Chapter 913 The Yellow Sparrow is behind

Originally, he was going to hide it from Zhang Fan's book demon, but after looking at the ship at close range, he immediately knew that the ship must have used a propeller propeller that was more advanced than the bright wheel paddle. But the problem is that the propeller propeller was not invented by British scientist Hooker until 120 years later. How did it appear in this era?

After learning about Baca's background, the puzzle was solved. It turned out that this guy was a descendant of the ancient Phoenicians and claimed to be the descendant of the famous Carthaginian general Hannibal. So his pirate group is called 'The Sunset of Carthage'. The propeller was inspired by the spiral water pump invented by Archimed in Egypt.

At the beginning, the propeller propeller is an enlarged version of the spiral rod. This spiral rod pump is still widely used in Egypt and is called a spiral transporter in modern industrial applications. Carthage and ancient Egypt belong to North Africa, and this kind of spiral pump has often been seen since childhood. Baca also accidentally found that the half-damaged spiral rod pump could make a small wooden boat move forward in the water. Therefore, he studied along this road, and after more than ten years of experiments, she finally developed the propeller propeller, that is, the early propeller propeller.

Therefore, there is this 'Sunset' propeller ironclad ship! However, there is no steam engine in this era. This kind of original propeller propeller can only be rotated by manpower. Even so, this power is better than the open paddle after solving a series of problems such as hull sealing under the waterline, hull vibration during rotation, bearing wear and so on!

This ironclad ship book demon is determined to be obtained, because propellers can be made, and ships using propellers can also be made, but if the 'Shengyi' wants to advance, it must integrate the spiral propeller props on this iron-clad ship. However, the captain Baca is still mysteriously unwilling to disclose his invention patent.

The book demon shook his head with a smile, drew a spiral rod on the ground with a branch, and said to Baca, "I know everything, and even more. We can also help you improve this ship. Your armored ship must be leaking frequently. Moreover, the connection between the propeller and the hull is easy to wear and difficult to repair. All this, we can help you improve..."

"But we need your ship, let's make a price..." The book demon threw away the branches and looked at Captain Baca calmly. His words made Baca panic, and the muscles on his face beat, betraying his inner fear.

"How did you know?" Baca looked at the book demon, "In this world, no one can know this discovery. If anyone had found this secret, the world would have been full of ships.

The book demon said lightly: "Although this propulsion is advanced, it requires a lot of manpower, which is similar to a paddle boat and is not suitable for ocean voyage. Only sail-powered ships can get continuous propulsion in long-range navigation. And this propulsion has been used in the far east, but the form is not the same.

Baka originally wanted to kill people in order to keep this secret, but he was discouraged by the book demon's words. Indeed, it takes a lot of force to turn the machinery to make the screw rotate and make the ship move forward. What's the difference from a paddle boat? It is never suitable for long voyages. If Columbus used this boat, it would be impossible to cross the Atlantic to discover the New World.

How did he know that the propeller thrusters work completely in water, which is much better than most of the power effects of paddle boats and open-wheeled paddle boats on the water. Moreover, it also reduces most of the inefficient weight compared with the bulky open paddle. Even if the manpower is also used, it is more economical than the paddle and the open paddle, and it is efficient and high-speed. It's just that his screw is only the primary stage of the propeller, and the efficiency is still very low. If you can use a modern form of propeller and cooperate with the sail, you can naturally make the propeller ship sail!

Captain Baca sighed, "Well, now that you have cracked this technology, this ship will be given to you for the sake of saving my life and returning to my hiding place. I just hope you keep this secret in the Caribbean and the Mediterranean. If the Spaniards knew about this propulsion technology, it would be more difficult for us to deal with them.

The book demon nodded, "Of course, we are also enemies of the Spanish fleet, and we will never let them acquire such technology. I hope that we can cooperate well in the future and make the Spaniards pay a heavy price.

Captain Baca looked at the dozens of people he had left and shook his head with a wry smile, "I'm finished. Do you know how many years it took me to accumulate so many warships? Eight years! In less than a day, the clouds disappeared! Most of the ironclad ship in my hiding place has only been completed. Even with this ironclad ship, I can't restore my original strength.

The book demon thought for a moment and said to Captain Baca, "You are an excellent shipmaker and mechanical expert. Unexpectedly, you came to the Caribbean to be a pirate. And it has done so well. We have a friend and a very good mechanic who may share a common language with you. There are still many improvements to your ironclad ship, and he will be able to give good advice. If there is a chance, I will introduce him to you, and maybe you won't be so depressed. The book demon instinctively felt that the pirate leader had a relationship with Aken.

Baka smiled and said, "Maybe, my biggest dream is to build the world's best ocean-going warship. In the name of my ancestor Hannibal, I defeated the Holy Roman Empire and the Spanish fleet, just like the invincible Red Beard in the Mediterranean 30 years ago. Being a pirate can make me earn money to develop this armored warship, and also teach the Spanish fleet like my ancestor Carthaginian Hannibal, so I did it.

Zhang Fan listened to Captain Baca's words and sighed in his heart that each of these best pirates in the Caribbean had their own ideals. But they basically have the same goal, which is to attack the Spanish fleet. It seems that Spain has seized the interests and dreams of many people in the process of expanding its colonies in the new continent!

After three days of rest in this bay, Captain Baca's armored ship has regained some durability. So he took Zhang Fan's book demon and circled the island of Haiti. It took him a week to drive to his hiding place on the north coast of Haiti Island. It is a very hidden bay, located ten kilometers west of modern Cape Haiti, less than 30 kilometers from the notorious pirate island of Tortuga. It is a quiet sea that ships rarely pass through. With beautiful scenery and hidden bay, it is a good hiding place.

This bay is gourd-shaped, two kilometers wide and six kilometers deep, with a small mouth, and two headlands guarding a 600-meter-wide waterway. Six kilometers away from this bay, there is an indigenous village called Lambe, which provides daily supplies for Baca's hiding place. This paradise-like hiding place makes book demons and Xuanyuan Xing very envious.

"The coward Victor seems to have a map of the abandoned harbor hiding place in his hand. Although it is not as good as my hiding place, I heard that the location is good. Next time I have a chance to meet this guy, I will help you come here. If he is still alive." Baca was a little proud and said carelessly, "However, in this naval battle, Victor seemed to be very brave, and even the flagship rushed up and was blown up!" I don't know if he succeeded in breaking through. But that boy is so slippery that he probably won't die..."

Zhang Fan was not interested in these. He saw that he had had a good relationship with Captain Baca, the second-ranked one of the five largest pirate groups in the Caribbean, and had got a broken new propeller ironclad ship, which had exceeded the task assigned by Akan, so he wanted to leave. He is very worried about the safety of Green Wing Aken.

This armored ship can't leave for the time being and can only be temporarily stored with Captain Baka. Zhang Fan and the three of them said goodbye to Captain Baca, took the Necromancer and went to Port-au-Prince. There is a detailed map in the book demon information, and Port-au-Prince is directly south of Captain Baca's hiding place. The bone dragon flew south for a long time and landed in the wild in Port-au-Prince.

Zhang Fan rushed into the port, but did not contact Aken and the others, and he was a little anxious. Finding the pub, he found the code left by Katrina and Akan, found a pirate eyeliner of Catherine's confidant waiting here, received a fire seal from him, wrote a secret letter in Chinese, and learned that Akan and Katrina had successfully robbed the Spanish transport fleet and hijacked it. Two Spanish treasure ships carrying gold can be said to have returned with a full load!

It's just that six Karak galleys cannot enter Port-au-Prince and must be modified in a pirate hiding port before they can be sold. Otherwise, we will have to go to the UK to deal with these stolen goods. But such a harvest is not safe even if the pirates hide in the port, because it will inevitably make those pirates jealous and attract a lot of wind, causing unnecessary trouble. Although the Caribbean Plunder Convention is effective, if even the makers are jealous, there are no rules to talk about.

But in order to avenge, Captain Hooker intercepted Victor, who was running wildly, and got half of the chart of the abandoned harbor hiding place from him...

............

After Aken explained Zhang Fan, he urged the Goblin, who controlled Muyuan, to immediately fly to the Spanish transport fleet. Let the female pirate intercept the four Spanish transport ships that had left the battlefield in the air. He landed on the sea, summoned the 'Saint-Sacred', and followed the Spanish transport fleet to catch up...

The result was not unexpected. Two Catalina's warships were intercepted in front of them, and the 'Saint's' blocked the way behind them. There were also two anti-water convoys that disrupted the situation. Four Spanish transport ships, which had long lost their combat effectiveness, could not be beaten and could not run away, so they had to be captured obediently!
