Mahwa tannins
Leon filled the work container with the magic circle painted on it with oil, which is a magic purifying agent, bought from the Alchemy Guild, and soaked the leather of his sneakers there and pickled it.
Usually this takes about a week.
But Leon couldn’t afford to waste that much time.
Leon, who had lost every minute of each day, activated the magic circle installed on the bottom of the work container in advance and injected magical power into the oil.
Then, the ingredients that purify the magic from the oil penetrated into the leather, and the purification work was completed in an instant.
It was bought at a fairly high price, but Leon reacted boldly to Magi, pouring out the contaminated oil and filling it with brine this time.
Although it has been purged with holy oil once, only Magi can purify it with holy oil.
In addition to that, there were many cases of bacteria and mold growth on the hides of monsters that are close to wild animals.
Leon, who had retrieved the salted leather, put the leather in a washing machine that had been engraved with a magic circle and washed it.
After removing the dirt or blood attached to the leather, fill the working container with lime water and soak it for a full week.
Of course, even in this work, Leon used a magic circle to directly penetrate the lime water into the leather, shortening the process time.
The leather that was pulled out immediately was puffy, but Leon used a planer to scrape off the subcutaneous fat layer to separate the dermis layer, then spread it on a round log to remove the hair using a curvature.
The pores of the leather infiltrated with lime water were enlarged to make it easier to remove the hair, but if there was one of the most difficult processes in tanning, it was this part.
‘Hands, a lot, go….’
Although Leon’s body was strengthened with magical powers, his body was at most 8 years old and had a small height of about 125 centimeters.
What an adult would have done with a single gesture, Leon was only able to accomplish it by repeating it two or three times.
After the splitting process was completed, the next step was the deliming process.
The leather soaked in lime water has a strong basicity, and the process of removing the alkali is called demineralization.
Materials containing acidic components, such as cow urine or pigeon dung, have been used here since ancient times, but they were not readily available.
So, the material that Leon came up with was chicken manure.
If it was chicken dung, it could be easily obtained from a poultry farm operated within the territory.
While the chicken manure is soaked in water for deliming, Leon grinds the fruit of the raquois to extract tannins, and then processes the delimed hides by immersing the tannins in the raqueurer.
This process is called tanning, and when the polyphenol aromatic compound contained in the tannin binds to the amino group in the collagen forming the leather and becomes stable, it does not decay, heat resistance increases, and it retains elasticity that does not harden even when dried in the sun.
Usually, it takes about 3 months for all the proteins in the leather to react with tannins and chemically change, but Leon shortened the process again using a magic circle.
Then, thread the edges of the extracted leather on a string, pull it tight, and hang it on a drying frame to dry it in the sun for two days. An environment was created to allow artificial sun sterilization to take place.
Thus, the tanned leather had a pitch-black color with no luster, as if it had swallowed up all the surrounding light.
What is even more surprising is that the leather of the sneakers only absorbs light, but the material is not hard, but the leather of the sneakers processed by Leon’s hands was hard enough that even a knife could not easily pick up.
The secret lies in the fruit of the raquerah.
Monsters were creatures that were born from ordinary creatures being contaminated with magic.
And the identity of this disease called Magi was none other than a class of malignant tumors such as cancer.
The power of a demonic god that triggers cell mutations in the process of cell differentiation at an abnormal rate and reborn as a monster.
However, the mutations caused by Magi are not indiscriminate mutations.
Because it is a mutation that changes to a cell with traits suitable for the demon realm in a harsh environment, the creature infected with the demon becomes stronger than before.
From that point of view, the F-grade plant type monster, Raqueror, was a very strange monster.
In order to survive the fierce competition of predation in the Demon Realm, the Raquerors focused on mutating themselves to taste rather than becoming stronger.
In other words, if the special ability of Sneakers is the ability to climb walls without being seen, hearing, and climbing walls, it can be seen that the special ability of the Raquerquer lies in the astringent taste of the fruit and the magically mutated tannins, that is, tannins. .
Mahwa tannin was a magical alchemy material that reacted with the protein of the leather to give it antiseptic, heat resistance, and elasticity, and at the same time add durability like an iron plate.
Once he succeeded in processing the leather, the problem was that Leon did not know how to make clothes.
If it was just to hide the face, it wouldn’t matter if it was ragged, but the robe made with this was the activewear that the attacker Leon would wear in the future.
And the position of an aggressor was a job that should never be underestimated.
Still, Leon could be easily looked down on because he was young, so there was a need to continue directing himself with clothes and accessories.
In other words, this robe is the face of the attacker Leon.
After all, the leather on the sneakers is very hard, so the average tailor will not be able to handle this fabric.
Leon went straight to the Tailor’s Guild and showed him the sneaker’s leather.
“···Oh My God.”
And the tailor, who came across the leather processed by Leon, could not contain his elasticity as he touched the leather for a long time.
“What the hell did you do to the leather of your sneakers? This texture, elasticity, and durability like a steel plate make it a perfect fabric that lacks anything!”
“Can you make a robe for me to wear from this leather?”
At Leon’s question, the tailor’s face flushed red.
“Please leave it to me!”
The tailor saw Leon’s request as an opportunity to prove his skills to the world.
To that extent, the leather that Leon brought had the most luxurious quality among the leathers he had seen in his life, and above all, the robe was one of the garments that changed greatly depending on the skill of the tailor as it had a simple structure.
Thus, the finished robe became a work that burned the soul of the tailor.
It was a satisfactory completion enough to satisfy the aesthetics of Leon, who lived in the modern world.
“How much will the foundation cost?”
“No, no! You don’t have to give me money. It’s been a huge help to me just to deal with that kind of high-quality leather. But guests…”
The tailor said he wouldn’t take the money, then he paused for a moment and asked carefully.
“Are you not willing to sell the skin to us?”
Apparently, the tailor had fallen in love with the leather that Leon had processed.
Leon originally made a robe and tried to sell the remaining leather to the Alchemist’s Guild or the Merchant’s Guild.
However, the leather of the sneakers that Leon had machined seemed to be so good that even the tailors coveted it.
“Originally, the leather of sneakers is a fabric frequently sought by customers who have learned the martial arts of assassination. Because of their light-absorbing properties, they are excellent at attacking enemies by hiding in the dark. However, the quality of the leather itself is not good. Of course, so far, no guests have taken it as an issue. In the first place, the leather of the sneakers is a fabric to hide from the enemy’s eyes, not to show it to others.”
However, the leather of the sneakers processed by Leon was of such good quality that it was difficult to even recognize that it was the leather of the sneakers.
“The tanner who processed this leather must be a renowned master. Moreover, the durability of the magic is stronger than that of an iron plate. In other words, we can satisfy the needs of aristocrats who want high-quality fabrics and attackers who want solid armor.”
Originally, the customers who wanted the leather of the sneakers were the night customers who wanted to hide their identity or the assassin, but in fact, they are the only ones who want to hide their identity.
In fact, Leon also wanted to hide his identity, so didn’t he process this leather himself?
Rather than assassins, there may be more people who want to hide their identity among the nobles.
The problem is that the leather of existing sneakers is very poor quality for nobles to wear.
In other words, the leather of sneakers processed by Leon is a product that satisfies the double psychology of nobles who want to hide their identity but retain their face.
“Then let’s put up an auction.”
So, Leon’s proposal was to assemble the three forces of the Merchant’s Guild, the Alchemist’s Guild, and the Tailor’s Guild to set up an auction.
The tailor began to set up a place by himself, with the momentum to do whatever it takes to get Leon’s hide.
Meanwhile, Leon brought the finished robe back to the studio to engrave a magic circle on the robe’s lining.
The natural ability of the sneaker’s leather, the ability to offset and interfere with the wavelength of light, is turned into an artifact that makes the face invisible by acting on the inside of the hood.
Leon then put the leather of the sneaker with the magic circle engraved on the lining over the subspace pocket, and took things out of the subspace pocket.
And at the result, Leon smiled.
“great.”
When the subspace pocket was opened and closed, the magical light that was naturally generated was completely offset.
From the side, putting things in and taking things out of the subspace pocket looked like it was touching a completely normal pocket.
After completing the reinforcement of the original robe and subspace pocket, Leon was able to put up the remaining leather at auction.
“Oh My God. This is nonsense!”
“Is this really sneaker leather?”
And the alchemists and merchants on the auction house could quickly grasp the value of Leon’s skin.
Alchemists found value in the ridiculous stretch and durability of the sneaker’s leather.
Usually, nobles wear an artifact called a daily protector in their everyday clothes to protect themselves.
The Daily Protector is an artifact that only enhances durability while maintaining the elasticity of the fabric.
However, the leather of the sneakers Leon brought was not like that.
A ‘daily protector that does not consume magic stones’ that maintains both elasticity and durability by changing the nature of the protein itself.
The alchemists were paying attention to the scientific value of what kind of material in Leon’s skin made this skin like this.
Of course, the merchants quickly grasped such a value, but it was the color and quality that caught their eye more than that.
Leon wore a robe made of sneaker’s leather to the auction, and merchants felt a kind of dignity in Leon’s appearance.
The carefully processed leather was excellent in both texture and fit, and in addition to that, it was covered in pitch-black darkness thanks to the unique nature of the leather of the sneaker that absorbs light.
Originally, it was intended to be inconspicuous, but when it is used in a bright place, it has reached the opposite idea that it looks rather heavy and classy and unique color.
Nobles had a tendency to like unusual things and conspicuous things in order to show off themselves, and merchants judged that it was a product that the nobles would also be satisfied with if it was of this quality.
The most important thing for them is to make money, and the nobles don’t spare money on interesting things.
The three forces, who discovered their respective values in the leather of sneakers processed by Leon, were able to reach an agreement after a tight price competition.
The Alchemist’s Guild decided to purchase 10 pieces for 1 gold and 50 silver per sheet, the Tailor’s Guild had decided to purchase 100 pieces for 1 gold and 20 silver per sheet, and the Merchant Guild had decided to purchase 150 pieces for 1 gold per sheet.
It was the result of purchasing as much as needed, starting with the one with the highest price, depending on the financial situation or circumstances of each faction.
As a result, the amount that came into Leon’s possession was 285 gold.
Leon was able to realize once again that alchemy was a science for making gold.
‘You don’t have to worry about money for a while.’
Once the minimum military funds were prepared.
If Leon’s alchemy skills are the same, it would be possible to earn more money by rolling money based on this military fund, so there was no reason to attack the dungeon.
However, Leon continued his activities as an attacker.
‘What I lack the most right now is a sense of practicality.’
Before returning, he had been on the battlefield for five years, but the reason Leon survived was because he invested all his salary earned as a general soldier in armaments.
After all, the lodging and meals were provided by the unit, so he concentrated on strengthening his armaments by loosing the last penny.
Because Leon’s magic ability, which was at most only 2nd circle, had a higher survival rate when he went out with a sharp sword and a hard shield.
In that sense, in order for Leon to become more proficient in magic, he had no choice but to attack dungeons and accumulate practical experience.
The busy time continued, escaping the castle walls without the family’s knowledge, attacking dungeons, processing the by-products of monsters, and training to increase the circle.
In the midst of forgetting time like that,
“hey. Leon. Aren’t you a little tall?”
Leon had grown a little more.
