From a distance, you can even see the Yue soldiers passing the boundary marker.
The distance was quite far, and I could only vaguely identify them based on some shadows. It was probably the same when looking at them from the other side.
Currently, if you want to see clearly, the most commonly used device is a telescope.
Li Xin had a rough understanding of the terrain on this side of the border. Apart from this piece of flat land, there were jungles, mountains and even lakes along this long border line.
The terrain is quite complex, so there are still many places that need to be guarded against.
"In the early hours of this morning, there were explosions and gunshots from the woods across the street."
"We had scouts there before, and two of them were killed. We confirmed that it was a minefield. The explosion this morning... must have been caused by someone stepping on a mine." Zhang Yang came over to explain the situation to her.
He had helped Li Xin test the gun before and had some impression of Li Xin.
Although she looked weak, Zhang Yang was impressed by her because she was able to run to the border.
It is not a place that ordinary people would dare to come to without the courage to fight to the death.
And Li Xin came here without hesitation, his courage is commendable!
Stepped on a landmine?
Li Xin's heart skipped a beat, but then he remembered that He Beichen and the others were wearing detectors, so they should be able to safely avoid these landmines.
It doesn't necessarily have to be He Beichen and the others...
Li Xin comforted himself by thinking, but he took out the drone and prepared to conduct some reconnaissance to see if he could find He Beichen's location.
"What's this? Is it a new type of detector?" Seeing the drone that Li Xin took out, some soldiers immediately gathered around curiously.
These soldiers had never seen a drone before, and they found this new thing quite strange.
And it was so small that even Zhang Yang was curious about what it was used for.
"Everyone, please make some space." Li Xin reminded the soldiers around him.
Although everyone was very enthusiastic, they almost surrounded the drone tightly, making it impossible to fly.
Zhang Yang asked everyone to step back and make room for Li Xin.
Li Xin placed the drone in his hand on the open ground, stepped back a little, and controlled the drone to take off.
"It's flying! This thing can fly!" The soldiers were all excited, staring at the drone without blinking.
Li Xin controlled the drone and flew it high into the sky. It was almost invisible to the naked eye. If you stared at it closely, you could only see a small moving black dot. If you didn't look for it deliberately and just looked at the sky, you wouldn't notice it at all.
After the drone reached a sufficient altitude, Li Xin controlled it and entered the airspace of Vietnam.
Nowadays, Vietnam does not have sufficient airspace control, so drones are simply too useful.
Unlike in later times, even if the technology of drones was more mature, it would not be as easy as it is now to enter the airspace of other countries.
"It's already flown to the point where we can't see it anymore... How can such a tiny thing fly so high?" The soldiers whispered, shocked at the height to which the drone took off.
But they still don't know what this drone is used for.
Someone looked at Li Xin in confusion, and saw that she was staring at the screen on the receiver in her hand and operating it. She was not like them, staring at the sky all the time, and even rubbed the receiver from time to time.
They were curious about Li Xin's actions and came closer.
You don't know until you see it. It's shocking. Everyone was surprised by the picture displayed on the receiver in Li Xin's hand.
Isn’t this the full picture of their border?
They can even see themselves clearly on the screen.
What on earth is this magical thing?
With Li Xin's operation, the drone entered the territory of Vietnam, and all the deployments on the Vietnamese border line appeared clearly on the screen.
Zhang Yang stared at the receiver in her hand and even wanted to snatch it away to get a good look at Yue State's current defense map.
But Li Xin did not linger on this for too long. He controlled the drone to go to the forest that Zhang Yang had pointed out not long ago.
The panoramic view of the forest appeared in the picture, and many people couldn't help but gasp.
This place had obviously just experienced a brutal war. There were many intact or recognizable human corpses on the ground, but judging from the devastation on the ground, there should have been quite a few people killed in the bombing.
This forest is indeed worthy of being called a minefield. Judging from the tragic situation, there are many mines buried in the forest.
However, judging from the corpses on the ground, the Vietnamese soldiers got what they deserved this time.
Li Xin used a drone to search the woods, but there was no sign of He Beichen and the twins, whether standing or lying down. Most of them were Vietnamese soldiers.
Since they are not here, He Beichen and the others should still be safe.
"Comrade Xiao Li, the people in your research institute are amazing. They can even think of such a thing and make it. It's awesome!" The soldiers saw how easily they could see the situation in Yue State. While feeling unbelievable, they couldn't help but praise Li Xin.
Before they actually saw it, they couldn't even imagine that it was possible to do this?
Especially those scouts who have been on the border for many years, they even felt a little confused, and felt that they were not as good as the small machine in Li Xin's hand, and they were inexplicably depressed.
"This was developed by everyone at the institute. It's convenient for reconnaissance, and if discovered, only the machine will be damaged, making it relatively safer."
While explaining, Li Xin controlled the drone to search for traces on the border of Vietnam.
She remembered that when He Yubo asked her to have dinner, he told her that the researcher had separated from He Beichen and the others, and had not appeared at the border until now, and the scouts had not found any trace of him.
After the drone flew around, Li Xin not only failed to find He Beichen and the others, but he also failed to find the researchers. He could only see Vietnamese soldiers in the woods, on the mountains, and near the border.
Not only are there a large number of people, but they are also widely distributed. No wonder He Beichen and his team have not been able to break out.
Zhang Yang was standing nearby. After taking a general look at the situation in Yue State, he felt more confident and went to discuss countermeasures with the regiment commander stationed on the border.
After the initial novelty wore off, the soldiers dispersed and went to patrol the border, except for two soldiers who were assigned to protect Li Xin's safety and remained with her.
After a rough sweep, Li Xin searched very carefully this time, not leaving out a single inch of land.
This search lasted until the evening.
When Ding Cheng led the support team to the border, he saw Li Xin looking down... and playing with the remote control?
"Have you found anything?" Ding Cheng tried to hold back, but still couldn't help but stepped forward and asked.
