As the sound of his magician chanting a spell "came out", a cloud of 0°C cold air spread out in the space in front of him.

Suddenly, Wang Qi felt as if he had fallen into the ice and snow, and he couldn't help but shiver. The two naked arms also began to get goosebumps at a speed that was visible to the naked eye.

This extremely cold air that made people feel extremely cold lasted for at least six or seven seconds before it gradually reached thermodynamic equilibrium under the erosion of the surrounding thermal environment and slowly disappeared.

"It's done?" Wang Qi lowered his head, looking at the goosebumps on his two arms that had not completely dissipated, and knew that the "portable air conditioner" he had conceived was basically completed.

Subsequently, he conducted a second trial.

This time, he turned up the temperature in the lab from 0°C to 16°C. Because the lowest temperature that can be adjusted by the air conditioner in reality is 16 °C - it's not that it can't be cooler, but it's not necessary, below 16 °C, people will feel very uncomfortable, just like the 0 °C cold air he just made, which made him shiver with cold and goosebumps all over his body.

16°C is much better, and the refrigeration lasts a lot shorter, probably only for three or four seconds.

But that's not enough.

He has to turn on the "portable air conditioner" during military training, and he can't let the people around him "enjoy". Therefore, the consideration of refrigeration effect and duration is secondary, and the most important thing is not to let the people around you find that there is a serious, uncommon sense temperature difference around you, and not to let others suddenly feel "a gust of cold wind blowing in the face".

He needs to be "happy alone", not "happy with all".

In the following time, Wang Qi began the third, fourth, and fifth ...... has been experimenting more than a dozen times, and the "portable air conditioner" that can be used in front of the public is basically satisfactory to him.

At present, the final molded version of the "portable air conditioner" is a "humanoid air mass" with his height as the standard, a temperature of 26 °C, and a thickness of 10 centimeters.

During this time, although Wang Qi did not discover other new functions of the cube, he still had a certain expansion in his previous cognition.

For example, he used to think that a cube could not hold objects larger than one cube, and subconsciously thought that the length, width and height of the object had to be within one meter. Objects that are more than one meter, like a two-meter-long clothes pole, will definitely not fit, and even if the body diagonal line of the cube is put into it, it will exceed the value of the cube body diagonal "root number 3" 1.732.

However, the day before yesterday when he went to Carrefour with a few guys to purchase, he dragged the clothes pole he wanted to buy and muttered in a low voice, "If only the cube could fit this clothes pole in", as a result, the clothes pole in his hand "swished" and disappeared directly, which startled him.

From this, Wang Qi understood that the cube is not always a "cube", and it can also be transformed according to the needs of reality.

For example, even a twenty-meter-long steel bar can be put in, but the cube is afraid that it will become a long cylinder.

Since the cube can be transformed, there is no need for Wang Qi to be rigid about the shape when summoning the cold air mass.

So, he directly copied a square icon on the front of the cube he called "desktop", that is, the "boot screen" that he saw every time he opened the cube, which already had several icons, and named it "air-conditioned room", and then used his consciousness to prop it up and change its shape, becoming a shape roughly humanoid, about 10 centimeters thick.

This thing looks big, and it is nearly 1.8 meters tall, but the total volume is very small, occupying only about 1/20 of the entire cube. Because even if a 100-kilogram adult strong man is all pressed into meat puree, in terms of volume, it is at most 100 liters.

And one cube has a thousand liters!

This "humanoid air mass", which is based on his height and has a temperature of 26 °C, is released almost close to his nose when released.

And this kind of close-fitting release is also very effective, and you can feel the faint coolness almost instantly. The duration is also short, about two or three seconds, blowing on his body, and immediately harmonizing with the surrounding hot environment.

This "humanoid block of cold air" can also be released against his back, cooling the other side of his body, and the effect is the same.

Of course, everything has advantages and disadvantages, and if there is a spear, there is a shield, and the "portable air conditioner" that Wang Qi has made up is no exception. Its biggest disadvantage is that it lasts too shortly, and it needs to be released every two or three seconds to maintain the effect of continuous cooling.

Fortunately, he doesn't need to meditate to release and store objects, just a thought.

Otherwise, if he had to meditate for a long time and recite magic spells for half a day before sending a spell like some magic novels, then the "portable air conditioner" he made up would be a complete piece of rubbish, and it would take him less than a minute to exhaust him!

————————————

With the blessing of the "portable air conditioner", in the following military training that afternoon, Wang Qi was simply not too happy, and walked back and forth on the dusty dirt playground for a long time, and he didn't see a trace of sweat on his face.

Perhaps it was too carried away, and the abnormality on his body was quickly discovered by You Yu next to him.

"Seventh brother, what's wrong?Why do you feel that your face is not very good?Is it heat stroke?" Sweating profusely, the T-shirt on his body was even more wet, as if he was fished out of the water, You Yujian saw that Wang Qi next to him had no sweat on his face, and the T-shirt on his body was also dry and refreshing, so he immediately became concerned and thought he was suffering from heat stroke.

When Wang Qi heard You Yu's concern, he felt bad, and thought to himself, Nima pretended to be too much, and the boat capsized.

But with the "facts" in front of him, it was impossible for him to say that he was fine, so he only nodded with "weak energy" and said, "It's a little uncomfortable." In the afternoon, I felt a little chilly on my body inexplicably. ”

Seeing that Wang Qi was really sick, You Yu didn't care that he was standing in a military posture now, so he immediately touched Wang Qi's forehead and was surprised to find that the other party's forehead was cold. And he touched his arm, and it was cool, like a dead man. You Yu was taken aback, and immediately went out of the queue and shouted at several security guards who were hiding in the shade of the trees:

"Instructor, instructor, we have someone here suffering from heat stroke!"

Wang Qi wanted to say to You Yu that it didn't matter, he would just "grit his teeth and insist on insisting", but before he had time to speak, this guy was shocked and went to call the instructor. He couldn't ignore the kindness of others, in order to be realistic, he even lowered the temperature of the "portable air conditioner" directly to 0°C, and he continued to summon it in front of and behind him without money, until a guy behind him suddenly said, "Hey, why do you feel cooler all of a sudden? It's not going to rain, is it?", and then stopped, reducing the speed of summoning cold air.

In this way, when the two security guards didn't even have time to dust off the ashes on their buttocks and hurriedly ran over to check the situation, Wang Qi in front of them was already pale in complexion, his lips were purple, and he was covered with goosebumps all over his body.
