Knowing that he had found a clue to take off his flowers, Song Gu Xi suddenly came to his senses.

Li Shenghe took out a map, on which there was the general topography of the Yaksha country, and it was not clear further north.

Song Guxi listened carefully to Li Shenghe's tactics, only felt a pain in his stomach, couldn't help frowning, and snorted lightly: "Hmm......"

Seeing this, Li Shenghe hurriedly said: "If the commander is unwell, you can rest first, and discuss it later, forgive that grandson can't run away!" ”

Song Guxi touched the bulging lower abdomen, and said with a smile: "Good son, my mother will save you military merits, don't make trouble!" ”

After finishing speaking, he pointed to the position marked on the map, and said: "If we attack head-on, the enemy army will inevitably flee north, where there is a vast frozen plain, I am afraid that it will be difficult to cut the grass and eradicate the roots, so let him run away." ”

Li Shenghe also had this intention, and said: "It's cold and snowy, and it's very difficult to march, if this dog keeps running, we can't keep chasing it." ”

Song Gu Xi felt a little tired, so he lay back in his chair and said, "Don't be in a hurry, you have to think of a perfect plan." ”

Li Shenghe bowed his head and said, "Please command the envoy to command!" ”

Song Gu closed his eyes and recuperated, and after a long time, he said: "Relying on our own troops, it is difficult to wipe them all out, it's time to use the power of the imperial court." ”

Li Shenghe understood and said: "Your Majesty will personally go back to Beijing and ask the imperial court to send more soldiers and horses!" ”

"It's too far, go back, and wait for the results of the court discussions, and you will run away long ago!"

"That'...... What do you mean? ”

Song Gu Xi pondered for a moment and said: "Before going to sea, the emperor promised me that if there is news from the Tatar Ministry, you can turn to Mohewei for help, you can take my token to Mohewei now, and find the Julu Marquis to discuss the dispatch of troops." ”

"Yes!"

Julu Hou Jingyuan was stationed at the mouth of the Mohe River, including all the range of the Wudi River Guards set up during the Yongle period, as well as the entire Sakhalin Island.

Li Shenghe set out by boat from Kamchatka and arrived at the Mohewei command post five days later.

A city had been built here to hold the pass leading from the north of the river to Liaodong, and it would be difficult for the Tatars to return to the Central Plains.

Jing Yuan saw the token of the commander of Beishanwei, but his expression was a little strange.

At the beginning, the imperial court did send a newspaper from the palace, and the newly established Beishanwei was the closest to Mohewei, where he was located, so he naturally had to pay special attention to it.

However, when he learned that the commander of the Beishan Guard turned out to be a woman, it was very intriguing.

I don't know who came out of the capital to say that this person is actually the emperor's old friend......

These are not the point, the problem now is that the traces of the Tatar Department have been found, when the Northern Expedition was made, Jing Yuan had led the soldiers and horses of the East Road to directly harden the Tatar Department and beat it to the ground.

Since Tokhtobuhua fled to the far north with the remnants of his defeated army, the Tatar tribe is long gone, and there is only a tribe of 10,000 people left, and it is easy to kill him, the question is how to cut the grass and eradicate the roots.

Otherwise, you will drive people away today and come back tomorrow to find trouble, and the cycle will be repeated, and it will be annoying.

Jing Yuan picked up the map and looked at it carefully, and said: "If the troops are sent from two directions, the other party will definitely escape, and this time he must not leave a way back." ”

Li Shenghe bowed his head and said, "Our Song commander also plans to do the same, but the terrain of the extreme north is open, and if you want to encircle and annihilate it, you need to send a large number of troops. ”

"Exactly!"

Jing Yuan's face was heavy, and he said: "With the strength of you and my two guards, I'm afraid it's not enough, if you add Duoyan Sanwei......"

He made a few gestures on the map, nodded and said, "Well, if you divide your troops together with Duoyan Sanwei, you will definitely be able to teach him that there is no way to escape!" ”

Li Shenghe hurriedly said: "I also ask the Hou Ye to summon Duoyan Sanwei to discuss the matter of sending troops!" ”

Jing Yuan shook his head slowly, and said: "The emperor once instructed that if Beishanwei needs support, Benhou can directly send troops without asking for instructions, but if you want to mobilize the three guards at the same time, you must go to the imperial court!" ”

Li Shenghe also reacted at this time, Beishanwei's privilege to act independently in the Ghost Country was specially approved by the emperor, and now, it is necessary to use soldiers and horses on a large scale, and it must be approved by the imperial court, so why do you forget about this stubble.

Merely......

He hesitated for a moment and said: "I will go to Beijing for thousands of miles, and I will send it to the imperial court, and it will take at least two months to go back and forth. ”

Jing Yuan smiled and said, "It won't take that long, just send a telegram." ”

Li Shenghe was a little stunned and asked, "Telegraph...... What is it? ”

"The telegraph is ......"

Jing Yuan suddenly thought that Kitayama Wei should not have seen a telegraph before.

"You are overseas all the year round, and you don't know that this telegram is a new thing researched by the Academy of Sciences, and it needs to lay a line.

Nowadays, the territory of Daming is expanding rapidly, and information transmission has become a big problem.

Although there are railways now, they cannot reach all corners, and the strength of railways lies in their transportation capacity, not in the transmission of information.

Once the front line encounters a war, it is necessary to transmit the information to the Beijing division as soon as possible, and in the past, it was just that, but now the territory is expanding again and again, to the north to the difficult river, to the south there is no boundary, and it is counted as going to sea.

In such a territory, if there is a war on the front line, how can information be transmitted quickly?

In response to this problem, Zhu Qizhen had a headache for a long time, so he ordered the Academy of Sciences to develop a telephone, but the telephone was too complicated, and the key problem has been difficult to solve.

Although this thing is not as convenient as the telephone, at that time, it was already an artifact.

As a result, Zhu Qizhen immediately issued an order to lay telegraph lines in all major state capitals and health offices.

It's just that the telegraph at this time is still very primitive, the failure rate is relatively high, and the technology of the wire is not mature enough, the longer the distance of laying, the more easily damaged, once there is a problem, a large number of technical personnel are needed to check along the line, which is time-consuming and labor-intensive.

Therefore, at the suggestion of Tong Xuan and others, the imperial court adopted the method of sectional laying and set up telegraph stations in important state capitals and guard stations.

These stations act like courier shops, passing information from one station to the next until they reach their destination.

For example, if you send a telegram from Mohewei to Jingshi, you need to send the telegram to Haixiwei Station first, and after Haixiwei Station accepts it, you must first check the coded font size of the telegram header.

Each station will have a code, and the code of all stations will be included in the password book.

When Heixiwei saw that the encoding number of the telegram header was Jingshi, he would not decipher the message, but would copy a copy for archival purposes, and then send the original message to the next station.

The next stop was repeated until the message arrived in Beijing.

More than 5,000 miles from Mohewei to Beijing, seventeen telegraph stations were set up on the way, and even some places were not important towns, and there were no guards stationed, just because the strategic location of Mohewei was too critical, the imperial court specially issued an order to open up a line for it.

Li Shenghe didn't know what a telegram was, and he didn't believe that the distance of thousands of miles could be reached in half a day, and the people who could say this were either immortals or crazy!

However, he looked carefully at the giant deer marquis in front of him, and there were no signs of madness......

I secretly pinched my thighs again, it felt very real, not a dream.

"Without further ado, Ben Hou will play immediately!"

Jing Yuan instructed someone to bring a pen and paper and write the message himself.

Since the siege of Mohewei, the Tatars have occasionally come to harass with small cavalry, but the main force has never appeared, and he is certainly not willing to give up this excellent opportunity.

After a while, he put down the pen and paper and beckoned: "Come on, go and send a report quickly!" ”

"Yes!"

Immediately, a special sender took the message away, and the text had to be converted into numbers before it could be sent.

Li Shenghe took the opportunity to take a look, but saw that there were only a dozen or so words, and his expression was even more dazed.

This is a note written to the emperor, at least politely, with a beginning, for example: How are you the emperor, have you eaten, and how are you doing recently......

After the polite words, then the narrative.

At this time, it is necessary to be as detailed as possible, because it is not easy to send a trip from afar, if it is because some details are not clear, the emperor asks, and he has to re-submit the book, which is too troublesome.

However, on the piece of paper that had just been taken, there were only a dozen or so words.

Basically: Go find Lao Mo, I want to eat fish!

Such a sentence, where is this presented to the emperor, it is clearly to give orders to his subordinates!

Seeing that his entire face was almost distorted, Jing Yuan asked puzzledly, "Is there any problem?" ”

"The telegram that Hou Ye just mentioned...... What is it, exactly? ”

Jing Yuan smiled, then beckoned to the side, and immediately a scribe stepped forward.

"Lao Cao, you take Li Tongzhi to the telegraph station!"

"Yes!"

The scribe surnamed Cao turned to look at Li Shenghe and said, "Li Tongzhi, please come here!" ”

Li Shenghe retreated and followed the scribe to a separate barracks.

At the doorway, a sign was hung "Telegraph Station", and strangely enough, not far away stood a wooden stake, and two lacquered threads were pulled out of the barracks, tied to the top of the column, and then extended south to the next post, and then continued south, as far as the eye could see, with no end in sight.

Cao Shuzhi stretched out his hand and signaled: "Li Tongzhi, this is Mohewei's telegraph station, please!" ”

Li Shenghe looked up, but saw a sign erected at the door of the barracks, with eight big characters written on it:

Military stronghold, forbidden to approach!

"This ......"

Seeing his hesitant appearance, Cao Shushi said, "Master Hou has specially ordered, you can enter!" ”

"That's good!"

Li Shenghe walked into the barracks and saw another scribe, holding a note written by Fang Cai Jingyuan in his left hand, and a book of word measurement in his right hand, while flipping through it, he was recording something.

Cao explained: "This is the first step in generating electricity, which is to convert the message into a digital first. ”

Li Shenghe scratched his head and asked, "How to transform?" ”

"The conversion of messages requires the use of a special code book, the principle of which is more complicated, the lower official will explain to you later, you see, the dispatcher is ready to send the report!"

Li Shenghe followed the sound and looked, and sure enough, the scribe just now was already fiddling in front of an instrument.

Didi ......

The instrument made a rhythmic dripping sound, but I didn't know what it meant.

Cao Shuzhi knew that Li Shenghe had seen the telegraph for the first time and did not understand anything, so he explained: "This is debugging, and the other party needs to respond to the message to verify whether the line is unblocked and ensure that the sent message can be received by the other party." ”

Li Shenghe nodded as if he didn't understand, at this time he saw everything fresh, although he couldn't understand it for a while, but he felt ...... Tall and tall......

"The nearest telegraph station is the Herciewe station, about three hundred miles away."

"Three hundred miles?"

Li Shenghe frowned, three hundred miles away, even if it was the fastest horse, it would take a whole day to make a round trip, but he didn't know how this telegram delivered the news......

Didi ......

The telegraph was silent for a while, and suddenly the sound came again.

"Hey, it's ringing, it's ringing......"

Li Shenghe shouted, but saw that the people guarding the telegraph were listening intently, and while listening, he also took a pen to transcribe.

Scribe Cao smiled and said, "This is the other party's response." ”

"So fast?"

Li Shenghe was shocked, it was less than a cup of tea, and the two sides exchanged information?

Three hundred miles!

The fastest official document in the imperial court, known as the Six Hundred Miles Expedited!

The so-called 600-mile expedited is to require the fastest speed and shortest time to deliver the official documents to the capital.

Generally speaking, this minimum time cannot exceed one day!

The messenger could not rest during the whole process, changed horses without changing people in the middle of the process, and ate and drank Lazar all on the horse.

Such an urgent paperwork is basically the result of running a dead horse.

It is even common for the messenger to die of overwork after delivering the message to its destination.

Therefore, unless it is absolutely necessary, the imperial court will not use the six-hundred-mile expedited delivery.

What are you pressing, it only takes a cup of tea, and it's over?

Li Shenghe didn't understand that such an important court event, in order to deliver news, I don't know how many people and horses had to be exhausted to death, how could it become a leisurely errand for drinking tea and chatting with you?

Cao Shuzhi knew what he was thinking when he looked at his expression.

"Li Tongzhi, look at the pillar outside."

Li Shenghe looked outside, nodded, and asked, "How?" ”

"This is the wire, and the message just sent is transmitted along these lines."

"If this thing is not as thin as it is, can it still contain paperwork?"

"It's not a paperwork, it's a message!"

Li Shenghe asked again: "Isn't the message a document?" ”

Scribe Cao had to explain: "It's a document, but it's not the kind of document you think!" ”

"What kind of paperwork is that?"

"It's a compiled and transformed document."

"The content has changed?"

"Not really."

Li Shenghe still couldn't figure it out, and said, "Speaking of which, isn't it still a paperwork?" What's the difference? ”

"The difference is huge......"

Scribe Cao sorted out his thoughts, and then started from the beginning.
