Fiona has been smiling all these days. Even when facing Tang En, who had embarrassed her before, she did not look straight, which surprised Tang En very much.

The reason was finally revealed until today when Fiona came to report to him about his work.

"Hilton and Thomas were in great condition in Bein, and it was beyond expectations!"

Fiona said with a gaze: "In the letter, Hilton said that the sales of mint candies and soaps in Beiyin are very popular and have almost become synonymous with our Tang Dynasty Chamber of Commerce. All nobles who have used soap are inseparable from it. Even ordinary civilians will buy a few mint candies to try."

"Oh? That's great," Tang En raised his eyebrows, "This batch of goods has been replaced with new molds, and we have our trademarks, right?"

"Of course! The goods without trademarks are sold locally in the store outside."

Fiona said happily: "Hilton reminded me to urge the workshop to increase production. Next time they come back, they will probably take away a large number of goods."

"Then increase the production."

Tang En said disapprovingly: "The work of those workers is very easy now, even if you add some pressure, it's okay?"

Of course, Fiona knew that Don was not a lord who liked cruel exploitation. The situation in the workshop is indeed as he said. The worker's work is very easy, but...

Fiona smiled bitterly and said, "I think so, but the problem is that the efficiency has not improved."

Tang En was stunned for a moment: "What's going on? They are passive and lazy?"

"This is not, it's just..."

Fiona opened her mouth and said a little hard to speak: "It's just that the workshop is too hot. It's already the midsummer moon. In addition, the workshop is still a completely closed structure. The workers work very hard inside. Although they didn't say it, I went to observe it. It was too stuffy and I had to come out to breathe after a while..."

"I'm dizzy..."

Tang En was speechless: "Why didn't you say such an important thing earlier??"

Fiona was also stunned: "I thought you already know! Didn't you even notice it was getting hotter and hotter?"

"I really didn't find it..."

Tang En smiled embarrassedly. Since he felt a little hot a while ago, he had been maintaining a spell shield on his body, keeping the temperature within a comfortable range. He forgot about this within a few days.

"Actually, it's not very important. Just open a few ventilated windows..."

"Not important? No, it's very important!"

Tang En waved his hand and interrupted her: "If you stay in a stuffy environment for a long time, you will have big problems... By the way, do they rehydrate in time, right?"

"I didn't pay attention to this..."

"No, this problem must be solved as soon as possible."

Tang Enfeng stood up in a hurry, pulled Fiona and ran to the workshop.

The door of the workshop was open, and Tang En removed the magic shield. As soon as he entered the workshop, a heat wave mixed with an unpleasant smell came to his face, making his feet soft and he almost fell to the ground.

However, Fiona has been here a few times, so she has become accustomed to the smell and temperature here.

"No, no!"

Tang En, who was sweating in a cold sweat, opened his magic shield again and breathed a long sigh of relief.

He has always enjoyed air conditioning treatment on earth. After coming to Plandal, he has magic to accompany him. He has never thought about this problem.

Seeing the workers sweating profusely in the workshop... sweating profusely?

Tang En's eyes suddenly fell on the female workers. The thin clothes were completely wet with sweat, and they almost turned into translucent. They were obviously extremely hot, but they did not slackew at all. Instead, they chatted in a low voice and were busy with their work.

Tang En looked straight for a while, subconsciously swallowed, then hurriedly looked away, regained his calm expression, and said in a deep voice: "I was negligent, I will solve this problem."

"How to solve it?...Are you..."

Fiona widened her eyes, remembering that Tang En was an omnipotent powerful mage, maybe there was a way to solve this problem.

Of course, Tang En has a solution to the temperature of the workshop. In fact, a frost magic array can solve this problem, but the problem is that after the frost magic array is constant here, winter comes and it is completely useless. It is simply a waste of resources, so it is not cost-effective.

If there is air conditioner... air conditioner?

Tang En flashed with a flash of spirit and thought about it. After a moment, he clapped his hands: "There is a way!"

Tang En was almost surrounded by the way of thinking on earth. Fortunately, he woke up. In fact, it was very simple to simply create an air conditioner that could discharge air conditioners and heat. All he needed was three simplified small magic arrays.

Tang En did it when he thought of it. In order to let the workshop experience the effect of the air conditioner as soon as possible, he still planned to make a few installations by himself. When Iriya can control her magic steadily in the future, she will slowly let her join in to help.

Considering that it was just a very simple function, Tang En did not use the precious magic metal materials in the package, but went to the blacksmith shop to get some iron ingots. It was enough to use these iron ingots to make the shell and the substrate carrying the magic array. After all, it was just three simplified small magic arrays.

After returning to the room, Tang En immediately began to act. The iron ingot quickly stretched and deformed in front of him, and soon turned into a flat plate. Then Tang En took out some ordinary magic dust and carved three simplified magic arrays on the flat plate according to his idea.

Although it is a simplified magic circle, since the three magic circles share an energy circuit and are superimposed together, the requirements for magic level are very high, and ordinary magicians may only sigh.

"A frost magic array and a flame magic array have weakened its power and simplified its range. Add a weakened hurricane magic array to deliver air to the outside... Well, it should be true!"

Tang En nodded with satisfaction. Since there was no need to pump air or refrigerant to conduct heat, after the assembly of this magical version of the air conditioner was just a rectangular body, and it was very flat. There was only an air outlet open below, and there was a dark grid where the magic crystal was placed and three switches were placed on the side.

That's right, this magical version of the air conditioner has no temperature regulation function, no wind sway function and function, only three switches for cooling, heating and wind control. The set temperature is the benchmark determined by Don't just draw the magic circle with Fiona's feelings. [e1]

The wind control is controlled by Tang En by adjusting the magic power input from the hurricane magic array. The greater the magic input, the greater the wind power.

"This, this thing is amazing!"

Fiona was so shocked that she couldn't speak. Magic has always been the patent of those mysterious magicians. Even if many people know that magic can make people feel more comfortable in the heat or winter, they can only sigh.

But what about Lord Tang En?

Just using some small means to interrupt the high-end monopoly of magic!

As long as you have this thing he calls an air conditioner, even ordinary people can enjoy the convenience and powerful power of magic when they buy it home and install it with magic crystals!

"Lord, that, that..."

After being shocked, Fiona blushed again and said with a little hesitant: "You, can you install one in my room?"

Tang En agreed happily: "Hmm? Of course."

"You are so nice to me-"

Fiona was overjoyed. When she thought that Tang En was a little different to her and the others, she heard Tang En say to herself: "That's true. It's hot, so I'll do some for Tina and the others... By the way, there is also the Iriya family. Elsa's mother is in poor health, so I'll give them one too."

Iriya and Elsa won’t talk about it, but, but even those maids!?

Fiona's eyes widened, and she was so angry that she didn't know what to say.

Is it the same status as those maids in his eyes?

hateful!

Damn it!

This guy, this guy, why do you always play cards without following the norm?

Normally, shouldn’t I be moved, and then I will take advantage of the situation and start an offensive after I speak sweet words?

Why is it so romantic, but he is ruined in just one word!

And it's still a little bit! No! Hesitation!

Is it intentional?

He must have done it on purpose!?

This guy deserves to be single for the rest of his life!!!

"Tsk tsk, magic is really a convenient thing..."

Don't notice Fiona's little emotion, and Tang En, who easily tinkered with a magical version of the air conditioner, couldn't help but sigh. If there was such a power on the earth, I'm afraid that the technology on the earth would not have developed so quickly.

After high-end people mastered and enjoyed the convenience of magic, they would not be able to study basic physics and chemistry knowledge. No wonder the lower-class people here in Plandal were still alive in the feudal society.

After trying the magic air conditioner just made and making sure that there was no problem at all, Tang En immediately made more than a dozen magic air conditioners as he did.

Tang En stood up: "You guys wait until you come back and install it. Now go and install the workshop first. You can't let them continue to work in that environment."

"I see!"

"Hmm? What's wrong? I feel like you're a little absent-minded?"

Fiona felt a bitter breath and looked speechless: "It's nothing! Do the serious business!"

"Yeah, let's go."

Tang En waved his hand and said casually as he walked: "Speaking of this, the midsummer moon is here, this thing is a good product. How much do you think those nobles are willing to spend to buy this?"

Fiona, who was traveling outside the sky, came back to her senses and shuddered: "Yes! Oh my God! Why didn't I expect such an important thing!"

"ah?"

"Lord, you are such a genius!"

Excited Fiona jumped up and kissed Don Eun in the face, then rushed to the study: "You go and install the air conditioner, I want to write a plan for this thing!"

"this……"

Tang En, who was surprised, touched his cheek, was amused and crying, shook his head and went to the workshop on his own.
