During the famine, my ancient well connected to modern times

Luo Tingye has always had a firm grasp on the method of making glass. Although he later cooperated with the Ministry of Industry, the two largest glass factories are still profitable.

The imperial glass factory was of little use for a while.

"team leader."

At this moment, a soldier wearing a gray military uniform ran in, holding a yellowed piece of paper in his hand.

Lan Yu's eyes lit up, she stared at the paper, and tapped her fingers regularly on her thigh.

"Great!"

Xuan Jiayi glanced at the content on the paper and found that it was some numbers.

The reason why he knew the numbers was because someone used the salt farm. I heard that the empress had developed simple numbers, and even people who couldn't read them could remember them after reading them several times.

Xuan Jiayi knew every number, but he couldn't recognize them when they were connected together.

He humbly asked, "What do these numbers mean?"

Lan Yu did not answer him, but told the soldier, "Reply to Your Majesty and tell him that Qingzhou is ready and can start at any time."

"Yes." The soldier in gray military uniform left again.

Only then did Xuan Jiayi realize that he was different from the other soldiers, especially the clothes and the letter he had brought over. Could it be that he was a messenger?

I never heard that the imperial court specially made clothes for the messengers!

Xuan Jiayi's heart felt as if it had been scratched by a cat, "Lanyu, what does the number you just got mean?"

"His Majesty said the time has come and we can sell the salt."

"Just a few numbers mean this?"

"Don't underestimate these numbers. Numbers are passwords. Different number combinations represent different numbers. Unless there is a code book, no one will know the content."

Xuan Jiayi's eyes lit up, "It's so interesting? Wouldn't it be foolproof if it were used to convey information?"

"That's not necessarily true. If someone cracks it, it will be useless. How about if the method spreads and the enemy uses this method to deal with us?"

Xuan Jiayi immediately covered his mouth, "Don't worry, I won't tell anyone."

Lan Xin was anxiously waiting for the news, but Xuan Jiayi kept asking questions.

"Why are you in a hurry? Qingzhou is so far away from the capital, and it will take several days for the news to come back."

Lan Yu took the time to reply, "That was before."

Xuan Jiayi frowned and asked, "How come it was before, isn't it the same now?"

"Of course not?"

"Why not? Is it possible that you can still send letters thousands of miles away?"

"Of course I can."

"..."

Xuan Jiayi swallowed his saliva blankly, "Do you have the ability to send messages thousands of miles away?"

Lan Yu turned around and slapped herself, but thought that His Majesty did not ask him to deliberately be wary of Xuan Jiayi, and besides, Xuan Jiayi's background had been clearly investigated by them.

Xuan Jiayi seemed to have discovered a new world, grabbing Lan Yu's sleeve and refusing to let go.

"Please speak clearly. I have always felt that something was not right before. I always felt that you could predict the future and let it slip!"

Several times he received eight-hundred-mile urgent requests from the court, but Lan Yu seemed to have predicted it in advance, and he had long suspected that something was fishy.

"Okay, come with me."

Jiang Qian has made radio stations a long time ago, but because they are too rare, he has only made a few of them so far. One is in the palace, one is in Ye Shaohua's hands, one is in Lan Yu's place, and he has no trace of the remaining two.

Lan Yu and Xuan Jiayi went through three rounds of interrogations before arriving at a wooden house covered by a mound of earth. Inside the wooden house, soldiers wearing gray military uniforms were clicking on an iron lump.

As he struck, the iron knot made a ticking sound, a sound that Xuan Jiayi had never heard before.

"This this?"

Lan Yu thought about how she was much calmer than him when she first saw the radio station, and she felt a little proud when she thought about it.

"This thing is called a radio. His Majesty asked Xuanwen Marquis to make it. The radio can spread the message through the clouds. As long as we type the message in digital format, His Majesty can receive the information."

What Lan Yu said was not complicated, but Xuan Jiayi just didn't understand.

“How could the clouds carry a message?”

Lan Yu scratched his head. He didn't quite understand, "Anyway, that's what His Majesty said, and it can indeed deliver the message. Otherwise, you can wait here."

Xuan Jiayi decided to wait, he wanted to see if it was so magical.

The telegraph operator's hands never stopped, and they kept making tapping sounds that seemed to be regular, but in fact were irregular.

Within a moment, the news reached Luo Tingye.

"Qingzhou is ready, where is Lianzhou?"

"As far as your majesty is concerned, Lianzhou is also ready. Hong Yi said it can start at any time."

Hong Yi was the original Hong Er. After Luo Tingye ascended the throne, the three brothers made a request when discussing their merits and rewards, hoping that His Majesty could give them a name.

They had no names since they were young, and after Luo Tingye and Jiang Qian, they did not have official names. Now that they are working in the court, they must have a nicer name.

Luo Tingye named their brothers with the letter of etiquette and righteousness.

Lan Yu watched Xuan Jiayi asking questions, as annoying as a fly, and finally got a little annoyed, "Can you please stop walking around? If something goes wrong, you can't afford the compensation."

Xuan Jiayi immediately did not dare to move.

"Drip drip..."

An electronic sound came.

Lan Yu immediately straightened up and pushed Xuan Jiayi aside. Xuan Jiayi was not angry, rubbed his arms and came closer carefully.

"Ring, ring, ring!"

"Shut up!" Lan Yu took the telegraph operator's earphone and quickly wrote a series of numbers on the paper, in groups of five.

After a while, Lan Yu put down the headphones and wrote the translated words behind each group of numbers.

Xuan Jiayi picked up the earphones, but there was no sound, but he clearly heard the sound of Didi just now. Is this the end?

Lan Yu talked about the yellowed paper excitedly, with a bit of madness in her eyes, "Grandma, we can finally start. I have been waiting for this day for a long time."

Lan Yu summoned all the stewards.

"Each of you go to them with a small jar of salt and tell them that our salt is better than the salt from Jiangnan and is cheaper and can be delivered to your door. In short, as long as they are willing to buy salt from us, there will be a lot of benefits."

"Yes."

As soon as the steward who was sent out left, Xuan Jiayi immediately held Lan Yu's hand and was so excited that he couldn't even speak.

Lan Yu thought he was too excited and ignored him.

Then Lan Yu called people and asked them to put all the salt in sacks and mark them.

Finally, Lan Yu remembered to inform the Ming governor.

"Brother Lan!"
