During World War II, country M dropped a little boy and a fat man on the island, which were two atomic bombs designed to yield about 20,000 tons. The radius of destruction reached two kilometers, and the radiation contamination was terrifying. This was the only time that mankind used a nuclear bomb in a war, when the atomic bomb exploded more than 600 meters above the ground, in order to increase the radius of destruction, if the explosion height is reduced, the explosion power can be concentrated, and the radiation range can be reduced.

The neutron bomb mentioned by Du Fei, also known as the "enhanced radiation bomb", is a kind of small hydrogen bomb developed on the basis of the hydrogen bomb, with high-energy neutron radiation as the main lethality, and the power is 1,000 tons. It belongs to the third generation of nuclear weapons. The first and second generations were the atomic bomb and the hydrogen bomb, respectively.

Neutron bombs are characterized by large nuclear radiation effects and strong penetrating power when exploding, and the energy released is not high, and the shock wave, optical radiation, thermal radiation and radioactive contamination are smaller than those of ordinary nuclear weapons.

The killing principle of neutron bombs is to use the strong penetration of neutrons. Among the many nuclear weapons, the neutron bomb is not the most powerful in terms of overall power, or even the weakest. However, the nuclear contamination of the neutron bomb is the smallest, except for the fourth-generation non-polluting nuclear bomb being studied, the neutron bomb is the cleanest of the nuclear weapons that can be used at this stage, which is why Du Fei proposed the neutron bomb.

The 51st Military Region has neutron bombs, and the latest Shenguang technology is also shared by the 51st Military Region with other military regions, so Du Fei is sure that the 51st Military Region has available neutron bombs.

Du Fei guessed that if this corrupt giant tree had also appeared in its previous life, it would probably have been destroyed by nuclear weapons. Among the many nuclear weapons, the nuclear contamination of three-phase bombs and hydrogen bombs is too serious, and if the yield is too large, it is likely to affect the base city, and the only thing is that the neutron bomb is relatively clean.

But it's a pity that the physical destruction ability of the neutron bomb is somewhat insufficient, and the destruction radius is only two hundred meters, so if you want to use a neutron bomb to deal with the second stage of the corrupted giant tree, I'm afraid it's a bit hanging. It needs to be used with other small tactical nuclear bombs or high-explosive bombs, but these are not what Du Fei needs to care about, if the military region can't even think of this, then there will be ghosts.

Du Fei said everything he could say, and did everything he could do, and the rest was the affairs of the military region.

Out of the military headquarters, Du Fei saw Ouyang Xiu sitting on a plane tree from a distance.

As soon as Du Fei got closer, Ouyang Xiu whistled at Du Fei like a female hooligan, and then said, "Hey, handsome guy, have you finally finished teaching people to shoot guns?" ”

When Du Fei heard this, he almost choked to death with his own saliva, and he didn't dare to answer her words, but said, "What are you looking for me for?" Didn't get caught by your brother? ”

"My mother already knew that you were going to betray me, so I came back last night and slept with someone you wanted to cuddle with. Besides, I'm not here to wait for you, I'm here with someone. Ouyang Xiu stood up on the tree and said.

Then, Qin Xiaoyuan walked out from behind the tree, a little twisted, probably because of the sequelae of last night.

Du Fei guessed when he saw Qin Xiaoyuan that Ouyang Xiu must have jumped out of his window last night and then turned back to Qin Xiaoyuan's room for the night. Qin Xiaoyuan has a gentle temperament, she doesn't like to reject people very much, as long as others treat her well, she will also treat others well. Especially like Ouyang Xiu, who is self-acquainted, and has only known each other for a day, he can almost develop a super friendship relationship.

"Is something wrong?" Du Fei stepped forward and asked.

"Nothing serious. It's just that my uncle is looking for you everywhere, it seems to have something to do with some medicine, and I don't know. Brother, go back quickly. Qin Xiaoyuan said.

"yes, I see. Go back now. Du Fei said and took the lead in walking back.

Qin Xiaoyuan followed beside him in no hurry, but always took a step slowly. Before going to college, the two kept this distance and pace, Du Fei stopped, she stopped, Du Fei took a step, she took a step. The two walked in a straight line at this pace for more than ten years, four times a day, or even six times, and the cycle had long since become a habit.

Qin Xiaoyuan is too quiet, her voice is very good, but she doesn't like to talk much, and she always thinks more than she says. Du Fei didn't know what she was thinking about all day long, but she had long been used to it, anyway, whatever Du Fei said was what she wanted, and Qin Xiaoyuan never objected. Even most of Du Fei's summer vacation homework in the past was done by Qin Xiaoyuan, because Du Fei always delayed his summer vacation homework until the last day.

Ouyang Xiu jumped down from the tree with a somersault, grabbed Du Fei's arm with one hand, tiptoed into Du Fei's ear and whispered, "I didn't expect that you were also pure." ”

Du Fei glanced at Qin Xiaoyuan next to him, and wanted to pull his hand out of Ouyang Xiu's claws, but Ouyang Xiu was just sticking to his face.

"Last night, Sister Xiao Yuan told me about your childhood, Sister Xiao Yuan is so kind, it is estimated that she will help you count the money if she is sold by you. So I decided, I must let Sister Xiao Yuan recognize your animal nature. Ouyang Xiu continued to whisper.

Qin Xiaoyuan walked with her head down, frowning slightly, obviously hearing Ouyang Xiu muttering there. Seeing that he couldn't shake off Ouyang Xiu's dog skin plaster, Du Fei slowed down for half a beat, then reached out to hold Qin Xiaoyuan's hand, and held hands to bring her closer.

At this time, Ouyang Xiu was suddenly startled, stopped and grabbed Du Fei, pulled him to the path, and hurriedly said, "Go this way, hurry up, go this way." ”

Du Fei ignored her, and the three of them pulled and pulled until a loud shout sounded: "Little Xiuzi! ”

Du Fei looked for prestige, and saw Ouyang Lingfeng blocking the middle of the road with an angry face. Ouyang Xiu walked out from behind Du Fei at this time, stood up straight and waved his hand to greet him: "Big brother, are you also there?" We still have to go beforehand. ”

Ouyang Lingfeng saw the three of them pulling and pulling, so he glared at Du Fei angrily.

Du Fei had never offended him, so he naturally glared back.

"What are you doing here?" Ouyang Lingfeng looked directly at Du Fei and asked, he looked at the hand held by Du Fei and Qin Xiaoyuan, and then looked at Ouyang Xiu holding Du Fei's hand, the little good impression he had for Du Fei before was gone.

"Go home." Du Fei replied as a matter of course.

Ouyang Lingfeng looked down at Du Fei's hand held by Ouyang Xiu and asked, "Then what are you doing?" ”

Du Fei raised his hand, opened his five fingers and shook it, and replied, "I didn't do anything." ”

Ouyang Lingfeng moved his gaze to Ouyang Xiu and said in a stern tone, "Go back with me." ”

"No......" Ouyang Xiu said, then hugged Du Fei's hand tighter and continued, "If you want to go back, you will also go back to your new home." ”

"Where are you going to find a new home, and then I'll see how I fix you." Ouyang Lingfeng said.

"I'm already his man." Ouyang Xiu said to Du Feinu.

Du Fei, Qin Xiaoyuan, and Ouyang Lingfeng looked at Ouyang Xiu with wide eyes at the same time.

"Damn, when did I have such a person as you?" Du Fei saw that Ouyang Lingfeng's eyes were about to erupt into flames, and he wanted to clarify.

"Have you forgotten? On the dark and windy night of that month, we were all over the place, **, you said you were not used to it......" Ouyang Xiu said with a lot of care.

"I'll go, you're going to make a movie?" Du Fei was really speechless, shook off Ouyang Xiu's hand vigorously, and then shrugged his shoulders and said to Ouyang Lingfeng, "Do you believe it?" ”

Ouyang Lingfeng's eyes were on fire, it was estimated that he had been blown up, and he gritted his teeth and said, "I want to duel with you, you decide the time and place." ”

Du Fei didn't expect Ouyang Xiu to play with fire like this, but it didn't matter, Ouyang Xiu couldn't let her eldest brother come to duel, this fight couldn't be fought.

Watching Ouyang Lingfeng drag Ouyang Xiu away, Qin Xiaoyuan asked with some worry, "She'll be fine, right?" ”

"At most, I will be taught a lesson, I think she has long been used to it, don't worry about her, let's go home first." Du Fei said, naturally taking Qin Xiaoyuan's hand and walking back.

After arriving home, before Du Fei had time to catch his breath, Du Qihuang jumped up and grabbed Du Fei's shoulder and said excitedly: "Is there any vaccine medicine?" Tell me about it, but is there any? ”

"There should still be. Dad, why are you so excited? Du Fei replied inexplicably.

"That kind of medicine can save your grandfather, I have studied medicine for so many years, and I know too much about the properties of medicine, this medicine will definitely save your grandfather." Quick, give me another one. Du Qihuang said anxiously.

Du Fei didn't expect his father to say this, Du Long's old guy can last for two days at most, the virus stock type C does have some effect on it, but it may not be able to save it, Du Long's legs are already rotten, even if he survives, he can't stand up, so Du Fei has always avoided this question, because his heart is also very messy. But now his father has discovered the effect of this potion, and he has put this choice in front of Du Fei.

"Dad, don't get excited. That kind of potion doesn't have much effect on the old guy, so forget it. Du Fei has always had a kind of resistance to this titular grandfather.

"No, Xiaofei, you must save your grandfather. Dad knows you hate your grandfather, but that's something you don't know a lot to think so. Du Qihuang said hurriedly.

"Dad, our family doesn't have to get involved with those people and is doing well, just as they don't exist, isn't it good for our family to live happily?" Du Fei tried his best to appease his father.

"That's not the case, Xiaofei, I must tell you everything today." Du Qihuang took out an antique Nokia mobile phone and continued, "There is a number in this that was given to me by your grandfather, and your grandfather has always carried the mobile phone with this number, and there is only one number on the mobile phone, which only exists for our family." ”

"Your grandfather has always cared about us, I have worked in Dulong Pharmaceuticals for thirty years, although I have not been promoted, but I have participated in the research of almost all precious drugs, I like this job, so I can do it for thirty years."

"Xiaofei, in order not to affect your life, your grandfather doesn't want that family to harass you and let you grow up like an ordinary person, so he won't intervene in our lives. This is an agreement between him and the chairman's wife. ”

"Also, when you were in junior high school, you kicked a hooligan. You run home and say you're scared something is going to happen, but then nothing happens. In fact, that hooligan called dozens of people to block you at the school gate, and it was your grandfather who called to have them arrested. ”
