The graduate dormitory where Chen Ming lives is only separated from Mu Xiu by a wall. Looking out from his desk, you can see the entry and exit of the dormitory No. 16. He saw that Mu Xiu had a few more friends from being alone, which was completely different from what Liang Yao said about his introverted personality.

Moreover, Mu Xiu looked pretty when she smiled. Chen Ming raised his lips when he thought of the contacts he had in experimental classes these days.

"I don't know what kind of small animals will be dissected in this experimental class?" Ma Shulan said with a frown.

"This time I heard it was a frog experiment." Huang Rou tilted her head and held the book in her hand.

"Go quickly and see Senior Chen Ming." Liang Zhenzhen said with some anticipation.

"I've been thinking about you, Senior Chen Ming, all day long, and I don't know if they know who you are?" Ma Shulan made fun of Liang Zhenzhen.

"He smiled at me last time, of course he knew who I am." Liang Zhenzhen looked like a fanatic.

"Okay, if you don't go, you'll be late." Mu Xiu smiled and pushed Liang Zhenzhen.

The four of them went to the laboratory classroom with a chat and laughter.

After the previous experimental classes, after the change, the four of them were members of the group. Chen Ming had been standing on the podium with a basket in his hand. When he saw them coming in, he showed a bright smile.

Liang Zhenzhen also replied with a big smile. Huang Rou and Ma Shulan looked at each other and smiled. Mu Xiu buried her head and walked forward.

Chen Ming was speechless, why did anyone who hoped that there would be no response?

"Students, the experiment we did outside today was to observe frog contraction and compensatory intervals. Everyone was optimistic about the topic and Chen Ming began to distribute the experimental subjects." After Teacher Ma said on the podium, Chen Ming began to distribute frogs one by one.

When everyone prepared everything, the frog was tied up and the preparations were all done. Chen Ming stood in Mu Xiu's group with interest and saw how they operated.

"Students, the purpose of our experiment today is to learn how to record the frog heartbeat curve. By giving stimulation at different periods of heart activity, observing the contraction and compensation intervals during the observation period, understanding the characteristics of myocardial excitability, and verifying the characteristics of urgent, effective and unresponsive periods. " After finishing our lecture, Teacher Ma took the lead in doing the experiment and explaining.

"First, destroy the frog's brain and spinal cord." Teacher Ma pressed the front end of his head with his index finger and pressed his thumb on the back. The frog's head leaned forward, held a probe with his right hand and stabbed the skin vertically at the occipital magnular hole at the posterior edge of the head, and then inserted the needle into the cranial cavity.

"Now, destroy the brain tissue in the skull cavity first." Teacher Ma skillfully used left and right to destroy it.

"Then the spinal cord is destroyed. Students see that the frog's limbs' muscles are stiff and disappear, the muscles are loose, the reflexes disappear, and there is no spontaneous movement. Now the brain and spinal cord have been completely destroyed. Let's start doing experiments." Teacher Ma explained in paragraphs, then shuttled back and forth to watch the students do experiments.

Because there are many frogs, each of the four-person team can operate once. Mu Xiu has solid basic skills and makes few mistakes, so she does it first, and there are any shortcomings to avoid the following people making the same mistakes.

"Wrong, the probe must come out and retreat to the occipital foramen, and then insert it backwards into the spinal canal to destroy the spinal cord. Mu Xiu, you can pull it back a little further." Chen Ming saw that Mu Xiu's needle was incorrect and quickly reminded him.

Mu Xiu held his hand firmly and slowly pulled the needle back a little. As Chen Ming said, it really entered the spinal cord.

In medicine, Mu Xiu is also a novice. Everything starts from scratch. In the past, those who have learned it once, and each time they are brilliant with high scores, and have become the past. Now, like all the classmates here, she is in contact for the first time, and she will have some things she doesn’t understand or can’t do well.

Chen Ming looked at Mu Xiu with praise, but unexpectedly, Mu Xiu had such strong understanding ability.

"Thank you senior." Mu Xiu raised his head, thanked him, and continued to do the next experiment.

Mu Xiu carefully held the glass minute needle and gently lifted the heart, exposing the frog's heart. He held tweezers in his left hand, clamped the pericardium, held tissue scissors in his right hand, and gently cut the pericardium to completely expose the heart.

This is not the first time Chen Ming has seen Mu Xiu perform an experiment, but he is surprised every time, because Mu Xiu is too steady, bold and meticulous, and seems to be quick to cut, but he has a very good grasp of the measure and always looks calm on his face.

For doctors, a stable psychological state is the most important thing. Mu Xiu stands there and gives people a feeling of peace and confidence.

Mu Xiu connected the electrodes to the frog's heart and began to collect biological signals.

When the period of contraction is present and compensatory intervals are introduced, the experiment is perfectly over.

"It's my turn." Liang Zhenzhen saw Chen Mingzai and had a very strong desire to show off.

Huang Rou and Ma Shulan laughed in a depressing way, no one snatched her.

Liang Zhenzhen saw that Mu Xiu was doing so smoothly and simply, but when she got to her, she tied the frog's limbs and forgot what to do next. With the operation process, she really forgot about it step by step.

Fortunately, Chen Ming was more patient and reminded and guided step by step. Mu Xiu also stood by and watched. Soon, the table was terrible.

When Mu Xiu was doing the experiment, the tabletop was clean and tidy, while Liang Zhenzhen, when she destroyed the frog's spinal cord, hesitated to put the needle in the right place. She pulled the needle quickly and the blood splashed out on the tabletop.

Poor, the frog under Liang Zhenzhen has more than a dozen needle holes on her body, and it has not been solved yet.

"Mu Xiu, it seems that you are doing it very simply, why did I make a mess when I get started?" Liang Zhenzhen became a little upset and her hands began to rush around.

"Liang Zhenzhen, take a deep breath, calm down, and do experiments. The most taboo thing is emotional instability, which can easily affect judgment. Take your time and you will always succeed." Chen Ming comforted him in a nice voice.

"Yeah." Liang Zhenzhen was soothed by Chen Ming's gentle words, and her hands began to move smoothly.

At this moment, Mu Xiu suddenly understood why some girls liked puppies in their previous life. Chen Ming was definitely a puppies. He was young, sunny, gentle and understanding. Even she thought that Chen Ming was really likable.

After the experimental class, the four-person group stayed to clean up, and Chen Ming recycled all the corpses of the frogs.

"Senior Chen Ming, let's have lunch together." Ma Shulan said cheerfully.

Chen Ming paused in his hand, and for a moment, he smiled and said, "Okay, I'll invite four juniors."

"No, I'll ask. If it weren't for the senior's guidance, I wouldn't know if I could complete the experiment." Liang Zhenzhen said quickly.

"This is not possible. I have a meal subsidy for graduate school. I am a big man and have dinner with a few juniors. There is no reason to let my juniors treat you." Chen Ming's words once again added a lot of points to him.
