The sky sprinkled melodious moonlight pendants in the community, and in a certain household in the community, two middle-aged people were sitting next to the TV eating leftovers, and they didn't talk to each other much. And the characters on the TV are acting vividly.

"Dangdang~" The door rang.

The two middle-aged people are a little different, who will it be at this time? Lao Wang next door, or Lao Li from the other door to borrow something from him?

The middle-aged woman said to her wife, "Go open the door!" and say no, the two neighbors are not aware at all. ”

The middle-aged man also put down his chopsticks in annoyance, got up and walked towards the door, and when he opened the door and was about to scold, he was shocked by the person outside the door, and tears flowed out. The middle-aged man hugged the man at the door and kept banging on his back.

"Stinky boy, you haven't sent letters to your family for three years, do you know how much I miss you with your mother?"

The middle-aged woman sitting at the table quickly got up and looked at the door, and tears could not help but flow from her eyes.

"Dong'er, how have you been in the past three years? Why don't you send a letter to your family?"

The man named Dong'er said softly to the woman, "Mom~ In the past three years in the army, we can't contact the outside, we do all top-secret missions, and we can't contact the outside." I'm worried about you!"

The middle-aged man was not happy when he heard it.

"No matter how important it is, can it be as important as the two of us?"

He said that it was top secret, and he must have been afraid of leaking the news, and you still complained about him. The woman listened to her complaining about the child and became fierce against her, and the man immediately became well-behaved.

Dong'er came over and hugged her mother and said, "I won't go when I come back this time, I'm discharged from the army!" In the past two years, I have saved some money by relying on meritorious deeds and tasks, and I plan to come back to open a small shop and live an ordinary life. Oh yes! I came back just now and saw a very beautiful girl, upstairs in our house, I don't know which family it is, you have nothing to help me ask!"

"Upstairs, it's pretty beautiful!You stinky boy can't be a fancy to someone, right?" said the middle-aged man looking at Dong'er, who was a little embarrassed.

"Hey~ old man, who else is there a girl born in this building?"

"Yikes!"

The woman suddenly screamed, startling the two men next to her, and then said happily, "Hey~ Isn't it that Yang Hongyuan upstairs and the girl from their family are back?"

"I said, old man, why don't you go to their house tomorrow, if it really is great, that girl is a thief and sensible! Why don't you walk around more, mention marriage, and marry that girl into the door!"

Dong'er's face turned red all of a sudden, and she said embarrassedly, "Mom~ Don't talk nonsense, the girl doesn't know if there is a partner, and I won't leave when I come back this time, I'm just coming back to let you hold your grandson!"

"You stinky boy still know how to be shy, besides, if it is the girl's blessing, how good my son is!" said the woman, rightly.

Upstairs...

At this time, Yang Yang stood at the door, wanted to knock on the door but didn't dare to knock, and didn't come back once for almost two years, I don't know if her parents blamed her.

Suddenly the door opened, and a man walked out with a bag of garbage, and when he saw Yang Yang standing at the door, the garbage in his hand immediately fell to the ground, and then the old tears couldn't help but fall.

"Yang Yang is back~"

"Dad, I'm back, how have you and your mother been doing for the past two years?"

The man suddenly choked up and scolded, "You, you still know to come back!" but there was no blame. hurriedly pulled Yang Yang into the room.

The woman who was eating melon seeds on the sofa looked at this place suspiciously, who came back and her husband would be like this? When Yang Yang walked in, the melon seeds in his hand fell to the ground, and the tears in his eyes began to roll non-stop. hurriedly walked over and hugged Yang Yang, and kept patting Yang Yang on the back.

"You white-eyed wolf, you want to die!"

Then he began to pull Yang Yang to sit on the sofa and ask this and that. Looking at the appearance of his mother and father, a big stone in Yang Yang's heart was put down.

I talked to my parents until late before I went back to my room to sleep, and I felt that I could sleep soundly when I went back to sleep at home. After falling asleep, a shallow smile leaked from the corner of Yang Yang's mouth, and there were two small dimples, which were very charming.

Wake up early the next day...

After Yang Yang got up and washed, he told his parents about going to school. When I left home and was going down the stairs, I saw Shang Dong who was going out to exercise.

Shang Dong greeted politely and gently, "Hello!"

"Hello!" replied Yang Yang with the same gentleness. But Shang Dong was electrocuted by Yang Yang's voice.

"Do you live upstairs?"

"That's right!"

The gentle Shang Dong gave Yang Yang a very comfortable feeling, and he had a good impression of nothing.

Shang Dong continued, "That's a coincidence, I live downstairs from your house, and I'm a neighbor!

"Yes, I'm going to school now, and you'll come to me another day!" Yang Yang smiled brightly and left the corridor.

Shang Dong looked at Yang Yang's back blankly, and said to himself obsessively, "It's so beautiful!

The door behind him suddenly opened! Shang Dong's mother scolded, "Go and exercise, remember to come back early at noon." ”

......

After Yang Yang came to the university, he began to think back and remember that there was an old professor named Zheng Shan who studied blood and was an expert in blood. It seems to remember that people's evaluation of him is not very good, he is in a strange mood, and he is not close to people, and if he is asked, he will not tell himself.

Walking towards the teaching building of the faculty of medicine, I asked many students along the way. As soon as he asked the boy, he would ask Yang Yang for the phone number, and Yang Yang could only ask the girl. But when I asked the girl, I was met with a different look. It took a few twists and turns to find out the location of Professor Zheng Shan.

And Yang Yang also inquired about something. Professor Zheng Shan has a special hobby, that is, whenever someone asks him a question, he will draw 100 milliliters of that person's blood, and if it is a girl, he will also have an aunt's towel, which must be fresh. If it is a boy, in addition to having blood drawn, you must also strip naked for a checkup.

Yang Yang stood downstairs in Zheng Shan's laboratory building, and couldn't help but start to feel creepy, thinking that this old professor was going to touch his arms with his wrinkled hands and his aunt's towel. Yang Yang wanted to kill him, but in order to help Ling Feng ask some information, he gritted his teeth and walked in.

"I endured it, brother, if you can't survive well, you are sorry for the sacrifice your sister made for you!" Yang Yang said as he walked with his arms raised, constantly cheering himself up.

It suddenly occurred to me that it would be a few days before I could come to my aunt, what if this old pervert didn't agree. Yang Yang's head suddenly became bigger, but he couldn't go back without knowing anything!

Then he gritted his teeth and continued walking.

。。。

This laboratory building is not large, only two floors. On the first floor there are many rooms with big numbers hanging on them, from 01 to 10.

Yang Yang looked room by room, every time he had a room, there would be a layer of goosebumps on his back, because every room seemed to be filled with the smell of blood, and the entire corridor was extremely quiet.

When Yang Yang walked to the door of the room with 10 hanging on it, Yang Yang began to tremble.

There was blood on the handle outside the house!

Yang Yang looked at the handle that was sticking to the bloodstains and seemed to be turning, and the door suddenly opened, Yang Yang was suddenly shocked, and his body trembled even more.

An extremely obscene old man poked his head out of it and stared at Yang Yang obscenely.

"Ah~"

A violent scream rang out, but the students outside the laboratory building didn't react at all, because such screams are often heard here, and sometimes the screams of men can be heard. So no one is surprised by Yang Yang's screams.

"Smack!"

Yang Yang slapped the obscene old man with his backhand, and five finger prints quickly appeared on the obscene old man's face.

A voice that was extremely inconsistent with the current plot sounded, "Come in~"

There was no rage! There was no fight back! The obscene old man walked straight back. Yang Yang had some differences, and then plucked up the courage to walk in, and as soon as he entered, he was choked by the smell of blood.

"Ahem~"

"Why are you still stunned? Come in!" The obscene old man saw Yang Yang walking out, and hurriedly called Yang Yang back, because at this time, the obscene old man's heart was only thinking:

"She looks so beautiful, her voice is so good, her body is huge and perfect!"

The obscene old man enthusiastically said to Yang Yang, who had just walked in, "This classmate~ Is there any problem?"

However, no matter how much he tried to hide it, he couldn't hide the obscene aura of the obscene old man, Yang Yang's disgust rose from the soles of his feet to his brain, but he replied helplessly, "Hello professor, I want to ask you some questions about blood structure, is it convenient for you?"

"Convenient! Of course it's convenient!Come on, come on~ Let's draw a hundred milliliters of blood first, this is my rule!" Professor Lewd continued to say obscenely.

Yang Yang walked over with some twists, and his heart was a thousand, ten thousand unhappy!

"Why are you stunned? Take off your clothes! Roll up your sleeves and we'll draw blood. ”

At this time, Yang Yang's heart was about to scold Ling Feng to death, how could it be a blood problem. Slowly dragged his coat away, leaking out his white and tender arms. And Yang Yang is wearing a white half-sleeve, which can make people drool with the curve.

Zheng Shan's saliva flowed violently, and it kept ticking on his shoes. Then he picked up a cotton swab, sucked a mouthful of saliva, slowly smeared iodine wine on Yang Yang's arm, and touched it with his wrinkled hand from time to time, and every time he touched it, Yang Yang fell a layer of goosebumps. Yang Yang felt that the goosebumps in his life had fallen out.

After a short but incomparably long time, Zheng Shan took his loot with satisfaction, carefully put it in a preservation box, and said to Yang Yang, "What else? Oh! Look at you didn't come, so let's do it, I'll answer half of your question, and I'll answer you when your aunt comes." ”

"This ......"

"You don't ask me to go to work" Zheng Shan said and was about to get up and leave, Yang Yang was suddenly anxious when he saw it, the advantages were all taken advantage of, you actually want to leave like this.

Hurriedly said: "I want to ask what in the blood leaving the body causes death." ”

The obscene wrinkles on Zheng Shan's face were instantly replaced by seriousness, and none of the students here were interested in the composition of blood, and they were interested in how to kill people.

"It's not school knowledge, why are you asking this?"

Yang Yang told Ling Feng everything from beginning to end, and finally told Zheng Shan what Officer Du said.

Zheng Shan saw that he was wrong, so he told Yang Yang about the composition of blood, and Yang Yang listened intently, for fear that his sacrifice would be exchanged for a useless answer.

"Blood contains three kinds of cells: blood spirit, blood armor, and blood sac, which are three kinds of cells that cannot be fused, and can only be inherited. ”

"The blood spirit can make the body have strength, the blood armor can increase resistance, and the blood sac is the foundation of the body's recovery. If you don't have any of them, you can live, but you lose your normal function. ”

"If you lack the blood spirit, you will become weak and weak, and if you lack the blood armor, you will become very easy to get sick and cannot heal yourself, and if you lose the blood sac, you will not be able to be injured, and once you are injured, you will not heal yourself, resulting in the phenomenon of non-stop bleeding. Blood is an important part of the body, the body needs the operation of blood to maintain function, if the blood can not function, the body function stops functioning, such as too much blood lipids in the blood will cause the blood to flow slowly, such as dizziness, etc., are caused by blood. ”

"Then what is missing will die?" Yang Yang hurriedly interjected.

"Only if they are taken out in an instant, these three will die instantly!"

"Thank you for your answer, I think I already know what I need. Goodbye! Goodbye, not right, never again. Yang Yang immediately changed his face.

Zheng Shan said angrily: "How can you not keep your integrity?"

"It's not that I'm not honest, but what you want is too perverted, since I have already got what I want, I won't give it to you!"

"You know what! I think my aunt can know a lot from it. For example, if there is any gynecological disease or something, or if there is something wrong with the body, you can see it, do you think this is just a simple aunt towel, if it weren't for the beauty of your little girl, I wouldn't tell you so much. ”

"I'm pretty, that's why!"

Zheng Shan was poked in the center and began to lie in the skin.

"Whatever you want, obscenity is obscenity, but I am a professor, and it is my duty to solve problems for students, do you understand? It is also my duty to care for students' bodies! Why do you people outside misunderstand me like this, you see that there must be something wrong with your body emaciation. ”

Zheng Shan's gaze went from Yang Yang coming in to asking the question just now to now only for a moment, when he was answering Yang Yang's question, and the rest of the time he was staring at Yang Yang's chest. The old rascal has a tight mouth under his eyes, but his knowledge is a real talent.

Yang Yang didn't want to continue to theorize with him on this topic, anyway, he wouldn't give him his aunt's towel. Quickly turn around and leave.

When Zheng Shan saw Yang Yang like this, he knew that there was no hope for this aunt's towel. The little girl in the past really believed it when he said this. When I took it, I realized that it wasn't like that at all, this old rascal just liked that taste... (Huh~ I'm disgusting to write myself!)
