"Emergency power is on."

"Emergency intercom channel is open."

"Emergency defense has been activated."

"The ventilation system is on."

"The window for radiation protection has dropped."

"Please ask all departments to stand by where they are."

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

As the sound fell, dull "clang" sounds continued in all directions. Anzhe looked at the corridor again, and the cold steel curtain wall suddenly fell down, blocking all the windows. It looked very thick - he thought of the poet

If so, once the magnetic field disappears, rays and solar wind from the universe will immediately hit the earth's surface.

So he knew that when Lu Feng dragged him out of the corridor just now, he was leaving the range that cosmic radiation could reach - and as the main city is a building from the peak era of human technology, the thickness and special materials of the walls can protect against radiation attacks.

After the lights in the United Front Center building went on and off like crazy, they turned on steadily again, but this time the lights were much weaker than before, showing a feeble pale color.

The voice of a researcher dialing up the communication line came from the nearest laboratory. He was so anxious that his voice was so loud that it could be heard throughout the corridor.

"d1342 requests to increase the power supply! The instrument cannot stop!"

A voice also came from another laboratory: "D1343 requests emergency power supply, otherwise the precious sample will be inactivated."

An Zhe didn't know who would answer their request and whether it would be satisfied. He looked in the direction of D1344 and subconsciously grabbed the corner of Lu Feng's sleeve.

Lu Feng looked down at him and said, "It's okay."

An Zhe nodded.

The radio continues to broadcast.

"Please ask the personnel in charge of the Equipment Center, City Defense Station, Emergency Response Department, and Logistics Supply Department to go to the first conference room on the 17th floor of the United Front. Please do not take the elevator and use the emergency passage to go up and downstairs."

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

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

The radio volume was turned up to the maximum, and the lingering sound echoed in the corridors.

An Zhe looked at Lu Feng: "Shall we go back to the lighthouse?"

"I'm waiting for the order." Lu Feng looked at the other side of the covered bridge, as if thinking about something, and then returned to An Zhe: "Don't run around, follow me."

An Zhe said: "Okay."

Just listen to the broadcast: "Please ask the heads of the command office, joint staff, tribunal, and operations center to go to the communications center on the 14th floor of the United Front. Please do not take the elevator and use the emergency exit to go up and down the stairs."

As soon as he followed Lu Fie into the door of the communication center, An Zhe heard the voices inside.

"The northern base is calling the underground city base. Please answer if you hear it."

"The northern base is calling the underground city base. Please answer if you hear it."

"The northern base is calling the underground city base. Please answer if you hear it."

The correspondent was wearing a pair of huge black headphones and was talking. There were more than a dozen display screens spread out in front of him, with some curves and parameters jumping around.

However, he was the only one talking in this communication channel, and all that came from the other side was hollow electrical noise.

In the center of the hall is a middle-aged man in black military uniform. He has stern features and a majestic expression. The logo on his shoulder straps indicates that he is a military lieutenant general.

Seeing Lu Feng come in, he nodded slightly and said, "You're here."

There were some other soldiers who came in behind and behind Lu Feng. Their military ranks and departments varied, but their expressions were all the same cold and solemn.

There were chairs in the communication hall. They spread out and sat down. An Zhe sat quietly next to Lu Feng.

The lieutenant general received a communication. After just thirty seconds, he hung up and said to the officers in the hall: "I was notified by the Lighthouse Magnetic Observation Office that the global magnetic field intensity dropped to 0 five minutes ago, but what we have

No abnormalities occurred in the protected eastern magnetic pole."

"Obviously, there is a major failure in the western magnetic pole on the other side."

An Zhe listened to the lieutenant general's words, and he knew the significance of magnetic poles to human beings.

The magnetic field protects everything on the earth. Once it is lost, cosmic rays and solar wind will drive in, which will bring about a severe drought in the entire world in the short term. Exposed humans will be exposed to radiation, suffer from various malignant diseases, and then die or mutate.

And if there is no protection from the magnetic field for a long time, the entire earth's atmosphere will be blown away by the solar wind. At that time, the world will become a desert of death.

The two magnetic poles created by humans, one located in the northern base and the other located in the underground city base, both maintain the weak magnetic field covering the world and are inseparable. Once one of them has a problem, the other will also lose its function.

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

Now the aurora has disappeared.

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

The lieutenant general frowned. After three seconds of silence, he said: "At all costs, activate the very long wave communication."

"yes!"

In an era when humans have lost satellites and ground relay stations, long-distance communication has become extremely difficult. Radio - radio shortwave communication can only propagate signals through the ionosphere in the atmosphere. However, the artificial magnetic field is weaker than the original geomagnetism after all, and communication is inherently difficult.

It is unstable. Now the magnetic field has completely disappeared, the ionosphere is completely chaotic, and communication is even more difficult.

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

At the same time, it is one-way. This means that unless the other party happens to have VLW communication turned on at this time, communication cannot be made.

The message was passed layer by layer, and finally, the communication center received feedback that the very long wave communication device had been turned on.

The telegraph operator picked up the instrument, and the telegram codes with different intervals and lengths made a monotonous "beep" sound, were entered into the system one after another, and then uploaded to the communication channel.

"The northern base is calling the underground city base. Please answer if you hear it."

A long silence.

"The underground city base is the most well-constructed of the four human bases. It is hard to imagine that it will encounter a disaster." An officer said: "I hope it is just an equipment failure."

As soon as he finished speaking, harsh current noise suddenly sounded from the receiving device!

The rustling and tingling sounds were so chaotic that they seemed to come from the infinite universe, and also resembled the dying breath of a huge monster.

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

"Beep."

"Didi."

"Beep, beep——"

When the telegraph sounded, the telegraph operator's body trembled, and he almost threw himself on the workbench, recording quickly.

Five minutes later, the lieutenant general asked: "What did they say?"

The operator's face was pale and his lips were trembling. He looked at the paper recording the signal and said: "They said... the underground city base... suffered a combined alien invasion and suffered heavy losses. It is... resisting and the magnetic pole is being repaired."

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