Seaside!

The waves never stop rolling, and again and again they crash onto the immaculate white sand, and the clear blue water rolls up with sand.

Some slender little fish chase the waves by the sea, and these are some small sardines.

There are no large predators in the sea near the sea, and these little sardines have to swim around the sea in order to survive.

Ocean!

The most mysterious, most species, and largest area in the world!

The ocean is the origin of life on Earth, and billions of years ago, the Earth was nothing more than a mountain and a sea.

And the first life on Earth came from the ocean!

Science explains that life occurs because the sunlight is refracted through the atmosphere, which weakens the radiation, and the light breeds many single-celled microorganisms in the sea.

It was these microorganisms that first life on Earth began to evolve over a period of hundreds of millions of years, some into crustaceans, others 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 a horseshoe crab!" Qin Fengyi nodded, "That's right, it's a creature that appeared earlier than the dinosaurs, horseshoe crabs!"

"What?" Lin Qingxue's expression was entangled, "What kind of creature is called such a name, because it tastes too salty and panics?"

Qin Fengyi turned his head and was looking at Lin Qingxue, who had a serious face, and suddenly felt a deep sense of powerlessness.

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

The horseshoe crab is indeed very awesome, it has lived for more than a billion years without extinction, and with the progress of humanities, it has been found that the blood in its body has a great role in medicinal value.

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

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

"Uh...... It's okay......" Qin Fengyi nodded very modestly.

"Self-righteous idiot!" For some reason, no matter how Lin Qingxue looked at Qin Fengyi during this time, he felt unpleasant, both horizontal and vertical.

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

I'll go......

Lin Qingxue, who was frowning, almost spurted out a mouthful of reverse blood, and her little face suddenly turned pale, "Big brother, I was wrong......

"It's too late to beg for mercy!"

Qin Fengyi has been holding back for several days, facing the two delicate beauties all day long, he can only watch but can't snap, it's too tormenting.

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

"Teacher Han, please share the damage and save your life!" Lin Qingxue already knew his fate, after going out for a few days, Qin Fengyi's animal was indeed stuffy, and if he had the opportunity to toss Lin Qingxue, he would naturally not let her go.

"Hehe......" Han Xue smiled bitterly, "I can't help ......"

The flat creature in the sea didn't escape the killer after all, and Scarface was notoriously stupid and bold, and usually encountered anything to scare him.

Even if he sees a branch in the way, he will stop and fight with the branch.

"Smack...... Snap ......"

Scarface had something like a flat in his mouth, then placed it on the sand, stretched out his little furry paws, and pressed the creature to death.

"What is this, ......" Lin Qingxue knew that she was not right, "it looks so strange...... It's like an alien creature. ”

"Horseshoe crabs, also known as horseshoe crabs, are said to be highly poisonous in their bodies, but I have seen crooked nuts roasted and eaten many times. "Qin Fengyi has watched a lot of videos, these videos are not only the kind of island countries, but also many foreign ones.

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

Horseshoe crabs are protected animals and are not allowed to be caught in the same city, but on a desert island infested with skeletons, the role of the law pales in comparison.

"Horseshoe crab ......" Lin Qingxue looked at the flat creature blankly, and really couldn't understand how this thing had anything to do with crabs.

"Is this thing really poisonous?" Han Xuening also saw this creature for the first time, 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, and this flat guy was moving towards the sea instead.

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

The horseshoe crab has made a great contribution to mankind, having survived on the earth for more than 400 million years, and now because of the development of human medicine, the value of the blue blood in this thing has been discovered.

The "horseshoe crab" extracted from the blue blood contains copper ions in the blood of horseshoe crabs, which can accurately and quickly detect whether the internal tissues of the human body are infected by bacteria.

"Woo ......"

Once the honey badger's temper came up, no one could pull it, Qin Fengyi was holding this little thing of more than ten catties, its body was suspended and it was still struggling.

I'm going to it!

Big animal, hurry up and spread me!

"Roar~!"

In terms of obedience, it was the most obedient, and it was the first to read its master's mind, holding the horseshoe crab in its mouth, and finally putting this prehistoric creature into the sea.

"Blue blood contains copper?" Lin Qingxue was muttering softly, and then she looked at Qin Fengyi incredulously.

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

"I'm telling you, cucumbers are tough, but they can reach the stomach in one step!"

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

"I'll go, Qin Fengyi, you're a scumbag. Lin Qingxue's eyes widened 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 amazing. Han Xuening kept this sentence printed in her mind, and when she thought about it, she felt super funny, and she completely hit the point of laughter.

"His kidney ......" Lin Qingxue's face was bitter, she was worried about her fate tonight, she murmured sadly, "His kidney is definitely alloy steel ......"

The "horseshoe crab" extracted from the blue blood contains copper ions in the blood of horseshoe crabs, which can accurately and quickly detect whether the internal tissues of the human body are infected by bacteria.
