"Two orioles sing in the green willows, and a row of egrets ascend to the blue sky. The window contains the snow of Qianqiu in the Xiling Mountains, and the ship thousands of miles away from the Eastern Wu Dynasty is parked at the door."

In the other corner, the younger child read out the poem on Pang Yu's calligraphy paper after a while. No one in the room spoke from the beginning to the end. It was indeed a radio transceiver system!

"Great! How powerful is this thing? What's its effective range?"

Facing Pang Yu's ecstatic look, Beiwei couldn't help but laugh - it seemed that everyone who had just seen this machine would ask the same question. And he had already memorized the entire introduction:

"This is a pocket-sized version that you can carry with you. Its basic structure is a copy of the SCR-65-A spark transmitter equipped by the US military in 1918. Of course, the craftsmanship is relatively rough and cannot be mass-produced - including key components such as semiconductors.

We can’t make our own products yet, we all use modern products.”

"Its power is not too high, but in this era, the electromagnetic quietness in the atmosphere is very good without any interference, so the radio wave coverage is much higher than the designed value. According to Teacher Zhang's estimation, there is no problem in covering the Guangdong, Guangxi, and Fujian areas.

Teacher Zhang is also working on a longer-wave radio station with higher power, which will be able to cover the whole country in the future."

"How to solve the power problem?"

Pang Yu raised another key question, and Bei Lai nodded:

"Using a self-made lead plate battery, it is only turned on for one hour a day under normal circumstances, which can guarantee power supply for about thirty days... The power supply is not a problem, and we can let the merchants replace it when delivering goods."

"Have they been trained in cryptography?"

Ade pointed to the two children and asked. When they came out, they only knew that radio had been successfully developed, and they had just come across specific applications.

Beiwei shook his head and said with a smile:

"Not yet. These children just learned to read not long ago. Now they just use Morse code and area code to communicate directly - no one can understand it."

"There is no problem at the moment, but sooner or later... forget it, let's talk about the future later."

Ade did not dwell too much on minor issues. The most critical communication issue was perfectly solved. Confidentiality may as well be considered in the next step. Anyway, in this era, except for them, no one else can receive radio waves for the time being.

.

After that, everyone discussed sending a child to Guangzhou. There was supposed to be a boat leaving the next day, but due to a small accident, it was delayed for another two days - Zhang Anjiang actually came to Qiongzhou in person.

I want to take the child back.

Teacher Zhang has a very high IQ and is very skilled in technology, but his emotional intelligence is low. When Beiwei asked him for help, he casually agreed. However, after several days, he suddenly realized that he wanted to send someone to him.

Where to go? Moreover, Teacher Zhang’s character... according to Beiwei, is a bit like a mother-in-law, with a very soft heart.

Therefore, Zhang Anjiang firmly opposed sending his favorite disciple to Guangzhou to be a spy. He even said that he could go in place of the children. Neither Pang Yu nor Ade could persuade him, and finally Professor Li came forward to have a long talk with him.

, finally persuaded him and agreed to let a child work as an apprentice in Cheng's shop.

"...You are only fourteen years old. For us, you are still at the age where you can act like a spoiled child around your mother. It is already very difficult for them to learn this, and you have to be sent to an enemy-occupied area to work as a spy... Oh, what a sin..."

Although he reluctantly agreed, when the day of departure came, Teacher Zhang still kept mumbling. Even Bei Lai next to him couldn't bear it. He shook his head helplessly and said:

"There's nothing to worry about, Teacher Zhang. I'll take care of you along the way. When you get there, you'll just be doing odd jobs in the shop. It's no different from an ordinary apprentice. You just turn on the machine at a fixed time every day and spend an hour sending and receiving messages."

That's all. As long as he doesn't make a fool of himself and tell it, there's no danger. We also have teenagers like this in our reconnaissance brigade, and their training is much more difficult and dangerous - they also have to learn to do wet work at a young age.

Where is my son!"

Zhang Anjiang sighed and finally stopped talking. But before boarding the boat, he walked up to the child and smoothed out the folds of his new cotton-padded jacket one by one.

"When you get there, be good and listen to your uncle, you know?"

"I know, Master, you have said it many times."

Of course, the fourteen-year-old child could not understand the teacher's mood. Instead, he held his head high and looked very glorious. Teacher Zhang looked at him, then at Bei Wei and others next to him, hesitated for a moment, and then spoke:

"In case...if you are caught by the government, you must be obedient and answer whatever they ask you. Don't lie. Saving your life is the most important thing. We will definitely come to save you, do you understand?"

Next to him, Bei Wei frowned, but didn't say anything. He turned around, looked at Ade and Pang Yu, and said with a smile:

"This is the first time to explore the road. We are going to Guangzhou again. You have acquaintances there... I won't drag you there. But you two had better practice more. There will be many more such reconnaissance operations in the future. I will definitely do it.

I will take turns pulling you out to see the scene for yourself - only in this way can I dare to implement the plan you have made."

The two amateur staff officers could only smile and nod. Bei Lai usually spoke arrogantly and forcefully, but in actual actions he was extremely cautious. This time, except for escorting a small spy, he did not bring any assistants and went alone.

Although some people advised him to bring a local guide to avoid getting a black eye over there, Northern Latitude said it was not necessary. He was familiar with the area from Guangzhou to the Pearl River Estuary. The general topography and landforms should be similar to those four hundred years ago. People

The more you have, the greater the possibility of exposure. If there is any accident, you can run away alone, but you will have more worries if you have a companion.

At about the same time, Lingao County, Hongpai Port.

Ling Ning and Wen Desi were also boarding another boat accompanied by Wang Ruobin. However, this boat was much smaller than an ordinary sea-going ship. The hull was only over nine meters long and the maximum width was only about 1.8 meters. It was just a sampan.

are bigger than it.

But this is an out-and-out seagoing ship, with a slender hull and a deep draft. The cross-section of the hull is different from the usual "U" shape of this era, but a narrower "V" shape. And the most

What is eye-catching is that an extremely long mast extends outward from the bow of the ship, and is connected to the mainmast in the middle of the ship by a triangular white sail. The direction of the sail body and the ship's body are basically the same - this is a longitudinal ship.

Sailboat. Historically, the authentic schooner would not appear until around 1700, but in the hands of this group of people, it was pirated again in advance.

"Is this the legendary flying shear bow hull?"

Ling Ning asked, patting the strange-looking bow. Although it was made of wood, the head clearly showed modern features - a very beautiful streamline shape, and the bow was as sharp as a knife. At a glance, it was clear that it was specially used for

Splitting the waves.

"It's a bit interesting, but not entirely. This is just the first experimental model. It can only be regarded as a racing boat. It is more based on the shape of modern sailing racing boats... Although I have made a model of a clipper boat before.

, but to create a real thing, we can only rely on slow exploration."

Wang Ruobin explained in a seemingly humble manner, but there was still a hint of pride in his tone - he had successfully changed his job from a black gun dealer to a shipyard owner, or to be precise, a sailboat designer.

Being on an island, everyone here knows the importance of developing the shipbuilding industry. But unfortunately, there are no relevant practitioners in their team. Unlike those engaged in construction or mechanical metallurgy, there are knowledgeable leaders who can do it right from the beginning.

Getting Started. Although Huang Xiaodong and others are sailors, they only know how to drive large ships and know nothing about medieval sailing ships.

There are only a few people who, out of personal reasons such as hobbies, have learned some information about ancient Eastern and Western ships. Wang Ruobin is considered a more powerful one among this group of people - he has personally made many ancient ship models, so it is natural.

Become the shipbuilding expert among this group of people. Although compared to the requirements of real shipbuilding, this "expert" is still a bit weak, but it is still better than others who know nothing. It is also due to his efforts that

With the birth of Hongpai Port Shipbuilding Yard.

As a small fishing village port, there was originally no ship repairing place here in Red Card. However, everything changed drastically after the arrival of Shorthair - they initially parked the captured sailboat here for repairs and modifications. After the capture,

After Qiongzhou, the Qionghai shipped back a large amount of wood and a group of shipbuilding craftsmen, and combined with the Western sailors and carpenters captured on the Princess, the shipbuilding yard was officially established.

At this time, the shipyard was in full swing. The keels of three or four ships were spread out on the beach at the same time. A large number of Chinese and foreign shipbuilders were surrounding them, busy like a group of hard-working worker ants.

However, Wang Ruobin, the person in charge of the shipyard, does not seem very satisfied with this.

"Hey, if the situation hadn't been tense, we wouldn't have had to waste materials building this backward type of ship. My next step was to build a few larger schooners, commonly known as 'Schooners', to be used as coastal sentries or

It’s for message transmission, and of course the ultimate goal is the big flying shear!… Now I have to stop for now.”

Wang Ruobin was very ambitious. He originally disdained the manufacture of low-level sand ships and Guangzhou ships. Instead, he planned to do it in one step and jump directly to the 1840s, the peak era of sailing technology, to imitate

The ship type at that time was the so-called "clipper sailboat".

It is said that the clipper boat has reached the pinnacle of sailboat construction technology. It is extremely excellent in maneuverability and can operate freely with only a few sailors. What is most attractive is its terrifying high speed - easily exceeding ten knots.

At the mark, the average speed is 13 to 15 knots per hour. If there is a favorable wind and a strong captain, it may even exceed 18 knots... So what is the concept? The normal speed of the Qionghai is only 10 knots.

Five festivals!

Historically, it was precisely because of this high-speed advantage that even after the advent of steam-powered ships, scissor sailboats continued to compete with them for more than fifty years, and were slowly eliminated until the emergence of gas turbines. {Piao Tian Literature www.
