Chapter 4161: Gifts again!
"In addition, if you have finished using Xia Jian, you must replenish it in time. Otherwise, if I subpoena, you don't know!" Cheng Yu reminded.
If Jane is not here, then his messenger will fail. And he can easily judge whether the foreign king has received the message based on whether the upper hand of Jane is broken.
As long as the foreign king looked at Yu Jian, the Yu Jian in his hand would also be broken. If the foreign king did not look at the jade Jane, the jade Jane on his hand would remain intact until the foreign king looked at the Jane and then broke.
However, the jade briefing is also time-limited. If the other party does not view the jade briefing for more than twelve hours, the content on the jade briefing will disappear and can be reused.
"I understand!" The foreigner nodded again and quickly put the jade Jane away.
This is a good thing. With this thing, you don't have to worry about not having enough jade Jane anymore. When he goes back, he will make dozens of them for future use.
"Master, you only give the foreigner such a good thing, isn't it unfair?" Luo Keya saw the foreigner excitedly put away Yu Jian, and she was also envious.
The foreigner showed them the use of Jade Jane, so she also knew that this Jade Jane was very practical.
And if this time it wasn't because the jade Jane was in the hands of the foreign king, how could the foreign king tell Cheng Yu at any time, and how did the foreign king learn about Cheng Yu's situation?
So this is all thanks to Yu Jian, she naturally hopes to have such a good thing.
"What do you want this for?" Cheng Yu laughed.
"If only the foreign king had this thing, in case the foreign king had to stay in the Baiyang foreign dynasty in the future, but we left the Baiyang foreign dynasty with people and horses, then how would we report to the master if we did not have this jade Jane What about our situation? "Rocoya said.
Yujian is the best method of communication she has ever seen. Of course, she also hopes that she can use this method to communicate.
"It's the same!" Cheng Yu thought for a while, and seemed to do the same, and then said, "Let's do this, I will also prepare a set of communication jade for each of your elders, is this always possible?"
"Really?" Rocoya was overjoyed, and it would be better if each of their principal elders had a set of communications.
"In order to ensure the concealment of the content of these jade bamboo slips, all the jade bamboo slips are only transmitted from top to bottom, one to one.
Therefore, the jade bamboo slips I have given you, except for the communication between us, must not allow the third person to have the same jade bamboo slips, otherwise the messaging between us will be seen by this third person. Cheng Yu was so happy to see Luo Keya, but he must remind the other party well.
This is a very important key. Each set of messaging matrix is different. However, these messaging matrices are very easy to change, so you can make a new set of messaging jade with a slight change. Such changes Only he knew it, and he would not coincide with other people's messenger Yu Jian.
"Master please rest assured that I will tell them well at that time." Rocoya said cheerfully.
"Anyway, I have to prepare so many sets, then I will give you a big gift!" Cheng Yu thought about it, and thought that something might be a good thing for them, so he said.
"What a gift?" Both Wang and Rocoya looked forward to it!
"I have already said that under normal circumstances, for the sake of confidentiality, these communication jade Jane are divided into one-to-one transmission.
However, this is just one of the messaging jade bamboo slips. There are some more complicated jade bamboo slips. "Cheng Yu said.
"Master's point, is there still many to many jade Jane?" Said the foreigner in front of him.
"Almost, but a one-to-many jade Jane!" Cheng Yu said.
"One-to-many? Please ask the master to elaborate!" Said the foreigner.
"That's it. I'll give you this set of jade slips. You can use them to summon the jade slips with the guards at the borders outside Baiyang." Cheng Yu said.
"Survey to the border guards? But I have nine border towns in Baiyang's foreign dynasty. Could this master's special set of jade jade Jane be a pair of nines?" The foreigner wondered.
"If this is the case, the foreign king is holding Jane, and the other nine border towns are not holding Jane!" Luo Keya said.
"This is indeed possible. If all nine of them hold Jane and they send you a message, you can all see it.
It's just that, because the jade bamboo slips in their hands are the same, if you give an order to one of the cities, the other eight border cities will also see it.
If it's not important information, then it's okay, but in case it can only be known to that city? Isn't it a big deal? Cheng Yu explained.
"That master's point, can your special set of jade Jane also send a message to one of the border towns alone?" The foreigner asked expectantly.
"Yes, that's why I want to give you this set of jade Jane. If anyone in the border city enters the Baiyang dynasty in the future, you can grasp the latest news as soon as possible. I think this is right for you. I'm all good! "Cheng Yu said.
"If there is such a jade Jane, of course, it can't be better!" Said Foreign Minister Xin Xin with joy.
Just like when the special envoys entered Baiyang's foreign dynasty before, his messenger rushed to Baiyang's foreign dynasty as quickly as possible.
But even so, it took half a month. After he received the news, the envoys arrived half a month later.
If nothing special happens, this kind of communication is fine.
But if the other party is leading the army, then this time may not be of much use.
And ~ www.readwn.com ~ It is also more risky to use messenger. Sometimes messenger will be found, and if the messenger fails, the consequences are even more unimaginable.
If each of the border towns now has its own different messaging jade, then there is no need to worry about any delay in any news.
More importantly, if he has any instructions, he can pass them to the defenders in the fastest way.
For example, if a foreign enemy strikes, which border town he wants to immediately close the city, if he uses a messenger, the news will be a round trip once and for all. The border town closest to Baiyang's foreign dynasty will also waste a month.
Really when this order was passed to that border town, the order had no effect. Perhaps their city was already unsustainable.
However, using such a jade Jane, not only can he immediately know that a foreign enemy is coming from the border city, but he can also order the defender to block the city immediately without any delay.
"But this set of jade slips is a bit cumbersome. I need some time to set up the matrix, so you may have to stay with me for a few days!" Cheng Yu said.
