"microscope."

Lu Yuan said with a smile.

"microscope?"

Huang Feihong looked around the microscope curiously.

"As the name suggests, a microscope is an instrument that can magnify extremely small things enough for people to observe."

Lu Yuan smiled and asked: "I remember Brother Huang asked me a few days ago why I only drink cold boiled water when drinking water, right?"

"That's right. I remember that Brother Lu advised me not to drink water from the well in the future."

Huang Feihong nodded, and then he asked thoughtfully: "Could it be that this has something to do with the microorganisms Brother Lu wants to talk about?"

"exactly."

Lu Yuan put the two jugs in front of Huang Feihong, and said, "Brother Huang, please look at the two jugs of water in front of you. The one on the left is freshly boiled water, and the one on the right is from the water tank. raw water."

As he said that, Lu Yuan took a drop of raw water with a dropper and put it on the glass slide, then put it under the microscope and adjusted the magnification: "Brother Huang, you can take a look."

"Oh?"

With curiosity, Huang Feihong put his gaze on the eyepiece.

"what is this!"

After seeing the constantly swimming and rotating microorganisms of different sizes in the microscope, Huang Feihong took a step back suddenly, his face turned pale.

"That's microbes."

Lu Yuan smiled and explained terms such as bacteria, fungi, and algae in words that Huang Feihong could understand.

Listening to Lu Yuan's explanation, Huang Feihong's complexion gradually improved, but when he saw the tiny creatures in the camera again, his expression was still full of shock: "Brother Lu, could it be that... the water we usually drink , so there are always so many... microbes?"

"exactly!"

Lu Yuan nodded. Immediately, he took out another glass slide, put a drop of boiling water on it, put it under the microscope, and then stretched out his hand to signal: "Brother Huang, you might as well take a look at this again."

"it is good!"

Knowing Lu Yuan's intention, Huang Feihong looked closely through the eyepiece again.

"Sure enough, there are not so many microbial activities in this drop of water!"

After Huang Feihong raised his head, he said with excitement in his eyes.

To be honest, when Huang Feihong saw so many microorganisms in the well just now, he was a little scared.

Because water is the source of life, people can live without many things, but they cannot live without water.

But there were so many hidden dangers in the water, which made Huang Feihong very powerless.

No matter how good his martial arts were, he was still helpless in the face of these microorganisms.

Fortunately, Lu Yuan found a solution in time——

Boil the water before drinking it.

Although there are still some microorganisms left in this drop of water, it is much better than the previous drop.

"Brother Lu, if it wasn't for you, Huang would probably still not know that we are so close to danger!"

Huang Feihong saluted Lu Yuanshen excitedly: "Huang wants to thank Brother Lu for his contribution on behalf of the entire Foshan, no, the entire Chinese nation!"

In his opinion, whether it is the microbiology taught to him by Lu Yuan, or the microscope in front of him, they should belong to the absolute sect.

He even felt that if Lu Yuan was willing, he could even start a sect and make his name in history.

However, in the face of such a huge temptation, Lu Yuan passed on this precious knowledge to him so generously and selflessly. How could this not make Huang Feihong admire and excited?

Hearing these words, Lu Yuan hurriedly dodged the ceremony, even though he thought he had an astonishingly thick skin, he couldn't help blushing from Huang Feihong's praise, and hurriedly waved his hands and said, "Brother Huang, I didn't invent this microbiology." Well, scientists abroad have already discovered these things, and I’m just a narrator.”

"Brother Lu, don't be overly modest."

Huang Feihong still insisted: "Even though some people from abroad have already discovered these things, I don't believe that foreigners are willing to impart such precious knowledge to us selflessly—Brother Lu, your achievements are no worse than those who discovered it!"

Lu Yuan was naturally still modest when he heard the words.

At this moment, Lu Yuan heard Aunt Thirteen's voice from outside the door: "Young master Lu, Feihong, what are you talking about, it's so lively?"

"Nothing, we are discussing some medical knowledge."

Lu Yuan explained with a smile.

Huang Feihong also nodded in agreement.

"What medical knowledge, can I also listen to it?"

Aunt Thirteen asked curiously.

"of course can."

Next, Lu Yuan instructed Thirteenth Aunt to observe the similarities and differences of the water droplets on the two glass slides.

Naturally, just like Huang Feihong, when she saw the difference between the two drops of water, Aunt Thirteen also screamed in surprise.

At the same time, he admired Lu Yuan more and more for being willing to pass on this precious knowledge to Huang Feihong without reservation.

She even admired Huang Feihong even more than Huang Feihong.

Because she has studied abroad for many years, she knows better than Huang Feihong how advanced and precious this microbial knowledge is.

Looking at Aunt Thirteen's adoring eyes when she looked at Lu Yuan, Huang Feihong sighed inwardly.

He heard clearly just now that after seeing the two of them, Aunt Thirteen called out the first name of 'Mr. Lu', and he was the second.

Of course, this may not explain anything, after all, Aunt Thirteen may be the first to call Lu Yuan because she saw Lu Yuan first.

but,

Seeing that Aunt Thirteen kept asking Lu Yuan various questions about foreign microbial scientists, and Lu Yuan answered fluently, but he couldn't get in the way, Huang Feihong knew that it was time for him to quit.

Naturally, Lu Yuan didn't know what Huang Feihong was thinking. Seeing that Huang Feihong was silent, he hurriedly said to Aunt Shisan: "Miss Dai, are you waiting for me to accompany you to take a photo? Brother Huang finished class."

"no, I'm fine,"

Huang Feihong forced a smile and waved his hands when he heard the words: "If you want to take pictures, go quickly. I think the weather today is not very good. If you go late, you may be caught in the rain."
