Great Tang princess

Chapter 468 Information Communication Revolution
The dark guard's action speed was also very fast, because the investigation had been clear in the past few days, so after coming over, he broke into the door without the slightest hesitation.

A large number of hidden guards were responsible for the main capture task, and at the same time started operations in many places in the city.

The Qianniu Guard who entered the city was mainly responsible for assisting in the arrest, because heavy weapons such as grenades were in the army, and the dark guard usually had a horizontal knife and a crossbow to arrest people.

This time Qianniuwei came to assist in the arrest to prevent criminals from carrying steel knives and crossbows. Although the possibility is very low, it is still necessary to reduce the danger of their own people.

Qiu Liancai was one of the targets to be arrested.

According to the investigation during this period, this person was a group of bandits who had been entrenched behind the Mang Mountains in the past few years, and they had never done less to rob houses.

Later, when I had money, I bought a house in Dongdu, raised two concubines, and came back for a while during the holidays.

On the sixteenth day of the first lunar month, Qiu Liancai was still sleeping soundly in bed early in the morning.

Last night I went out to watch the lanterns, and it was almost Yin time when I came back. After playing with the two concubines, it was almost sunrise before I fell asleep.

Therefore, he slept very deeply, and only opened his eyes belatedly when the door was broken open and the screams of the two concubines sounded.

Before he realized what happened, he was pinned down on the bed by the members of the hidden guard who rushed in.

"Who are you? I am..." Qiu Liancai, who was suppressed, struggled subconsciously.

With a "slap", a hidden guard suddenly raised his hand and slapped him: "Shut up!"

Qiu Lian, who had just woken up, was a little dazed by the beating, subconsciously closed his mouth, and looked up.

Only then did I realize that the people who came in were actually a group of men in black with short beards!
These people were wearing uniform but strange black clothes, holding bright horizontal knives in their hands, and those behind them were aiming at themselves with bows and crossbows.

Only then did he remember that this seemed to be the military uniform in the Mangshan military camp!

"Are you Qiu Liancai?"

"Exactly..."

"That's right, take it away!"

The hidden guard on the opposite side waved his hand and asked someone to pull him up from the bed and take him away. He just temporarily grabbed a piece of bed sheet and tied it around his waist, and twisted him out without saying a word.

Then the hidden guard pointed to the frightened concubine next to him: "Take these two away too!"

The subordinates agreed, and immediately came and took the two concubines out, but the method was quite polite, they did not beat or scold them, and let them put on their clothes.

Their actions are very fast, and it only takes a few minutes from beginning to end, which is very efficient.

……

The same thing happened in other places in the Eastern Capital. After a while, the bosses of the three bandit gangs were arrested and returned.

They were not escorted to Dali Temple, but to the cell of the dark guard himself.

The cell of the dark guard is specially prepared for the interrogation of some special personnel, so naturally it will not be mixed with the Dali Temple.

Shangguan Wan'er did not participate in the interrogation of the bandits, but handed over all of them to his subordinates, and asked them to report to her after the interrogation.

It's just a few bandits, and they can't speak hard under the interrogation of this special agency. Before they resorted to any means, they basically confessed everything that should be explained.

Two days later, Shangguan Wan'er had obtained a detailed confession.

The matter here has been settled, as long as Qianniuwei has finished the rest of the matter, and after the two sides have checked, they can report to the emperor.

Shangguan Wan'er temporarily put the confession in her office, but then she couldn't hold back the impulse in her heart, and planned to write to Li Yuechen first to report the matter here.

When she was a child, Li Yuechen once asked her about her ideals.

Her answer at the time was to help His Highness do what she wanted to do.

Now this can be regarded as helping her, right?Shangguan Wan'er couldn't help thinking about it in her heart, and smiled happily while writing the report.

……

At the same time, Qingdao is similar.

As soon as the Shangyuan Festival passed ten thousand, Wang Wuqiong and Geng Yunqiang set off with two teams respectively, going to different locations as scheduled in advance, and started the bandit suppression operation.

The hidden guards in Qingzhou, Laizhou and Dengzhou and other cities also started a secret arrest operation, and wiped out all the bandit leaders in the country's Chinese New Year.

After the operation started, Li Yuechen did not follow them to charge, but stayed in the barracks while attending class and waiting for their news.

At the same time, she couldn't help but wonder, should the older Li Shouyi and the others enter the military academy to formally study?
There are still many battles to be fought in the future, and they also need to grow up as soon as possible so that their plans can develop.

It is impossible for Li Yuechen himself to stay in Qingdao for a long time. In the future, someone here will be in charge of the overall situation.

In fact, Li Shouyi and the others should be able to choose one person to stay here in the future and become the leader here.

It's almost time to enter the observation period to see who is the most suitable to stay here.

At the same time, she is still figuring out another problem. If family members want to maintain their relationship, they must communicate frequently, no matter who is left here.

In this era, distance can also smooth out feelings, so communication issues are also very important.

In this era, the fastest speed is only [-] miles, but it is still too slow, so an efficient way of information transmission must be devised.

Recently, I have been thinking about the telegraph, but even if this thing can be realized, I am afraid it will be decades away, and there is no way to spread it all over the country at once, so there must be an existing condition that can be achieved, and it is faster than a horse. Information transfer method.

Now that there are hang gliders, this is a good choice.The idea came up years ago, but never had time to do it.

If a group of hang glider pilots can be trained, the speed of information transmission between Qingdao and Dongdu can be increased by several dimensions.

The future hang glider can reach a maximum speed of 150 kilometers per hour. In this era, be conservative, even if it is [-] kilometers.

From Qingdao to Dongdu, the straight-line distance is about [-] kilometers. That is to say, if God gives me face and the wind direction and other conditions are suitable, I can fly from here to Dongdu in one day with a hang glider. !
Even if there is no way to fly there in one go under normal circumstances, as long as there is a suitable take-off place in the middle, two or three days is almost enough, at least much faster than a horse.

Although the hang glider cannot carry a large amount of cargo, it is no problem to send letters, at least it can ensure flexible communication of messages!
To put it bluntly, it is possible to be shot down even with carrier pigeons, but this thing will not.

Especially if more people know about it in the future, they will understand that this is an object of the imperial court, and it will have a certain deterrent effect on foreigners and some potential dangerous elements.

The most important thing is that hang gliding is much simpler than skydiving and wingsuit flying. Once you are proficient, you don’t even need to take off from the mountain. Find a similar slope and run a few steps against the wind to fly.

Although it is an unpowered aircraft, it is very flexible in operation. In this era, it is definitely the best substitute for horses!
Of course, the post station does not need to be revoked. After all, if you want to deliver goods or something, you still need horses. Maybe it will become an express delivery industry at the right time in the future.

The more I think about it, the more I feel that it is possible, which may lead to a revolution in information transmission in advance!
Thinking of this, Li Yuechen immediately got up and waved to Xiao He: "Xiao He, go grind the ink and get a thicker pen!"

Xiao He was a little puzzled, but she agreed and went to prepare right away.

At the same time, I couldn't help but feel a little puzzled. His Highness usually writes with very thin pens. Could it be that he wanted to try other fonts out of the blue?

After all, what Li Yuechen wrote was a thin gold style that combined hard-tipped calligraphy. He usually wrote with a thin brush, but now he suddenly changed to a thicker one. It's normal for Xiao He to guess this way.

However, to her surprise, when everything was ready, Li Yuechen did not write on the paper, but wrote a big "C".

Xiao He also started to learn to read many years ago, but she didn't know what she wrote at this time.

But if you think about it carefully, it seems like a symbol that Princess Xuancheng and the others occasionally use in arithmetic.

What Li Yuechen wrote was not in English, but a C-shaped vision test form.

For pilots, eyesight is very important, especially these days, there is no fixed flight path and control tower scheduling, everything after flying into the sky depends on the on-the-spot reaction.

Especially when taking off and landing, poor eyesight may cause accidents.

It stands to reason that pilots should not only have good eyesight, but also have the ability to distinguish colors far beyond the average person, but in this era, Li Yuechen can't make a color discrimination card, so he can only work on his eyesight.

Xiao He watched from the side as Li Yuechen kept turning the long piece of paper in his hand, always drawing the same symbol.

The only difference is that the writing on the first one is very large, and then it gets smaller as it goes further back, and the opening is still different. Now that she is standing by the side, she can no longer tell where the opening below is.

……

After a long time, Li Yuechen finally finished drawing the eye chart. After picking it up to look at it, he pasted it on the window and hung it.

The sunlight shining on the paper instantly made the eye chart look much brighter, but at the same time it also became slightly dazzling.

Xiao He was about to tidy up the table, but Li Yuechen waved his hand, and then handed over the ruler: "Xiao He, stand there, and use this to cover one eye by the way!"

Hearing her strange order, Xiao He agreed, stepped back a few steps, and stood less than two feet away according to Li Yuechen's request.

She raised the ruler with some doubts: "Your Highness, which eye should you block?"

"casual."

Li Yuechen waved his hand, then pointed at one of the symbols upside down with a new writing brush: "Compare the opening direction with your hand."

Xiao He blocked her left eye, pointed upwards, then switched to another, and pointed downwards...

……

After 2 minutes of testing, Li Yuechen nodded: "Well, your eyesight is 0.5, which is not bad!"

"0.5?" Xiao He tilted her head, not knowing the significance of this test.
