There is a creature in the world that needs to complete the transition from larva to adult growth in the "hell", and leave the "hell" in time to crawl out of the ground, one of the representatives is the 17-year-old cicada.

This cicada is no more, no less, and it will take 17 years of "hell" to see the light of day, and it will take another 17 years to see its children.

Like astronomers waiting for a solar eclipse and Halley's Comet, 17 year cicadas, their lifetimes are almost elusive.

These subjects, who were almost abandoned by God, could not choose their own fate at the beginning, and could only repeat their endless and miserable lives in the orbit of the "cicada" over and over again.

Li Luant saw the cicada whose cry was gradually declining, and the words that Wogua had just said at this time came out of his mind again.

"Hey, you say, could it be that you're looking for an immortal technique?"

"Time is money, and if you can find a way to get a lot of time in the end, isn't that the most precious thing in the world? Once there is more time than others, let alone an enterprise, it is a country, and in time, it will be above all countries! ”

"Is it possible that they want to find a medicine that can rejuvenate and rejuvenate, but this medicine, only a certain ancient person has researched it, but before they have time to eat it, they brought the secret to their own grave, but it was known by future generations, so they went to find it, after all, who can bring the current memory and rejuvenate again, then the ending will be different."

The Long March-2 701403 (Y3) was successfully launched.

Wait, wait.

Li Luant's pupils shrank: Wogua's words are not all unreasonable.

Rejuvenation, longevity, and ...... years These speculations are all related to one thing, that is, time!!

"Quick, you tell me again, when you saw the pendant in Xu Weihang's hand."

Jin Yuan Bao saw that Li Green Ant was suddenly solemn, probably thinking of something, and began to carefully say it again like a few family treasures, Li Green Ant listened to it in his ears, and began to compare with the scene he saw in Fan Li's Golden Treasure as if he was in the Golden Collection, and found an amazing fact.

If the gold ingots and themselves are not crazy and what they see is true, then there are two histories now, and one of these two histories seems to have been reluctantly repaired by someone, but the people living in this world have not found that history has changed in the slightest, which shows -

Li Luant raised his head, his throat was slightly astringent: Those who revised history back then failed.

Wogua is very scared, never take the waterway again, so the two of them turned to the passenger car, ready to return to Yangzhou from Nanjing, who knows that just arrived in Nanjing, Wogua must be here for a few days before leaving, left and right, now it is still in the summer vacation, Li Green Ant had to agree.

It was summer, the sun was hot, the two went to the Sun Yat-sen Mausoleum in high spirits, when taking the bus through Hongjing Avenue in Jiangning District, Li Green Ant probe saw that there was a "Nanjing XXXX College" outside the car window on the school emblem, smiled slightly, Wogua also thought that Li Green Ant saw a beautiful woman, whistled and poked his head out, who knew that the ground was full of uncles and aunts, wondering, "Your aesthetics are a little interesting." ”

Li Luant shook his head, "I'm not looking at people, I'm looking at that." Pointing to the English sign under the Chinese logo of its school, "You see, it says it is 'XX INSTITUTE OF TECHNOLOGY', which surprised me." ”

Institute generally refers to research institutes, institutes, followed by a university, the professionalism is stronger, because UNIVERS originally represented the meaning of "turn", and was also extended by scientists to "universe" and other extremely vast things, these two words are connected together, when it means a school, it means that the school must be able to include any discipline in the world, that is, all-encompassing, and it must be extremely top-notch, in order to be called "universe". There is only one school like this in the world.

Massachusetts Institute of Technology, Massachusetts Institute of Technology.

Massachusetts generally refers to the state of Massachusetts, which is a state in the United States, officially known as the "Commonwealth of Massachusetts", located in the northeastern part of the United States and part of the New England region.

In foreign countries, a highly professional university is called a college, and a comprehensive university is called a university! No university in China is qualified to use these two words together, only Massachusetts in the world can, and Massachusetts itself is very low-key, and it is not used together. Can you slip the world so ridiculous??

It is very difficult to admit that others are excellent, but only by admitting it can you become excellent, and if Dong Shi is not good enough on this basis, it is really a little intriguing.

Wogua blinked his eyes, "You don't allow people to be, don't you allow people to say?" The mouth grows on someone else, another day I will open a school, not anything else, just call it the University of the Universe, what can you do with me? ”

Nowadays, universities are keen to change their names, often change their names often cost hundreds of thousands, a series of assembly lines down, more troublesome than going to the battlefield, the joints are not ordinary people can imagine, such as so-and-so university, in order to highlight their own spirit, simply do not name after the characteristics of the school, only the place with the word "school", the ancients often said "with my surname, crown your name; In this life and this life, I will never leave it; Sympathize with each other", what is sung is beautiful love, and here, it has become a tool for comparing with each other.

Originally, it was a quiet and quiet small school, but it had to be a good job, from a certain technical school, simply changed to East China University, slowly, how can this place in East China afford its temperament? Simply changed to Northeastern University, good guy, directly encompassing more than half of China's land.

As the saying goes, "greed is not enough for a snake to swallow an elephant", slowly, the word "XX University" is a bit difficult to fill, and it is simply changed to a Chinese university, but the name is still too small in his eyes, so it is simply changed to a world university, and what will be the Earth University, the Galaxy University, and the Universe University in the future...... This is all a reasonable thing, I hope that scientists will step up, hoping that on the basis of the University of the Universe, a few more places will be discovered, which are larger than the universe, so that he can have more room for progress, otherwise millions of tuition fees are in his pocket, and he will not spend on changing his name, which will always be a bit of a trembling and itchy on his stomach.

Li Luant waved his hand, "Because Jinling Institute of Science and Technology was a vocational school at the beginning, there is no need to mind." Change the name, change the name, as long as it's still on Earth, it doesn't matter what it is. ”

As soon as I came out of the subway entrance, I felt a steaming heat rushing to my face. The road leading to the inner garden is a wide and clean avenue, and the road is planted with tall and dense French plane trees, which are the tree species transplanted in Jinling by the power of the whole country in the past, separating the head from a scorching heat, and lining the streets of every Republic of China relic in Stone Town.

Wogua muttered while wiping his sweat, always keeping an eye on the navigation. It was even more difficult to walk forward, the road became a slope, and the shared bicycles, which had disappeared at the entrance, were now lying casually on the edge of the grass on the uphill road. Thinking it was coming, there were still hundreds of steps to cross before the real high-rise building, so it's no wonder that most of the tourists gather under the daunting steps to enjoy the cool breeze.

If you finally reach the top, under the peak of the Zhongshan Mausoleum, this stone town is also a city surrounded by green mountains. The cloudy clouds in the distance are in harmony with the tip of the green mountain, tight and blending, and the middle of the mountain is in the clouds, and the green hazy is not very good. And the inscription "Mr. Sun of the Chinese Kuomintang Funeral Premier is here" that he had previously admired also complemented this scene and stood straight.

Looking at the boundless beauty in front of him, Li Luant was very unfortunate at this time, thinking of what happened four days ago when he came here.

The night before Obon –

The gold ingots turned a powerful flashlight in front of him, making it flash and flash, as if to guide the direction, Li Green Ant followed this oversized sea fish to swim over, it should be night, the radiation range of the flashlight is limited, everything should be very blurry, but unexpectedly, there are a large number of glowing fish and plankton on the bottom of the sea passing by, more mysterious beauty than during the day.

The figure of the nest melon seems to be a crab that has eaten up, showing its teeth and claws in front, and now Li Luant doesn't know what he wants to see what he wants to see, but he goes into the water and swims a short distance, and the nest melon finally stops in front.

Li Luant thought that the nest melon was deliberately stopped, so he stepped forward to probe, but who knew that the face of the nest melon under the diving goggle was very ugly, and his lips couldn't stop moving, as if he was trembling.

"Wogua? Nest melon?! Li Luant shook his shoulder, because the bottom of the sea could not speak, and the voice could not be communicated, so only Li Luant himself could hear his heart, and he could only make lip talk, but Wogua had been with him for so long, he must be able to understand, but Wogua was trembling all over, as if he was afraid of something, his eyes kept looking around, Li Luant originally thought that Wogua was afraid of something, but at this moment, a strange feeling of coldness climbed on his bare skin.

What is it!

Li Green Ant was frightened, and quickly turned around, protecting the nest melon behind him, but he didn't know if the nest melon was scared stupid, and he didn't move, Li Green Ant just shook him for a long time without panting, when Li Green Ant turned around, he found a large number of invertebrate, flashing starfish, octopuses and other soft creatures, as if fleeing for their lives, fart and urine rolled away from him.

In other words, these moving creatures fled with urine and urine, and those aquatic plants and other creatures seemed to be trembling and shaking their bodies, only hating the roots of the old trees, and they couldn't get out of the door and take away the door of their own house.

Wogua raised his hand with difficulty, grabbed Li Luant's arm, and muttered on his lips, "shell lang, run, run, leave me alone, run-run-"

Li Green Ant turned to look behind Wogua at this time, but saw that there was a fine and dense thorn like a thorn tree behind Wogua, trapping Wogua in place, making him unable to move, and the color of those things was nothing else, more like pure white after water condensed into ice, with a fluorescent flash, it seemed that in the process of freezing, the corpses of many plankton on the bottom of the sea were lit up.

It turned out that Wogua You couldn't move just now, and he was trapped by this thing, so he couldn't respond.

Li Luant just wanted to touch it, but within a few centimeters of approaching, an extremely cold frost enveloped his whole body: this thing was not actually a water weed, but a sudden condensation of water into ice, formed by an absolutely frozen freezing point?!!

Li Luant was shocked, and there are two prerequisites for confirming whether the water will freeze at 0 degrees: one is pure water, that is, pure water, distilled water without impurities. The second is that under a standard atmospheric pressure, both points are met, that is to say, the chill I just felt, and the running of the animals under the water are not my own illusions, it must be something that happened here, and this force first began to act on the body of the nest melon.

"Don't touch me, go quickly, hurry-" Wogua gestured weakly, and when he went into the water, Luan Jingjing taught some basic gestures, because he knew that his current physical condition was a sense of being frozen and crushed, and this thing was only a spider silk at first, wrapped around his legs, and he didn't pay attention to it, and then it began to grow like a virus, and when he turned around to remind Li Green Ant to leave, His back was completely controlled by this strange and cold icicle, and he couldn't move.

But strangely, when I felt these things coming, there was a sudden cold drop in the surrounding environment, and then this happened, wasn't this thing some kind of creature, but a joke played by the ocean on itself?

Li Luant forcibly touched these icicles with his hands, but found that those icicles seemed to be tumors, and they began to sweep towards him, and he looked at his palms in disbelief, as if they were frost in winter, and began to climb densely, and like a broken mirror, stretching in all directions: this thing is not what I think of as a submarine virus, this fucking is frozen!!

How can it be?! When I went into the water, I didn't notice it at all, and the temperature was also normal, not to mention that it was summer again, and the temperature was high even at night, and it was only a few dozen meters from the water surface here, and it was impossible for the temperature to drop to a few tens of degrees below zero!

Li Luant quickly rubbed off the frost on his hand, and took out the Luoyang shovel from his waist, which was stuffed by Qin Pianpian himself just before going into the water just now in order to prevent accidents, and now it seems that it is the right time, since this is not a virus, but freezing, but it is more contagious than a virus, and the person who touches it may be frozen as well as a nest melon, then he can use an insulator.

Like the electrocuted person, it is the most rational thing to separate the electrocuted person with an insulating object.

"Scandium, scandium—"

Although the sound can not be heard on the bottom of the sea, but those icicles are broken, if it is on the sea, the sound of colliding with the Luoyang shovel must be not small, Li Green Ant is fast-eyed, first release the hands of the Wogua, the Wogua hands are relieved, relieved, just ready to relax, who knows that those icicles that were knocked down and broken by the Li Green Ant are actually like earthworms that can regrow after a broken head, with a more tenacious and tragic speed, the whole body of the Wogua is quickly wrapped, Li Green Ant was shocked, and grabbed the hand of the Wogua, But he felt a strange cold, which instantly enveloped the two of them together, making him think of something.

Water freezing, of course, is related to the two important factors that must be discussed before, but when a special situation is reached, the temperature rise will also freeze: first, the high temperature causes high-speed evaporation; The second is the decrease in viscosity caused by high temperature. When the water is splashed out, the water is covered with a thin layer of water on the ground, and the speed of freezing is not related to the total mass of the water, but to the quality of the water per unit area, that is, the thickness of the water layer directly affects the freezing state.

"Whoa—"

It seemed to be the sound of the object being vaporized, and the body of the Li Green Ant was quickly wrapped in the fine linen freezing point, and the golden ingot's eyes flashed with strong unwillingness, at this moment, with the help of the only hand that could still move, he threw the Li Green Ant who grabbed him out, and the Li Green Ant stumbled and hit the aquatic grass not far away, and the nest melon seemed to be buried alive, and it was no longer visible.

Countless fluorescent substances are also encapsulated inside, and water is very pure and can be seen to the end, but ice is different.

"Wogua!!"

Li Luant's eyes were red, and he was about to run over with the Luoyang shovel: It doesn't matter what kind of bird virus he is, or what kind of special water reaction of high temperature, Lao Tzu's brothers shouldn't be buried alive in the ice ballast!

But at this moment, a super-large jellyfish was followed by countless glowing fluorescent squid, as if the whole clan was running away, and the Li green ant was rushed away, as if someone had put a high-pressure cannonball in the water, which exploded at the bottom of the water, and the Li green ant was impacted and fell on the soft aquatic grass again, rolled a few times, and the big icicle wrapped in the nest melon disappeared.

Nest melon? Nest melon?

Li Green Ant searched everywhere without a master, but at this moment, after the surrounding underwater animals fled, they left a vacuum, and a strange scene occurred.

A wisp hung down from the surface of the water, as if it was an atomic model, and like an irregular extension of the molecular aggregation structure, slowly falling, like a white fluorescent veil, after falling in this water, suddenly like a malignant source of infection, quickly spread in a columnar shape, a hermit crab did not have time to escape because it happened to fall on a white spot that overflowed, and was frozen into a specimen in an instant, and never moved again, a pink starfish that was about to move, was floating in the water and escaped, but when the icicle sprayed out, It was also frozen into crystals.

At this moment, the surrounding temperature instantly dropped by dozens of degrees, Li Green Ant was originally wearing a diving suit, only felt cold, at this moment actually felt that the cold wind was biting, pervasive, so he shivered, and was about to leave, but saw that next to the death icicle that fell at the beginning, there was a human-shaped crystal, motionless, and the crystal seemed to be quite strong......

It's a nest melon!!

Li Luant's face changed greatly, but the temperature of the sea water in this area has dropped so fast, how can people still be allowed to shuttle freely here? Seeing that Wogua fell into that strange scene, surrounded by clusters, it seemed to be a battlefield, and bullets shot out everywhere.

I know what it is.

A trace of disbelief flashed in Li Luant's eyes: this strange scene is actually -

Only at this moment, Li Luant was heartbroken, although he knew that this thing in front of him would definitely kill people, but the nest melon was in front of him, and it was impossible for him not to save it!

Under what circumstances will the water freeze above zero?

Use phase change heat storage materials, such as inorganic salts to dissolve in their own crystal water: sodium sulfate decahydrate (Na2SO4.10H2O), sodium sulfate decahydrate is liquid above 32 degrees Celsius, and the following is solid, and a large amount of heat needs to be absorbed or released during the melting or solidification process (250kj/kg is 60 times the specific heat capacity of water 4.2kj/kg), and the anhydrous sodium sulfate can be added to the water in proportion (the amount of the substance (molar amount) ratio is 1:10).

Calcium chloride hexahydrate (CaCl2.6H2O), above 29 degrees Celsius is liquid, below is solid, and a large amount of heat needs to be absorbed or released during the melting or solidification process (180kj/kg is 43 times of the specific heat capacity of water 4.2kj/kg), and the proportion of anhydrous calcium chloride can be added to the water. The production of calcium chloride hexahydrate is actually to add excess anhydrous calcium chloride to the water, prepare a saturated solution, filter and remove the solid after the slight heat evaporation of water, and the precipitated crystal is calcium chloride hexahydrate.

There is also sodium dibasic phosphate dodecahydrate (Na2HPO4.12H2O) above 35.5 degrees is liquid, the following is solid, and a large amount of heat needs to be absorbed or released during the melting or solidification process (265kj/kg is 63 times of the specific heat capacity of water 4.2kj/kg), and the anhydrous disodium hydrogen phosphate can be added to the water in proportion.

Everything in the world, yin and yang, just like detectors and anti-detectors, when the water temperature drops to a certain extent, it can produce the situation seen in front of you, and when the water temperature meets certain special circumstances, it can also make the crystals freeze, then, as long as you use this and reverse the action, in a few very short moments, make your surroundings completely destroy the freezing conditions, you can avoid it!

And in order to achieve these few very short moments, and to destroy this situation, it is only necessary to take advantage of the three conditions that have been studied by mankind to freeze the temperature of the water for no reason, and in turn make other conditions untenable.

Sodium sulfate decahydrate, calcium chloride hexahydrate, disodium hydrogen phosphate dodecahydrate. Li Luant's face was silent: I don't have these three substances now, if I am on the boat now, I can still synthesize them, but now I am underwater!

I glanced at the oxygen cylinder I was carrying behind my back: the types of diving were divided into air diving, nitrogen and oxygen mixtures (artificial air diving), helium and oxygen mixtures (artificial air diving), hydrogen and oxygen mixtures (artificial air diving), and other gas mixtures.

The gas breathed during scuba diving activities is filled in the "diving cylinder", and the filled gas is not high-pressure oxygen, but the air that is breathed daily, the air is a mixture of 78.01% nitrogen, 20.9% oxygen and argon, neon, xenon, krypton and other rare gases, and the gas filled in the diving cylinder is ordinary air that has been purified, compressed and dried, not liquid air that has undergone special treatment.

If you can make good use of it, you can only buy twenty seconds, and then use all your strength to take the gourd away, but if you don't grasp it, you will no longer have oxygen in the water, and you will be buried under the sea with the gourd!
