Eight-foot gate

"Yes, there is one more day, and the asteroid will arrive. Today is the deadline for the launch of the nuclear bomb. Let's go and check the situation." Chen Wubing's tone was calm, still revealing uneasiness.

Li Haojian comforted: "Don't worry, let's go, maybe there is good news already."

Chen Wubing smiled brightly: "Yes, maybe Mr. Jin and Mr. Wang are ready for the launch, let's go and see."

The three of Li Haojian walked towards the command hall. Along the way, they ran into Zhao Hailong and others who had just woken up. Zhao Hailong was very puzzled why the Russian military base suddenly raised its defense level. Huang Manyun gave a brief Explained, Zhao Hailong was surprised, first he regretted that he and other soldiers were drunk at such a special moment, and then wondered why this Russian military base was so uneven, monsters would appear, originally thought it would be very safe here right.Fortunately, there were no Huaxia casualties, otherwise Zhao Hailong would have to wipe his neck.

Li Haojian naturally saw the guilt in Zhao Hailong's heart, and comforted him: "Squad Leader Zhao, no one would have imagined that there are so many moths in this impenetrable Russian military base. Maybe it's a good thing, we will definitely be able to blow up the asteroid."

"What's the relationship between monsters in the Russian military base and blowing up asteroids?" Zhao Hailong was puzzled.

Li Haojian laughed loudly: "The secret must not be revealed."

Zhao Hailong looked at Chen Wubing, and Chen Wubing shrugged. Zhao Hailong could only think that the Huaqing Astronomy Group had its own calculation method, although he didn't understand it very well, it was just that he was not knowledgeable enough.

The soldiers went to have breakfast, and the three of Li Haojian arrived at the command hall. There were more armed guards here, even two heavy machine guns at the entrance, and ten snipers with nutcracker sniper rifles scattered in the hall.

"Damn it, if I met the well-prepared Russian army last night, I'm afraid I will have to confess my old bones." Li Haojian broke into a cold sweat.

As soon as Chen Wubing entered the room, he looked at the various data on the main screen. Li Haojian saw that the light spot representing the asteroid was very close to the blue dot representing the earth, so the blue dot expanded a lot on the screen. Outline of the Earth.

Jin Feng, Wang Xian, and Sun Leiying were staring at the screen with several Russian experts, exchanging opinions, their faces were solemn, but their worried expressions faded a lot.

Huang Manyun still sat in the last row, and smiled at Li Haojian and Chen Wubing: "I'll wait for you here, if you need anything, feel free to call me."

Li Haojian and Chen Wubing said hello, and walked to Sun Leiying. Sun Leiying saw that Li Haojian and Chen Wubing had arrived together, and smiled knowingly: "How are you resting? Haojian, you look very energetic, you shouldn't be."

Li Haojian didn't understand what Sun Leiying said at all, and smiled lightly: "Director Sun, have you determined the trajectory of the asteroid?"

Sun Leiying replied: "Yes, it is confirmed. Now we are waiting for Mr. Jin, Mr. Wang and the experts to determine the launch plan. It is very hopeful that the interception will be completed at a distance of 1000 kilometers from the earth. If the interception is accurate, five nuclear bombs with a yield of [-] million tons will be released." There is nothing wrong with blowing up the asteroid, and even if the remaining fragments reach the earth, they will be consumed by the atmosphere," Sun Leiying said here with a smile: "Old Jin, Old Wang, am I right?"

Jin Feng chuckled: "Lei Ying, you are an expert in this field. When the rocket leaves the earth's atmosphere, it will look like a small meteorite to you. What we need to do is to make the rocket follow Lei Ying's instructions. The calculated results cannot have the slightest deviation."

Sun Leiying gave a rare introverted smile: "Old Jin, this is thanks to the great help of Russian experts, as well as the experts from the domestic supercomputer research institute. Otherwise, Wu Bing and I would not be able to calculate the accurate trajectory."

Jin Feng nodded, and said earnestly: "Yes, this is really thanks to the support of the powerful motherland, who can make accurate calculations in such a short period of time, hehe, I also want to thank the Russian army for their strong support. , providing suitable nuclear weapons.”

Seeing Jin Feng and Wang Xian smiling slyly at the same time, Li Haojian secretly wondered how to let the Russian army release nuclear weapons. Is this a very revealing thing?The old man seemed to be smiling happily.

How did Li Haojian know that the two old men took the opportunity to check the Russian army's nuclear weapons deployment, and the nuclear weapons are not Chinese cabbages, they are there, and of course they don't feel bad about using other people's weapons.As for rocket technology, on behalf of the country, the two old men took the attitude of being sure to help their brothers, and told the Russian side that there is no need to prepare anything. Of course, there is no need for technical personnel to participate. Let all Russian technical personnel who are involved All step aside.

Li Haojian searched for the extremely scarce astronomical knowledge in his stomach, and asked Chen Wubing: "Is it possible that the launch angle is too close to hit the asteroid?"

Chen Wubing nodded: "Of course, and this mission is to launch five rockets at the same time, so the probability of mistakes is higher, and there must be no mistakes. After the nuclear bomb enters space, there is still a chance to adjust the direction, but there are not many opportunities. , and not necessarily successful."

Li Haojian looked at the two light spots representing the asteroid and the earth on the main screen, full of symbolic meaning, because although the asteroid has a diameter of more than 20 kilometers, its size is not worth mentioning compared to the earth, if it is displayed in equal proportions On the screen, the asteroid may be only a few pixels in size, which is difficult to distinguish, but on a cosmic scale, a distance of 20 kilometers is like the distance from the North Fifth Ring Road to the North Fourth Ring Road in Beijing compared to the length of the equator. Small and small, there is a slight difference. It only takes a few hours for an asteroid to hit the earth. On the other hand, to hit a target with a diameter of only more than [-] kilometers within a range of [-] kilometers, the requirements for a rocket are like lettering on a hair. In general, it needs to be extremely precise.

"What do we need to do now?" Li Haojian asked.

Sun Leiying scratched her head: "Russia's nuclear bomb has passed our inspection and is being equipped. We just need to wait for the country to be ready for launch. What we have to do now is to keep an eye on the data to see if there is any change, and make adjustments at any time."

Wang Xian looked Li Haojian up and down: "This little friend, I haven't seen you in the past two days, it seems that something has changed."

Li Haojian touched his face: "Haha, Mr. Wang, is it because I made a mask that it looks supple."

Wang Xian was taken aback, never expecting Li Haojian to answer like this, then he shook his head and smiled: "Yes, yes, it seems that I should also make a mask."

Chen Wubing wanted to strangle Li Haojian to death. This answer was too cheap, and it was simply discrediting the Huaqing team!Kicking Li Haojian secretly, Li Haojian pretended nothing happened.

Jin Feng knew his old friend very well. Hearing what Wang Xian said, he couldn't help but also looked at Li Haojian carefully, but he didn't see anything. He only felt that Li Haojian's skin seemed fairer than the previous two days. Looking at Wang Xian: "Old Wang, What has changed with this little friend?"

Wang Xian smiled: "Didn't you hear from my little friend that he put on a mask?"

Jin Feng was at a loss. Although Wang Xian was not rigid at ordinary times, he never took the initiative to joke or tell jokes. Why did he act uncharacteristically today?If it was in the past, Mr. Wang must be explaining his problem just now in a serious manner.

Wang Xian saw Jin Feng's doubts and shook his head: "Not sure."

Jin Feng understood, slightly moved, then looked at Li Haojian, nodded meaningfully, Li Haojian didn't understand why.

At this time, somewhere in the northwest of Huaxia, there were crowds of people, two rockets stood upright, and the staff were doing their work quickly and silently, rushing for urgent orders.

Somewhere in the Midwest, the same two rockets, and somewhere in the Southwest, one rocket.

Five rockets.

Not far from these rockets, five Russian An-5 heavy transport aircraft can be seen.

Although separated by thousands of miles, the preparations for the five rockets are going hand in hand as if they were in a launch site.

Li Haojian didn't go anywhere all day, just sitting in the command hall, chatting with Huang Manyun and Zhao Hailong in the back row, watching the personnel of Huaqing Astronomy Team and Tianmao Group constantly update the data and return the data to the computing center .

On the main screen, the distance between the light point representing the asteroid and the blue figure representing the earth has not changed, but the blue figure is getting bigger and the outline of the surface is gradually becoming clearer.

In space, the nearly round asteroid is approaching the earth at a speed of 65 times the speed of sound.

Time passed by minute by minute.

"Squad leader Zhao, you are a soldier, how long will it take for our rocket to hit the asteroid?" Li Haojian asked.

Zhao Hailong said: "I'm not sure about this. The speed of the asteroid this time is expected to exceed 65 times the speed of sound. As far as I know, the fastest intercontinental missile is Mach 27, which is almost 27 times the speed of sound. The speed of the rocket may be faster. "

Huang Manyun interjected: "Yes, our rocket has a speed of at least 33 times the speed of sound after leaving the earth's gravity, and even faster after entering space. If it continues to accelerate, it should also be able to reach 65 times the speed of sound."

Li Haojian thought for a while: "I calculated, 65 times the speed of sound, that is about 8 kilometers per hour, if the rocket is also 65 times the speed of sound, then the relative speed is 16 kilometers per hour. Damn, 10 kilometers, less than 40 minutes Ah! Squad leader Zhao, is our nuclear bomb a bomb? It just needs to hit an asteroid?"

Zhao Hailong said: "I don't know about this, it needs professional calculations. But the nuclear bomb is so powerful, just hit it directly."

"That's not acceptable." Wang Xian walked over with his hands behind his back.

Li Haojian whispered into Huang Manyun's ear, "This old man has such good ears? Was he an underground worker before?"

Huang Manyun chuckled, and said in a low voice: "Don't talk nonsense, let the old man hear it."

Wang Xian chuckled: "I admire underground workers, but unfortunately I am not. I have been engaged in scientific research all my life."

Li Haojian had no choice but to be listened to by Wang Xian.Wang Xian had already come to the front, and Li Haojian and the others got up to give up their seats. Wang Xian sat on Zhao Hailong's seat and said, "Hai Long, after our calculations, if a nuclear bomb directly hits an asteroid, it can destroy a large area of ​​the asteroid, but it will make the The asteroid left a huge metallic core, more than fifteen kilometers in diameter, which is still not what humans can bear."
