Chapter 417 Greenhouse

After seeing off Eluli and Leon, Tang En went directly to the Engineering Research Institute.

"Where's Brian?"

The young man who was stopped said flattered, "Master Brian is at the furnace at the back."

furnace?

After Tang En found Brian, the guy was building something excitedly. Although there was snow outside, it was very dry near the steaming furnace. The apprentices nearby were even sweating profusely.

"What are you doing?"

"Brother, are you here?"

Brian laughed wildly and said: "The previous battle inspired me, and I decided to create a new type of armor. Believe me, you will definitely like it by then!"

"...Okay, then come on."

Originally, I wanted him to be responsible for building the greenhouse, but looking at him like this, I'm afraid he won't be able to calm down in a few days. Tang En simply went to find Nokia. The dwarf craftsmen should be more interested in this kind of knowledge.

"Greenhouse?"

As expected, Nokia was very interested: "Can you explain it in detail?"

Tang En and Nokia chatted while drinking hot drinks. He told Nokia the principles and construction points of greenhouses - in fact, he himself only knew a little about greenhouses, and only knew that they were made of glass or plastic. Isolate cold air to keep warm, and grow off-season vegetables in an environment with constant temperature and humidity.

But knowing that this method is feasible is enough in Purandar. If the technology cannot be solved, use magic to solve it. This is the essence of magic reform.

"I understand, it's a fantastic idea, but I don't think it's feasible."

Nokia was amazed by Twain's idea, but he denied the feasibility of this plan.

Edgar, who was doing nothing next to him, also shook his head: "Just changing the environment such as temperature and humidity can make vegetables that grow in other seasons grow in winter... I feel so incredible, I am afraid that only the gods can do this kind of thing... Oh, And elves, for example, Miss Grandia can do it.”

Due to Grandia's recent activity, her popularity in Ellington is quite high. Many people know that the food they eat is grown by Grandia, so they are very grateful to her.

"Relying on the power of druids is too limited after all. What I want to solve is a method that can be copied. No matter who builds a greenhouse and follows the standards, they can successfully copy it and grow vegetables and fruits. "

Although the power of druids is very convenient, humans cannot always rely on elves, not to mention that the number of elven druids is so small, how can they meet the needs of the entire human race? Only relying on human beings themselves is the key to solving problems.

"Okay, as you said, you can give it a try."

Nokia clapped his hands and said, "It's been snowing recently, and there's nothing big going on here as a researcher. Why don't we give it a try."

Materials such as crystal and universal alloy were available, so they just made a little preparation and started work in the afternoon.

The place they chose was an unleased field outside Ellington. The land had been frozen due to snowfall, and the frozen soil was very hard. But with Tang En here, of course this was not a problem.

"Are you sure this method works?"

As the Minister of Agriculture (in name only), Grandia was also called over. The little girl was hiding in Sanye's place, drinking hot fruit tea, waiting to see the drawings for the first time, but was dragged away by Tang En. When I came out, I was full of complaints and had no place to express myself.

It was obviously snowing heavily all around, and the snow on the ground was still very thick, but Grandia was still wearing the emerald green short-sleeved skirt from before, and she didn't feel cold at all.

"Of course it's possible...Aren't you cold?"

"We elves are a race that can be in tune with nature, so of course we won't be cold."

"...You are not cold-blooded animals."

Tang En was no longer able to complain. How much trouble did Nisclare cause to the elves?

"This is my first time to build it. I will do it myself. Nokia, please record the key points and key points of the construction and make it into a standard instruction manual. Make sure that others can copy it according to the instructions in the future."

As Tang En spoke, he opened his hands, and a twisted vortex appeared in the sky above his head. Precisely cut universal alloys flew out one by one, hanging in the air at a certain distance, one after another. There are some thin pipes connecting them.

As soon as Tang En snapped his fingers, the Wanyong alloy pillar fell to the ground with a "bang bang" and pierced firmly into the frozen soil. Then the frozen soil dissolved and lifted under the influence of magic power, tightly wrapping Wanyong After the alloy, it turned into stone, firmly fixing the pillar there.

After all the pillars were fixed, there was the surrounding walls - since the walls would consume a lot of universal alloy, the current production could not be wasted like this, so Tang En used a very crude solution - earth spells .

Using the earth magic stone wall technique, a solid stone wall was built, which is high quality, low price, strong and durable!

After installing the alloy gates on the remaining exits, Tang En began to cap them off.

Large pieces of colorless transparent crystal were taken out. After processing, these crystals were very smooth and had high light transmittance. They were very suitable for use as the ceiling of the greenhouse.

Of course, the cost of these crystals is slightly higher. If quartz sand is available, the cost will definitely be reduced further after firing glass of various shapes.

The crystal is fixed through the slot on the universal alloy. After laying the crystal on, the slot will be firmly buckled on it, which is very stable.

These crystals are only as thick as your little finger, but since a magic circle is set up here to protect the greenhouse, there is no need to worry about its sturdiness. The more troublesome thing is to increase the thermal insulation effect, so a double-layer structure is used - including the stone wall just now. Same.

Soon the roof was all sealed.

"Is this a greenhouse?"

Grandia frowned slightly: "Isn't it just a sealed house...it's just topped with crystals."

"That's not all."

Tang En signaled everyone to enter 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 why it's called a greenhouse is because it will be very warm inside...wait a moment."

Tang En snapped his fingers: "Fire."

I saw blazing flames instantly ignited around Tang En. The flames turned into a brilliant ribbon, flew out and circled in the greenhouse. The snow on the ground melted in the 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 become soft again. All the water vapor inside was emitted, and soon the entire greenhouse became humid and stuffy.

"Phew! It's so boring!"

Edgar couldn't stand it anymore and unbuttoned his shirt: "The magic is incredible. It's such a cold winter, but it's so hot without a fireplace."

"about there."

After the frozen soil in the field was turned over several times, Tang En dispersed the fire element. At this moment, the temperature in the greenhouse had climbed to 289 degrees, and because it was a closed double-layer insulation environment, this temperature It will last for a long time. If it is planted with vegetables and fruits and there is more carbon dioxide, the insulation effect will be better.

"Dikarios, your little brother can come over."

Tang En said something into the air, and then a fire elemental appeared out of thin air next to him. The fire elemental looked at Tang En blankly, waiting for his order.

"Fire element?"

Nokia asked curiously: "Do you want to use the fire element to maintain the temperature here?"

"Yes, do you see the furnace in the middle? That is the central boiler for all the pipes. If the temperature drops, the fire element will heat 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 get under the boiler in a daze, Tang En smiled and said: "The standard instructions can be changed to incineration of the boiler to quickly raise the temperature... In fact, if compost is used for fermentation, the temperature can also be raised, but the efficiency is too slow. .”

"As for humidity and watering, you can let the water element help. The instructions should follow the previous pipe irrigation technology."

"In addition to these, since it is in a greenhouse, it is too troublesome to bring in an agricultural cultivator, so the cultivated land can be cultivated with the help of the power of the earth element."

"After planting a large number of crops, a lot of carbon dioxide will accumulate in it. At that time, you can use an exhaust fan driven by magic energy, or use the power of the wind element..."

"Lord, what is carbon dioxide?"

"...a colorless gas. If the concentration is too high, it will kill people. Please mark it specially."

Nokia quickly wrote down these key data. Whether it was the ability of double-layer glass to retain heat or carbon dioxide, a colorless gas that can kill, it was all very new knowledge.

"In order to let you see the effect as soon as possible... Grandia?"

Tang En waved his hand with a smile, and Grandia reluctantly came out and took out the vegetable seeds that had been prepared. She just tossed them casually, and the seeds fell accurately into the turned soil, covering more than ten acres. She finished sowing the farmland in minutes.

It takes a lot of time for seeds to germinate, but in order to let them see the results of the experiment as soon as possible, Tang En asked Grandia to conduct a catalytic experiment. As long as they can see that the seeds can grow normally in the greenhouse, the effect has been achieved.

In fact, if he didn't know how to artificially synthesize nutrient solutions, Tang En would have wanted to directly create a more efficient soilless culture. Not only would it take up less space, but the yields of many vegetables would also be greatly increased, and the yield per unit area would be even higher. Level improvement.

Now, he can only use greenhouse technology to barely increase the vegetable production here. At least when the vegetable production increases, it will fill some food vacancies, reduce the price of winter vegetables, increase people's average nutritional intake, and ultimately improve Their overall physical fitness.

Of course, Tang En's ultimate goal is to improve their average combat effectiveness.
