There is a creature in the world that needs to complete the transitional growth from larvae to adult in the "hell" at the right time, and leave the "hell" at the right time to crawl out of the ground. One of the representatives is the 17-year-old cicada.
This kind of cicada is neither more nor less. It spends exactly 17 years of "hell" life before seeing the light of day. It must take another 17 years to see its children.
Like astronomers waiting for solar eclipses and Halley's Comet, the 17-year cicada's life is almost elusive.
These subjects, who were almost abandoned by God, could not choose their own destiny from the beginning. They could only repeat their endless miserable life and miserable fate in the orbit of the "cicada".
Hell, there is no way to escape this reincarnation?
When Li Green Ant saw the cicada whose cry was gradually fading, the words that Wo Gua just said came to his mind again.
"Hey, tell me, are you looking for a way to live forever?"
"Time is money. If you can finally find a way to get a lot of time, wouldn't it be the most precious thing in the world? Once you have more time than others, let alone a company, it is a country. In time, it will be better than other countries.
!”
"Is it possible that they were looking for a medicine that could rejuvenate youth, but this medicine was only developed by a certain ancient person, but before he had time to take it, he took the secret to his own tomb, but it was known to future generations.
Therefore, if we look for someone who can bring the current memories and become a child again, the ending will be different."
The Long March 2 701403 (Y3) was successfully launched.
Wait, wait.
Li Lvyan's pupils shrank: What Wo Gua said is not completely unreasonable.
Rejuvenation, immortality, years... these speculations are all related to one thing, which is time!!
"Quick, tell me again what happened when you saw the pendant in Xu Weihang's hand."
Jin Yuanbao saw that Li Lvyi was suddenly solemn. He must have thought of something, and began to explain it in detail again. Li Lvyi listened to his ears, and began to feel like he was in a state of soul wandering. He saw in Fan Li's golden treasure.
Comparing the scenes, I discovered a surprising fact.
If Jin Yuanbao and himself 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 barely repaired by someone, but the people living in this world
But we didn’t find any changes in history, which shows that——
Li Lvyan raised his head, his throat a bit sore: Those who revised history failed.
Wo Gua was so frightened that he would never take the waterway again, so the two of them took a passenger bus and prepared to return to Yangzhou from Nanjing. Unexpectedly, when they arrived in Nanjing, Wo Gua had to stay here for a few days before leaving. Nothing happened to them.
, it was still summer vacation, so Li Lvyan had no choice but to agree.
It was summer, the sun was hot, and the two of them went to Sun Yat-sen Mausoleum with great interest. When taking the bus and passing Hongjing Avenue in Jiangning District, Li Lvyan looked out the window and saw the school emblem of "Nanjing XXXX College" on it, and smiled slightly.
When Wo Gua smiled, he thought Li Lvyan had seen the beauty, and whistled as he poked his head out. Unexpectedly, the floor was filled with old men and women, and he wondered, "Your aesthetics are quite interesting."
Li Lvyan shook his head, "I'm not looking at people, I'm looking at that." He pointed at the English logo under the Chinese logo of the school, "Look, it said it was 'XX?IEOLOGY'. This tone was so loud that I felt
Accident."
Institute generally refers to a research institute, followed by a Uy, which makes it more professional, because UNIVERS originally meant "turn", and was later extended by scientists to include "universe" and everything including extremely vast
When these two words are connected together to mean a school, it means that the school must be able to cover any subject in the world, that is, it must be all-encompassing, and it must be extremely top-notch in order to be called a "school."
"Universe", there is only one school like this in the world.
Massachusetts ?Ieology,Massachusetts Institute of Technology.
Massachusetts generally refers to Massachusetts. Massachusetts is a state in the United States, officially known as the "Commonwealth of Massachusetts". It is located in the northeastern United States and is part of the New England region.
Abroad, a highly professional institution is called a college, while 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.
They have not joined forces to work together. How can this Jinling Institute of Science and Technology be so virtuous? Can it deceive the world into such a big joke?
It is very difficult to admit that others are excellent, but only by admitting it can you become excellent. And if you imitate others, but you are not good enough on this basis, then it is really thought-provoking.
Wo Gua blinked his eyes, "If you don't allow others to be who they are, why don't you also allow others to say it? Your mouth is open to others. One day, I, the commander-in-chief, will open a school. It will be called Universe University if you don't call it anything else. What can you do to me?"
Sample?"
Nowadays, universities are keen on changing their names. Changing a name often costs hundreds of thousands. It is more troublesome than going to the battlefield to go through a series of assembly lines. The joints involved are beyond the imagination of ordinary people. For example, a certain university, in order to highlight
His own spirit was simply not named after the characteristics of the school, but only the word "school" after the place. The ancients often said, "With my surname, I will give you your name; I will never leave you in this life; I will support each other and cherish each other."
What is beautiful is love. Here, it has become a tool for comparison.
Originally a quiet little school, if it had to neglect its business, it would simply change from a certain technical school to East China University. Slowly, how could this place in East China be able to set off its temperament? Just change it to Northeastern University, good guy.
, directly covering more than half of China's land.
As the saying goes, "The greedy snake swallows the elephant." Gradually, the four words "XX University" became a bit overwhelming, so he simply changed it to China University. However, the name was still too small in his eyes, so he simply changed it to World University.
, in the future there will be an Earth University, a Galaxy University, a University of the Universe... These are all reasonable things. I only hope that scientists will step up their pace and hope that on the basis of the University of the Universe, they will discover a few more places that are more beautiful than the universe.
Only in this way can he have more room for improvement. Otherwise, if he keeps millions of tuition fees in his pocket and does not spend them on changing his name, he will always feel a bit wary and itchy on his buttocks.
Li Lvyan waved his hand, "Because Jinling Institute of Science and Technology was originally a vocational school, so
There’s no need to worry about it. Just change your name. As long as you’re still on earth, it doesn’t matter what you change it to.”
As soon as you get out of the subway, you will feel the steaming heat hitting your face. The road leading to the inner garden is a spacious and clean avenue. Tall and dense French plane trees are planted along the road. They were transplanted in Jinling in the past with the efforts of the whole country.
That tree species isolates the scorching heat above our heads and grows in every street that is a relic of the Republic of China in Stone City.
Wo Gua muttered while wiping his sweat, always watching the navigation. It was more difficult to walk forward, the road turned into a slope, and the shared bicycle that had disappeared at the entrance was now lying casually beside the grass on the uphill road. He thought it was coming. , who knew that there were still hundreds or even thousands of steps for me to cross before I reached the real tall building. No wonder most tourists gathered under the daunting steps to enjoy the cool air.
If we finally reach the top, the stone city under the summit of Sun Yat-sen Mausoleum is also a city wrapped in green mountains. The mist-shrouded clouds in the distance meet the top of the green mountains, tightly and blending together. Half of the mountain is completely hidden in the clouds, and the green mist is not very good. The inscription "The Kuomintang of China buried Prime Minister Sun here" that I paid homage to earlier also stands upright in harmony with this scene.
Looking at the boundless beautiful scenery in front of him, Li Lvyan was very unlucky at this moment, thinking about what happened four days ago when he came here.
The night before Bon Festival——
Jin Yuanbao adjusted the powerful flashlight in front, making it flash continuously, as if to guide the direction. Li Lvyan followed the oversized sea fish and swam over. It was supposed to be night now, and the flashlight's radiation range was limited. Everything was in danger. It should be very blurry, but unexpectedly, there are a large number of luminous fish and plankton passing by on the seabed, which is more mysterious and beautiful than during the day.
The figure of Wo Gua looked like a full-fed crab, flexing its teeth and claws in front of him. Now Li Green Ant didn't know what he wanted to see, but he got into the water and followed him for a short distance, and Wo Gua finally stopped in front.
Li Lvyan thought that Wo Gua had stopped on purpose, so he stepped forward to explore. Unexpectedly, Wo Gua's face under the diving goggles was very ugly, and his lips kept moving, as if he was trembling.
"Wogua? Wogua?!" Li Lvyan shook his shoulders, because the bottom of the sea cannot speak, and the sound cannot be conveyed, so only Li Lvyan can hear his own voice, and he can only speak with his lips. But after Wo Gua has been with him for so long, he must understand, but Wo Gua's whole body was trembling, as if he was afraid of something, and he kept looking around. Li Lvyi originally thought that Wo Gua was afraid of something, but instead At this moment, a strange cold feeling crawled onto the exposed skin.
What something!
Li Lvyan was shocked, and quickly turned around to protect Wogua behind him, but he didn't know if Wogua was frightened and couldn't move. Li Lvyan just shook him for a long time without taking a breath, thinking that Li Lvyan When he turned around, he found a large number of invertebrate, shining starfish, octopuses and other soft-bodied creatures, rolling away from him like they were running for their lives.
Just like that, these moving creatures fled like shit, and the water plants and other creatures seemed to be trembling and swaying, just because the old trees were entangled with roots and could not escape from the door and take away the door of their home.
Wogua raised his hand with difficulty, grabbed Li Lvyan's arm, and murmured "Dung beetle, run, run, leave me alone, run - run -"
At this time, Li Lvyan turned around and took a look behind Wo Gua, only to see a thin, dense thorn tree-like thorn behind Wo Gua, trapping Wo Gua in place, making him unable to move, and those things were The color is nothing else, more like the pure white color of water after it condenses into ice, with a fluorescent flash. It seems that during the freezing process, the corpses of many plankton on the seabed were involved and lit up.
It turns out that Wo Guayou was unable to move just now. He was trapped by this thing, so he couldn't respond.
Li Lvyan just wanted to touch him, but within a few centimeters of approaching, a kind of extremely cold frost enveloped his whole body: this thing is not a water plant, but water that suddenly condenses into ice, with an absolutely freezing effect.
Freezing point formed?!!
Li Lvyan was shocked. To confirm whether water will freeze at 0 degrees, there are two prerequisites: one is pure water, that is, pure water, distilled water without impurities. The other is that under a standard atmospheric pressure, both points must be
That is to say, the chill I felt just now and the underwater animals running for their lives were not my illusions. They must have happened here, and this force first began to act on Wogua.
on the body.
"Don't touch me, go quickly, go quickly -" Wo Gua gestured feebly. When entering the water, Luan Jingjing taught some basic hand gestures, because he knew that his current physical condition was such that his internal organs would be frozen.
The feeling of being on the verge of despair was shattered. At first, this thing was just like a spider thread, wrapped around his leg, and he didn't notice it. Then it started to grow like a virus. When he turned around, he wanted to remind Li Lu
When the ant was about to leave, his entire back was completely controlled by this strange and cold icicle, making him unable to move.
But it's strange. When I felt these situations coming, the surrounding environment had a sharp drop in coldness, and then this happened. Isn't this thing some kind of creature, but a joke played by the ocean on itself?
?
Li Lvyan forced his hands to touch these icicles, only to find that the icicles seemed to be cancerous tumors and began to sweep towards him. He looked at his palms in disbelief. They seemed to be like frost in winter and began to be densely packed.
Clinging, it's like a broken mirror, stretching in all directions: This thing is not the submarine virus I thought, this damn thing is frozen!!
How is that possible?! I didn't notice anything when I entered the water, and the temperature was normal. What's more, it's hot summer now, and the temperature is high even at night. It's only a few dozen meters away from the water. No matter how low the temperature is, it won't suddenly drop below zero.
Dozens of degrees!
Li Lvyan quickly rubbed off the frost on his hands and took out the Luoyang shovel from his waist. Qin Pianpian stuffed it on himself just before going into the water to prevent any accidents. Now it seems that it is the right time. Since this is not a virus, but
It is ice, but it is more contagious than the virus. If someone who touches it accidentally may be frozen as solid as a melon, then use an insulator.
Just like the person who gets an electric shock, it is the wisest thing to separate the person who gets an electric shock with an insulating object.
"Scandium--"
Although there was no sound at the bottom of the sea, the sound of those icicles shattering and colliding with the Luoyang shovel would have been loud on the sea surface. Li Lvyan had quick eyesight and quick hands. He first released Wo Gua's hands, and Wo Gua's hands were freed.
He breathed a sigh of relief and was about to relax. Unexpectedly, those icicles that were knocked down and broken by Li Green Ants turned out to be like earthworms that can grow again after their heads are cut off.
Like an earthworm, it quickly wrapped around Wo Gua's whole body at a more tenacious and cruel speed. Li Lvyi was shocked and grabbed Wo Gua's hand, but felt a strange coldness, instantly killing the two people.
Shrouded together, it reminded him of something.
Although water freezes, it is related to two important factors that must be discussed before. However, when it reaches certain special circumstances, the temperature rise will actually freeze: first, high temperature causes high-speed evaporation; second, high temperature causes viscosity to decrease.
.When the water is poured out, it will cover the ground with a thin layer of water. At this time, the speed of freezing has nothing to do with the total mass of the water, but is related to the mass of water per unit area, that is to say, it is related to the mass of the water layer.
The thickness directly affects the icing state.
"呲呲——"
It was like the sound of an object being vaporized, and Li Lvyan's body was quickly wrapped in fine lines of ice. Jin Yuanbao's eyes flashed with strong unwillingness. At this moment, with the help of the only hand that could still move, he fiercely
He swung the Li Green Ant who had caught him hard. Li Green Ant stumbled and hit the water plants not far away. The nest melon seemed to be buried alive and could no longer be seen.
Countless fluorescent substances are also sealed inside. Water is very pure and can be seen to the bottom, but ice is different.
"Wogua!!"
Li Lvyan's eyes turned red, and he was about to rush over with the Luoyang shovel: No matter what kind of bird virus it is, or some special high-temperature water reaction, none of my brothers should be buried alive in the ice!
But at this moment, an oversized jellyfish was followed by countless glowing fluorescent squids, seeming to be running away as a whole family, rushing away the Li green ants, as if someone had put a high-pressure cannon in the water, and it was under the water.
After exploding, the Li green ants were hit and landed on the soft water plants again, rolling several times, but the big icicle wrapping the nest melon disappeared.
Wogua? Wogua?
Li Green Ant was searching everywhere without a master, but at this moment, the seabed animals in the surrounding area fled, leaving a vacuum area, and a strange scene happened.
A strand hangs from the water, which looks like an atomic model or an irregular extension of a molecular aggregation structure. It falls slowly, like a white fluorescent gauze. When it lands on this piece of water, it suddenly looks like a malignant infection.
Like a source, it quickly spread in a columnar shape. Before it had time to escape, a hermit crab happened to land on a white spot that spread out. It was instantly solidified into a specimen and could no longer move. A pink starfish that was about to move,
He was floating in the water and escaping, but when the icicles shot out, he was frozen into crystals.
At this moment, the surrounding temperature instantly dropped by dozens of degrees. Li Lvyan was originally wearing a diving suit and only felt chilly. At this moment, he felt the biting and pervasive cold wind, so he shivered. He was about to leave, but saw that there
Next to the death icicle that first fell, there was a human-shaped crystal, motionless, and the crystal seemed quite strong...
It’s Wogua!!
Li Lvyan's face changed greatly. However, the temperature of the seawater in this area has dropped so fast. How can people still be allowed to freely shuttle here? Seeing Wo Gua fall into that strange scene and being surrounded, it seemed like a battlefield.
The bullets were shot out everywhere.
I know what it is.
A trace of disbelief flashed in Li Lvyan's eyes: This strange scene was actually——
At this moment, Li Lvyan felt his heart change. Although he knew that the thing in front of him would definitely kill people, the nest melon was right in front of him, so he couldn't help but save it!
Under what circumstances does water freeze when the temperature is above zero?
Use phase change thermal storage materials, such as inorganic salts dissolved in their own crystal water: sodium sulfate decahydrate (Na2SO4.10H2O). Sodium sulfate decahydrate is liquid above 32 degrees Celsius and solid below, and it needs to be melted or solidified during the process.
To absorb or release a large amount of heat (250kj/kg is 60 times the specific heat capacity of water 4.2kj/kg), just add anhydrous sodium sulfate to water in proportion (the amount (mole) ratio of the substance is 1:10).
Calcium chloride hexahydrate (CaCl2.6H2O) is liquid above 29 degrees Celsius and solid below 29 degrees Celsius, and needs to absorb or release a large amount of heat during the melting or solidification process (180kj/kg is 43 times the specific heat capacity of water 4.2kj/kg).
Just add the proportion of anhydrous calcium chloride to water. The actual preparation of calcium chloride hexahydrate is to add an excess of anhydrous calcium chloride to water to form a saturated solution, filter to remove the solid, then evaporate the water with slight heat, and the crystals precipitate
It's calcium chloride hexahydrate.
There is also disodium hydrogen phosphate dodecahydrate (Na2HPO4.12H2O) which is liquid above 35.5 degrees and solid below, and needs to absorb or release a large amount of heat during the melting or solidification process (265kj/kg is 63 of the specific heat capacity of water 4.2kj/kg
times), add anhydrous disodium hydrogen phosphate to water in proportion.
Everything in the world is yin and yang, just like a detector and an anti-detector. When the water temperature drops to a certain level, it can produce the situation you see before you. When the water temperature meets certain special conditions, it can also cause crystals to freeze. Then
, as long as you take advantage of this and reverse the effect, in a few very short moments, the environment around you will completely destroy the icing conditions, and you can avoid it!
To achieve these extremely short moments and destroy this situation, we can only use three conditions that have been studied by humans to cause the water temperature to freeze for no reason, and in turn make other conditions untenable.
Sodium sulfate decahydrate, calcium chloride hexahydrate, and disodium hydrogen phosphate dodecahydrate. Li Green Ant looked silent: He does not have these three substances now. If he were on the ship now, he could still synthesize them, but now he is
Under water!
I glanced at the oxygen bottle I was carrying on my back: Diving types are divided into air diving, nitrogen and oxygen mixed gas (artificial air diving), helium and oxygen mixed gas (artificial air diving), and hydrogen and oxygen mixed gas.
(artificial air diving), other mixed gases.
The gas you breathe when performing scuba diving activities is filled in the "diving cylinder". The filled gas is not high-pressure oxygen, but the air you breathe daily. Air is composed of 78.01% nitrogen. 20.
A mixture of 9% oxygen and rare gases such as argon, neon, xenon, and krypton. The gas filled in the diving cylinder is ordinary air that has been purified, compressed, and dried, not specially treated liquid air.
If you can make good use of it, you can only buy twenty seconds, and then use all your strength to take Wogua away. But if you are not sure, you will no longer have oxygen in the water, and you will die together with Wogua.
