"Lu Xun!"

Hubbard shouted, and saw Lu Xun's fingers pressing the edge of the cabin door tightly until blood turned white.

The drooping eyelashes and empty eyes seemed to be trying to cover up the owner's loss of composure, but the slightly trembling knuckles had already exposed the truth.

In this sea of ​​fire, the voice was hoarse, but still calm: "Prepare to attack."

Unexpectedly, this attack was not difficult.

The monsters' attacks seemed to slow down a lot at that moment. They seemed to finally stop attacking the crowd stubbornly and frantically, looking for something, and were just carrying out an ordinary hunt.

In this extraordinary hunt, some monsters turned around and headed for the abyss, while others continued to attack the institute. Most of the monsters that had entered the institute were strangled by the Simpson Cage, which then ran out of power and gradually extinguished itself. However, the institute began to fight back and effectively resisted their attack.

As for the surrounding monsters, they were firmly blocked by pl1109's micro-nuclear bombs and heavy weapons. This was a wilderness, and except for the tiny courtyard on the top of the mountain, there was no need to be cautious. Just like the vast plain above the underground city base, the fighter formation was truly playing its role here.

The surrounding monsters were gradually killed.

Heavy weapons set up an insurmountable line of defense filled with smoke and dust around the institute. The monsters in the abyss naturally have an IQ worth mentioning. They thought for a while, and the monsters behind them turned around and retreated.

When they came, they suddenly surged like a tsunami, and when they left, they slowly fell like a tide. Two hours later, this sad mountaintop returned to silence.

Red, white, and various liquids filled the open space in front of the institute. At noon, when the sun was the most dazzling, blood stains shone.

pl1109 slowly landed. Human military officers visited the white building where Polly Jon was.

They didn't seem to have any grudges against the institute because of the difference between humans and aliens, and asked enthusiastically what happened just now. The Highland Institute also regarded them as compatriots. After explaining the stable frequency, Polly Jones, as the leader of the institute, thanked the North Base for its selfless support.

"How is the base?" I asked at last.

However, there was only silence in response.

In this suffocating silence, a voice suddenly came from the emergency communication channel.

"This is the Northern Base." Dr. Ji's voice trembled slightly. "Hello, I'm asking about the situation."

"This is the Highland Research Institute, hello." Polly Jones said, "The monsters have receded, and the number of survivors is thirty-seven."

"The Northern Base... the monsters are receding." Dr. Ji's voice was hoarse in the sound of electric current: "The base personnel retreated to the core laboratory in the center of the magnetic field. The number of survivors... three hundred and ten, and one hundred and thirty-six seriously injured."

"The air strikes are ineffective, thermonuclear weapons cannot be used, light weapons are in urgent need, and troops are in urgent need." Jones gasped heavily, as if suppressing something: "The monsters are no longer attacking humans crazily, but they still have not given up on using existing humans as prey. I... we are still defending the core laboratory defense line..."

Polly stared silently at the blank screen.

"Are you injured?" Dr. Ji finally said.

Dr. Ji's voice finally added a touch of emotion to the formulaic tone: "I am injured, Mr. Polly. We have never met, but..."

He did not continue. After a quick breath, he changed the subject: "I have served the base for ten years. I think I am very talented, but I have not helped the base to achieve any breakthrough results, Mr. Polly."

"In the past, I heard from the people in the northern base that you were in charge of developing a gene detection device. Now, they say that you extracted a stabilizing solution, which may be the reason why the artificial magnetic pole did not go wrong in today's distortion storm."

"Thank... Thank you." Dr. Ji said on the other side: "We will defend the magnetic pole until the last moment. But please also... be prepared for the magnetic field to disappear... Please... please take care of yourself."

Then there was only the sound of chaotic breathing.

In the intermittent sound of electric current, there were shadowy noises, command sounds, gunshots, screams, objects toppling over, and walls collapsing.

There was silence in the Highland Research Institute.

Finally someone asked, "Then...are we still going to die?"

If the northern base has no support, the magnetic field covering the entire world will still not escape the fate of disappearing. The pl1109 formation brought firepower support, but it is ultimately limited. How many days can the Highland Research Institute hold on? With endless sacrifices and a stable frequency, there is still no hope of survival.

The vision of mankind is still the full moon in the water.

No one answered.

Deathly silence, the air is a mass of solidified rotten meat.

Someone laughed softly a few times, like a knife scratching frozen rotten meat, cracking a mocking wrinkle.

However, in this dead silence, the hissing sound of the current suddenly paused, and another strange voice came.

"Hello." The other party's voice was slurred and only the syllables could be barely distinguished.

"I'm sorry, the equipment is malfunctioning and has not been able to send a message to the emergency communication channel. This is the command center of the underground city base."

The air stagnated.

"This is the Highland Research Institute." Polly replied: "May I ask how the underground city base is doing?"

"The underground city base is fine." The other party said: "After the monsters attacked the base collectively two months ago, the base closed the ground gate and adopted a full lockdown mode. Today, the ground is surrounded by a large number of monsters, but because of the geographical advantage, it has not been invaded."

Polly was slightly moved.

But the other party continued: "The Underground City Base thanks the North Base for its selfless assistance two months ago, and especially thanks Colonel Lu Xun for making the decision to rescue."

"After learning about the situation in the north, the North Base provided us with supplies, weapons, and ammunition equipment, which have all been loaded on transport aircraft. The transport aircraft formation took off from the Underground City Base six hours ago, accompanied by a thousand lightly equipped paratroopers, and is expected to arrive at the North Base for rescue in half an hour."

Then he said: "Please hold on for thirty minutes, North Base."

There was a sound like something sliding down, and after the sound, Dr. Ji's voice was low, but firm.

"We can do it."
