"Hey? Is this really useful?"

"It's okay. Trust me."

Are the children real? Spread ash on the field with the face.

The area around here is heavily rained in winter, and the amount of rain has recently increased.

Rain is slightly acidic because the carbon dioxide in the air is dissolved.

This field that absorbs the rain should be slightly acidic soil.

And wheat is vulnerable to acidic soils.

So it is necessary to soak ash and neutralize it.

That's why we are sowing ash.

Plants have different preferences for acidity and alkalinity.

Be careful in that area.

The field this time is one and a half times the area where cubs were raised.

There are various reasons, but the big thing is that my physical ability has improved.

Can take care of enough.

"Next is handmade fertilizer."

I lift the fertilizer in the earthenware.

Instead of throwing away cow and goat droppings, they are hardened in one place and fermented together with the fallen leaves of the forest.

I didn't make it in time for Cub, but now I can use it.

The children were told that it would be impossible to put cow dung in the field, but they convinced us that the nuts we eat are always growing in forest soil mixed with animal dung.

I thought about human dung, but I hate myself and I'm afraid of parasites, so I won't do it.

Parasites or too bad.

After adding fertilizer and ash, stir this time.

You have to get it all over.

The cow, me and the children work together to cultivate the field.

Work speed is quite fast.

The strength of the cow is above my strength.

If it is poor, it may be better than ordinary rural work efficiency.

"Let's do it for today. Work will be done tomorrow and the day after tomorrow."

"I agree! I'm tired. Let's cook."

"What is today's rice?"

"Always with you"

"Is it a nut? ..."

"How does Griffon collect a lot of nuts?"

The children start preparing for dinner while talking.

When I first came, it was quite jagged.

Others from different places of origin.

In addition, many children were stunned because they could not escape the shock of being abandoned by their parents.

There is no such situation now.

Everyone looks fun.

"let's go?"

Tetra pulls clothes.

"Oh, I know."

I went to everyone.

...... How many children will leave me next year if it is not famine?

_______________

"Agriculture ... the difference between when you're busy and when you're not busy is terrible."

"Yup……"

Several weeks have passed since the sowing of the wheat seeds.

Farming when not tilling or harvesting is weeding and pest control.

Weed removal is not so hard if you do it frequently every day. Even small children can do it.

Insects do not spring much because of the insect repellent extract.

"By the way, recently, the number of people I see in the forest has increased."

"Because the winter is near, we are feeding pigs with acorns and collecting tree nuts. It is quite serious that there are people in the forest who are afraid of Griffon's anger."

Tetra says with a surprised face.

"Is there any child abandoned this winter?"

"I think people who can't feed have cut it down in summer, but there are people who don't plan, so there is a certain number. But if the next wheat season is bad, a lot will come out."

I have to pray not to be bad.

Will Griffon help newcomers?

I guess impossible ...

Whims are a big reason in our case.

"King Demorgar and Gilbed are not spare time for war. It's ridiculous to lose labor and sorcerers in the war. Soldiers should return to the peasants and the sorcerers should go to pit curses."

"Is there anything other than curse and anti-curse that can help war?"

"... just ask a woman like Yulia"

Tetra grumbled.

That's mean.

"Teach me"

"Then stroke your head."

"Hey."

I stroke the head of Tetra. Tetra laughs happily.

"I'll tell you. Do you know that you can put souls on animals?"

"Oh, I know."

"Then, the story is early. Put the soul on an eagle or dog and do reconnaissance of the enemy. Naturally, the enemy shoots with a bow and arrow to prevent it. Other things can create flames and winds, but dozens of people. "

That's amazing. Especially reconnaissance.

Depending on how you handle it, you can use it like an airplane.

Have the bird carry something like a bomb and drop it over an enemy army.

Don't be a bomber.

It's sober but it can be used unexpectedly.

"Well, I'm thinking of calling Julia to the village after the fall and winter. I want everyone to get to the magic and learn.

"... I don't specifically disagree with Almus's policy."

It seems to forgive.

Was good.

"By the way ..."

"what?"

"Isn't it cold recently?"

"..."

Tetra affirmed with silence.

The season is gradually approaching winter.

As you can see, the winter cold in this area is not different from Japan. Conversely, it's that cold.

Griffon wears fur made of animal fur, but every person has only one. Cold and enemy.

"I'm going to spend more time in the house in winter."

I want a warm fireplace.

I need to prepare firewood now.

Ah ... I guess smoke is amazing when I fire wood in the house.

what to do……

That's it. Let's make that. While we have time.

"What happened? Almus"

"Let's go cut the tree now"

I thought it was a good day.

____________

Charcoal has many advantages.

The big advantage is the long burning time. The firepower is stable. And no smoke.

Of course, there are drawbacks.

It is faster to burn wood directly for pure thermal and thermal efficiency.

In fact, the fuel for a fireplace is firewood.

That's why I really want to use wood to keep warm, but if I use wood, it emits smoke.

There should be a chimney, but there is no chimney in the pit dwellings.

If we try to keep wood warm in our house, we will be smoked.

Well, how to make charcoal is not that difficult.

If fired in a place with low oxygen, the wood will not burn and will replace charcoal.

Heat in a place with low oxygen.

There was such a facility somewhere ~

"That's why I use an anama kiln"

"Did you need this front?"

Noisy. Thank you for explaining it.

"Anyway, if charcoal is made, it won't be frozen or smoked in winter."

I pack the wood in the pit kiln.

If air is not enough, it will not be possible, so spread as much as possible and put dry dead leaves in the gaps.

"Then, fire."

I lit a torch.

The wood inside starts to burn.

"After a while, we will close the hood and the smoke pit. Leave it for a day to make charcoal."

"Isn't it much different from Sueki?"

"Well, it's the same thing if you don't react with oxygen."

"Hey? What is oxygen?"

Oxygen explanation ...

I don't have a good explanation ...

"Oxygen is what you need to burn things. It's a kind of air. Things don't burn without oxygen."

"Hmm. Isn't oxygen burning?"

Fucking. Don't mess around.

I'm a literary person, so I don't know if I can ask the right answer even if I ask such a scientific question.

"Well, the first thing that burns is when carbon or a substance contained in our body is combined with oxygen. So, not only oxygen is burning, but oxygen is burning. Is it correct? "

"Hmm. I understand it somehow."

I'm getting lost.

Was this good definition of burning in the first place? Is burning iron is also associated with oxygen? Isn't it limited to carbon? What is the difference between burning and burning in the first place?

General and chemical terms?

A high school teacher said that oxidation was a reaction between oxygen and other substances.

Oxidation also deprives a substance of hydrogen.

Surely oxidation is the matter that loses electrons.

So it's not acidification.

I don't understand.

Don't use misleading terms.

Most of the time, when I was in junior high school, I learned that oxidation is the combination of matter and oxygen.

Don't change the twilight claim.

I don't understand why.

"Hey, brother. What's wrong?"

"No, nothing. I was just thinking a bit."
