With the latest batch of bayberry on the market, the Hanyang canning factory is already busy. In addition to personally leading people to Chang'an, Zhang De also asked Cao Xian about the number www.biquge.info of commonly used words nowadays.

He's not a word expert, but he needs a word expert.

"This is the three-revised version of the "Word Code"."

Cao Xian didn't feel tired, he was easy to write about. Whether it is the newly revised 39 phonetic "Original Sound Training", or the 36 Zhuyin Persian, they are all very slippery.

Lao Zhang needs him because of the signal.

Relying solely on carrier pigeons to deliver messages quickly can be a bit costly. Every year, regardless of the number of qualified or unqualified pigeons, we must cultivate fifty or sixty thousand, which is okay in the next few years, but with the flowering of the local economy of Datang, the growth of the number of pigeons is not doubled, but more than ten times dozens of times.

A successful delivery of a message requires at least twenty carrier pigeons, and even fifty in desert areas. If there are five relay deliveries, it is a three-digit number of pigeons.

In view of this, Lao Zhang decided to make a set of signals. With the telescope, it can be designed as a fixed-point signal transfer station along official roads, tracks, straight roads, relaxation roads, and canals.

The signal machine between the Jingluo plate and rail has been tested before, with one station for five miles, and each station has a group of three times three signal groups. Each signal group has a certain color shape for easy observation.

For example, in order to tell Luoyang to purchase 100 stone millet seeds, then the first group expresses "procurement", the second group expresses "100 stones", and the third group expresses "millet seeds".

From Chang'an to Luoyang, it only takes an hour to deliver such a message and then give feedback. This is still a case where the unit on duty has no experience.

The most exciting thing is that if you use a glass lampshade as a signal group, except for heavy rainstorms and snowy days, even cloudy nights, it will not affect the messaging, and it will be just as fast.

This experiment aroused many people's interest, and Hou Junji, the secretary of the Ministry of Officials, as the former secretary of the military department, immediately suggested that the imperial court establish such units on the main border supply routes.

In this era, the Tang Army can react quickly to any turmoil in the frontier area, and then quickly suppress the lawbreakers.

The most important point of Zhang De's experiment is to compress the reaction time from "months" to "days".

For example, Liaodong's conquest of the Khitan, at that time, the Dingxiang Governor's Mansion could first conceal a vote from the imperial court, and then report it. But with this signal system, first of all, the matter of the Khitan rebellion will not be delayed because of the cover of the Dingxiang Governor's Office. As long as the news has passed through Youzhou, it will be so fast, and it will take six or seven days for the imperial court to issue instructions.

After Hou Junji's suggestion, Li Jing, who has been cultivating immortals, cultivating Buddhas and repairing cars at home, also thinks that this is a very useful thing, which is more efficient than the post station.

As an emperor with excellent military and political skills, Li Dong did not plan to discuss this matter with most of the waste Qingliu who did not understand military affairs in the foreign courts, and ordered the Ministry of Civil Affairs to make a budget first, and first to do the route of the Anbei Metropolitan Protectorate.

In addition to the imperial court, Zhang De's experiment made the eyes of the local tyrants of the two capitals brighten up. Regardless of Chang'an or Luoyang, the concept of "business opportunities" has changed three times a day. In the past, if you knew in advance that the production of mulberry silkworms in the south of the Yangtze River was reduced, you could do it in the Central Plains one month in advance.

But now it can't be done, and it lasts for ten days.

With this signaling system, that's a day.

However, not everyone can play with this system, there is no pre-set "code book", and there is a "Jindan-level code book" specially refined by a text expert like Cao Xian, and those local tyrants in the foundation building period are not even allowed to peep into the doorway.

In the end, it becomes a mathematical problem again.

So the disciples of the true transmission of "Wang Xue" put on the black pot again and probed the thunder for Lao Zhang.

"Ah...... I miss Nuoban bricks, big brother is okay, I don't have high requirements. ”

The runway view gave incense to the god who didn't know which one, Lao Zhang was full of emotion, this day ...... It's too hard.

Everywhere you look is a fair lady and a fair young woman, but ...... I want to give the middle finger to my coquettish girlfriend while opening up the wasteland when I was an undergraduate, that's the life of a person.

Taking a deep breath, Lao Zhang silently said in his heart: For the tribe!

Then he held his head high, ran to Anping, who was in the cool, and kneaded his shoulders, and then asked, "Zhiniang, when will you leave for Chang'an?" ”

"Let's talk about it."

Li Zhi'er lifted her blindfold and stared at Lao Zhang suspiciously, "Zhang Lang, are you looking forward to the concubine returning to Chang'an?" ”

"Nothing!"

Jiangnan Tugou, who immediately denied it, smiled, "What I mean is that since the emperor said that he is unwell, you will go back to accompany him, and by the way, help me inquire about the news......"

The news between the noblewomen is sometimes extraordinarily well-informed. To put it bluntly, Lao Zhang knows that Li Zhi'er has a good relationship with Empress Changsun, although with Li Zhier's IQ, she is definitely not the opponent of Empress Changsun, but as long as she hears any news, analyzes and analyzes, she can still know something.

Besides, Empress Eldest Sun may have hinted at something.

"Hmph, don't you know when I do? That lady Xiao, I'm afraid that the concubine will walk on the front foot, and you will climb on her warm couch on the back foot and say something intimate and nice to coax her. That woman is also a fool, being a deep house woman, that's all. ”

“……”

It's all what and whatever!

"It's Cui Mingyue, smart Bing Xue, no wonder your government office still has her. Brother Yu has a secretary and supervisor, you are the secretariat? The secretary girl is no worse than the secretary of Chang'an. ”

"Zhiniang, you are very insightful."

Lao Zhang Yin and Yang rubbed his shoulders weirdly, and squinted at her, "From now on, I, the Changshi Mansion, have something to do, and it's okay...... Ahem, let's talk about returning to Beijing first, you can help me inquire and see if the emperor plans to start moving the capital this year. ”

"Didn't Zhang Lang just say that the emperor was unwell and asked Yu to go back to accompany him? Isn't this an inquiry? How? Now that it has changed again, it is still necessary to inquire about the big matter of moving the capital. The little girl didn't dare to be it. ”

Hey......

The eldest son was born to her, she is arrogant, she is domineering.

But Lao Zhang is not out of the question.

"I don't know what Chenguang is?"

The sweaty Anping leaned on Lao Zhang's chest, the silk on the soft collapse was covered at will, and the bamboo leaves were shuttled outside, Zhang De leaned on the cotton leather pillow, and responded a little tiredly: "What do you care about Chenguang, what do you want to eat at night?" ”

"And I slept for a while, and I didn't want to eat anything. When I go back to Chang'an, I will make up for it. ”

After that, Li Zhier leaned sideways, lazily shrunk in her arms, and after a while, she fell asleep.

Jiangnan Tugou has a strong spirit, with a look of disdain, and secretly said in his heart: Can Lao Tzu still cure you?

It's a pity that engineering dogs don't smoke, otherwise one can be worthy of the pride at this moment.
