The Lord of Another World: All Wasted at the Beginning, and He Made His Fortune by Taking in the Fem

"Speaking of which, Teacher Jiangyue, do you know anything about geothermal energy here?"

"That was the main research topic of my student, the little girl who later became the Duchess. She had always wanted to find a substitute for the magic source stone, and the geothermal energy facility here should be the result of her research."

"Why did that lady die so early?"

While strolling on the warm and bright streets, Aarons asked about things related to Duke Ophelia.

Jiangyue used to be the Duchess's teacher, so she had some understanding of that man - but that was basically several years ago.

"I don't know the truth, but there are rumors that the Duchess was given a slow-acting poison by an outsider, and when she was discovered, she was already beyond help, so she died soon after."

Considering the sensitive identity of the Duchess, everyone is a suspect. The Duke of Ophelia did not remarry after his wife's death, probably because he had not yet found out the truth.

But no matter what, the Duchess did leave Duke Ophelia a legacy of inestimable value.

"Then what exactly is this geothermal energy they use, Teacher Jiangyue, do you know?"

"I haven't had any contact with this place for a long time, so I haven't seen any samples. Marquis, are you planning to let me take this opportunity to analyze their technology?"

"That's about it - Dark Wing, is there a place in the city where we can directly observe the geothermal system working?"

After contacting No. 1 who was collecting intelligence in the city, Aarons soon received a definite reply.

[There is a demonstration facility open to the public in the central area of ​​the city. You can go there and take a look. ]

Duke Oufei does not seem to intend to conceal the technology he uses, perhaps because these resources can only be produced in specific environments.

Although Aarons is not proficient in technology, he still has some basic common sense.

"By the way, Marquis, I have completed and deployed part of the things you asked me to develop. If you have to participate in the battle later, you can summon those things from the White Bird to support you."

What Jiang Yue was talking about was the mind-controlled drone that Aarons had previously requested to be made, which could cast simple magic spells. Although the combat power of a single drone was not very strong, it was able to be controlled in large numbers at the same time.

According to previous tests, Aarons' current mental power can precisely control about 300 drones at the same time. If he gives up the control accuracy, this number can be doubled.

After releasing magic, these things only need to return for a simple magic replenishment before they can attack again.

"Let's wait until the situation is really critical. Let's go to the central area first."

The city seemed quite peaceful at the moment, and Duke Ophir did not seem to be in the city, so Aarons did not think he would encounter any crisis that was difficult to deal with.

Moreover, he is protected by Jiang Yue and Mo Qianyun, and the white birds in the sky are also monitoring the situation in the city. Even if there is a problem, Aarons can avoid danger in the first place.

……

However, when the three arrived at the tourist area where the geothermal facilities had been on public demonstration, they were still amazed by the scene.

A machine that looks like a waterwheel constantly pumps out some kind of boiling liquid from the ground and transports it to another machine.

As the machine absorbed the heat, a completely unmagical device was activated - it lit up special light bulbs and heated a demonstration stove nearby.

"Such a strong heat... I need to observe it closely, please wait a moment."

The sage was of course very curious about the technology used here, so she immediately came over alone. Mo Qianyun stood beside Aarons, alert to any abnormalities that might occur around him.

However, even after Jiangyue walked around the equipment several times and came back, Aarons did not see any suspicious people or things.

"Well, how should I put it... Marquis, the energy they use is not spiritual power or magic power, but I guess it has something to do with the magic source stone."

"Isn't it the state where it is heated to a fluid state?"

"No, it feels like... these things are what the planet's power looked like before it condensed into magic source stone. These things should have flowed along the earth veins to various places, and then after cooling and solidifying underground, they became the magic source stone we are familiar with."

Magic source stone is the energy that the planet provides for the life that lives on it. This power has enabled human civilization to develop rapidly - but until now, humans have not fully understood its nature.

The magic sage who established the application technology of magic source stone now realizes the narrowness of his own understanding.

"These things are just pure heat in the earth veins, and they don't have the properties of spiritual energy. As for why they can be transformed into magic source stones... I need to get some samples."

"Then let's find a copy and study it. Dark Wing, can you get a sample of the energy used by this city?"

[Got it, boss. We'll get it done as soon as possible. ]

"Let Dark Wing collect the samples, and we'll look elsewhere."

Extracting pure energy from the earth as energy to drive various devices is very similar to the world in Aarons' previous life.

However, in this magical world, such energy is not as convenient as magic.

"This city's lighting and heating do not use magic... This saves some of the consumption of magic source stones."

"Compared to these, I am actually more concerned about what the Duke wants to do."

Since Duke Oufei has chosen to widely deploy this energy and technology that goes against common sense, he must have some ulterior motive.

Since the whereabouts of the Third Prince is currently unknown, Aarons does not dare to act rashly - if something happens to the Third Prince and he cannot fulfill his promise, he will have no choice but to flee from the empire.

If that happens, my prestige will be greatly reduced...so I have to avoid that situation at all costs.

[Boss, the sample has been obtained, and my team is sending it back to White Bird.]

"So soon? Thanks."

[In addition, we have obtained a key piece of information. Duke Oufei is collecting some special materials from major cities. We don't know what it is, but it has a nickname called "Flame Core". ]

This is indeed important information.

The Dark Wing Team found the key clues in such a short time, which gave Aarons a clear breakthrough for his next action.

"Teacher Jiangyue, do you know something called 'flame core'?"

"...Dia mentioned this in her past research reports, but I don't know what it is exactly. Marquis, are we going to investigate this?"

"Yes, Duke Oufei is collecting this kind of stuff everywhere, which may be directly related to his plan."

Now that you have a goal, of course you have to take action.

However, Aarons always felt that Duke Oufei did not seem to be very interested in the future of this country.
