Spike and Aurora have an indescribably subtle sensation that they have never experienced before, and their abilities are connected by water molecules, forming a kind of induction.

They looked at each other and thought of a deeper layer - since temperature can affect the surface tension of water molecules, wouldn't spikelets be able to further push the current limit with Aurora's assistance?

Chio didn't understand what the two of them were doing, why they suddenly stopped talking, and instead exchanged glances with each other that she couldn't understand.

"Try again. Aurora said.

"Good. ”

Spike reached for another bottle of water and poured out some.

When the water hits the ground, it is supposed to soak into the wet ground and then seep into the concrete floor, leaving only a wet stain.

As the saying goes, soldiers will block, water will cover the earth, and soil is the natural nemesis of water.

When Spike controlled the water before, she would try to avoid contact with dry soil or cement, which has strong hygroscopicity and a large number of fine holes, because once it is in contact, the water will be absorbed in large quantities, and she can only delay this process with all her might, but after all, she can't stop it, as soon as she touches the ground, her ability is useless, so when she attached the water balloon to the figure just now, she didn't dare to let the water ball completely wrap the figure, exposing the base and ankles, just to avoid the water ball touching the ground.

This time, Aurora also activated the ability at the same time.

So, this stream of clear water that flowed down ...... It turned into an ice spike and stabbed straight into the concrete floor, shattering its tip and falling back in two.

"Poofha!I know meow~ Olara is not enough to succeed and more than to lose, so let me help you......"

Jiang Chanji grabbed a handful of unsuitable hair on Mio's head, pulled her back, and didn't let her go over to make trouble for others.

"Sorry, I pushed too hard, let's do it again. ”

Aurora apologizes.

The faster she freezes the water vapor and carbon dioxide in the sky, the sooner she freezes the water vapor and carbon dioxide in the sky, the sooner she forms falling ice crystals, the sooner she can hit the enemy, because it takes time to fall, it is very important to grasp the timing, and if you miss the best time, you won't come back.

And now she has to cooperate with Xiao Sui, only make a small adjustment to the temperature of the water, and never let the water be cold to the point of freezing, which is also a very new thing for her, it is tantamount to using a cannon to fight mosquitoes, but is it a waste to use a cannon to fight mosquitoes? Not necessarily, if it makes sense to kill that mosquito, then even if it is a cannon.

"It's okay, haha, just a few more times. ”

Xiao Sui said with a smile, sure enough, it is very easy to cooperate with a student like Aurora, and there is no need to say anything, Aurora can understand it by herself, saving you half a day of talking but the other party still doesn't understand.

Spiky is very tolerant, but Aurora herself is a little embarrassed, she is the kind of character who wants to do her best no matter what, and to some extent she can be regarded as competing with herself. She didn't want Spike to repeat her ability, and would rather waste her ability a few more times, although Spike didn't mind.

Aurora unleashed her abilities on several other bottles of mineral water, bottle after bottle.

The first bottle was still a little too forceful, and the water in the bottle quickly froze, and due to the expansion of the volume, a small icicle gushed out of the mouth of the bottle.

The second bottle was more successful, the water in the bottle did not freeze, but only cooled down.

Spikelets also release the ability to sense the surface tension of this bottle of water.

"Uh......" she looked at Aurora, a little embarrassed.

Aurora looked slightly embarrassed, guessed what was wrong, and asked, "What's wrong?"

"The temperature seems to be unstable, causing the surface tension of the water to rise and fall...... Ah, it's not your problem, it's mine, I haven't practiced this temperature lowering mode yet!" Kosui hurriedly explained.

It's spring, the temperature is gradually rising, and it will soon be the turn of spring and summer, and the temperature can be close to 20 degrees Celsius at noon during the day, and it will be even higher if it is a place where the sun is directly shining.

The temperature of the water in the bottle is the same as the air temperature, but when the water temperature is lowered, the heat is transferred from the air to the water, creating a repeated tug-of-war.

When Spikelet puts the jelly water ball on Rafite's head, Rafite's body temperature will also increase the temperature of the water, but the human body temperature is basically constant, which is considered constant, and the curve of water temperature rise is relatively smooth, and the spikelet has time to adjust at any time, and the interaction of Aurora's strong refrigeration, air temperature, and sunlight makes the curve of water temperature like a violently undulating sawtooth, which makes Spikelet at a loss.

Aurora understands that the main responsibility lies with herself, she not only has to lower the water temperature, the lower the water temperature, the stronger the surface strength, but not to make the water temperature lower than freezing, but also to make the water temperature both low and stable, always adjust with the temperature and sunlight, Xiao Sui did not say directly because this difficulty is very high, the temperature is different from day to day, the temperature is different from time to hour, and it is completely different with or without direct sunlight, and her refrigeration temperature is difficult to be as constant as the body temperature of the human body, and it is difficult to get three variables that change at the same time.

But if she just throws in the towel, she's not Aurora.

Without saying a word, she silently used her abilities on another bottle of water again, this time trying to control her abilities and fine-tune them to adapt to the changes in temperature and sunlight.

Soon, fine beads of sweat appeared on her forehead, and such an extremely delicate operation was no more labor-saving than her going all out to condense ice crystals on a large scale, and it could even be said that it was more laborious, and her spirit had to maintain a higher degree of concentration.

Xiao Sui looked at her sympathetically, because she herself had experienced the process of adjusting her ability from macro to micro, and she had exploded all her potential under the threat of Mei Yibai's life, and she had done it in a short period of time, if it was replaced by the current stress-free situation, she might not be able to do it.

Several bottles of water repeatedly hovered between cooling and warming, and large droplets of water condensed on the outer walls of the bottles, and the small droplets converged into large droplets, and then dripped down, like beads of Aurora's sweat.

Xiaosui persuaded Aurora to rest for a while several times, don't be in such a hurry, it's okay to try again in a few days, don't push yourself too hard, but Aurora was unmoved and kept trying repeatedly.

Xiao Sui and Chio glanced at each other, there was nothing to do with Aurora, and at the same time they admired her willpower.

After about half an hour, Aurora's sweat was all on her eyelashes, and then she suddenly breathed a sigh of relief and said, "It seems to be okay." ”

"Really? Great!"

Xiao Sui was surprised and delighted, Aurora actually got three temperature variables in such a short time?

"Three variables, plus one constant – the person's body temperature. ”

Aoro stretched his hand and picked up a bottle of mineral water and took a few sips.

"What do you mean?" Spike was stunned.

"Your trick is against people, attached to the human body, it will definitely be affected by the person's body temperature, fortunately, the person's body temperature is constant, so I added the person's body temperature as a constant and added it to the calculation, anyway, it won't cost too much extra calculation. Aurora handed the half-drunk bottle of mineral water to Spike.

Xiao Sui took it in a daze, at first she thought that Aurora would let her drink it, but after a while, she suddenly understood what she meant—this half bottle of mineral water was held in her hand, and the temperature did not change?

Aurora completed the most difficult part of the two's cooperation by herself, leaving the easiest part for Spike, the low temperature and constant water, which is most conducive to Spike's ability.

It's amazing......

Koho and Chio sighed from the bottom of their hearts, they really deserve to be Aurora, the idol of the academy, and this will and sense of responsibility alone is not something that everyone in the young students can do.

Aurora stopped controlling the temperature of the bottle of water, rested for a while, and waited for her mental and physical strength to recover a little, and said to Spike, "Try it again now." ”

"Good. ”

Spike's confidence increased this time, and she picked up a bottle of water again, the mouth of the bottle tilted, and a stream of water trickled down.

Aurora's eyes were fixed on the water, precisely controlling the temperature of the entire stream so that it was low enough not to freeze, and the surface tension of the water was an additional bonus at low temperatures.

She doesn't know what Spike wants to experiment, but as a teammate, she has to give her teammates enough trust, and she just needs to provide support as much as possible, and there is no need to ask anything else.

Under the gaze of several people, a peculiar scene appeared.

After this water touched the ground, it should have splashed, then flowed on the floor, and was eventually absorbed by the floor, but at this time, the water was like a leather ball, after touching the ground, it only turned into a round pie shape, and did not disperse, stubbornly resisting the absorption of the floor, which reminded them of mercury, but the water is not as heavy as mercury, and it will not be pervasive after landing.

This is something that Spike has never done, and Aurora's cooling has helped her further improve her abilities while maintaining her own strength.

"Congratulations!" Aurora saw the joy in Spike's eyes.

"Thank you, I wouldn't have been able to do it without Aurora's help!"

Jiang Chanji also seemed to see the mystery in it, he had seen the water balloon used by Xiao Sui before, and this time there was a significant change.

Only Qianyang was still confused, she didn't see anything strange about these water droplets rolling on the ground, and pulled Xiaosui to ask.

"The water polo itself is not important, the important thing is that Aurora has helped me to push the limits of my abilities even further, for example, if I could only freeze 1 liter of fruit before, now I ...... Well, let me think about it, maybe one and a half liters in the extreme case. Spike explained.

Qianyang still didn't understand too much, but he was also happy for his friend, "Isn't that Xiaosui very powerful?"

"It's not very powerful, at most it's just some small tricks, and it can't be elegant. Xiao Sui said modestly, "It can't compare to the really powerful abilities of Aurora or Mio." ”

"No, Xiaosui, don't be presumptuous, they all say that water can carry a boat and capsize a boat, and your water control ability still has a lot of potential to be tapped. Aurora said.

"Haha, it would be nice if it was true~" Xiao Sui was not greedy, and smiled heartily.

"Senior Sister Aurora is right, I feel that although your water control ability is good, Senior Sister Xiaosui, in general, it may just be just entering the room. ”

After the experiment began, Zixuan, who had been watching intently and did not speak, suddenly spoke.

Everyone was stunned when they heard this, because the tone of this sentence was too big, if it was said by any teacher, everyone would not question the teacher's judgment, or if it was Aurora who said it, everyone would think that she must be based on reason out of the importance of her strength, but this sentence actually came out of the mouth of an ordinary student like Zixuan who had no extraordinary ability, and she was still so young...... It's hard to be convinced.

Even Aurora's words just now are actually mostly words of encouragement.

"Haha! Sister Zixuan said well, I will work harder!" Xiao Sui didn't want to argue about anything, and wanted to change the topic to another one after a haha.

Miao held on to the words, "Senior Sister Zixuan, I can't take this as if I didn't hear it, why do you want to agree with Olara's words? It's too late to admit your mistake now, otherwise be careful that the favorability in your Sister Mio's heart will drop greatly~!"

Zixuan squatted down, and under everyone's gaze, she picked up a small pebble casually and scratched it on the floor, and everyone saw that she had drawn a few strange mathematical symbols to form two or three equations, and then smeared them a few times.

Except for Aurora, who could see some clues from it, the others didn't understand what she was doing, not even what constants those symbols represented.

Aurora's eyes widened in surprise, "You...... That's how you calculate the closed curve integral?"

"No, it's so-so. Zixuan threw away the pebble, patted the dust on her hand and stood up, and said to Xiao Sui: "Senior Sister Xiao Sui, I just calculated that the surface tension limit of water can carry a tank at most without the intervention of extraordinary ability. ”

Xiao Sui and everyone were dumbfounded, one was shocked by the answer given by Zixuan, and the other was shocked that she had calculated such a complicated problem after a few strokes on the ground in such a short time.

Zixuan thought they didn't understand, and explained: "Have you all seen mosquitoes parked on the water? When the water is at its limit, it can hold a tank like a mosquito on the water, and it is an ordinary tank, not an amphibious tank, or an object of the weight and volume of a tank." ”

Everyone is all the same: It's not that I don't believe you, it's the .gif we all want to open our eyes.

"I heard Jiang Chanji say, Senior Sister Xiaosui, your ability can at least hold up the weight of an ordinary person, although it is very good, but there is still a lot of potential to be tapped. In order to let the water hold up the tank, it is necessary to achieve the limit of various internal and external conditions, and pure water cannot be used, specific substances must be mixed into the water to change the surface tension of the water, in this case, the theoretical limit calculated, of course, it is very difficult to do, it is almost impossible to rely only on the actual conditions, but with the intervention of extraordinary ability, maybe Sister Koho can really do it!"
