Chapter 536: Lure for Profit

In fact, many of what Ye Zan said, let alone scientific and technological workers, even educated students in the scientific and technological world would find it specious or even full of loopholes. But so what? Ye Zan didn't come here to popularize science for these inner disciples, he just wanted to draw out some of his ideas about spells through these introductions.

Moreover, a lot of basic knowledge in the world of science and technology, those theorems and laws that almost every middle school student knows, may not be fully applicable in this world. For example, the sun is not a star, but the so-called "Avenue" condensed and manifested. The moon is not a small, non-luminous satellite, but another avenue not inferior to the sun, which is condensed and manifested. Also, this realm is not a planet, nor does it have any rotation and revolution. The rotation of day and night and the change of seasons are also another form of display of the "Avenue".

For another example, Ye Zan mentioned fire now, saying that fire is the phenomenon of light and heat in the combustion of matter. But can this explanation really explain everything? You must know that in this world, besides the usual fire, there are other fires such as Honglian Yehuo, Yimu Qinghuo, Nether Cangyan, Nanminglihuo, etc. This is also one of the reasons why people in this world generally regard fire as a material existence, instead of thinking about "phenomenon".

Of course, many things in this world may seem mysterious, but in the end they can be explained by science. But this process of explanation, or the method of verification, is much more devious than the original verification method. Perhaps, those strange fires with different names and different powers and functions are just a phenomenon produced by the combustion of a specific substance, but how does Ye Zan verify it?

Anyway, the current Ye Zan has the cultivation base of Nascent Soul Realm, and has a very high seniority in Yuqingzong, no one dares to question what he said. In this world, the vast majority of people still have a deep sense of awe for authority, and authority comes from strength and seniority. Therefore, for Ye Zan, he can completely ignore those things, and don't need to think about how to convince these disciples. It can be said that what he says is what he says, as long as it is not particularly shocking, none of these disciples dare to question it.

Ye Zan proposed temperature, and linked temperature to power. Although it is not particularly absolute, it can still be said in some respects. Fire spells mainly cause damage to the enemy, at least in relatively elementary spells, it is burning damage. As for the explosion, among the basic fire magic, there are really not many that can cause explosion damage, or only have limited explosion damage.

Let's just say that the most basic fireball technique, although it looks like a ball, is actually incorporeal. It can be said that it is just using the rules of spells to constrain a group of flames into a spherical shape. Therefore, when the fireball hits the enemy, due to the disappearance of the binding force, there will be a small-scale explosion-like effect, but the damage of the explosion is extremely limited. In fact, this kind of explosion is just the energy diffusion of the flame losing its restraint.

Of course, the explosion itself is a process or phenomenon in which energy breaks through the shackles instantly and is transformed into other mechanical energy to spread around. For example, firecrackers, only when they are tightly wrapped in paper, will they explode when the gunpowder can generate enough energy. And if there is no package, just spread the gunpowder on the ground, and you can hear the sound of "cluster" after lighting it.

So there is an important condition for an explosion, that is, first of all, there must be a small enough space with enough binding force to restrain the energy, so that the energy can quickly accumulate to a certain level. Just like the grenade in the technological world, if it is wrapped in a paper shell, it is a large firecracker. But using metal as the shell can allow enough energy to be stored inside. Of course, using metal as the shell also has an important function, that is, it can form fragments after the explosion and cause fragment damage to the enemy.

The binding force of the fireball technique obviously cannot reach the level of the metal shell. Moreover, even if it is really made into a metal casing,

Even the flames generated by spells are not enough to break through the solid metal casing. That would really hit someone, and maybe burn the opponent a bit, but don't expect an explosion.

Another important condition for an explosion, and it can also be said to be an indispensable condition, is that the volume expands violently in an instant. Why do firecrackers explode? It is because the gunpowder burns and produces a large amount of gas instantly, and the gas will generate extremely high pressure under the constraints of the shell. And the fireball technique is just a pure flame, and there will be no violent volume expansion, unless something else is added to it.

Of course, there are also spells with explosive damage in this world. Moreover, the principle of this type of spell is similar to that of the technological world, but the means of realization are different. Basically, it is based on two kinds of magical energies that counter each other, let the two energies collide violently, and then produce an explosion effect. However, this kind of spell is often considered relatively advanced. After all, it needs to manipulate two spell energies at the same time, at least people in the foundational realm cannot do it.

For those spells with explosive damage, Ye Zan has of course also studied and tried to improve them. But those things are not suitable to be told to these foundation-establishing disciples now, the road has to be walked step by step, and the meal has to be eaten bite by bite.

But now, what Ye Zan wants to teach these inner disciples is the method of improving the fire magic from the temperature. Aside from the explosion, the main damage of the fire spell is high-temperature burns, and the higher the natural temperature, the greater the damage.

Ye Zan talked about the elements of combustion. He didn’t say much about the ignition temperature of combustibles. He mainly talked about the influence of combustibles and combustion-supporting substances on combustion, in other words, the impact on fire.

These disciples all know that the fire will go out if it is suffocated, but no one has really explored why. They also knew that blowing the wind would make the fire more intense, but again they hadn't explored why. For them, these things are taken for granted, so why ask why?

This is just a different way of thinking and a different focus. It does not mean that people in this world are so stupid. You know, in the world of science and technology, before the development of science, people also didn't know these things. Could it be said that those ancient people were stupider than those who came later. If there were no discoverers, the vast majority of modern people would not be much better than the ancients. If no one proposed the heliocentric theory, the universal gravitation, the existence of air pressure, etc., there might not be any difference between people thousands of years later and those thousands of years ago.

In front of those disciples, Ye Zan did a small experiment, but he didn't mention oxygen, he only said that there is a kind of existence in the air, which is an indispensable thing in combustion. This statement did not arouse the resistance of those disciples, after all, they also knew that "wind" had the effect of intensifying the fire. But then, Ye Zan did another experiment, which was used to prove the combustion-supporting effect of oxygen, which shocked all the disciples.

The experiment was very simple, that is, some pure oxygen was extracted first, and then Ye Zan took out a thin and thin iron bar, and asked everyone: "Do you think I just use ordinary magic without using spells?" Is it possible to ignite this iron bar?"

If Ye Zan used spells, the disciples below would definitely answer "yes" without hesitation. Although in fact, even the fireball technique performed by the Yuanying Patriarch, the temperature of the fireball will not be too high. However, the Nascent Soul Realm is already an extremely powerful existence for the disciples, so in their hearts, there is nothing that the Nascent Soul Patriarch cannot do.

However, Ye Zan said that he just used ordinary fire without using spells. That is to say, in the matter of lighting the iron bars, the cultivation base of the Nascent Soul Realm will hardly play any role, which makes those disciples hesitate a bit.

"Or, if any of you do it, is there a way to ignite this iron bar?" Ye Zan added another condition, because he was afraid that his cultivation would make those disciples have the idea of ​​blind faith.

After hearing Ye Zan's additional conditions, those disciples finally stopped hesitating, and said in a hurry: "Impossible, how can it be lit like that, unless it is put in the furnace."

Seeing the cooperation of his disciples, Ye Zan finally nodded in satisfaction, and said with a smile: "Then, next, it's time to witness the miracle. Watch carefully."

Following Ye Zan's words, the lecture hall fell silent instantly. Although the disciples were still full of disbelief, no one dared to whisper to each other at this time, and they all looked at Ye Zan's hands with breathless concentration.

Ye Zan tied a small wooden stick to one end of the iron bar, stretched it to the fireball floating beside him and ignited the small wooden stick, then took the iron bar to the glass bottle containing oxygen, and slowly put the iron bar Probe down from the mouth of the bottle.

Those disciples looked at Ye Zan's movements curiously, and seeing that the fire was only a small wooden stick, they looked forward to the miracle Ye Zan said in their hearts. In their view, if Ye Zan directly hit the iron bar with a fireball, it might still be possible to ignite the iron bar. But the little flame on the small wooden stick wanted to ignite the iron bars, which really made them feel unconfident.

However, as the iron bar penetrated into the glass bottle, the ignited small wooden stick suddenly burned violently, and the bean-sized flame emitted an inconsistent light, and burned to the iron bar tied to the wooden stick in an instant. Immediately afterwards, just when everyone thought the fire would be extinguished, the iron bar suddenly emitted a dazzling light, and sputtered out a little spark, which looked like it was obviously ignited.

"Ah!" Almost everyone, when they saw this scene, couldn't help but exclaimed. In the world of science and technology, this experiment was done by junior high school students, but in this world, a group of adults were instantly stunned. I am afraid that any junior high school student in the world of science and technology will see this scene and say with disdain: Bah, a bunch of bumpkins who have never seen the world!

The flame on the iron bar burned fiercely, but it didn't last long. After all, the oxygen in the glass bottle is limited, not enough for the iron bar to burn to the end. When the flames were extinguished, Ye Zan took out the iron bar and said to everyone, "Did you see it?"

Although, the burning end of the iron bar just melted into an inconspicuous droplet. However, these disciples all had cultivation in the Foundation Establishment Realm, and they were still able to clearly see the changes on the iron bar with their good eyesight. Originally, they wondered if Ye Zan had done something wrong, or if the iron bar was just shining. However, seeing the melted and condensed drop-shaped iron beads, no one can doubt whether the iron bars were ignited just now.

"It actually ignited!"

"That's right, the little flame sparked by that small wooden stick actually ignited the iron!"

"This is too incredible!"

Those disciples seemed to have forgotten the awe of Ye Zan for a while, and expressed their surprise in their hearts.

"Why can such a small flame ignite this iron bar? I just told you that the ignition point of this iron is not low, so this can show that with the help of this kind of combustion aid, the temperature of the flame has reached The ignition point of iron. Now, you know how important this combustion-supporting substance that has always existed in the air around us is for combustion." Ye Zan made a summary of this small experiment.

In fact, according to the physical knowledge of the scientific and technological world, iron does not have a so-called ignition point. Therefore, it is right for Ye Zan to do this experiment, but if people in the technological world hear this conclusion, they will probably not be able to help but laugh again.

Of course Ye Zan also knew about this problem. The reason why he said this was just to let these disciples understand the importance of fuel. After all, these disciples are all monks. If you say that the accumulator is so important, it is better to let them see the effect of the accelerant on the spell. This can be regarded as a lure.

"So that's how it is. The thing that supports the combustion actually has such a powerful power. I didn't know until today!" A disciple said as if he had suddenly realized.

"I always thought that the use of wind to help the fire was simply to make the fire spread faster. I didn't expect that there was a reason for it." Some disciples also thought of more.

Ye Zan put away the iron bars, cleaned up the things used for the experiment, and waited until the disciples' discussions became quieter, and then said: "You have all seen the importance of combustion aids, so this is very important for you. How can the fire spell help?"

Hearing this, the disciples immediately stopped talking, and all of them looked at Ye Zan attentively, waiting for Ye Zan to give an answer. They also know now that what the Nascent Soul Patriarch came to tell himself and others is probably about the improvement of spells.

This is too important to them. After all, with their cultivation base, it is impossible to cast any powerful spells. And the power of elementary spells is really limited. So, if there is any way to increase the power of spells without increasing the expenditure of true energy, it would be like giving them another trump card.
