Collect crowd into immortals

Chapter 178 Research on the Comprehension Version of Incendiary Bombs
"Special fertilizer? Lightning spell?"

"Well, it is to use lightning spells directly in the air. The stronger the lightning intensity and the higher the density, the better the effect!"

"So simple?"

"Anyway, that's what my mother said! By the way, it seems that that part of the air must be introduced into the water, otherwise it will be useless!"

"All right!"

In Fengdeng Valley, Chen Qingxuan nodded thoughtfully when he heard the research of his aunt and the others.

The lightning technique breaks through the air, dissolves in water, and then acts as fertilizer. This...

It seems a bit like lightning nitrogen fixation!

But in the end is not, try to know!
After thinking about it, Chen Qingxuan didn't delay, and stretched out his big hand directly, forming a transparent spherical protective shield (spiritual light shield) more than one foot in front of him, and wrapped part of the air in it.

Then he directly activated the [Lightning Art] spell rune map in the sea of ​​consciousness.

The moment the rune map was activated, silver snakes began to dance wildly in the transparent ball, and the electric light flickered and crackled. It was so lively.

Seeing this, Chen Qingxuan narrowed his eyes slightly, looking expectant.

He wants to see if things are not as he imagined.

If so, that would be amazing.

You know, this world has extraordinary energy like aura.

Aura, and lightning nitrogen fixation?

This...well, there seems to be no contradiction in this.At least, Chen Qingxuan couldn't tell.

And just as the thunder and lightning flashed, Qing Yu on the side also turned his gaze.She wanted to see what new tricks her second brother could come up with this time.

Before, when she heard from her mother, she had tried it herself, and the special fertilizer could indeed provide certain substances to the plants, but other than that, she hadn't found anything else.However, she felt that her second elder brother had always been smart and wise, so she might have made some unexpected discoveries.

Unexpectedly, just as he was thinking, an unspeakable feeling suddenly came from his nose.

It's itchy, sour, and very uncomfortable.

Qingyu looked up suspiciously, only to realize that for some reason, the previous circular protective cover was gone, gone.

No wonder it smells so bad.Also so familiar.

As soon as this thought flashed through her mind, Qing Yu caught a glimpse of her second brother's wicked smile, and she immediately understood that it was her second brother's fault.

"You want to poison me to death!"

After reacting, Qing Yu quickly turned her head, covered her nose, and then attracted a gust of fresh wind to disperse the smell just now.After that, there is time to continue complaining.

"Smelly second brother, bad second brother, can't you learn something better? You think about bullying your sister all day long! Hmph! I'll ignore you!"

Seeing her turn her head and leave, Qingxuan quickly pulled her back.

"Hey, hey, don't run, don't run! It's the second brother who is wrong, and the second brother wants to apologize to you! But the second brother also wants to verify the truth of the matter and see if the smell is really bad. It's really not. Other purposes.”

"Then why don't you lie down on it and smell it yourself, and make me suffer too!"

"Well... Aren't we brothers and sisters? Between brothers and sisters, shouldn't we have the same blessings and share the hardships? Second brother, this is also an expression of love for our family, Qingyu."

"You should go and love my sister Youning! I can't stand your sister!"

Qingyu rolled his eyes.

How can you love your sister so much?Day by day, they either make me smell some unpleasant things or hit me on the head. Are you here to suffer as your sister?The thing about enjoying happiness is that you didn’t even think about me at all!

Of course, at this moment, Qingyu completely ignored the fact that the second brother took her to find delicious and fun things, and took her to fly around pretending to be aggressive.

In her words, these are what a brother should do. As for those bad things, they must not be done by a brother.

She keeps the good ones, and must reject the bad ones!
Thinking like this, and seeing that her second brother had already apologized, Qing Yu also stopped leaving.

She can't leave before she sees the new tricks!

But at this time, she saw that her second brother Qingxuan looked thoughtful at first, and then summoned a large spherical shield of about ten feet.

"So big? Isn't it necessary?"

Qingyu was just about to complain when he saw his second brother gently hold it with his right hand, and then he saw the sphere shield shrinking rapidly. In just a few breaths, it shrank to the size of one foot.

"What is this for?"

Qingyu was confused.

Well why shrink it so small.She calculated silently, and this was directly reduced to one thousandth of the original size.

However, the second elder brother Qingxuan didn't explain much about it, he just said: "Look carefully!"

Afterwards, Qing Yu saw the electric light start to flash again inside the protective cover.

But she didn't know if it was an illusion, she always felt that each flash of lightning this time lasted longer than before.

But this is not important, because very soon, Qing Yu saw an astonishing scene.

After each flash of lightning, a strange filament will be left in place. The filament is brownish red, like a branch of a tree, with many branches but closely connected.

"These are... are left by Lei Dian?"

Qingyu frowned and whispered softly.

She noticed that these filaments that appeared were almost exactly the same as the lightning trail that had just flashed past.

From this she came to the above inference.

"But it shouldn't be! It just didn't exist!"

Yes, obviously not!

You must know that she had paid close attention before, and there was nothing visible left behind after the thunder and lightning.Why did the second brother become like this when he arrived?
Qing Yu tilted her head, puzzled.

But at this moment, she suddenly thought of her second brother's operation just now, and a flash of lightning flashed in her mind, "Is it because of the compressed air?"

As soon as the questioning was over, before the second brother could answer, Qing Yu nodded seriously, "That's right, it should be this! It must be this! Otherwise, it doesn't make sense!"

After all, she doesn't think that her second brother really has any special magic skills, so the most likely explanation is that the second brother used some special operations, which led to this result.

And at this time, Qingyu's second brother's words of affirmation also came from Qingyu's ear.

"That's right! This should be the reason! When I just tried it, I looked at the sun once, and felt that the color of the air around the thunder and lightning seemed a little strange, so I wanted to try compressing it, but I didn't expect to give it a try. Out."

Hearing this, Qing Yu nodded slowly.

My second brother is a phenomenon that can only be seen after being compressed a thousand times. Before the compression, it is only natural that she didn't notice it.

"But why is this reddish-brown?"

Looking at the dense brown-red filaments inside the protective shield as the silver snakes danced around (some of them had become thicker or lighter), Qingyu still found it difficult to understand.

Isn’t the air colorless and odorless? Why does it change like this after lightning?
Not only has it become pungent, but it has also become colored.

"I don't know about this!"

Qing Xuan shook his head.

Ask him this, how does he know?
Well, no, he shouldn't know!
Can he say that this is because oxygen and nitrogen reacted chemically in a lightning environment to generate nitric oxide, nitrogen dioxide, and ozone?

This is obviously not something he should know.

Otherwise, Liumei will ask herself later what is oxygen?What is Nitrogen?What is a chemical reaction?What can he say, can he say that he is reincarnated?
This can't be!

So, he can only pretend not to know!

It's just that he was also puzzled, isn't this the world of cultivating immortals, how can there be substances such as nitrogen dioxide produced.

Or are these phenomena just a coincidence?
After thinking for a long time, he couldn't think of a reason, so Chen Qingxuan could only suppress it.

Anyway, he will definitely pursue longevity and strength.Those physical chemistry and the like in the previous life can only be studied carefully when I am bored in the future.

But just when he thought of this, another idea suddenly appeared in his mind.

Maybe, give these to them?

Just sit back and enjoy the results and pay attention to the results regularly.

After a while, when the brown-red gas no longer increased or became thicker, Chen Qingxuan directly drew a stream of water from the nearby stream with his right hand, and forced it into the protective cover in front of him.

"Huh, it's actually getting lighter?"

Qingyu exclaimed.

Because she suddenly discovered that with the injection of water, the color inside the protective cover actually began to gradually become lighter and lighter.

And when the water in the protective cover reached half of the volume inside the cover, and Chen Qingxuan shook it violently a few times, the color of the gas in the protective cover almost disappeared.

The reason why I say almost is because shortly after the brownish red disappeared, the color inside the protective shield suddenly deepened until it finally turned into light yellow.

Afterwards, even if Qingyu asked the second brother to add water several times, the yellow color could not disappear and would always pop out.

Seeing this, the two could only give up this plan.

"Why can't it be eliminated?"

"I don't know! Maybe it can't be dissolved in!"

"Then why can the others dissolve?"

"Well! This depends on my aunt!" Chen Qingxuan glanced at the big sun in the sky and blinked.

"Okay! Forget it, forget it, let's see the effect of fertilization first."

As she said that, Qingyu ran away excitedly, and after a while, she ran over holding a few corn seedlings.

"Try this first!"

"Wait a minute, let me relieve myself."

With that said, Chen Qingxuan slowly loosened his grip on the protective shield.

The next moment, I saw that the protective cover was expanding rapidly like a balloon, and in the blink of an eye, it expanded to seven or eight feet, hundreds of times larger.

But seeing this, Qing Yu was puzzled and said: "Why is it not as big as before?"

"You forgot, there is still a lot of melting here!"

Speaking, Chen Qingxuan pointed to the water channel at the bottom of the protective cover.

"Oh, yes! They all dissolved into the water."

Qing Yu suddenly realized. "Second brother, quickly open the top, let's see the effect quickly."

Before, her mother did not compress the air when she showed it to her, nor did she have the brownish-red gas, nor did it have such a high concentration, so Qingyu really wanted to try it out, is there anything strange about this high-concentration special fertilizer? Effect.

Just do it.

With just a swipe of Chen Qingxuan's finger, the upper part of the protective shield completely disappeared without a trace.Then, he controlled the bottom to shrink and deform.

In the end, a small square pond less than a foot long was formed.

Seeing this, Qingyu didn't hesitate and directly put three fresh corn seedlings in.

But before she could carry out the next spiritual rain ripening work, the roots of the corn seedlings that had just been put in turned black with a few pricks.

"Uh!"

There is no way, Qingyu can only stop the plan just now.

Because through her spiritual consciousness, she suddenly discovered that the blackened corn seedling had completely died.It's hopeless!

"Dead? What the hell is this?"

Isn't it a fertilizer that can speed up plant growth? How did it become like this?
If she hadn't seen its effect before, Qingyu would have thought someone was joking with her.

Is this fertilizer?

Are you sure this is not a poison that destroys life?
And just when she was wondering, she saw that her second brother Qingxuan directly found an ant on the ground and put it in.

The result was only an instant, and before the ant had time to struggle, it also ended up in the same fate as the corn seedlings, turning into black charcoal.

Seeing this, Qing Yu had no choice but to give up the idea of ​​trying it herself.

If this goes on all of a sudden, maybe her white and tender fingers will turn into ugly charcoal immediately.

Although for an immortal cultivator, this injury is nothing at all and can be cured in a few strokes, but Qingyu doesn't want to suffer that kind of punishment.

How painful it must be for a good finger to turn into charcoal!

Afterwards, the two tested the concentrated solution several times, and found that no matter if it was a twig or a small fish or shrimp, it could be directly turned into charcoal immediately after entering it.Lost life.

In fact, even the hard stone will bubble continuously and become riddled with holes when placed inside.

Seeing this, Qing Yu sighed again and again: "This is almost comparable to many poisons that can eliminate flesh and dissolve bones."

"It's really amazing!"

Qing Xuan nodded.

Isn't it? This is one of the three most famous strong acids in the world in the last century. It is also one of the "three acids and two bases" that is the basis of the chemical industry. How awesome is it!

Even if it is changed to a fantasy world, this alone can support a series of corrosion spells.

That's right, Chen Qingxuan has now confirmed that the one in front of him is nitric acid, and it's still concentrated nitric acid.

After dilution, plants can absorb it, and it can be generated by dissolving a brown-red gas in water. The brown-red gas can be generated by lightning and air. Isn't this the famous nitric acid?

As for why there is still nitric acid in the world of cultivating immortals, only God knows.

"I'll try it too!"

After the brother and sister diluted the nitric acid and found that it could indeed be absorbed by plants, Qingyu quickly shouted that he wanted to try it himself.

After a while, she saw her smiling like her second brother, compressing the air a thousand times, and then began to fix nitrogen with lightning.

When she saw the beautiful lightning-like red filaments inside the ball she formed, Qingyu was even more happy and couldn't find the north.

She was greedy just now, and now she finally has it.

However, as the number of brown-red filaments increased, Qing Yu suddenly frowned.

"Huh, that's not right, why does it feel like the pressure is getting less and less?"

It turned out that because the air was compressed more than 1000 times, she had been using a lot of mana to maintain the pressure and prevent it from expanding back. But as the lightning proceeded and the number of thin red lines increased, Qingyu But I felt that the mana required to maintain a one-foot-sized shield was greatly reduced.

It's almost reduced by more than [-]%.

And when the red thread no longer produced and the lightning technique didn't work, Qing Yu found that the pressure had been reduced by [-]%.

But at this time, as the lightning technique didn't work, this trend of reducing pressure also disappeared impressively.

After she injected water into the protective cover and absorbed the brown-red gas, the pressure dropped rapidly again, and it was more than [-]% less.

This……

After that, she can still understand that it is soluble in water, and the pressure should be reduced.But the previous one, why did it suddenly decrease?

Is it because of the generation of that brown-red gas?
So what is that brown-red gas?

Why can it be produced by lightning and air?
Why can it be absorbed by plants?
In response, Chen Qingxuan spread his hands and shook his head. "It depends on the eldest aunt and nine aunts."

"Okay! Then I'll go find my third sister and the others! Second brother, keep busy!"

After finishing speaking, the little girl ran out bouncingly, cheering as she walked: "Third sister, third sister, let me show you something good, I guarantee you haven't seen it before."

And not long after, Qingzhu's surprised voice came.

"Is this fertilizer? Don't show me poison!"

"This is really a fertilizer! My mother and the others tried it by themselves, and it is indeed effective. But my second brother and I improved it and increased its concentration, and then it became like this!"

"Fertilizer? It can be absorbed by plants, but it can directly kill the plants and turn them into black charcoal. This is really amazing! How on earth is it done? Let me try it too!"

"Okay! It's actually very simple, first like this, then like that, and then..."

……

Listening, Chen Qingxuan chuckled, and then came to the stream again, ingested a five-inch water polo, and then wrapped it with an airtight protective cover.

The next moment, he actually released [Thunder and Lightning Technique] directly in the water polo.

Crackling, lightning flashing.

Compared to air, the sound of electric shocks in water is a bit duller.And it seems that water is easier to conduct electricity. Compared with air, the arc in water is longer and travels faster.Often just a flash of lightning can dazzle the entire transparent and easy-to-light.

But these are not the focus of Chen Qingxuan's attention. What he wants to see is whether this [Thunder and Lightning Technique] can achieve the effect he wants.So he observed very carefully.Always pay attention to all the movements in the water.

At this time, another lightning flashed across the water polo, causing ripples.But on the trajectory of the lightning, Chen Qingxuan noticed the change he wanted to see with his divine sense.

"There are indeed bubbles!"

Yes, he observed that with each flash of lightning, a large number of tiny bubbles burst out of the water.

It's like boiling water.

It's so dense, it's overwhelming!
With the generation of bubbles, the air pressure inside the water balloon also increased slightly.Seeing this, Chen Qingxuan also released the suppression of the outer shield, allowing it to expand and increase freely.

And it was exactly as he expected, sure enough, with the continuous operation of the lightning technique, the space above the water polo also expanded more and more.

In just a few breaths, it expanded to the same volume as the water polo below.

But at this moment, Chen Qingxuan found that part of his vision was blocked, and the inner wall of the transparent protective cover was covered with water droplets.

this is……

Could it be water vapor?

Wait, could it be that what I just collected is water vapor!
Chen Qingxuan was stunned for a moment, and then immediately stopped the [Thunder and Lightning Technique].Then in order to verify his guess, he used [Freezing Technique] to form a small ice cube in the center of the water polo to lower the temperature inside the protective cover.

And sure enough, as the ice cubes melted, the temperature inside the protective cover dropped greatly, correspondingly, the air layer inside the protective cover also decreased rapidly.

After half a stick of incense, only a small gas space the size of a thumb was left.

So, these are what I want?
So much, what can this do!

Chen Qingxuan couldn't help complaining in his heart.

Before, he had endless daydreams about this hydrogen bomb, but he didn't expect that most of the gas produced after electrolysis was actually water vapor.

Where is this going to make sense?
Moreover, are these remaining gases really the hydrogen and oxygen produced by electrolysis?Rather than incompletely condensed water vapor?
Chen Qingxuan expressed doubts.

In order to verify this point, he immediately boldly faced it with a [Lightning Art].

Of course, he also subconsciously released an aura shield for himself in advance to ensure his own safety.

【Lightning Technique】The moment it is activated...

A banging sound rang out from the water ball, a strong light flashed, and the air pressure increased sharply, shaking the water inside and sending ripples everywhere. The outer protective shield also expanded sharply, and then quickly shrunk.

Seeing this, Chen Qingxuan was overjoyed.

It seems that it is still effective.

In this case, if I increase the number of them, will I be able to create a special bomb, no, it should be called Thunderbolt!

"Try it and you'll know!"

After all, Chen Qingxuan started to act again, but this time he directly added a small ice cube to the container, so that it could cool the container all the time and eliminate the interference of water vapor as much as possible.

Soon, the experiment begins here.

With the operation of the lightning technique, the bubbles in the water polo kept gushing out, making the container bigger and rounder.And on the inner wall of the container, the liquid also flows down like sweat.Correspondingly, the area of ​​ice cubes above the water polo also keeps decreasing.

Everything went as smoothly as Chen Qingxuan expected.

But just when the ice inside was about to disappear, and Chen Qingxuan was about to replenish it with [Freezing Technique], suddenly, a sharp hissing sound sounded for no reason, and the container containing the liquid was blown to pieces.

The water in the container seemed to feel the violent explosion, and was blown into water mist on the spot.Permeated over the creek.

"What happened?"

Hearing the explosive sound resounding through the valley, Qingzhu, Qingyu and the others also ran out of the room without caring about anything else.

As a result, they saw that their second brother walked out of the mist with a confused expression on his face.

"Second brother, what are you doing?"

Several people quickly stepped forward, and after confirming that their second brother was fine, they questioned him.

They were shocked just now, they thought someone had attacked Lianhu Island.In the end, who would have thought that it was actually the masterpiece of my second brother.

"Uh, I didn't do anything. I just wanted to try the lightning technique in water. Who would have thought that such a thing would happen."

Chen Qingxuan looked innocent.

He still doesn't know what happened.

Although, he was indeed producing hydrogen and oxygen just now, preparing to develop it into a thunderbolt in the cultivation world, but who would have thought that it was being electrolyzed, and why it suddenly exploded.

There is so much water in the middle, and there is also a layer of ice cubes, it stands to reason that there is no way to touch the top.

What's more, in order to prevent accidental explosions, he concentrated all the lightning and lightning at the bottom of the water, so they couldn't touch the top, but why did it explode?
It doesn't make sense!

"It's really just that?"

Qing Yu was a little unbelievable.

She still knows the virtues of her second brother.The other party looked innocent at this time, probably causing trouble.

How could there be an explosion if you just use the lightning technique to electrify the water? This is unreasonable!
They had tried it before, but this didn't happen.

Regarding this, Chen Qingxuan had nothing to say, so he could only ask a few people to try it.

In the afternoon of that day, deafening roars sounded from time to time in Fengdeng Valley.

"How did this explode?"

"It's obviously water, so why can it explode? And the power is not small, it's comparable to ordinary small spells."

Naturally, Chen Qingxuan couldn't explain it.

But he actually had a problem that he didn't understand, and that was why oxygen and hydrogen exploded when they were mixed together without being ignited.
Doesn't it mean that it will explode when it encounters an open flame or reaches the ignition point?

I have ice cubes to keep the temperature down all the time, and I can't reach that temperature at all!

After that, Chen Qingxuan tried many times, but they all exploded halfway, for no reason, and could not wait for the moment when he gathered a large amount of hydrogen and oxygen.

Sometimes he even collected some mixture of hydrogen and oxygen when the amount was small, and then wanted to compress it, but it suddenly exploded when he pressed it.

(When there are ice cubes on the periphery to cool down)

In this regard, he shook his head helplessly, and could only temporarily give up this plan.

Before, he had thought that after gathering enough oxygen and hydrogen, he could send the enemies spiraling into the sky, but now it seems that he can only put it on hold temporarily.

……

In the evening of that day, when Qingyu returned home and demonstrated everything she had learned today, her mother Xu Wenhui was completely stunned.

"How could this be possible?"

"You can actually see red gas when you compress it?"

"After being dissolved in water, it can corrode plants and animals and kill the vitality in them. It can even corrode holes in stones. Is this really the kind of fertilizer I showed you?"

"The gap between the two is too big!"

In response to her mother's question, Qingyu nodded affirmatively, "It's true! My second brother, third sister, and I also diluted it, and it was indeed absorbed by the plants. Also, we also did not compress it. I tried it in the air, and as long as the lightning intensity is high enough, you can still see a little color. At this time, as long as you compress it, the color will become darker and redder."

"So, are they really the same?"

Xu Wenhui nodded thoughtfully.Since it can all be done in reverse, then [-]% of it is the same thing.

And after she personally tested it once, she confirmed it even more.

But when Qing Yu raised her question, even Xu Wenhui, who was the first to discover this phenomenon, shook her head again and again, "These mothers don't know. After the mother finds out, she must tell our family Qingyu as soon as possible. OK?"

"All right!"

"By the way, you still talk about me, how is your spell consummation?"

"There is a little eyebrow!"

……
