For a liberal arts student, it is too difficult to climb the science and technology tree.

Xu Yuanzuo, based on the only scientific and technological knowledge he has, can only come to the conclusion that he walks on two legs: materials and technology.

All of this is based on a large amount of capital investment. As a businessman, if the input and output are not proportional, you will never be willing to spend this unjust money.

The reason why the steam engine was born in Britain was precisely because of their abundant coal and iron ore deposits, and the mines were generally waterlogged, and they needed new kinetic energy pumps. This led to the invention and development of the steam engine, and for a short time it was only used to pump water from mines. Once it was placed on the rails, it was discovered that the steam locomotive was not as fast as the horse-drawn carriage, and rightly laughed.

Xu Yuanzuo has ambitions far beyond those of businessmen, but he is also quite timid about high costs. If you understand the process and materials, you can roughly estimate the silver taels to be burned, but you don't understand anything, and the researchers don't understand anything, then scientific and technological research and development will become a bottomless black hole.

After Xu Yuanzuo returned home, he finally decided: it is better to do what he can do first.

For example, building roads.

Under the guidance of Xu Yuanzuo, Lao Yan of the construction club successfully built a hardened road. From the roadbed to the road surface, anyway, there are all the terms in the books, and as for the actual effect, it can only be said that there is still a lot of room for improvement. Judging from the road surface alone, it is still very shocking to walk on it, no dust on sunny days, no mud splashing on rainy days, and rainwater can flow into the river along the culverts on both sides and will not accumulate on the road.

As for the carrying capacity, Xu Yuanzuo really can't estimate it. Because it is built in the middle of the street, there are not many horse-drawn carriages, so the impact of heavy-duty horse-drawn carriages on the road surface has not been seen at present. Xu Yuanzuo would not deliberately go out of his way to do some destructive experiments in order to find an answer—he didn't have enough money yet.

Because of the limitations of silver, Xu Yuanzuo or the Guangji Association should be asked to undertake the task of building roads. Apparently impossible. Xu Yuanzuo wanted to promote the four-wheeled carriage, which was obviously more comfortable than the sedan chair, in order to promote the road construction needs of the wealthy. However, the number of horses in the south of the Yangtze River and the crisscrossing waterways have become obstacles.

Xu Yuanzuo leaned on the Taishi chair, tilted his head, and saw that a lot of dust had accumulated on the roof beams - it was time to find a time to finish hanging the ceiling.

Qi Miao cautiously shouted outside: "Brother Zuo, Kang Xianggong is here." Also with guests. ”

Xu Yuanzuo sat up, not surprised by Kang Pengzu's visit, and said, "The main hall is entertained, and I will come when I change my clothes." He didn't know who Kang Pengzu had brought, so it was better to be solemn.

The relationship between Kang Pengzu and Xu Yuanzuo is naturally not ordinary, but this time he is a little embarrassed. Because he has a wide range of friends, he is a righteous and squandering money, and he will talk nonsense when he drinks too much. This time, it was because of drunken gaffes that he promised some inappropriate words to people. Today was forced to cash in.

Xu Yuanzuo came out after changing his clothes, and saw Kang Pengzu bring three people dressed as students. It's just because he doesn't go to school very often, and he's a freshman.

Kang Pengzu introduced them one by one, and everyone made a move, and then the guests of honor were seated. Xu Yuanzuo served good tea and was thinking about finding something to talk about, but Kang Pengzu said straight to the point: "Jinglian." Can I borrow a toilet at the house to change clothes? ”

Xu Yuanzuo was stunned for a moment, and was completely convinced: You can hold back for a long time to finish those virtual processes. The kidneys are strong!

"Brother Changsheng, why bother to see outside! Chess is wonderful, and quick to lead the way. Xu Yuanzuo almost wanted to say: Don't suffocate.

The nervous expression on Kang Pengzu's face suddenly relaxed, and he beckoned, "You can come with you." ”

The muscles on Xu Yuanzuo's face stiffened: How old is it? Do you want to go to the toilet in a group?

The other three people actually got up one after another and thanked Xu Yuanzuo: "Disturb and disturb." ”

Xu Yuanzuo watched the four people walk out and blurted out, "You guys are actually here to visit, right?" ”

Everyone turned their heads hehahaha, quite embarrassed.

Kang Pengzu is finally an acquaintance. He turned around and said: "Jing Lian, I heard that the convenience office in the house is outstanding and eye-opening, and I thought that hearing is not as good as seeing, so I wanted to come and see." ”

Xu Yuanzuo built toilets at any cost. Although there is also an emotional factor, the main thing is hygiene and practicality. I heard that Kang Pengzu and others just wanted to see the legendary bathroom, of course they would not be stingy. He smiled and said, "In that case, come with my little brother." Originally, he just wanted Qi Miao to take them to the common bathroom in the backyard - for the slaves. But since they are going to visit the eye-opening, of course, it is more appropriate to bring it to the bathroom in their own courtyard.

Because his parents did not forget their true colors, they couldn't stand Xu Yuanzuo's extravagance, so the most "advanced" bathroom facilities in the house were in Xu Yuanzuo's yard.

At that time, there was only one bungalow in the small courtyard, which was divided into a master bedroom and a study. Now Xu Yuanzuo has been rebuilt several times, and a two-story small building has been built on the location of the original bungalow, the ground floor is the inner guest hall for receiving relatives and acquaintances, and the second floor is Xu Yuanzuo's bedroom and chess's small room, bathroom, and utility room. Another bungalow was set up in the courtyard, which was divided into a study and a storage room.

Kang Pengzu and the three little friends he brought were all rich and noble, looking at the courtyard and house, he also felt that the famous little God of Wealth was really a little too poor. After Xu Yuanzuo went upstairs, he found that the entire building was spotless, and there was a faint fragrance of flowers, but he couldn't see the flower arrangement, and the poverty became elegant.

"This is it." Xu Yuanzuo pushed open the door of the bathroom, took a step in first, and moved out of the way.

Kang Pengzu was the first to follow, and he couldn't move his steps in an instant. He realized the strangeness under his feet, lifted it slightly, spun it down again, and said to Xu Yuanzuo worriedly: "This is...... Porcelain? ”

Xu Yuanzuo looked at Kang Pengzu's tiptoeing appearance and was quite amused, and said, "I call it a tile." Of course, only one side is glazed. ”

Kang Pengzu looked around the bathroom that had been completely "built" with tiles, cautiously walked to the window, and immediately found the blue and white glazed red washbasin and the pure white porcelain toilet. He lifted the toilet lid of the camphor wood and found that there was a layer of gasket inside, which looked quite thick, but it was hollow when he lifted it.

"When you drown, you can pour hot water into this gasket, which will not feel cold and clean." Xu Yuanzuo explained. He couldn't make an electrically heated gasket, but it was still easy to make a gasket that was heated by hot water manually. The extra trouble was not his, and he couldn't even do it - it was the work of an inferior servant.

Kang Pengzu was amazed, if he didn't know that this was a commode. I can't wait to touch it with my hand. He said: "This porcelain is also good porcelain!" ”

Xu Yuanzuo chuckled: "This is burned in the kiln factory at home, it's nothing." He tried bone china when he burned the toilet, and it will become the fist product of his own kiln in the future. As he spoke, he pulled off the brass handle of the toilet tank.

Clean water rushed diagonally out of the inner wall of the toilet, whirlpooled, and flushed into the sewer.

The four of them let out a low exclamation in unison.

"It's so quick to flush out. It won't stink. Xu Yuanzuo said: "The filth that washes down will accumulate in the septic tank and produce biogas. Biogas can be lit, so I set up a lamppost at the back door, which is the lit biogas. It is not yet dawn when the next person enters and exits in the early morning, which can be more convenient. ”

Everyone was amazed again, and even praised Xu Jinglian's clever use of this thought.

Another person paid attention to the washstand, looked at the swimming fish under the porcelain basin, and exclaimed: "This blue and purple is also made by Brother Jing Lian himself?" ”

The kiln factory that Xu Yuanzuo bought can fire large vessels, which is already very remarkable in Songjiang. However, because of the problems of materials and processes. Blue and white porcelain is obviously inferior to Jingdezhen's products - so Xu Yuanzuocai found a unique way to take the bone china production route. He said: "This glaze red was purchased in Jingdezhen, and it is said that it is also the craftsmanship of a master craftsman. ”

The man obviously knew something about porcelain, caressed the rim of the basin, and said in a loud voice: "I can see it, I can see it." ”

Another person asked, "This carp mouth can spit out water?" ”

Xu Yuanzuo unscrewed the copper wheel on the right side, and the carp mouth on the basin really spit out a stream of water. The water pressure is not large, but it is unprecedented.

Kang Pengzu saw that the pipe behind the carp had sunk into the wall. I couldn't help but ask, "Where does this water come from?" ”

"Naturally, it's from heaven." Xu Yuanzuo made a joke: "I built a water tower on the roof to collect rainwater on rainy days." On weekdays, every three or five days, let the slave add water again, and the energy will continue to release clean water. "In this era, rainwater is a non-polluting source of water, and it is more reassuring than river water.

"And what is the use of this copper wheel on the left?" Kang Pengzu asked again.

Xu Yuanzuo stroked his palm and smiled: "This really took a lot of brain power for the little brother!" Brother Chang Sheng didn't give it a try. ”

Ancestor Kang Peng turned off the cold water, and then carefully turned the copper wheel, and the same fish actually spat out a stream of hot water from its mouth, and the heat was emitted.

"What is the reason?" And all the people were amazed.

Xu Yuanzuo laughed, and led them to the utility room next door to see: it turned out to be a copper pipe that was drawn out separately. It leads to a one-foot-high, three-foot-thick copper tank. The water tank was framed by an iron shelf, and there was a stove under it, which was sealed and did not burn vigorously. It's just that the hot water in the tank is kept between forty and fifty degrees. There is also a lid on the tank, which allows water to be added directly and also makes it easy for steam to escape.

"This is the trouble because you have to have someone to take care of you from time to time." Xu Yuanzuo said.

Everyone shook their heads again and again, and said, "It's so subtle, even if you send someone to watch it, it's worth it." Another of them said: "I am most annoyed by people dangling in front of my eyes, if there is such a ...... The bathroom is exactly what I wanted. Not to mention sending one person to watch, I'm happy to send three or five more people. ”

Xu Yuanzuo was also overjoyed when he heard it: It seems that this market can be developed!

Everyone returned to the bathroom, and Kang Pengzu opened a bamboo curtain, revealing the white porcelain bathtub inside.

Xu Yuanzuo was a little embarrassed: "This is no different from our ordinary bath bucket, I just made it a little bigger, you can lie down." ”

"Can't put your own water?" Kang Pengzu did not find the mouth of the fish, but he saw the copper plug below.

"It is up to the servants to burn it and pour it in." Xu Yuanzuo said: "My next step is to think about how to solve this problem and let the hot water come in directly." "The water tank in the utility room alone can't make hot water for bathing.

"It's nice to be able to release water." Someone unscrewed the copper plug, and it was clear that it was used to drain water.

Kang Pengzu knocked on the tiles on the wall again and said, "This is really a person who is not allowed to look good. Only from the outside, the little God of Wealth in the clouds is an extremely simple person, but on the inside, it is so luxurious. These blue and white porcelains were also bought in Jingdezhen? ”

Xu Yuanzuo said with a smile: "This was burned by the Han family themselves." ”

Everyone laughed and said: "In the future, you are not allowed to be humbled by the 'Han family', it is too embarrassing for others." ”

Kang Pengzu looked up and down, and he was also very puzzled by Xu Yuanzuo's wooden ceiling. Xu Yuanzuo said: "Thermal insulation. People feel more and more that they have lived in "poverty" all these years.

"Jing Lian, how much money did you spend on this whole set?" Kang Pengzu couldn't help but ask.

Of course, Xu Yuanzuo's heart was bright, but he waved his hand and said, "Who is patient to worry about these things?" I contracted it all to the construction agency. The whole yard was built and built, including the tiling and these bathrooms and toilets, but only a thousand taels of silver. ”

"One thousand taels!" Everyone took a deep breath.

Xu Yuanzuo knew that the number was a little scary, but said: "Do your own calculations, how many times do you have to go to the Qinglou Chu Pavilion in a year?" How much money will it cost to go in? This is a daily use at home, and once it is purchased, there is no need to replace it. Furthermore, the most troublesome part of a family's feng shui is here, to be odorless and filthy, the family business can prosper, and all diseases will not be born, how much is a thousand taels? ”

Kang Pengzu is a person who throws three or five thousand taels of silver at will, when he bought a jade Linglong for three thousand taels and gave it away, he didn't even blink his eyes, and immediately disdained these three "sours", and said: "Jing Lian doesn't need to pay attention to them." The man at the wooden cabinet is asking you to call for me. and the bathtub and toilet burned by your kiln, I want six sets each...... By the way, who did you buy this glazed red basin from? I'm going to have six too! ”

Xu Yuanzuo immediately called Qi Miao and ordered him to copy the addresses of all the contacts to Kang Pengzu's long-term entourage. On a whim, they were invited to visit the public baths and toilets. Because it is for the next person, it is simple because it is ugly, and there are no tiles, it is all chalk, just like the public bathroom outside, but the shower is used, which shows something different.

The students all feel that this is acceptable, even if they can't meet Xu Yuanzuo's enjoyment standard as soon as they come up, it's still no problem to repair a slave's bathroom and toilet at home. Whether it was for one's own use or for the slaves was another matter.

Xu Yuanzuo led everyone back to the hall and said, "Little brother, I have done some experiments recently. It's funny to say, at the beginning, I just wanted to know why 'rotten grass is fireflies', but in the end, I found out that the sages' so-called 'rotten grass is fireflies' is a big fallacy! ”

Everyone's ears pricked up, and they secretly said in their hearts: I know that you are a descendant of the heart, so it may be inappropriate to accuse the sons of the sages like this!

Xu Yuanzuo said the comparative experiment he designed in his mind as a real thing, mainly to prove that whether it is fireflies or maggots, they are not born of rotten grass and carrion, but hatched from insect eggs. This brings the conversation to the microscopic level, which is the invisible "bacteria".

Judging from the disgusting expressions of the people, the bacterial theory that appeared for the first time in the world had a good response.
