This is not a master dance, nor is it a carrot squat. The method used by Lu Yan and the shadow guard to convey messages is actually Morse code plus Chinese Pinyin!
Morse code consists of two basic signals and different intervals, namely a short dot signal and a long signal that lasts for a certain period of time.
That is, when Cheng Yu quickly squatted down and stood up, the firelight flashed briefly, and when he paused after squatting, the firelight remained exposed for a longer period of time.
The basic signals and intervals together form the twenty-six letters and the numbers 0 to 9.
These twenty-six letters correspond to the pinyin letters of Chinese characters. Finally, according to the rules established in the Morse code manual, it is encoded according to the position of each pinyin.
Chinese Pinyin is only taught in shadow guards, and only shadow guards who are specifically responsible for code translation can learn it.
Finally, 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 code translation is not caught, even if the enemy knows the meaning of the fire, even if they get the Morse code manual, it will be useless, because they do not understand Chinese pinyin, everything will be in vain!
Tonight's operation went smoothly.
After Cheng Yu collapsed to the ground tiredly, Lu Yan clapped his hands and said, "It's done! We can go back!"
"Ah... ha! Ah... ha..." Cheng Yu gasped and stammered, "Is this... is this... over?"
Xun You and Jia Xu were still staring blankly at Cheng Yu, who looked like a tired dog, but suddenly they heard Lu Yan say it's done?
"It's over?"
"This news was passed on like this???"
Xun You and Jia Xu looked at Lu Yan in disbelief, as if he had heard the most incredible thing in the world.
"Yes, it has been passed on." Lu Yan replied with an enigmatic smile.
"But... we didn't see anyone coming to get the news!" When Xun You said this, he suddenly remembered Cheng Yu's dance-like movements just now...
Just then, a gust of night wind blew by, and Xun You couldn't help but feel a chill on his back. "Could it be that you, Lu Qiaoqi, sent the ghosts and gods to take away the letter?"
"You can't say anything, but you are so powerful and so powerful." Lu Yan said with a righteous look on his face.
"Then what is going on???" Jia Xu felt like he was being driven crazy by Lu Yan, "Lu Qiaoqi, can you tell us directly how you did this?"
"Want to know?" Lu Yan asked while maintaining 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, an angry shout suddenly came from behind Lu Yan: "Lu Yan! If I hadn't been able to beat you, you would never have been able to walk around without food today!!!"
"Keep your voice down! Don't let the enemy hear it!" Xun You quickly grabbed Cheng Yu.
Seeing Cheng Yu covering his chest angrily, Xun You quickly comforted him: "Why are you so anxious! If Lu Yan didn't tell us, Chen Liu still has Guo Jia!!!"
Cheng Yu suddenly said after hearing this: "Ah! That's right! Fengxiao is also the leader of the shadow guard, he must know the secret here! After we go back, we will find Guo Jia first. We must find out how Lu Yan broke the news tonight
Pass it on!"
"It will be fine after I go back, but what should I do tonight?" Jia Xu rubbed her temples and said with a wry smile: "I feel like it will be difficult for me to get a good night's sleep these days..."
"Ah!!! Damn Lu Changsheng!" Cheng Yu gritted his teeth and said, "I don't want to... I don't want to anymore... It's weird if I don't want to!"
Lu Yan listened to the wailing behind him, a smile appeared on his lips again, and said to himself: "Oh! I am destined to have no sleep tonight..."
...
The next day, while Lei Bo and others were plotting in a remote room, 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 Shadow Guard leader.
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 to the sky lantern, Zhao Yun rode back to the camp and handed the letter to Lu Yan.
The general content of the letter is: Tomorrow at midnight, Lei Bo will ask someone to raise a fire as a signal, and then he will personally open the west city gate with his confidants.
But they only have a stick of incense at most, and Ji Ling will definitely arrive with his army after getting the news.
In the past two days, Ji Ling has been monitoring Lei Bo more and more tightly. They have one and only one chance, and hope that Cao Cao will not betray their trust.
When Lu Yan placed the letter in front of Boss Cao and the three counselors with thick dark circles under their eyes, the entire Chinese army tent became eerily quiet.
"Is it possible that Mr. Lu can really control ghosts and gods??" Cao Cao was shocked when he looked at Lei Bo's reply on the desk. But only for a moment, Cao Cao felt relieved and said: "Mr. Lu is a cultivator after all.
As a person, some methods of driving ghosts and gods are actually not so unacceptable... Well... I should still take the initiative to enhance my feelings towards him."
After a long time, Cao Cao broke the calm and said, "Mr. Lu, how did you do it?"
Lu Yan chuckled, glanced at Cheng Yu and others, but did not answer.
Under the angry looks of Cheng Yu, Xun You and Jia Xu, Cao Cao said helplessly: "Since we have made a plan, let's act according to it tonight!"
"Here!" Lu Yan clasped his fists and Shi Ran walked out of the Chinese army's tent, leaving Cheng Yu and others to tell Cao Cao that Lu Yan was retaliating against them...
Just after midnight at night, a blaze of fire lit up at the west gate.
Soon after the fire came on,
There was a crunching and grinding sound at the west city gate!
Immediately, the suspension bridge outside the city gate was also lowered by the trusted soldiers brought by Lei Bo. The indestructible Shouchun City was like an undefended woman at this moment, opening its arms to welcome Lao Cao's attack!
Upon seeing this, Cao Cao immediately ordered before the suspension bridge was completely lowered: "Zhao Yun, Cao Chun, and the cavalry enter the city first. They must intercept Yuan's army and build a military formation behind Wei's army!!"
"A certain general takes orders!"
Not far from the west city gate, the cavalry who had been waiting quietly in the darkness for a long time took action.
"Boom!" The sound of horse hooves boomed!
The cavalry began to charge. When Zhao Yun and Cao Chun led the cavalry to the suspension bridge, the suspension bridge happened to have completely landed.
Behind the cavalry were the Beiwei Army, the most powerful offensive and defensive forces led by Taishi Ci and Dian Wei; behind and on both wings of the Beiwei Army were the Tiger Guards led by Xu Chu and the Yingchuan infantry led by Zhang Liao and Cao Ren.
Ji Ling was awakened by a thunderous sound. At this time, a messenger came to report: "Report! General! The West City Gate... The West City Gate has been opened by General Lei Bo!!!"
"What, Lei Bo... West City Gate!" Ji Ling picked up the collar of the messenger and shouted angrily: "Say it again!!!"
"General Lei Bo opened the west city gate to welcome Cao Cao's army into the city! Everything you say is true, general, please respond in time!"
At this moment, Ji Ling felt dizzy and his head was buzzing. He didn't hear a word of what the messenger said later.
When Ji Ling came back to his senses, he felt weak all over and his heart was full of despair, "It's over...Cao Cao is coming in!"
