Little Mushroom

"Emergency power is on."

"Emergency intercom channel activated."

"Emergency defense is on."

"The ventilation system is on."

"The radiation protection window has dropped."

"All departments, please stand by."

In the corridor, amidst the chaotic footsteps and shouts, the radio was turned on, and it was no longer a mechanical voice, but a human female voice.

As the sound fell, the dull "bang bang" sound continued to open in all directions.An Zhe looked at the corridor again, the cold steel curtain wall fell suddenly, covering all the windows, it looked very thick - he remembered the words of the poet, once the magnetic field disappears, the rays from the universe and the solar wind will immediately hit the surface of the earth .

So he knew that Lu Yan dragged himself out of the corridor just now, out of the possible reach of cosmic radiation - and the main city was a building in the peak era of human technology, and the thickness of the walls and special materials could defend against radiation attacks.

After flickering frantically, the lights of the United Front Center building turned on steadily again, but this time the lights were much weaker than before, presenting a feeble paleness.

The voice of the researcher dialing the communication came from the nearest laboratory. He was so anxious that the voice was so loud that the whole corridor could be heard.

"D1342 requests to increase the power supply! The instrument cannot stop!"

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

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

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

An Zhe nodded.

The broadcast continued.

"Responsible personnel from the Equipment Center, Urban Defense Office, Emergency Response Department, and Logistics Supply Office are requested to go to the first conference room on the 17th floor of the United Front. Please do not take the elevator, use the emergency passage to go up and down the stairs."

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

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

The sound of the radio was turned up to the maximum, and the reverberation echoed in the corridor layer by layer.

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

"I'll wait for the order," Lu Feng looked towards the other side of the covered bridge, as if thinking about something, then turned his gaze back to An Zhe: "Don't run around, follow me."

An Zhe said, "Okay."

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

As soon as Lu Feng entered the gate of the communication center, An Zhe heard voices from inside.

"The northern base is calling the dungeon base, please answer if you hear it."

"The northern base is calling the dungeon base, please answer if you hear it."

"The northern base is calling the dungeon base, please answer if you hear it."

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

However, only he was talking on this communication channel, and there was only hollow electrical noise coming from the opposite side.

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

Seeing Lu Feng coming in, he nodded slightly to this side: "You are here."

There were also some other soldiers who came in with Lu Feng. Their military ranks were different from their departments, but they all had the same stern and solemn expressions.

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

The lieutenant general received a communication, and after just 30 seconds, he hung up and said to the officers in the hall: "According to the notice from the lighthouse magnetic field observation office, the global magnetic field strength dropped to zero 5 minutes ago, but our protected No anomalies occurred at the eastern magnetic pole."

"It is clear that there is a major failure of the western pole on the opposite bank."

An Zhe listened to what the lieutenant general said, he knew the significance of the magnetic pole to human beings.

The magnetic field protects everything on the earth. Once it is lost, cosmic rays and solar wind will drive straight in. In a short period of time, the whole world will be severely drought, exposed humans will be exposed to radiation, suffer from various malignant diseases, and then die or mutate.And if there is no protection of the magnetic field for a long time, the entire earth's atmosphere will be blown away by the solar wind, and at that time, the world will become a dead desert.

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

There is no need for redundant 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 is gone.

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

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

"Yes!"

In the era when humans lost satellites and ground relay stations, long-distance communication became extremely difficult, and they could only transmit signals through radio-radio short-wave communication through the ionosphere in the atmosphere. However, the artificial magnetic field is weaker than the original earth's magnetic field after all. Unstable, now the magnetic field has completely disappeared, the ionosphere is completely disordered, and communication is even more difficult.

——The very long wave communication is different. It is ground-based, using the earth and sea water as the medium, stable and reliable, but the startup cost is high, and only the oldest code can be used to transmit messages.

At the same time, it's one-way.This means that unless the other party happens to have turned on the very long wave communication at this time, they cannot communicate.

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

The operator picked up the instrument, and the codes with different intervals and lengths made a monotonous "beep" sound, and were input into the system in sequence, and then uploaded to the communication channel.

"The northern base is calling the dungeon base, please answer if you hear it."

There was a long silence.

"The dungeon base is the most well-constructed among the four human bases. It's hard to imagine that it will encounter disaster." An officer said: "I hope it's just a malfunction of the equipment."

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

Rustle, rattle, chaotic as if from the infinite universe, like the dying snort of a gigantic monster.

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

"Di."

"Beep."

"Beep, beep—"

When the telegram sounded, the body of the telegrapher trembled, and he almost threw himself on the workbench to record quickly.

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

The transmitter's face was pale and his lips were trembling. He looked at the paper recording the signal, and said, "They said...the dungeon base...had suffered a joint invasion by alien species and suffered heavy losses. They are...resisting and repairing the magnetic pole."

"The ammunition reserve is less than one-fifth...the thermonuclear weapon reserve is exhausted, and the number of soldiers is insufficient. Please..." He gritted his teeth and said, "ask for support."

There was silence.
