During the Goryeo War, the maximum speed of the US main reconnaissance aircraft P-51 "Mustang" was 708 kilometers per hour, the maximum speed of the main fighter F-86 "Sabre" was 960 kilometers per hour, and the maximum speed of the most advanced bomber B-29 "Super Air Fortress" was 574 kilometers per hour.

As we all know, the speed of light is 299,792 kilometers per second.

Therefore, theoretically speaking, as long as the air defense personnel are well-trained, concentrate on their missions, and wave the flag in time after discovering the target, the "early warning" effect of this air defense system can be achieved.

The principles here are easy to understand. Even a rough man like Uncle Bearded, who is obviously not well-educated, introduced with relish and full of pride.

But Zhang Zengshu couldn't laugh. He opened his mouth and wanted to explain something, but he still didn't say it.

The library of Jinling University has a rich collection of books. In the four years of college, Zhang Zengshu was addicted to games and also went to the library to read many books, including several of which were about the Goryeo War.

Several of them mentioned these "air defensemen", but the length is very small, and it is probably only a few paragraphs, less than a page. Such a content volume is enough to show that this seemingly reliable "air defense system" did not play a big role in the entire war.

In fact, if you analyze it carefully, it is not difficult for Zhang Zengshu to analyze the reasons.

Because this was the case when China had no air defense radar, insufficient air force, sufficient air defense weapons, and even no formal air defense force organization... there was no way.

This method has great limitations. For example, if the weather is not clear and cloudy enough, the US reconnaissance aircraft will surround the clouds. After entering the borders of China enough, it will be down to conduct reconnaissance missions. Then it will be too late when the "air defensemen" find them.

Moreover, it is still the early stage of the war. The Chinese volunteer army has not crossed the Yalu River and the two countries have not officially started war. The United States is not very vigilant about this side and has not invested much. Even if it discovers a transport convoy and takes into account international influence, it is unlikely that it will directly attack.

But when the war officially begins, it will be different. At that time, the US Air Force used "saturation bombing tactics".

Simply put, they divided the entire Goryeo Peninsula into fixed areas, which were assigned to bomber brigades for special care. They did not care about financial, material, manpower, and shifts, ensuring that every moment, each area had its own fighter jets patrolling and air supremacy. Then thousands of bombers took turns to bomb all areas that were not controlled by their own hands, and bombed them all over the main road or small road, as long as they seemed to be able to walk.

In this case, even if those conscientious "air defensemen" discovered the American plane and issued a warning in time, what's the point?

This is pure and stupid way to suppress others with your own will. However, even if you are stupid, it is not so easy to solve it. Even for Zhang Zengshu, who has received a modern complete knowledge system education, he could not think of any way to counter this stupid tactic under the circumstances at that time.

Therefore, he could only choose not to say a word.

...

The truck was still swaying forward, and Zhang Zengshu was still imitating the bearded uncle looking around the roof.

To be honest, this process was very boring. There were either mountains or trees on all sides, and the sky was blue. The air defensemen's flags had never waved once. The bearded uncle next to him was also a dull gourd who was not very talkative... All of this made Zhang Zengshu's novelty and excitement at the beginning slowly fade away.

Getting used to the modern fast-paced society, I usually take out my phone to read a few news when I go to the toilet. Suddenly, when I encounter such a slow-paced game, Zhang Zengshu couldn't help but feel bored, so he had to continue thinking and analyzing:

With such a slow pace, the time in the game will not be 1 to 1, right? The Goryeo War has been fighting for almost three years, so wouldn’t this game be played for three years? It won’t be so exaggerated, right?

Oh, the holographic panel can be summoned, and the button of [Exit Game] can also be clicked. The bearded uncle next to him did not show anything. It seems that the npc in the game will automatically ignore the players' strange behavior...

But waiting is not a big deal, why don’t you quit? But if you quit, what will happen next time you enter the game? Continue this character? Then when I quit, does this character still exist in the game? If there are other players, this should be an online game. It is very strange that one person suddenly is missing. For example, if you cooperate with other players, lift a box of heavy shells, and one person suddenly goes off the line and disappears, will the other person be shot in the foot? And when fighting, one person suddenly disappears and appears suddenly, which is too abrupt...

Well, if you analyze this way, after I go offline, the character of this "Guawazi" should still be in the game. I just became his controller after I go online!

Yes! That should be it!

However, I don’t know if I can change the role. If I have been in the logistics field, it will be difficult to make contributions. My shooting skills are not right! I should be able to change the role!

This is a war! The Americans continued to bomb, and there were many soldiers who died on the front line, but there were also many martyrs who fell on the logistics support line! I remember what the book said... Yes! In the first year after the war began, China lost two-thirds of the transport vehicles on the battlefield of Goryeo! My role as a transport soldier may also die!

If the character dies, the next time I log in, I will definitely not be the character. I will definitely have to change one, otherwise it will be impossible not to let me play, right?

...

As Zhang Zengshu's thoughts emanate, time slowly flows.

The sky gradually darkened, from white to green, from green to yellow, and then the sunset was filled with sunset.

Summoned out the holographic panel and looked at the time. Zhang Zengshu found that more than four hours had passed since he entered the game.

It seems that our convoy set out in the afternoon... I don't know when I will be on the front line...

Oh, by the way, what month is it today? It seems that our volunteer army crossed the river...yes! It was October 19! Then on October 25, we fought with the American devils for the first time!

Thinking of this, Zhang Zengshu turned his head and was about to ask the beard for the date.

However, before he could open his mouth, his beard spoke first: "Muwazi, it's going to be dark soon, but it's not yet time for us to relax and rest. We have a task tonight!"

As he said, he untied a small cloth bag trapped around his waist and started rummaging inside.

Zhang Zengshu didn't understand. He could understand that he had to observe the air defense during the day. What could he do at night? Will the air defense officers turn on the lights to send signals to everyone? It's dark and even if you want to find American planes, it's not easy...

The beard took out a small clock that looked like a brass, and a metal rod of the same brass color.

Then he explained: "You also know that the American devils' planes are flying day and night, and there are many people coming to investigate at night. Once the lights are turned on, they are a living target! Wait until night, our convoy cannot turn on the lights!"

"If you don't turn on the car lights, how do you see the road?" Zhang Zengshu pointed at both sides of the road and expressed confusion.

The convoy was driving on the road, and the road was not wide, and two trucks were not necessarily driven side by side. Not only was the road bumpy and uneven roadbeds, but there were also high places. If you accidentally broke the slit, the whole vehicle would have to overturn in the ditch.

"Listen to me!" Bearded face looked serious: "You must listen carefully, and you must not mislead!"

Zhang Zengshu closed his mouth and listened in a slanted manner.

"At night, it depends entirely on the skills of the driver below, and with the reminder of the moonlight and the vehicles in front, and blindly drive at night!" Beard explained carefully: "Wait until the entire fleet, only the No. 1 car in the front, is allowed to turn on the lights for a while. The squad leader Wang in their car is also the best driving skills in our even, and he is the leader of the fleet!"

"At that time, the observer on car No. 1 will ring the bell and give directions to the cars behind us. We will pass the instructions one by one. Remember, just turn left and just knock it twice. Do you know which side is the left and which side is the right? I will tell you a easy way to remember. The hand you use to eat is the right..."

"Wait!" Zhang Zengshu couldn't help but interrupt him: "I know left and right, but this bell seems wrong, right? This makes no sense, that... In this way, the driver behind can only know which side to turn immediately, but I don't know when it will turn, and how big the bend is it..."

"Hey, didn't I say it before? It all depends on the skills of the driver below!" Beard explained: "We are just a reminder here! Remind them to pay attention to it, and... what else is there... Oh, yes! Don't drive too fast and hit the car in front! Our task is very important! This is summarized by the meeting inside, this... the wisdom of the people! If you don't understand, don't talk nonsense!"

Looking at the serious expression on his bearded face, Zhang Zengshu hesitated for a while, and swallowed the words that were almost at his mouth.

Forget it, you can say that it is useful, but at worst it will be a failure.

...

Night finally came, the stars were filled with the wilderness, and the bright moon was like a hook.

The speed of the car dropped, and on the big trucks, the sound of bells being ringed one after another, and it was continuous.

Looking at the beard next to him who was stern, listening carefully, and ringing the bell seriously, Zhang Zengshu suddenly felt a little moved.
