Chapter 751 Gretel: You split the soil for half a month? ! (Ten Thousand Rewards Plus Two)

Under the Lord of Thunder's sect, no matter how big or small, one counts as one.

Except for the Thunder Master himself, the two highest-ranking disciples, and Gretel, who enjoys privileges, the rest were all dragged into the wilderness.One person is in charge of a field, and there is a subtle and strange smell everywhere in the air.

Dejected, Aurora crouched at the edge of the field he was in charge of.After half a month, his robe was also crumpled, and his boots were covered in mud.The underwear and jacket on his body smelled bad, and the underwear rubbed against his skin, making his whole body itchy.

After half a month, every time he took a step, he slapped a cleaning technique on his boots (he was scolded bloody by the teacher);
When I got to the edge of the field ridge, while the teacher was not paying attention, I secretly patted the cleaning technique on the boots;
After half a day's work, when it's time to eat, take turns to pat the cleaning technique on your hands, clothes, and boots;

After a whole day of work, I dragged my tired body back to the campsite before tidying up for myself...

It is true that people fall very fast.Just like this, I will be laughed at by the older brothers and sisters:
"Aurora, you are really spoiled and spoiled, and you can't bear this bit of hardship. When we are adventuring in the wild, who will use the precious magic power for cleaning?"

Huh, I want to go back to Nevis, I want to go back to the Mage Tower... With Gretel, I just need to do experiments in the laboratory and meditate in the meditation room every day, clean and comfortable.

After so many years, since when did he suffer in the wilderness!

"Aurora! It's time to start!"

"Yes!"

He shuddered and responded loudly.Then, close your eyes, meditate, chant mantras, and channel magic power...

"Crack!"

A blue-white electric arc shot out from his hand, and landed on two long poles in a straight line in front of him, 20 meters apart.The top of the long wooden pole is equipped with a metal joint, and the iron wire below is directly guided into the ground.The arc shot out, and the tops of the two long rods lit up at the same time.

The third-level spell of the evocation system, lightning bolt, is done!

Immediately there were skeletons plopping into the field, and three samples were randomly taken at three distances from the place where the wire entered: near, middle, and far.Dig, package, and send to the field.

In the shed next to it, the alchemists set up the instruments, began to dry quickly, weighed the soil samples, added medicine to boil, cooled, filtered, and constant volume...

"Record! Lightning beam for the third time! Released by a sixth-level magician! Normal output!"

"The nitrogen content of the soil near the center is 1.70 grams per kilogram of soil!"

"The nitrogen content of middle-distance soil is 1.47 grams per kilogram of soil!"

"The nitrogen content of long-distance soil is 1.33 grams per kilogram of soil!"

"Range of Lightning Beam, 40*20 meters!"

"Increase the total amount of nitrogen in the range..."

Aurora gasped for breath.He kicked high, kicked low, moved to another field, and cast the spell again——

If I don't finish tossing the spell today, I won't let him go...

A magician of the evocation system, and a magician who can release lightning spells, used various methods to test in turn.Some release lightning into the air, some cast spells on long poles, and some cast spells directly on the ground;

Some directly chop, some attract cumulonimbus clusters, and then make the cumulonimbus clusters flash and thunder;

There is also a large bottle filled with water, and a discharge rod is inserted on each side of the bottle to control the water flow to continuously spray upwards.Then discharge it into the air above the water surface, then drop litmus reagent into the water, and watch the water turn red...

The Magic Council did not spare any manpower, and under the intensive experiments of the disciples and grandchildren of the Lord of Thunder, the Council soon came to a conclusion:
The existing magicians of the evocation system - except for the Lord of Thunder himself - exhausted all their spells every day and worked hard to attract thunder every day. Probably, they can satisfy one-twentieth of the nitrogen fertilizer for the fields of the whole country?

And this group of people can't all be busy trying to attract thunder.Evocation magicians are one of the most powerful and lethal factions in the Magic Council, fighting on the front line all year round.All go to lead the thunder, and the combat power ahead will have to take time out of the boss.

"It's enough to feed the parliament and its related people...Aren't we thinking too much if we want to feed the whole country?"

Old Sam bit his quill sadly.The nature of a magician, loves academics, and advocates freedom.The council issued a mandatory task to let evocation magicians go to the fields to test the ability of lightning to increase nitrogen fertilizer for the land. That's fine, everyone has the right to do experiments;

Let them stay in the fields for three and a half years, hacking every day, moon and moon, sunny days and rainy days.Not to mention the contribution points spent by the parliament for this, the coercive force required is also a great consumption of the authority of the parliament.

——You must know that evocation magicians have strong fighting power, and they are also the most powerful group of people when they make a fuss.Bomb them down to do experiments, thanks to the words left by the Lord of Thunder before he left.

"Otherwise, we save a little less food? After all, there are so many nobles in the kingdom, the Temple of the God of War, and the Temple of Spring Water, so we can't expect our family to worry about it..."

"That won't work." The great magician Grom turned his head sullenly.A necromancer is also a mage, a living person, not a lich, and he also needs to eat, and he doesn't want to see the kingdom go hungry.And importantly...

"We're cooperating with the Deism! The old guys from the Deism, looking at the hungry people all over the place, can you bear it?! ——It's up to them to produce crops in the final analysis!"

"Uh... let's think about it again..."

Think of a way, think of a way, the way can't be figured out in a short while.A large number of magicians were involved in the experiment, and at the same time, most of the evocation magicians, including Aurora, got a short vacation.

"But I'm back! I'm back! Moss! Boil hot water! Put water in the bathtub! Get me clothes! I want to take a good shower! After washing, take a bath! I want two invisible servants to help me wipe my back!"

Gretel looked at Aurora in surprise.I haven't seen you for half a month, and Aurora has completely changed her appearance. From top to bottom, she looks like she was pulled out of a sauerkraut jar——

The blond hair was messy and tangled, the clothes were wrinkled, and the boots were completely invisible.Covered in a layer of dust all over his body, he walked by, step by step-the invisible servant followed behind and swept hard.

Coupled with the sour smell all over the body, it is possible to say that it was fished out of sauerkraut in the earth pit.

"What's wrong with you?"

"Don't mention it! We were dragged to split the fields! Split the fields!"

An hour and a half later, Aurora, white and wrinkled from the soak, sat in front of Gretel's new hot pot in her silk pajamas.Pour down a plate of mutton, roll it a little, and then quickly fish it up:
"Hiss... ha, lying dead, many times." He was panting from the burn, breathing hard with his mouth open, and at the same time stuffed mutton slices into his mouth like a starving ghost.Chewed and splashed, and at the same time did not forget to slur:

"Split the field dozens of times a day, finish the lightning beam, use the electric shock ring, summon electric claws and cumulonimbus clouds...every day exhausts all spells! All of them!" He complained bitterly:
"I can only sneak a few cleansing techniques to clean my clothes and shoes..."

"Don't you have servants to serve you?" Gretel was surprised:

"Impossible! The council drags you to work, and you have to arrange someone to serve you!"

"That's for sure... But the work of servants and washerwomen is the same thing. The laundry is not clean, the clothes are not dry, and it happens to be rainy for a few days. Hey, it's not as good as me Take two shots with the cleansing technique!"

... Judging from the miserable situation when you came in, your level of cleaning skills is just that...

Gretel groaned, and silently moved the peanut butter bottle, sesame oil bottle, and various sauce bottles to Aurora one by one.I leisurely put radish slices, cabbage leaves, mushrooms, and various vegetables into the mutton pot...

There is no way, I ate too much mutton, and I really got a little angry, so I need to eat something light to reconcile it.

Aurora gobbled it up and ate a dozen or so plates of mutton before collapsing in satisfaction.He half-lyed on the sofa on one side, let the invisible servant pinch his legs, and hummed weakly:
"It is said that we have to go...to rest for two days, and to pull it up again...It has been tossing for three and a half months...It is said that it is up to us to increase the fertility of the soil..."

rely on you?
Are you relying on artificially induced lightning to fix nitrogen in the soil?

Gretel thought about it, and immediately felt that the painting was beautiful.It is said that in the previous life, which country developed chemical fertilizers, it did not rely on large-scale industrial production.It is necessary to set up lightning rods all over the ground to attract thunder to apply nitrogen fertilizer to the fields...

At least half of the people in the world will starve to death.

"By the way... have any of you tried to use other methods to produce nitrogen fertilizer?"

"Do you have a way?"

Aurora immediately jumped up from the sofa, staring at Gretel with bright eyes.Climbing out of the bathtub, he had another big meal of hot pot, his flushed cheeks, the color deepened, and he was almost on fire:
"It's a mystery, you must find a way! I don't want to go to that ghostly place again! Let me squat on the edge of the farmland and chop the fields for three months, it is better to let me die!"

Death is probably not going to die, and it is really uncomfortable to suffer.The main thing is, let these evocation magicians lead lightning to fix nitrogen, it is better to let them take out the chemical fertilizer industry——

By the way, how should industrial nitrogen be produced?

The earliest method in my impression is Haber’s nitrogen production method. Germany was forced to die before World War I. It didn’t matter if there were no resources or no resources. Haber’s chemical strongman came up with it... So what are the details?
I definitely haven’t learned it in books, but the usual extended reading, the teacher’s casual narration, the chatting of classmates to show off their knowledge, and the patient’s hilarity, it should be mentioned, right?
Gretel searched the memory bit by bit.It seems that synthetic ammonia can be produced by mixing nitrogen and hydrogen at a high temperature of 600 degrees and a pressure of 200 atmospheres.

As for how to produce a large amount of pure hydrogen, how to produce a large amount of pure nitrogen, and get rid of the oxygen in the air, he was quite at a loss.It seems, it seems, what catalyst is needed for the reaction of hydrogen and nitrogen?
what's going on?

　Thanks to @强大大海虎 for rewarding 1500 starting coins

　　I was checking the information today, how much lightning can produce how much nitrogen fertilizer in the soil, I checked three papers and N irrelevant papers, but I couldn’t find it

　　Then, I found it in the high school chemistry question bank...

　　(run away crying)
　　Then the difference in nitrogen content before and after fertilization was copied from another paper on measuring soil nitrogen content.However, the nitrogen content of the soil that grows wheat and the soil that grows rice must be different, and I am not responsible for the accuracy of the data here...
