"Let's go..."

Guan Yu was thinking about something in his mind, said something lightly, and led Zhang Fei towards where Xun Chen was.

After a while, the two of them arrived outside Xun Chen's camp.

"Youruo, is it convenient for us to come in?"

Guan Yu's tone was very polite, showing full respect for Xun Chen.

Since the last time he suddenly broke into Xun Chen's tent and found that Xun Chen deliberately covered the papers on the desk, he never walked into Xun Chen's tent without saying a word again.

"Brother Yun, please come in."

As soon as Guan Yu finished speaking, Xun Chen's voice came from inside the camp.

When Guan Yu and Zhang Fei heard this, they opened the curtain and walked in.

I saw a piece of paper spread out on Xun Chen's desk, with something like a trebuchet drawn on it.

This time, Xun Chen seemed very generous and did not cover up the piece of paper at all.

The results of his design seem to have taken shape.

Xun Chen was standing next to the case, pointing to the couch beside him with a smile: "General Yide is also here, please take a seat."

Zhang Fei smiled and waved his hand: "Adou called us over because he has something to do, so we won't be sitting down today."

When Xun Chen heard this, he couldn't help but be curious and asked: "Oh? The young master suddenly summoned me, I don't know why?"

The last time Liu Chan called them there and had a talk at the shipyard, he was pleasantly surprised.

Now this time, will he experience other surprises?

Zhang Fei smiled awkwardly and said: "I can't explain this clearly. I think it's better to go there first and talk about it later."

"Okay, please, two generals."

Xun Chen waved his hand and asked Guan Yu and Zhang Fei to go ahead.

But Guan Yu and Zhang Fei seemed to have a tacit understanding, and they unexpectedly stood aside to make way for Xun Chen.

Xun Chen didn't show any hesitation, he smiled and nodded, then walked quickly towards the camp gate.

Although he is apparently a "strategist" invited by Liu Chan, in name, he has not been canonized by Liu Bei.

And Guan Yu and Zhang Fei did this just to make him feel their sincerity in his heart. After all, this is the treatment that only Zhuge Liang can enjoy.

After walking a few steps, Guan Yu suddenly asked: "Youruo, have you finished drawing the utensils you mentioned yesterday?"

Although he hesitated in his heart for a long time whether to ask, he finally couldn't hold back his curiosity and asked.

Xun Chen smiled and said: "Now the first draft has been completed, but it still needs to be verified. It will probably take at least some time before it can be put into practical use."

When Zhang Fei heard this, he suddenly laughed and said: "Mr.

Guan Yu smiled and said: "That's natural. If you can do it, what do you want people like Youruo and Military Advisor to do!"

"Actually, I am not born with these things. As long as the two generals are willing to study hard, they will definitely achieve something." Xun Chen said with a smile.

After a few casual conversations, the three of them arrived at the camp gate, mounted their prepared horses, and rushed to another military camp.

…

The mounts of the three of them are all good horses in the army, and the red rabbit horse under Guan Yu is one of the best horses in the world today.

In a short time, they had arrived at the military camp and hurriedly headed to the Chinese army's tent.

But inside the Chinese army's tent, the egret that sent the message before still returned to Liu Chan.

When Guan Yu saw the familiar egret, he couldn't help but ask: "Adou, why did you come to us?"

Liu Chan smiled and said, "I don't want Uncle Guan to be so impatient, so I'll get straight to the point."

After saying that, he looked at everyone's expressions and it seemed that they were all waiting for Liu Chan to speak.

He no longer hesitated and said, "I'm here today just for one thing: to change our traditional way of delivering letters."

"How to send letters? Is this the way they are used?"

Guan Yu frowned slightly and pointed at the egrets and pigeons above Liu Chan's head.

Liu Chan said with a smile: "Exactly, Uncle Guan must have seen the magic of egrets delivering letters today."

Guan Yu couldn't help but thought to himself: "It is indeed a bit unexpected for egrets to send messages. But is it really feasible to use birds to send messages?"

Although he sighed, he was still a little worried in his heart. After all, in his opinion, birds are animals after all and cannot understand human language, so how can they be messengers?

He said seriously: "But I still have reservations about this and cannot easily change the traditional way of sending letters."

Zhang Fei also said: "Yes! Some things are more reliable if they have to be done by others."

When Liu Chan heard this, he did not rush to explain, but looked at Zhuge Liang and Xun Chen to see if they also had opinions to express.

However, the two of them didn't seem to be in such a hurry. They remained silent and just watched quietly.

Liu Chan added: "Next, I will naturally explain to my two uncles why I use birds to deliver letters. There are at least three reasons for this."

"Three points? He actually thought of three reasons? I don't know if they are really reasonable!"

"Hmph! I want to see how you make these birds so obedient."

Guan Yu and Zhang Fei had their own calculations in mind.

Guan Yu was really curious, but Zhang Fei was only thinking about the hole he dug before, and he was still trying desperately to jump out!

But they just thought in their hearts and didn't say it out loud.

Just listen to Liu Chan continue: "The first and most important point is that birds fly extremely fast. Take the egret for example, it can fly five hundred miles in one hour, while the swift, swan geese and

A pigeon might fly faster."

"What? Five hundred miles an hour, isn't that faster than the second brother's red rabbit horse? Is this true?"

Zhang Fei looked shocked, but he still tried his best to control his voice.

However, this made his eyes open very wide, making him look very funny.

Guan Yu didn't seem to care, and said: "What about the second point?"

He also had a certain idea of ​​the speed of birds. Although he had not measured it specifically, he knew that it was much faster than a horse.

Liu Chan said: "The second point is safety. Whether it is an egret or other bird, it can fly at a height of more than one hundred feet. At such a height, no matter what kind of archer it is, it is safe.

You can't shoot the bird down! Our intelligence can ensure the safety of the secret."

"Well...that's true!"

"No wonder Adou wants the army to ban the hunting of egrets and other birds! After all, you can't shoot them in the air, but you can shoot them when they land."

This time, Guan Yu and Zhang Fei just nodded slightly and did not speak.

Xun Chen suddenly smiled and said: "I guess this third point is the most important."

When Liu Chan heard this, he smiled knowingly and said, "Mr. Xun is right. This third point is the most important. Without the third point, the first two points are just empty talk."

He paused slightly and said seriously: "This third point is that birds understand human nature and can understand what people say!"
