The queen's mother and daughter didn't mention it for the time being, but said that Lu Zhi and King Yue had almost eaten and were chatting.

"Lu Zhi, I'll tell you a story."

It's coming, it's finally here, after so long of foreshadowing, the expected task has finally come, Lu Zhi hurriedly pricked up his ears.

"Legend has it that there is a fairy named the Queen Mother of the West...... "King Yue's opening is still a mythical story.

"It is said that there are 3 blue birds around her, who can fly over thousands of mountains and rivers to transmit information, and can also transmit the sound of happiness, auspiciousness and happiness to the world."

Lu Zhi's eyes narrowed slightly, this legend also existed in the world before he crossed over, but it is not surprising that this continent can even be unearthed with the Four Books and Five Classics, and it is normal for some similar legends to be found.

"What can you think of?" King Yue stopped at the point, with a look of excitement and anticipation, waiting for Lu Zhi to answer.

Antarctic immortals? Three Emperors and Five Emperors? Dayu controls the water? …… Lu Zhizhi thought a lot, but it was not suitable to say it, he thought for a while, "Could it be the book of Hongyan?" Flying Pigeon Biography? ”

King Yue's excited straight thighs finally found the feeling of being a fellow practitioner, "Yes, yes, I know that you can think of it." ”

Of course, this Lu Zhi could think that in the world before he crossed over, the folk tried to use the wild goose to pass on the book according to this legend, and then later, it gradually evolved into the flying pigeon to pass the book.

"Hiss~~~" Lu Zhi shook his head, "Father, this idea of yours is good, but unfortunately it is not so reliable." ”

"Oh, you still have research on this? Tell me quickly, why is it unreliable? King Yue was still smiling, without a trace of loss.

"Okay, since my father wants to hear it, then I'll talk about it." Lu Zhi dipped his hand in some wine and nodded on the table, "First of all, the wild goose or the flying pigeon does fly fast, at least much faster than the horse. ”

King Yue nodded, it was for this reason that he thought of using birds to transmit messages under the vague reminder of the black armor guard, nothing else, just one word - quick!

What's the most important thing about delivering information? Timely enough, fast enough!

In particular, intelligence organizations like the Black Armor Guard have extremely high requirements for the speed of news transmission, so they will constantly think about how to deliver information faster.

"But it just looks fast." Lu Zhi dipped in the wine again and began to write and draw on the table.

King Yue gestured, and Wei Zhong hurriedly withdrew the plate.

Sure enough, Lu Zhi's painting was blocked, and when Wei Zhong withdrew his things, he also raised his head and politely said thank you.

Lu Zhi drew a question of distance, "In fact, the distance traveled by a flying pigeon and a fast horse is similar every day. ”

King Yue moved a stool and sat on the side, and then Wei Zhong also came back, and the shadow was also there.

Lu Zhi was very attentive and didn't notice this, he continued to explain, "Fast horses generally run 180 miles a day, and by changing people and horses, they can reach more than 300 miles, and the limit value can even reach 800 miles. ”

This involves an allusion to the "Eight Hundred Miles Urgent", saying that it was during the Anshi Rebellion, and it took less than 6 days to send a letter to Tang Xuanzong.

Converted, uh, it's less than 800 miles, about more than 500 miles, Lu Zhi just said it's smooth.

King Yue looked at the shadow, the shadow nodded slightly, Da Yue's horse was naturally not so fast, but Lu Zhiyang's horse did, so it was not nonsense.

"Let's talk about pigeons, to be honest, I don't know how fast they can fly." Lu Zhi spread his hands, "But this is not important. ”

"When flying pigeons need to rest, need to eat and drink, the key is to eat and drink, yes, let's talk about eating and drinking, the pigeon is in the process of flying, food can not be guaranteed, it is likely to be busy looking for food along the way."

Speaking of this, Lu Zhi also smiled, thinking about it carefully, it was quite funny.

"Speaking of rest, the pigeon is flying in the sky, no one knows what route it takes, and when it will rest, we can't build a post station in the sky, right?"

Saying that, Lu Zhi smiled again, "So, don't even think about the relay." ”

In fact, according to Lu Zhi's speculation, the "Flying Pigeon Biography" should not be able to reach the speed of the post station's "800 miles expedited".

"Oh, of course, the short range doesn't count, the pigeon can fly after all, and if the distance is too short, it may be there with a flap of its wings." Lu Zhi finally explained.

That's the truth, King Yue nodded, this time he didn't need to ask the shadow.

…………

"Besides, the most important thing is that the flying pigeon biography is mainly unreliable!" Lu Zhi explained, "It's okay usually, just like now, even if there are trained carrier pigeons, we don't dare to use them!" ”

"The horses are running on the ground, there are people riding horses to control, and there are post stations set up in advance every how far away, there are our people all the way, how safe is the intelligence?"

"But there are too many uncertainties about the flying pigeon."

Lu Zhi wrenched his fingers, "For example, will it rain, the pigeons are busy hiding from the rain; Will you encounter delicious food, the pigeons are busy eating, and after eating, they will delay the speed again. ”

"In addition, during the flight, the pigeon may be preyed upon by eagles and other animals, and the information will be lost." Lu Zhi gestured, "Or if you meet some unlucky child, play blindly, and then hit it down when you play with the slingshot." ”

"The worst-case scenario is for the letter to fall into the hands of the enemy." Lu Zhi sighed, "When the time comes, it is still a good situation for the other party to intercept the letter, if you replace it with the wrong information and continue to fly, it will cause big trouble." ”

Hearing this, King Yue gasped and waved his hand again and again, "No, that's not good, Lone would rather run to death than use a pigeon to convey military information." ”

The shadow was a little unwilling, originally according to his assumption, it was feasible to fly a pigeon or a flying bird, but what Lu Zhi said was also reasonable,

Although the probability of a carrier pigeon being intercepted is not very high, no, it can be said to be quite low, but fighting a war is not child's play, and even the slightest negligence can lead to defeat.

If you are defeated by a carrier pigeon, it is too unjust to believe that those warriors will not be blind even if they die.

Whew, fortunately, fortunately, I didn't go directly to the book! …… Shadow secretly rejoices that he feels careful enough to be a step ahead.

King Yue glanced at the shadow and didn't say anything, at this time, he returned to smiling, "What you said makes sense, but this pigeon can't do it, it doesn't mean that other things can't do it, right?" ”

"Probably not." Lu Zhi had no basis, he just felt that the fact that the Flying Pigeon Biography had taken so many years in the world he had crossed over was enough to show that it should already be the most suitable among the options.

"Hey, as long as you're still a mechanic, you don't have the thoughtfulness to think about it." King Yue was quite complacent, "Ordinary flying birds naturally can't be, hehe, what if it's a trap flying bird?" ”

"Trap Birds?" Lu Zhi was stunned for a moment, "If you don't eat or drink, you won't get tired, this thing is suitable, but it's a pity that I can't do it." ”

King Yue patted his chest, "It's going to be fine, there are drawings alone." ”

Lv Zhi: "......"
