Chapter 51: You're a summoning mage

Horst led everyone through the valley mouth of the Demon Sound Valley with great difficulty, relying on the support of spiritual power, to the black stone, at this time there were still some dark clouds in the sky, and occasionally a few lightning bolts fell, hitting the ground.

"This area is a special area, and I can feel the mysterious power that exists in this place. "Victor's perception was far stronger than Horst's, and he found something that Horth didn't feel.

Horst couldn't perceive what the mysterious power Victor was talking about, but he could guess that it was probably a magnetic field.

Under the action of so many magnetic iron oxide rocks and underground iron ore, some special situations will be formed over time.

For example, a magnetic field far beyond the outside world.

However, this particular power does not seem to be the source of the mysterious sound. Victor's gaze was fixed on the black stone, "Horst, see what to do." ”

"The three of you are elemental mages, go and feel what the substance on this black stone and the powder on the stone walls of the valley are made of. Horst lied, in order not to expose the fact that he was also an elemental mage, "In our hometown, there seems to be such a thing, and it will make strange noises at certain times. ”

With a strange look, the three of Myron did as Horst said.

Suddenly, there was an incredible phenomenon in his eyes.

"This is ......" Myron couldn't believe his mental perception, "this kind of thing is only formed when meteorites fall from the sky." ”

"Ah, I see, I probably know the cause and effect of these phenomena. Nigel's expression was much better, "This kind of thing, under the research of previous people, found that it can record some sounds, but no one knows what the principle is. This kind of thing is relatively rare, I didn't expect there to be so many here, because it is relatively rare, the predecessors have not studied it much, and some have even lost the literature inheritance. ”

Horst heard Nigel's words and continued, "You elemental mages, do you have anything to do with this kind of thing?"

"The composition is the same as that of iron oxide, both are iron and oxygen, but the atomic proportions are different. The ratio of iron atoms to oxygen atoms in iron oxide is two to three, while this substance is three to four. In the case of iron oxide, hydrochloric acid can be used. Myron frowned, "It's not very difficult to extract hydrogen and chlorine from Yuanli to form hydrochloric acid, but I don't know if this three-to-four synthesis of iron and oxygen can be dissolved by hydrochloric acid." ”

Horst roughly knew what Myron meant, and it was true that the ferric tetroxide in the previous life, if it was natural, could not be dissolved by acid, or that acid dissolved more slowly. That's exactly what is happening now. As a mixed component of ferric iron and ferric iron, ferric tetroxide has a special structure and many things to consider.

"Let's try it first, as an Assassin, I'm not as good as the four of you when it comes to material research. Victor admitted his shortcomings, which was a little surprising, at least in the eyes of everyone, Victor was more conceited than just a fool.

"Try it with nitric acid. Horst came up with his own idea, "Prepare a sodium carbonate solution separately for prevention." I've seen about elemental mages in the school library, and I'm familiar with some of the magic that elementals commonly use. ”

Although the elemental mage has just been in contact with it for a short time, or Horst has not been an elemental mage for a long time, he has the memories of his past life, including the content of inorganic chemistry in his previous life.

Myron's face became a little ugly at this time, and he smiled bitterly: "I didn't expect that I would be inferior to you, a summoning mage, as I studied elemental mage." ”

"Nitric acid, known as the all-rounder of acid, many things that ordinary acids cannot dissolve, can be dissolved in nitric acid. I didn't even think that this layer, if dissolved with nitric acid, could do things that hydrochloric acid couldn't. Ian slapped his head, "Let's try it first, although it is more troublesome to extract elements to synthesize nitric acid." ”

When Horst heard this, he couldn't laugh or cry. The mages of this world don't seem to know the classification of acids, but only the effects of acids. Nitric acid can be said to be a universal type of inorganic acid, and the reason why it is said to be a universal type is mainly because nitric acid has properties that ordinary acids do not have.

In the words of Horst's previous life, this non-possessive property is called oxidizing, and thus nitric acid is also called oxidizing acid. Most of the substances that can be dissolved by nitric acid have some degree of reducibility. Moreover, the oxidation of nitric acid increases with the increase of the concentration of nitric acid. What concentrated nitric acid can oxidize, dilute nitric acid cannot.

Ian said, raised his hand, and a ball of water appeared above the palm of his left hand, and his right hand swung left and right twice in a row, and a cloud of reddish-brown gas appeared above the palm of his right hand.

Horst nodded, the preparation of nitric acid in this world is similar to that in previous lives. Nitrogen and oxygen combine to form nitric oxide, which continues to be oxidized by oxygen to form nitrogen dioxide, which is a reddish-brown gas that is now in the sky above Ian's palm.

With a light blue mana fluctuation output, Ian carefully merged the water balloon and nitrogen dioxide mass. In an instant, the reddish-brown gas vanished, leaving only a colorless balloon.

Seeing this, Horst knew that nitric acid had already been prepared. In this world, mana is the energy that prepares matter.

After the reaction of nitrogen dioxide and water, nitric acid and nitric oxide are formed, and this reaction is the main reaction of Horst to prepare nitric acid in his previous life. The meaning of Ian's right hand move is to decompose the generated nitric oxide into elemental elements with mana and return to the Heaven and Earth Yuan Qi.

"Let's try it with those things on the rock walls of the valley. Myron was a little unsure, "After all, the research of this kind of thing is not very clear in the past. ”

When Horst heard this, he thought it was a little funny. Ferric oxide, as a mixture of ferric iron and ferric iron, in which ferric iron has strong reducing properties, nitric acid has strong oxidation, which is like a positive and a negative, positive and negative attract, how can it not react?

However, Horst didn't stop Ian, and he couldn't have said that this thing had been decided in another world.

As Horst had predicted, the black substance on the rocky walls of the valley dissolved in it as soon as it encountered nitric acid.

"You pull the water out of the water balloon until it's dry. Horst had a whim.

Ian did so, and a strange phenomenon occurred, as the water balloon gradually darkened in color as the water glass in the water ball was withdrawn. Eventually, all that remained was a dark purple solid.

"It's so beautiful!" Salene, as a girl, was a little ecstatic.

"Is this ferric nitrate?" Ian's eyes couldn't hide his frenzy, "This is the finest trinket in the magic jewel!"

Horst was stunned, but he didn't know about it, he just wanted to see what ferric nitrate looked like in an anhydrous state, but he didn't expect this to happen.

"Boy, it seems that you, a summoning mage, have far more attainments in elemental mages than those of us who study elemental mages, and you are very different as a summoning mage!" Nigel smiled bitterly, as a third-order elemental mage, they didn't think of these things, but Horst, a summoning mage, knew more than them.

Horst was helpless, it was impossible to tell these people the truth. He had no choice but to continue to lie: "I just read a lot of books in the college library, and your level is much higher than mine." ”

"Since there is a result, you better quickly solve this black stone. Then, in the same way, clean up the rock walls of these valleys. "Victor naturally knew that the mysterious sound was made by the black stone in front of him, and all he had to do was destroy the black stone in front of him.

As long as the black stone is destroyed, it means that the army behind will be able to pass through the Valley of Demonic Sound. Even if there is still a special attack attached to the mysterious sound, it will be able to survive with the special enchantment created by the four warriors.

Two of the three elemental mages had prepared a large amount of nitric acid according to the conclusion just now, preparing to completely dissolve the blackstone.

The rest was prepared with a sodium carbonate solution, an alkaline solution that neutralizes accidental spills of nitric acid while also eliminating the effects of the residual nitric acid liquid.

After all, nitric acid, as an acid, in addition to oxidizing some substances that are difficult to be dissolved by non-oxidizing acids by virtue of its oxidation, also has the properties of ordinary acids, and acid-base neutralization reactions occur.

The effort to dissolve the black stone was not very long, and it was also very smooth, and as the black stone dissolved, everyone obviously felt that the special sound waves in the mysterious sound gradually disappeared, so that in the end there was no at all. But the mysterious voice remains, only much less than before. Fortunately, the special sound waves disappeared, and everyone's spirits recovered, and they no longer used their mental power to resist.

In fact, it is no wonder that this area has been determined by Horst to be the site of the meteorite fall thousands of years ago, not to mention that there are a large number of iron ores buried here, of which the iron tetroxide can be described as countless, but it seems that only this black stone recorded the infrasound waves produced by the meteorite explosion that year, all of which seems to be a coincidence. Or rather, the luck of the advance team is better.

Myron and the others extracted the water from the dissolved black stone, resulting in a large dark purple ferric nitrate crystal.

"Is there a space-tied magic container?" Myron quipped, "take it back and sell it to the auction house, and we'll split the spoils when the time comes." ”

"I have a space ring here, but it's not very large, so I don't know if I can hold such a large piece of magic jewelry. Apparently Sharlene also has some research on jewelry, "You keep some for me, and I'll make some jewelry myself." ”

"Alright, alright, you first clear the black substance on both sides of the valley, if it is clear or not, forget it. Victor also took out a space ring, "Give me a little, I'm going to give it to my girlfriend." ”

Horst was a little speechless, although iron nitrate was something that elemental mages could synthesize through the extraction of elements. However, magic jewelry is not something that anyone can make, it is the preserve of craftsmen.

"Let's inform Septon of them. ”
