picked up a pair of tweezers next to him, grabbed Xue Yongfu's toes and gently broke them a little, trying to see what it was, but he couldn't see anything clearly. Pen ~ fun ~ pavilion www.biquge.info

It would be nice to have a magnifying glass, and I looked around with a magnifying glass, and a magnifying glass appeared in front of me.

Xia Yuning took a magnifying glass and handed it to me, "You're looking for this, right?" ”

I took the magnifying glass and looked at her, and said, "Thank you!" and then took the magnifying glass and began to investigate the small black spots in the gap between Xue Yongfu's toes.

Through the magnifying glass, I looked inside the gap between his toes and saw that these were not small black dots.

I looked closely, and Mr. Li on the side asked, "What is it?"

I said, "The small wound that has been bitten by the bug is very small and dense, and it is difficult to see with the naked eye. As I spoke, I gave the magnifying glass to Mr. Li, and he took the magnifying glass and looked at it.

But I thought to myself, what kind of insect is left by such a small hole?

I felt familiar, but I couldn't remember where I had seen it.

"What kind of insect bite is this?, and the wound is so small?" asked Mr. Li.

I shook my head and said, "Teacher, I need to extract the upper and lower parts of his wound, and maybe I can find something under the microscope." ”

Teacher Li took a magnifying glass and looked around between Xue Yongfu's toes, then put down the magnifying glass in his hand and said, "Approved." ”

Several students next to him looked at each other and sighed, they never thought that Xue Yongfu could still find a small wound that had been bitten by insects, and it was found by me.

After being approved, I carefully took the instrument and extracted the test sample, put it in a container to thaw it, and then came to the microscope.

I learned how to use a microscope from books, but I still don't understand how to use it.

I thought about asking them to come, but I saw Xia Yuning coming over with a notebook, and she said, "Teacher Tian, your eyes are uncomfortable, let me help you observe." ”

I nodded and agreed, but I was surprised that she actually called me a teacher, and I thought to myself that I was just a student who had only been in school for a few days, and you had been graduating from graduate school for several years.

I thought so, but I didn't refute it, and walked to the side and sat down with Mr. Li, looking at the big screen in front of me.

The microscope is connected to a large monitor, and the image observed under the microscope is transmitted to the monitor.

I looked at the monitor, the picture gradually became clearer, and I saw Xia Yuning holding a very thin needle and constantly flipping, so that all the small black holes could be exposed under the microscope, and the technique was very professional.

The technique is so professional, I really can't compare with her.

At this moment, one of the small black holes displayed on the screen suddenly moved, but Xia Yuning flipped the sample again as if he hadn't seen it.

"Stop, don't move!" I hurriedly stopped.

Xia Yuning hurriedly stopped when she heard this, and asked motionlessly, "Teacher, what's wrong?"

I looked at the screen, walked up to me and said, "You try to flip it back, just one click." ”

"Go back?" Xia Yuning glanced at me and asked.

"Yes, back. I said intently as I looked at the screen.

Xia Yuning frowned, glanced at me, and then turned around and flipped back as I said.

I stared at the screen and commanded, "Yes, slowly, that's it! Slow, okay, stop!"

As soon as I stopped, Xia Yuning quickly stopped what he was doing, and then looked at the microscope, wanting to see what he found?
