"Your Majesty, Your Majesty, I'm Li Junxian, and I'm outside the Mingde Gate now."

In the Lizheng Palace.

On the walkie-talkie in Li Shimin's hand, Li Junxian's voice came.

The voice was so clear that it seemed to be right in front of you.

"Jun Xian, continue south."

"Subordinates obey!"

Li Shimin's heart is beautiful, a magic weapon.

Now that he has a magic weapon in his hands, he finally has a magic weapon.

If you had this magic weapon in your hand when you were fighting the world, it would have been much more convenient, transmitting information and issuing military orders.

Thinking of this, Li Shimin thought that it was not too late to have this magic weapon now.

Qing Yama is one of Li Shimin's favorite horses, and it is deeply loved by Li Shimin for its speed.

In the Lizheng Palace, when the walkie-talkie rang again.

Li Junxian was already ten miles away from Chang'an City.

"Jun Xian, go all the way to Lantian County."

Li Shimin's eyes became more and more intense.

It is ten miles away from the south of Chang'an City, that is, from the Lizheng Palace, which is already twenty miles away.

At such a distance, the sound transmission device is still clearly audible.

How can Li Shimin not be excited? There are so many things that this magic weapon can do.

"Your Majesty, Your Majesty, I'm Li Junxian, and now I'm at the gate of the Yamen ...... Lantian County."

Call!

Call!

Call!

Not only Li Shimin gasped, but Empress Changsun and Princess Changle also gasped.

"Jun Xian, continue to go south and go to Zhongnan Mountain."

"Subordinates obey!"

Li Shimin put down the walkie-talkie in his hand, looked at Changle and said.

"Changle, Shangxian said that it can transmit sound for more than 20 miles, and now Li Junxian is already 50 miles away."

"Father, maybe there is a difference between a mile in the fairy world and a mile in the mortal world."

When Changle's voice landed, Li Shimin and Empress Changsun both nodded deeply.

Changle is right, this is also the most likely and best explanation.

At this moment, the shock in Li Junxian's heart is simply indescribable.

As the commander of the Hundred Cavalry Division, what kind of scene Li Junxian has never seen.

However, today's object in his hand, which is not yet the size of a palm, completely frightened Li Junxian.

The more Li Junxian thought about it, the more incredible he felt, his forehead was already covered with sweat on horseback.

Zhongnan Mountain is already close in front of you, and the Taoist hall on the mountain is also faintly visible.

"Your Majesty, Your Majesty, I'm Li Junxian, and I've arrived at the foot of Zhongnan Mountain now."

When the walkie-talkie on the table sounded Li Junxian's voice again.

Li Shimin really couldn't sit still.

Li Shimin picked up the walkie-talkie, stood up, took a deep breath, and pressed the call button on the right side.

"Jun Xian, Jun Xian, I ordered you to climb to the top of Zhongnan Mountain, and then pass the message to me."

"Subordinates obey!"

Li Junxian tied the green horse to the foot of the mountain, showed his skills, and went straight to the top of the mountain.

Li Junxian arrived at the top of Zhongnan Mountain, raised his eyes and looked at Chang'an City, and the entire Chang'an City was faintly visible.

Now, Your Majesty shouldn't be able to hear it.

Li Junxian wiped the sweat from his forehead and pressed the soft key on the right side.

"Your Majesty, Your Majesty, I am Li Junxian, and I have now arrived at the top of Zhongnan Mountain."

In the Lizheng Palace, Li Junxian's voice can be heard clearly on the walkie-talkie.

Li Shimin never thought that this sound transmission magic device could transmit sound for hundreds of miles.

Li Shimin's excited heart was pounding.

There are so many things that can be done in Baili Transsion.

Only ten such magic weapons are needed to deliver the message to Luoyang in tea time.

It only takes one person every 100 miles to deliver the message.

Then there are less than ten such Dharma instruments each, and they can transmit sound from the southwest to Yizhou and the southeast to Yangzhou.

I have to say, as the son of the Tang Dynasty.

Li Shimin's current pattern has indeed opened up.

It is an imperial pattern that looks at the world.

Li Shimin has a magnificent blueprint in his heart, that is, he raised his arms in the Taiji Hall.

The ten provincial highways, 358 state capitals, and 1,115 county offices in the Tang Dynasty can all receive their own dictates as soon as possible by means of voice transmission.

Moreover, once a natural or man-made disaster occurs in the place, or even an enemy army is attacking on the frontier, he Li Shimin can know everything about the world when he is in the palace.

In this way, the huge Datang is really convenient to manage.

It saves the local officials the long journey and tiring travel to the capital city of Chang'an to report on their work.

It also saves the messenger soldiers, the hard work of 800 miles of urgency, and the huge financial expenditure of post stations in various places.

Call!

Li Shimin took a deep breath, stared at Changle with fiery eyes, and spoke.

"Changle, my father begs you for something."

As the leader of the Tang Dynasty, and the father of Princess Changle.

Li Shimin's request not only frightened Princess Changle, but even Empress Changsun was instantly shocked.

"Why is this the father? Changle is the daughter of his father, but if he can do it, he will definitely do his best to help his father. ”

Changle's voice landed, and Li Shimin nodded with satisfaction.

Whether the plan he just envisioned can be realized, Li Shimin's greatest hope can only be Changle.

"Changle, my father still wants such a sound transmission magic device, 1,200 pieces."

Li Shimin's voice landed, and the needle drop in the Lizheng Hall could be heard.

Empress Changsun and Princess Changle covered their mouths in surprise.

1,200 is the final number after Li Shimin's careful calculation, in fact, Li Shimin still wants more, but for the time being, he is really embarrassed to speak.

Even so, it took Changle a long time to recover from the shock.

"Father, what is the use of you asking for so much?"

"Yes, Erlang, why did you open your mouth and ask for so many sound transmission magic weapons?"

Changle's voice landed, and Empress Eldest Sun also asked in confusion.

"Guanyin, Changle, listen to me carefully......"

Li Shimin talked eloquently and eloquently about his grand plan and blueprint.

Empress Changsun and Princess Changle were deeply attracted by this beautiful idea.

The two of them put their hands on their cheeks and listened carefully to the idea that could be called flawless.

Li Shimin finished everything he wanted to say in one breath.

staring at Changle intently, the only one who can help him realize this plan is Changle alone.

"Father, your idea is really very beautiful, the sons and ministers have just been deeply involved in it, if this can really be the case, it will really promote and benefit the development and construction of Datang."

"1,200 sound transmission instruments, Changle thinks that as long as Changle speaks, it shouldn't be difficult for Gongzi to do it."

Changle's words made Li Shimin's face instantly happy, but immediately after, Li Shimin's expression became slightly heavy.

"Father, this sound transmission magic device needs energy replenishment, and once the energy is exhausted, there will be no sound transmission energy."

"And the magic weapons that replenish energy are all in the hands of Gongzi, Changle thinks that this matter is difficult to do."

"However, the son-in-law will tell the son-in-law about his father's beautiful ideas, and see what the son-in-law has to say......"
