The butcher professor wearing a white king-size mask frowned dissatisfiedly when he looked at the expressions of those female classmates, if he had the opportunity to do experiments when he was in college before, I don't know how happy he was, and the places for studying and doing experiments in the past were all contested by the students, how could there be a classmate like the current one, they are like a rich young master, such a good hands-on opportunity, and the teacher will force the students to carry it out.

"Syringes." The butcher professor shouted, and Hua Feng on the side heard it and hurriedly handed the syringe next to him to the professor.

"A roundworm of about ten centimeters." Professor Butcher continued. When Hua Feng heard this, he calmed down his heart, looked at the roundworm that was ten centimeters long, and then put it into the glass tube with his hand, and picked up a slippery, thin and greasy roundworm, if it wasn't for the fact that he often caught loaches when he was a child, Hua Feng really couldn't pick up a roundworm so quickly, and now Hua Feng has also regarded the golden roundworm in his hand as a loach. When Hua Feng handed the roundworm in his hand, Professor Butcher took it, then put it on the test bench, picked up the syringe to absorb the air, and then pressed the side of the roundworm with his thumb, picked up the syringe and injected it into the roundworm. The roundworm that the student is now injected with a syringe will soon stop wriggling and will not know whether it is alive or dead.

"Knife." The butcher professor shouted, but Hua Feng on the side saw that there were many knives on the test bench, and he didn't know how to hand the knife to the professor for a while. However, when Hua Feng saw the professor's eyes staring at one of the knives blankly, Hua Feng hurriedly picked up the knife and handed it to the professor, the professor nodded with satisfaction, and then picked up the sharp tip of the knife and slid it from left to right, and the dissected roundworm was immediately split in half. Later, Professor Butcher took another earthworm and dissected it for the students next to him.

"This time, Hua Feng, you are completely dissecting this alone, and your time is to dissect a roundworm and an earthworm within ten minutes, and start counting the time." Professor Butcher said, then stood by and looked at him. The students on the side looked at Hua Feng with some disbelief, because even if it was the professor and Hua Feng just now, it would take ten minutes to complete this dissection experiment. And the students also know that the most important thing to do this experiment is to overcome their inner disgust and catch slippery roundworms and earthworms quickly. For Hua Feng, Hua Feng has regarded those sharp, long and slippery roundworms as roundworms, and earthworms themselves went fishing when they were children, and they often saw them, and they didn't feel anything, although they were wearing gloves, they still felt slippery and greasy, and they also smelled that fishy smell, so they didn't feel anything. And the children of rich families who grew up in the city once saw these wriggling roundworms and earthworms once upon a time.

Hua Feng began to take out a roundworm from the glass tube and put it on the test bench when the professor said to start counting the time, and then took a syringe to absorb the air, quickly pressed the roundworm that was wriggling, and injected it into the roundworm's body. Then, Hua Feng quickly took out a fat earthworm from the mud irrigation next to it and put it on the test bench, the syringe absorbed the disinfectant water next to it, and injected it into the earthworm's body, and when the earthworm no longer moved, he picked up another knife and cut it at the roundworm, because this earthworm was relatively fat, so Hua Feng easily dissected it, and when the dissection was opened, the black mud inside the earthworm was immediately exposed.

"Nine minutes and forty-six seconds." Professor Butcher picked up the stopwatch in his hand and looked at it, then looked at his classmates with satisfaction and said. When Hua Feng heard this, he just smiled slightly, and the classmates next to him looked at Hua Feng in surprise, unable to imagine what he could really do.

"Okay, Hua Feng and I have already demonstrated to you. Hua Feng had to dissect all the roundworms in the glass jar and the earthworms in the mud irrigation before the other students finished dissecting them. As for the rest of you, it's up to you to do the following experiments, and now everyone is in their own groups, and I'll be watching you all around. Professor Butcher said, then glared at the students who were still standing aside, and those students immediately returned to their group as soon as they saw the professor's expression. I started to do experiments like Professor Ho Huafeng of the butcher, but when the students wanted to take the roundworms in the glass bottle by themselves, they immediately couldn't do it. Especially those female students in the group, looking at the male classmates in the group with pitiful eyes, as if if you dissected those hateful roundworms and earthworms for me, I would belong to you tonight.

Ten minutes passed, and none of those classmates made the first move, but looked at me and glared at you. And Professor Butcher didn't say anything about these classmates, just hinted at them on the side.

"It's 15:30 a.m. Beijing time."

When those students heard that it was already 3:30 in the afternoon, it was less than two and a half hours before the end of school, that is, one hundred and fifty minutes, and according to Hua Feng's degree just now, it would take ten minutes to dissect a roundworm and an earthworm, so it would take at least two hundred minutes for each person to have twenty roundworms and twenty earthworms, that is, it would take seven o'clock in the evening at the earliest. And it hasn't started yet, and I don't know if I'll be able to finish dissecting the roundworms and earthworms here at eight o'clock. So those students from the countryside, after closing their eyes, and then did not hesitate to put their hands into the glass bottle to get roundworms.

However, they slowly realized that the roundworms wriggling in the glass bottle were not as easy to hold as Hua Feng just now, so some students did not take out the roundworms in the glass bottle for a few minutes. Some students wanted to pour out all the roundworms in the bottle, but they were frightened by one of them. The classmate thought he was smart, so no matter how many roundworms were in the bottle, he poured them into the test bench, and this was fine, so the poured roundworms kept wriggling on the test bench, and then kept wriggling around, and some even fell to the ground. The students in the group were dumbfounded at this time, and hurriedly caught the roundworms back into the glass bottles under the reminder of the butcher professor. And by this time, more than an hour had passed.

By the time most of the students had finished the dissection experiment, it was already past nine o'clock in the evening. So when those exhausted classmates went out, it was already night. The remaining students continued to perform the autopsy, and some female students even shed tears. Unexpectedly, today is more disgusting than the last time I visited those dead bodies. However, they could only insist on dissecting twenty roundworms and twenty earthworms before they could walk.

And Hua Feng has been dissecting since the butcher professor asked him to start. However, there were no less than fifty roundworms in the glass bottle he was now, so when he finished dissecting all the roundworms, he didn't know how many roundworms had been dissected on the test bench, and he didn't know how many earthworms there were in the mud irrigation, so when Hua Feng finished dissecting all those earthworms, he was now almost nine o'clock. If it weren't for the fact that his mental strength had improved a lot recently, he really had a feeling that he felt dizzy as soon as he raised his head and stood up. And there are many students who encounter this situation, and those students can only rest for a few minutes before continuing to dissect.

When the students finished dissecting, they all fled the lab, because they really didn't want to stay in the lab for a second. Even Chen Zining, who originally wanted to wait for Hua Feng, also had to go back to rest first. However, for the students, when they go back to their dorms, they will definitely not be able to eat and eat, and even sleep tonight, and the things they dream about may be those disgusting roundworms.

By the time the last group of students had fully dissected, it was already 10:30 p.m. So when that group of classmates left, only Professor Butcher and Hua Feng were left in the laboratory. Hua Feng and Professor Butcher brought a processing tank, and used clips to clamp the roundworms and earthworms dissected on the test bench into the tank one by one, and then the professor took them for unified treatment. Then clean everything in the laboratory and disinfect it before coming out of the laboratory.
