Chapter 417: Greenhouse

After sending away Illy and Lyon, Tang En went directly to the Engineering Research Institute.
"Where is Brian?"
The called man said flattered, "Master Brian is in the furnace behind."
furnace?
After Tang En found Brian, this guy was eagerly creating something. Although it was snow outside, it was very dry near the steaming furnace, and even the apprentices were sweating.
"what are you doing?"
"Brother, are you here?"
Brian laughed wildly: "The previous battle inspired me. I decided to create a new type of armor. Trust me, you will love it by then!"
"... Okay, then you come on."
Originally I wanted him to be responsible for building a greenhouse. Looking at him like this, I'm afraid that he couldn't calm down in a few days. Tang En simply went to Nokia.
"Greenhouse?"
Unsurprisingly, Nokia really developed a very strong interest: "Can you explain it in detail?"
Tang En and Nokia talked while drinking hot drinks. He told Nokia about the principles and architectural points of the greenhouse—in fact, he only knew a little about the greenhouse, and only knew whether it was made of glass or plastic. Isolate cold air to keep warm, and grow off-season vegetables in a constant temperature and humidity environment.
However, knowing that this method is feasible, it is enough in Prendall. Uncertain techniques are solved by magic. This is the essence of magic reform.
"I see. It's a fantastic idea, but I don't think it's feasible."
Nokia was stunned by Tang En's idea, but he denied the feasibility of this solution.
Edgar, who was doing nothing beside him, shook his head: "Just changing the environment such as temperature and humidity will allow vegetables grown in other seasons to grow in winter ... I feel so incredible, I am afraid that this kind of thing is only the gods ... Oh, And elves, like Miss Grantia. "
Due to Grantia's recent activity, her popularity in Ellington is quite high. Many people know that the food they eat is derived from Grania, so she is very grateful.
"After all, relying on the power of the Druid is too limited. What I want to solve is a method that can be copied. No matter who it is, as long as a greenhouse is built and implemented according to standards, it can be copied successfully and vegetables and fruits can be grown. "
Although the power of druids is convenient, humans cannot always rely on elves, not to mention the small number of elven druids. How can it meet the needs of the entire human race? Only by relying on human beings is the key to solving problems.
"Well, as you said, give it a try."
Nokia clapped his hands and said, "Anyway, it's snowing recently, and there's nothing serious about the researcher, so let's try it."
Both crystal and universal alloys are available, so they just prepared a little bit and started in the afternoon.
The place they chose was an unleased field outside Ellington. This field had been frozen due to snowfall. The frozen ground was very hard, but of course Tang En was there, which was certainly not a problem.
"Are you sure this method works?"
As the Minister of Agriculture (in nominal terms), Grantia was also called over. The little girl was hiding in Sanye and drinking hot fruit tea, waiting to see the drawing for the first time, but was dragged by Tang En. Come out, I'm full of complaints and nowhere to scatter.
It was clear that there were heavy snow around the goose feathers, and the snow was still thick on the ground, but Grantia was still wearing the emerald green short-sleeved short skirt that she had before.
"Of course it works ... aren't you cold?"
"We elves are races that can harmonize with nature, and certainly not cold."
"... you are not cold-blooded animals."
Tang En is powerless, how big is Nice Claire for the elves?
"For the first time, I will do it myself. Nokia, you will record the key points and tips of the construction and make a standard manual. Be sure to let others follow the manual to copy it later."
Tang En said, with a pair of hands, a twisted vortex appeared over the head, and the universal alloys that had been precisely cut out flew one by one, hanging in the air at a certain distance, There are also some thin pipes connected in between.
As soon as Tang En snapped his finger, the universal alloy pillar fell to the ground "banging", pierced firmly into the frozen ground, and then the frozen soil dissolved and lifted under the action of magic, tightly covering the universal After the alloy, it turned into stone again, and fixed the pillar firmly there.
After all the pillars have been fixed, it is the surrounding wall-because the fence will consume a lot of universal alloys, the current output can not be wasted at all, so Tang En used a very crude solution-soil-based spells .
Use the soil magic stone wall technique to build a solid stone wall, which is cheap and durable.
After the alloy gates were installed on the remaining exits, Tang En began to cap.
Large pieces of colorless and transparent crystals were taken out. After processing, these crystals are very flat and have high light transmittance. They are very suitable for the ceiling of a greenhouse.
Of course, the cost of these crystals is slightly higher. If there is quartz sand and the various shapes of glass are fired, the cost will definitely be further reduced.
The crystal is fixed by the card slot on the universal alloy. After laying the crystal one after the other, the card slot is fastened to the top and is very stable.
These crystals are only as thick as the little finger, but because of the magic array here to protect the greenhouse, there is no need to worry about the sturdiness. The more troublesome is to increase the thermal insulation effect, so the double-layer structure is used-including the stone wall just now. same.
Soon the ceiling was fully sealed.
"Is this the greenhouse?"
Grantia frowned slightly. "Isn't it just a sealed house ... just a crystal on top."
"It doesn't count."
Tang En signaled that everyone had entered the greenhouse. After closing the door, the cold wind disappeared from all sides, but there was still thick snow and cold air inside the greenhouse.
"The reason it's called a greenhouse is because it's going to be warm ... wait a minute."
As soon as Tang En said, "Fire."
I saw a hot flame igniting around Tang En. Those flames turned into a splendid ribbon, flew out, turned around in the greenhouse, and the snow on the ground was melted in a blink of an eye and turned into water vapor. Gathered on the ceiling, frozen on the crystal, and melted again ...
The temperature in the greenhouse rose rapidly, and the hard frozen soil began to return to softness, and all the water vapor was emitted. Soon the entire greenhouse became humid and hot.
"Hoo! It's so boring!"
Edgar couldn't take it anymore, and unbuttoned his shirt. "Magic is incredible. It's so cold winter, it's so hot without a fireplace."
"almost."
After the frozen soil in the field was turned over several times, Tang En dispersed the element of fire. At this moment, the temperature in the greenhouse has risen to 28-9 degrees, and because of the closed double-layer insulation environment, this temperature It will be kept for a long time. If it is full of vegetables, fruits and carbon dioxide, the insulation effect will be better.
"Dikarios, your brother can come over."
Tang En said to the air, and then there was an element of fire out of thin air. The element of fire looked dumbly at Tang En, waiting for his order.
"Element of fire?"
Nokia asked curiously, "Do you want to use the fire element to keep the temperature here?"
"Yes, did you see the stove in the middle? There is a central boiler for all the pipes. If the temperature drops, the fire element will heat up the boiler there, and then the hot water will be transmitted to the entire greenhouse through the pipes, raising the temperature here ... My name is It heats. "
"No one else can hire elemental creatures."
Watching the fire element drill down to the boiler and be in a daze, Tang En smiled, and said, "The standard specification can be changed to incineration boiler to increase the temperature quickly ... In fact, using compost fermentation can also increase the temperature, but the efficiency is too slow. . "
"As for humidity and watering, the water element can help, and the instructions are written according to the previous pipe irrigation technology."
"Besides this, because it is in a greenhouse, it is too troublesome for the agricultural tiller to come in, so the cultivated land can rely on the power of the soil element."
"And after planting a lot of crops, there will be a lot of carbon dioxide accumulated in it. Then you can use the exhaust fan driven by magic energy, or use the power of the wind element ..."
"Lord Lord, what is carbon dioxide?"
"... a colorless gas. If the concentration is too high, it will die. Please mark it."
Nokia quickly wrote down these key data, whether it is double-glazed glass to keep heat, or carbon dioxide, a lethal colorless gas, is very fresh knowledge.
"To show you the effect as soon as possible ... Grantia?"
Tang En waved his hands with a smile, and Grantia reluctantly walked out and took out the vegetable seeds that had been prepared. She just threw them away, and those seeds accurately fell into the opened soil, more than ten acres. Farmland, she finished sowing in minutes.
It takes a lot of time for the seeds to germinate, but in order to let them see the results of the experiment as soon as possible, Tang En asked Grantia to perform a catalytic experiment. As long as they saw that the seeds could grow normally in the greenhouse, the effect was already achieved.
In fact, if he did n’t know how to synthesize the nutrient solution, Tang En would like to directly produce more efficient soilless cultivation. Not only does it take up less space, but the output of many vegetables will also increase a lot. The yield per unit area is more geometric. Progression.
Now, he can only use the greenhouse technology to barely increase the vegetable output here. At least, after the vegetable output goes up, it will fill some food vacancies, reduce the price of winter vegetables, increase the average nutritional intake base of people, and ultimately improve Their overall physical fitness.
Of course, Tang En's ultimate goal is to improve their average combat effectiveness.
