In fact, many of the things that Ye Zan said, not to mention science and technology workers, even educated students in the technology world, will feel plausible and even full of loopholes. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 But so what? Ye Zan is not here to popularize science for these inner disciples, but just wants to introduce some of his ideas about spells through these introductions.

Moreover, many of the basics of the world of technology, the theorems and laws that almost every middle school student knows, may not be fully applied in this world. For example, the sun is not a star, but a condensation and manifestation of the so-called "Great Dao". The moon is not a small moon that does not emit light, but is the condensation and manifestation of another avenue that is not inferior to the sun. In addition, this realm is not a planet, nor does it rotate or rotate, and the rotation of day and night and the changes of the four seasons are also another form of display of the "Great Dao".

Another example is the fire that Ye Zan is now mentioning, saying that fire is a phenomenon that emits light and heat in the combustion of matter. But can this explanation really explain everything? You must know that in this world, in addition to this common fire, there are also different fires such as the Red Lotus Karma Fire, the Otomu Green Fire, the Netherworld Cangyan, and the Nanming Lihuo. This is also one of the reasons why people in this world generally regard fire as a material existence, and do not think about the "phenomenon".

Of course, there may be many things in this world that seem mysterious and mysterious, but in the end they can be explained by science. However, this process of interpretation, or verification, takes a lot more circles than the original verification method. Perhaps, those different fires with different names and different power functions are just phenomena produced by the combustion of a specific substance, but how can Ye Zan verify it?

Anyway, the current Ye Zan has the cultivation of the Yuanying Realm, and he has a very high rank in the Yuqing Sect, and no one dares to question what he says. 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 have to think about how to convince these disciples. It can be said that whatever he says is what he says, as long as it is not something particularly shocking, none of these disciples dares to question it.

Ye Zan proposed temperature, and linked temperature to power, although not particularly absolute, but in some ways it can still be said to be in the past. Fire spells, which mainly deal damage to the enemy, at least in the more elementary spells, are burning damage. As for explosions, there aren't really many of the primary fire spells that can deal explosion damage, or only have limited explosion damage.

Let's just say that this rudimentary 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 restrain a ball of flame into a ball. Therefore, when this fireball hits the enemy, due to the disappearance of the binding force, there will also be a small explosion-like effect, but the damage of the explosion is extremely limited. In fact, such an explosion is just the diffusion of energy from the flames that are unbound.

Of course, the explosion itself is a process or phenomenon in which energy instantly breaks through the shackles and is converted into other mechanical energy to spread around. Firecrackers, for example, only when tightly wrapped in paper will explode if the gunpowder can produce enough energy. And if there is no package, it is simply spread on the ground with the gunpowder, and after lighting it, you can hear the sound of "clusters".

Therefore, there is an important condition for the explosion, that is, there must be a small enough space and enough binding force to restrain the energy, so that the energy can quickly accumulate to a certain extent. Just like a grenade in the tech world, if it is wrapped in a paper shell, it is a large firecracker. However, using metal as the outer shell can allow enough energy to accumulate inside. Of course, using metal as a shell also has an important effect, that is, it can form fragments after the explosion, causing fragment damage to the enemy.

And the binding force of the fireball technique is obviously not able to reach the level of a metal shell. Moreover, even if it was really made into a metal shell, the flames generated by the spell would not be enough to break through the solid metal shell. That would really be a smash on someone, or you might be able to burn your opponent a little, but don't expect it to explode.

Another important condition, and arguably indispensable, for an explosion is that the volume expands violently in an instant. Why do firecrackers explode? It is because the gunpowder burns, which instantly produces a large amount of gas, and the gas will produce great pressure under the confinement of the shell. The Fireball Technique, on the other hand, is just a simple flame, and it will not expand violently unless something else is added to it.

Of course, there are spells with explosion damage, and this world also has them. Moreover, the principle of this kind of spell is similar to that of the technological world, but the means of implementation are different. Basically, it is based on two mutually restraining spell energies, so that the two energies collide violently, and then produce an explosive effect. However, this kind of spell is often considered relatively advanced, after all, it is necessary to manipulate two spell energies at the same time, at least the people who build the foundation realm can't do it.

Of course, Ye Zan has also studied those spells that have explosive damage, and has tried to improve them. However, those things are not suitable for these foundation building disciples now, the road must be walked step by step, and the food must be eaten one bite at a time.

And now, what Ye Zan wants to teach these inner disciples is the means to raise the fire spell from the temperature. Explosions aside, the main damage of the Fire Spell is heat burning, and the higher the natural temperature, the greater the damage.

Ye Zan talked about the elements of combustion, and the ignition point temperature of combustibles did not say much, mainly talking about the impact of combustibles and combustibles on combustion, in other words, the impact on fire.

These disciples all knew that the fire would be extinguished when it was suffocated, but no one really explored why. They also knew that the wind would make the fire stronger, but they also didn't explore why. For them, these things are taken for granted, so why should they ask why?

It's just a different way of thinking and a different focus, not that people in this world are stupid. You know, in the world of science and technology, before the development of science, people didn't know these things, can it be said that those ancients were stupider than later people. If there were no discoverers, perhaps the vast majority of modern people would not be much better than the ancients. If no one proposes heliocentrism, no gravitational force, no one proposes the existence of air pressure, and so on, there will probably be no difference between people thousands of years from now and people thousands of years ago.

In front of those disciples, Ye Zan did a small experiment, but he didn't say anything about oxygen, only that there was an existence in the air, which was an indispensable thing in combustion. This statement did not arouse the resistance of those disciples, after all, they also knew that the "wind" had the effect of enhancing the fire. However, immediately afterwards, another experiment done by Ye Zan, an experiment to prove the effect of oxygen combustion, 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 it is possible for me to ignite this iron bar without using spells, just using ordinary fire?"

If Ye Zan used spells, those disciples below would definitely answer "yes" without hesitation. Although in fact, even if the Primal Ancestor performed the Fireball Technique, the temperature of the fireball would not be much higher. However, the Yuanying Realm is already an incomparably powerful existence for the disciples, so in their hearts, there is nothing that the Yuanying Ancestor can't do.

However, Ye Zan said that it was without using spells, just using ordinary fire. In other words, in the matter of igniting iron bars, the cultivation of the Yuanying realm would hardly play any role, which made those disciples hesitate a little.

"Or, if any of you were to do it, would there be a way to set this iron bar on fire?" Ye Zan added another condition, also because he was afraid that his own cultivation would make those disciples have the idea of blind faith.

Hearing Ye Zan's additional conditions, those disciples finally stopped hesitating, and said babblingly: "Impossible, how can you light it like that, unless it is put in the furnace." ”

Seeing that the disciples were so cooperative, Ye Zan finally nodded with satisfaction, and said with a smile: "Then, next, it's time to witness the miracle, pay attention to it." ”

With Ye Zan's words, the lecture hall instantly fell silent. Although the disciples were still full of disbelief, no one dared to talk about anything at this time, and looked at Ye Zan's hands with bated breath.

Ye Zan tied a small wooden stick to one end of the iron bar, stretched out to the fireball that had been floating next to it and ignited the small wooden stick, then took the iron bar to the glass bottle containing oxygen, and slowly poked the iron bar through the mouth of the bottle.

Those disciples looked at Ye Zan's movements with curiosity on their faces, and saw that it was only a small wooden stick used to ignite the fire, and they looked forward to the miracle that Ye Zan said in their hearts. In their opinion, if Ye Zan had directly lit the iron bar with a fireball, it might have been possible to set the iron bar on fire. But on the small wooden stick, the bean-sized flame, they wanted to light the iron bar, but it really made them have no confidence.

However, as the iron bar poked into the glass bottle, the small wooden stick that had been ignited suddenly and violently burned, and the flames the size of the bean emitted an inappropriate light, and instantly burned to the iron bar tied to the wooden stick. Then, just when everyone thought the fire would be extinguished, the iron bar suddenly emitted a blinding light, and splattered out a little spark, which looked like it was clearly ignited.

"Ahh This experiment in the world of science and technology, which was done by junior high school students, was instantly stunned by a group of adults in this world. I'm afraid that any junior high school student in the technology world will say with disdain when he sees this scene: Phew, a bunch of dirt buns who have never seen the world!

The flames on the iron bar burned fiercely, but not for long. After all, the oxygen in the glass bottle is limited enough to keep the iron bar burning until it runs out. When the flames were extinguished, Ye Zan took out the iron bar and said to the people, "Do you see that?"

Although, the burning end of the iron bar only melted into an inconspicuous droplet. However, these disciples all have the cultivation of the foundation building realm, and they can still clearly see the changes on the iron bar with good eyesight. Originally, they still wondered if Ye Zan had done something wrong, or if the iron bar was just glowing. However, seeing the droplet-shaped iron beads after melting and condensing, who can no longer doubt whether the iron bar was ignited just now.

"It's really lit!"

"Yes, the little flame that was drawn with that little stick actually lit all the iron!"

"It's incredible!"

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

"Why is it that such a small flame can ignite this iron bar? As I have just told you, the ignition point of this iron is not low, so it can be said that with the help of this combustible, the temperature of the flame reaches the ignition point of iron. Now, you know how important this combustible substance is to the combustion that has always been present in the air around us. Ye Zan made a summary of this little experiment.

In fact, according to the physical knowledge of the scientific and technological world, iron does not have a so-called ignition point. Therefore, Ye Zan is right to do this experiment, but if people in the technology world hear this summary, I am afraid they will not be able to help laughing again.

Of course, Ye Zan also knew about this problem, and the reason why he said this was just to let these disciples understand the importance of combustibles. After all, these disciples are all cultivators, and you said that they said that this fuel aid is so important and so important, it is better to let them see the effect of this fuel on the spell, which can be regarded as a temptation.

"I see, that combustible thing actually has such a powerful power, I didn't know until today!" said a disciple as if he had suddenly realized.

"I always thought that using the wind to help the fire was just to make the fire spread faster, but I didn't expect that there was this reason in it. "There are also disciples who think of more.

Ye Zan put away the iron bars, cleaned up the things that were doing the experiment, and waited until the disciples were talking quietly, and then he said: "You have all seen the importance of combustibles with your own eyes, so what is the help of this for the fire spell?"

Hearing this, those disciples immediately stopped talking, and everyone looked at Ye Zan intently, waiting for Ye Zan to give an answer. They also knew now that what this Ancestor had come to tell himself and others was probably about the improvement of spells.

It's too important to them. After all, with their cultivation, if they want to cast any powerful spells, it is simply impossible. And the power of primary spells is really limited. So, if there's a way to increase the power of the spell without increasing the true dollar spend, it's tantamount to giving them another killer feature.
