Chapter 2596
Qiao Liancheng thought for a moment.
It's definitely safer to deploy a drone, so I nodded and said:
"Go get it, I'll wait here."
Jiang Wan agreed and ran towards her car.
After fiddling with it for a while, he ran over with a box, took out a drone from it, and quickly launched it.
Then, I attached a flashlight to it for illumination and lowered the drone down through the opening.
Fortunately, the car Jiang Wan drove this time was a public vehicle from the Digital Home, and there was a laptop inside.
Laptops are so heavy these days, you could use them to crack walnuts.
But it's still quite comfortable to use in this remote area.
After Jiang Wan lowered the drone.
However, there was no way to see what was happening inside because there was no internet access.
The current internet is in a terrible state, not to mention connecting to satellites.
Jiang Wan could only try to keep the drone flying in a straight line to avoid the surrounding area being too narrow and causing the propeller to hit the drone and crash.
She simply wanted to use the drone's lighting and filming to see what was going on down there.
The first operation was very careful. The drone was lowered about one meter before it was slowly lifted into the air.
Next, I took out the floppy disk stored on the drone and put it on my laptop.
As she placed it, Jiang Wan muttered, "When will those small memory cards be available?"
It feels like I need to be involved in every industry to achieve my goals.
Nothing is achieved overnight, which annoyed her.
After inserting the floppy disk into the laptop, it took several minutes to read the contents.
Below should be a huge space, even though it only descends to one meter.
Jiang Wan still found that there was almost no boundary around her.
She hesitated for a moment and looked at Qiao Liancheng.
Qiao Liancheng said, "We can try moving down two meters further, or spreading outwards to the surrounding area."
Jiang Wan nodded and handed the drone over to Qiao Liancheng.
Men seem to be more accurate than women when it comes to manipulating these things.
The two of them lay there fiddling with it for a long time.
I'm very worried about Hai Rongtian's situation.
Perhaps because of the commotion outside, Jia Haixia woke up, and Ping An woke up as well.
Only Yuanyuan and her two children were still asleep.
Hai Rongtian looked around and felt that it was relatively safe, and the few people not far away were not too far away either.
At least we can still see their backs.
So Hai Rongtian said to Jia Haixia, "You stay here and watch the child, I'll go check what's going on."
Jia Haixia nodded.
Before leaving, Hai Rongtian stuffed a short knife into Jia Haixia's hand.
He handed her a bell and said, "If there's a problem, call for help. If all else fails, ring the bell. I'll come back if I hear anything amiss."
Jia Haixia nodded, and then Qiao Ping'an said, "Grandpa, don't worry, I'll protect them."
Ping An learned martial arts from Qiao Liancheng from a young age.
Although Qiao Liancheng has not been in Yanjing recently, Ping An's martial arts skills have not declined.
In fact, after arriving in Yanjing, there were always some people who bullied him because of his accent and treated him as an outsider.
Ping An then diligently practiced martial arts.
He can now fight on equal terms with the people at the martial arts school, so Hai Rongtian believed him when he said he would stay to protect him.
When Hai Rongtian ran over, he saw Qiao Liancheng and Jiang Wan lying at the cave entrance, trying their best to operate the drone.
Judging from his cautious demeanor, not daring to be too aggressive, Hai Rongtian said:
"I see you have a lot of stuff in your car. Do you have anything like a radar?"
"It's like how bats emit sound waves."
"If the sound waves are some distance away or some distance away, they will produce different sounds."
Jiang Wan looked at him in surprise: "How did you know our company has this?"
This thing was developed by Kong Ling. Some time ago, when Qiao Liancheng and Jiang Wan were researching how to fight against enemy fighters.
Kongling then thought of using the sonar effect of bats.
Could we emit a counter-vibration wave and then reflect the electronic jamming waves from enemy aircraft back?
This was just an idea, and that's how this little gadget came about.
The result was rather pointless.
This thing can only be used as a toy.
It somewhat mimics electronic signals, but it can't quite do that.
Kong Ling said, "It might be more effective against things like mosquitoes and insects, such as mosquitoes in the summer."
"With this thing interfering, I'm afraid we won't be able to find our target and will just get dizzy from flying."
"It could be given to children to play with."
So Jiang Wan left it in the car, intending to use it as a mosquito repellent for her two children in the summer.
Now that Hai Rongtian has brought this up, Jiang Wan says, "I actually have some in my car."
So she went back to the car and took the little thing out.
It's just a tiny bit.
Hai Rongtian said, "Put this thing on your drone."
"This way, when it emits sound waves, they will bounce back when they encounter a wall. In other words, by using the length of this sound wave, we can determine how far the drone is from the wall."
Jiang Wan said, "The problem is, I'm afraid I can't hear very clearly. I'm not an animal, and I don't have that kind of hearing."
Hai Rongtian said, "The space below is enclosed. There should be an echo, and the sound will probably be different."
The group tried it and found that they could indeed hear a faint echo.
During the day, it's impossible to use this thing at all; it's okay at night.
After several attempts, the drone went down and came back several times, confirming that the space below was very large.
The height from the ground to below is at least ten meters.
At this moment, Jia Haixia rang the bell.
Everyone was startled, thinking something had happened here, and hurriedly ran back.
When they ran back to the vicinity of the tent, Jia Haixia said, "The woman has woken up."
Jiang Wan and the others looked anxiously at the woman.
The woman was indeed awake. She opened her eyes and looked around in a daze. When she saw Jiang Wan and the others approaching, she hurriedly said:
"They all fell. I grabbed onto something nearby and barely managed to climb back up."
"But they all fell down."
Jiang Wan frowned and asked, "Why did they fall?"
"I don't think that opening is very big; it can only accommodate one person falling in. Why did all of you fall in?"
The woman seemed a little aggrieved, and she said:
“I don’t know what happened. At first, Xiao Si fell in, and we thought it was a trap.”
"I came over to check on him, but then everyone else started falling, and I quickly grabbed a rock next to me."
"It felt like something passed by me and hit me hard."
"Then I passed out. Before I lost consciousness, I desperately climbed up, and I only fainted after I hit the ground."
