Lin En suddenly spoke up at this time. "In fact, your three laws of fire are very good, and there is no big problem."
Adela paused, surprised and confused, and almost thought she had heard it wrong.
But before he could ask, Lin En continued to explain. "But I need to correct a few points. For example, oxygen is indeed a sufficient condition for the combustion reaction, but it is not a necessary condition!"
"To be precise, all we need is an oxidant!"
Hearing this, everyone present frowned.
Sufficient condition and necessary condition - these two new words seemed a little unfamiliar to the few people, but they could still understand them. However, they did not understand the oxidant.
An oxidant is a substance that gains electrons in a redox reaction. For example, chlorine trifluoride is a very strong oxidant and fluorinating agent, which directly replaces the role of oxygen. This is one of the reasons why it can burn as long as it comes into contact with matter (fuel) in a vacuum!
However, there are not many elements that can act as oxidants, and most of them are compounds...
Given the limited knowledge of Raphael and others, Lynn did not give a long explanation, otherwise he would have to first explain what redox reactions are, and then start talking about the internal structure of atoms...
So after considering for a moment, Lin En spoke as briefly as possible. "In layman's terms, certain elements can replace oxygen as a condition for igniting flames, so they can continue to burn even in an oxygen-free environment..."
Chapter 338: The Insidious Cardinal Edelweir
"I know, just like the sun... the sun can also burn in a vacuum!" Lydia said quickly. Lin En had mentioned this strange phenomenon when he was teaching them astronomy, but he did not explain the reason.
Lin En shook his head in amusement. The light of the sun is not produced by combustion, but comes from nuclear fusion inside the sun. The light and heat are just appearances.
However, the example given by Lydia was very easy to understand, and Adela understood it immediately. It was not that combustion did not require oxygen, but that other elements could be used as a substitute.
"So that's it."
In fact, he had done similar experiments before, but the dozen elements used in the experiment could not replace the role of oxygen, which led to the conclusion that oxygen is essential for combustion.
But why can stones and metals also be used as fuel?
Lynn did not intend to continue explaining. After extinguishing the "Eternal Flame" in his palm, he turned to look at Anthony and said with a smile.
"Master Anthony, I didn't expect you to be so quick. You've perfected the laser magic in just a few hours."
He remembered that he had just handed the relevant drawings to Anthony in the morning, which could be said to be the same time as the development of the two kinds of magic!
"It's just a prototype and it's far from perfect." Anthony said with emotion.
This kind of laser magic, which Lin En called the elemental excited state, has a total of five energy levels. For the time being, he can only produce lasers of the third energy level.
In addition, there is a second way to enhance the power of laser, which is to compress the diameter. The smaller the diameter of the laser, the stronger its destructive power!
After he compressed the laser from five millimeters to 0.5 millimeters, its power increased several times, and its destructive power was roughly equivalent to the level of five-ring magic. It could be further compressed with almost no end.
In Anthony's opinion, this is magic with no upper limit. As long as it is compressed to a small enough level, it will definitely reach the level of legendary magic!
"I just wonder which legendary figure came up with this theory of excited states of elements?" Anthony asked curiously. The person who proposed this theory had a profound understanding of the elements.
"This is something I developed based on Glenn's focusing magic and combined with the elemental structure theory within the [Society of Mysticism]," Lynn explained casually.
When measuring the elements before, he said in person that the research on light by the [Mystical Society] was also in its early stages. It would be bad to slap himself in the face now, so Lin En could only reluctantly take the credit on himself.
Raphael and others didn't know what to say. During the period after the seminar, this magic star not only created the terrifying fire magic, but also had the leisure to study and modify laser magic.
The gap between people is even bigger than that between people and dogs...
"Speaking of which, who won this battle?" Sanchez asked suddenly out of the blue.
For the practical Sanchez, discussing these magical theories is far less important than arguing about winning or losing.
The situation on the field was extremely dangerous just now, and the outcome was about to be decided, but unfortunately it was stopped by Raphael.
Sanchez's words undoubtedly attracted everyone's attention. Lynn's fire magic was terrifying, but Anthony's laser magic was also impossible to dodge when it swept across.
"Of course I lost!" Anthony responded calmly.
He couldn't stop the 'Eternal Flame', but Lin En might be able to stop his laser magic. After all, the principle of this magic was what Lin En told him, and there must be a way to counter it.
Anthony was very open-minded. Facing a former legend, it was normal to lose.
The only thing he didn't expect was that he would lose so quickly...
Anthony admitted it so readily that Raphael and others were somewhat surprised. Then they all looked at Lynn. A four-ring wizard defeating a six-ring wizard was an almost overwhelming victory. If they told others about it, not many people would be willing to believe it.
"Since there is no result, let's just consider it a draw." Lynn had no intention of taking advantage of Anthony. He didn't care about winning or losing. He was already satisfied that he could have a fight and figure out that the properties of chlorine trifluoride were the same as he thought.
It is difficult to determine the winner of a battle between wizards until the very last moment, after all, no one knows what strange magic the other side can come up with.
The outcome of the battle was just glossed over, which made Sanchez, who was originally very interested, feel bored, so he had to change the topic to the next war.
Due to the obstruction of the Griffin Knights, the reconnaissance function of the airship has been greatly reduced in the past few days. The pilots only dare to observe with binoculars from a distance of at least three kilometers.
Even so, he was almost shot down.
The insidious Edwyre was really good at scheming. He actually hid some of the griffin knights in the woods, let the army move slowly, and then suddenly rushed out of the woods when the airship approached for reconnaissance.
If the pilots hadn’t reacted immediately, and the two airships hadn’t been running fast, they would have been destroyed…
Because of this, very few pilots are willing to conduct close reconnaissance, so now we can only barely know the movements of this legion and cannot obtain more intelligence.
Although laser magic has been developed now, it will take a long time to put it into service on a large scale. Lin En suggested that this magic could be taught to some trustworthy formal wizards, who could be used as humanoid laser launchers.
Seizing air superiority is crucial, as it can greatly reduce casualties...
"It would be better for us to do it ourselves and get rid of these annoying griffins until they dare not take off!" Adela said viciously.
"No, this won't be effective!" Lynn shook his head.
Although these great wizards can fly, they are far less agile in the air than the Griffin Knights. Even if they launch a surprise attack, they can only kill dozens of griffins at most and cannot stop other Griffin Knights at all.
You have to know that the number of cardinals in the Holy See is likely to be greater than theirs. This group of people has not shown any intention of taking action so far, and they may launch an attack at any time. If they waste their magic power and leak information about key magic, it will be difficult to be countered in subsequent battles.
Either don't take action, or once you take action, you must destroy the entire Griffin Knights!
Otherwise, if these people successfully retreated and thought about it for a while, they might be able to come up with a way to crack the laser magic, and then they would face endless harassment.
Magic and divine arts have the same origin, so this is not impossible...
Chapter 339: This person is the destroyer of Harbor Town, the mastermind behind the destruction of the church!
On a hot summer day, in the Kingdom of Hadrata, in the wilderness several kilometers away from the capital.
A large black shadow was spreading from the other side of the horizon towards the royal capital. Brown flags were flying in the air, accompanied by the sound of drums and horse hooves. Everything was in great order.
"They're coming so fast!" Raphael and others stood on the city wall, staring at the army that was approaching from a distance. It was a dark mass with no end in sight.
A rough estimate is that there are at least 80,000 people... They are roughly divided into three groups. The legions on both sides are large in number, but the formation is a bit scattered, and even the soldiers' weapons and armor are incomplete.
"Hebrew, Austin, Barrow... these traitors of the kingdom!" Hattar said gritting his teeth, but he recognized from the towering flags and the ancestral emblems on the flags that these were the troops of several border dukes of the kingdom.
Lin En cast the magic of farsightedness and looked at the silver-armored army guarding the center. All members were tall and strong, marching forward solemnly, with pairs of cold and ruthless eyes staring forward, which was intimidating.
This is the renowned Divine Punishment Army. In just ten days, the Vatican's army had already reached the outskirts of the royal capital.
In fact, according to the intelligence they obtained, there were some desperate nobles who tried to resist along the way, but it was all in vain. The solid city walls could stop the ground troops, but could not stop the griffin knights who fell from the sky.
The entire city would fall within an hour without even the bishops taking action.
"Do you need us to go out of the city to fight, Lord Linn?" Redel asked with a serious expression.
Old York and others on the side had expressions of anticipation and eagerness to try.
Although the Vatican's army was much larger than theirs, they were not afraid. Back then, Duke Rickman led an army several times larger than theirs, but he was still beaten to a pulp by their muskets...
So in Old York's view, these were not 80,000 enemy troops, but human heads that needed to be fought for.
"No, it's not the right time yet!" Lynn shook his head.
According to the current production speed of laser launchers, it will take about two or three days to install them on the airship. If we rashly go out of the city to fight without gaining air superiority, there may be considerable casualties.
After all, their opponents this time are not just feudal soldiers with swords, but also possess powerful divine powers.
"What do you think, Your Majesty Hattar?" Lin En turned his head and looked at the king beside him.
Hattar was extremely anxious. Now that large tracts of territory in the eastern part of the kingdom had all fallen, he wished he could immediately command these wizards to rush out to defeat these damned Vatican legions, recover the lost territory, and execute those rebellious nobles.
But Hattar finally held back. He knew that Lin En's words meant that he was not completely sure, so he gritted his teeth and said, "Then let's do it this way. Defend... instead of attack!"
……
At the same time, the Vatican's army stopped in the wilderness outside the royal capital.
A middle-aged man wearing silver armor and with a holy emblem painted on his chest kept his eyes focused on the city wall. With his outstanding eyesight, he could still clearly see his target among the crowd from several kilometers away. He spoke with interest.
"Is that the great wizard Lin En who is wanted for 300,000 imperial gold coins? He is much younger than I thought..."
"Don't be careless, Arno. This is not an easy target to deal with." Edwill, wearing an iron mask, spoke solemnly, and then told the other party the information about Lin En.
This great wizard was previously wanted for 50,000 imperial gold coins for the crime of burning down the harbor town, and he had written the wanted number himself. Now that he had planned this rebellion in the kingdom, the bounty had naturally been increased, and now it had accumulated to a whopping 300,000!
This is an extremely exaggerated amount of money. Even a poor man with this money can buy a powerful duke position!
In the sinner chapter of the Bible, the description of the other party also includes the destruction of the kingdom church, the killing of the cardinal, and... the crime of blasphemy!
He can only be described as an unforgivable criminal; among all the wanted criminals that have appeared in the pages of the Bible before, no one can be compared to him!
"He controls a strange kind of hellfire that can devour human flesh and blood. It is difficult to extinguish it using normal methods." Edwill reminded.
"But as long as we isolate the elements in the air, we can stop it from burning. In addition, non-combustible sand and rocks can also bury it. Temperature is also a key factor..."
Edwill described it in great detail. He had previously sent people to find the wreckage of the airship and analyzed the characteristics of the flame. The bishops tried various methods and finally buried it with sand.
"In that case, I'll accept the three hundred thousand bounty!" A smile appeared on Arno's lips, and he kept Edelweir's words firmly in his heart.
"If you have this ability, his ice magic is not weak either..." There was no expression on Edelweir's face with the iron mask. After reminding him again, he turned to look at the dukes of the kingdom.
"Hebrew, Austin, Barrow... you will lead the kingdom's army as the vanguard!"
"But... Lord Edwell, those wizards can cast all kinds of strange witchcraft. I'm afraid we can't even get close to the city wall alone." Duke Barrow said with a slight tremor.
The kingdom's nobles who were watching on the scene also looked as if they wanted to say something but were hesitant to do so. Although they chose to surrender without hesitation when the Vatican's army came, it did not mean that they were very pious.
According to the intelligence we have obtained, the army trained by these wizards will use a strange witchcraft weapon that is extremely powerful.
An entire unit of well-trained cavalry was easily defeated during the charge. Even if they could capture the capital, they would probably suffer heavy casualties.
"This is your only chance to prove your loyalty to the Lord and repent of your sins!" Edelweir's words were full of irrefutable meaning.
