Zhang Qian immediately asked the guards to bring pen and paper, wrote down the paperwork, and asked everyone: "If you still have anything to report to Your Highness, let's go together." Pen & Fun & Pavilion www.biquge.info so as not to trouble. ”

Li Guangdao: "That's all the Huns." Ask Your Highness what to do. ”

Zhang Qian added a few more words. Then I put the paperwork in a box. Sealed the mud, took out the seal letter and stamped it. before handing it over to Li Ying.

Li Ying smiled lightly: "It's too troublesome, you don't have to do it like this in the future." As he spoke, he took it and opened it directly, and took out the silk book inside.

Li Guang was dumbfounded: "You stinky boy, although you are engaged in intelligence, don't be so blatant." The parties are still standing here. ”

But isn't it, Zhang Qian stood to the side dumbfounded. Is there such a thing as you, in case this is some other secret letter, or even against you Li Ying, then it will be repaid.

Li Ying smiled faintly. He handed the silk book to a shadow under his hand. The shadow took the silk book and immediately ran up to the bell tower next to it. Immediately, there was a clanging bell from inside the bell tower.

Yuan Zhouzi was speechless: "Nonsense, what kind of bell is ringing at this time." It's still a random knock. What the hell? ”

Hong Zhong Da Lu, that's what he said. The sound of the bronze bell striking several thousand catties came out through the concentrated reflection of the wall of the bell tower. The sound is deep and penetrating. It's not a matter at all if it spreads out for dozens of miles. And the sound of the bell is long and short. There is a pause between the short and the long. Sometimes it's long and short, sometimes it's short. It rang for a long time.

And on the slope of a small village of the Dayue clan at the back of the Xiongnu barracks, a man was holding a crumpled note to smooth out the careful recording of the length and pause of the bell. From time to time, he looked around vigilantly.

Zhang Qian frowned, and hesitated: "Did you have a password with someone?" Replace words with bells. Pass it on. The man heard the bell dozens of miles away, and he understood the meaning of this? ”

Li Ying said with a smile: "Bo Wanghou is really smart. This method of information is painful enough to be given to me by His Highness himself. It can ensure the confidentiality of our Heavenly Dao. ”

Li Guang frowned and said, "You can hear it, and the Huns can hear it too." How is it foolproof? ”

Li Ying smiled: "What does it matter if he hears it, I don't know if the content and meaning are still in vain." For example, the two of us agreed that we would have to eat after three rings. When they heard these three sounds, they couldn't even think of eating. Besides, we can change it in a few days. It can be changed to three rings to drink water. Or maybe it's five rings to eat. Even if my uncle was caught and leaked secrets. But the next day, the code was changed again. In this way, we can ensure our confidentiality to the greatest extent. ”

Li Guang scolded angrily: "You have just been arrested, and your whole family has been arrested." ”

Li Ying smiled and said, "My whole family, doesn't that also include you, uncle?" ”

Zhang Qian groaned: "Good is good. But in this case, the one who rings the bell translates the words. And the person who records the bell should pay special attention. ”

Li Ying nodded: "Well, Your Highness has ordered." Those who ring the bell are not allowed to know the contents of the information. The interpreter is not allowed to touch the bell tower. And the people in the village who recorded the bells didn't know what they meant. All you need to do is record the bell and send it to His Highness. Even if it's intercepted. People only have dry eyes. ”

Zhang Qian nodded and said, "Good way." ”

Li Ying said with a smile: "Your Highness said that when this system becomes more accurate and huge, you will be equipped with special confidential personnel to manage the translation of this word into bells." At that time, each adult will have their own set of passwords. It also does not affect each other. Even if you want to sue your Highness for my black state, you will never know about it. ”

Li Guangyin smiled: "That's good." That's good. ”

As for it, it's just a simple Morse code. It's so strange? In the final analysis, this is the same as the flag or something, as long as the agreement is made and not told to others. It's not that complicated. It's not like the cracking codes mentioned on TV, which can be known by calculating with an abacus. Without a codebook, you can't do anything about breaking your head.

The intelligence easily bypassed the Xiongnu camp, passed through the entire Western Regions and was sent to Loulan, and arrived in the hands of Ruhua. Ruhua hurriedly sent it to Xue Qing and said, "Your Highness, the secret letter from Guan Pass." ”

Xue Qing is playing with a pitcher. An arrow was thrown out without even hitting the edge, and without raising his head, he said, "Read it." As he spoke, he picked up another arrow and aimed it.

Ruhua whispered: "It's a cipher letter." ”

Xue Qing was stunned: "That means that the pass has been discovered by the Huns and blocked, right?" ”

Ruhua said: "It should be." ”

Xue Qing nodded and said, "Go get the password book to translate." ”

Ruhua hurriedly opened the drawer and went out of the codebook. According to the above content, all the information of the secret letter was translated, and then it was respectfully handed to Xue Qing.

Xue Qing sighed and said, "Alas, this Li Tuo Ci is miserable enough. He replied to the past, saying that on behalf of the Emperor of the Han Dynasty, he would like to congratulate him on his succession to the throne. and ordered Zhang Qian to prepare a generous gift. In addition, since the pass was blocked by the Xiongnu. It is better to send Li Dare to the Great Moon Clan to rely on the lurking shadow to develop the Great Moon Clan's resistance force. Li Ying can help Li Totoci provide support and communicate information remotely. Well, that's it. ”

If the flower has translated the content, she will go out to deliver the letter. Xue Qing asked him to call Li Dang over by the way.

After Li Dare came over. Xue Qing said to him: "Do you remember when you were in North Korea at that time, you suggested that the palace use the Taishou Captain of the four counties to lead the big and small officials to sneak back and lead the Koreans to resist Wei Zheng?" ”

Li Dang nodded and said, "En." What's wrong. What is the matter of North Korea still on His Royal Highness's mind now? ”

Xue Qing rolled her eyes and said, "Who cares about North Korea." Something thousands of miles away. The main shrine is said to be the west. Now Da Dan Yu has discovered the angry Hun Pass. In addition, troops were stationed on the east side of the pass, which hindered the communication between the pass and the Otsutsuki clan. We can't bring the soldiers and civilians of the Otsuki Clan in. Therefore, according to the method of North Korea back then, a general can be sent to lead the shadow to develop underground resistance forces. You must know that the rule of the Xiongnu over the Da Yue clan was far more brutal than the rule of Wei Xiao over Korea. As long as they can provoke the Dayue people to rise up against the Huns one after another, they can set their backyards on fire. We can't let go of such a good thing. ”

Li Dare pointed to his nose and said, "Me? Is Your Highness going to send me? But you didn't mean that there were two generals under your command, one was sent by my father to guard the pass, waiting for the opportunity to move. The other is me, I want to stay in the Western Regions to do something. Sword, right. A sword with ease. Then if I go to the Otsutsuki clan, it will still become a nail. It's still unsightly.
