Peek at my diary, Cao Cao dominates the Three Kingdoms

"Oh? And this thing? Why haven't we heard of it!" Xun You and Jia Xu looked at each other in surprise.

"That's because your relationship with him is not strong enough!" Cheng Yu was a bit showing off, but he was indeed one of the elders who followed Cao Cao.

Jia Xu asked: "Zhong De, what do you mean, there may be shadow guards with longevity in Shouchun City?"

"It's not possible, it's certain!" Cheng Yu said with certainty.

1 Thirty Chapters of Morse Code

After Lu Yan had breakfast,

Because of the sense of crisis of historical changes, after returning to the tent, he began to study military books carefully, trying to get the attribute bonuses given by the study of these books into his hands earlier.

When Cheng Yu, Xun You, and Jia Xu lifted Lu Yan's tent, they saw him studying hard.

The three of them had never seen Lu Yan working so hard. They were startled at first, and then Cheng Yu shouted: "Ha! I finally caught you! You usually look very tired, so you are hiding Secretly studying hard behind your back!"

Lu Yan didn't raise his head, and there was no change on his face, but he complained in his heart: "It's hard for some people who are interested in studying to make progress, what the hell are you doing?"

Seeing that Lu Yan seemed a little unhappy, Cheng Yu stopped teasing him. After all, if he slapped Lu Yan for making him angry, he probably would have given his life here.

Seeing that Lu Yan ignored the three of them and read the book on his own, Cheng Yu smiled awkwardly and said, "Hehe... Changsheng, actually we have something important to ask you when we come here this time. Help."

Well, it looks like I can't read this book today, Lu Yan sighed in his heart: "It's not that I don't want to read it myself, it's because others don't let me read it!"

With a sigh, Lu Yan finally put down the military book in his hand and asked, "Tell me, what do you need me to do?"

Cheng Yu looked at Xun You and Jia Xu, and saw that they had their mouths tightly shut as if you were here to communicate, so he could only bite the bullet and say, "It's actually like this..."

In less than half a quarter of an hour, Cheng Yu told Cao Cao that Lei Bo was dissatisfied with Yuan Shu, to giving them the task of breaking Shouchun, and to the fact that they encountered communication difficulties after the discussion was complete. .

After Lu Yan heard this, he was startled and said, "Mr. Cao also knows that Lei Bo is dissatisfied with Yuan Shu?"

Judging from Lu Yan's tone, he seems to have known it a long time ago?

"Lu Hussar, you already knew about Lei Bo?" Xun You finally couldn't help asking.

"Oh no, I don't know..." Lu Yan's tone was very flat, but Cheng Yu heard it, why did he always have the urge to hit someone?

Suppressing the restlessness in his heart, Cheng Yu continued: "Chang Sheng, I know that you and Feng Xiao have a very powerful spy organization... I wonder if you have a way to pass the news to Lei Bo?"

"That's it..." Hearing this, Lu Yan breathed a sigh of relief, then nodded slightly and said, "There is indeed a way."

Cheng Yu's eyes widened, and he blurted out in disbelief: "Ah! You really have it?"

Lu Yan stared at Cheng Yu with sideways eyes, and said with a sneer, "Heh! Since you don't believe me, why are you looking for me?"

"No! I, Cheng Yu, have always trusted you the most!" Cheng Yu said with a fawning smile.

"Then you still go to Mr. Cao's place to report me and Feng Xiao's skipping work?" Lu Yan took the opportunity to dig up old accounts.

"Eh... that happened a few years ago, can we stop mentioning it..." It was obviously Lu Yan and Guo Jia's fault, but why did Cheng Yu want to find a crack in the ground to sneak in? Shame?

After Xun You learned that Lu Yan did have a solution, half of the big stone in his heart finally fell to the ground.

After Lu Yan and Cheng Yu stopped bickering for a while, he asked, "Dare to ask Lu Hussar, how will you implement your plan? Do you need my cooperation?"

Lu Yan slapped away Cheng Yu who was approaching his face, looked at Xun You and Jia Xu, and replied mysteriously: "Write me the message you want to convey, and I will send it into the city tonight. "

Cheng Yu, Xun You, and Jia Xu were aroused by Lu Yan's words. After hesitating for a long time, Cheng Yu asked, "Can we wait and see?"

I thought that Lu Yan would reject the secrets related to the Shadow Guard, but unexpectedly, Lu Yan simply replied: "Yes, but you can't tell what happened tonight."

Xun You and Jia Xu's eyes lit up, and they both cupped their hands and said, "You must keep your mouth shut!"

Lu Yan is actually not afraid of them speaking out, because even if they watched his operation from the sidelines, they would still not be able to understand it 100%.

"Morse code, if you can understand it, I will take off my head and kick it for you!" Lu Yan looked at the three people who were a little excited, with a wicked smile on his lips, "If you are tormented by curiosity If you can't sleep, you can't blame me, Lu!"

......

It's midnight.

On the high ground about two miles west of Shouchun City, a paper lantern suddenly floated up!

"This thing can fly!" Cheng Yu's eyes almost popped out!

"What a miraculous thing? How did it fly?" Xun You seemed to have also turned into a curious baby.

Only Jia Xu was the calmest. After thinking for a moment, he asked, "Lu Hussar, may I ask if this thing's ability to fly has something to do with the burning turpentine on its tray?"

Lu Yan didn't expect Jia Xu to find the key so quickly, "That's right, Wen He really has a good eye."

"Corrosin burning, why can this lamp fly?" Jia Xu asked with bright eyes.

How to explain it to them?If you talk to them about air density, Archimedes' principle, etc., I'm afraid they will be regarded as mentally ill...

Lu Yan thought about it for a while, and then he simply said: "If you want to know, you can go to Chenliu Workshop to find Lao Geng. These things are made by them."

It was indeed Geng Liang and the others who did it, but it was also Lu Yan's idea at first.

"Well... Changsheng, does this lamp have a name?" Cheng Yu asked again.

"Sky Lantern, this is the official name of the workshop."

"Good name!"

Sky lanterns are actually Kongming lanterns with different names.

The rising of the sky lantern is only the first step, the purpose is to notify the shadow guards who keep watch every night that there is news to pass to them!

According to the internal regulations of the Shadow Guard, the time to use sky lanterns to deliver messages will only be at Yinshi.

So every night at this time, there must be a person on duty at night to observe whether there is fire in the sky.

Sure enough, before Lu Yan had to wait long, a sky lantern rose slowly in Shouchun City!

Here's the notification out there that they're ready to receive messages!

It's just that the sky lantern on Lu Yan's side was held by him with a rope, but the sky lantern in the city was lifted into the sky in an unknown corner of the city, and then drifted to other places with the wind.

After seeing the sky lantern rising from the city and flying away, Lu Yan also let go of the rope, and then said to Cheng Yu: "Gongda, please help me light the fire behind me!"

"Here!" Xun You came behind them and lit a small but high pile of firewood.

After the fire was lit, Lu Yan said to Cheng Yu again: "Zhong De, come and stand in my position."

"Huh?" Cheng Yu didn't know why, but he did as he did.

Lu Yan came to Cheng Yu and behind him, and after confirming that Huodui, Cheng Yu and Shouchun City were in a straight line, he pulled Xun You and Jia Xu aside and said, "Zhongde, you are in good health, and you will listen to my instructions later. Do squats."

"Squat down?" Cheng Yu was confused, "Changsheng, what are you doing?"

"Just do what I say, remember, be accurate!"

"Okay!" Cheng Yu had no choice but to agree.

Originally, Xia Houlan was supposed to do this. Since you are curious, let's be a tool man by the way...

Lu Yan unfolded the letter written by Xun You, read it through by the firelight, and finally translated the content in his own vernacular language.

"Zhongde, are you ready?" Lu Yan asked.

"All right!"

"Slow squat twice!"

"Three slow squats!"

"Twice quick squats, followed by a slow squat!"

......

Seeing Cheng Yu up and down, up and down, Jia Xu was dumbfounded.

Looking at the weird scene in front of him, Xun You twitched the corners of his mouth, and murmured, "Is this... dancing to the Great God?"

Chapter 131 is over!Cao Cao is coming in!

This is not a jumping master, nor is it squatting with radish. The way Lu Yan and the shadow guard pass messages is actually Morse code plus Chinese pinyin!

Morse code consists of two basic signals and different intervals, namely a short point signal and a long signal that lasts for a certain period of time.

That is, when Cheng Yu squatted down and stood up quickly, the fire light flashed briefly, and when he paused after squatting, the fire light kept showing for a long time.

The basic signals and intervals together form 26 letters and numbers from 0 to 9.

These 26 letters correspond to the pinyin letters of Chinese characters. Finally, according to the rules formulated in the Morse code manual, they can be coded according to the position of each pinyin.

Chinese pinyin is only taught in the shadow guards, and only the shadow guards who specialize in code translation can learn it.

In the end, each of them will hold a Morse code manual in their hands. All these secrets are even better than life.

As long as the shadow guard responsible for the code translation is not caught, even if the enemy knows the meaning of the fire light, even if they get the manual of Morse code, it will be useless, because they don't understand Chinese pinyin, everything is useless!

The operation went well tonight.

After Cheng Yu collapsed to the ground tiredly, Lu Yan clapped his hands and said, "You're done! We can go back!"

"Ah...ha! Ah...ha..." Cheng Yu panted heavily, and stammered, "This... is this... over?"

Xun You and Jia Xu were still staring at Cheng Yu tired like a dog, but suddenly they heard Lu Yan say it was done?

"End?"

"That's how the news got out???"

Xun You and Jia Xu looked at Lu Yan in disbelief, as if they had heard the most incredible miracle in the world.

"Yes, it has been passed on." Lu Yan replied with an inscrutable smile.

"But... we didn't see anyone come to get the news!" Xun You said here, and suddenly remembered Cheng Yu's dancing like a god just now...

Just at this moment, a gust of night wind blew by, and Xun You couldn't help but feel chills running down his back, "Could it be that you, Lu Huanqi, drove ghosts and gods to pick up the letter?"

"Zibuyu is strange and chaotic." Lu Yan said with a righteous face.

"Then what's going on???" Jia Xu felt that he was being driven crazy by Lu Yan, "Lu Huqi, can you just tell us how to do it?"

"Want to know?" Lu Yan asked with a faint smile.

"Think!" The three asked in unison.

After waiting for a long time, Lu Yan finally said: "Secret!"

"Ah!!!" Cheng Yu, Xun You, and Jia Xu felt like they were going crazy!

But Lu Yan had already extinguished the fire, and walked towards the camp alone.

After a long while, there was a burst of exasperated shouts from behind Lu Yan: "Lu Yan! If the old man can't beat you, you will never be able to eat and walk around today!!!"

"Keep your voice down! Don't let the enemy hear you!" Xun You hurriedly pulled Cheng Yu back.

Seeing Cheng Yu clutching his chest angrily, Xun You quickly comforted him: "What's the rush! If Lu Yan didn't tell us, Chen Liu still has a Guo Jia!!!"

Hearing this, Cheng Yu suddenly said: "Ah! That's right! Feng Xiao is also the leader of the shadow guards, he must know the secrets inside! Let's find Guo Jia first after we go back, and we must find out how Lu Yan sent the news tonight. Pass it on!"

"It's fine after I go back, but tonight...what should I do?" Jia Xu rubbed her temples and said with a wry smile, "I feel like I want to sleep well these days, I'm afraid it will be difficult..."

"Ah!!! Damn Lu Changsheng!" Cheng Yu gritted his teeth, "I don't want to...I don't want to...It's no wonder I don't want to!"

Hearing the wailing behind him, Lu Yan smiled again, and said to himself, "Oh! Tonight, I'm doomed to have no sleep..."

......

The next day, when Lei Bo and others were plotting in a remote house, the shadow guard hidden in the bookstore opened by the United Chamber of Commerce in Shouchun City sent the deciphered letter to Lei Bo.

The next step is to wait for Lei Bo to discuss the final details with the head of the Shadow Guard.

The details of the negotiation will not be repeated.

Also at midnight, a sky lantern flew out of Shouchun City.

After the sky lantern flew some distance outside the city, Zhao Yun, who had been waiting for a long time, shot down the sky lantern with an arrow.

After finding the letter tied on the sky lantern, Zhao Yun rode back to the camp and handed the letter to Lu Yan.

The general content of the letter is: At midnight tomorrow, Lei Bo will make people raise fire as a sign, and then personally lead his confidantes to open the west city gate.

But they only have a stick of incense time at most, and Ji Ling who got the news will definitely lead the army to arrive.

In the past two days, Ji Ling's monitoring of Lei Bo has become tighter and tighter. They have one and only one chance, and hope that Cao Cao will not disappoint their trust.

When Lu Yan placed the letter in front of Boss Cao and the three advisers with thick dark circles, the entire Chinese army tent was eerily quiet.
