create such a fine thing. Who would have thought that Zhang Tan asked a few questions and said confidently that this is fine.

In fact, the difficulty of showerhead is not high. The real difficulty lies in the interface, which has extremely high requirements for size, as well as issues such as sealing and durability.

Zhang Tan patted his chest and promised that he would give it to him, so that he would not leak a drop of water.

Except for the big bucket, the rest are all small items. Zhangtan is not alone, but a whole family, with several sons and apprentices, and they have learned craftsmanship from him since childhood.

First, distribute the things, who can do what and what the requirements are, Zhang Tan explains one by one, and sends the work, he only serves as interfaces and copper pipes.

Huya was not idle either. He directed the Heifeng people to work outside the bathroom, building a high platform against the wall, which was prepared for the bucket.

Then there was the floor in the room. There was no cement, so he could only use it. I'll talk about it later. Renault had already thought about it. The cement had to wait. He knew it was burned, but he really didn't know how it was burned.

Let’s study porcelain first. As long as you can burn out porcelain, burn the floor tiles and use them, and wait for the cement to burn out, you can truly get the bathroom. Now everything is simple and you can use it.

The ground needs to be cleaned and water needs to be dug. Don’t worry about this. The wealthy families in Dachu have long had sewer pipes and used ceramic pipes. Small doors and small households are not so luxurious. They just use basins to pour them into the gutter outside.

The stove was built in the outer room, and many iron rods were installed in the stove and inserted into the stove wall.

Until it was dark and finally ready, Renault kept sighing that it was too luxurious, so he moved his mouth and had no idle people in the family. Dozens of people forced to use one day to turn his ideas into reality.

The bamboo pipe is connected to the wooden barrel and enters from the roof to the outer room. The copper pipe is plated and placed in the stove. The bamboo pipe and the copper pipe are connected together, and the other end of the copper pipe is connected to the shower.

Finally, Renault realized why Zhang Tan dared to say that it was impossible to leak water. It turned out that Da Chu had fish glue, which was a good thing, and fish glue was a stamina. Fortunately, Da Chu did not lack warriors, and there were many people with great strength.

Fish glue, double-known fish bladder glue, is processed with fish bladder. It is a very useful natural animal glue. It was originally used to make crossbows and is difficult to buy outside. With Renault's name, you don't need to buy it at all. You can just go to the Ministry of Works to ask for it.

Zhang Tan climbed up and down, checked several times before he felt relieved. The things were all done by others, and he only vaguely understood the use of this thing.

With a command, a fire was generated in the stove and the water was supplied to the bucket. After a while, the shower made of brass flowed out of the water.

After waiting for a while, the water flowing out of the shower was steaming, and Huya was stunned. What's going on? Why is it hot water?

Cui Qing came back before dark and was busy with everything. At this moment, Cui Qing, Princess Ninth, and Zhang Tan all figured it out.

The whole set of devices is not complicated, and the reason is very simple. As the water flows to the lower level, the water from the wooden barrel flows through the copper tube. The copper tube and water are heated and then flows out of the shower, so it is naturally hot water.

"Sir, Cui Qing has something unknown?" Cui Qing asked tentatively. He was just an apprentice. The secret master would tell you in a good mood, and he would not let you see it when he was in a bad mood. So he was extremely careful when asking for advice.

"Speak straight." Renault was in a good mood. He tried it after a while and finally took a shower. In fact, it was a little more troublesome to take a bath. With a bathtub, Mo Xiang and Chu Rui always wanted to help him wipe his back. Renault was not very used to this and never agreed.

"Sir, this water flows down from the wooden barrel at a high place. Cui Qing understands that after heating by the copper tube, Cui Qing also understands that when it reaches the low place, why does the water flow to the high place again?" Cui Qing asked as he pointed out from the stove and from the shower.

Yoho, it's so smart. Renault found that he underestimated the people of Da Chu a little.

Nodded slightly, trying to grasp the style of a university professor: "No, if you ask well, you can learn something if you are willing to use your brain."

Speaking of this, I pondered for three seconds and reflected on whether my behavior was right just now. I felt something was wrong. It seemed that I was too young and was not suitable for this model, so I had to change it.

"Since you know that water flows to the lower part, then do you think the shower is high or low?" Renault asked, pointing to the steaming shower, and at the same time he felt as if he had done something wrong.

Cui Qing thought something and hadn't thought it through.

The Ninth Princess's eyes lit up: "Sir, the shower is higher than the copper tube and lower than the wooden barrel."

Yoho, another smart person, so awesome.

"Smart, you have to remember one truth: water flows from a high place to a low place. The highest point is the key. Anything below the highest point is the low place." Renault said that this passage was always difficult. The three people in front of him were smart people in Dachu, but after all, they had never learned it systematically. They directly talked to them about the principle of the communicator, for fear that they would not understand it.

Zhang Tan suddenly realized that he was the last one to understand. The craftsman was just good at craftsmanship and received much worse education, far less than Cui Qing and Princess Jiu.

When he was built before, he was surprised and always felt that he hadn't figured it out, and now he finally understood it all.

After teaching the principle of the communicator, Renault turned his back and went back to sleep, but he stopped washing it today. The three of them figured it out, and Renault also figured it out, and today's invention was screwed up again.

"I'll try it." Renault left, Huya rushed in with excitement on his face. It was very interesting to take a bath like this.

Take off your clothes and close the door.

‘Ao…’

In less than ten breaths, I could hear the sound of the tiger teeth and the roar of half of the Divine Works Hall.

Nothing, hot!

Renault designed a simple gas water heater, which was designed with a congenital deficit. It was made of a single water pipe, and the stove was heated, so it was impossible to adjust the temperature.

When he saw the heat coming out of the showerhead, he felt something was wrong. After looking back, he knew what was wrong. The single water pipe came out with hot water, and it was not temperature-controlled. It all depends on burning firewood and cannot be added to adjust it. Whoever uses it will know, and the consequences will be borne by yourself.

It’s such a god. Why is it so difficult to invent something practical? A simple firewood water heater is like this. Renault takes the lead, because he is afraid of embarrassing. Such a water heater is just right to remove the hair of a pig, so just take a shower.

Renault suffered from insomnia until the second half of the night, and fell asleep in self-blame.

When I got up the next day, it was almost noon. Mo Xiang and Huya were not outside the room. Gong Churui brought him a wash water and waited for him to clean up.

"Where is Huya and Mo Xiang?" Renault asked.

"Go to see the Secret Master."

"Hmm? Bai Jing, are you here, seniors, Fire?" Renault was shocked. Didn't you visit the dock the day before yesterday? What are you here to do today?

"Why didn't you call me?" This is a very rude thing. During this time in Da Chu, what Renault is most unsuitable for is etiquette. The people of Da Chu have too many etiquettes, which makes people feel uncomfortable.

"You two priests will not let you call you, saying that you have been busy for a day and are exhausted, so you need to have a good rest."

This is not possible, and I won’t eat anymore. I let Chu Rui lead the way in front. The two seniors came to the door and didn’t go out to greet him. I still slept until now, and Renault felt that it was too much.

Renault always thought that he was going to take the secret master route, and these two were his great backers, and Emperor Chu had to be in the back row. No one had to be polite. These two people came and had to be entertained.

The more I walked, the more I was getting worse, it wasn't the front yard study room, so why did I come to the back yard bathroom?

Baijing, flames, were in the bathroom now. They had climbed up and down several times, and kept burning the stove, heating the copper pipes, and adding three times to the big bucket of water.

Seeing Renault, Bai Jing patted his shoulder: "No, an interesting little thing, implies the truth, you can afford this name of divine work."

Fire turned his head and looked at him, but didn't say anything. Renault saw a trace of dissatisfaction in his eyes, and seemed to not like the shower.

Bai Jing saw it and laughed: "Don't pay attention to him. Brother Huo believes that although this thing is wonderful, it is only suitable for rich people, and it is of no use to the people."

Renault hurriedly bowed and said, "It's a lesson." Flame is right. Although this thing is simple, it can't take much material. But the big wooden barrels, copper pipes, and copper showers are not affordable for ordinary people. This is not the manual money for making it.

"Today, we two will give you a secret pillar. After listening to your longing, we will naturally have to look at it. Not to mention that, things are average and there are many mistakes and a little correction is also practical. The best thing is that it implies the truth." Bai Jing said, pointing to the wooden barrel outside, then the copper tube at the lower level, and finally pointing to the shower.

The so-called ultimate truth is the principle of the communicator. Cui Qing felt it vaguely. Baijing and fire fell in love with half an hour and realized it by himself.

Originally, it was a secret pillar, which meant to visit. Old Master Bai Jing was very helpful and moved quickly enough. Even if the secret pillar was erected, even if the Shengong Hall was famous, it would be much more convenient for Cui Qing and Huya to go out to do business in the future. It would be legitimate.
