"Slow down! Slow down! ”

On the route from Luzon to Fujian, the sailors and pot-bellied merchants on the slow Fu ship were either stunned or frightened to see a number of strange-looking but amazing-speed ships flying past them, and the waves raised by the ships were tumbling and almost splashing onto the deck of the Fu ship.

These lucky ships took the concession and the customs documents to go to Luzon to sell rice, jaggery, tobacco and other goods back to Fujian, and when they came, they saw these ships galloping back and forth on the sea, and in Luzon they also saw these ships replenishing supplies and resting on the docks, and they did not want to go out for two whole days early, but they were still caught up.

In the envious and horrified eyes of the merchants, they did not know how much of a crime these sailors on the flying clippers had suffered behind this seemingly beautiful scenery.

A few hairy boys who have just graduated from the Sailor Academy are obviously rookies, and at first they experience such a high-speed voyage, they can't help but feel a little pale, coupled with the bumps brought by the high speed, the morning meal, gastric juice and even bile have become food for the fish, shrimp and seabirds in the sea.

The main mast on the flagship headed by the leader fluttered majestically with the handsome flag of Zheng Zhilong, the commander of the naval division of the Nanyue Army.

The flagship pipe officer, Zheng Zhilong's old subordinate Chen Peng, was also pale, but his physiological instinctive reaction did not hide the excitement in his heart.

"Lord Admiral! This ship is amazing! ”

Zheng Zhilong, who was standing in the rudder tower of the ship, narrowed his eyes that were a little red from the sea breeze, and through the lens of the telescope, he used the speed of the Fu ship next to him as a reference, speculating and estimating the speed of his fleet in front of him.

"The chain rope can be collected!"

I looked at it for a while. He probably had a base for his sailing speed, and whispered to Chen Peng to give the order to put away the chain rope used to measure speed, and he wanted to have a full understanding of the speed.

After a long while, Chen Peng came in from outside the cabin in a huff.

"These guys, clumsy! Even a chain rope is so slow! If it's all our old brothers, we still need to do this......"

"Shut up! Let's talk about the chain! ”

After the Battle of Xiamen, Zheng Zhilong's subordinates and those maritime subordinates who surrendered to Cheng were incorporated by the naval division of the Southern Guangdong Army and sent to the camp of the Naval Academy for three months. The main thing is to teach sailors to read. Then there is the training of various military systems and military discipline in Nanyue. After completing this process, these sailors were numbered from one to ten by the Sailor Academy according to their professional, technical level, etc., and then divided into ten large pieces.

After the original establishment and interpersonal relationships were completely disrupted. The sailors were assigned to various ships. Sailors don't matter. Everywhere they are paid as soldiers. Moreover, not to mention the military salary here in the Nanyue Army, you can climb up if you do a good job. However, the officers under Zhilong were a little unhappy. Although the original position and military salary have not changed, the people under him are not the same as before.

It is Zheng Zhilong himself. I was also helpless to find that even my own flagship, the original ship of the Shouhan Fubo, was more familiar with a captain Chen Peng and dozens of his own personal soldiers.

Complaints and dissatisfaction can only be in the heart, and they dare not show the slightest outpouring. However, over time, people became familiar with each other and blended together. It is no longer distinguishable from the original Zheng Zhilong's gang or the old Nanyue army sailors, Fujianese, Cantonese, Arakan, Japanese, and Siamese people, all on the same boat, operating according to the boss's command, this name is the old name, but the ship is a new ship that has recently been launched.

This ship can be regarded as a comprehensive embodiment of the current technical strength, economic strength, and scientific and technological level of the Nanyue Army.

The length-to-width ratio of more than 6:1, the long, sharpened curved scissor-shaped headpost, the three masts, which reached the height of three-quarters of the length of the hull, were divided into five layers and hung with huge sails, and on the top mast there were also moon sails and strands, and on both sides of the ship there were outstretched sail trusses, called wing sails, which could have been hung to increase speed, but because the sailors could not adapt to the great physical and psychological impact of this high speed, they had to let the sea breeze pass by at high speed.

The curved scissor-shaped head column is very good at running at high speed, constantly splitting the waves on the sea surface to reduce the resistance brought by these waves, and because the curved head column extends the hull, there are also several triangular sails hanging on the slash of the bow sticking outward. The increase in the number of sails greatly improves the power of the boat, and the underwater shape of the body, which is designed to have the lowest drag surface, plays a key role in reducing drag and increasing speed. The hollow bow makes it easy for the boat to lift its head in the waves, and improves its course stability in the waves. The sloping waterline that gradually changes at the rear transitions harmoniously to a narrow round tail, harmoniously blending in with the graceful bow shape.

Glancing at the five almost identical ships on the sea with a somewhat intoxicated look, Zheng Zhilong sighed secretly in his heart, even if he won the battle of Xiamen that day, he was afraid that he would be killed by the huge advantage of the Nanyue army.

His son Zheng Sen studied in the Sailor School, and almost every day he wrote to his father, telling what he had seen and heard, and the more he had a deeper understanding of the group of the Nanyue Army, the more terrifying he felt.

As far as the Fubo in his hand is concerned, there are special people who design the shape, calculate the speed, how to increase the sail for the speed, reduce the drag, in order to achieve the optimal design effect, that is, the aging dragon clock Galileo, addicted to mathematics Descartes and others are also on the battlefield.

Unlike the design of official ships in the mainland, a few craftsmen revise and modify the bells and whistles drawn by the officials, and then manufacture the ship board and make the keel according to the experience in their heads, and after spending a few months on the slipway, they carry out tedious and complex decoration, turning the ship that should have pursued speed, capacity and firepower into a quasi-dock that moves slowly and slowly, and the decoration is very gorgeous, but no matter how gorgeous the dock is, isn't it also an obvious target when it comes to the sea?

For those blonde and blue-eyed red-haired people, Zheng Zhilong also thought it was nothing more than that at first. You can only do some calculations other than casting guns, but. When he saw the five ships lined up in the dock in the shipyard, he was shocked. When he realized that a large part of the credit for this was to Monsieur Descartes, he became more and more unclear.

In fact, it is worthless to say it.

This is just Descartes' application of his theoretical research results in coordinate systems to actual production. Everyone has found their own seats in theaters, stadiums and other places, and they only need to find their seats according to the seat number marked on the ticket, which is actually the simplest practical application of coordinate system theory in daily life.

Descartes turned the finished sketch of the clipper into a huge coordinate, and compiled every keel, every plank, and every deck in this coordinate system, and calculated the dimensions at the same time.

Each board and deck is represented by the three numbers A, B, and C, and the position marked by the three numbers jù is the position where the plate is located on the ship. (Isn't it a bit like being in a certain stand, a certain row of seats?) These numbers marked with size, thickness, and wood quality requirements are put out for public bidding. Purchase suitable timber from timber merchants from all over the south. All you need to do is process the timber we need to the dimensions provided to you and transport it to the place of delivery designated by me, and you will be able to get the price according to the contract.

So. The process of drying, decomposing, and processing wood into suitable dimensions for a long time no longer appeared in the process of building ships in the Southern Yue Army. The craftsmen simply had to combine the huge thick plates with the keels made of wrought iron, as indicated on the drawings.

In this way, some low-tech links and processes can be outsourced to the greatest extent possible, and there is no need to worry about leakage. Any one of the contracts was reviewed jointly by several major intelligence services and shipyards. No matter how the collage is, it will not reveal the design scheme of the boat. Confidentiality is kept to the greatest extent possible.

Meantime. According to the construction of this group of mathematicians, in addition to the design of the hull to reduce the resistance of the seawater, the hull structure of the five clippers has also undergone heavy changes. Taking full advantage of the stability of the triangle, three were taken

The angular structure stress bracing method not only saves the space inside the cabin, but also greatly reduces the cost.

"This group of red-haired people is really a bit evil!" Although Zheng Zhilong didn't understand why Li Shouhan had to let these people intervene in anything, he had to say very convincingly that with these people, many things seemed to be very simple.

"My lord! The speed stats are out! Chen Peng was very excited. There were even some beads of sweat coming out of his face.

"How much?"

"Twelve nautical miles!"

As soon as this remark came out, the sailors were in an uproar.

It is also full of goods, compared with this flying clipping ship, the speed of the lucky ship is at most seven nautical miles, and Zheng Zhilong's five ships, in addition to the task of adaptive training, also loaded tens of thousands of stones of raw sugar, tobacco and other materials in the cargo hold of the ship, ready to be transported to Fujian and other places to be handed over to the merchants of Longsheng, which is also a business entrusted by the firm to traffic.

These coarsely processed cane sugars, as well as the fine tobacco produced in Luzon, were subject to high taxes according to the tax regulations of the Southern Yue Army. Tobacco is subject to 17 percent value-added tax when it is purchased in the field, and 40 percent consumption tax is charged when it is sold on the field, but it is still in short supply when it is transported to Jiangnan, Central Plains and other places. With such huge benefits, Zheng Zhilong naturally had to be more careful.

This is one of the reasons why Zheng Zhilong did not dare to raise all the sails, and the other reason is that this group of sailors is really too vegetable. However, ask yourself, Zheng Zhilong has never encountered a ship that can still speed on the water when it is fully loaded.

"If such a ship raises its sails and only transports people and not so many goods, it will be a trip from the Hue palace to the capital, and I am afraid that it will be able to go back and forth within a few days."

Zheng Zhilong began to carefully calculate in his heart.

Thanks to the courses offered by the Sailors' Academy, sailors can now sail without following references, that is, they can avoid the islands and recover to the point where the stars are and so on, and use a sextant to calculate their technical level.

If it is used to transport goods, and then the sailors in front of them are thoroughly trained, so that they will not be frightened and cry when they are speeding on the sea, but they are afraid that the speed of this ship can be faster. At least it can be more than double that of Fufu.

Zheng Zhilong didn't know that because of the industrial standards of the Nanyue Army in the Nanzhong region for many years, such a ship could completely form an assembly line production, as long as his sailors could be trained quickly, there would be more or less such ships.

The use of clippers as the main ships for rapid deployment and rapid transportation, and the use of fortune ships as fleets for large-scale transportation to the interior, such echelon deployment is the consensus of the Southern Guangdong Army on the building of maritime forces. In this way, the respective advantages of several ships can be maximized.

Zheng Zhilong, who delivered the goods transported at Xiamen Port, was about to set sail and anchor. Go to Hue. But Zheng Zhibao's boat appeared on the sea.

Zheng Zhibao, as the secretary of the Reclamation Bureau, is specially responsible for the development and utilization of tidal flats, swamps, mountains, forests, saline-alkali lands in Fujian, Guangdong, Guangxi, and Taiwan's coastal areas, and the resettlement of people in various places.

There are also old people in the Southern Guangdong Army who call such a year-end activity a year-end summary and commendation meeting.

Not seen for months. Both brothers felt the change in each other.

But I didn't know how to talk about it for a while. And so. "Zhibao, you can get on my boat, my boat is fast. You and my brother will go together. Just on the way to talk something. ”

"Brother Yi."

In the cabin, the two brothers didn't know where to start. This kind of taste of being the master of their own house to working for others may only be able to taste it slowly by themselves.

"Zhibao, when you came to Hue this time, did you have anything that you could mention on the tail teeth?" After a while, Zheng Zhilong spoke, he was concerned about his brother's work performance these days. Since he is already under the banner of Li Shouhan, if he wants to establish himself in the large group of the Nanyue Army and let others look up to the Zheng family brothers, he must show some real skills to speak.

Zheng Zhibao didn't say much, and motioned to his subordinates to take a rattan box. In the rattan box are neatly placed four small tin jars.

"Big brother, this is my achievement this year."

Since the beginning of the spring and March, several brothers were captured, and the Zheng group, which had been dominating the East China Sea and dominated the East Asian seas for many years, was completely annexed by the Nanyue army.

"This is a few tea trees transplanted in the mountains and forests of Taiwan, and the tea leaves picked in autumn cannot be said to be the taste and quality, but they have also spent a summer and an autumn in Taiwan, indicating that the tea trees can survive in Taiwan."

"This is what I planted near the saline-alkali land of the beach flats in Guangxi, tung oil seeds."

Proudly pointing to the four inconspicuous tin cans, Zheng Zhibao talked eloquently.

Tung oil, an excellent vegetable oil with dryness, has many physical advantages such as fast drying, light specific gravity, good gloss, strong adhesion, heat resistance, acid resistance, alkali resistance, anti-corrosion, anti-rust, and non-conductivity.

For the industry of the Southern Yue Army, it is an indispensable raw material and component. Construction, machinery, shipbuilding, weapons, vehicles and ships need it for waterproofing, anti-corrosion, anti-rust, soldiers' ponchos, artillery jackets, a large number of books and textbooks printed and distributed free of charge to school children in various places, a large number of soaps and soaps exported to Jiangnan to earn a large amount of gold and silver, and even all kinds of experimental drugs used to control pests in the farmland, drugs for treating burns and scalds.

For this, the Nanyue army had to trade a large amount of materials, weapons, armor, cloth and other materials with various forces everywhere in exchange for tung oil.

As the Ma family of the Emperor of Shizhutu, Qin Liangyu exchanged tung oil for her weapons, armor, farm tools and cloth to expand the army, restore vitality, and recuperate, and pulled up a team no less than the scale of the white pole soldiers in their heyday.

Zhang Xianzhong and Luo Rucai, who are wandering around Sichuan, also regard this kind of liquid, which cannot be eaten by people and can only be used for painting, as a hard currency comparable to gold and silver.

Going down the river, the five battalions of the Huige that have been entrenched in the Dabie Mountains for many years have regarded the tung oil forests in the Dabie Mountains as an important source of military salaries and ordnance, and thousands of stones of tung oil are transported across the Yangtze River every year to Nanjing for delivery, in exchange for all kinds of materials they need.

The warm and humid climate of Guangxi is no less than a paradise for tung oil production and tung tree planting. The crop is grown in almost every county in Guangxi, but Zheng Zhibao is determined to take its cultivation to a larger scale.

After accepting this mission from the Reclamation Bureau, Zheng Zhibao sent people to buy a large amount of tung oil seeds with tens of thousands of silver dollars, and ordered people to bring a large amount of silver dollars, cloth, and grain to Li Huabao, who was carrying out road construction activities in Guangxi, and asked the second son to send people to take them to meet the Tusi and Tu prefects of Guishun everywhere, and regard tung oil planting activities as an economic activity for these Guishun Tusi.

"This is three years of paulownia, this is five years of paulownia. It is a variety that I have promoted and planted in large quantities in various places in Guangxi. ”

Pinching a few tung seeds taken out of the tin can, Zheng Zhibao showed a cruel smile on his face.

Zheng Zhilong is very aware of the infinite killing motive hidden in this practice of the Nanyue Army, and like tea, once the hungry and cold crop of tung oil is promoted in the areas to which the toast belongs, it is bound to greatly reduce the grain planting area.

At that time, these toasts just wanted to rebel and rebel, and they only needed to cut off their food and other daily necessities, and this group of people was a group of turtles in an urn. (To be continued......)
