Facing the fratricidal scene of the sand tiger shark group's 'people die for money, birds die for food!', Leng Xin, the monkeys, Xu Chang, Xu Jie and his party were dumbfounded, especially when those sand tiger sharks were fighting, the countless real qi bombs and real qi blades were inspired, which made them even dumbfounded, and even they forgot that now for them, the first thing is to escape.

More than a dozen sand tiger sharks were lured by the aura contained in the qi replenishing pills, and they got carried away with each other on the sea. It may seem like this is incredible, but it's actually due to the natural genetics of the sand tiger shark.

The sand tiger shark embryos kill each other in the womb, and eventually the largest embryo will devour the other embryos, leaving only one embryo of the same paternal line. Shark embryos from different fathers compete fiercely, and eventually the healthy and strong embryos will kill the other embryos to ensure "eugenics".

In a recent article in BiologyLetters, a journal of the Royal Society of England, researchers analysed shark embryos found in sand tiger sharks (Carcharias) and looked at the different stages of their gestation, finding that the later in pregnancy, the more likely it is that there is only one remaining shark embryo (the largest embryo eats the other siblings).

The researchers learned the reason: it was a form of paternal struggle in the womb, in which babies of different fathers competed with each other for birth.

The researchers analyzed the different stages of gestation in the embryonic gestation of the tiger shark (Carchariastaurus) shark and found that the more advanced the pregnancy. The more likely the remaining shark embryos belong to the same father.

This discovery suggests that cannibalism within embryos is actually a competitive strategy, with males trying to ensure the dominance of their paternal line.

Study co-author Demian Chapman, a marine biologist at the State University of New York at Stony Brook, said: "In some species, paternal struggle persists after the female mated with the male. ”

Fully developed tiger sharks are generally up to 2.5 meters long. Shark mothers tend to give birth to 2 baby sharks, each about 1 meter long. Since the 80s of the 20th century, detailed autopsies of tiger sharks have revealed that there are other baby embryos in the stomach of shark fetuses, and researchers have learned that shark fetuses can kill each other in the womb, lasting from about 5 months to up to 1 year gestation.

A researcher allegedly got bitten by a shark fetus when he put his hand into the mother's womb during the dissection.

"When 12 littermates grow together in their mother's womb," Chapman says. One of the sharks will devour the other siblings. This strategy allows tiger sharks to be larger at birth than other shark species, making them safer than other predators. ”

But scientists don't know why sharks cannibalize, and one possibility is that females mate with multiple male mates. Cannibalism puts one father's genes in the driver's seat.

To find out, Chapman and his colleagues studied genetic samples from 15 pregnant female sharks that died off the coast of South Africa.

Of the 15 females, 10 had two fetuses and 5 were in early pregnancy. The remaining sharks carry 5 to 7 fetuses in their wombs. The team used DNA analysis to determine the paternal line.

"DNA tests are commonly used to determine how many fathers these fetuses have. Chapman said.

Those with 5 to 7 fetuses have at least two fathers. And those with only two fetuses in total usually have only one father. This suggests that an embryo – which is likely to grow first to become the largest – tends to devour siblings from other fathers. "To put it simply, the father who loses the competition provides food for the offspring of the winning side. ”

As for which father won in such a birth competition, it is still a mystery, James of the University of North Florida, a marine biologist at the University of North Florida? James J. Gelsleichter put it this way.

"Male and female culling is very similar to an evolutionary arms race, where male and female individuals compete against each other. Jells Reicher said. It is also possible that the embryo born from the first male father will grow first and devour the other siblings in the embryo.

This strategy can also help females choose better mates. Shark mating involves ferocious bites, so cannibalism in the womb allows the female to avoid resistance and mating "selection difficulties," but also to ensure that she produces offspring for better males, says Gilles Rechert.

Therefore. It is clear that the sand tiger shark is definitely the coldest. The most evil kind of shark, and because of this, the sand tiger shark only sees interests in front of it, as long as it is about its own interests.

These sand tiger sharks can completely ignore a qiē, even if the sharks around it are its own kind, but as long as these same kind hinder the interests of the sand tiger shark, this sand tiger shark will also go on a killing spree.

It doesn't matter if the sharks around it are its own kind, or even its brothers and sisters, the sand tiger shark has only its own interests in its eyes and bones.

Qi Replenishing Pill is used by martial artists to replenish the aura consumed by the body, of course, it can also be used as an elixir used by martial artists in cultivation, therefore, the name of the pill of Qi Replenishing Pill looks very inconspicuous, in fact, the Qi Replenishing Pill is very important for martial artists, and therefore, the price of Qi Replenishing Pill in the jade pagoda is not cheap, correspondingly, all martial artists attach great importance to these things as Qi Replenishing Pills.

The effect of the Qi Replenishing Pill on martial artists is so strong, and it is also true for those brute beasts.

For warriors, brute beasts are only different in appearance and genes, but brute beasts are the same as warriors, and the heart of pursuing the growth of their own strength is also very strong, and even, compared to martial artists, brute beasts are more urgent in the pursuit of their own strength, and more naked-naked.

Because, all brute beasts live in the wild. The dangers of the wild are well known, so these brutes want to live. They have to do their best to improve their own strength, so that they can survive the cruel competition of nature.

The more powerful the brute beast, the more qualified it is to survive, and the more qualified it is to treat other brute beasts as their own food.

It is precisely because of these reasons that once an elixir appears in front of the brute beasts, these brute beasts will turn their attention to the elixir as soon as possible. The innate spirituality of the brute beasts will clearly tell them that these elixirs have a great effect on the improvement of their own strength.

What will it be like at this time? I believe that everyone can imagine it clearly.

Of course, if the brute beasts that found the elixir were of the same kind, like wolves and horses. Savage cattle or something, etc. Because these barbarian beast groups have the existence of a leader, and they are not so cold-blooded in their hearts, they regard their compatriots as disregarded, so even if these barbarian beast groups see an elixir like the Qi Replenishing Pill appear in front of them, these barbarian beast groups will not have any cannibalistic actions.

Even if there was some cannibalistic action, however, as soon as their leader came out. These cannibalistic actions will disappear one hundred percent, so. If the brute beast clan that Leng Xin and they encountered was one of these brute beast clans, then their plan would be 100% in vain.

Fortunately, Leng Xin and the others encountered the most brutal, cold-blooded, and ruthless sand tiger shark group.

These sand tiger sharks are precisely because of their brutality, cold-bloodedness, and ruthlessness carved into their bones, so these sand tiger shark groups do not have any leaders, so when faced with the temptation of qi replenishing pills, this group of sand tiger shark groups immediately killed each other.

For the sake of their own strength, what kind, what brothers and sisters, these sand tiger sharks do not pay attention.

Even if it is the scene of the sand tiger sharks killing each other on the earth, people will be surprised when they see it, and they can't help but stop and want to watch this fight, the current sand tiger shark is the sand tiger shark in the secret realm of martial arts.

These sand tiger sharks are not only far more than the sand tiger sharks on the earth in terms of volume, but also the sand tiger sharks in the martial arts secret realm are brute beasts, and they will use some real air bombs or real air waves when they fight, so in terms of the scene, it is definitely more magnificent and more eye-catching than the scenes of the sand tiger sharks killing each other on the earth, so now Leng Xin, the monkey, and the two brothers Xu Chang and Xu Jie are attracted by the scene of the sand tiger sharks killing each other and forget to escape, which is a forgivable thing.

Anyone, after seeing such a grand scene, can't help but stop in their hearts and want to watch this grand scene.

Of course, if Leng Xin, Monkey, Xu Chang and Xu Jie really watched the scene of the sand tiger shark killing each other, then their result would be very clear, and they were killed by the sand tiger shark.

Fortunately, fate didn't want Leng Xin, the monkey and the two brothers Xu Chang and Xu Jie to die like this, and a roar that shook the sky saved them.

"Woo......! Woo............!......。 "......! ......!......!......。 "Poof......!poof......!poof......!......。 Such a voice sounded above the sea.

The first sound is actually the sound of the Sand Tiger Shark casting its True Qi Blade or True Qi Bullet, the middle sound is the sound of these True Qi Blades or True Qi Bombs being stimulated by the Sand Tiger Shark and flying at high speed in the air, and the last sound is the sound of those True Qi Blades or True Qi Bullets inspired by the Sand Tiger Shark hitting other Sand Tiger Sharks.

The size of the sand tiger shark is very large, a full twenty-five meters long and four or five meters wide, so it can be imagined that the true qi content in the body of the sand tiger shark is also very large, so the number of true qi blades and true qi bullets inspired by these sand tiger sharks is really considerable.

The number of true qi blades or true qi bullets inspired by a sand tiger shark is about fifty or fifty rounds, and there are more than a dozen sand tiger sharks in this narrow sea area, and their attacks are group attack waves, so what the scene is like is definitely imaginable.

In this sea area, full of True Qi Bombs or True Qi Blades, these huge sand tiger sharks will of course be hit.

In the face of so many group attacks, these sand tiger sharks were able to avoid some of them, but other waves of attack still hit them.

In an instant, countless True Qi Blades and True Qi Bullets hit these Sand Tiger Sharks.

"Bang ......! Bang ......! Bang ......! Bang ......!......。 "The surface of the sea is full of the sound of True Qi Blades or True Qi Bullets hitting the Sand Tiger Shark, of course. Because the sand tiger shark has the protection of the talisman qi, many true qi blades and true qi bombs are blocked by the talisman qi on the sand tiger shark.

However, the strength of the protective qi on the sand tiger shark is limited. These talisman qi can withstand ten, twenty, or even thirty attacks of true qi blades and true qi bullets, but forty, fifty, or even more attacks of true qi blades and true qi bullets. The protective qi is completely irresistible.

Besides, the number of True Qi Blades and True Qi Bullets that these Sand Tiger Sharks are facing now is compared to forty. There are a lot of fifty paths coming, so what will happen to this group of sand tiger sharks is something that can be imagined.

The Protective Qi on the Sand Tiger Shark's body only fended off the attacks of those True Qi Blades and True Qi Bullets for less than five seconds. And then. I heard a very crisp sound, like glass being broken.

"Click......! click......click......!......。 "Squeak......! Squeak......! Squeak......! Squeak......!......。 "Bangla...... Bangla............!......。 The sound resounded throughout the sea in less than a second, and then, the protective qi on the sand tiger shark's body broke.

Those True Qi Blades and True Qi Bullets that had just been activated by the Sand Tiger Shark hit the body of the Sand Tiger Shark that was close at hand, and in an instant, a cloud of blood mist appeared on the surface of the sea.

A clump was fifty meters wide. More than two meters high blood mist appeared on the surface of the sea, and then followed by an earth-shattering roar: "Roar...... Roar! Roar...... Roar......!......。 "In this earth-shattering roar. The pain of the sand tiger shark can be heard very clearly.

Also, being hit by dozens of True Qi Blades and True Qi Bullets will of course hurt a lot.

Fortunately, the size of the sand tiger shark is large enough, and now the talisman qi in the sand tiger shark's body has recovered again (after the talisman qi is broken, it takes a few seconds to recover immediately), so these True Qi Blades and True Qi Bullets have not been able to seriously injure them.

However, even if this is the case, it is enough for these sand tiger sharks to drink a pot, of course, it is precisely because of this that Leng Xin, Monkey, Xu Chang, and Xu Jie The two brothers were finally able to come back to their senses.

The earth-shattering roar of the sand tiger shark because of its injury reached the fishing boat, waking up Leng Xin and his party who were stunned by the scene of the sand tiger shark killing each other.

Looking at the bloody scene in front of them, and those sand tiger sharks are still killing each other, and the sea surface has been dyed a blood red, Leng Xin, Monkey and Xu Chang, Xu Jie The two brothers couldn't help but shudder, they really felt scared in their hearts.

Watching these huge beasts fight up close, the sense of oppression, the sense of shock in the soul is really unforgettable.

Of course, at this time, Leng Xin, Monkey, Xu Chang, and Xu Jie quickly realized that now was their best chance to escape, and in addition, they were only more than fifty meters away from the place where the sand tiger shark was fighting, and such a distance was too dangerous.

Leng Xin and the monkey glanced at each other, and then Leng Xin shouted loudly without hesitation: "Everyone pick up the oars, do your best, row with all your might, we have to escape here before those sand tiger sharks kill each other." If you don't want to bury the belly of the sand tiger shark, then from now on you will take out the strength of your milk and row with all your might!"

Leng Xin ordered loudly to the other people on the fishing boat, and now the sand tiger shark was also making a heaven-shattering sound, so Leng Xin could speak loudly without any scruples.

After saying these words, Leng Xin turned around without hesitation and picked up the oars and began rowing, and began to row.

Now is definitely their best chance to escape, Leng Xin doesn't want to waste a second, they want to take advantage of this best opportunity, do their best, and leave here as much as possible.

With Leng Xin's loud shout and Leng Xin's leading role, the other people on the fishing boat also began to pick up the oars and row the boat with all their might.

In order to concentrate his forces and make the fishing boat escape from danger faster, Leng Xin had already concentrated the people on the other fishing boat on this fishing boat, and as for the other fishing boat, Leng Xin decided to give up.

Anyway, for Leng Xin, a fishing boat is not in his eyes at all, and now for him, escape is the most important thing, as long as he can go ashore safely, when the time comes, he will be able to get any fishing boat.

With Leng Xin's full rowing, the fishing boat instantly rowed towards the distance at a very fast speed, and soon, the sand tiger shark group was left behind by Leng Xin and them.

"Whew....... Seeing that the sand tiger sharks were left behind, the two brothers Xu Chang and Xu Jie, who were in the stern of the boat, couldn't help but breathe a sigh of relief.

"Big brother, now we are finally safe, this time we were able to get out safely, speaking of which, we really rely on monkeys. Ay...... , it's really unexpected!" Xu Jie let out a sigh from his mouth.

"Hehe, Xiaojie, didn't I tell you a long time ago, you have to be forgiving and forgiving, now you know the meaning of this sentence!"

"Well, big brother, I understand, in the future, I will firmly remember the phrase 'forgive others and forgive others', I will act in the future, I will not drill the horns again, big brother ......!"

"......Whoa!" At this moment, a loud voice interrupted Xu Jie's speech, and then, a black shadow rose into the air, instantly enveloping Xu Jie and the two brothers Xuchang.

As soon as they saw this black shadow rising into the sky, the two brothers Xu Chang and Xu Jie exclaimed loudly: "Sand Tiger Shark ......!"
