"... I saw some shameless woman and called everyone disgusting." This is what song Fuwen said with a cold face and arms.

"I saw that the saliva when I was sick was thicker than usual." Sun Changsheng is serious.

"Saliva hangs on the glass, and the reflection of natural light is..."

Li Xun pushed away Jiang Wenjie, who was preparing to make a long speech on mathematical derivation, and rushed into the river feebly.

"Sir, xun'er's legs are still soft. Tell us what you want us to see, or senior brother Wenjie will get sick again!"

Jiang qianxia thought it was natural. He nodded hard and said to Liu Jie, who was also turning his eyes: "you stop Jiang Wenjie for a while and let him see it at last. Otherwise, he must dominate the equipment and let us not see it."

Liu Jie, who was ordered in the face of danger, hung on Jiang Wenjie like an octopus, which almost paralyzed Jiang Wenjie who was suffering from illness.

Regardless of Jiang Wenjie's protest, the people gathered around Jiang qianxia, and then closed the doors and windows at her command. After confirming that there were no "spies" in the house, she took out one from the void... I can't tell what it was.

Although it's hard to say, it can be seen from the precise small parts above that this thing is extraordinary - at least it's not uncommon for craftsmen to build it in the same way now, and it takes a year and a half.

Taking out this thing, Jiang qianxia was obviously excited. Like an artist ready to perform magic tricks and shake the burden to the audience, he shouted. He put the glass slide stained with her saliva on the stage, clamped it with a clip, put his eyes on the eyepiece, narrowed one side of his eyes, carefully adjusted the focal length, and then straightened up.

"See, this thing is called a microscope. As the name suggests, it is to magnify and display small things invisible to the naked eye!"

"... isn't this just a shelf with a few magnifying glasses? What's strange, sir?"

Since the establishment of the Liulichang and the Shihui hall, the students in the arithmetic class have not played less with magnifying glass, and there have been several times that improper use of magnifying glass almost caused a fire.

So Li Xun looked at it carefully and didn't take it seriously.

Jiang qianxia didn't blame him, but gently touched his head and said with a smile, "what you said is actually right. Since it's not rare, you'll see it with your senior brother Jiang Wenjie later."

The person who holds the privilege drives aside the people who don't know the truth who realize that they seem to have missed something, and then respectfully gives way to the curious grandson.

The focal length was adjusted. Sun Changsheng put his eyes together as Jiang qianxia had just looked. When he looked carefully, he widened his eyes in an instant.

"Well, there are so many things here! What are those messy things, girl!"

The old man's action was very funny. When he was frightened, his feet moved back involuntarily with his body, but his eyes were reluctant to leave the microscope. The whole person looked elongated, counseling and funny.

Before Jiang qianxia could answer, sun Changsheng turned his head again and looked carefully at the saliva in the glass slide with his naked eye - although it looks cloudy due to illness, it is only the kind of turbidity mixed with the color of soup medicine. Is it normal?

How can you see through this strange thing? There will be so many messy little things in it, and some will move! Can move!

At the thought that so many small invisible things have been in her mouth, sun Changsheng's eyes at Jiang qianxia are different.

"... what's your look! It's not only my saliva that has these things. Well, everyone has them!"

When Jiang qianxia blushed and jumped to explain, song Fuwen took advantage of sun Changsheng's absence, took advantage of it, directly padded his toes and leaned over, and then shrunk back in an instant.

His face was pale and his cheeks twitched strangely for a moment. Song Fuwen stumbled to one side and held the corner of the wall to vomit.

There are old medical immortals and song Fuwen as examples. The people behind them are like kicking a cat. They want to know what they can see, and they are afraid of ending up like song Fuwen. It's really tangled.

Just when everyone hesitated, Guli calmly came forward, observed for a moment with a standard posture, then looked up and smiled at Jiang qianxia, "madam, this thing is really strange. I'm very happy to know the more subtle side of madam."

Well, people don't hesitate to look at the saliva. Can it be more disgusting than the numbness of the cold-faced general? It doesn't exist!

Boundless took the lead in pushing Guli away, and the rest lined up in turn. Although there were disgusting and choking, on the whole, in addition to Li Xun's skeptical life, others remained calm in shock.

"Girl, you said a few days ago that you wanted to show us why people get sick. Is it because of those messy things?"

Sun Changsheng, holding a pen and paper in his hand, was obviously ready to listen to "Sir" for immediate answers.

Scratching his head, Jiang qianxia shrugged helplessly, "isn't that right? What you saw just now, there are bacteria, drug residues and various enzymes in the mouth, but the virus for treating diseases can't be seen."

"Some bacteria can cause disease, but others are beneficial bacteria. The virus that really causes disease is too small to be seen with this ordinary optical microscope. We have to use a more powerful electron microscope."

"Then take out the electron microscope!" After spitting out, song Fuwen used a martyr like attitude, so that Jiang qianxia didn't have to "worry about" him, and he could hold on!

Turning his eyes, Jiang qianxia stood up very straight, "I want to take it out, but first, I don't have the authority to buy it. Second, even if I have the authority to buy it, I can't afford it! You really think of me as a rich man? I tell you, I'm a real poor man!"

No matter how much people in the house despise her identity as a "poor man", Jiang qianxia is hiding in Guli's arms and pretending to be invisible.

After they reluctantly gave up, Jiang qianxia came to popularize science.

"In fact, observing saliva is very disturbing. It's not as intuitive as observing a single thing. But saliva has the benefits of saliva. At least now I tell you, everyone's mouth, whether you brush your teeth or not, contains hundreds of different bacteria. Some of these bacteria are good for your body, and some may make you a little uncomfortable. ”

"If you can't understand it, you can imagine tens of millions of small insects that you can't see with the naked eye, breeding and dying in your mouth all the time..."

"Vomit -"

Looking at a row of retching people in the corner of the wall, Jiang qianxia smiled like an old witch in a western fairy tale. Even Guli holding her couldn't help pinching her face, making her restrain.
