I can't tell you what it feels like, but I feel hopeless.

It's not that the Orochi people couldn't detect the expeditionary force on the ground, nor did they just leave the expeditionary force alone. They were just waiting for a suitable place and time before launching an attack.

There are some memories that are impossible to forget. Thinking about the tragic situation when Shimen No. 2 was breached, and thinking about Wang Hu's helplessness as a brigade commander, he could only draw the zombies away with a gun, Gao Yuan couldn't help but panic.

"The Orochi could clearly wipe out our entire expeditionary force on the road, but they didn't move. When we arrived at Guisui Refuge, they suddenly launched an attack. Why, why is this!"

Xinghe thought for a while and said: "It's very simple. The Orochi people are experimenting. They are looking for an effective way to eliminate human beings, a quick and effective way."

"experiment?"

Xinghe said calmly: "You are looking for a way to completely eliminate a species, and this species is tougher than you thought. Now, you have seen a large-scale migration of this species, so do you want to eliminate all this migration team, or

It is up to the researcher to study it as a sample."

To put it bluntly, humans are still the swordsmen, and I am the flesh of the fish. The Orochi people are superior. All they are doing now is just research, not the complete elimination of every human being they see.

There are still many large-scale human gathering places on the earth. If the Orochi people planned to end it personally, then they could have done it long ago, but the Orochi people did not. They still have hundreds of years to study how to exterminate human beings more efficiently.

But Gao Yuan only wanted to know whether wherever Xinghe went, it would attract attacks from the Orochi people.

"You arrived at Shimen No. 2, and Shimen No. 2 was attacked. Now that you're here, the big snake people are coming again. I'm wondering, did you attract the big snake people? Don't get me wrong, I'm not blaming you, I just want to

Figure out the connection."

Only 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, the Orochi people should have discovered my traces, so they launched an attack on Shimen No. 2, but this time it was impossible because I didn't have any characteristics that made the Orochi

People discovered it, so I think the only explanation is that the Orochi people discovered the migrating team of the expeditionary force, so they launched an attack. You must understand one thing, that is, large-scale migration can still be carried out now.

It will definitely attract the attention of the Orochi people. When we observe an intelligent species, any abnormal behavior will attract our observation and induction. As an interstellar colonizing civilization, the Orochi people will certainly do the same."

At this moment, Liu Muyang hurried 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. After going out, Gao Yuan saw Yu Shunzhou and others who had already gathered.

Gao Yuan waved to Yu Shunzhou and the others and said, "Follow me!"

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

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

He said he needed lofty advice, but Liu Muyang was looking at the galaxy.

After finishing speaking, Liu Muyang took the walkie-talkie and said urgently: "Attention to all members of the expeditionary force. All soldiers of the expeditionary force serve as a reserve team and are ready to fight to support the battle in Guisui No. 1. Officers at the platoon leader level and above keep the radio on. Others will

Put the radio equipment in the safe for safekeeping to prevent the enemy from releasing electromagnetic interference. Complete."

The expeditionary force and the garrison at Guisui No. 1 are two teams. If there is a fight at this time, they must fight together and command under unified command. Naturally, they can no longer distinguish between them.

After Liu Muyang finished speaking on the intercom, he turned to Gao Yuan and said hurriedly: "If the defense line is lost, you take her and run away! Don't worry about anything else, do you understand?"

"Yes, I understand!"

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

As soon as Liu Muyang entered the headquarters, he said anxiously: "What's going on?"

"There are still 12 kilometers away from my Guisui No. 1 camp, and another 1,500 meters to enter the first line of defense."

There are several screens in the headquarters, which seem to be the display screen of surveillance cameras, but there are no zombies on the screen, only the frozen desert soil in early spring that has not yet melted.

"Appeared!"

A staff officer shouted, pointing to the monitoring screen and said: "An alien spacecraft, one! The sound equipment captured ultrasonic waves, 21,000 Hz! It can be roughly confirmed that the alien spacecraft uses ultrasonic waves to control and command zombies!"

The commander-in-chief shouted: "Did the radar detect it?"

"Radar! Did the radar detect it?"

"The radar didn't detect anything!"

Liu Muyang turned to face Xinghe and whispered: "How did you do it? Do you know how our radar works? If you know, how did the Orochi do it?"

Xinghe thought for a while and said: "It's simple. There are many ways to do it. It can interfere with the radar reflection signal, or turn yourself into a signal black hole. There are too many ways, and they are all simple."

Liu Muyang sighed and said: "I know, thank you."

"The zombie swarm is about to enter the fire 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 is built in a ravine, which is a big advantage. Compared to Shimen No. 2, which is surrounded by plains, this advantage is too big, because zombies have to come in along the narrow ravine and cannot think about Shimen.

You can walk in all directions from the second institute.

Now using artillery fire coverage can kill a large number of zombies, but it will expose the artillery positions prematurely. The Orochi have absolute air supremacy, and they can attack the artillery positions anytime, anywhere, and as they please.

Whether to kill a large number of zombies immediately or save the firepower for the most critical moment requires the commander-in-chief to make a choice.

The artillery positions of Shimen No. 2 Station gradually became silent one by one. It was not because the shells were all fired, but the shells they had reserved could not be used up. Therefore, Shimen No. 2 Station finally lost its artillery cover. There was only one explanation, that is, the Orochi attacked.

Artillery position.

The commander-in-chief of Guisui No. 1 Division slammed his hand on the table, and then he raised his hand, but his hand stopped in the air.

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

Abandoning the first fire interception network, the commander-in-chief of Guisui No. 1 Station made up his mind.

Countless zombies stepped through the camera. In all five screens, some camera angles were on the ground and some were on trees. But without exception, all five surveillance screens only showed zombies, densely packed zombies coming like a tide.

The screen suddenly switched, and all the close shots were replaced by long shots.

It's daytime now, but the picture on the camera is still dark.

"The zombies are about to enter the preset minefield! The front line of the zombie swarm is eight kilometers away from my shelter. Be careful, the zombies are about to enter the minefield!"

To deal with mindless zombies, there is no need to set up hidden minefields.

On their way into Guisui No.1 Institute, Gao Yuan and the others visited the Landmine Museum repeatedly.

All kinds of landmines, but not just landmines. Any bombs that can explode but cannot be thrown remotely are densely packed on both sides of the road. And in order to protect them from the 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 bomb will not fail.

"The minefield electronic fuze is working normally."

"Minefield electronic fuse activated."

"The minefield staff evacuated and entered the protection point."

"Use monitoring from above."

The images on the five screens switched again. This time the images all changed to distant views, and at a glance it was clear that they were cameras arranged from the hills on both sides.

This geographical advantage was so great that Gao Yuan suddenly envied Guisui No. 1 Institute. If Shimen No. 2 Institute also had this Daqingshan, the results might be different.

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

"Enter in ten seconds...five seconds countdown!"

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

"Three, two, one, detonate!"

A landmine explosion cannot have much effect, but a 1,000-kilogram aerial bomb that is manually detonated remotely can cause a huge explosion to be heard as far away as eight kilometers away.

There was a large crater on the ground. The aerial bomb suspended on a wooden frame exploded at a height of five meters, leaving a large crater on the ground. However, the crater was not very big because the bomb was an air explosion.

However, the zombies crowded in the valley appeared in a concentric circle. One hundred meters forward and one hundred meters back, the zombies within this circle disappeared instantly. Expanding another two hundred meters outward, the zombies were all in the bottom, and basically no one could move.

.

"good!"

Not only Gao Yuan, but also the commander-in-chief of Guisui No. 1 Division also shouted.

The first guarding force in Guisui was the Army, but they emptied the Air Force's arsenal. Since the planes could not go to the sky and the Air Force was useless, they put aerial bombs on the ground and used them.

But the overwhelming tide of zombies quickly filled the space just opened by the aerial bombs, and no zombies would back down.

The landmines are just embellishments and are used as early warnings. The real effective kills are those aerial bombs, with a minimum of 250 kilograms and a maximum of 3,000 kilograms!

There are no landmines near aerial bombs, because the explosion shock wave will destroy the mines, but this problem can be avoided as long as the mines and aerial bombs are properly arranged.

The zombies advanced, and then one landmine after another began to explode, but compared with the one thousand kilogram aerial bomb just now, the landmines now are child's play.

"Prepare to detonate, three, two, one! Detonate!"

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

Liu Muyang took a long breath and said: "This battlefield monitoring system is really good!"
Chapter completed!
