As she spoke, she took the model of the boat and pressed a small switch, and the propeller suddenly turned, and the drive device was nothing more than a No. 5 battery and a small electric rotor removed from the toy. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Big girl, Chen Qingdai and Wu Qing came to a small pond in the village, put the boat model down, driven by the propeller, the boat model drove fast, Wu Qing applauded: "It turns out that Mr. Houlong has already made a strong boat cannon, but it's ridiculous that I'm still playing with my tongue." ”

Da Niu said: "Brother Guo just made a model, and did not start to build the real thing, but I didn't expect the Fanren pirates to invade so quickly, and what's worse is that they still have black powder in their hands, so it seems that we have to hurry up and build the propeller ship designed by Brother Guo, and eliminate the Fanren pirates entrenched on Yizhou Island in one fell swoop." ”

Chen Qingdai looked at Wu Qing: "Mr. Wu has a block, it is really condescending to be a small businessman, can Mr. stay in Houlong Village and destroy those pirates with me?"

Before Wu Qing could speak, the big girl was anxious, and complained to Chen Qingdai: "Sister Daiyu, Mr. Wu Qing has his own family, how can you force someone to stay in Houlong Village, and after Mr. Wu Qing recovers from his injury, he will return to his hometown." ”

Wu Qing said: "Thank you Mrs. Guo for your care, Wu is an orphan, I don't know my parents, I don't have a family, I wander all over the world alone, do some small businesses that barely make ends meet, and what I love most in my life is to study the science that Mr. Hou Long has passed down." If you are lucky enough to stay in Houlong Village, it is really your life's wish. ”

Chen Qingdai laughed and patted Wu Qing's shoulder heavily: "What's the meaning of being a businessman who flies and dogs, I think you are a very smart person, and you will definitely be able to make a career in our science gate." ”

Chen Qingdai sincerely appreciates Wu Qing, there are many students in the science of righteousness, but in Guo Dalu's words, there are not many people with subjective initiative, most of them are dead memorization, dead books - in fact, students do not study well, the biggest reason for this is still Guo Dalu himself, he is not a good teacher at all, and the things he teaches are not systematic。

This is the reason why the scientific knowledge of the 21st century brought by Guo Dalu is too disconnected from the original knowledge system of the Great Li Dynasty.

You must know that the science of the 21st century originated from the ideological enlightenment movement, has a strong humanistic foundation, the progress of thought, the emancipation of human nature, and the beginning of basic science, all of which did not come out of thin air, and the people of the Great Li Dynasty pouted their butts and shouted Long live the emperor, only knowing that they would pray to God and worship Buddha.

It's no wonder that when Chen Qingdai saw a self-taught person like Wu Qing, she suddenly fell in love with talent, and even said to keep her - she wasn't worried about what kind of spy Wu Qing would be, Wu Qing saved the big girl, that was sincere, almost lost her life because of the big blood loss, who would do this in this world?

Chen Qingdai is a fiery personality who does what he says, and immediately pulled Wu Qing and discussed with him about the transformation of the sailor's warship, and the big girl was so anxious next to her that she stomped her feet: "Sister Daiyu, Mr. Wu's injury is not completely healed! ”

Wu Qing said: "I'm fine, Mrs. Guo's operation is extremely exquisite, and I can already move on the ground." Although he is now in the territory of the Great Li Dynasty, Changshengtian's spiritual power is much weaker, but it is a trivial matter to help him accelerate wound healing and physical recovery.

Chen Qingdai patted Wu Qing's shoulder again: "Great, I just like your straightforward temperament, let's not fight now, just discuss the transformation of the ship, do some homework on the map, and I can't kill people from exhaustion." ”

Chen Qingdai and Wu Qing lay on the table, writing and drawing, and arguing fiercely, and finally decided that there was no such ability to build an all-metal ship for the time being, and there was no need for that - the black powder of the Fanren pirates was not very powerful, and even a harder ship board could not be blown through, so the solution to the word "strong ship" was to lay copper skin on the ship's board. It is not even necessary to cover the whole ship with copper skin, as long as it is covered above the waterline, it is enough to protect it.

Compared with protection ability, Chen Qingdai and Wu Qing both attach more importance to mobility ability. Wu Qing said: "The Fanren pirate ship only needs to rely on the wind, and our ship relies on propellers, not only can it sail without wind, but it can advance and retreat as freely as against the wind. ”

The propeller manufacturing is not complicated, far from using any multi-axis machine tool surface processing, Li Dayan directly cast several propellers with molten steel, as for the original most difficult power problem - there is a big black machine forever, it is not a problem at all.

However, the sealing of the propeller bearing is a problem, Chen Qingdai and Wu Qing tried the raw rubber, but the sealing performance is not as good as imagined, the final solution is to install the bearing on the waterline, and insert the propeller obliquely under the water surface, so that although a little power is sacrificed, there is no need to worry about water leakage.

Chen Qingdai is a do-it-all character, and Wu Qing ate a few bites of supper served by the big girl, pulled him to the Sanjiangkou wharf, and directly pulled Shi Xiaofeng's best boat to the slipway, and commanded the craftsmen of Houlong Village to start refitting.

Chen Qingdai is the body of the dragon girl, Wu Qing is blessed by the immortal heaven, the craftsmen are tired and yawn, but the two quarrel for some details, and in the end, the big girl forcibly pulled Wu Qing back to Guo's house to sleep in the name of Wu Qing's injury, and then stopped.

Two days later, a golden ship appeared on the dock of Sanjiangkou, half covered with copper skin, shining in the sun, as if it were made of gold, except that the ship had no mast sails, only a small blade at the stern.

Wu Qing stood on the shore and shook his head vigorously: "Waste, it's really a big waste, it's too expensive to use copper, in fact, it can be completely made of stainless steel from the Houlong Village workshop, and the shape of this ship is not good, there is no watertight cabin, the bottom of the ship is too flat, the draft is too deep, and the deck superstructure is too complicated--" But although he complained so much, the corners of his mouth hooked up a smile, because this ship was built by his own hands, the first propeller ship in history, and its birth will make the four seas tremble.

Moo, with a call, Da Hei was reluctantly pulled into the dark cabin, it is also really hard, Guo Dalu has not invented a qualified power system so far, all the workshops, railways, all need Da Hei to work hard, and he has really become a tired old scalper. Now, even in naval battles, it is required to contribute.

Fortunately, the LED lights were lit in the cabin, and Chen Qingdai hugged some of the metal objects transmitted from the trash can, bribing Da Hei, who put on the gear system and slowly circled around.

Shi Xiaofeng had already boarded the warship, and was wondering how to sail without sails and oars, when suddenly his body shook, the ship had no wind and automatically got up, Shi Xiaofeng was dumbfounded, and then shouted wildly: "His grandmother's, Lao Tzu has such a boat in hand, and it is no problem to cross the sea!"

Chen Qingdai and Wu Qing drove the boat to run in Sanjiangkou for a few hours, and found that the bearing was easy to overheat under high-speed rotation, deformed and stuck when it was hot, but Li Dayan's alloy steel was still not up to standard, so they installed a seawater cooling system - in fact, it was arranged for several crew members to use a hand pump to pump water to cool the bearings - such a shoddy thing, of course, is not a long-term solution, but Chen Qingdai was anxious to wait, just wanted to kill Yizhou Dry Port in one go, single-handedly, and overturned all the pirates in the sea.

That night, the wind and waves were calm, it was a moonless night, the big girl stood on the Sanjiangkou wharf, waved at the "Zhenyuan" - Wuqing gave the remodeled warship such a name - waved her hand, and the tail of the Zhenyuan waves surged, and sailed away from the port silently.

Sailing at night was originally extremely dangerous, and many old crew members only dared to drive on the shore on a moonlit night, lest they lose their way, but on the Zhenyuan ship, Chen Qingdai held a sextant, wrote and painted against the starry sky, and reported one number after another, guiding the ship forward - Guo Dalu copied the navigation chart of the 21st century, anyway, the islands on the sea will not run away with long legs on their own. It's just that he changed the starting point of Greenwich and set his own Guo house in Houlong Village as the prime meridian, otherwise he would not be able to explain to his students what the hell the Greenwich Observatory is.

In fact, Chen Qingdai doesn't need to be so complicated at all, as a dragon, she knows the situation at sea well, and the reason why she uses the sextant is to guide the righteous young soldiers who accompany the ship, as well as Wu Qing.

Wu Qing was indeed very talented, and soon learned to use a sextant to determine the bearing, to measure the flow speed by throwing a wooden board from the bow of a ship, and then to calculate the distance in combination with the navigation clock produced in Houlong Village, and mark them on the chart one by one. Of course, the accuracy of the marine clock produced in Houlong Village is not very accurate, and the error of the clockwork clock is still very large.

When Wu Qing got the electronic watch, he was shocked and inexplicable, he was 100% sure that the gadget in his hand was definitely not a magic weapon, there was no trace of spiritual power fluctuations, but why the numbers on it kept changing, but he had no clue, if Wu Qing could still understand the clockwork clock, the electronic watch completely broke the confidence in his heart - Mr. Houlong Guo Dalu's deep knowledge is like the sea, like the grassland, it is not something he can imagine at all!

Wu Qing held the electronic watch and gritted his teeth gently, this time he ventured to Houlong Village, but he came to the right place!

Although Guo Dalu himself is not in Houlong Village, it is a great opportunity for him to save his wife's life and stay in Houlong Village.

What if Guo Dalu killed the Great Khan? The good men on the grassland cannot be killed! If you kill a Great Khan today, you will be able to set up a new Great Khan tomorrow, and there will never be a shortage of masters in the golden tent on the grassland.

But Guo Dalu didn't know that his big witch had already infiltrated his heart, lurking beside his most beloved family girl!

The Zhenyuan in the night sea, like a ghost, quietly crossed the sea, and Shi Xiaofeng, who had been watching from the bow of the ship, suddenly said: "Yizhou Island has arrived." "--The position of the lookout was originally on the mast, but the Zhenyuan has no sails, and naturally there is no mast, and the mast is set up on modern warships to install radar electronics, and there are no such tall things in the Zhenyuan Sea, so the deck is bare.

Chen Qingdai said: "The last time Mr. Shi fought with the Fanren pirates was in the dry port, it should be their lair, Mr. Shi may be able to identify the direction?"

Shi Xiaofeng stared, staring at the coastline in the dark night, he has also been to Yizhou Island many times, when the families developed Yizhou Island, they had asked Shi Xiaofeng to send warships to escort - of course, nominally a sailor training or something - he looked around for a while, and then pointed to the right: "A bag of cigarettes along the coast is a dry port." ”

Chen Qingdai waved his hand: "Install the stone thrower!" Previously, for the sake of the smooth navigation of the hull, there was no protruding stone thrower installed on the deck, at this time, the young soldiers and craftsmen were busy, and five stone throwers were erected on the deck in one go.

The Zhenyuan lowered a dinghy, measured the depth of the water in front of it, observed whether there were reefs, and slowly moved forward with a kerosene lamp with a cover on which only the exposed light could be seen from the opposite side. Previously, Shi Xiaofeng was because he didn't know the water and reef conditions, and as a result, most of the sailors' ships ran aground on the reef, which led to a big defeat.

There were a few lights ahead, and that was the fire that the pirates were heating up on the dock of the dry port.

Chen Qingdai showed a sneer on her face, death is coming, and you will soon enjoy the taste of hell!

The Zhenyuan retracted the boat, quietly slipped into the dry port, and slid between the large and small pirate ships, the sound of snoring, the nonsense in the dream, and the clamor of the drunken pirates came from the pirate ships on both sides, but no one noticed that there was an enemy warship, which had already infiltrated its side, like a tiger diving into a flock!

Chen Qingdai waved her hand, and the young soldiers immediately put a large clay pot on the catapult, which is an incendiary bomb, which is filled with gasoline, sugar, plastic belts cut into strips, etc., the best way to fight at sea is to attack with fire, Chen Qingdai must set a good fire!

At such a close distance, Chen Qingdai did not test shoot at all, and if she missed the shot, the young soldier in charge of aiming and shooting directly took a piece of tofu and hit her head.

Chen Qingdai waved her hand, boom, boom, the cantilever of the five stone throwers was raised high, and the incendiary bombs were thrown out one by one, and after the five clay pots smashed into the five largest pirate ships, there was a slight explosion, and the boom burned - in order to ensure the success of the operation, Chen Qingdai secretly violated the agreement with the big girl in advance to "not use weapons other than black powder", and installed a fire ****, which can explode on impact, so as not to ignite the fuse of the clay pot and expose her position in the dark night.

Chen Qingdai's battle plan proved to be extremely successful, and when the five pirate ships caught fire, none of the pirates found out that they had been attacked, and they thought that a drunken drunkard had inadvertently lit the fire and clamored to come to put out the fire.

However, this fire was extremely strange, the pirates poured water on it, and the fire burned more and more, and it was useless to cover it with sand, and some pirates beat it with a mop, and accidentally splashed sparks on their bodies, and suddenly screamed, and the fire actually burned on the flesh! The pirates next to him hurriedly threw themselves with their hands, but they did not expect their own hands to burn, even if they dipped their hands in the bucket, the fire would not be extinguished!

The pirates exclaimed, "Hellfire, hellfire, this is a fire from hell that will never be extinguished! God, I said a long time ago, we should not come to this infidel island, we are cursed!"

Chen Qingdai was still firing incendiary bombs, as more and more pirate ships around were ignited, with the help of the light of the flames, the speed of the young soldiers' shooting was accelerated, and the shooting accuracy was also more accurate, and some incendiary bombs smashed directly into the pirate crowd who were fighting the fire, turning them into candles.

Eventually, some pirates spotted the strange ships in the harbor, and they shouted, "The infidels have invaded! attack!

Those pirate ships that were not on fire threw black powder shells at the Zhenyuan - I have to admit that the pirates are also very studious, a few days ago on the pirate ship captured by Chen Qingdai, there were a few pirates with good water quality, quietly jumped into the sea and swam back to Yizhou Island, bringing back the news of the iron kettle that would explode. The pirates quickly followed suit and made iron-clad shells.

The pirates fired in a hurry, and the iron-hulled shells exploded on the outside of the ship, leaving only a black mark on the copper skin. A few iron shells fell on the deck, but everyone on the Zhenyuan had already prepared, wearing heavy armor, although it was a little inconvenient to move, but the fragments of the iron shell after the explosion of black powder smashed on the heavy armor, Ding Dang could only smash out a few shallow pits, but could not penetrate the armor - the pirates only learned a shape, but did not make any prefabricated fragments, after the explosion of the iron shell, it could only be split into several pieces.

There were even a few bold young soldiers and soldiers, such as Gou Buli and Chen A-bian, who picked up the iron-shelled shells that were rolling on the four boards, pulled out the fuse that was still burning, and threw them back into the sea.

At this moment, in a wine and dinner at the dock of the dry port, several pirates rushed in: "Jack, Priest Jack, damn it! We are under attack! Fight back with your spells!" (To be continued.) )
