Listen to Zhang Defa's description.

Li Duoyu knew that it was "Blue Tears" coming.

In this era, there is no such thing as "blue tears", as if the term blue tears was deliberately beautified in the previous life for tourism.

Because blue tears often erupt on the eve of the Midyear Festival, many old fishermen call them "ghost fires on the sea".

Thought it was the "good brothers" who came back.

In addition, when blue tears erupt, it will lead to the death of fish and shellfish, and the catch will also be significantly reduced.

The old fishermen thought it was the "good brothers" who ate the souls of the fish and shellfish.

So blue tears burst out of words.

Fishermen do not go out to sea at night.

And as soon as it gets dark, parents will call all the children back and not let them play outside.

Li Duoyu, who has lived for two lifetimes, naturally knows what "blue tears" are all about.

Speaking of which, Li Duoyu really has to thank the short videos, if there were no these short videos, he really wouldn't necessarily know what Blue Tears were.

In fact, blue tears are mainly caused by two species of marine plankton that glow, the "Hiss" and the "noctilucent algae".

The "Hiszi" is a mesomorph that is so small that it is not visible to the naked eye, and it lives mainly in shallow sea areas.

If there is only blue light near the beach and there is no other place, it is likely to be "blue tears" caused by sea fireflies.

The blue tears caused by sea fireflies are generally harmless, and farmers generally do not have to worry.

What really scares farmers is the kind of blue tears that are very bright as soon as the boat drives over.

These blue tears are often caused by "noctilucent algae", a marine dinoflagellate that, when stimulated, emits a blue light.

But what is really harmful is not noctilucent algae, it is just a signal before the red tide erupts.

The appearance of noctilucent algae often indicates that there is a problem in the water body, and the algae have begun to bloom.

Algae blooms can cause red tides, which can be harmful to fish and shellfish.

For farmers like Li Duoyu.

When the red tide first broke out, it was not terrible.

What's really scary is when the algae die in large numbers after a red tide erupts.

Because after the death of algae, in the process of decomposition, a large amount of dissolved oxygen in the water will be consumed, which will directly lead to the death of fish and other marine organisms due to lack of oxygen.

It will also release a large amount of toxins, pollute the marine environment, and when it is serious, the sea water feels sticky to the touch, and it smells very fishy.

As soon as I heard that someone had eaten shellfish and caused diarrhea, Li Duoyu already knew that there were already a lot of harmful algae in the seawater.

However, Li Duoyu did not panic.

Even if the red tide would cause a mass death of his oysters, he could accept it.

Going out to sea to fish is God's reward for eating.

And those who engage in breeding like them are grabbing food from God, and the risk is naturally very great.

It's normal to have wins and losses.

There is no profitable business, and there is no breeding without problems.

Li Duoyu asked Zhang Defa: "How was the exam, it's August, and the results should come out." ”

Zhang Defa sighed:

"There are no problems in other subjects, and I didn't do well in the foreign language test."

Li Duoyu frowned and said, "Didn't get in?" ”

Zhang Defa sighed: "It's not that I didn't pass the test, but the score I got was not very ideal." ”

Li Duoyu frowned and said: "Grinding and chirping, just say how many points you have in the test, and which school you go to." ”

Zhang De sighed: "More than five hundred, I couldn't get into your sister's medical school, I only applied for Rongcheng Medical College." ”

Li Duoyu exclaimed: "More than five hundred is quite high, and our Rongcheng Medical College is also a very good school, I thought you only took the exam more than two hundred." ”

Zhang Defa said disgustedly:

"Don't compare you to me."

They are well aware of the benefits of doctors, high-end equipment, and only the best schools can access them.

Rongcheng Medical College is good, but compared with the school that Xiao Rong attends, the gap is still quite big.

Zhang Defa said: "By the way, I've been away for so long, and there are no other doctors coming to our island?" ”

"Now there is a shortage of doctors, there are not enough doctors in the health center, where are there still doctors to come to our island."

Zhang Defa frowned and thought for a while: "If I am really admitted to Rongcheng Medical College, I will come back to help during the holidays." ”

As a village director, Li Duoyu naturally hopes that Zhang Defa will often come back to help see a doctor.

But this is not good, Zhang Defa will definitely stay in Rongcheng as a doctor after graduation in the future, and Dandan Island still has to find a doctor who is resident on the island.

Li Duoyu snorted:

"Don't think you are important, when the economy of our village develops, maybe all the doctors will rush to come to our village, and when the time comes, if you want to come back, I'm afraid there will be no place for you."

Zhang Defa was stunned for a moment, and then smiled awkwardly, he felt that Li Duoyu's words were really possible.

"This year, our village has really changed a lot."

Li Duoyu said: "You just found out, when you graduate from college, our village may be full of 10,000 households, and every family will build a mansion, and when the time comes, you will know that you are running the wrong track." ”

Zhang Defa pursed his mouth: "No matter how rich you are, what's the use, if you are sick, you have to find a doctor like us." ”

"Makes sense." Li Duoyu nodded and said, "By the way, Defa, I've been really sick recently, you can help me take a look." ”

Zhang Defa was puzzled: "I see that your face is very good, not like you are sick." ”

Li Duoyu said seriously: "These days, my blood and qi are surging, my lower abdomen is restless, and I wake up every day like the middle of the day.

After hearing Li Duoyu's words, Zhang Defa, who was still a single dog, had a black face and took out a large syringe on the spot:

"Director Li, you are really sick, come and take off your pants, I'll give you a kick shot."

After seeing the big needle, Li Duoyu ran away directly: ", your needle is used to beat pigs." ”

Zhang Defa squinted.

"Hit your pig, just right."

Li Duoyu waved his hand.

"Let's go, I have time to come to the village committee to make tea with me, but it's a pity that you study medicine, if you learn breeding, maybe, I will become your teacher."

Zhang Defa furrowed his brows, not understanding what Li Duoyu was talking about at all.

……

When Li Duoyu returned home, A-Niang had already cooked the meal.

Due to the heat in summer and a few more mouths, A-Niang directly set up a table of eight immortals and ate in the courtyard.

Xiaoying took Tutu to play in the courtyard, and Li Shuihua, the sister who had just come out of confinement, came out to enjoy the shade with the third child.

The eldest Zhang Lin and the second Zhang Yun helped serve the dishes, and after the two girls saw Li Duoyu, they said sweetly: "Third uncle, okay." ”

Li Duoyu touched their heads: "Are you still used to living on the island?" ”

The two little girls nodded and said, "It's much better than our village, here, no one dares to bully us." ”

Li Haoran on the side sighed and muttered: "Your uncle is the village director, and your aunt is the head teacher of the school, who dares to bully you, thank God for not bullying others." ”

When the meals were all on the table, Lao Li and his brother-in-law happened to come back with a dustpan.

After seeing the two come back, the eldest and second immediately stepped forward and wanted to help pack their things.

"Ah Gong, are you thirsty, do you want to drink tea?"

"Is your shoulder sore, do you want me to give you a beating on the back?"

"No, no."

"These dustpans are all dirt and dirty, don't touch them, wash your hands and go to eat."

Lao Li is very happy when he sees these granddaughters these days, and he always has a straight face in the past, but since these two granddaughters came, the smile on his face has obviously changed.

Li Haoran, who fell out of favor a little, pouted: "Two sycophants." ”

Li Duoyu, who had been paying attention to Xiao Chubby Dun for a long time, walked over and touched his head.

"Haoran, you are a new generation, the oldest, you have to take good care of these younger brothers and sisters."

Seeing the uncle talking to him, Li Haoran nodded happily: "Uncle, that's for sure, with me, no one in our village will dare to bully them." ”

Li Duoyu looked at these nieces and liked them very much, and couldn't help but sigh with emotion: "It's better to have a daughter." ”

Li Haoran on the side heard it.

Freeze in place for a few seconds. (End of chapter)
