Chapter 50: The Mystery (Part II)

When I got closer, the black stone was angular and spherical, resembling marbles. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

"It's ......" Horst touched the beads with his hand, and they were hard, the first sensation. Icy cold, or rather, doesn't have any sense of temperature.

Something flashed through my mind, and I looked at the black substance on the stone wall.

"Ahh

A feeling of paralysis spread throughout the body, and suddenly, a large number of dark clouds gathered in the sky, and a lightning bolt struck a certain part of the stone wall of the valley.

Enduring the severe pain, Horst immediately moved away from the black stone, and it took a moment to recover.

"That's right, that's it. Horst, relieved, sat cross-legged on a weed, meditating, some knowledge of his past life flashing in his mind.

Regarding the formation of the Phantom Forest, it is necessary to trace back to the meteorite thousands of years ago, and it was the arrival of that meteorite that caused mysterious voices to appear in this area.

If, at that time, there was some kind of ore in this area, it was that meteorite explosion that caused the qualitative change of the ore, which led to a series of subsequent worlds, it seems that something can explain it.

Horst guessed in his mind that the effect of the Contemplation Necklace was extraordinary, and he quickly calmed down and thought carefully about this series of things.

He didn't find any trace of the demonic beast in the Demon Sound Valley, which means that there is no demonic beast here, and the sound of the beast's roar in the second half of the night was not emitted by the demonic beast.

Scraped some black powder off the stone wall, and got a small handful of reddish-brown soil from the ground.

Put the two things in your hands and compare them carefully. It seems that there is a big difference, but when you look at it, it seems that it feels very similar.

Horst concentrated his spirit, his mind perceiving the two masses of matter. This is how elemental mages perform magic or analyze things.

Even when the emergency conscription order was issued, Horst still did not stop practicing in the barracks.

One of these practices is to learn some of the basics of elemental mages, including the mental perception and analysis of unknown substances.

Summoning mages, who are only responsible for spatial configuration, summon spatial molecular models of organic compounds, and then use spirit pets as life givers to form unique summoned beasts.

Elemental mages are different, they need the cooperation of elemental affinity, carry out mind perception, and perform elemental analysis of unknown matter. It is equivalent to the various analytical methods learned in inorganic chemistry in previous lives.

Horst's abilities as an elemental mage are still basic, but for a chemical genius, whether it is organic chemistry or inorganic chemistry, there seems to be nothing difficult.

What's more, the material elements in this world are the same as in the previous life, and the magical elements are these material elements. To be precise, the magic in this world is actually based on the application of the elements based on the Yuan Force of Heaven and Earth.

Sensing his mind, Horst conjured up the material structure in his mind.

The reddish-brown substance shows a ratio of two to three elemental atoms, and the black substance shows a three-to-four ratio of elemental atoms. But, this is not absolute.

Horst also found that both the black powder scraped from the stone wall and the reddish-brown substance of the valley soil had the same elemental composition and belonged to the mixture.

The mental power is concentrated again, and the perception of the mind continues to strengthen.

A strong electric current suddenly flashed through his mind, and a tingling sensation came.

"Ah, that's it. This time Horst looked a little excited.

At the moment when the current appeared, Horst completely figured out the composition of one of the elements through mental perception.

In the previous life, the twenty-sixth element on the periodic table - iron, this world is also called iron, but there is no periodic table. Even, in this world, many elements have not yet been discovered, only exist in people's experience summary, and have not really been extracted.

Horst saw a nucleus surrounded by an element of twenty-six electrons, and that was iron.

In this way, if the black substance is in a ratio of three to four, it should be ferric oxide, while the reddish-brown soil is in a ratio of two to three, which should be ferric oxide, that is, iron oxide, which is the main component of rust.

Of these two substances, ferric oxide is also known as magnetic iron oxide, and the reason for this is that ferric oxide can be used as a magnetic material in certain states. In previous lives, this was extremely widely used.

In fact, to explain it according to the theory of the previous life, iron is a metallic element, and the common valence states are bivalent and trivalent. Ferric oxide can be seen as a mixture of ferric and ferric iron. At the same time, due to the magnetic properties of ferric tetroxide, it can be used to make recording materials.

It is well known that magnetic substances are capable of recording mechanical waves at certain frequencies.

"In fact, they should be called mixtures of ferrites. A smile appeared at the corner of Horst's mouth, and the image kept flashing in his mind, "Since ferric tetroxide is magnetic and can be used for recording, I think I seem to have uncovered the mystery of the mysterious sound."

At this time, Horst connected all his thoughts together to form a picture, and he was a little speechless for a moment.

One day, thousands of years ago, a meteorite whistled down from the sky.

The meteorite landed, and the explosion produced extremely high temperatures, and at the same time formed an extremely terrifying sound wave - infrasound. There is no concept of infrasound in this world, but Horst had it in his previous life.

Based on the effects of the past two days, the symptoms are very similar to those caused by infrasound, especially now that the geological composition of the area has been determined, so Horst is firmly convinced that the mysterious sound is accompanied by infrasound.

And the place where the meteorite exploded should be the current Demon Sound Valley.

Coincidentally, there is a large amount of iron ore buried under the Valley of Demonic Sound. At the moment of the meteorite explosion, a large amount of energy is released, resulting in extremely high temperatures and pressures.

Under the combined effect of extremely high temperature and pressure, iron ore is first melted to form aggregates of iron elements, that is, converted into pure iron. Then, with the continuous action of high temperature and high pressure, pure iron interacts with certain components in the air, especially oxygen, to form ferric tetroxide.

Ferrotetraoxide, on the other hand, is magnetic, and at the moment of explosion, the infrasound waves generated are continuously recorded, that is, recorded.

After that, the recording will be played out every once in a while due to certain factors. To this day, this is why the Forest of Illusions has periods of relative safety every once in a while.

As for the lightning just now, Horst guessed that due to the existence of iron ore here, especially the meteorite explosion at the beginning, a part of pure iron was generated and buried underground. With the propagation of infrasound waves in the air, air molecules absorb energy and collide, and there may be a transfer of electric charge in the collision process, coupled with the frictional contact between Horst's own clothes and the air, forming static electricity, and there is a similar existence of cumulonimbus clouds in the sky, and the combination of the three also produces thunder and lightning.

Infrasound waves are extremely dangerous for people, especially for mental damage.

The whole process is roughly like this, all the mysteries are solved, and it comes from a large explosion caused by an extraterrestrial meteorite here thousands of years ago.

With that in mind, Horst knew what to do with it.

Continuing to look at the black stone, the orbs on it, Horst perceived with his mind, a substance similar to pure iron, or rather, it was the product of a meteorite explosion, and there may have been other elements mixed to form some kind of alloy.

The Necklace of Contemplation continued, and now that the mystery had been solved, Horst decided to return to the team, after all, there was still something to do as a member of the advance team.

Walking out of the Valley of Demonic Sound, it was already noon, and Horst saw Victor and the others.

"How's it going?" Victor's expression was a little distracted, and it was obvious that he was in a state of extreme anxiety. After all, he is responsible for the number ten of the advance team, and he is responsible for the follow-up army of 50,000.

"I think I'll have a way to deal with it. Horst's face was relatively relaxed, and solving the mystery was the confidence for him to say such things, "There are no demonic beasts in the Demon Sound Valley, so there is no need to worry." ”

"Only ......" Horst paused deliberately, he didn't know how to say it, although some of the things in it involved elemental mages, but Horst didn't plan to announce that he had the ability to be an elemental mage.

Everything must wait until it comes to fruition, not to mention, you have mastered the abilities and theories that this world is not known to the world. It is with the help of these abilities and theories that Horst has the possibility to go further and further on the path of mage.

At least, Horst now has no way to explain the theory he has mastered, because he only has a first-order seventh-level mana level now, which is no different from a novice in online games in his previous life in the eyes of others.

"Only what?" said Salene, who looked calm, but the anxiety in her eyes could still be felt by Horst.

"Forget it, I think you'd better go in with me. Horst's idea was simple, the black stone and the ferric tetroxide on the stone walls on either side of the valley were the source of the mysterious sound.

In fact, that black stone is also made up of most of ferric tetroxide.

The infrasound waves attached to the mysterious sound came from the black stone. In other words, if you solve that black stone, the problem will basically be solved.

The Phantom Forest, which has lasted for thousands of years, has solved the mysterious and undetectable problem.

"Well, maybe you really found something in there. ”

Hearing this, Horst instantly felt that he could not answer.
