"... When it comes to precision-guided weapons, its appearance is a revolution in the history of human weapon development, and it is one of the three major systems of modern warfare. To give a few examples, the laser-guided bomb 'Paveway' used by the United States in the Vietnam War in 72 ', TV-guided bomb 'White Star Eye', etc. 74 years later, guided bombs and missiles are collectively referred to as 'precision-guided weapons' or 'precision-guided munitions' in the Western military circles, and their direct hit rate is above 50.00%. Precision-guided weapons are divided into There are two types of missiles and precision guided munitions, and precision guided munitions are divided into terminal guided munitions and terminal sensitive munitions. Guided bombs are also called guided air bombs, which are called smart bombs in the West. They were first developed by the United States in the 60s and modified from ordinary aerial bombs. , gliding bombs with guidance devices and pneumatic control surfaces, including laser guidance, TV guidance, infrared guidance, radio guidance, such as the US AGM-123A laser-guided bomb, GBU-15 TV-guided bomb, China's LS-6 guided gliding bomb And FT series guided bombs, French 'Matra'-250/400/1000 series laser-guided bombs, Russian KAB-500L/1500L laser-guided bombs, etc. The hit accuracy of the third-generation laser-guided bombs can reach 1m... "Qin Su stood on the podium, pointed at the data on the projector with an infrared light, and talked eloquently.

(The above content is excerpted from the first section of Chapter 13 of "Military Theory Course" edited by Meng Tiancai and Wang Wenjun, which was printed by National Defense Industry Press in 15.)

It is twelve o'clock in the morning, and the last session of the morning class is in progress.The course taught by Chi Yusuo is an elective course related to military weapons, and he is talking about guided weapons.

He studied weapons research at university, and he went to the special forces as a technician. He didn't expect to keep up with the mission inexplicably.Of course, his knowledge is still there, and it is more than enough to teach college elective courses.

After another ten minutes, the get out of class bell rang.

Chi Yu casually tidied up the scattered handouts on the podium, and turned off the ppt screen on the computer screen: "Okay, let's end get out of class, the next class will be called, please tell those students who are absent. I won't keep homework Now, you guys remember to prepare the end-of-class paper and ppt."

There were scattered voices of tidying things up below and a few feeble echoes.

Chi Yu looked at a few handsome guys who were sitting in the front row in class and collapsed after class, couldn't help laughing and asked: "What's wrong with you? It's rare that you look so weak."

One of the boys sighed greatly: "Teacher, we were dragged out for training this morning."

"I'm so sleepy, I don't even want to eat lunch." Another boy complained.

Chi Yu was amused: "I remember you still have training in the afternoon?"

"It's gone, can you survive training in the morning and training in the afternoon?!" Bustling voices.

Chi Yu could only shake his head: "Back then we trained in the early morning and had classes in the morning, training in the afternoon and lectures in the evening, and you didn't complain like this."

The boys in the front row were familiar with Chi Yu, and a few boys who didn't want to move came from the back row to the front row and asked, "Teacher, you also trained like this back then?"

"Otherwise how do you train? Military students."

"I thought the teacher was doing theory, just like those who are specially recruited and don't need training." A boy said this, and other boys also responded: "That's right, the teacher looks like he is doing scientific research of."

The military academy has special enrollment, such as one or two high-achieving students, who do not need a physical examination, and girls who are as precious as pandas, do not need such training.

Chi Yu was amused by them, and asked, "How do I look like a scientific researcher?"

The boys smiled and said, "The teacher is so handsome, full of bookishness."

Shaking his head, Chi Yu put all the handouts into his sports backpack and zipped it up.He was wearing a white shirt, slacks, and sneakers. He looked like an ordinary college student, and he stood out as a stranger in this military academy where all students were required to wear camouflage uniforms.He carried the bag on his back and said to the students who were still lying on their stomachs: "Okay, get up, the cafeteria is about to close, you don't really want to skip lunch, do you?"

"Teacher." A dark and thin boy asked, "Do you have a girlfriend?"

"what?"

"If I can't find a girlfriend even with such a handsome teacher, wouldn't I have to be single?" He pretended to lament.

A fairer tough boy next to him laughed at him: "You miss spring."

Chi Yu was amused, and said: "You still have the mood to fall in love, it seems that your training intensity is not enough."

As he spoke, his cell phone rang.

When I took it out, it turned out to be a string of unfamiliar numbers.

Chi Yu never answered an unfamiliar number, but now he had an intuition that he should answer this call.So he pressed the connect button, not noticing that the students below were secretly looking at him.

"Hi, I'm Chi Yu."

There came a low voice that suited his aesthetics, even though the voice was not loud, it clearly had a majestic and arrogant temperament over the phone: "I'm downstairs in your teaching building, come out to have a meal."

Chi Yu was taken aback, walked to the window and looked down, there was a familiar black SUV parked below: "How...how did you drive the car into our school?"

"It's very simple. I booked a seat at Zhenyu Pavilion on Zhongxuan Road, and I came down to eat. It's been a long time since get out of class." The other side said to himself.

Chi Yu was a little helpless: "You waited for me to finish class? Did you get my schedule?"

"Come down to eat."

"Okay, okay." Chi Yu couldn't hold back the man speaking in a deep and semi-commanding tone, so he could only respond.

When he hung up the phone and turned around to get his bag, those boys booed, "Teacher, did your girlfriend rush you?"

"It doesn't sound like much, but it doesn't rule out that the teacher likes girls with a flamboyant personality."

"Is there still a car, big money?"

"Oh, do you think the teacher is a little boy?"

Chi Yu put his backpack on his back and glared at them: "You guys are used to it, how many papers can I arrange for you if you have nothing to do?"

It was already 12:30 when I walked out of the classroom, and the sun was very bright outside.Chi Yu doesn't like the sun, but he doesn't like to carry an umbrella. Standing in the teaching building and looking at the car a few steps away, he frowned.

The door opened and a person could be seen sitting in the back seat.

Chi Yu ran out a few steps, shielding the sun with one hand, and got into the car.

He closed the car door before exhaling under the action of the air conditioner.Qin Su was sitting in the back seat, wearing a black shirt, black leggings and black leather shoes.The last time they met was when Qin Su sent him back to the dormitory after the mission was over. Although Chi Yu had left his contact information, he never expected that Qin Su would really call him, so he used the excuse of having dinner together.

Chi Yu recalled the only two meetings he had with Mr. Heilang...

It looks like it's seducing a terrific beast.

It was already half afternoon after eating.Chi Yu has no class in the afternoon, he is a little sleepy, in order to get back to the ranking, he has done a lot of tasks in a row these days, and he didn't have a good rest.It is not so much tired as it is a psychological burden.

Thinking about being a killer for three years, the sense of guilt is getting stronger and stronger.

Is the mental illness getting worse or getting better?Chi Yu yawned, and decided to consult the psychiatrist for the regular psychological assessment next month.

He looked out the window and asked, "Are you going to send me back?"

This is not the way back to school.

Qin Su casually pulled out a cigarette and lit it, took a puff, and then forced out a playful smile: "Your killer rank has risen to 27? Congratulations, you will be on the ranking list soon. There are new items in the armory. Don't you want to visit?" The two questions were in a declarative tone.

Chi Yu was stunned for a moment, and looked at Qin Su carefully from head to toe as if he had never known this person before.

Is this really the black wolf I know?

Wait, speaking of it, we've only met twice, and we can't say we "know each other"...

However, he can show such a private thing as the armory to someone who has met twice, this Mr. Heilang is really a guy who does not follow the usual path.

Or, is there a conspiracy?

Qin Su looked at Chi Yu with great interest, although his expression didn't change much, his eyes flickered a few times.His index and middle fingers are slender, with well-defined knuckles, and his complexion is a pale wheat color, cast a layer of gray in the car with dark glass.The way he curled his fingers slightly between the cigarettes was surprisingly attractive.He tapped aside with two fingers, seemed to be shaking the soot, and said with a chuckle: "Don't worry, although it's not a big arsenal, you will like it."

"For example?" Chi Yu raised his eyebrows and asked tentatively.

"Heh." Qin Su took a light breath of the cigarette, opened his lips slightly to let the white air spread from between his lips and teeth, squinted his eyes and leaned on his back with a decadent look, but the hostility and sharpness in his eyes betrayed him In his heart, "For example, a sniper rifle?"

"Sauer?" Chi Yuxin thought about the style.

"I thought you preferred BarrettM107?"

"I hate Barrett." Chi Yu complained in a low voice, his eyes gradually lit up, "To be honest, I prefer Accuracy international AW and AS50."

"You will be satisfied."

The black SUV drove to a well-known villa area on the outskirts of the city. It is famous not because of its luxury, luxury, but because of its quiet environment.This is not a luxury villa group.

The car drove into the depths of the villa area, and stopped at one of the several large villas in Linxi, which was half-backed by the mountain.The house has a large courtyard, which has not undergone much artificial decoration and looks vibrant.

Chi Yu didn't have much resistance to the fact that he was abducted to someone else's territory by a dangerous person with just a small bait.The sense of security that came from nowhere appeared from the first time he saw Hei Lang.It seemed that somewhere deep in his heart there were some memories that he didn't know, telling him that the black wolf was trustworthy.

So when he was teased and sent back, he wasn't too angry.

Gracefully accepts Heilwolf's help when nearly unable to leave the crime scene.

"Seriously, can the sniper rifle I selected really be taken away?" Chi Yu followed Qin Su into the villa and asked, "The varieties you mentioned are hard to buy even if you have money. "

"It's not about money." Qin Su sneered, "You can't afford it either."

"That's why I asked if I could take it for nothing." Chi Yu shrugged.

Qin Su looked back at him: "You are so courageous, little killer." He waited for a while, and waited for Chi Yu to walk beside him before pulling him into his arms.He is a few centimeters taller than Chi Yu, and when he lowered his head slightly, he just leaned into someone's ear and said, "It's impossible to take it for nothing...how about the compensation?"

Chi Yu's body is not very sensitive, but at this moment, he was unconsciously shivered by the wonderful killing intent revealed by the too close distance and breath, and the people around him.

He clenched his fist quietly: "Flesh compensation?"

Qin Su laughed: "I'm very interested in you."

"That interest in bed?"

"We... can start developing from under the bed." Qin Su's ending voice raised a subtle rising tone, "I'm not in a hurry at all."
