i have a small world

"Monkey, why are these sand tiger sharks still following us? We are already several nautical miles away from the group of adult sand tiger sharks. Those sand tiger sharks should not be able to find us. Monkey, what's going on?"

That's right, the two huge blue-black figures just now are actually the figure of the Sand Tiger Shark.

Regarding the appearance of the sand tiger shark, Leng Xin thought that he had already made enough preparations. Unexpectedly, after the sand tiger shark really appeared, Leng Xin discovered that he was not prepared at all in his heart.

Otherwise, Leng Xin would not have been frightened and stunned after the sudden appearance of the sand tiger shark, and had to rely on the monkey's reminder before he started running for his life.

However, because of this, Leng Xin wanted to find out why those sand tiger sharks appeared. In this case, Leng Xin could make some preparations in the future.

"Hey..., it must have been caused by the yellow hair that was torn into pieces by the ice blade of the young sand tiger shark when we jumped off the ship. The yellow hair was torn into pieces by the ice blade of the young sand tiger shark, .sz Therefore, he shed a lot of blood into the sea at that time.

This blood will not play any role for us, but, brother, don't forget that the shark's sense of smell is extremely powerful.Brother, among all sea creatures, sharks are the ones with the most sensitive sense of smell.Sharks are particularly sensitive to smells in seawater, especially bloody smells. The low-frequency vibrations or a small amount of bleeding from wounded fish can attract them from a distance. In this regard, the shark's sense of smell It can even surpass the sense of smell of land dogs.

According to the research of some relevant units, the dog's sense of smell is extremely sensitive.The olfactory sensitivity to acidic substances is tens of thousands of times higher than that of humans.

This is all because there are many folds of olfactory mucosa on the upper surface of the dog's nasal cavity, such as 150 square centimeters for German shepherds, but only 4 square centimeters for humans.There are about 2 million olfactory cells in the canine olfactory mucosa.40 times that of humans.

The nose of a healthy dog ​​is always moist, this is because the moist nose absorbs the suspended odor in the air and combines it with the sensory nipple, so the dog can smell the smell of a person 400-500 meters away, and can smell it in one place. Identify a stone that has only been held in the hands of a person for 2 seconds from a large pile of stones.Hoo..., hoo...! "

When it came to this, the monkey took a few breaths.Having said so much all at once, the monkey was a little out of breath when he was swimming at high speed to escape.

but.Soon, the monkey continued talking, and Leng Xin was listening attentively, and in the next escape.Monkey still has to rely on Leng Xin.Therefore, the monkey couldn't help but continue talking. "Brother, dogs can not only accurately smell the smell of adding a drop of blood to 5 liters of water, but also distinguish the kind of animal blood, and can also distinguish more than 10 different smells. The utilization of the dog's sense of smell is 100%. And this skill is crucial in its life.

Dogs mainly recognize their owners, routes, directions, prey and food based on olfactory information.According to the characteristics of dogs with a keen sense of smell, people often train dogs to use their superior sense of smell to compile drugs and solve crimes.Track suspects for thousands of miles, or hunt wild animals in the vast forest.

It can be seen from this comparison.The shark's sense of smell is so powerful in the ocean. Sharks can easily smell 1pp in the water, that is, the smell of blood and flesh at a concentration of one part per million.

Some scientists have found that even if only 1 gram of amino acid is dissolved in 1 tons of seawater, sharks can sense the smell and gather together.Just like a female shark is about to give birth-after giving birth, even after roaming thousands of miles in the sea, she can swim upstream along the scent and return to her birthplace to live.

Some people have measured the shark's sense of smell: the total area of ​​the olfactory membrane of a 1-meter-long shark can reach 4842 square centimeters, so the shark's sense of smell is very sensitive, and it can smell blood-fishy smell a few kilometers away. Once an animal in the sea is injured, it is often killed by a shark attack.

For example, the 5-7 meter long man-eating shark, with its sensitive sense of smell, can smell the blood of injured people and marine animals several kilometers away - the fishy smell.

Sharks' keenest sense of smell is their sense of smell. They can smell extremely fine substances such as blood from miles away, and trace the source.

They also have a sixth sense - electricity, by which sharks can detect weak electric fields a few feet around objects.They can also sense, through mechanoreception, the vibrations of fish or animals 6 feet away.

Sharks have an extremely keen sense of smell and can easily sniff out odors that they fear or dislike.

Sharks can also smell the smell of L-hydroxyalanine, a human secretion with a content of 800/[-] billion in seawater.

It is said that there was once an expert shark fisherman. In the subsequent shark fishing, the sharks always missed his hook, but other fishermen in the same fishery caught more sharks instead.

Why are sharks afraid of this expert shark fisherman?According to the research of ichthyologists, the shark fishing expert had suffered from skin diseases, so the fingerprints left on the fishing rod contained more L-hydroxyalanine.When the shark smells this kind of smell, it will naturally avoid him, and this is the reason why the shark does not take the bait.

As for why the shark’s sense of smell is so sensitive, it is because there are two forks (nasal sacs) in the front of the shark’s brain extending to the nostrils on both sides of the snout, and the fork is very sensitive, and it will turn when it smells. The shark’s nostril is divided into two parts, the front part is the water inlet hole and the rear part is the water outlet hole. Therefore, the shark’s sense of smell is very keen, and it can distinguish the smell of 100 billion parts in the water. .

Brother, the sense of smell of the sharks on the earth is so sensitive. In the secret world of martial arts, the sand tiger sharks that have evolved into savage beasts, their sense of smell is absolutely better than those of ordinary sharks on the earth. Even stronger.

And now we are only a few nautical miles away from these sand tiger sharks. At such a short distance, those sand tiger sharks can definitely smell the blood of the yellow-haired blood-the fishy smell.

Besides, when the juvenile sand tiger shark launched an ice blade attack just now, although all of us jumped into the sea and escaped in time.However, there were still a few people who were bleeding from sassafras wounds from the ice blades fired by juvenile sand tiger sharks.

We've been swimming for our lives just now.There is no time to bandage the wound, so, it can be said that we have actually been leaving the trail of those sand tiger sharks just now.

Boss, the person who was directly torn in half by two Sand Tiger Sharks just now was one of the people who was injured by the juvenile Sand Tiger Shark Ice Blade Sassafras.

Boss, now we should do our best.Try to escape a relatively safe distance before the Sand Tiger Shark devours those injured by the ice blade, otherwise... hey...! "

A very deep exclamation came from the monkey's mouth.Now the monkey has a feeling of shooting himself in the foot with a stone, but the situation is already like this, and the monkey has nothing to do.Only to escape with all my strength.

After the monkey made this deep exclamation.He didn't continue, but Leng Xin was very clear about the unfinished meaning in the monkey's words.

That is, if they couldn't escape a safe distance before the sand tiger shark devoured those who were injured by the ice blade, the result would be that Leng Xin himself would be swallowed by the sand tiger shark.

Thinking that he was about to be swallowed by a sand tiger shark, Leng Xin couldn't care about other things.He buried his head and began to swim forward with all his strength.

As for now, we need to keep a certain distance from Xu Chang and Xu Jie.How could Leng Xin care about this now.If he can't escape a safe distance before those adult sand tiger sharks swallow those wounded by the ice blade sassafras, then everything is over, and keep the distance between Xu Chang and Xu Jie, and what else? What's the use.

………………………………………………………………………………………….
"Hoo...! Hoo...! Hoo...!...." Rapid breaths sounded from Xu Chang's mouth. Just now Xu Chang swam with all his strength for half an hour, so now Xu Chang has consumed a lot physical strength.

If Xu Chang hadn't been helped by the true energy in Xu Jie's body, he would have been so tired that he couldn't move.

"Huh...! Huh...! It's really tiring, Xiaojie, we should have swam nearly two nautical miles in the past half an hour!" Xu Chang was already tired from swimming, so he planned to slow down first.

When you are in such a dangerous situation, the most important thing is to maintain a certain amount of physical strength in your body. Don’t use up all your physical strength in order to avoid any dangerous things from happening. At that time, you will have the opportunity to react.

And if you don't spare some physical strength, then when something unexpected happens, you will have to wait for death.

"Well, brother, we were swimming at high speed just now, so we have indeed swam about two kilometers now, and our fishing boat has been fishing at a distance of [-] nautical miles from the shore (the fish in the Wulin Mijing Ocean The resources are too rich, so even if it is such a close sea, you can catch enough fish!), just half an hour of your swimming distance, plus Leng Xin and his fishing boat took us another distance, I think now We are only about fifteen nautical miles from the shore.

Brother, this time we will definitely be able to return to the shore safely. "

"Huh...! Huh...! That's good, that's good, there are only fifteen nautical miles away, if we work harder, we can go home for dinner tonight. When I think about going home for dinner, my body My strength has returned. Xiaojie, hurry up, I'm going to set off."

There was only fifteen nautical miles left, this news gave Xu Chang a surge of strength for no reason, and he was ready to set off again, trying to get back home as soon as possible.

Although this is near the sea, the danger is much smaller than that of the deep sea or the far sea, but the development of things is often changing rapidly, and the creatures in the sea are also very complicated. God knows what dangerous things will be hidden in the sea, so , Xuchang will continue to work hard to swim forward.

The sooner they landed, the two brothers would be out of danger earlier.

"Brother, don't worry, I will hurry up." After Xu Jie finished speaking, he grabbed Xu Chang again. The distance of fifteen nautical miles made Xu Jie's hope of surviving grow stronger and stronger.

"That's good, Xiaojie, let's go home!"

"Well, big brother, let's go back..., hey, what's that?" Just as Xu Jie was talking to Xu Chang with joy, he suddenly noticed something unusual happened not far behind him.

"Hmm...? What's the matter, Xiaojie? What happened?" Xu Jie's anomaly was also felt by Xu Chang very quickly.

"Brother, wait, let me take a closer look." Xu Jie found that the abnormal situation was still a certain distance from them.Therefore, Xu Jie couldn't see clearly at once.

"Well, Xiaojie, take your time, anyway, we are only fifteen nautical miles away from the shore, take your time, don't force yourself."

Xu Chang comforted Xu Jie.In Xu Jie's answer just now, Xu Chang felt a trace of Xu Jie's uneasiness, so.Xu Chang would comfort Xu Jie like this.The more dangerous and urgent it is, the more you need to keep calm.

In the real world, you should keep calm all the time.otherwise.There is absolutely no danger to you.

In an emergency, tragedies caused by not keeping calm and suddenly becoming panicked are very common in modern society.

The most famous are those 'female-killers', also known as 'female drivers'.

In modern society, the three words 'female driver' are no longer good pronouns, they represent danger.

This is all because the female driver encountered an emergency while driving.Often loses composure and becomes panicked.Thus leading to the tragedy.

Now there are countless tragedies caused by the "female driver".

For example, on May 2013, 05, there was a tragedy on Chengbei Road in the whole island city because a female driver panicked and mistakenly took the accelerator as the brake, which caused a tragedy.

On that day, two migrant workers were sitting on the side of the road and were talking and laughing a second ago. They never dreamed that bad luck would come the next second.

At noon on May 5th, in order to hide from a motorcycle, a Baolai car accidentally stepped on the brakes and turned the accelerator, and hit two migrant workers on the side of the road. One was knocked into the air, and the other was pushed into a tree On the spot, the two died on the spot.

The front of the Polaris that caused the accident was completely deformed. There was a motorcycle lying on the ground next to the car. A poplar tree on the side of the road had a piece of skin knocked off, and there was blood all around.

"Both were hit hard. One was pushed against a tree, and the other was knocked seven or eight meters away." Speaking of the accident just now, an old lady kept shivering.

"At that time, I heard two muffled noises, and when I looked again, the two people were already bloody!"

Ma xx works nearby. He said that the female driver who caused the accident looked to be in her 40s, her face was covered with blood, and she couldn't stand when she got off the car. .”

...............................................................................................................

On May 2012, 4, at around 7:5 p.m., Xu xx, who was pregnant for [-] months and his [-]-year-old daughter, was hit by a speeding truck while chatting with two villagers on the river dam beside the village. , the unborn baby boy died.

Two villagers were also injured.Afterwards, according to the investigation by the traffic police department, the perpetrator was a novice female driver Li Moumou, who had only held her driver's license for 20 days. Because she panicked for a while when meeting with the opposite vehicle, she mistakenly used the gas pedal as the brake and turned the car on the side of the road. Several of the crowd were injured, which caused this tragedy.

In this car accident, 68-year-old Zhang xx suffered a comminuted fracture of his left leg; 46-year-old Du xx suffered a hip fracture, his head was hit hard, and his body was also swollen; Xu xx’s 5-year-old daughter suffered a brain injury. After being cured, there may be sequelae such as stroke and bad temper. After being knocked out, the skin on the left side of the face was wiped off, and the whole face was completely unrecognizable.

Among the four injured, the most seriously injured was Xu xx's wife, Fan xx.Due to the car accident, Fan xx's whole body was fractured, and his liver, spleen, and kidneys were hemorrhaging.

……… Wait, wait, there are countless tragedies caused by the female driver panicking and mistaking the accelerator for the brake.

This is a tragedy caused by panic when encountering danger, so what is the result of keeping calm when facing danger?

There is an example (hey, I saw it with my own eyes!), which can illustrate how important it is to keep calm in times of danger.

The incident happened around 11:40 in the middle of the night on November 4 last year. At that time, a fire broke out in a business room along the street on the second floor of Building 2.The fire department received a call from the masses for help, and a fire broke out in a business room along the street on the 97nd floor of Building 4, xxxxxx Community, No. 2, XX Road, Chengnan City, urban area. At this time, a family of four living in the house was still trapped on the third floor. The situation at the time was quite critical.

After receiving the alarm, 7 fire trucks and more than 30 officers and soldiers went to the scene of the fire for rescue.By the time the firefighters arrived, the fire had already reached the third floor, and the scene was full of flames. Flames kept gushing out from the windows on the second and third floors. The whole house was billowing with smoke. The store is in the decoration business, the second floor is a warehouse, and the owner's family of four lives on the third floor.

Fortunately, before the firefighters arrived, the head of the household managed to get out of danger through self-rescue.While fighting the fire, the fire officers and soldiers used ladders to search the rooms on the fourth and fifth floors, and evacuated more than 10 residents upstairs and nearby residents.After nearly half an hour of fighting, the fire was finally extinguished.
