A doctor who travels through two eras

Commander Cao and the officers nearby knew that Lin Sanqi was about to use his ultimate move, and all of them widened their eyes.

Lin Sanqi opened the box, and what appeared in front of everyone was a strange machine that they had never seen before.

Lin Sanqi asked jokingly:

"Can you guess what kind of machine this is?"

A lieutenant colonel answered uncertainly:

"Officer Lin Siling, I see a few small propellers next to it. I think it works like a helicopter. Is this a small aircraft?"

Lin Sanqi was a little surprised: "Oh, you have a good eye. What's your name?"

The young lieutenant colonel stood at attention:
"Reporting to Officer Lin Siling, my name is Xue Dingxiang, and I am the combat battalion commander of a certain unit of the 14th Army Group."

Lin Sanqi was stunned, thinking that this name was familiar:

"Captain Xue, do you have a brother named Schrodinger?"

Captain Xue was also stunned, and then quickly replied: "Report to Officer Lin Siling, my brother's name is Xue Dingguo."

Lin Sanqi burst into laughter, leaving the people around him puzzled. He was just introducing the weapons to the soldiers, so why did he suddenly show concern for their families?

"Come on, Captain Xue, I am going to give this weapon to your 14th Army. Commander Cao, let Captain Xue cooperate with me in the operation."

Commander Cao thought to himself, this little Xue is so lucky, he must have met a noble person.

When the other officers around heard this, they all groaned in their hearts, knowing that they had missed the opportunity.

They simply thought that Captain Xue was lucky. In fact, they didn't understand that it was because Captain Xue was good at observation and thinking and had a quick mind. Lin Sanqi liked this kind of young officer with an exploratory spirit, so he decided to promote him.

Therefore, luck is important, and it is also crucial to improve your knowledge and learn to express yourself at critical moments.

When Lin Sanqi was asking, there should have been other young officers who guessed that this was a small aircraft, but they just didn't say anything and missed the opportunity.

"Okay, now I'm going to assemble this aircraft. Lao Cao, Xiao Xue, and everyone else, please watch carefully."

The drone is assembled very quickly because all the accessories are available. In less than a few minutes, a medium-sized drone can be assembled.

After Lin Sanqi placed the drone on a large protruding rock, he picked up the operating handle.

The screen lit up, and General Cao, Captain Xue and others immediately gathered around to watch.

Lin Sanqi was seen looking down at the screen and operating the handle. The unmanned object on the stone next to him began to hum, attracting everyone's attention.

"Wow, it's flying."

Lin Sanqi reminded: "Don't look at the drone, look at the screen in my hand."

Commander Cao was standing closest to the scene and saw a mountain scene and a group of soldiers in green uniforms appear on the screen like a TV.

Uncertain Commander Cao looked at the screen, then at the drone in the sky, then stretched out his hand and waved, and a little man on the screen also waved.

"Hey, Comrade Sanqi, can your drone shoot like a movie? Isn't this person me? This is you."

The other officers looked at it and waved their hands, only then were they sure that they appeared on the screen. They were all very excited.

Lin Sanqi smiled and explained:
"Yes, the full name of this drone is Infrared Thermal Imager Reconnaissance Drone. Its main function is to scout the enemy. You see, the drone can take pictures of us as well as the enemy.

As long as you learn to operate the drone skillfully, you can accurately locate the enemy's position. In this way, even if it is not a close combat, our artillery fire can cover the enemy's area. Isn't it convenient?"

Commander Cao slapped his thigh and said excitedly:
"Yes, yes, yes. Originally, scouts were needed to scout the enemy's position, but sometimes it was difficult for scouts to send intelligence back in time, or they were discovered by the enemy on the way and killed or captured. Every year, the casualty rate of my scouts is the highest in the entire army.

If we had this drone, we could completely avoid this kind of sacrifice, and because the images and locations are transmitted back in real time, we can know where the enemy is very accurately.

As long as we know where the enemy is, we can formulate multiple combat plans. This kind of fighting is very exciting. The enemy's every move is under our eyes, and we can fight however we want. It's awesome!!!"

Captain Xue also added:
"And we are not afraid of the enemy's guerrilla warfare. The drone is not afraid of the enemy hiding here and there. Anyway, we can take clear pictures of them wherever they hide. That's great. This machine is very useful for enemy reconnaissance."

At this time, Commander Cao stroked his chin and thought about another question:
"Comrade Sanqi, there is a problem here. What we just said is that this kind of drone is only effective when used in plains or without any obstructions. If it is in a tropical forest like this, if the enemy hides in a tree or hides in the grass in disguise, it will be difficult for the drone to shoot from the sky."

Drones shoot from the sky down, so if there are buildings blocking the view, you won’t be able to capture what’s going on inside.

By the same token, if you are in a forest and the enemy is hiding under a tree or in a haystack, it is indeed difficult to photograph him or see him with the naked eye.

Just when everyone was feeling a little regretful, Lin Sanqi smiled:

"Lao Cao, I have already thought of your concerns. Now I will let you see the power of technology."

After saying that, Lin Sanqi adjusted the drone, and the screen suddenly changed color. On the screen, red shadows appeared in the area where everyone was.

Lin Sanqi nodded: "Everyone, count, how many red dots are there here?"

Captain Xue immediately counted and replied, "Reporting to Officer Lin Siling, there are 23 red dots here, which corresponds to our 23 people."

Commander Cao immediately understood what was going on and said excitedly:

"Comrade Sanqi, can your machine track living people?"

Lin Sanqi nodded and said:

"Yes, the principle of this machine is an infrared thermal imager. The working principle of a thermal imager is to receive infrared radiation emitted by the object being measured and convert it into a visible image, thereby displaying the temperature distribution of the object.

Therefore, as long as it is a living thing, including humans and animals, or something with a heat source, such as a fire, hot water, etc., it can be clearly photographed.

Now let's compare them. Look carefully and find the 200 people hiding in the forest."

The drone started to fly higher, then slowly moved toward the surrounding area.

In the 1960s, Wutong Mountain was not yet a national forest park, but a relatively primitive tropical forest with dense vegetation.

What everyone saw in the camera was lush greenery. Everyone's eyes widened, and they couldn't see where the 200 soldiers lurking in the forest were.

This is indeed a disadvantage of using drones for reconnaissance.

After all, the south is mountainous and forested, unlike the North China Plain, which is flat and vast. It is difficult to hide someone, or you can only fight underground.

Commander Cao shook his head: "I can't find him. I can't find him at all."

Lin Sanqi chuckled and adjusted the mode to infrared thermal imaging, and then the lens in front of him changed.

Many red dots appeared in the camera, and everyone screamed:
"Wow, I see it, I see it, it's hidden here, and here."

Everyone was excited and quickly pointed out the locations of the lurking "enemies" one by one.

Commander Cao sighed:

"Okay, this is really a magical tool. With this, the enemy can't hide no matter how hard they try. Hey, these two red dots are running so fast, why do we need to test the moving target?"

Lin Sanqi laughed and drove the drone towards the two fast-moving red dots:

"Lao Cao, look carefully, these are two wild boars."

Everybody started laughing too.

Commander Cao laughed at himself:

"That's great. When we go hunting in the future, we can find prey based on this infrared thermal imaging technology. Wouldn't we get a lot at the end of the day?"

Captain Xue was also amazed:

"This is a treasure. This is a treasure. With this reconnaissance aircraft, the enemy has nowhere to hide. By the way, Officer Lin Siling, how far can this drone fly? How long can it fly?"

Lin Sanqi thought that this young officer was really smart and the questions he asked were very crucial.

"The flight distance and duration of a drone depends on the capacity of its battery. For a drone like the one above our head, it can fly 20 kilometers without any problem and can stay in the air for up to 2 hours." (End of this chapter)
