Daxing City (Chang 'an City) was rectangular in shape. It was 9721 meters long from east to west, 8652 meters wide from north to south, and 36.7 kilometers in circumference.
Daxing Palace, which was located in the center, was only about 6 kilometers away from the edge of the city.
Guo Yan and Li Jing were galloping at top speed.
One went south while the other went north.
The 100,000 imperial guards were stationed in the South Camp and the North Camp respectively.
Guo Yan and Li Jing were excited.
They had already learned how to use the walkie-talkie to communicate.
They were going to the north and south camps to see if they could talk to Yang Guang directly.
Guo Yan and Li Jing had never seen such a magical thing before.
Wasn't this the legendary Thousand Mile Voice Transmission?
Li Jing and Guo Yan arrived at the north and south camps respectively.
Li Jing carefully put the walkie-talkie to his mouth.""Your Majesty, can Your Majesty hear me? I am Li Jing, I have arrived at the South Camp.”
As soon as he finished speaking.
Yang Guang's voice came from the walkie-talkie,""Li Jing, I heard it. Where is Guo Yan?”
Guo Yan's excited voice came from the walkie-talkie again,""Your Majesty, Li Jing, I heard you!”
"Is the voice clear?" Yang Guang asked again.”
"It was exceptionally clear. We heard it very clearly." Li Jing and Guo Yan answered at the same time.”
Yang Guang nodded. This was within his expectations.
With the walkie-talkie, the palace would be safer.
As long as there was any movement in the city, he could directly transfer troops into the palace through the walkie-talkie.
This was why he took out the walkie-talkie first.
Safety was greater than the sky.
"Li Jing will continue to ride south while Guo Yan will continue to ride north.
Call once every ten miles. I want to see where the limit is.”
"Yes!"
Guo Yan and Li Jing continued to ride their horses.
Just as Yang Guang said, they would call each other every ten miles.
Guo Yan and Li Jing were more than 50 kilometers away from each other.
There was already some noise in their voice transmission.
As for Yang Guang, who was in the middle, his conversation with the two of them was still very clear.
Yang Guang also understood that this 50W walkie-talkie had a communication distance of about 50 kilometers.
In the modern era, where electromagnetic pollution was severe, it was exaggerated. In the Great Sui Dynasty, where pollution was zero, communication within a hundred miles was truly realized.
"Come back!"
An hour later, Guo Yan and Li Jing returned to the palace.
The two of them could not hide the shock on their faces.
"Li Jing, where were you just now?" Guo Yan asked.”
" I can already see the city walls of Chang 'an County," Li Jing replied." I've already stepped into the territory of Chang' an County."”
" I'm already in Jingyang County," Guo Yan muttered to himself." Jingyang County is more than a hundred miles away from Chang 'an County. Although it's a little blurry, I can still hear your voice!"”
Li Jing and Guo Yan raised their heads at the same time and saw Yang Guang's calm face.
It was as if this was how it should be.
Li Jing and Guo Yan looked at each other and saw the shock in each other's eyes.
To be able to take out such a miraculous item, His Majesty was unfathomable!
Yang Guang smiled and asked,"You've all experienced the effect of this walkie-talkie. Do you two beloved ministers have any thoughts?"”
Guo Yan's eyes lit up and he said,""Your Majesty, this walkie-talkie is too magical. With this thing, you can personally command 100,000 Imperial Guards.”
"Even if I am in the military camp, I can receive His Majesty's edict as soon as possible!”
"Not bad, interesting!"
Yang Guang nodded. What Guo Yan said was also his original intention.
He took out his walkie-talkie to better control the 100,000 imperial guards.
"Li Jing, what do you think…"
Li Jing's brows were originally tightly furrowed, but after hearing Yang Guang's question, he suddenly relaxed.
"Your Majesty," he knelt down again,"I just thought of an immature plan. I don't know if it can be implemented."”
Yang Guang smiled slightly,"Here, no matter what you think, it doesn't matter."”
Li Jing sorted out his thoughts and said to Yang Guang,"Your Majesty, our Great Sui has a vast territory. The capital is thousands of miles away from the border.”
"The most inconvenient thing about such a long distance is communication.”
"If there is a war at the border, the generals guarding the border must pass the news to the capital. Even if there is a courier station, the news will reach the capital after ten days.”
"The capital has received an urgent report from the border to calculate the situation of the troops of the various prefectures, and then inform the various prefectures to gather their troops.
From the time the various prefectures received the decree to the time they gathered their troops and sent them to the border, the entire process would take at least a month!”
"In other words, the soldiers at the border will have to endure the enemy's fierce attacks for a month!”
"In this month, our Great Sui soldiers will suffer heavy casualties!”
Speaking of this, Li Jing looked at Yang Guang with some worry, worried that he would arouse Yang Guang's disgust.
However, Yang Guang nodded and encouraged him,"Well said, continue."”
Li Jing suddenly regained his confidence and continued to speak passionately,"I just witnessed the wonders of the walkie-talkie, so I have an idea.”
"This kind of walkie-talkie can reach up to a hundred miles. Should we build a relay station every hundred miles for communication?”
"From the capital to the border, there are at most thirty relay stations.”
"When our courier stations spread throughout the various prefectures and counties, the entire Great Sui Dynasty was connected like a spider web.”
"Once a war breaks out at the border, the communication relay station will use word of mouth to send the news back to the capital in less than two hours!”
"Your Majesty can then calmly dispatch the prefectural soldiers of the various prefectures and counties to quickly reinforce the border.”
"The county closest to the border can be reached in half a day. Once the communication network is established, the combat ability of our Great Sui army can be increased by 10 times!”
Li Jing clenched his fists in excitement.
Guo Yan's eyes grew brighter and brighter as he looked at Li Jing with admiration.
No wonder His Majesty valued this kid so much. He really had some skills.
Yang Guang also felt gratified.
Li Jing was worthy of being the Great Tang's God of War. Seeing the effect of the walkie-talkie, he immediately thought of how to use it in the frontier and maximize its ability.
Seeing Li Jing's expectant gaze, Yang Guang smiled slightly,""My dear minister, your vision is unique and your idea is very good. As you said, once you cut it into a communication network, the mobilization efficiency of our Great Sui army will increase by ten times.”
"Your Majesty, then…" Li Jing's eyes lit up.
" We need to build a communication network," Yang Guang said slowly." But it's not the kind of communication stations that you're talking about. It's just word of mouth…"
"I have a way to let the capital and the border have a direct dialogue in the future!”
