After leaving Baghdad, Canglong took the train that had just opened and went directly to Basra Province, which is also the only railway in Iraq and the only north-south transportation artery in Iraq, the only railway that crosses the north and south, connecting Baghdad at one end and Basra, the second largest city in Iraq, at the other.

Tang Long woke up when they left the Rashid Hotel, and on the way he proposed to Canglong to go back to China, because he couldn't stand the environment here in Iraq, but Canglong didn't allow it, but he didn't allow it, and he didn't know why, from leaving the Rashid Hotel to the time they took the train in disguise, Canglong didn't say a word.

For the snow leopard, it was too embarrassing for them to leave secretly, after all, Canglong had a legitimate identity to visit, so he was nagging all the way.

"Why do you want to run? I'm really angry. The snow leopard was very uncomfortable, "It's a bit like being kicked out, are we really afraid of the Americans?" ”

Black Impermanence drank water, ate and didn't say anything, Vivien seemed a little irritable, lifted her sun hat covering half of her face with her hand, and said coldly: "You are talking nonsense, believe it or not, I invited you to eat popcorn?" ”

The snow leopard immediately shut up, because he saw Vivian move his hand, and it was obviously a miniature submachine gun inside, but after a few minutes, the snow leopard couldn't help it again, it seemed that he and Hei Wuchang had a commonality, that is, he couldn't stay idle in his mouth, but Hei Wuchang liked to eat to satisfy his mouth addiction, but Snow Leopard liked to talk very much.

So he found Tang Long: "Are you still adapting?" ”

Tang Long ignored him, just leaned against the window, looking at the scenery outside, for his indifference, the snow leopard was not discouraged, but energetic: "Don't you want to be a killer?" If your teacher doesn't teach you, how about I teach you? ”

When Tang Long heard this, his originally lazy spirit immediately fought: "Really? But aren't you a soldier? ”

"Go, although I am a soldier, I am also a special soldier, and I am the most awesome, definitely not worse than your teacher, and even he is inferior to me in some aspects." The snow leopard blew the cowhide without blushing and his heart was beating, and when Hei Wuchang heard his words, he stopped chewing and glared at him in disdain, and then ate his things again.

As for Vivian and Canglong, one was sleeping with a sun hat, and the other was squinting and didn't know what he was thinking, and seeing that no one spoke to despise him, the snow leopard was even more energetic: "Actually, he is not as good as me, otherwise how could he be afraid of the Americans, you see, I am not afraid of the Americans." ”

Tang Long was a little unconvinced, but he had seen the snow leopard fight, sometimes he really liked the tough guy style of the snow leopard, he really wanted to learn black impermanence, but he didn't have the body of black impermanence, and his body was also considered thick in front of ordinary people, right? But in front of the snow leopard, it is scum, the body of the snow leopard is thick in front of the special forces, but it is scum in front of the black impermanence.

"Can you really teach me?" Tang Long asked.

"Of course, but you have to worship me as a teacher first!" The snow leopard smiled "hehe", "You must know that there are many people in this world who want to worship me as a teacher, not to mention a reinforced battalion, at least a reinforced company!" ”

"Bragging!" Tang Long looked incredulous.

"Don't believe me?" The snow leopard was a little angry, "Do you know what is most important to survive here?" ”

"Water?" Tang Long thought for a while and said.

"It's not!" The snow leopard was stunned and vetoed directly, seeing that Tang Long was excited to get an answer, the snow leopard smiled and said, "It's to keep the water in the body!" ”

"Cut, isn't that water?" Tang Long looked disdainful.

"The external water is completely different from the inner water, the water I am talking about is the water in the body, and the external water you can't drink or can't drink, it's useless, right?" Snow leopard said.

"Kind of makes sense." Tang Long nodded.

"So, the most important thing to survive here is to keep your body hydrated and try to find as much water as possible." Snow Leopard said with a smile on his face.

"So how do you keep the water in your body from losing and find water?" Tang Long looked outside, it was a mess, except for the desert or the desert, although it was not like the kind of sand dunes in Africa, but there was basically not much difference, in such an environment, how could it be possible to find water? And it is not to keep the body water loss, after all, if you want to find water, you have to move, and if you move, you will lose the water in your body.

"Let's talk about how to keep the water in the body from draining." The snow leopard said and talked a lot, and Tang Long, who listened to it, was very excited, because he had never heard of these methods.

After the snow leopard rested for a while, Tang Long asked anxiously, "What else?" ”

"The human body is made up of three-quarters of water, and we need water to survive, especially in this desert environment, if your body does not adapt to this environment, and you do not bring enough water, under the sun, you don't have to walk ten kilometers, you will be dehydrated and shocked, and finally die in the desert." The snow leopard said lightly, "So it is especially important to know whether you are short of water." ”

"How do I know if I'm short of water?" Tang Long asked.

"Special forces like us, just by feeling, we know whether our body is short of water, as for a rookie like you, I guess you know to drink when you are thirsty, but drinking water like this is just a fee, especially in a special environment, but there is indeed a way to know how much water your body has lost." Snow leopard said.

"What's the solution?" Tang Long asked.

"When your body loses five liters of water, the pulse rate will be less than 100 beats per minute, the breathing rate will be twelve to twenty times per minute, and the body's response will be thirst, irritability, nausea, weakness, so you need to replenish water, but not too much, no more than 1.4 liters per hour, otherwise cerebral edema and pulmonary edema will occur, resulting in death." The snow leopard smiled, "So drinking too much water can be fatal, not drinking water can also be fatal, and many people get sleepy in the summer because of the lack of water in the body, although they don't feel thirsty." ”

But Tang Long felt a little infiltrating when he heard it: "So serious? ”

"Of course, when the body loses 10% of its water, it can cause dizziness, headaches, difficulty walking, and tingling in the limbs, so if you don't replenish water at this time, you are basically not far from death." The snow leopard is unequivocal, "manifested by a pulse beating of one hundred to one hundred and twenty beats per minute and twenty to thirty breaths per minute." ”

"And then?" Tang Long wrote it down attentively.

"Fifteen percent of the body is depleted with water, which can lead to dizziness, stinging in urine, swollen tongue, deafness, and numbness of the skin." Snow Leopard said, smirking grimly, "At this time, you are basically on the verge of death, and at this time, the pulse beats between one hundred and twenty and forty, and the respiratory rate varies from thirty to forty. ”

"What about the loss of more than 15 percent?" Tang Long asked.

"Huh." Snow Leopard smiled, "If no one saves you, you will basically go into shock, if it is in a desert environment, once shock is equal to death, of course, the premise is when you are alone, so water is the most important thing for a special soldier, so we need to train a good sense, to grasp their physical condition, at any time to determine what they need, like you students, if you students, it is estimated that you enter the environment of Iraq, and you are not familiar with life, it is estimated that you will not even be able to pass this first level!" ”

"Teacher Cang, is what he said true? Didn't you bluff me? Tang Long looked at Canglong, still a little skeptical, because he had never felt that water was so important.

But Canglong didn't answer, Vivian lifted the brim of his hat and said: "What he said is very right, you don't feel the importance of water, because you live in an environment where there is never a shortage of water, once you get to a water-scarce environment, you know how important water is, especially in Iraq, where there is a lot of oil, but there is not much water here." ”

Hearing this, Tang Long nodded: "Then how can we find a water source in this environment?" After all, there are so many Iraqis living here, aren't they? ”

"You're wrong, the people here can survive, it's not because they are always desperate to find water, just like the snow leopard said, adapting to the environment here, so that their water does not drain, is the best water source, do you know why Middle Easterners always dress so conservatively? In fact, there is a role, because the fibers of their clothes are specially made, just like the military uniforms of the U.S. military, which can stop the heat and cold, which can reduce the water loss of the body, of course, the people here are also adapted to the environment here, so their body water loss will be much slower than that of people in other regions. Vivien said, glancing sarcastically at the snow leopard, "He told you that it was right to keep the body from losing water, but he didn't tell you, nonsense is the easiest way to lose water from the body, because the salivary glands tend to secrete more water, and then swallow it into our stomach, and saliva is not completely water, when it enters the stomach, the stomach will digest it as food, just like drinking drinks will never quench your thirst, because the stomach digests drinks as food, and digestion needs the body's water to supply, It's the same as a car that needs gasoline to run. ”

After speaking, Vivian closed the brim of her hat and continued to sleep, while Tang Long looked at the snow leopard speechless, and the snow leopard looked embarrassed, and quickly explained: "Anyway, we don't lack water now, hehe." ”

"Do you know why your head keeps squinting and sleeping?" After Hei Wuchang put all the things on the table into his stomach, he asked.

Tang Long looked surprised, he felt that Hei Impermanence's stomach was a bottomless pit, and he didn't feel that it was enough to eat five people's meals, and this was just his snack, but surprise was surprise, he still shook his head about Hei Impermanence's problem, but he was very interested.

"When you become a killer, you will understand that sleep is a luxury, so it is a killer's instinct to sleep whenever you have time, and the head does not speak because he wants his body to adapt to the environment here as soon as possible, which requires subconscious psychological comfort, of course you can't reach this level." As he spoke, Hei Wuchang stood up and moved for a while, and then fell asleep upside down.

Tang Longzheng was speechless, and Hei Wuchang suddenly opened his eyes again and said to the snow leopard: "You like to talk so much, you are now in charge of standing guard." ”

As he spoke, he looked at Tang Long again: "Another point, in the enemy's territory, if there are no teammates standing guard, you have to open one eye and close one eye if you want to sleep, and as a killer, there are no teammates, so the killer must get used to resting and turning a blind eye, unless you can practice the sixth sense!" ”
