I can't say what it feels like, but it's hopeless.

It's not that the Snake People can't find the expeditionary force on the ground, nor do they ignore the expeditionary force, they are just waiting for a suitable place and the right time before they attack.

Some memories that are impossible to forget, thinking about the tragic situation when Shimen No. 2 was broken, thinking about Wang Hu's helplessness as a brigade commander, but he could only use a gun to lure the zombies away, Gao Yuan couldn't help but panic.

"The Great Snake People could have wiped out all of our expeditionary force on the way, but they didn't move, and when we came to the Guisui Shelter, they suddenly attacked, why, why is this!"

Xinghe thought for a moment and said, "It's very simple, the big snake people are experimenting, they are looking for an effective way to destroy humans, a fast and effective way. ”

"Experiments?"

Xinghe said calmly: "You are looking for a way to completely eradicate a species, and this species is more tenacious than you think, and now, you have seen a large-scale migration of this species, so whether you will wipe out all this migration team, or study it as a sample, it depends on the choice of the researcher." ”

To put it bluntly, it is still man-made swordsmen, I am fish and meat, and the big snake people are high, and everything they do now is just research, not completely exterminate every human they see.

There are still many large human settlements on the earth, if the Great Snake People planned to kill themselves, then they could have done it a long time ago, but the Great Snake People did not, and they still have hundreds of years to study how to exterminate the human race more efficiently.

But Gao Yuan only wanted to know if it was the place where the galaxy went, which would attract the attack of the big snake people.

"You arrived at Shimen No. 2, Shimen No. 2 was attacked, and now that you are here, the big snake people will come again immediately, I am wondering, did you attract the big snake people? Don't get me wrong, I'm not accusing you, I'm just trying to figure out the connection. ”

Gao Yuan can say this, and Gao Yuan's problem is also the problem of Zhao Qiang and many others.

Xinghe thought for a while and said: "No, the first time in Shimen No. 2, it should be the big snake people who discovered my traces, so they launched an attack on Shimen No. 2, but this time it is impossible, because I don't have any characteristics for the big snake people to discover, so, I think the only explanation is that the big snake people found the migration team of the expeditionary force, so they launched an attack, you must understand one thing, that is, the behavior of large-scale migration can still be carried out now, it will definitely attract the attention of the big snake people, when we observe an intelligent species." Any anomalous behavior will attract our observation and induction, and the Great Snake People, as an interstellar colonizing civilization, will certainly do so. ”

At this moment, Liu Muyang hurriedly ran over with someone, he just glanced at Gao Yuan and Xinghe, and immediately said, "Follow me, to the headquarters!" ”

Gao Yuan and Xinghe got up and left, and after going out, Gao Yuan saw Yu Shunzhou and them who had already assembled.

Gao Yuan waved his hand at Yu Shunzhou and said, "Follow me!" ”

Yu Shunzhou and the three of them left the team and came behind Gao Yuan, and at this time, no one stopped their actions, including Zhao Qiang, who had no objections.

Liu Muyang hurriedly said: "Gao Yuan, you have experienced the battle of Shimen No. 2, and the command needs your advice. ”

said that he needed Gao Yuan's advice, but Liu Muyang was looking at the galaxy.

After finishing speaking, Liu Muyang took the walkie-talkie and said urgently: "Attention to all the expeditionary forces, all the soldiers of the expeditionary force as a reserve, fight at any time to support the battle of Guisui Yi, the platoon commander and above officers keep the radio on, and the others put the radio equipment in the safe deposit box for proper storage to prevent the enemy from releasing electromagnetic interference, over." ”

The expeditionary force and the defenders of Guisui are two teams, and if they want to fight at this time, they must fight in concert and under unified command, and naturally they can't divide each other at this time.

After Liu Muyang finished speaking on the walkie-talkie, he turned to Gao Yuan and hurriedly said, "If the defense line is lost, you will take her away!" Nothing else, understand? ”

"Yes, I understand!"

Liu Muyang took Gao Yuan and Xinghe into the headquarters, and Zhao Qiang still refused to get too far away from Xinghe, but at this time, they all stood in the corner, so as not to affect the command of the battle.

As soon as Liu Muyang entered the headquarters, he hurriedly said, "What's the situation?" ”

"There are still twelve kilometers from my Guisui Yi, and another 1,500 meters to enter the first line of defense."

There are several display screens in the headquarters, which seem to be the display of surveillance cameras, but there is not a single zombie on the screen, only the desert permafrost that has not yet melted in early spring.

"There it is!"

A staff officer shouted, he pointed to the monitoring screen and said, "Alien spaceship, one!" The sound device captures the ultrasound, 21000 Hz! It can be roughly confirmed that the alien spacecraft uses ultrasound to manipulate and command zombies! ”

The commander-in-chief said loudly: "Did the radar find it?" ”

"Radar! Did the radar make a discovery? ”

"The radar didn't find anything!"

Liu Muyang turned his head to Xinghe and whispered, "How did you do it?" You know how our radar works, right? If so, how did the Orochi do it? ”

Xinghe thought for a while and said: "It's simple, there are many ways to do it, interfering with radar reflection signals, or turning yourself into a signal black hole, there are too many means, and they are all very simple." ”

Liu Muyang sighed and said, "Got it, thank you." ”

"The zombie horde is about to enter the firepower coverage area! Please indicate whether it is covered by artillery fire! ”

The commander-in-chief looked very anxious, he clenched his fists and looked back at Liu Muyang.

Guisui No. 1 was built in a ravine, which is a big advantage, compared to Shimen No. 2, which is surrounded by plains, this advantage is too great, because if the zombies want to come, they have to come in along the narrow ravine, and they can't think that Shimen No. 2 can walk anywhere.

Now with artillery coverage, a large number of zombies can be killed, but the artillery position will be exposed prematurely, and the Snake people have absolute air supremacy, they can attack the artillery position anytime, anywhere, as they want.

Whether to kill and injure a large number of zombies at once, or to save the firepower for the most critical time, this requires the commander-in-chief to make a choice.

The artillery positions of Shimen No. 2 gradually fell silent one by one, and it was not that the shells were exhausted, and the shells in their reserves could not be exhausted, so the Shimen No. 2 Institute finally lost the cover of artillery fire, so there was only one explanation, that is, the big snake people attacked the artillery position.

The commander-in-chief of Gui Sui Yi slapped his hand on the table fiercely, and then he raised his hand, but his hand stagnated in the air.

"Order the artillery, concentrate all the fire on the No. 3 coordinate area, and wait for the order to fire!"

Abandoning the first line of firepower interception net, the commander-in-chief of Gui Sui Yi made up his mind.

Countless zombies stepped through the camera, and in all five screens, some of the camera angles were on the ground, and some were on the trees, but without exception, there were only zombies in all five monitoring screens, densely packed with zombies pouring in like a tide.

The screen suddenly switches, and the close-up is all changed to a long shot.

It's daylight, but the camera is still black.

"Zombies are about to enter the preset minefield! The front of the zombie swarm is eight kilometers away from my shelter, beware, the zombies are about to enter the minefield! ”

To deal with brainless zombies, the minefield does not have to be set up secretly at all.

On the way to Guisui and Gaoyuan, they repeatedly came to the Landmine Museum.

All kinds of mines, but not just mines, any bombs that can be exploded and cannot be dropped remotely are densely packed on both sides of a road, and in order to avoid wind and sun, those mines or bombs also have sheds, caves, safe deposit boxes, and a series of long-term storage measures to ensure that the bombs will not fail.

"The minefield electronic fuse is working fine."

"Minefield electronic fuse opens."

"Minefield staff evacuated to the shelter."

"Use monitoring from above."

The images of the five screens switched again, and this time all the images became distant shots, and at first glance, it was clear that the cameras were arranged from the hills on both sides.

This geographical advantage is too great, Gao Yuan suddenly envied Guisui Yi, if Shimen No. 2 also has this Daqing Mountain, then the result may be different.

Shimen No. 2 can only use flesh and blood as a barrier, but Guisui No. 1 is in the arms of Daqingshan, which is the geographical advantage, a complete and complete geographical advantage.

"Enter the ...... in ten seconds. Five-second countdown! ”

With a bang, the mine exploded, and it was not a manually controlled explosion, but a mine was triggered.

"Three, two, one, detonate!"

A mine explosion could not make much of a difference, but a 1,000-kilogram aerial bomb that was manually detonated remotely made a huge explosion heard by Gao Yuan, who was eight kilometers away.

There was a large crater on the ground, and the aerial bomb suspended on a wooden frame exploded at a height of five meters, which still caused a large crater to appear on the ground, but this crater was not very large, because the bomb was an air explosion.

But the zombies crowded in the valley appeared in a concentric circle, a hundred meters forward, a hundred meters back, the zombies in this distance circle disappeared instantly, and then expanded two hundred meters outward, and the zombies were all in the end, basically unable to move.

"Good!"

Not only Gao Yuan, but also the commander-in-chief of Guisui also shouted.

The garrison unit of Guisui was the army, but they emptied the arsenal of the air force, and since the planes could not go to the sky and the air force lost its effect, then they put aerial bombs on the ground and used them well.

But the tide of zombies quickly filled the space that had just been opened up by aerial bombs, and no zombies would flinch.

Landmines are just embellishments, used as early warnings, and the real effective ones are those aerial bombs, with a minimum of 250 kilograms and a maximum of 3,000 kilograms!

There are no mines in the vicinity of aerial bombs because the blast wave of the explosion can destroy the mines, but this problem can be avoided by simply configuring the mines and aerial bombs.

The zombies advanced, and then one mine after another began to explode, but compared to the 1,000-kilogram aerial bomb just now, the current mines are pediatric no matter how you look at it.

"Detonation preparation, three, two, one! Initiation! ”

There was another loud bang, and when the sound wave reached the headquarters, the explosion was like a muffled thunder in the distance, and with the sound effect and echo of the valley, an explosion had a continuous loud sound.

Liu Muyang exhaled a long breath and said, "This battlefield monitoring system is really good!" ”

The commander-in-chief of Guisui said in a deep voice: "Yes, it has just been completed and put into use for less than a month, and now it has really played a big role!" ”
