Liquid nitrogen, nitrogen in a liquid state.

It is inert, colorless, odorless, non-corrosive, non-flammable, and has extremely low temperatures. Nitrogen makes up the majority of the atmosphere (78.03% by volume and 75.5% by weight).

Nitrogen is inactive and does not support combustion. When vaporized, a large amount of endothermic contact causes frostbite!

At atmospheric pressure, the liquid nitrogen temperature is -196°C!

Skin exposure to liquid nitrogen can cause frostbite. If the nitrogen produced by vaporization at atmospheric pressure is excessive, the partial pressure of oxygen in the air can drop, and in extreme cases, it may cause hypoxic asphyxia.

Although nitrogen is not an instant and lethal gas, the impact it has on the special combat team at this moment is huge!

From the moment the cylinder burst open, the white smoke spread out in the passage, spreading all the way to the extreme depths of the passage, and the icy chill came to the face and poured into the various rooms where the team members were hiding!

Thanks to the fact that this is the nitrogen that has been vaporized, if a person steps on the nitrogen of the liquid, the soles of his feet will be instantly frostbitten, causing the soles of the feet to fall off and the flesh of the belt, leaving only white bones!

Although the current situation is not so serious, the rapidly decreasing temperature makes everyone shiver, and the ultra-low temperature of minus 200 degrees Celsius is not something that normal life forms can resist, not to mention that the current special combat team has taken off its winter clothes.

The direct effect of the cold is the sluggishness of the human body's movements, and the blood circulation can be reduced in a short period of time due to the extremely low temperature!

Since Wei San was in the middle of the team, the previous cold gun, including the current nitrogen eruption, was not aware of it in advance, and his super sense of crisis did not play its role this time, Wei San, who turned over and entered the ward, hurriedly pulled up the bedding on the hospital bed, and reminded loudly: "Don't come into contact with those gases head-on, you won't get frostbite!" ”

Jia Mingzhong took the lead after the gas eruption: "Huh, haha...... How does this taste, let's be cool! ”

Ma Youde, who was already bleeding, was still chattering in his teeth while wrapped in the quilt, but just like that, Ma Youde didn't forget to scold back: "You mad dog, I'll kill you later!" ”

Wei San: "Be careful, they're coming!" ”

Taking advantage of the eruption of liquid nitrogen, the first unit rushed to this side, and the stinger was now suddenly exposed to this extreme ice environment, and it was difficult to adapt to the temperature change, and the sneezing sound sounded repeatedly.

The blood circulation slowed down, which led to a sluggish reaction, and the rhythm of shooting back was also slowed down, so that the first unit instantly advanced the distance between each other to only more than twenty meters, Wei San appeared from the door, and after putting down one person, he dodged back into the room, and the bullets fired from the opposite side couldn't help but dodge!

After being reminded by Wei San, most of the team members counterattacked, and under the fierce gunfight, several people were killed in the first unit, and seven or eight players who were inflexible were also knocked down, and close confrontations were inevitable!

More than forty people advanced from the First Force, and they kept shooting into various rooms, disrupting the rhythm of the Stinger's defense, and at this time, more than a dozen round objects rolled into the passage with a gurgle, and exploded with a bang, blocking the attack of the First Force for a moment.

The flames from the grenade did not make the team feel the slightest warmth, and the white gas evaporated very slowly, and he affected the team members in the ward all the time.

Just when everyone tightened their bayonets and prepared to carry out a hand-to-hand kill, Wei San reminded them again.

Waisan: "Smoke bombs!" ”

With Wei San's reminder, white smoke began to appear inside and outside the ward, and thick smoke rose in the white mist, reducing the visibility to the point where you couldn't see your fingers, and this sudden scene made the people of the first unit who raided hesitate.

But at this time, they also hid in the ward, and they didn't have to worry about being hit by stray bullets, although stray bullets would not hit them, Chu Jian's knife could!

After the smoke cleared, Wei San and Chu Jian grabbed out of the ward first, and with the help of the thick smoke, they quickly touched the enemy, and under such visual conditions, no one could see anyone!

The close-range fight stimulated Wei San's heart to beat faster, and no matter how bold and calm a person was in such an environment, he would worry about whether a bullet would suddenly fly out of the smoke and blow his head out!

Although neither side is shooting, but both have their ears pricked up at the same time, and when the eyes lose their function, the sensitivity of the ears will naturally double.

Wei San and Chu Jian's steps were extremely light, so that when those people from the first unit found them, the two of them had already touched their eyes.

really touched the front of him, a member of the first unit, who was still listening carefully to the surrounding movements in the thick smoke, but suddenly found that a knife stabbed his face door from the smoke, so close that he didn't have time to react at all, and watched the knife stab into his eye socket.

Red represents the opening of the house, Chu Jian and Wei San respectively carried knives and guns into the ward where the first unit was located, the riot occurred, the soldiers in the ward knew that there was an enemy in their camp, but they couldn't see where the enemy was at all, they could only hear the screams of their own people and the sound of falling to the ground!

Where is the enemy? How many people came? Why aren't the gunshots heard?

The rest of the members of the first unit all had different questions, and the fog area that could not be dispelled by stretching out their hands became their nightmare!

Jia Mingzhong, who didn't know what was going on, only heard the screams of his own people, and hid in the distance in a hurry and shouted: "What? What happened?? ”

"Answer me!"

"We've been attacked!"

"Bastard, you're the ones who went to sneak attack, why were you attacked?"

"They are among us!"

"Ah~!"

"I can't see them~!"

"Come and save me!"

"Shoot, shoot!"

"But I can't see where the enemy is."

"Bang~Bang~Bang......"

Panicked gunshots rang out, and the first unit shot blindly in fear, but the bullets they fired did not hit the defenders at all, but hit their own people!

"Damn, you hit me!"

"Where are they? Where are they!!? ”

The ward was filled with the screams of Unit 1, and Brown shouted loudly in worry: "Don't panic, stay where you are, don't shoot again!" ”

When the gunfire stopped, two white lights suddenly lit up in the ward, and the dazzling white light reflected the figure of the person in the smoke, at this time Brown saw it in the distance, he saw a figure with a knife, and quickly stabbed the person with a rifle in the fog, Brown wanted to remind loudly, but only had time to say "no".

The man who was stabbed fell, so that Brown had to give the order to retreat: "Retreat, retreat!" ”

The agile leopard-like man cast a deep shadow on Brown, and it occurred to him that maybe it wasn't a good idea to be an enemy of these people.

Brown, who shouted and retreated, waited for rows of bullets fired at him, how could the Stingers who were slowly recovering in the extremely cold area let them go at this time.

Gunfire rang out, and the GIs who rushed out of the ward were overturned by more than a dozen people, and only four wounded GIs escaped with their lives and returned to their place where Brown Jamingzhong was.

Aren't Wei San and Chu Jian cold? They were cold, so after they stole into the ward, they just caused a little chaos, and then they hid, and when their bodies regained their flexibility, the killing of the two was revealed.

This kind of behavior of hiding in the enemy group, only a madman like them has the courage to come out~
