Datang: Li Shimin begged me to rebel

"Speak well to me." Li Shimin knocked on the table and stared, he didn't believe it anyway.

"Father, what I said is true. Didn't you educate me before that the territory of the Tang Dynasty is so large now that if someone spreads rumors about me in the remote areas of the Tang Dynasty, it is very likely that someone will use my name to rebel , spread rumors, and misinterpret my meaning to achieve their goals?"

"In order to solve this trouble, or to avoid such a situation from expanding, I thought about it for a few days and invented this thing." Li Ke said boldly.

You listen, you listen to what you're saying?Do you think your father and I are an idiot, you think I believe you when you say these words?

The problem is that you are too outrageous. Although I deliberately said this to dig a hole for you, but because of this incident, you developed such a mythical thing. Are you even more outrageous?

Li Shimin didn't know what emotion he should use to face Li Ke's.

"Are you sure you don't have a fever?" Li Shimin looked at Li Ke and asked with disbelief on his face. He was in a state of difficulty, because this thing... was completely different from what he expected.

"Of course, this is easy to test. I have prepared the real thing and can test it at any time." Li Ke said simply.

Li Shimin was in a daze, could he take the test anytime?Doesn't that mean it's true?

"Are you sure?" Li Shimin's eyes were like copper bells.

"Come in." Li Ke didn't bother to continue talking nonsense, but greeted directly, and asked the people waiting outside the hall to quickly carry a small radio directly in.

According to the manual, this small radio has a range of about 10 to 100 kilometers without any problem.

"Chang's servant, please ask someone to prepare a big table and put it in that position." Li Ke found a corner in the Liangyi Hall and said quickly.

Chang Lin glanced at Li Shimin, Li Shimin naturally waved his hand, and Chang Lin immediately went to prepare.

Soon a large table was moved in.

"Go, tell the guards outside the door that everyone outside the hall retreats 20 meters. No one is allowed to approach, and anyone who violates the law will be executed." Li Shimin waited for the table to move in and watched Li Ke's people install it there. He directly issued the latest Order.

Chang Lin immediately went to deliver the order.

After making preparations outside the main hall, the two operators here at Li Ke have already assembled the entire radio station. Speaking of which, there are also many people who have learned electromagnetism and Morse code in Datang. trained.

However, they were all trained by Yuelai Commercial Firm and used to deliver news.

Electromagnetism was added by them later, and after the radio station was taken out, they quickly learned it by operating it, and the next step was nothing more than a problem of unfamiliar operation.

There is no problem in translation. The code they use is also an improved digital code based on Morse code combined with Chinese four-corner numbers.

After the agreed signal, the code book can be used directly. In this case, even if it is intercepted, the content cannot be known without the code book.

Of course, for the time being, this encryption method is not to prevent others from intercepting the telegram, but to keep it secret.

For example, after receiving the information, the person in charge directly translates the information into numbers according to the codebook, and then hands it to the telegraph operator.

The telegraph operator just sends it directly, and during this process, the telegraph operator has no idea what the content of the telegram is, he just knows a series of numbers.

The whole principle is not difficult. Anyway, Pinyin has been invented by Li Ke long ago, and the numbers are transmitted directly in the form of Morse code, and the numbers directly correspond to the codebook, and it is enough to translate it according to the codebook.

This is the simplest and most primitive encryption method, and it is almost impossible to crack it without a codebook.

"How to test?" Li Shimin took a deep breath. He didn't believe it at first, but now that he saw this obviously delicate machine, he believed it a little bit.

If this thing is true... Li Shimin didn't know how to evaluate this matter for a while.

"Hey, father, you can write a piece of paper casually now, and then the regular servant will give it to the Imperial Forest Army outside, and then send it to the post station near the Datang National Martyrs Cemetery about [-] kilometers away at an expedited speed of [-] miles. .”

"Chen has already sent another machine there. According to the speed of the horses, the average speed is about 60 kilometers per hour, and 20 kilometers is 20 minutes."

"After 20 minutes, the news will probably be sent back. At that time, the people here at Erchen will translate it directly. Isn't it enough to compare it?" Li Ke said with a smile.

Li Shimin took a deep breath: "Okay, let's do this. If you are ready, I will start. Chang Lin will let the Yulin army outside prepare horses and prepare."

"Yes!" Chang Lin immediately agreed.

After the people on Li Ke's side debugged it, it didn't take long for the machine to make a "tick-tick" sound. To be honest, Li Ke was somewhat emotional when he heard this sound. Up to this sound is basically in various film and television dramas.

I haven't heard it in reality at all. The radio stations in reality are basically capable of direct conversations. It seems that this ancient telegraph method has long been eliminated.

Now here in Datang, he saw and heard it again.

Soon, one of the two people in charge of operating the radio transmitter stood up directly: "Your Majesty, Your Highness, I have contacted the test station, and the test can start at any time."

"Father, you can give the order directly." Li Ke looked at Li Shimin.

Without further ado, Li Shimin went directly to his desk, picked up a pen and wrote a note, then stamped a seal on it, and then Chang Lin next to him prepared the sealing wax to seal the thing directly.

"Prepare to time." Li Shimin raised his head and looked at the pendulum clock next to him, while Chang Lin quickly walked outside the door.

When the shout of "Eight hundred miles urgent" sounded outside the door, Li Shimin wrote down the time, and then waited.

After about 10 minutes, Li Shimin turned his attention to this side. Li Ke shrugged his shoulders and waited quietly. Suddenly, the machine on their side made a sound again, and the personnel on their side quickly began to receive information.

After they accepted the information, they began to translate quickly. When the translation was completed, the person was taken aback for a moment, but after he was taken aback, he handed the note to Li Ke immediately.

Li Ke reached out to take the note, and when he saw the content on it clearly, his whole face turned dark instantly.

It reads: His Royal Highness Li Ke, King Qin of the Tang Dynasty, wetted the bed for the last time when he was five years old.
