I turned around and saw that Xu Meijing's box was constantly pouring water into it, it turned out that the top pipe was used for filling water, and the water flowed down the pipe from the top of Xu Meijing's head to the heel, and in the blink of an eye, Xu Meijing poured it into a soaked soup chicken.

"Zheng Yan! It's ice water! Ice water! It's actually ice water! Xu Meijing covered her body with her hands and shivered inside the glass box, and I could clearly see a layer of goosebumps jumping out of her face, and her feet were bouncing around in it.

At that time, Xu Meijing chose the money bag among a basin of water and a money bag, but at this moment the life-saving water source has become a tool to take her life, although the water pipe is only the size of an arm, but the space of the glass box is limited, according to this water flow speed, the water tank can be filled in three minutes at most, and the final result is to drown Xu Meijing alive in the box.

The most perverted thing is that all the ice water is poured in, the body temperature of a normal person is about 37 degrees 8, soaking in the water at zero degrees Celsius is an extremely dangerous behavior, based on the prediction of normal people's physique, Xu Meijing can't stay up for five minutes at most in the ice water, and the various organs in the body will be greatly atrophied and metabolized, and even more serious will lead to organ failure.

In other words, I will rescue Xu Meijing from the box within at least five minutes, otherwise Xu Meijing will end up either dead or disabled.

As I was thinking, the water pipe had been filled with thirty centimeters of ice water, and the ice water touched the room temperature glass while creating a layer of cold air, Xu Meijing waved her hand at me for help inside: "Zheng Yan!" I'm freezing to death! Find a hammer to break this glass! I beg you! I don't want to die! ”

I stood still and didn't move, but I brought an iron axe from the garage, but this method is basically a waste of time, this kind of glass axe is impossible to hammer open, unless it is an industrial mechanical hammer, the pressure is greater than the compressive index of glass, it is impossible to get that kind of mechanical hammer at the moment.

I used to hear my dad talk about the common sense of tempered glass, saying that this kind of glass is afraid of scratching and not afraid of smashing, in industrial design, one thing drops a thing, no matter how hard the glass is afraid of diamond diamonds, if you want to solve the mystery of the tempered cage in front of you, you must find an object that is harder than tempered glass in a short time, so that it is possible to cut the tempered glass.

What is harder than glass? My mind was spinning for answers, and the best answer was diamond diamond, followed by tungsten steel, steel, and other materials, followed by iron, but iron is less hard than glass.

Iron?

I suddenly had a clever idea, although the hardness of iron is not as hard as that of glass, but the heat treated iron is different, and its hardness has exceeded the original iron several times, enough to cover the tempered glass in front of me! Isn't there ready-made wrought iron in the No. 9 kitchen warehouse!

I turned around and ran towards the No. 9 warehouse, and before I could take two steps, Gu Meijuan screamed, she suddenly pointed to the glass under her feet, and shouted in horror: "Zheng Yan, look! Look at this glass ......."

I glanced in the direction of her finger, and gasped in my heart, the glass under Gu Meijuan's feet actually changed color!

I saw that the piece of glass under her feet emitted a fluorescent glow, and I knew at a glance what was going on, and it was the cable under the glass that was heating the glass!

When the cable heats the glass, the temperature inside the box will gradually increase, which is compared to the window heating function we usually see, the thermal conductivity of the glass is very fast, and if you add a high-power power output, the temperature will soar in a short time.

In this way, this transparent glass box is like the principle of boiling a frog in warm water, and it will not kill Gu Meijuan in a short time, but as time goes by, the temperature will get higher and higher, the temperature in the box will get higher and higher, and the oxygen will disappear, and the end can almost be predicted in advance, Gu Meijuan will either be suffocated or roasted to death in the end, and the torment and urging can be imagined.

At this moment, I finally understood the meaning of the two heavens of ice and fire in Du Jiang's mouth, Gu Meijuan pushed her friend into the fire pit, and the end for her was to roast with fire, Xu Meijing was reluctant to save her classmates with a basin of water, Du Jiang used ice water to punish him, one ice and one fire, and at the same time punished two treacherous people, which also vividly interpreted the meaning of "ice and fire".

"Zheng Yan save me! Du Jiang wants to burn me! Gu Meijuan had already sensed the serious consequences and cried at me.

"Zheng Yan, I'...... I'm drowning...... You can't leave me......" Xu Meijing's eyes were also full of tears, and the ice water had already submerged to her knees, and the whole person was wet, and she couldn't tell whether there were water droplets or tears on her face.

The voices of the two women crying for help came and went, I was also anxious in the middle of the aisle, I first touched Gu Meijuan's glass temperature, the glass surface was about twenty or thirty degrees, Gu Meijuan inside was already sweating profusely, sweat was overflowing from her forehead and nose, she had already pulled the zipper of her skirt, revealing her fair and immature skin.

The limit heat that the human body can accept is seventy heights, and according to the speed of diversion, the time to stay with me is between three minutes and five minutes, and Xu Meijing's limit is also five minutes, and I can only save one of the two women? Who should I save? How to save?

"Hot hot hot! I can't stand it anymore! Zheng Yan! I can't breathe! Gu Meijuan stood in it and was shaky, almost unable to hold on.

I reflexively thought of a way to alleviate it, the heat filament of the glass surface! There is a copper heat wire embedded in the surface! Let's start with these heat wires!

I held the iron axe in the auto repair room, and used the strength to eat milk is a wild chop, and after a while, all the heat conduction wires on the glass surface were cut off, which weakened the thermal conductivity function of the firebox to a certain extent, but I knew that this was just a prayer for a relieving effect, and the power supply itself was still continuing to supply power and heating, but I extended the time process in the middle a little, and the symptoms were not cured, and there had to be other ways to save Gu Meijuan.

Temporarily solved Gu Meijuan's crisis, I hurriedly ran back to the No. 9 kitchen warehouse, returned to the edge of the head teacher's half-cut corpse, didn't have time to care about the bloody cruelty of the scene, picked up the half-cut iron chain buckle on the ground, and it happened that there was an inverted triangle diamond-shaped connecting block in the middle of the button, and it was perfect to use this connecting block to scratch the glass.

When I returned to the food room again, the situation was worse than I imagined, Gu Meijuan's fire box kept emitting heat, she stripped off her clothes, only wore black underwear, her fair skin had begun to show a flushed color, she put her skirt on the ground to block the heat, even though she was still suffering, she was crying and stomping her feet in the hot air.

The situation in Xu Meijing's refrigerator is not optimistic, the water level of the ice water has reached her chest, her expression is even more ugly than Gu Meijuan, this time she has frozen her lips purple, her face is bloodless, she can't speak, and she can only tremble at this moment.

I quickly took out the wrought iron buckle I found, and struck it hard with the axe, the effect was as I expected, and the wrought iron cut the glass crystal out of a small pit the size of a fingernail in the process of striking.

This shows that the hardness of wrought iron buckles is more than the tempered glass itself, and the tempered glass should be able to be broken according to this trend.

But I also made a difficulty, once I tried my best to break Xu Meijing's tempered glass, it meant that I couldn't spread my time, I couldn't take care of Gu Meijuan, Du Jiang was right, I only had one chance, I could only take one of the two women!

"Gollum ......"

At this critical moment, Xu Meijing couldn't hold on, one of her legs shook in it, and then she sank down and drank two sips of ice water, probably the cold chill stimulated her, and the strong desire to survive made her stand up quickly, staring at me with frightened eyes and waving at me.

"Zheng Yan! You can't just watch me burn to death! Gu Meijuan on the other side shouted even more fiercely.

I looked back and was instantly shocked by what I saw, and even the axe in my hand fell down with it.
