"Sister, let go of me, I'll tell you." Hao Jie pushed Mu Xiaoling away hard, in fact, with Mu Xiaoling's strength, Hao Jie said that she would overturn it, but he didn't want to do it. He just struggled a little and pushed Mu Xiaoling away, after all, Mu Xiaoling also felt that it was not very comfortable to press a big boy like this.

"Look me in the eye and don't lie." Mu Xiaoling shouted.

"Actually, it's nothing, it's just that a friend of mine lives next door, and I feel very lucky, so I'm happy. As for choosing this room, the reason is very simple, that is, you can sit in the bay window and chat with friends. Hao Jie told the truth, in fact, there is nothing to hide, and when he sees Ziyan, everything will be revealed, and there is no need to hide it now.

"Friend, you've only been in Shanghai for a few days?" Mu Xiaoling asked rhetorically, and then asked in a disdainful tone: "Looking at your spring heart-rippling expression, your friend next door should be a woman, right?" ”

"What's wrong with the woman? Am I not allowed to know a girl? Looking at Mu Xiaoling's expression, Hao Jie was very unhappy. Although Sister Papaya is very beautiful, with her temper and her cold face, she is probably still an old aunt. Who told you to pretend to be forced all day long, you deserve to be so old and still an old virgin.

"Is it the girl who hit you on the left cheek, or the girl who hit you on the right cheek?" Mu Xiaoling asked disdainfully, there was still a bit of ridicule in her words, as if she was saying, you still want to refute when you say that you are cheap, people beat you, and you still stick it on people, so look for it, such a cheap man is really hard to find.

"What hit the left cheek and hit the right cheek, I don't understand what you mean. This friend of mine is gentle, beautiful and gentle, and can cook noodles and make dumplings. Speaking of Ziyan, Hao Jie suddenly remembered the warm picture of the night before yesterday in his mind, and he couldn't help but swallow his saliva.

"And a woman? You're really attentive, you've only been here for three days, and you've known three girls. Mu Xiaoling despised Hao Jie more and more, what she hated in her life was those prodigal sons and big turnips, if she was allowed, she wouldn't mind castrating all these flowery ghosts.

But now she's on a mission, so even if she hates this man anymore, she won't be fine. However, in order to avoid being impulsive one day, necessary reminders are still necessary. She took out a pistol and put it against Hao Jie's head, and said sharply: "Boy, you have heard me clearly, any girl you talk to and date in the future must report to me, and I must be present, and I must get my consent to make new friends, otherwise I will shoot you in the blood." With that, she put the gun against Hao Jie's lower abdomen.

"Sister, if you have something to say, you have something to say, hurry up and put the gun away, so as not to go off." Hao Jie suddenly broke out in a cold sweat, what is this.

"Coward, I didn't open the insurance." Mu Xiaoling said disdainfully, I don't have the courage, how can I send me to protect this coward, it's really a waste of time.

"Sister, you are my own sister, can you put the gun away? You must know that there are wars everywhere now, and the production of military factories is particularly urgent, and the quality inspection is certainly not as strict as before, maybe there are many guns that are shipped without inspection, and maybe this one in your hand is a substandard product. You think you'll be fine if you turn off your insurance? Maybe the safety of this gun is bad at all, safety first, sister. Mu Xiaoling never took the gun back, Hao Jie was in a hurry, so he reasoned with her.

Mu Xiaoling really put the gun back and inserted it back into the gun box, but it wasn't because she listened to Hao Jie's persuasion, but she really couldn't stand it, "What are you talking about?" A lot, inexplicable, look at your age, how do you look like a pedantic old showman. ”

Dare to doubt my arguments, can be killed but not humiliated, Hao Jie pulled Mu Xiaoling to the living room, and said: "Sit down, I have to explain to you well, this is science is not pedantic, do you understand?" ”

"I don't know, I'm going to clean up the house." Mu Xiaoling was not interested in listening to a poor sour show before losing her schoolbag, so she was about to get up and go back to the house.

Hao Jie pressed Mu Xiaoling and said: "It doesn't matter if people don't understand, the key is to be studious, if you don't understand and don't learn, that's ignorance, why can't China defeat the imperialist powers, and now it can't even beat a little Japan, it's your kind of thinking that harms." ”

Mu Xiaoling obviously didn't have much patience, but her task was to protect Hao Jie, and she had nothing else to do, and she was quite bored watching it twenty-four hours a day, so she simply sat down and listened to how this Xiucai who had drunk foreign ink behaved.

Seeing Mu Xiaoling sit down, Hao Jie began to explain endlessly: "This pistol is composed of several parts, right?" Each component is made up of several processes, right? People do all this work, right? ”

"That's no nonsense!" Mu Xiaoling nodded at first, but when she heard Hao Jie say that she was so mentally retarded, she couldn't help but be a little speechless.

Hao Jie ignored Mu Xiaoling and continued: "Since they are human, then everyone has a nap, right? If the worker who made the gun took a nap while making a part, would the gun be defective? So if the insurance is made when the worker dozes off, then is it possible that the insurance is bad, and if the insurance is bad, then the insurance will not work? ”

"It seems to make some sense, but if the insurance is broken, this gun can't leave the factory?" Mu Xiaoling nodded, and then asked rhetorically.

"Now that the whole world is at war, isn't the business of this military factory very good? Isn't there a lot of military factories? Are all the troops waiting for the military factory to ship? Hao Jie continued to ask inductively.

Mu Xiaoling nodded again and again.

"It's too late for military factories to produce, so how many military factories still implement strict inspection processes, and even if they do, it's just a sloppy matter." Hao Jie continued.

"The troops have inspected the goods when they receive them, and if the guns are not qualified, they will definitely return them to the arsenal?" Mu Xiaoling asked suspiciously.

"That's a good question. So I would like to ask you, when the troops receive the goods, all the functions of each gun are tested? Since only a few guns were sampled, how could we draw the bad guns that the workers made when they were dozing? Taking a step back, even if all the guns were tested by the troop procurement department, then how many people would be needed for this, and who could guarantee that these people would not doze off? Hao Jie explained.

"There is some truth in what you said, it seems that I must check and inspect the gun when I get it in the future to avoid misfire." Mu Xiaoling nodded.

"Remember that when you test, you can't come up and try to shoot." Hao Jie added.

"Why? Since it's a firearm, being able to shoot accurately is the most critical function, right? As for insurance, it's just for you. After saying this, Mu Xiaoling smiled and looked at Hao Jie's lower abdomen.

Hao Jie intuitively felt that his hairs stood on end, this papaya sister is too terrifying, why do you always worry about castrating me. However, this guy has well-developed limbs and a simple mind, and since he has lectured her, he simply understands it. So Hao Jie continued: "In addition to the basic function of being able to shoot, the pistol also has another important safety function, that is, exploding. If the barrel is not made of good material, the melting is defective, or there are air holes, cracks, or the size of the muzzle is smaller than the size of the bullet, the phenomenon of exploding may occur. If you get a shoddy pistol with a blast, when you shoot, the pistol will blow up your hand, or if the splinters hit a vital part of your body, it could kill you directly. ”

When Hao Jie said this, Mu Xiaoling couldn't help but break out in a cold sweat, she really didn't pay attention to this kind of problem before, but she really heard that some soldiers were killed by their own guns, everyone used to say that the person's life was not good, but they never thought that it was all the fault of the military factory. However, Mu Xiaoling was unwilling to lose to Hao Jie, "You said that you are so hanging, there are not many accidents like this." ”

Hao Jie thought to himself that you wouldn't shed tears when you didn't see the coffin, so he asked rhetorically: "Do you think that the success rate of your every action is 90% high?" ”

"I'll do it 90 percent, but I'll try to get to 99 percent." Mu Xiaoling replied affirmatively.

"Well, even if you have a 99% success rate every time, that's high, right? For example, a pistol has five key parts, and the pass rate of each part is 99%, so what is the pass rate of the finished gun? Hao Jie asked inducedly.

"Ninety-nine percent multiplied five times in a row, and the result is ninety-five percent of the way." As an agent, Mu Xiaoling's arithmetic ability is very strong, otherwise it would be impossible to calculate the effect of wind speed on bullets in a very short time.

"Yes, it's a quick calculation, ninety-five percent, which means that five out of a hundred guns are broken, and one out of twenty guns is broken. With such a high defective rate, can you still be sure that your gun is good? Hao Jie asked rhetorically.

"But my colleagues and I have used so many guns and found nothing wrong, you are sophistry." Mu Xiaoling was startled at first, and then thought about it carefully and felt that something was wrong.

"Hehe, that's because the gun you used before the military factory has been inspected before it leaves the factory. However, inspectors will also have negligence, a large number of data statistics, the qualification of human behavior conforms to the normal distribution, the probability of human negligence is 99 percent of 73, which shows that every 1,000 regular factories formally inspect the factory of firearms, there are three may be defective products. 3 out of 1,000, have you ever used 1,000 guns with a colleague you know? It's just that those three problematic guns didn't get into your hands. And now the military factories are even more chaotic, so the defective products are now far more than three thousandths. Hao Jie continued to explain.

Mu Xiaoling nodded while listening, it seemed that her posture had risen now, and she couldn't imagine that there were two brushes for this coward.
