Desert Island Survival Belt System

358 Chapter 387, Horseshoe crab
seaside!

The waves never stop rolling, rushing to the immaculate silver-white sandy beach again and again, and the clear blue water is covered with sand and gravel.

Some slender fish are chasing the waves on the beach. These are some small sardines.

There are no big predators in the waters near the sea, and these small sardines have to swim in the sea in order to survive.

sea!

The most mysterious place in the world with the most species and the largest area!

The ocean is the origin of life on earth. As early as billions of years ago, the original appearance of the earth was nothing but a mountain and a sea.

And the first life on earth originated from the ocean!
According to scientific explanation, the emergence of life is due to the refraction of sunlight through the atmosphere, which weakens the radiation, and the light in the sea breeds many single-celled microorganisms.

It was these microorganisms that were the first life on earth, and then began to evolve over hundreds of millions of years, some evolved into crustaceans, and others evolved into fish.

"What's that?" Lin Qingxue stretched out her hand to cover her forehead, pointing at the creature moving close to the bottom of the shallow sea.

From a distance, this thing looks like a turtle shell.

"It's horseshoe crab!" Qin Fengyi nodded, "That's right, it's a creature that appeared earlier than dinosaurs, horseshoe crab!"

"Nuuuuuuuuuu?" Lin Qingxue's expression was tangled, "What kind of creature is called such a name, because it tastes too salty, so it makes you panic?"

Qin Fengyi turned his head and stared at the serious Lin Qingxue, feeling a deep sense of powerlessness.

"Sometimes it's really tiring to communicate with you!" Qin Fengyi shook his head helplessly.

Limulus horseshoe crabs are really awesome. They have lived for more than one billion years and have not become extinct. With the advancement of humanities, it has been found that the blood in their bodies has a great role in medicinal value.

In some medical departments, it is not uncommon to see hundreds of horseshoe crabs being forced to draw 30% of their blood, because their blood is currently the only thing that can test human health.

"Hmph!" Lin Qingxue snorted coldly, and rolled her eyes fiercely, "What's the big deal, isn't it that you know more about animals!"

"Uh...it's okay..." Qin Fengyi nodded modestly.

"You self-righteous idiot!" For some reason, no matter how Lin Qingxue looked at Qin Fengyi during this time, she found it displeasing to the eye, not pleasing to the eye anyway.

"Dare to scold me!" Qin Fengyi turned around viciously, with a fierce look on his face, "At least half an hour tonight!"

I go……

Lin Qingxue, who was frowning, almost spat out a mouthful of blood, her little face turned pale, "Brother, I was wrong..."

"Begging for mercy now? It's too late!"

Qin Fengyi has been holding back for several days, facing the two charming beauties all day long, he can only look but not fuck, it is too tormented.

Now that I'm home, I must put it to good use.

"Mr. Han, please share the pain, help me!" Lin Qingxue knew her fate long ago. After going out for several days, Qin Fengyi was really bored. If there was a chance to torment Lin Qingxue, he would naturally not let her go.

"Hehe..." Han Xuening smiled bitterly, "There is nothing I can do to help..."

The flat creature in the sea couldn't escape the killer after all. The guy with the scar face was famously stupid and bold, and he usually ran into whatever he encountered.

Even if this guy sees a branch blocking the way, he will stop and compete with the branch.

"Crack...crack..."

Scarface held a similar flat thing in his mouth, and then put it on the beach, stretched out his little furry paws, and pressed the creature firmly.

"What is this, 彁..." Lin Qingxue knew that she was wrong, "It looks so strange... It looks like an alien creature."

"Limulus is also called horseshoe crab. It is said that its body is highly poisonous, but I have seen videos of crooked nuts being roasted and eaten many times." Qin Fengyi has watched many videos. These videos are not only the ones from island countries, but also many abroad.

In the video, many people have eaten horseshoe crabs, and the taste is pretty good.

Horseshoe crabs are protected animals, and they are not allowed to be caught in the same city, but on a deserted island where skeletons are rampant, the effect of the law is very weak.

"Horseshoe crab..." Lin Qingxue stared blankly at the flat creature, and really couldn't understand how it was related to crabs.

"Is this thing really poisonous?" It was also the first time Han Xuening saw this kind of creature, and it seemed that its shell was quite hard.

"Woo~!" Scarface was gnawing on the shell of the horseshoe crab, but this guy's attack power was too low to hurt the horseshoe crab at all. Instead, the flat guy was moving towards the sea.

"Whether it's poisonous or not, the blood of this creature is blue, and it should contain copper. That's not good for the kidneys." Qin Fengyi grabbed the honey badger who was still chasing the horseshoe crab.

Horseshoe crabs have made great contributions to human beings. They have survived on the earth for more than 4 million years. Now, because of the development of human medicine, they have discovered the value of the blue blood in this thing.

The blood of horseshoe crabs contains copper ions and turns blue. The "lysate reagent" extracted from this blue blood can accurately and quickly detect whether the internal tissues of the human body are infected by bacteria.

"Woooo..."

Once Honey Badger got angry, no one could hold it back. Qin Fengyi was holding this little thing weighing more than ten kilograms, its body was suspended in the air and it was still struggling.

I want to do it!

Big beast, let me go!
"Hoohoo~!"

In terms of obedience, Yayale is the best. It was the first to understand the owner's mind, held the horseshoe crab in its mouth, and finally released the prehistoric creature into the sea.

"The blue blood contains copper?" Lin Qingxue was whispering softly, and then she looked at Qin Fengyi in disbelief.

Noticing Lin Qingxue's strange eyes, Qin Fengyi twitched his mouth helplessly, "Why are you looking at me like this, are you interested in my cucumber?"

"Let me tell you, cucumbers are very powerful, but they can reach the stomach in one step!"

Qin Fengyi was talking yellow accent, but Lin Qingxue didn't listen to a single word. She had been with this animal for a long time, but she could completely filter out those words.

"I'll go, Qin Fengyi, you're such a scumbag." Lin Qingxue opened her eyes wide in shock, "I know that blue blood contains copper."

"I also saw it on TV." Qin Fengyi touched his nose, "Although I am a scumbag, I also have brains."

"Qin Fengyi's sentence contains copper, which is not good for the kidneys...it's really powerful." Han Xuening kept printing this sentence in her mind, and when she thought about it, she found it super funny, and it hit the point of laughter completely.

"His kidney..." Lin Qingxue had a bitter face, worrying about her own fate tonight, she murmured sadly, "His kidney is definitely made of alloy steel..."

The blood of horseshoe crabs contains copper ions and turns blue. The "lysate reagent" extracted from this blue blood can accurately and quickly detect whether the internal tissues of the human body are infected by bacteria.
