“That’s meaningless. ” Su Yun said,”humans have 46 chromosomes and gorillas have 48. It’s impossible for them to give birth to 47 chromosomes … Eh? Why are we talking about this?”

“It’s you. ” Zheng Ren fiddled with the patient’s sole hair with sterile gloves and pondered about how to solve this problem.

“It has nothing to do with reproductive isolation or genetic changes. I think it’s more like hair migration.” Zheng Ren picked up the hair on the sole of the foot and placed it on his finger.”It’s embedded in the outermost layer of the skin. As I walk deeper, it gradually stimulates the nerve endings of the thicker layer of skin on the foot.”

“Boss Zheng, please speak slowly.” Zhou Litao didn’t hear clearly, so he asked immediately.

“Why can’t I understand a single word?” Su Yun seemed to have forgotten the smell of the patient’s sweaty feet. She moved closer to Zheng Ren’s finger and looked at the extremely fine hair seriously. “You’re right. I remember that article. It was published by a Brazil doctor. “

“Brother Yun, what is it?” Zhou Litao asked.

“There are similar case reports in the [emergency medical visual journal]. I think that the hair of white people is soft, and the possibility of hair migration is not high.” Su Yun said,”normally, it’s more likely to appear in Asian people with more hair quality and harder hair.”

“But this hair … It’s a little soft,”

Su Yun moved closer and looked at the strand of hair that Zheng Ren was twirling in his fingers.

Zheng Ren was very worried that Su Yun would faint from the smoke like Lin Yuan. He looked at her for a while, and his eyes were already filled with tears.

It wasn’t a deep love, but the sour smell was too strong.

“Boss Zheng, just this?” Zhou Litao looked at a strand of hair on the sole of his foot in confusion. It was really difficult to associate the patient’s severe pain with it.

Zheng Ren then used his other hand to touch the root of the hair.

“Ouch …” The patient immediately cried out in pain.

“Does it hurt that much?” Su Yun asked.

“It hurts … It’s not that painful, but I’m used to it,” “As long as you put a little strength into it, it’ll hurt when you touch it,” the patient said, a little scared.”I … I’m not pretending.”

“I know. The hair penetrated the cutillum and extended to the depths of the foot, touching the peripheral nerves.” “Looking at his state of pain,” Zheng Ren said softly,”I’ll consider that the hair went in deeper.”

“Use the tweezers, let me do it.” Su Yun said.

“Don ‘t.” Zheng Ren said,”take it under the microscope.”

“Aren’t you making a mountain out of a molehill?” Su Yun asked in confusion.

“I’ve read the article in the ‘visual Emergency Medicine’. Since the patient is a white man, his hair is softer, so we can just use a pair of forceps to remove it. I think he should be careful with this one. Once the hair is left in the deeper layer, it’ll be very troublesome to take it out. Even if we cut it open, we can’t find it. “

Zheng Ren said what he was really thinking in all seriousness.

The patient sat on the bed and listened in a daze. He was still thinking about the reproductive isolation between humans and gorillas that had just been mentioned.

What was this about? her heel was hurting, so why did she have to go so far?

“Alright, put on your shoes and follow me to the treatment room.” Zheng Ren said.

“Doctor, what are we going to do?” The patient was stunned for a moment before he asked in a low voice.

“Its hair fell off and was stepped on by you. It then penetrated the cutillum and entered the peripheral nerves.” Zheng Ren said,”you need to’ pull ‘that hair out before you can recover.”

The patient still did not understand. He felt that the young doctor in front of him was a little young, but he had a strong aura, the kind that he could not question.

He put on his shoes, tiptoed, and limped to the treatment room.

“Lin Yuan, go to the operating room and get my microscope.” “If there’s another … Forget it, you can contact Yiren. I still need to … I’ll do it myself,” Zheng Ren said.

Zheng Ren might have felt that it was too troublesome to explain things little by little, so he said a few more words to the patient before he turned around and left.

Lin Yuan looked at Zheng Ren in surprise as he left. He went to find the surgical equipment himself and asked in a low voice,””Big brother Yun, what is boss Zheng doing?”

“You’re making a mountain out of a molehill. ” Su Yun said,”just pull it out with a pair of tweezers. He insisted on cutting the cuticular layer under a microscope.” Think about it, how thick is his hair?”

” 60 90 microns.” Lin Yuan said without even thinking.

“That’s right, it’s less than 1/10mm. Your boss Zheng is so awesome, he’s going to perform a surgery without bleeding. ” No matter what Su Yun said, he would not speak properly. The mocking tone in his mouth was so thick that it could not be dissolved.

“Brother Yun, you won’t bleed?”

“Cut open the cutillum. The cutillum at the bottom of the foot is slightly thicker, and it’s estimated to be around 100 microns. Then, go to the hair-growing layer. The adhesion between the body tissue and the hair there is not as serious. Then, pull out the hair. “

“……”

Lin Yuan took a look at the patient. It was just a patient who came to the emergency department for treatment. No wonder big brother Yun said that boss Zheng was making a mountain out of a molehill.

The patient sat quietly on the bed in the treatment room and waited. Soon, he saw the young doctor return with a metal surgery box.

When he put on the surgical microscope, opened the surgical box, and took out a small microsurgical instrument, the patient’s eyes were fixed on Zheng Ren, who was full of a sense of technology. There were countless questions in his heart.

Before he could ask, he heard Zheng Ren say,””This is the black line in the skin. We need to distinguish it from the migration of parasites.”

“If it’s a parasite on the surface, there won’t be a fixed pain, and the itch will be very serious. With this experience, you’ll know what to do next time you encounter a similar situation. “

As he spoke, the patient saw Zheng Ren install a small blade on the handle of the knife. It was so small that it looked like a child’s toy. However, the blade reflected the light and gave off a cold glint, which made him feel a little afraid.

Although he was a little scared, he tried to comfort himself.

It’s fine, it’s fine, we need anesthesia no matter what. He just didn’t know how thin the needle needed to be to anesthetize with such a small surgical blade.

It was wrong! Why didn’t I see any anesthesia needles? There was more! He didn’t see any anesthetics!

The patient was stunned for a moment. Before he could understand what was going on, Zheng Ren had already placed the knife aside and picked up a pair of tweezers.

“Doctor, do we not need anesthesia?” The patient asked nervously.

“I’m done. I don’t need anesthesia. ” “It’s fine,” Zheng Ren said indifferently. Then, he looked at the strand of hair that he had just removed under the light.

“This is …”

“You’re the one who’s walking barefoot at home, stepping on hair. This strand of hair will drill to the bottom of your feet and Pierce into your body like a needle. ” Zheng Ren laughed and twisted the hair onto a piece of sterile gauze. He then handed the gauze to the patient.
