In the training camp not far from the simulated prisoner-of-war camp, 12 members of the escort special operations team were looking at the room opposite with interest.

Just after the exercise, they came here to rest and prepare for the next stage of training.

The members of the escort special forces team saw the members of the Thunder Commando with their own eyes and brought the female soldiers here one by one.

Seeing the female soldiers being driven into the room and not making any noise for a long time, Wu Zhe couldn't help but be surprised.

He looked at Shao Bing beside him with confusion and said, "Hey, brother cold-faced, are you talking about the lightning person venting his personal anger?"

"Although it is true that those female soldiers lost the face of their instructors in the exercise, it is reasonable. There is no need to punish them with such a big fanfare, right?"

A few days ago, when Wu Zhe and Shao Bing were training together at the base under the naval combat situation of the headquarters combat department, they were already very good.

After all, the two have the same old leader - Su Qiuyue, and it is easy to get together.

Now when they call each other, Team Shao has long since disappeared, Team Wu’s politeness has been called directly.

Wu Zhe's code name is naturally hoe, while Shao Bing's code name has some twists and turns.

In fact, his code name was originally Big Wolf.

But Wu Zhe felt that this guy was usually serious and had to give him the title of "Brother Cold Face".

Shao Bing is lonely and doesn't care about this either.

In this way, he, the "cold-faced brother", was confirmed in the 12-person team.

The two team leaders got along so well, so naturally the other team members were not very reserved.

When Wu Zhe asked Shao Bing, Chengcai, Xu Sanduo, and Leng Feng were all standing aside and paying attention.

"Hoe, each special forces have their own training methods, which is nothing strange."

Shao Bing said calmly, "We came here to train with the other party's 'treasure land', and other things have nothing to do with me. If you feel that you can't see the hoe and want a hero to save the beauty, I won't stop you..."

After hearing this, Wu Zhe couldn't help rolling his eyes at the old man.

"Brother Cold Face, I don't believe you really have no feelings at all!"

Wu Zhe put his hands in his waist and said, "I just heard from the madman. During the exercise, there were 26 female soldiers, and there were 6 of them hanging on your hands. Seeing that they were punished for your ruthless actions, wouldn't your conscience hurt?"

Wu Zhe's words are naturally joking.

Shao Bing has already figured out the temperament of this young lieutenant colonel these days, so he naturally won't care about it.

In fact, he couldn't care.

After all, the other person's military rank and position are still above him, so he really has nothing to do.

At that moment, Shao Bing quickly turned his gaze to the other side and said lightly: "If you want to watch the show, just continue watching. I'll continue to review..."

Wu Zhe whined and said disrespectfully: "Okay, just review it, I'm just lazy."

Indeed, for Wu Zhe, today's exercise really has no technical content.

Recalling the show is just a formality.

Shao Bing is meticulous in his work and meticulous in his work. It would be better for him to do it.

As Leng Feng watched his captain enter the house, he couldn't help but speak to Wu Zhe.

"Chief~ No, hoe. I have never understood that you are so knowledgeable, why are you so poor in your name?"

Leng Feng complained: "What kind of broken code has you given to our Team Shao? Isn't it good to add two words to call Cold-faced Killer?"

After Chengcai, Xu Sanduo nodded and expressed his deep agreement when he heard this.

Wu Zhe glanced at Leng Feng and said in a playful tone: "Madman, don't blame me for not reminding you. This code name is simpler, the better."

"And the most taboo thing is that even if you add words casually, it is easy to make jokes."

Leng Feng was stunned for a moment, then asked in confusion: "Will you make a joke if you add words casually? Is it so exaggerated?"

Wu Zhe shrugged and said, "Just say you Team Shao, I'll give him a cold-faced nickname, you don't think it sounds nice. Add two words to become a cold-faced killer."

"But if 41 and 42 are not good, they will add two more words - Goryeo, the taste will change suddenly! Are you thinking about this?

"Add two more words, Goryeo? Goryeo Cold-faced Killer? Damn!"

Leng Feng finally realized it now and couldn't help but swear.

When Xu Sanduo thought of the interesting thing, he couldn't help laughing.

Wu Zhe blinked his eyes and said with a smile: "So, Brother Cold-faced, Brother Cold-faced, it's great."

Leng Feng finally knew how quickly Wu Zhe was thinking about it, and couldn't help but give him a thumbs up: "You are amazing!"

"Okay, brother, let's continue to watch the show. The people from this thunder and lightning commando have left the female soldiers almost the same. I guess it's about to change!"

After hearing this, Leng Feng and Chengcai, Xu Sanduo's expression tightened at the same time.

Although Wu Zhe, the team leader, sometimes has too little airs in the leadership team, no one will question his judgment and IQ.

Since he made a judgment, things were likely to be based on his inference.

...

"Hey, I'm almost thinking, right? Are there anyone willing to explain the problem truthfully?"

Outside the small room, Yan Gang asked carelessly.

"No, we can't say anything!"

The female soldiers in the room said in unison.

"Very good! Very backbone!"

Yan Gang praised him and said to Niu Yi next to him: "Give them some appetizers!"

"clear!"

Niu Yi responded and immediately stuffed a sprayer into the window.

As the switch in his hand turned on, waves of white smoke immediately erupted from the sprayer.

Not far away, Wu Zhe and others couldn't help looking at each other when they saw this scene.

"What are they doing? Are they crazy? That's dry ice! It'll freeze to death!"

Seeing this, Leng Feng couldn't help but speak.

“Not not…”

Wu Zhe shook his head and explained, "Dry ice sublimated by absorbing the surrounding heat. The sublimation temperature of dry ice in the atmosphere is -78.9℃, and its latent heat is 137 calories per kilogram."

"But the heat required to rise from -78.9°C to 0°C is 16kcal/kg. It takes more heat to heat to 0°C than 16kcal. The cooling force of cooling to 0°C is equivalent to 153kcal per kilogram."

"The height of this room is about 2 meters and has an area of ​​25 square meters. To reach the point of death, at least 3 cubic meters of dry ice is needed."

"Obviously, the people from the Thunder Commando did not intend to freeze the fire phoenixes to death..."

Listening to Wu Zhe's accurate data flow, Leng Feng couldn't help but open his mouth: "Can the hoe be a little bit popular? This is too profound!"

"You are right, just say so much about what will happen after you enter the dry ice!"

Behind the few people, Shao Bing's voice suddenly sounded.

Wu Zhe turned his head in surprise and looked at Shao Bing, and couldn't help but say curiously: "Brother Cold Face, haven't you gone to review the matter?"

Shao Bing said calmly: "Watch the endurance of these female soldiers and can also provide some data for the review."

Wu Zhe looked at the other party with disbelief, but still expressed his judgment.

"At present, what the Lightning Commando uses for female soldiers is the training theory of the limits of their bodies. They use the heat absorbed by dry ice to create training problems for female soldiers."

"This first level is so difficult. I guess these fire phoenixes are in danger!"

After hearing this, Shao Bing, Leng Feng, Chengcai didn't say anything, and he agreed very much.

Xu Sanduo scratched his head and couldn't help asking: "What does dry ice sublimation mean? Why don't the people of Thunder and Lightning directly use ice?"

After hearing Xu Sanduo's question, Wu Zhe explained it in detail.

"This sublimation means that the solid does not pass through the liquid state and directly turns into gas. The temperature remains unchanged. The heat required to turn from solid into gas is called latent heat, and the heat required for sublimation is called sublimation heat."

"Taking heat from the surrounding area will cause the surrounding temperature to drop, so the greater the latent heat, the greater the cooling capacity, and the better the effect it is as a coolant."

"Compared with ice, the cooling power under the same volume is theoretically about 3.3 times that of ice."

Speaking of this, Wu Zhe spread his hands and said, "So, of course, it's better to use dry ice."

When Xu Sanduo heard this, he finally realized it.

Shao Bing, who was standing by, seemed to have thought of something and couldn't help asking: "But there is a problem! The main component of dry ice is carbon dioxide. If it is inhaled too much, it will make people feel dizzy. If it exceeds the amount, it is possible to even die directly."

"Can they control this amount, the Thunder Commando?"

After hearing his question, Wu Zhe said with a relaxed look on his face: "Don't worry, the situation you mentioned cannot happen. Because the sealing of this room does not meet the harsh requirements. So what you are worried about will definitely not happen."

When Shao Bing heard this, he finally breathed a little relieved.

Thinking of the process of easily taking down the Fire Phoenixes before, he couldn't help but mutter.

"Ho, what's the point of having a female special forces above? If they really go to the battlefield, can they do it?"
