Defend Namsan Park

In the history of human science and technology, there has never been a weapon that can deal with the moving speed of Mach 23 in the atmosphere. This speed even exceeds the warhead of the strategic intercontinental missile when re-entering the atmosphere. If the sword angel really moves on the surface at the first cosmic speed, then Humans probably have nothing to do with it. Chen Yu had a bad premonition in his heart. After taking samples and taking pictures, they returned overnight, drove wildly on the dark road, and drove smoothly into the ditch beside the road .

The four of them had no choice but to go down to repair the car. At this time, it was completely dark, and it was wet and cold outside. They were in the wilderness, 151 kilometers away from [-]. The communication was cut off, and the phone could not be reached. Chen Yu leaned on the car door and shook hands. Electricity, dangling to the dark bushes in the distance.

"Is the chassis okay?"

"No problem... just rubbing it for a while, I don't think it's a big problem." A staff officer of the intelligence department got up and patted the dirt on his body, then turned his head and asked, "How much natural gas is left?"

"Enough for us to drive back."

Chen Yu turned the brightness of the flashlight to the maximum, and the bright beam pierced the darkness like a sword.

Strictly speaking, except for the Sichuan Basin, the whole world is an uninhabited wilderness. Since Seraphim came to the earth, the living space of human beings has been compressed to 1% of its original size. After that, except for Sichuan, everything is an abyss.

Chen Yu has always had this kind of imagination: No one can tell what kind of changes the angels have brought to the earth. What if it is not only angels who appear in this world?

"Have you ever heard of a famous American urban legend called the Mothman?" Chen Yu asked.

"I have heard that the mothman is said to herald disaster, bad luck and death, and the unlucky one who meets the mothman will not end well." Someone knows this allusion, "Why, tell me, you saw the mothman Is it?"

"I'm not sure if that's the Mothman, but it's on the way we came, behind the black bushes, a dark shadow, five or six stories high, with one leg straddling the road, one leg On the other side of the road, there is a very long neck, like a snake." Chen Yu stared at the road when he came, "It has four red eyes and a mouthful of white teeth. smiling at us."

Everyone turned their heads in horror, and looked in the direction of Chen Yu's flashlight beam, only to see that there was a thin mist in the dark and turbid air, and there was nothing else.

It's hard to say whether Chen Yu really saw it or pretended to see it. Maybe he really foresaw something that night, that weird shadow—maybe it's a living thing or not. If you have to find a word to describe and describe it, The most suitable is the god of death.On that dark and wet road, on the way back after touching the traces of the sword angel, Chen Yu felt that he had foreseen someone's death.

The four-person team finally stumbled back to 01 at 30:151 in the morning. The four were so tired that they were about to fall apart, but they had no time to rest, and were immediately pulled up by the Base Command and the Joint Reference Center for a meeting.

The observation of a brand new angel is a significant event for the entire human society, which means that there is one more enemy that humans need to face, and it means that the human world is one step closer to the end.The discovery of the Knife Angel also confirmed another conjecture - like the sun and the moon, there are also satellite angels on the earth, they revolve around the earth at the first cosmic speed, hang high in the sky above the Karman line, within the orbital radius No one can spot them until they shrink enough to make contact with the surface.

The No. 093 Sword Angel may be the first satellite angel in contact with the earth's surface. It is foreseeable that since it is lowering its orbital altitude, there is no reason to stop this trend. No matter in the three-dimensional universe can stop the four-dimensional manifold, it It will fall into the center of the earth along a spiral orbit and cut the earth completely.

From this point of view, it will be the sharpest knife ever seen in human history.

This is another angel of the world-destroyer level.

"We speculated the possible trajectory of Angel 093 based on the existing traces on the surface. There are a total of 31750 situations. Of course, it is only the most preliminary guess at present. They may not be accurate. After all, we know almost nothing about it. We must accurately predict 093. The trajectory of the Angel still needs a lot of more accurate, more intuitive and more detailed data."

Thirty-one thousand, seven hundred and fifty white spirals densely surround the earth, appearing like a messy ball of wool. All eyes are focused on the monitor. Everyone knows that more than 750 predicted trajectories are meaningless.

At the joint staff meeting of the Science City, the Joint Reference Center, and the 151st Command, all the remaining experts in human society were present. It was so urgent that 151 could not even wait until the next morning to go to work. This is a 03 in the morning At the meeting held at :30, the participants were all blown out of bed by the phone.

"Is it really moving that fast?" someone asked.

"If the gravitational effect is dominant, then it should be so fast." The Science City expert on the other end of the connection replied, "The orbiting speed is the lowest speed at which the satellite angel orbits the earth, and it may even be faster."

"Is it possible for it to pass through the Sichuan Basin again?"

"If it is a celestial body, then its movement should be regular." Science City replied, "Of the more than 3 trajectories we estimated, more than 88% of the cases will pass through the Sichuan Basin at least once."

"What's the worst-case scenario in your forecast?" someone asked. "Tell me about the worst-case outcome."

The expert group of Science City looked at each other on the screen.

"In the current model, the worst outcome is that it has sunk into the Earth's lithosphere, and is now moving rapidly under our feet, lowering the orbit altitude round by round, passing through the crust and mantle, and finally falling to the center of the earth." Science City gave an answer, "The matter in the three-dimensional universe is no different from air to angels, but we have nothing to do with things that have sunk deep into the earth's crust. It can travel underground at a speed of Mach 23, and we drill a It takes a lot of effort to get a small eye one kilometer deep."

"What would happen if Angel 093 fell into the center of the Earth?"

"We're screwed before it hits the center of the Earth," Science City said. "It does have the power to slice the Earth round and round."

Most of the people present had a picture of a watermelon being cut open by a knife in their minds.

Science City realized that their thinking was wrong, and then explained: "Everyone, the earth is a huge celestial body with a mass of 60 trillion trillion tons, and its main structure is supported by gravity, which is a very stable force in the universe. Force, it is the mutual attraction and cohesion that matter naturally has, so you can’t cut the earth into two halves that are separated from each other like cutting an apple, because it will naturally gather together, in fact, cutting the earth and then Break it in half, and the latter one may not even be able to make an angel."

The atmosphere in the conference room was a little more relaxed. Many people were worried that the earth would become two hemispheres, the mantle and core would leak out like egg yolk, and the atmosphere would escape.

"But everyone, the fact that the earth won't be cut in half doesn't mean it's not deadly." Science City's tone suddenly became serious, "Don't forget that we are sitting on an earthquake belt."

The image on the demo screen was switched to a satellite image of the Eurasian continental plate, and an invisible red pen drew a circle at the location of the Sichuan Basin.

"Under our feet is the large fault structure zone formed by the extrusion of the Eurasian continental plate and the Indian Ocean plate. To our west is the Qinghai-Tibet Plateau and the Himalayas. They are the result of the Himalayan orogeny, which shows that we are at the junction of several large plates. , especially in the Zitong-Chengdu-Weiyuan-Guang'an area, there is a huge tension-torsion fracture structure in the Sinian to Lower Triassic strata, and huge stress may have accumulated inside the rock mass. past……"

The animation on the big screen went deep into the earth's crust, and the experts from the Science City vividly explained to the people present that human beings were squatting on a big powder keg.

"The result is 8.5% catastrophic. We estimate that the lowest intensity is [-] on the Richter scale. The seismic waves will radiate the entire Sichuan Basin, and nothing will be left."

There was silence again in the conference room.

Shin Kang raised his hand.

"Comrade Shin Kang, what's your question?"

The girl raised her head, pressed the toilet paper with one hand to block the nosebleed, and pointed at the screen with the other:
"I've said so much, it's all your guesses."

"Yes, just a guess based on current observations."

"Most of the guesswork results are unreliable, not to mention that no one is a real angel expert. You are not professional enough. It is too early to make a conclusion." Shen Jiang straightened up, yawned, and looked around, "093 You don’t know what the angel looks like. No matter how much you discuss it, it’s just fantasy. I suggest you go back and rest. Tomorrow, all seven high-altitude drones will be called in, and a [-]-kilometer-long line will be pulled to see what’s going on first. What is it."

151 The reconnaissance operation against Angel No. 093 was launched in full swing. The only remaining seven Yunying high-altitude reconnaissance planes and 093 aerial refueling planes in the human world took off from three bases at the same time. The [-]-kilometer-long optical and infrared detection line is guarding No. [-] Sword Angel that may pass under the nose.

No one knows when Angel 093 will pass by again, so the UAV’s stay in the air should be as long as possible. Of course, it’s better not to sink into the earth’s crust.

Facing a Tuxingsun whose moving speed exceeds Mach 23, human beings have nothing to do.

The joint reference center and the base headquarters have been busy with this matter for several days, but Shanglu, who is in the workshop system, is a bit behind the times. Chen Yu worked overtime in the combat department of the headquarters and worked on the floor for several days. The dormitory took a change of clean clothes and mentioned it to Shang Lu, and Shang Lu knew about it.

"A newly observed angel?"

Shang Lu sat on the bed with a water glass in his hand and sorted out Shen Jiang's OPM-BCI helmet adaptability test report. The MEG system training between him and Shen Jiang had come to an end, and there were still one or two classes before the end.

"Yes, it was discovered in the past two days. So far, only the traces have been caught, and the real owner has not been seen."

Chen Yu opened the drawer of the closet, his eyes jumped back and forth between the balls of socks and the folded underwear, and picked the right one to throw into the bag.

"Don't forget to bring a few more pairs of insoles to change. It's been very humid in the tunnel lately." Shanglu asked casually, "What's the size? That newly observed angel."

"I see, when did I need your chief engineer to teach me how to live, your ability to live is zero." Chen Yu said, "As for the new angel, it is No. 093."

"093?"

Shanglu's heart skipped a beat.

"Well, 093." Chen Yu nodded, "Temporarily named Sword Angel."

"Bang!" With a sound, the water glass in Shanglu's hand fell to the ground.

Chen Yu turned his head in surprise, and saw the dropped water glass overturned on the floor, and the hot water spilled all over the floor. Phytophthora's face was pale, his eyes were distracted, he stared blankly at his feet, and his hands trembled uncontrollably.
