The emergence of the punching machine, the cutting machine and the grinding machine could certainly improve efficiency, but it was still not enough to fundamentally change the world.
After all, it was still impossible to achieve large-scale industrial production.
The biggest credit for the emergence of these three machines was still Tang En, because the core was the magic created by Tang En.
There was a constant levitation spell on the hammer, a gravity amplification magic array that could determine the conditions, and an adjustable whirlwind magic array that could stabilize the cutting knife and grinding wheel …
Other than Tang En, which mage would do these things?
Those who were willing to do it did not have the ability, and those who were capable would not do it, so these things could only be done by Tang En.
The time when the era would truly change was when all mages were willing to do these universal magic applications.
"You guys produce those farming tools in these two days, and then I have other things to give you guys to do."
Tang En laughed. "Since you said you want to follow me, don't blame me for making you too tired. Let me tell you in advance, your recent tasks are very important."
"No problem, big brother, don't worry!"
Brian patted his chest and promised, "You will definitely complete the mission beautifully."
The originally heavy and boring task became unusually easy with the addition of these three machines. Brian and the others could certainly complete it easily.
Edgar certainly would not say anything. Not to mention that this was the lord's order, just the value of the Auguin ingot that Tang En gave them was enough to let them work for more than ten years.
"Well, I'll come back the day after tomorrow. I hope you can complete all the work … Oh, give me some iron ingots."
When Tang En left, Brian and Edgar had already begun to immerse themselves in the fiery work.
What was Tang En going to do? Of course, he was going back to study the mint!
He still had a bet with Fiona!
After returning to the bedroom, Tang En shook his head inwardly.
"It's not good to not have an alchemy laboratory. A lot of experiments may need one in the future. I'd better find time to build one."
Although he would find time to build one, when was still a problem because Ellington could not get many tools and materials for the alchemy laboratory. If he wanted to build it as soon as possible, besides waiting for Ellington's caravan to bring it over, he could only consider going to other cities to buy it himself.
The matter of the alchemy laboratory was temporarily put aside. Tang En picked up a piece of mint and pondered.
Apart from being edible, mint's value was based on its essential oil. Therefore, if mint wanted to exert its economic value, there must be a set of low-cost and efficient essential oil extraction methods.
As far as Tang En knew, only the distillation condensation method belonged to this type of method.
Whether it was the distiller, the condenser, or the separation of water and essential oils, there was not much technical content. The biggest difference between distillation methods was the water distillation method, the water distillation method, and the steam distillation method. But for Tang En, there was no difference for the time being.
"Let's try it first."
After Tang En roughly recalled the structure of the distiller and condenser, he began to work on them.
The iron ingot brought back from Edgar was quickly stretched and twisted under the effect of magic. Soon, it became a hollow distillation device, and the condensation tube on the other side was also smoothly formed.
"The glass one looks better."
Tang En pursed his lips. The iron distillation device and condensation tube were of course not easy to use on Earth, but it did not matter to Tang En. Under the effect of magic, both heating and condensation were very simple and convenient.
He drew some water from the air and directed it into the distillation device. He added an appropriate amount of mint leaves, connected the condensation tube to the container, and directly began to heat it.
The magic circle under the distillation device steadily emitted heat, and soon the water inside began to boil. At this time, Tang En activated the magic circle covering the condensation tube. The ice magic circle was a variant of the water magic circle. Under Tang En's adjustment, it steadily and persistently lowered the temperature. The condensation effect was dozens of times better than the condensation equipment on Earth.
Under the personal operation of Tang En, this simple set of equipment only took a few minutes to produce a semi-finished product.
Tang En smelled the fragrance in the jar and raised his eyebrows. "The oil yield is so high?"
The quality of the mint here was unexpectedly good. After the bag of mint was distilled and the water on top was removed, nearly three liters of pure extract and one liter of essential oil were distilled out!
This kind of oil yield was simply unimaginable on Earth.
Looking at the separated extract and essential oil, Tang En touched his chin and fell into deep thought.
If the oil yield of plants in Prandal was so high, then wouldn't it be rich to extract essential oil from flowers to make perfume? This also seemed to be a way to make money …
"My Lord, what did you say before … What is the smell?"
Fiona had just opened the door when she was hit by the smell. Her vision turned black and she almost fell to the ground.
Tang En's body swayed and he supported her with a smile. "Mint oil. The concentration is too high. You can't get used to it for a while. Wait a moment."
Tang En waved his hand and the window opened. A whirlwind rushed out of the room with the rich mint fragrance.
"Phew … I almost thought I was going to die … Uh …"
Fiona patted her chest and then found that something was wrong. At this moment, half of her body was nestled in Tang En's arms, and his hand was placed on a bad place …
Fiona's heart skipped a beat. Did he do it on purpose?
Before Fiona's body could become nervous, Tang En let go of her and smiled. "How do you feel?"
Fiona's heart was lost and annoyed. What the hell is wrong with this guy!
If you don't have that intention, don't tease a lady!
"Much better … You just said, mint oil?"
"Yes, it's the thing we bet on."
Tang En said with a smile. "This is a good thing … Well, but you won't be able to experience one of its benefits."
Looking at Tang En's regretful face, Fiona was confused.
One of the benefits that Tang En mentioned was the repellent of mosquitoes. Mint could repel mosquitoes, and the effect was very good. But what made Tang En both lucky and regretful was that there were no such creatures as mosquitoes in Prandal.
"You said that this thing can make a lot of money?"
"Yes, here, this is a jar of mint extract. It's for you."
Fiona was confused. "What's the use of it?"
"Well … You can wipe it on your body after taking a shower. You can also pat your face after washing it. It can make your skin softer, clean it, remove oil, moisturize, close your pores, and it's very cooling. Oh right, if you have small pimples, you can also wipe them."
Tang En had only heard of the benefits of the extract, and he could not say for sure whether it really had such an effect. However, women were creatures, and everyone knew that as long as there was a chance to become more beautiful, they would be willing to try it.
"Really!?"
Fiona was stunned by Tang En's words. She looked at the big jar of slightly green liquid in her hand suspiciously.
What was it called?
Mint extract?
"Of course," Tang En smiled proudly. "Would I lie to you?"
So, Fiona believed him.
"Then what is this jar?"
"Mint essential oil. It's also something we can make money from."
Tang En had an idea and asked, "Ask Tina to send some sugar over."
"Sugar? Okay … "
Fortunately, Prandal sugar was not a luxury item. There was a very sweet plant juice here. After drying it, it would become coarse sugar, but … that was it.
Yes, although Prandal sugar was not a luxury item, it was not like on Earth where there were all kinds of sugar, milk candy, fruit candy, soft candy, and hard candy …
What Tang En wanted to do was to open the door to a new world for the people of Prandal …
After a while, Fiona came back. Tina was behind her with a jar of coarse sugar in her hands.
"My Lord, here's the sugar you wanted."
Tina put the jar beside Tang En. She looked at Tang En with a little resentment and left.
Tang En did not notice. He took out a bit of coarse sugar and tasted it. He frowned slightly. The sugar in this world tasted worse than expected. After all, it was not purified.
This was the sugar in the Lord's Mansion. If it was used by civilians, the quality would be worse.
Did they not think of adding water to dissolve it and purify it?
Tang En felt that it was inconceivable.
Fiona looked at Tang En's actions and also felt that it was inconceivable.
He actually poured a jar of sugar into that pot!? What was he doing? Making soup?
Of course, Tang En was not making soup. Since it was coarse sugar, the first step was to remove the impurities, dilute it with water, and filter it a few times. The quality was already very good. Then, he added an appropriate amount of peppermint essential oil and boiled it until it was sticky. Then, he poured it into the mold. Clang, clang, clang. The peppermint candy was done!
The detailed steps were needless to say, especially when Tang En had such a convenient tool like magic. In just half an hour, Tang En made the first Prandal pot of peppermint candy.
Looking at the crystal clear round sugar balls with a little bit of green, Tang En felt as if he was reincarnated. He ate one with tears in his eyes and then handed one to Fiona. "Try it. I guarantee you'll like it."
Fiona put the peppermint candy in her mouth with suspicion. Then, the next moment, she was stunned.
An indescribable impact!
It was as if a bolt of lightning had cut through her mind, making Fiona's whole body stiffen.
Even though the temperature was already a little hot, she still felt a sense of coolness!
"What does it feel like?"
It's sweet? That's not wrong, but more importantly, the taste …
"Peppermint!"
Fiona finally came back to her senses, her eyes shining. "So, this is the money-making plan you were talking about!?"
"That's right."
Tang En's face was contented as he enjoyed the taste of the peppermint candy. He looked at Fiona with a smile. "Now, tell me, can this thing make money?"
"Yes!"
Fiona had no doubt. "Not only can it, but it can also make a lot of money!"
