The old Taoist took the Arabic numerals home yesterday and spent the whole day bored in his study. The more he thought about it, the more magical it became.
Bringing it into the calculation of astronomical calendars, it is indeed twice the result with half the effort. In the past, calculation formulas that required a lot of calculations can now be easily solved.
Looking back at the drawing of the fire bed drawn by Fang Jun, the more he looked at it, the more it made sense. Although he did not understand the flow of air and the role of air pressure, the simplicity of it did not prevent him from understanding the mystery.
My heart became more and more alarmed and uncertain. There was a widespread rumor among the public that this Fang Erlang was uneducated, dull and straightforward. However, I could not tell from his face that this person was an ignorant and vulgar person. Moreover, the Arabic numerals seemed simple, but in fact they were very mysterious.
, it is difficult for ordinary people to understand the twists and turns, but Fang Jun picked it up easily...
Not only is the second son not as useless as outside rumors, it is not an exaggeration to say that he has "a beautiful belly"!
What interests Li Chunfeng the most is: How can a person have the roots of short life and bad luck at the same time, and these two completely different appearances in people with long fortunes and prosperity?
Li Chunfeng is good at the number of strange sects, and face recognition is not his strong point. It seems that he needs to ask Uncle Yuan for advice...
Immediately, Li Chunfeng wrote a letter and sent it to Yuan Tiangang who was traveling in Shu. He visited again and asked Li Chunfeng for advice on the secrets of Arabic numerals.
However, when they arrived at Fangjiazhuangzi, they learned that Fang Jun had gone into seclusion and did not see outsiders.
Li Chunfeng was stunned. He couldn't laugh or cry at Fang Jun's statement about "retreating". This guy is neither a monk nor a Taoist. He neither practices Buddhism nor immortality. What kind of retreat is he doing? He clearly knew that he would come, and it was just an excuse.
But have you ever offended someone inadvertently?
After thinking about it for a while, I couldn't think of a reason, so I had to go back with a frustrated sigh.
Fang Jun did run to the blacksmith shop in the back mountain to avoid Li Chunfeng at first, but after only one day, he couldn't stay any longer.
The reason is that craftsmen actually made flat glass...
Looking at the uneven and twisted flat glass, Fang Jun was very excited.
Although these glasses cannot be used as window glass, they are enough for building greenhouses!
Just think about how even a prime minister's house like the Fang family could not see a few green vegetable leaves throughout the winter, and you will know how rare off-season vegetables are in this era.
Every time you cook mutton, the most expensive thing is not the pieces of moderately fat and lean mutton, but the few green vegetables...
In fact, the Tang Dynasty already had greenhouse vegetable cultivation technology, but due to the high cost, there were only a few greenhouses in the royal inner courtyard that relied on fire to heat up vegetables, and there were no materials with good light transmittance and heat insulation.
The production was extremely low and it did not spread.
Therefore, when Fang Jun summoned craftsmen to build a greenhouse, he met with unanimous opposition.
Fang Quan cried with an old face that looked like a chrysanthemum, and advised earnestly: "Erlang, don't make trouble. Someone once heard that this greenhouse requires a huge fire pit on which to plant all the vegetables.
It is also necessary to build a house to block the cold air, which is expensive. The key is that the technology of making a fire is too difficult. It must use good bamboo charcoal. If it is ordinary firewood, the temperature cannot be accurately controlled. The vegetables will either freeze to death when it is cold, or they will heat up.
It’s all done...Besides, this glass is too precious, so wouldn’t it be in vain to use it to build a greenhouse?”
He was still thinking about the prism that had been sold for 40,000 guan, and he subconsciously thought that so much glass shouldn't be sold for 18 million guan?
But Fang Jun didn't care: "Jin Gui is an egg. It's made of sand. It's not like you don't know... I'm warning you one last time. From now on, no one is allowed to make even one of those prisms. Otherwise, the family law will serve you."
,Understand?"
Just kidding, if word spreads that the "artifact that can summon rainbows" is the same as these broken glass, it will spoil the dish. The Du family is fine, even if they know that they have been tricked, there is nothing they can do, but if His Majesty Li Er gets angry, he can
Have your own good?
Everyone also knew that this matter should never be mentioned again, and they all nodded in agreement and swore and swore.
Fang Quan wanted to persuade him again, but Fang Jun stopped him and said, "Uncle Quan, I asked you to come here. I'm not asking you whether to build this greenhouse, but how it should be built. Let me share your thoughts."
No matter what you do, authority is the most important. Even if you know that you are doing it for my own good, you will never allow yourself to contradict yourself in front of so many people.
Authority represents the right to speak. If Zhuangzi wants to develop and grow according to his own vision and become a solid foundation for himself and even the entire Fang family to live a happy life in the future, he can only have his own voice.
If you say it yourself, you must do it, no doubt about it.
Otherwise, every decision you make is a concept that is more than a thousand years ahead of the times. How can these people understand it?
Just talk and argue, don’t do anything...
When Fang Quan heard this, he felt a little unnatural.
He is an old man of the Fang family, and since everyone in the Fang family has always treated each other with courtesy, he maintains his seniority and always speaks the truth in this village.
But Fang Jun's words awakened him. After all, there is a distinction between superiority and inferiority. There is order at the top and bottom. Questioning the master again and again is not the way of a servant.
Moreover, Erlang has used a series of deeds to prove that his vision and ability far exceed his own...
Fang Quan felt relieved. Since he couldn't stop it, he would give some advice.
"I heard that the royal greenhouses in Lishan Villa are irrigated by hot spring water?"
He was asking Liu Laoshi, the carpenter in Zhuangzi.
This old man is not very skilled in craftsmanship. I remember that last summer the Construction Department of the Ministry of Industry came to Zhuangzi to recruit him to help repair the Royal Villa on Lishan Mountain. I thought he would be more familiar with it.
Sure enough, Liu Laoshi nodded and said: "It's true. I heard that the hot spring water is brought in in winter and placed in an open-air pool first. When the temperature drops to the required temperature, it is introduced into a greenhouse for irrigation."
Fang Quan then said to Fang Jun: "We also have a hot spring in Zhuangzi, why not build a greenhouse there?"
Fang Jun asked curiously: "We also have hot springs in our village?"
Liu Laoshi smiled and said: "Not only is there one, but there is more than one place. On this Li Mountain, there is no hot spring emerging from any mountain col. There are so many hot springs."
Fang Jun was overjoyed: "Take me to see it quickly."
At that moment, several craftsmen led Fang Jun out of the blacksmith shop and walked a short distance along the mountain road when they found a small pool at the foot of a sunny hillside.
In the twelfth lunar month of winter, the wind is biting.
The small pool was filled with rippling water and mist, and the surrounding mountains were covered with snow, but the pool was not frozen.
Looking back at the source, I saw several huge rocks above the pool, and several clear and misty springs gurgling out from the gaps in the boulders, winding down, and finally pouring into the pool.
It's just that there is only a place where water comes in, but there is no way out.
Fang Jun suddenly became beautiful. He thought about building a house here and building two baths. He could take a leisurely bath in the hot spring with Wu Meimei in his arms, admiring the white and smooth skin and the charming flower-like dimples. By the way,
Do some exercises that are good for your body and mind. Don’t let this day be too beautiful...
Such a mountain villa, with its own courtyard, beautiful mountains and hot spring water. In his day, would he have spent tens of millions?
What I didn’t say is that we must build a house!
It's just that it's winter now, so the house will definitely not be built for the time being, and construction will have to wait until next spring.
But building a greenhouse is no problem.
This is a sunny hillside, and it is in a small mountain depression. The temperature is already slightly higher. We only need to tear down the row of broken houses in the blacksmith shop. Anyway, iron is not made there in the winter. They will be built again in the spring.
The bricks and stones that came down are enough to build this greenhouse, and can also lay out a fire pit.
As for whether the walls of the greenhouse being built at this time will be frozen before they are dry, it is not a big problem.
At best, a few load-bearing pillars should be set up in the shed to bear the weight of the glass. There are no people living in it anyway. It doesn't matter if the pillars everywhere will mess up and affect the work. The walls are more used to block the cold wind and keep heat, as long as there are no leaks.
Already.
However, this greenhouse cannot be built in a day or two, so the fire kang happened to be built at the right time. It was too cold in the second half of the night...
Dang even led a group of craftsmen back to the blacksmith shop and started smashing them with bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang bang.
The old fire bed in the house was dismantled, causing everyone in the village to come out to watch. They wondered what kind of madness Erlang was having...
