The ancients used a simple and effective way to clean up their buttocks after being drenched.

In each store, a few bamboo slices are reserved. After finishing, use the bamboo slices to scrape the dirty places a few times, and it will be finished.

My dear mother, this is a bamboo piece. It took Chen Feng a month to be considered as following the local customs.

There are also high-end things, that is, using paper.

It was not until the Mongols occupied the Central Plains that it became popular, and this was only achieved by rich families.

After enduring for a few months, Chen Feng finally had the ability to use paper. At this time, his anus had been trained to be extremely hard.

In this era, the reason why paper does not use paper to clean her buttocks is because paper is too expensive. For ordinary people, paper is a very luxurious thing. Even when Yue Fei was young, his mother taught him to read on the sand.

So, using paper to clean is a waste.

Whether it is a high-ranking official or a low-level person, they did not expect that there is a simple and effective way to clean the buttocks: wash it with water!

This method is very common in the Arab world.

Even in later generations, when you stay in the most luxurious hotel in the Arab world, the bathrooms inside are luxurious and luxurious, you can’t find toilet paper.

What should I do? Every Arab has developed the habit of using his left hand to pick up water after the poop, so they don’t use their left hand to clean it after shook hands and had a meal.

Of course, with the advancement of technology, there is no longer a need to use the left hand to do this kind of work. An advanced toilet can replace the function of the left hand. This is a high-end thing in later generations, called a smart toilet.

Although it was sold at a high price, the main function of a smart toilet is that after the work is done, several streams of water will be sprayed out to clean it with water. The rest of the functions are all bluffs.

Chen Feng's toilet also has this effect.

When Chen Feng heard that this toilet did not use bamboo sheets or toilet paper, Shen Fu became interested.

After all, Shen Fu is still a person in his forties and sometimes he will have some childlike innocence.

"Mr. Chen, you don't need toilet paper, how to clean it?" Shen Fu asked.

"You can tell when you sit down." Chen Feng said.

Shen Furao sat on with interest, and it was very comfortable to sit down.

"Brother Zhongrong, don't you need to take off your pants when you are giving up?" Chen Feng said with a smile.

"This..." Shen Fu hesitated for a moment, took off his pants in front of Chen Feng, feeling a little embarrassed.

"Brother Zhongrong, since you come here, you will be at ease." Chen Feng said.

Shen Fu was determined to take off his underwear and sit on it.

When I sat down, I felt very comfortable. The washer softly wrapped around the fat outside my buttocks, revealing the middle again, which was both convenient and practical.

"Brother Zhongrong, are you ready?" Chen Feng asked.

"What? You're ready." Shen Fu didn't know what Chen Feng meant.

After hearing Shen Fu's answer, Chen Feng turned on another switch.

Suddenly, Shen Fu felt that the following streams were squirting out, flying towards his chrysanthemum position.

He wanted to stand up when he was shocked. At this moment, Chen Feng pressed a palm on his shoulder just right: "Brother Zhongrong, are you comfortable?"

"Comfort...comfortable." After the initial shock moment passed, Shen Fu felt the right water for hot and cold water gushing to that position, like drizzle, driving the whole body from that position, it was very comfortable.

Shen Fu was enjoying all this, and at the same time, he was thinking rapidly in his mind that the things he saw today also had a great future and these things would definitely be very popular.

After the water was sprayed, his butt was still wet. At this moment, Shen Fu felt a hot stream spraying again, and the water stains were quickly dried.

I need one at home for something I enjoy like this! After standing up, this was the first thought in Shen Fu's mind.

Looking at Shen Fu's expression, Chen Feng knew that this guy was moved. This flushing toilet was simple to solve the problem of flushing, and solving the problem of intelligence, that is, the problem of not using toilet paper, made Chen Feng's mind a little.

Finally, Chen Feng decided to make this intelligence artificial intelligence, that is, people who operate it. In the room connected to this toilet, there is a small kitchen, which is used to burn water and heat air.

When washing the butt, you need water that is suitable for hot and cold. This is burned by people and then sent to the toilet through bamboo tubes. The subsequent heat flow is directly bulging in after heating the air. Everything is carried out according to Chen Feng's command.

Even so, this thing is a brand new invention. In this world, advanced concepts are the most important.

The kiln factory took a lot of effort to burn such an irregular shape. Liu Sier burned more than 20 according to the drawings drawn by Chen Feng, and only this one satisfies his requirements.

Chen Feng knew that luxury was endless. Floor tiles and wall tiles were arranged in this bathroom, and if the toilet was packaged and sold, it would have to be sold at least 200 taels of silver even if it was installed.

Moreover, he is very confident that this thing will soon enter the rich family. These people are not short of money, but they are pursuing high-end and enjoyment.

"Mr. Chen, how much does this set of flush toilet cost? Can you put one for me in Pingjiang's home?" The first sentence Shen Fu said after lifting his pants, which confirmed the market value of this kind of thing.

"Brother Zhongrong, if you need it, I can give you a set." Chen Feng said: "But, Brother Zhongrong, are you just caring about your own enjoyment?"

After hearing Chen Feng's question, Shen Fu suddenly thought of something: "Mr. Chen, if you can leave these for sale, you will soon enter various courtyards."

"Our Chen family can expand the business in the Central Plains by itself." Chen Feng said: "All overseas businesses can be left to Brother Zhongrong to expand."

Shen Fu was overjoyed. He could tell at a glance that this thing was much more profitable than floor tiles.

"Thank you, Lord Chen. If possible, I hope you can get a batch of such goods before the New Year, along with floor tiles, and ship them overseas." Shen Fu said.

Unexpectedly, after saying this, Chen Feng did not answer, but just looked at him.

Shen Fu suddenly thought of the conversation upstairs just now.

"Of course, if the Chen family needs it this time, they can go to Southeast Asia to experience it. However, this exchange may be risky and you need to be prepared." Shen Fu said.

"We are ready." Chen Feng said.

Using these things in exchange to make Shen Fu agree to take the Chen family to Nanyang to do business. Even if this preliminary preparation is completed, I just don’t know if the indigenous people in Nanyang will be interested in this flush toilet?

Those natives can solve the problem by digging a hole. However, even if Chen Wansan's sales methods are just normal people, he can sell his crutches.

In Chen Feng's consideration, this kind of thing is not suitable to be sold in Southeast Asia. If it is sold in Europe, it will be the most promising.

Since the Chen family has decided to go into the sea, the South Ocean is the sea, and Europe is also the sea, but Europe is full of civilized people.

Flush toilets, floor tiles, wall tiles, cement, these things are all small things. Chen Feng now has a new product that is about to be released.

Liu Sier's potential was discovered to the greatest extent by Chen Feng.

If firing a kang tabletop at the beginning was just an impromptu thing by Liu Sier, then firing cement was the result of repeated attempts, which was a challenge to Liu Sier.

Liu Sier succeeded and tried it hundreds of times, fiddling out the task of cement assigned by Chen Feng. With this thing, wall tiles similar to floor tiles can be placed on the wall. Moreover, if you use it to build a house, it will be a hundred times stronger.

If the walls of Xuzhou City were built with this cement, the power of the Huihui cannon would be greatly reduced.

As for this flush toilet, it is just a strange shape. In essence, it is still a porcelain piece.

The benefactor was obviously not satisfied. When the porcelain stone powder was transported in large quantities, they could make it on a large scale. At this moment, a new thing was also brought up by the benefactor.

It is as transparent as crystal, and it must be made into large flat plates. What is the name given to it by the benefactor?

Just like when he made cement, his benefactor only gave the formula, quartz sand, alkali, and limestone.

Quartz is a necessary raw material when firing porcelain glazing, and alkali can be obtained in wood ash. As for limestone, this powder, they no longer need to waste their energy.

Liu Sier himself needs to study and ponder how these raw materials are compared and how they are fired.

Chen Feng just reminded him one of the things that after burning it into water, someone needs to hold a stick and stir it constantly.

Stir the glass water!

In later generations, many time travel novels mentioned making glass, which is why Chen Feng was able to recall these recipes.

However, they all missed one of the important steps, which was stirring.

Glass appeared in Europe more than three thousand years ago, and began to be used in doors and windows in the fourth century AD. By the seventeenth century, glass became an ordinary item.

Unfortunately, they could not solve a problem at that time, and there would be bubbles in the glass, which was also the most obvious sign that distinguished glass from crystal.

This bubble, when used on windows, only affects some aesthetics. However, in other aspects, such as on telescopes, the presence of bubbles will seriously affect the use.

This bubble bothered many people until the war was resolved by the islanders.

The solution is very simple, which is to stir and stir the air in the liquid. In order to obtain this technology, countries have sacrificed many spies. When the answer to the mystery is revealed, they all feel like they are about to vomit blood.

Fortunately, Chen Feng knew about this process, so he told Liu Sier from the beginning that of course, it would probably take one month, one year, or even ten years to truly burn qualified glass.
Chapter completed!
