Little Mushroom

"Emergency power is on."

"The emergency intercom channel is open."

"Emergency defense is on."

"The ventilation system is on."

"The radiation defense window has fallen."

"Please ask the departments to stand by."

In the corridor, in the cluttered footsteps and shouts, the radio was turned on. It was no longer a mechanical sound, but a human female voice.

As the sound fell, the dull "snoring" sounds continued to open in all directions. An Zhe looked towards the corridor again. The cold steel curtain wall slammed down and blocked all the windows. It looked very thick-he remembered the words of the poet. Once the magnetic field disappeared, the rays from the universe and the solar wind would immediately hit the surface of the earth. .

So he knew that Lu Yan had just dragged himself out of the corridor to leave the range where the cosmic radiation could reach-and the main city was a building of the peak of human science and technology. The thickness of the wall and the special material could prevent the attack of radiation.

The lights of the United Front Center Building turned on steadily after the mad extinction, but this time the lights were much weaker than before, showing a weak pale.

Recently, the voice of a researcher's dial-up communication came from the laboratory. He was too anxious. The voice was loud enough to be heard throughout the corridor.

"D1342 requested to increase the power supply! The instrument cannot be stopped!"

Another laboratory also heard a voice: "D1343 requests emergency power, otherwise precious samples will soon be inactivated."

Who will answer their request? Can it be fulfilled? An Zhe didn't know. He looked in the direction of D1344 and subconsciously grabbed Lu Yan's sleeve.

Lu Yan looked down at him and said, "It's all right."

An Zhe nodded.

The broadcast continued.

"Persons in charge of the Equipment Center, Urban Defense Station, Emergency Response Department, and Logistics Supply Office, please go to the first meeting room on the 17th floor of the United Front. Please do not take the elevator and use the emergency passage to go up and down."

"Please contact the Magnetic Field Observation Office of the Lighthouse immediately to the System Warfare Center."

"Please contact the Magnetic Field Observation Office of the Lighthouse immediately to the System Warfare Center."

The broadcast sound turned on to its fullest, and the reverberation echoed through the corridor.

An Zhe looked at Lu Yan: "Are we back to the lighthouse?"

"I'll wait for the order," Lu said, looking at the bridge, as if thinking about something, and turned back to An Zhe: "Don't run around, follow me."

An Zhe said, "OK."

Just listen to the radio and said: "Please ask the person in charge of the command office, joint staff, trial court, and operation center to go to the communication center on the 14th floor of the United Front. Please do not take the elevator and use the emergency passage to go up and down.

As soon as he entered the gate of the communications center, Anzhe heard the voice inside.

"The North Base called the Dungeon Base, please answer when you hear it."

"The North Base called the Dungeon Base, please answer when you hear it."

"The North Base called the Dungeon Base, please answer when you hear it."

The correspondent was talking while wearing a pair of huge black headphones. He had more than a dozen display screens in front of him, some curves and parameters jumping.

However, this communication channel is the only one who is talking, and the opposite is the hollow current noise.

In the middle of the hall is a middle-aged man in a black military uniform. His features are stern, and his expression is majestic. The epaulette sign indicates that he is a military general.

Seeing Lu Yan coming in, he gave a slight nod to this side: "You are here."

There were also some other soldiers who came in front of and behind Lu Yan. Their ranks were not the same as their departments, but their expressions were the same cold and solemn.

There were chairs in the communication hall. They sat down and sat quietly beside Lu Yan.

The lieutenant received a communication, and after just 30 seconds, he hung up and told the officers in the hall: "After the lighthouse magnetic field observation office notified, the global magnetic field strength plummeted to five minutes ago, but our There are no abnormalities in the protected eastern pole. "

"Obviously, there was a major failure of the western magnetic pole on the other side."

Listening to Lieutenant General An Zhe, he knew the significance of magnetic poles to humans.

The magnetic field protects everything on the earth. Once it is lost, the cosmic rays and solar wind will drive in for a long time. In the short term, it will bring about a severe drought in the entire world. Exposed humans will be exposed to radiation, suffer from various malignant diseases, and then die or mutate. And if there is no magnetic field protection for a long time, the entire earth's atmosphere will be scattered by the solar wind. At that time, the world will become a dead desert.

The two magnetic poles manufactured by humans are located in the northern base and one in the dungeon base. Both of them maintain a weak magnetic field covering the world. They are indivisible. If one of them has a problem, the other will lose its effect.

There is no need for extra communication between them. Every night, when the aurora appears in the sky, they are telling each other that we are still there and still safe.

The aurora is now gone.

At this time, the personnel debugging the equipment said, "Report. The artificial magnetic field disappeared, the ionosphere was disordered, and short-wave communication was not feasible."

Lieutenant Lieutenant's brow froze, and after three seconds of silence, he said, "At all costs, open a very long wave of communication."

"Yes!"

In the era when humans lost satellites and ground relay stations, long-distance communication became extremely difficult. Only radio-radio shortwave communication could propagate signals through the ionosphere in the atmosphere. However, artificial magnetic fields are weaker than the original geomagnetism. Unstable. Now that the magnetic field has completely disappeared, the ionosphere is completely disturbed, and communication is even more difficult.

——Very long wave communication is different. It is to the ground. It uses the earth and seawater as the medium. It is stable and reliable, but the startup cost is high, and it can only use the oldest code to transmit messages.

At the same time, it is one-way. This means that unless the other party also happens to have very long wave communications at this time, they cannot communicate.

The message passed down layer by layer. Finally, the communication center received the feedback message, and the long wave communication device was turned on.

The reporter took up the instrument, and the codes of different intervals and lengths issued a monotonous "beep" sound, which was input into the system in turn, and then uploaded to the communication channel.

"The North Base called the Dungeon Base, please answer when you hear it."

Long silence.

"The dungeon base is the most well-built of the four human bases, and it is difficult to imagine that it will encounter a disaster." An officer said: "I hope it is just a malfunction of the equipment."

His voice had just fallen, and the harsh current noise suddenly sounded from the receiving device!

The sound of rustling, stabbing, chaotic as if from the infinite universe, and like the breath of a giant monster dying.

Everyone in the room held their breath until twenty seconds passed.

"Well."

"Well."

"Uh-huh-"

The telegraph sounded, and the reporter's body trembled, almost fluttering on the workbench, and quickly recorded.

Five minutes later, the Lieutenant General asked, "What did they say?"

The reporter was pale and his lips were trembling. He looked at the paper where the signal was recorded and said, "They said that ... the dungeon base ... suffered from a joint invasion of a different kind and suffered heavy losses. It was ... resisting and repairing the magnetic pole."

"The ammunition reserve is less than one-fifth ... the thermonuclear weapon reserve is exhausted, the soldiers are insufficient, request ..." He gritted his teeth and said, "Request for support."

There was silence.
