Hosted female soldiers, all become world-class special forces

Chapter 438 Comprehension 【Please order】

Sharks can smell blood and flesh at a concentration of 1ppm (one part per million) in water, and their sensitive sense of smell can smell the blood of injured people and marine animals several kilometers away.

What a terrible sense of smell!

Of course, in addition to the sense of smell, sharks also have a sixth sense - sense electricity, through which sharks can detect the weak electric field several feet around the object.They can also sense, through mechanoreception, the vibrations of fish or animals 6 feet away.

There is a special cell network system on the shark's head that can detect electric currents, called electroreceptors. Sharks use electroreceptors to hunt prey and swim freely in the water.

This is basically because sharks have two independent genes of neural crest cells in their electroreceptors.

And this neural crest cell is the embryonic cell that forms various tissues in the early stage of embryonic development.

Human neural crest cells play an important role in the formation of human facial bones and teeth.

This suggests that neural crest cells move from the shark's brain to various regions of its head, where they develop into electroreceptors.

This is probably the shark's tactile system.

In addition to smell and touch, sharks also have two special senses, one is the collateral nervous system, which is a row of nerve endings distributed on both sides of the body.He can make sharks perceive any activity in the water; another special sense is the ability to perceive the subtle electric charges emitted by other creatures, called the ampulla of Lulenz.

There are so many terrifying systems for catching prey, they are simply bugs!

What other prey could escape a shark's reach?
It is simply a terrible hunter in the ocean!
Zhuang Ming was completely familiar with all this, so he was not surprised at all. He was also surprised that there were sharks in this area.

Knowing the awesomeness of these sharks, Zhuang Ming is also very clear about their shortcomings.

When sharks swim, they mainly rely on the body, moving like a snake and moving forward with the scull-like swing of the tail fin. The stability and control mainly use the somewhat vertical dorsal fin and the horizontally adjusted pectoral fin.

So the shortcoming of sharks is clearly exposed, that is, many sharks cannot go backwards at all, so it is easy to get caught in obstacles like gillnets, and once caught, it is difficult to get out.

And sharks are slightly denser than water, which means they sink to the bottom of the ocean if they're not actively swimming.

As long as he can't swim without using his hands, the shark is completely dead.

So the shark's tail fin, dorsal fin, and pectoral fin are its weak points.

The sharks rushed towards Zhuang Ming at an undisguised speed.

These sharks could sense Zhuang Ming's existence because Zhuang Ming's body was baptized together to form a strange bioelectricity, and this bioelectricity was captured by these sharks.

The terrifying mouth opened in the water, and it swam towards this side quickly.

The sharp teeth can be seen from a distance.

Even in the sea, there is still a frightening cold glow.

And in the same way, Zhuang Ming did not leave, but surfaced, and quickly exchanged a nutritious meal from the system. At the same time, he increased his oxygen intake and recovered his physical strength. Adjust the speed to the best, calculate the time, dive into the water again, and take the initiative to attack the shark!

The leading instructor, Guishou, and the instructors stared at this scene in astonishment, unable to say a word at all.

Zhuang Ming never used two swords to kill a shark.

Zhuang Ming is like a swimming fish, extremely flexible.

Compared with the huge size of the shark, Zhuang Ming's figure has become an advantage!

Even though it felt like Zhuang Ming didn't use much force, Zhuang Ming's figure had already flown far away, like a big crucian carp, very fast and much more flexible than a shark.

I saw Zhuang Ming's figure suddenly soaring into the sky directly from the siege of several sharks, like a fish leaping over a dragon's gate.

The one next to it was obviously much stronger than the other sharks, and it was also much bigger. The shark suddenly shot up from the sea and directly bit Zhuang Ming.

The foul-smelling bloody mouth made people nauseous, Zhuang Ming's violent and powerful body seemed to pause in the air for an instant, and the Tang knife in his hand suddenly disappeared without warning.

"Ang~"

The roar from the big shark's throat is shocking.

But the sound also suddenly stopped.

The flat and pointed mouth of the shark suddenly exploded,
wow~~~
呲味~~~
Biao shot out incomparably gorgeous blood, the white shark meat and a small brain that was just cut in half.

As for the more in the middle, there are shark's internal organs and some black flesh.

A shark several meters long was split in half.

It's like half blooming, so beautiful.

He tapped the shark carcass lightly with his toes, and with a handsome and unrestrained somersault, he turned directly out of the shark's encirclement.

bang~
Because of Zhuang Ming's disappearance, those sharks had no time to dodge, and besides, they also had no chance to dodge.

They collided directly, making a huge noise.

It happened that four sharks collided with each other, and they were dizzy from the direct impact. For a while, they lost their balance and ran wildly in the sea.

Huge water splashes flew high above the sea level, and the swimming routes of these four sharks became crooked, like half-drunk drunks.

The shark in the air also fell directly into the sea, instantly dyeing the sea red.

And those shark companions opened their bloody mouths again in an instant, biting their dead companions.

"Whoa~"

Zhuang Ming fell into the water calmly, and the splash was almost negligible. Even in this state of jumping high, Zhuang Ming could still control his body, with a hint of ridicule on the corner of his mouth: "In the end It's just a group of creatures without intelligence, acting only by instinct."

kill!

kill!

kill!

Zhuang Ming forgot everything, only the constant killing, this shark school's sparring partner was much better.

There are so many, this kind of overlord in the sea makes Zhuang Ming feel like dancing on the tip of the knife of death.

Adrenaline rush!

Tang Dao cuts more and more smoothly in the sea water, reaching an extreme!
At this moment, Zhuang Ming seemed to clearly sense the texture of the sea water. Tang Dao slashed across, following the texture, more relaxed, faster in the water, and the knife became more fierce!
Why do people often change various stimuli in training?

The sparring partner also needs to be changed!

Because people are inherently bored, it is the normal state of human beings to like the new and dislike the old, just like behind every goddess there is a man who hates her.

Therefore, people need the stimulation of various new things and will become more excited.

like now!

Shark is Zhuang Ming's freshest partner!

And there was an endless stream of people rushing up one after another, fearless of death!

Where can I find this kind of partner?
Well, it's this kind of partner who wants to eat him!
