The bodies of six Delta Special Forces soldiers were housed in a house in the middle of a military base.

These people hadn't seen Wen Ming before, but Donus had seen them, and when he was selling tactical goggles, he had trained people in the Delta Special Forces.

At this time, lying on the cold iron bed were 6 of the 12-person combat team that had first been in contact with training and used tactical goggles for exercises under the command of Donnas.

Donnas still vividly remembers the perspective he could see as he watched these men with tactical goggles on their heads, as if he were playing a role-playing game, directing them to practice and fight. He was even able to name three of them, and the other three, although they couldn't be named, had communicated with each other.

"Is this war?"

Donus's heart for adventure has completely cooled down at this time. Adventure is adventure, and when the fragility of life starts to daunt, adventure is not so interesting.

Colonel Hans shook his head and said, "This is not a war, if it is a real war, we will not even see their corpses." ”

Small-scale ground contact warfare is indeed not a real war.

Aaron Martin followed at this time, because the place where their luggage was stored was near this barracks.

"It's true that this is not a war, but we still have to fight back."

After saying this, Aaron Martin patted Hans on the shoulder, the feeling of losing his comrade-in-arms, he also had it.

Wen Ming didn't speak, but carefully observed the six corpses in front of him.

"We have tested their bodies, and the cause of death is that they were exposed to ultra-low temperatures in an instant, which caused their bodily functions to be completely destroyed. That is, they were frozen to death. ”

But when they found those...... After the ghosts, those ghosts attack them, and then the time of their death is only about 1 second. I really can't think of how there is such a weapon in this world that can freeze a heavily armed soldier to death in 1 second. ”

Wen Ming felt a little disgusting at this time, although he had killed people, and it was not what the CIA thought had killed a person. But when faced with these 6 corpses, I still couldn't help but feel sick.

Because, the facial expressions of these people are very frightened.

The ultra-low temperature killed them in an instant, leaving their expressions behind, even after more than a day had passed, there was still no change.

When I watched this movie in my last life, Wen Ming didn't have too many feelings about the frightened expressions on the screen. Even the fierce ghosts in those horror movies, none of them are more touching than what he sees now.

A living person died, not an actor in the movie.

Holding back the discomfort, Wen Ming said: "As far as I know, if there is enough liquid nitrogen, it can also cause such lethality. ”

Fran nodded and said, "Yes, but we have tested the place where they were killed, and there is no sign of a large amount of liquid nitrogen there." Moreover, if liquid nitrogen is used, it should be soaked in liquid nitrogen like a bath. ”

Wen Ming said: "The temperature of liquid nitrogen is minus 196 degrees, and if our skin is directly exposed to liquid nitrogen, as long as it does not exceed two seconds, there will be no problems. You have found no signs of liquid nitrogen on the scene, and they only have a second, or even less than a second, from the time they are attacked to their death. Well, there is only one truth. ”

After a pause, Wen Ming saw that no one at the scene understood this stalk, so he could only continue helplessly: "That is, they have come into contact with absolute zero." ”

Everyone knows the term absolute zero, but they don't know the concept in it.

So in the puzzled eyes of Hans and Fran, Donus explained: "Absolute zero does not actually exist, and so far the scientific community has not found that the temperature of anything is absolute zero, only infinitely close to absolute zero." ”

"In the state of absolute zero, the atoms, molecules and other particles inside the substance have almost no kinetic energy at all, which means that their energy will not be lost and will not evaporate. But if there is a substance with absolute zero, then its temperature is minus 273.5 degrees. ”

"We can be exposed to liquid nitrogen without damage, and the contact time must be less than two seconds. However, the temperature of liquid nitrogen is only minus 196 degrees. If it is a matter of absolute zero, then it doesn't even take a second for us to die. And the state of death, it is quite possible to ...... with them The same. ”

The people Donners was talking about were naturally the six American GIs lying in this barracks.

After explaining the absolute zero, Donus asked curiously, "But what if you attack the soldiers...... Ghost? If they are in absolute zero, how do they move? As you can see from the video, they pounced on the soldiers from a short distance, and that's what they did. As long as an action is made, there is kinetic energy, and the atoms, molecules, and other particles inside it are moving. The Wendy level of matter is based on the speed of the movement of the particles inside them, and when they move, it cannot be absolute zero. ”

Wen Ming nodded and said, "Yes, if they move, it really can't be absolute zero." I didn't expect you, a genius majoring in computer science, to know so much about physics. ”

Donus scratched his head in embarrassment and said, "These, it seems to be common sense." ”

Hans, Fran, and Aaron Martin next to him all looked at each other, if this kind of knowledge is common sense, then aren't they even normal people?

Wen Ming said: "Matter is all in motion, there is no absolutely static matter, or there is, but we humans have not yet discovered it. But everything is relative, just like us humans, we can walk, we can run, and of course we can sit quietly. ”

"Although in this process, our bodies are constantly moving internally, externally, we are in two states: moving and stationary."

Donnas suddenly asked, "Boss, you mean, ghosts can stop themselves, no, they can be still, so that their temperature is infinitely close to absolute zero." ”

Wen Ming nodded and said, "Yes, from what we know so far, this ghost is composed of some unknown substance, just like air and light. Therefore, the weapons of the soldiers could not harm them. This substance is capable of making it absolutely stationary, and when it pounces on the soldiers, they turn themselves into absolute zero matter in an instant, causing the soldiers to freeze to death in a second. ”

Donus suddenly frowned and muttered, "I know...... I know, I've heard of this substance, but why can't I remember? ”

Wen Ming directly said his answer: "Bose-Einstein condensate, 80 years ago, Einstein predicted a new state of matter. ”

Donus suddenly realized and shouted: "Yes, it is the Bose-Einstein condensate, and it is the same particle as the condensation state." ”

Hans, Aaron Martin, and Fran listened inexplicably, they really couldn't understand the meaning of these unfamiliar terms. And how could Einstein predict it 80 years ago?

Could it be that Einstein was not a scientist, but a prophet?

Wen Ming looked at everyone's puzzlement and laughed. Although it was not appropriate to laugh on such an occasion, he had obtained the known conditions, so he could directly say the result that he knew in advance.

"You don't need to care about the meaning of these terms, you don't need to know how they exist, you just need to know that we have a way to attack them."

Hans became excited, but frowned again in an instant, as he noticed the point in Wen Ming's words.

"Mr. Wen Ming, you mean to attack them? Instead of...... Destroy them? ”

Wen Ming said: "Yes, at the moment we can only attack them, as for destroying them. As things stand, they cannot be eliminated. ”
