"Moreover, last year, the Japanese Kingdom exchanged a few gold and silver mines for our support, and it is time to send people to mine!"

Li Eryi patted the imperial case and woke up and said: "How did I forget about the affairs of the Japanese Kingdom!" ”

After that, he hesitated: "How long will it take for your steamship to be built?" ”

"Your Majesty, the steamship is useless for a year and a half. But we have other ships! "Ding Yi came out by himself, Li Er must know what Wang Ziyu did, but he didn't know it.

Li Er said quietly: "Other ships? According to the existing sailing ships of the Tang Dynasty, it is simply not enough to reach the Wa Kingdom across the sea, not to mention that when you come back, you have to carry a ship full of gold and silver. If there is a problem at sea, the loss will be heavy! ”

Ding Yi said naturally: "The minister once cooperated with Wang Ziyu and asked him to find someone to go to sea to find rubber trees. Now a new type of treasure ship has been built, relying on wind and manpower to drive, a treasure ship, at least four or five thousand people! Even if you encounter a storm at sea, as long as it is not too big, there is no problem! ”

After listening, Li Er looked at Ding Yi and said, "I'm curious about what rubber trees you are trying so hard to find, and what they are used for!" ”

After thinking about it, Ding Yi replied: "Your Majesty, have you ever seen the bicycle that the minister just came to Chang'an to ride?" Its tires are made of rubber, and rubber does more than that, a little use can create greater benefits! But it's too early to do that, and you'll find out when you find the rubber tree! ”

Li Er was not dissatisfied with Ding Yi's sale of Guanzi, he understood that even if the other party was over, he didn't understand, so let's wait and see! Ding Yi didn't hide it from himself, and came out very generously, which also reassured him a lot.

"Now that the problem of the ships is solved, let's come and how to safely transport the gold and silver back from the Wa Kingdom!"

If you want to bring back gold and silver from the Wa Kingdom, you must first ensure that you can dig up the gold and silver in the Wa Kingdom, and also ensure that the Wa side will not rebel!

But who can be sure of not rebelling?

The two countries are separated by a vast ocean, and there are very few sailors in Datang, and it will take at least half a year for the news to come over there!

In this way, if the Wa Kingdom really rebels, Datang really has no way!

It's just this kind of thing, how can Ding Yi let it happen?

According to the historical process, the current Gogur Kingdom has entered a stage of decline, and the power of Moli Zhiyuan Gaisuwen has also been confronted with the Goguryeo royal family!

If you think about it according to this line of thought, you will get Li Er back the bones of millions of soldiers, and then you will be scolded back by the people of Goguryeo!

Then the two sides start to do it, add another fire to themselves, and let both sides do it.

Then the people of Silla should come to Datang to seek refuge...... Next, it is to occupy the entire peninsula, and then use the peninsula as a springboard to deter the Japanese state!

But this set of actions is too long just in time!

Not counting the fact that Tuyuhun is eyeing up now, Tubo is also hiding in the dark at this time, ready to take a bite at any time.

There are also the Western Turks, if the Tang Dynasty and Goguryeo are in a stalemate, they will definitely take this opportunity to attack the Tang Dynasty!

Alas!

It is impossible to realize the dream of becoming a general, even if there is a penalty army that Li Er is training, he can't destroy any side!

Everything has to be realistic, sometimes it's not right to think too beautiful!

"The minister may have a way!"

Li Er was surprised: "Come and listen!" ”

"The minister can provide a tool for transmitting sound for thousands of miles, but the price is a bit big!"

"Aren't you that your phone doesn't work?" Li Er was not very surprised, it was not for nothing to keep Ding Yi in the palace for ten years last year!

"Uh~" Ding Yi was a little confused, now Li Er's nerves are big enough! Is the collapsed worldview re-established so quickly, or is it solid?

"It's not a cell phone, it's a radio station!" Ding Yi roughly explained the role of the radio station, and also explained the application of electricity by the way!

After some explanation, Li Er's head was straight when he heard it!

"Just tell me what you want to do! And what price does it have to pay! Li Er also figured it out, listening to Ding Yi talk about things, it's not that you don't need to know the principle, just listen to how to do it, what you need!

Otherwise, he Li Er will have two more heads, I'm afraid it won't work!

And as an emperor, you just need to know about these things, and there is no need to delve into everything.

"Your Majesty, I don't know if there is a world map?"

Li Er nodded, and instead called Chen Hong to find the world map.

Lying on the map, Ding Yi started from the coast of Laiju in Henan Province, connected to the coast of Goguryeo across the strait, crossed Baekje to the coast of Silla near Tsushima Island, and finally connected to the northern coast of the Wa Kingdom.

"Your Majesty, please see, the minister can provide several radio stations to connect this line, and the message transmission can be completed in the time of a stick of incense!" Ding Yi has already seen the price of the radio station in the system mall, and without satellites, the transmission distance can reach 300km, a 200,000!

With Ding Yi's current value, he can exchange for four, and after the exchange, he can withdraw the civilization points accumulated in the past half a year again and exchange them for three to five again!

Li Er has now accepted this kind of cognitive impact from time to time, holding back the shock in his heart, and asked with some disbelief: "How far is the transmission distance?" ”

Ding Yi had already told him about the role of the radio station earlier, and Li Er slowly understood.

"Extreme...... It should be five hundred and fifty miles. But it depends! Ding Yi calculated in his heart that one mile of Datang is about 540 meters in the future, so it is less than six hundred miles.

Tong!

Li Er sat directly on the map in shock, it is one thing to accept it, and it is another thing to hear the specific data!

Such a fast way of communication, if Datang can have it, is it afraid that it will not be able to manage the frontier?

When the army goes out, he can sit in Chang'an and command!

Looking at Li Er's imaginary look, Ding Yi reminded: "Your Majesty, this kind of thing can't be provided by ministers, it's not enough to cover the entire Tang Dynasty!" ”

Li Er came back to his senses, wiped the non-existent Harazi, and said with an embarrassed smile: "Hahahaha~ Such a divine weapon, it is already a great luck to be able to get a few, how can I not be satisfied!" ”

What about liars! Your expression has betrayed you!

"Your Majesty can understand best, the minister is dedicated to the state affairs of the Tang Dynasty, and the things that can be taken out will never be hidden. This time he took out the radio station, and the minister had already done his best, if he still ...... in the future" Ding Yi shook his head and sighed, the loss was heavy! If you hand over the radio station this time, you will definitely never get it back, and you have to think of a way to reduce the loss!

Li Er immediately understood that Ding Yi's ability was not omnipotent, as for whether this son was hiding his secrets......

Hum!

It's no wonder that there isn't!
