The campus environment of Beijing University is beautiful and elegant, rich and colorful, and the air is fresh.

The original two-person sisters, because of Ye Yun's four friends, became a six-person line.

Compared with Ye Yun, an academic scholar who is not reading books in the library every day and not doing experiments in the laboratory, these four friends are obviously more down-to-earth and more suitable for being tour guides.

Everywhere he went, he was scrambling to introduce Ye Fan, and his enthusiastic appearance was more like Ye Fan's sister compared to Ye Yun who was tied next to him.

Every now and then, in order to show her status as her own sister, Ye Yun always has to make a sound brush up on her sense of existence, and use her genius and poisonous tongue to introduce it again in another more profound tone art, and her four concubine friends were stunned for a moment, and a long and knowledgeable expression said that they refreshed their new understanding of the school.

The only place in the school that doesn't need to be introduced by four friends is the laboratory building where Ye Yun stays almost every day.

Ye Yun was supposed to be in her senior year this year, but in fact, she had already started to study in graduate school, and in her sophomore year, she finished her credits, and began to study in graduate school in her junior year, concentrating on following her mentor to do science projects, and began her life in the Tiantianwo laboratory.

And she's not a real nerd, she won't be autistic and will only be accompanied by experiments, she has brains, means, and force, and she is already a second-in-command in emerging projects, and the level of projects she participates in is getting higher and higher, and she has long been favored by the science above, so she is getting busier and busier.

Ye Fan didn't know much about her sister's situation in school before, after all, those scientific experiments sounded too tall to her, even if she was smart now, she couldn't understand it.

So listening to her sister's eloquent talk, Ye Fan's head continued to empty, and finally, I don't know which point touched her string, and several cases of murder and dismemberment that happened in the laboratory that she had seen appeared in her mind.

"What are you thinking?" Ye Yun stopped talking when she saw her obviously distracted, was what she said so boring? Look at the introduction of her friends, she listened attentively, when she said what she said, she actually directly distracted her? If she didn't want to maintain her image of a gentle sister in front of her friends, she would definitely reward her with a chestnut.

Ye Fan happened to analyze the case of the corpse shredding there in his mind, and replied casually: "I'm thinking, the xx laboratory corpse mutilation case, the murderer broke the victim's body in the laboratory, used the chemicals in the laboratory to corrode the victim's face, and soaked his palm in formalin......"

"Vomit ......" she described it too carefully, and the four friends turned pale, endured and endured, couldn't bear it anymore, and turned their heads and retched one by one.

"Shut up. Ye Yun took a deep breath, suppressed the tumbling in her stomach, and pursed her lips with a bad face.

Ye Fan was talking energetically, when he was suddenly stopped by the sharp and majestic voice, habitually paused, looked at Ye Yun blankly, blinked, and then saw their pale faces, as well as the movement of covering their stomachs in discomfort, and puzzled: "What's wrong with you?"

Huang Guifei, one of her friends, waved her hand, looked at Ye Yun indescribably, and then looked at Ye Fan sadly: "I take the liberty to ask, what major does Sister Fan study in college?"

In a trance, they recalled that Ye Yun was smiling for a while, as if to say that her sister was very good at taking the G provincial top exam, and she was still on the national list, at that time they were still envious and jealous of what kind of fairy scholar their sister was, and they were still waiting for her fairy sister to be a school sister for them.

Later, she said that her sister did not come to Beijing University, but went to A University, for the major she liked, what was the major she liked......

"Majoring in forensic science, I am a freshman majoring in A** medicine. Ye Fan straightened his back and said.

Damn, they're not mistaken, it's really a forensic science major.

As soon as the four friends heard this, their eyes were instantly full of admiration when they looked at Ye Fan, and their glances at Ye Yun were even more complaining.

My sister is not a person, and my sister is not a fuel-efficient lamp, they can't imagine such a cute and well-behaved sister, opening her mouth to break the corpse, closing her mouth and digging her heart, and disemboweling the corpse with a scalpel in her hand.

No, they want to throw up again.

"Sister Fan, you, a real cow ......" Concubine Wande, the second friend of her friends, stroked her chest and gave Ye Fan a thumbs up.

Ye Yun endured it, and a burst of chestnuts knocked on Ye Fan's forehead, and said with a dark face: "Okay, you Ye Xiaofan, you really have you, I will introduce you to the laboratory building of Beijing University, and you will talk to us about the laboratory corpse mutilation case?"

"Hiss......" Ye Fan covered his forehead and shook his head aggrievedly: "I didn't mean it, sister, I don't understand the scientific experiments you said, the environment here is extremely similar to the on-site environment described in the case, I can't help but think of the case analysis I just watched......"

After explaining, Ye Fan apologized to Ye Yun's four friends again, "Four sisters, I'm sorry. ”

Her pitiful and obedient appearance made the hearts of the four friends and sisters burst, and their hearts softened, and they all said: "It's okay, it's okay, this proves that Sister Fan is serious about studying and will definitely be an excellent forensic doctor in the future." ”

"Yes, yes, don't worry about your sister, she is timid, she is frightened, and she is angry with you, it is too much. ”

"Am I cowardly?" Ye Yun pointed to her nose and looked at the four friends who had defected on the spot with her eyes wide in disbelief and were talking nonsense with her eyes open.

"We weren't wrong, I was scared by my cowardice, and I beat our sister Fan, poor maniac, my forehead is red, you violent maniac. ”

"Yes, violent maniac, despise you. ”

The four friends were not afraid of Ye Yun's grinding teeth and glaring at all, and took the opportunity to make the times that they usually didn't dare to make in front of her sister, as a sister control, they were sure that in order to maintain the image of their good sister, they would not dare to resist them, so they could only let them do what they wanted, what they wanted, and what they wanted.

But they missed one thing.

"Hehe, have you been thinking about rebellion for a long time?" Ye Yun twisted her neck and looked at the four of them with a bright smile, her fingers clucking.

The four friends had a numb scalp, glanced at each other, and hid behind Ye Fan, unable to see the situation clearly, and grimaced at Ye Yun fearlessly.

Ye Yun raised her eyebrows and raised a gentle smile at Ye Fan.

Ye Fan, who was their shield, saw her sister's smile, not only her scalp was numb, but the hairs on her whole body stood up, and suddenly she dodged, and the two strides moved behind her, and said with a flattering grin: "Sister, do you need my help?"
