Annihilation of the solar system

Zhou Cheng's settlement is on the first floor of the National Police Building. It used to be a conference room and was quite spacious. Now it is divided into two rooms, with a bedroom inside and Zhou Cheng's big blackboard and desk outside. At the bottom of the building

It is a large-scale three-story underground civil air defense garage, and below it is the National Security Secret Service.

The setting sun shone in through the window, illuminating the room very brightly. Zhou Cheng was very satisfied with this environment. After industrial production stopped, the vast majority of the population moved to cities. This was essential for turning cities into fortresses.

It is important and makes cities more crowded than ever.

The location where he lives does not have to be as cramped as people in the subway, nor does he need to be as nervous as people living in high-rise buildings. If there is an emergency, he can go down to the underground garage civil air defense project in the shortest possible time.

If necessary, he can hide in the secret service station further down. For a top physicist like him, this is all preferential treatment.

Zhou Cheng drew another standard pentagon in the center of the blackboard, and was about to write data into one of the top corners when suddenly a shrill air-raid siren sounded outside. He immediately threw away the chalk in his hand and turned from the door.

Take off the helmet from the rack and put it on, then put on the armed belt.

While putting on the equipment, he listened carefully to the air-raid sirens that resounded throughout the city. The sound gradually changed from deep to sharp, then rushed to a harsh high-pitched sound. It lasted for a few seconds and then dropped again, and so on.

. He knew that this was a danger warning, not a combat warning.

After putting on his clothes, Zhou Cheng ran toward the stairs with his rifle. Along the way, more and more people gathered on the stairs. Everyone was dressed appropriately and ran down the stairs in an orderly manner. He followed the instructions

During the usual training, the route of the danger avoidance alarm came to the third floor of the underground garage. Cao Rui was already waiting for him here. Soon, his wife Shen Manling also came here.

"Old Cao, is this a drill?" Zhou Cheng asked.

"No, let's talk about it downstairs." Cao Rui took them down to the Secret Service Bureau in the elevator.

The layout of the Secret Service is also very different from before. A small half of the space here has been transformed into a preparation command center. Cao Rui took Zhou Cheng and Shen Manling to a row of screens, operation desks and various instruments.

Shen Manling immediately recognized the image displayed on the screen and said:

"We were just studying this latest situation when the combat command center issued an early warning."

"What's going on?" Zhou Cheng was doing research in his room, naturally he didn't know what happened.

"A large ice block about ten kilometers long has emerged from the broken ice belt and is accelerating towards the earth!" Cao Rui said while looking at the ice blocks reflecting the colorful light on the screen.

"It was discovered yesterday. Although judging from its current orbit, it will not directly hit the earth. However, no one can tell whether it will change its orbit." Shen Manling said.

Cao Rui had a sly smile on his face:

"What my sister-in-law is saying is that if it hits Jinghua directly, there is a high probability that it will be useless if we hide here. Now the evacuation alert has been sounded all over the world, and everyone has hid underground. It depends on its next move.

, no one knows what it’s going to do.”

A trace of panic flashed across Zhou Cheng's face:

"No other measures were taken?"

Cao Rui looked calm:

"I heard that that thing is about to enter the effective range of the space turret, and the space force is already preparing to intercept it."

Shen Manling said:

"Xia Lan also went to the combat command center as an expert consultant to provide support. The speed of this big ice block is slower than 'Oumuamua, so we have more time to react. The size is also much larger than 'Oumuamua, making it easier to detect. Basically. It is mainly composed of water ice, so it should be much easier to intercept."

"I hope so!" Cao Rui's words were full of helplessness.

In the server cabin of the "Zhenyuan" space turret, Ke Guohao is checking whether the plug wires and fuses on the server are secure. This is the third time he has checked, and other members of his team are also doing this in other parts of the space turret. Doing the same thing.

Even he himself knew that it was unlikely that there would be any problems with the inspection, but he still had to do it because the "Zhenyuan" was about to begin its first battle with an alien civilization, which made his hands and feet tremble with nervousness whenever he had nothing to do. More importantly, Yes, he didn't want anything to go wrong in the maintenance of the electronic equipment under his control during the battle.

He closed the door of a server cabinet and was about to open the door of the next cabinet. Suddenly, the police light on the ceiling flashed, followed by a short and harsh siren. The battle alarm sounded!

Ke Guohao immediately put on a mask, because the interior of the space turret will be evacuated to the same vacuum as in space 5 minutes after the alarm sounds. This is to avoid cracks in the sealed cabin causing explosive decompression, which would destroy the cracks that were originally easily repaired. It becomes an irreparable hole.

All the soldiers in the narrow corridor ran to their combat positions in an orderly manner. The space turret was very large, but 1/3 of its weight was armor, 1/3 of its weight was ammunition and supplies, and the other 1/3 was Sealed cabin.

When the soldiers are running, their bodies will tilt uniformly from time to time, and then return to upright. It looks like a row of tumblers on a seesaw. This is the attitude adjustment engine of the space turret adjusting the orbital position of the turret.

Ke Guohao came to the bridge next to the three electromagnetic orbital main guns on the top of the space turret. Although the space turret did not have interplanetary navigation capabilities, both the personnel programming and the equipment composition were set up according to naval ships. People just It is customary to refer to her as a naval ship.

As the leader of the electronic equipment system maintenance team, he needs to be on the bridge during battle. He stood at his position, with a screen in front of him showing the operating status of the entire ship's electronic equipment. In addition, every There are stainless steel handrails in front of each operating table.

He looked through the entire bridge to the porthole on the right side. There were three electromagnetic railguns with a track length of 35 meters. Under the protection of his thick armor, they were slowly turning to the side. Outside the porthole on the left, another A space turret like theirs, the "Dingyuan," was adjusting its attitude.

The structure of the space turret is very simple. It is a flattened diamond shape when viewed from any direction. Four inclined surfaces form the outer structural surface of the space turret, which is a composite armor that can resist the firing of its own main gun. The turret On the top, where two large surfaces meet, there are three electromagnetic rail turrets in the middle, and on one side is a slightly raised square bridge with large portholes.

"Dingyuan" and "Zhenyuan" have completed attitude adjustments, and their sides are now facing the direction of attack. The thick sloped armor can ensure that they can withstand the collision of any object at the speed of the second universe, and all the electromagnetic waves are turned to complete

A railgun could easily destroy a mountain on Mars.

"Prepare to fight!" the captain standing in the center of the bridge gave the order.

(May we live forever and share the beauty of the moon thousands of miles apart. I wish all my friends a happy Mid-Autumn Festival. When we look up at the moon together, we can see each other.)
