Einar, who was massaging his waist, could only blame himself for his pleasure lust from two days ago.

\'I think I should stop being so greedy and should start getting my wives pregnant again for my safety.

I don\'t know how people in the future want to have a harem when having three women is almost impossible to maintain.

I think they confuse having a harem and having lovers, it may be easy for them to have two or three lovers, but it is not the same to see a woman on different days.

Than having three young women demanding love, thank goodness my body is toned from years of training, otherwise, I couldn\'t resist. \'

Einar sighed and closed his eyes \'I will never think with my penis again. The pleasure may be momentary but the suffering is endless.\'

After opening his eyes he looked at the white stone in front of him with a smile "To think that we would find an apatite deposit near the hot springs.

With this material, everything is going to change for the nation, but the first step is to separate the phosphorus from other materials in the apatite. "

Einar then took a mortar and began grinding a quartz crystal into powder.

Wiping the sweat on his forehead, he placed the quartz powder in a small earthenware dish, then took a small apatite stone and began to grind it.

"Although I do not know the amount of calcium in apatite, it should be composed mostly of phosphorus but it should also have other substances such as flour or chlorine.

But that\'s the beauty of being in the dark ages of humanity. Everything you know can be a discovery of centuries.

Although that implies having to replicate the discoveries in order to achieve development. "

After this, Einar placed the apatite powder in the clay dish where the quartz powder was.

"If I remember Woheler\'s method correctly, silicon dioxide or quartz should react with carbon phosphate to produce phosphorus.

But first, let\'s see if this method works. "

Placing the clay plate on a small campfire flame, he let the materials begin to heat up.

At that moment, he could see how the silicon dioxide reacted with the carbon. Creating a red substance that had some imperfections, Einar could distinguish the dust as red phosphorus.

"So the Woheler method works perfectly, but now I have to produce carbon sulfide."

Putting aside the red phosphorus, he put charcoal powder and sulfur powder in a glass dish, then using an alcohol lamp he heated the powders.

In a short time, a black, pasty substance with an unpleasant aroma was formed.

Einar, who was already wearing ski goggles and a cloth on his face, separated the plate from the fire.

"Now I can remember well the first matches were made of phosphorus and sulfate, although they were not very safe they were better than lighting a fire in the traditional way."

Using small wooden sticks, he spread the carbon sulfate on one end of the wooden sticks.

Later he put red phosphorous powder on them to cover them completely. When he was done, he let them dry in a glass dish.

It was at this time that Einar opened the glass windows of his laboratory and placed the carbon sulfide in a glass jar so that it would not release the toxic gases.

When he finished, he entered the bathroom of his laboratory, where he took off his clothes and washed his body to eliminate any kind of toxic residue.

Because he had to take care of his children and he would not put them at risk because of an oversight on his part. When he finished, he opened the bathroom door that led to the hall, where he spent time with his family.

The next day Einar returned to the laboratory, where the first thing he planned to check were the matches he had created the day before.

When he approached the matches, he put on reinforced leather gloves and his ski goggles in case an accident happened.

"As I can remember, the first matches were quite dangerous because if they rubbed against each other they could light.

I hope that what I remember from the military school investigations may have served. I would feel terrible if it did not create a reaction.

Because in that case, I would have to find where the production process failed, which would delay me for a long time. "

Taking two matches, he rubbed them and it was then that a disgusting aroma could be smelled in the environment while a fire was lit in the two matches.

With a smile on his face and containing his desire to vomit, Einar could only feel proud because with the matches the flint will take a back seat.

All he had to do was make a case of hardened paper so that the matches could be stored, thereby ensuring that they would not light.

"Well, since we have matches, I think I could make packs of 40 matches that could be used 20 times because another match is required to be lit.

The materials are cheap so all soldiers and warriors will be able to receive matches in their belongings to improve their quality of utensils.

As for civil use, I will have to wait until I find a way to laminate the wood to make the wooden sticks in a simple way.

I will not be able to profuse too much as I will have to spend time making the wood, but that is a small step that can be ignored.

When the next traders arrive, we should be able to have enough labor force to build a factory to make phosphorous and sulfate from coal. "

Putting the used matches aside, Einar smiled and looked at the red match on the table.

"Now is the time to create the first chemical phosphorus fertilizer to improve crops. If something is missing on the island, it is arable land.

But that is not a disadvantage, if fertilizer is used correctly, I can produce on this land the same amount of grains that the Frank empire could even double the amount produced.

The future is scary when compared to the past where there is hardly any grain production. "

Because Einar only knew that John Lawes had been the first creator of the chemical fertilizer using sulfuric acid and phosphate rocks.

First, he planned to put in sulfuric acid and a leak of apatite, wait for the acid to dissolve everything.

Later use limestone or calcium carbonate to neutralize the sulfuric acid, after this he would use a paper filter to strain all the content.

If his understanding was correct, the residue on the filter should be the potassium fertilizer.

But if he was wrong, nothing happened because he planned to use distilled water to clean the substance that could remain in the neutralized acid and use it as the fertilizer.

To prove that he had done things correctly, he had five pots with which he would try to sow some wheat.

One of them would be the guide pot where nothing would be used to measure harvest time, although he wanted to try something more exotic, like tomato seeds.

Who had brought the Natukt tribe, he knew that if he failed, part of those seeds would be lost, so he could not risk it.

To begin the experiment, he placed sulfuric acid in a precipitated glass and later placed the apatite stone with tweezers.

Which dissolved slowly in the acid. At all times Einar was using a thermometer to measure the temperature of the precipitated glass.

Because sulfuric acid could cause exothermic reactions which would increase the temperature drastically.

After about three hours the phosphate stone had almost completely dissolved, leaving only some lumps that did not dissolve with the acid.

To neutralize the acid and prevent it from contaminating the water, Einar used a small limestone that was composed mostly of calcium carbonate.

At that time a reaction occurred, and the acid bubbled for a few minutes, to check if the acid neutralization was working.

Einar lit two of his matches and placed them on the precipitated glass. The matches went out almost immediately as carbon dioxide was being produced.

Which showed that the acid was being neutralized, when the substance finally stopped bubbling and the acid was completely neutralized.

Einar used a paper filter to strain the substance, leaving the small lumps like what he thought was the fertilizer.

All those lumps he rinses them with distilled water and put them on 2 of his pots so that they will work as fertilizer.

Later, he turned his attention to the liquid in the glass. He started using distilled water and many paper filters in order to make the substance as clean as possible.

When he finished, he put some meat on the substance to see if the acid was completely neutralized, but nothing happened.

So he put the liquid in two other pots. With the experiment finished, he would only have to supervise to be able to know if it was a success or failure in the production of the first fertilizer.

"Now it will just be a matter of waiting, but while I do, it is time for me to teach artisans how to create carbon sulfate and how to get phosphorus from apatite with quartz powder.

The matches will be a precious material that will help us a lot, perhaps even a box of 40 matches can be sold to the merchants for one slave.

It seems like a fair deal for this time that I was not with my family. "
