The advent of stamping machines, cutting machines, and grinding machines can certainly improve efficiency, but it is still a little short of time to fundamentally change the world.

After all, large-scale industrial production is not yet possible.

The biggest credit for the emergence of these three machines is still on Donn, because the core is the magic constructed by Donn.

The constant levitation technique on the battering hammer has a gravity amplification magic array attached to the judgment condition, and a stable adjustable whirlwind magic array that pushes the cutter and friction grinding wheel......

What magician but Don would do these things?

Those who are willing to do it are not capable, and those who are capable will not do it, so these things can only be done by Don.

The time that really changed the times was when all magicians were willing to do these universal applications of magic.

"You've been producing those farming tools for the past two days, and then there's something else for you to do."

Tang En smiled: "Since you said you want to mess with me, don't blame me for making you too tired, say in advance, your recent task is very heavy." ”

"No problem, big brother, you can rest assured!"

Brian patted his chest and promised: "The mission will definitely be completed beautifully for you." ”

The originally heavy and boring tasks have become extremely easy with the addition of these three machines, and Brian can certainly complete them easily.

Of course, Edgar wouldn't say anything, not to mention that it was the lord's order, and the value of the Aujin ingot that Don gave them alone was enough to keep them working for more than ten years.

"Well, I'll come back the day after tomorrow and hope you can get all the work done...... Well, get me some iron ingots. ”

By the time Donn left, Brian and Edgar were already in the heat of the day.

What is Don going to do? Going back to mint, of course!

He and Fiona have a bet on it!

Back in the bedroom, Don shook his head to himself.

"It's still not good to have an alchemy laboratory, and many experiments in the future may need to use an alchemy laboratory, so let's take the time to build one."

Although it is time to build one, it is still a question of when it will be built, because there are many tools and materials in the alchemy laboratory, and Ellington can't get them, so if you want to build it as soon as possible, in addition to waiting for Ellington to develop and bring the caravan, you can only consider going to other cities to buy it yourself.

The matter of the alchemy laboratory was put on hold for the time being, and Tang En picked up a piece of mint and groaned.

Peppermint, in addition to eating, any other value is established in its essential oil, so if peppermint wants to play an economic value, it is necessary to have a set of low-cost, fast-acting essential oil extraction methods.

And what Tang En knows in his impression is only the distillation and condensation method, which happens to belong to this kind.

Neither the distiller nor the condenser, nor the subsequent separation of water and essential oils, are too technical, and the biggest difference between distillation is water distillation, water distillation, and steam distillation - but for Donn, it doesn't make much difference for the time being.

"Let's try it first."

After roughly recalling the structure of the still and condenser, Don began to get to work.

The iron ingots brought back from Edgar were rapidly stretched and twisted by the magic, and soon became a hollow still, and the condenser tube on the other side was also successfully formed.

"It's still beautiful in glass."

Don pouted, iron stills and condenser tubes are of course not good on earth, but it doesn't matter here in Donn, under the effect of magic, whether it is heating or condensing, it is very simple and convenient.

He took some water from the air and introduced it into the still, added the right amount of mint leaves, connected the condenser tube to the container, and he started heating it directly.

The magic array under the distiller emitted heat steadily, and soon the water inside began to tumble, and then Tang En activated the magic array covering the condenser tube, the ice magic array is a variant derived from the water magic array, under Tang En's adjustment, the temperature is steadily and permanently reduced, and the condensation effect can throw off the condensation equipment on the earth more than a dozen streets.

Under Don's personal operation, this rudimentary set of equipment was only made into a can of semi-finished products in just a few minutes.

Tang En smelled the fragrance in the jar and raised his eyebrows: "The oil yield is so high?" ”

The quality of the mint here is unexpectedly good, and after the bag of mint is distilled and the water on it is removed, nearly three liters of hydrosol and one liter of essential oil are steamed!

This oil yield is simply unimaginable on Earth......

Looking at the separated hydrosols and essential oils, Don touched his chin and fell into deep thought.

If the oil yield of Prandal's plants is so high, wouldn't it be possible to use flowers to extract essential oils to make perfumes? This seems to be a way to make money...... [e1]

"My lord, what did you say earlier...... What does it taste like? ”

As soon as Fiona pushed the door open, she was so smoky by the smell that she was black, and she almost fell to the ground.

Tang En's figure flickered, then he held her and said with a smile: "Peppermint oil, the concentration is too high, you are not used to it for a while, wait a minute." ”

With a wave of his hand, the window opened, and a whirlwind swept out of the room with a rich mint fragrance.

"Whew...... I almost thought I was going to die...... Uh......"

Fiona patted her chest, and then realized that something was wrong, and now she was half snuggled in Don's arms, and his hand was also placed in a little unpleasant......

Fiona's heart jumped, did he do it on purpose?

Before Fiona's ** was apprehensive a few times, Don let go of her and smiled, "How do you feel?" ”

Fiona was both lost and annoyed, what the hell is going on with this guy!

If you don't have that meaning, don't tease the lady casually!

"Much better...... You just said, peppermint oil? ”

"yes, that's what we bet."

Don said with a smile, "This is a good thing...... Well, but there's one benefit you won't experience. ”

Looking at Donne's look of regret, Fiona was confused.

One of the benefits that Don said is that he refers to mosquito repellent, peppermint can repel mosquitoes, and the effect is very good, but what makes Don En lucky and regretful is that there is no mosquito here.

"You say this thing can make a lot of money?"

"That's right, this jar is mint hydrosol, I'll give it to you."

Fiona was stunned: "What's the use?" ”

"Hmm...... You can rub it on your body after taking a bath, and you can also pat your face after washing it, which can make your skin softer, clean your skin, remove oil and moisturize, converge pores, and it is also very cool. ”

Tang En has only heard about the benefits of this thing, and he can't say if it really has this function, but women are creatures, everyone understands it, as long as it is possible to become more beautiful, they are willing to try it......

"Really!?"

Fiona was stunned by Donn's bluff, and looked at the large jar of slightly cyan liquid in her hand suspiciously.

What's it called?

Mint hydrosol?

"Of course," Don smiled proudly, "would I lie to you?" ”

So Fiona believed.

"And what's this jar?"

"Peppermint essential oil is also something we make money on."

Don was inspired and asked, "You asked Tina to bring some candy." ”

"Sugar? Well......"

Thankfully, Plantal's sugar is not a luxury, and there is a plant that has a very sweet sap that is dried to make it jaggery, but ...... That's all there is to it.

That's right, although Plandal's sugar is not a luxury, but it is not like the earth, where varieties are everywhere, milk candy, fruit candy, soft candy, hard candy......

What Donn wants to do is to open the door to a new world for the people of Purandal......

After a while, Fiona returned, with Tina behind her holding a jar of jaggery.

"Your lord, the sugar you wanted."

Tina placed the jar beside Don, glanced at Don with a bit of resentment, and went out.

Tang En didn't notice, he took out a little jaggery and tasted it, his brows furrowed slightly, the sugar in this world is more unpalatable than he imagined, after all, it has not been purified.

This is still the sugar in the lord's mansion, and if it is used by civilians, I am afraid the quality is even worse.

Didn't they think about adding water to dissolve and purify?

Don felt incredulous.

Fiona watched Don's movements, and felt unbelievable.

He actually poured a jar of sugar into that pot!? What does he want to do? Boiling soup?

Of course, Don is not cooking soup, since this is jaggery, the first step can only be to remove impurities first, dilute with water, and then filter a few times, the quality is already very good, and then add an appropriate amount of peppermint essential oil, boil until it is viscous, and then pour it into the mold, and the mint is completed!

Needless to say, the detailed steps were not to be mentioned, especially since Don had such a handy tool as magic, and in just half an hour, Don had made Purendal's first jar of mints.

Looking at the crystal clear and round sugar ball with a little green, Don actually felt like he was reincarnated, he almost ate one with tears in his eyes, and then handed one to Fiona: "Try it, I promise you like it." ”

Fiona skeptically took the mint candy into her mouth, and the next moment, she froze.

An indescribable shock!

It was as if a bolt of lightning had pierced her mind, causing Fiona to freeze there.

Obviously, the temperature is already a little hot now, but it is incredible that she actually feels a chill!

"What does it feel?"

Is it sweet? That's true, but it's more important to say that the smell......

"Mint!"

Fiona finally came back to her senses, her eyes lit up: "It turns out that this is the money-making plan you said!?" ”

"That's right."

Don enjoyed the mint candy with a pleasant face, and looked at Fiona with a smile: "Now you say, can this thing make money?" ”

"Yes!"

Fiona had no doubts: "Not only can, but also makes a lot of money!" ”
