Half an hour later, when the two landed again, Martin smiled.

Their location is a depression at this moment.

There are not many plants in the depression, only a few sparse weeds, which appear lonely.

Large patches of black stones emerged from the ground.

Martin almost recognized it at a glance, it was coal!

Even though a large part of it is covered up, the light reflected from the exposed position in the sun shows that the quality of this coal mine should be quite good.

Of course, Martin also knows that the true quality of coal mines cannot be distinguished by the naked eye alone.

However, even if the quality is a little worse, it is an extremely important discovery for him.

Unfortunately, it is a bit far from Farelinburg.

Judging from the map, there is a straight-line distance of more than 70 kilometers.

Moreover, there are no rivers nearby, so it is impossible to rely on water transportation to achieve long-distance transportation.

Therefore, if you want to use these coal mines, you have to build the road here first.

Seeing Martin fiddling with the naked black rocks underground, Tiya couldn't help but smile.

Although I don’t understand what this thing is, it can be seen from Martin’s expression that these black stones must be very important.

After all, after so much trouble, she probably guessed that Martin was looking for important minerals.

You should know that although Martin had a similar smile on the minerals discovered before, he was never as excited as he came this time.

After finding the coal mine, Martin was completely relieved.

Although he had inferred that there were coal mines in this world, before they were found, they were just inferences.

Although wood can also provide heat to the steam engine, the heat generated by combustion is too low, which greatly limits the use range of the steam engine.

In addition, in some special occasions, such as refining copper and iron ore, it is difficult to reach the required temperature with wood as fuel, and it is often impossible to conduct normal drills or obtain high-quality metals.

But coal is different...

This is called industrial food on earth.

Martin wants to realize his path to reform in Faralinburg, and the use of coal undoubtedly plays an important role.

Two days later, Martin, who had checked nearly a hundred locations, was about to embark on his return journey with Tiya.

This time, I discovered three copper and iron ore, two coal mines, as well as aluminum ore, and several heavy metal ore that Martin is not sure about.

These mineral deposits are distributed within a range of 200 kilometers from Faraline.

There is no doubt that this is a very huge gain.

To a large extent, it has exceeded Martin's previous expectations.

...

On Saturday night, in Martin's bedroom.

A sudden twist in the originally calm air, and two figures appeared out of thin air.

These two people were naturally teleported back to Faralin through space, and they could be said to be Martin and Tiya who returned home with a full load.

Martin also confirmed a very important thing: space teleportation can bring people!

At least, with his current ability, he can lead a person.

As for whether you can bring more people, you have to wait until you have the chance to try it later.

Tiya calmly withdrew her hand and said, "Then I'll go back first."

Martin nodded, not leaving her to eat.

He couldn't wait to inform the count of these major discoveries and discuss the next arrangements with him.

More than ten minutes later, Martin came to the manor.

The manor in the night is brightly lit.

When Martin walked into the living room, he saw Mr. Karan in white and Princess Sophia in a pink dress.

In addition, Grace is there too.

The Count was sitting on the sofa, talking with them enthusiastically.

Martin walked into the living room, and the eyes of the three of them lit up.

"Martin, come quickly, we are discussing you!" The Count greeted Martin kindly.

Martin quickly stepped forward to salute Princess Sophia, which was a good gesture.

After all, the identity of His Royal Highness of the Princess is there. Even if the current situation is a bit awkward, the princess is always a princess and she still has to show her respect.

Moreover, he plans to have a big fight with Earl Cross next, and it will be quite good if he can get the support of His Highness the princess.

Therefore, no matter what, it is absolutely impossible to leave a good impression in the other person's heart.

As for the Earl and Mr. Karan, it is naturally not necessary to be so formal.

Everyone's relationship was there, and these red tape seemed to be alienated. Therefore, after Martin greeted Princess Sophia, he nodded slightly to the two of them.

As soon as Martin sat down next to the count, Sophia couldn't wait to ask: "Did you invent the astronomical telescope?"

Martin actually noticed a detail just now. The fluctuations in her power were not very stable, just like the water surface where ripples spread from time to time.

Among the few people present, she was the only one.

And the last time she met, she gave herself a different feeling.

This is...advanced!

Martin, who had seen Glace and Tiya advance, immediately understood, and a strange light flashed in his eyes.

He glanced at Gress again and guessed roughly what was going on.

It seems that the sharp blade that provides her experience points is actually this Princess Sophia!

"I just provided some ideas for Gress. Princess Sophia." Martin said with a smile on his face and was extremely humble.

"Don't be modest, respected Mr. Martin!" Princess Sophia said with her eyes widened, "The cement, steam engine, microscope that Deacon Gress is making... are also the ideas you provide? That is not a little idea. It is the key core of these inventions!"

Her speech was very fast, her voice was crisp, and her eyes were filled with the light of exploration. She was obviously very interested in these things and valued them very much.

Martin was a little surprised and turned his head to look at Gress, asking in surprise: "Has cement been developed successfully?"

Gress nodded, preparing to explain the process, but when he saw Sophia waiting for Martin's answer, he immediately shut up again.

"I also want to learn what Gress is learning!" Sophia glanced at Gress meaningfully and said directly.

Martin smacked his lips and his brows frowned slightly.

Something is a bit troublesome!

Although my students have special identities, they have had contact with each other for a period of time in advance. The two parties have a certain friendship and are relatively easy to get along with.

Glace really likes to study science.

Tiya was saved by herself and wanted to learn about the knowledge of the field of time.

But I only met this princess.

And Martine was really a little resistant.

Because when we first met, Sophia left him a very bad influence.

Martin felt a little disgusted when he was in his thirties.

It is because some of his ideas now need to be supported that he shows such a cautious attitude towards Sofia and is unwilling to offend the other party.

Otherwise, he would not bother to pay attention to the princess and would definitely choose to stay away from him.

"Since the princess is interested, there is no problem. Glads, give the princess a copy of your textbooks."

Martin pondered for a moment, then smiled and said to Gress.

With such an answer, Sophia's face obviously changed for a moment, but she still maintained a smile.

At this time, Mr. Karan, who had been silent on the side, spoke on his own initiative.

"Martin, Sophia has some research on astronomical phenomena and needs knowledge in this area." He looked at Martin, his eyes a little meaningful.

Martin immediately understood that Mr. Karan was reminding himself that Sophia played a crucial role in his promotion ceremony.

Martin rubbed his brows, then turned to Princess Sophia and said, "Since that's the case... Gress and I have some experience in astronomy. Why don't we have time to communicate with each other? How about?"

Princess Sofia smiled and nodded: "When is it more appropriate?"

Although she was still smiling, Martin felt that her smile was not very natural.

"Since it is more appropriate to use astronomical telescopes at night, how about it from 7 to 9 p.m. every night?"

Martin thought for a moment and gave his advice.

Sofia raised her eyebrows, as if she was a little surprised.
