Although she didn't want to admit it, the comments about Andre Gothales that Kasena had heard along the way were a vicious "spell" that followed her all the way!

Why is it that the slightest bit of fun in this town can be associated with that annoying guy?

Tasting the cold and sweet prickly pear shaved ice, Casena was swaying on the swing next to the ice shop like a little girl, and her mood was like the weather in the stormy sea, and the clouds dissipated in an instant and became happy. Some fairies who were as happy as she were around her swayed slowly back and forth, and the cool wind brushed the young lady's exposed arms like the soft little hands of the ice fairies, and Kassena, who was in a good mood, couldn't help but laugh out loud.

"Thank you for the shaved ice, it's a very special experience!, but why did you choose to leave Garlanord and open a freezing shop here?" Cassena asked, clapping her hands and jumping off the swing, curiously asking herself before leaving.

"Of course, it's because His Highness Andre promised that there are so many delicious and fun things here!" the goblins replied with a grin, "Even the idea of the freezing shop was proposed by His Highness!"

Kassena, who had been looking at ease, suddenly felt that she was really asking herself for this more question - is this beautiful and bustling town completely shrouded in the shadow of that guy!?

She seemed to have seen an evil face with black eyes hiding behind the clouds on the horizon, sinister grinning!

There may be no way to avoid the problems that should be faced, and the journey that should have been extremely enjoyable seems to have been completely ruined by that hateful guy from the demon world!

Why did you make that promise to that guy without considering the consequences!?Is it just like my brother and sister said, as soon as I drink, I will make a mistake!?

It doesn't seem like a way to wander like this any longer, and although Andrari is prosperous and happy, she has basically visited it all the past few days...... Although everyone here had been fooled by that guy, Kasena still thought that the so-called wisdom of the demons was just a little cleverness like those cunning humans!

After all, he was the only child of the abyss who had appeared in Galandia in the past few hundred years, and there was nothing else to do anyway...... Let yourself expose that guy's ridiculous disguise of seeming wisdom in that guy's "class"!

So Kasena made a decision that she regretted for years, and the young lady of Chongnuo was devoid of being alone for three years for blatantly violating the rules of the stormy sea.

......

"The 'Orri' course is a new subject that His Highness has just decided to offer, and the first Orian class just now is the same as what we will listen to next. His Highness has made it mandatory for each instructor to take at least two lessons of the same course, so that none of the students who have conflicts with other courses will miss out on those valuable knowledge. ”

On the way to the classroom, Illion introduced the various details of Valhalla to Kasena as he walked, "Actually, you can just go and listen to the 'Orist' course taught by His Highness alone, you should have mastered this part of life science about the laws of nature very thoroughly." ”

"Aren't you the same, Your Highness Irrien, and as the daughter of the Earth Goddess, you don't know the mysteries of this?, but many of Enril's views have really opened my eyes once again. The young lady from the stormy sea summed up the harvest very seriously.

"Yes, the part about the invasion of alien species......" As soon as the academic questions were discussed, the beautiful elf princess immediately became enthusiastic, and lost her usual quiet and indifferent appearance.

"Isn't the head of this school a typical invasive alien species?"

"What nonsense are you talking about, Kasanna, Your Highness Andre has always followed the moral traditions of our elves and dwarves, but he has never acted recklessly. At this point, even Illion himself blushed - the first time she saw the Children of the Abyss, that fellow had almost ruined his own reputation for innocence.

It's just that the two ladies didn't know that the person who first came up with the term "alien species" was actually the one they were talking about.

"I hope it's true......" Fortunately, Kasena, who was still immersed in the brainstorming and had not jumped out, did not notice the subtle face of her companion.

Two beautiful ladies who were thinking about something in their hearts, and the young dwarf who was walking across from each other, who were also troubled by some problem and neglected their surroundings, bumped into each other at the door of the classroom of Orlie's class.

"I'm so sorry...... Offended His Royal Highness Iryan, and this beautiful lady. "The dwarf who came back to his senses was busy and apologized.

"It's okay, Hallendiel-san, it's just a small unintentional move...... The one next to me is Lady Kasena Hoshiha from the Stormy Sea. Illion politely introduced his companions to the hill dwarves from the north.

"I see! I'm still wondering what a powerful female warrior could have completely suppressed the heavyweight runner-up Passas, and it turned out to be a lady from the stormy sea......!

"You are the son of the hills of the Far Mountain Clan, is there any very interesting and complicated question in the lecture of the son of the abyss?"

"I've seen the Venerable Lady Star Feather...... That's right, ma'am. According to the new classification proposed by His Highness, ice, which seems to us to be more closely related to water, actually contains a large part of the properties of earth. I was just thinking about whether the excellent ice magicians in our Alpine Dwarf lineage have some necessary connection with this view of His Highness......"

"Ice is obviously of the same origin as water, why is it associated with the earth element? This is just the son of the abyss opening a river!?"

Kasena retorted with a slight disdain, and even Princess Illion, who was beside her, looked puzzled.

"Not such a lady...... It's because my mouth is too stupid, you two must have come to listen to His Highness's new 'Orri' class, right? I think you will definitely have the same great gain as I do after listening to it!"

......

As Cassena sat down in the crowded classroom with suspicion, André Gosareth's first words on the podium succinctly and clearly resolved her and the elven princess's doubts.

"An unknown scholar once divided the properties of known matter in the real world into four categories, namely the wind element for the 'gaseous state', the water element for the 'liquid state', the earth element for the 'solid' state, and the fire element for the unstable 'changing state'. ”

It turns out that this is the so-called ice contains some of the earth's elemental properties, and if it is classified by the so-called "form", ice and rock can indeed be classified as "solid", Kasena suddenly understood.

"The first thing we want to talk about today is the connection between these four 'material elements'......"

"It's a normal piece of ice. Andrei on the stage placed the ice cubes in the graduated crystal glasses, and then placed the crystal glasses on top of the already lit oil lamps for experiments.

After a while, the ice melted, and the Children of the Abyss motioned to the students in the front row to note the height of the "ice water" in the crystal cup, and then continued to heat until it boiled......

Ignoring the gurgling "beaker", André moved on to other, more complicated-looking experimental instruments - he placed an ordinary piece of wood in a crucible commonly used by blacksmiths, covered it with a crystal lid, and sealed it with pig iron melted by magical flames. The lid of the crystal is connected to a transparent precious crystal tube, several sections of which are connected by a "rubber" hose from the Van Jia Kingdom, and the other end leads to a crystal trough filled with clean water.

In the trough is a crystal jar that is completely immersed in water, and the inverted jar is also filled with ordinary water.

"What the hell is this guy doing?" Casena in the seat asked the elf princess with a frown.

"I don't know...... However, I heard that those crystal vessels took a lot of effort from craftsmen, so this should be a very important experiment. ”

The wood in the crucible gradually rose faintly as the raging furnace began to operate, and then as the wood became more and more charred, the flames disappeared abruptly, but the process of the wood turning black continued, as if there was an invisible nameless fire burning the wood in the crucible.

It was only at this time that Andrei stretched out the crystal tubes that had been bubbling out of the sink under the inverted crystal jars, and the bubbles that kept coming out of those pipes were collected into the inverted jars little by little.

"Your Highness, this experiment is similar to the process of coking coal, right?" asked Andre after receiving permission.

"That's right, Bud, but what I want to show you today is not the process of coal coking, but some more wonderful changes. ”

At this time, the "ice water" that had been boiling on the other side had basically dried up, so Andrei turned the students' attention to the beaker with only a little water left.

"This is what I want to show you, the most typical transformation between elemental forms. Water is a representative substance that shows this typical change, from 'solid' ice, to 'liquid', to 'gas', to water vapor. The three forms of water are linked to what we call heat or 'temperature', a data used to describe the 'hot and cold' of an object, which may not be well known to all of you, but it has long been introduced into Andrarui's winemaking, essential oil extraction and metallurgy. Do you have any questions about the changes between forms of matter?"

"Your Highness, can all matter in the world be transformed between these three forms through changes in temperature?"

Although the critical point of 'liquefaction' and 'solidification' of the 'gas elements' as we know it is impossible to observe it most of the time, this does not prevent us from hypothetizing that it is only because their liquefaction and solidification temperatures are so low that they do not exist in the natural world. ”

Although the phenomenon of gas liquefaction and even solidification is not an unprovable problem in the other world, for things that he cannot prove with facts at present, Andrei simply makes assumptions to guide his students.

"And what about rocks and metals, Your Highness, is it possible for them to transform into 'gas elementals' at extremely high temperatures that mortals can't predict?"

"Although most metals liquefied in a state that looks very different from the water we normally see, anyone who knows alchemy will know that one of the materials of alchemists is a liquid called 'mercury'. Although it is liquid, it has the characteristics of most metals. As far as I know, it is completely vaporizable...... However, this liquid metal is highly toxic after vaporization, please don't try it lightly!"

This slightly unpopular knowledge elicited suppressed exclamations from the students, and before they could digest the conclusion, the Children of the Abyss drew their attention to the experiment.

"What I want you to witness with me is the connection between the three elements of 'air, water, and earth' and 'fire'......"

Using his spiritual power to summon a small flame like a candle from his left hand, Andre directly pinched the upside-down jar in the sink with his right hand, which was almost full of gas and flipped it directly next to the flame in his hand - the raging flames instantly illuminated the dull expressions of the students in the front row...... However, this raging flame came and went quickly, and dissipated into nothing before the students could fully react.

Then, in the astonishment of the crowd, André struck open the cauldron that had just been heated on the fire with his hammer, and used his iron tongs to remove the wood that had been completely carbonized by the oxygen......

Seeing that the charcoal, which had almost no flames, emitted a dark red glow, almost all of the students, including Kasanna, turned into a frowning expression and thinking about something.

"You have all seen the fire just now, and that is what we usually call the most common 'flame'. It's just that I've used some tricks to turn what is going to be a fire

The 'qi' was collected and completely ignited and burned in an instant. Isn't the moment these transparent 'qi' turn into 'fire' that everyone unexpectedly becomes extraordinarily intense?"

"So, although there is no visible flame in the charcoal in front of you, do you think it is burning now?"

"Your Highness, do you mean that our most common flames are actually 'solids' and 'liquids' that are transformed into 'qi' and then further into 'flames' in the process of being ignited!?

Andre had a smile of relief on his face - most of Valhalla's first cadets were from the best of the younger generation. In the face of such students, it is often enough to draw inferences and draw more conclusions in the process of learning new knowledge.

There are few unresponsive fools among these people, and their thinking and imagination are often limited by limited knowledge.
