After dealing with Wu Bao 'er and her gang, Zhou Qingfeng followed Guo Jiao back to the city to visit Guo Buyi. He was moving to Lushun, and Guo Buyi wouldn't foolishly stay in Fushun to wait for Nurhachi to come knocking on his door.
Especially now that Zhou Qingfeng had made Guo Buyi a "money-making treasure", Guo Buyi wanted to leave even more than Zhou Qingfeng. However, the Guo family was small in number and had a large family business, so they needed Zhou Qingfeng's help to move. Guo Buyi couldn't carry the family on his shoulders alone no matter how capable he was.
Zhou Qingfeng suggested that Guo Buyi take the water route to the camp. Guo Buyi flipped open his own map and pointed to the estuary of the Liao River. "You're talking about the Liang Fang Kou, right? When I first came to Liaodong, I followed the river to familiarize myself with the geography. The east side of the estuary is high, and the west side is flat. The river is curved, and the river is deep and wide. I vaguely think that there aren't many people there, so it's a good place to stay temporarily. "
Guo Buyi's map was drawn by himself. Although it was very rough, the general geography was correct. Zhou Qingfeng said in a low voice, "Senior, can I borrow your flying boat and ask Sister Guo Jiao to accompany me to the Liang Fang Kou. I want to survey the geography there. "
Flying in the sky was better than running on the ground, but the flying boat could only be used if one's Vitality was at least Stage Six, so Zhou Qingfeng had to bring Guo Jiao with him. Guo Buyi had no objections to this. He took out an ivory boat model from his storage pouch and handed it over to Guo Jiao. Then, he ordered his daughter to bring Zhou Qingfeng on a trip.
Seeing the shape of the boat, Zhou Qingfeng's obsessive-compulsive disorder kicked in. He couldn't help but ask, "Senior, can you modify this flying boat a little? If you want to fly in the sky, this boat-like appearance is not aerodynamic. "
Guo Jiao rolled her eyes at Zhou Qingfeng, and Guo Buyi also put on a cold face — I know you are capable, but can you not always say that my things are bad? He even purposely acted as if he wanted to give me some pointers. In any case, I'm still a Master of Traps and Spells. You're really annoying!
"What are you trying to say?" Guo Buyi asked impatiently. He knew that Zhou Qingfeng was weird. If he didn't get to the bottom of it, he wouldn't feel comfortable holding it in.
"I mean, can this flying boat not be made into a boat? It's better to change it into a bird." Zhou Qingfeng was just spouting nonsense. How could he possibly understand something as profound as aerodynamics? He was just used to seeing airplanes, so he was very unhappy with Guo Buyi's flying boat — this thing didn't even have wings, it was too unscientific.
Guo Jiao felt that Zhou Qingfeng's words made sense, so she asked Guo Buyi, "Dad, Little Zhou is right. Why don't you make it into a bird? Why do you have to make it into a boat? Maybe it can fly faster if it's a bird. I also think that this flying boat is too slow. "
"Hmph … What do you know? Flying boats have always been like this since ancient times. If it's not made into a boat, how can it be called a flying boat? "Guo Buyi took the flying boat from his daughter's hands, and blamed Zhou Qingfeng for being a busybody.
Zhou Qingfeng was thick-skinned, and said, "Maybe we can call for a plane. Make it into two straight wings, and a pointy head. " He was so excited that he took out a pen and paper from his storage bag, and casually drew an ugly monoplane. Later, he felt that a monoplane might be too advanced, so he changed it to two wings, and even added three wheels under the wings.
Seeing this strange drawing, Guo Buyi was immediately annoyed. "If I fly this thing in front of my peers in the future, I'll be laughed at." After saying that, he threw the flying boat to Guo Jiao, and said, "Use it or not, don't make so many demands."
Guo Buyi flicked his sleeves, and returned to the quiet room at home to rest, leaving Zhou Qingfeng and his daughter staring at each other. However, he was a person who believed in leaving a way out, so when he left, he secretly sent a voice transmission to his daughter, "Accompany this kid to my refining room. Every time this kid comes up with a strange idea, I want to know what he wants to do."
As soon as Guo Buyi left, Guo Jiao turned to Zhou Qingfeng with a sly smile, waved her hand, and shouted, "Kid, come with me."
Zhou Qingfeng couldn't resist the temptation of women. When he saw sister Guo Jiao's bright smile, he thought that he had won the favor of the big sister, and immediately followed her. The two entered Guo Buyi's refining room, which was very different from the alchemy room. A huge workbench was placed in the room, and several puppet assistants stood in the corner.
Guo Jiao pulled Zhou Qingfeng to the workbench, and said, "Come, little refiner, try your skills. Make a flying boat that you want, and let me see it. I also want to know what good things you can make this time. "
"Me?" Zhou Qingfeng immediately put on a bitter face, "I only know how to think, but I don't know how to do it."
No one knew where Guo Buyi was hiding, but he secretly transmitted his voice to Guo Jiao, "Just let him think. This kid has a lot of tricks, and each of his ideas is ingenious. Father, I don't have the face to ask him, so it's better if you ask him. What he said about a plane with wings seems to make sense, right? "
"Father, you're so bad!" Guo Jiao secretly said. She took out a set of flying boat blueprints from a big cabinet in the refining room, and with a wave of her hand, a phantom image was projected on the workbench. Zhou Qingfeng looked at it carefully, and this phantom image was the blueprint of the flying boat. Guo Jiao chuckled, "You tell me, I'll change it."
She wanted Zhou Qingfeng to be an aircraft designer, but he was very clear that designing an aircraft required a very professional ability. After hesitating for a while, he said, "First, tell me, how does this flying boat fly?"
"It's lifted by the wind." Guo Jiao said with a tone that said 'you already know the answer', "Do you really not know? Don't birds fly like this? "
Oh my god! Birds don't fly like this.
Forcefully using the wind to lift a boat in the sky? No wonder you guys need Qi and blood Stage Six to be able to control this thing. So you guys used the dumbest and dumbest method to build the flying boat.
Zhou Qingfeng could not tell Guo Jiao about the Bernoulli principle of fluid mechanics, but in his heart, he was very confident that he could build a better aircraft. After thinking for a while, he said to Guo Jiao, "Sister, wait for me for a while, I'll go back and find something before coming back." After saying this, he hurriedly left the Guo family's study and returned to the Lin family's inn in the west of the city.
Guo Buyi's figure suddenly appeared beside Guo Jiao, and he also said inexplicably, "What the hell is this kid up to now? Could it be that he can really make something better than my flying boat? This is the best model that the forging masters of the past generations have put their blood, sweat, and tears into making. Do you think that he can surpass it with a few words of nonsense? "
Guo Jiao chuckled softly, "If Father wants to know, why don't you sneak over and take a look? Maybe you can learn something from him. "
Guo Buyi was more casual in front of his daughter, and he proudly said, "I'm a knowledgeable person with a belly full of skills, why would I do something like that? That kid is going to give me the secret skill himself, and I'm just going to take a look, I don't want to learn it. "
Guo Jiao laughed out loud, and she punched Guo Buyi's back with her pink fist. Guo Buyi also felt that he was old and pretentious, and he laughed at himself. Not long after the father and daughter laughed, Zhou Qingfeng ran back happily, and there were a few more drawings in his hand.
"I want to ask first, how strong is the wind that you used to lift the flying boat, Senior?" When Zhou Qingfeng returned, he saw that Guo Buyi was also there, so he first used a piece of paper to demonstrate the phenomenon of air pressure difference caused by air flow, and then began to ask questions.
"The strength of the wind?" When it came to the specific technology, Guo Buyi also became more serious. He held the flying boat model in his hand and said, "Since ancient times, the sages have observed the flight of birds, and also wanted to fly in the sky.
Generations of weapon forging masters pondered over this, and came up with a way to make a boat, and the bottom of the boat would eject air to lift the body of the boat. Because the boat is very heavy, it also requires a high cultivation level for the pilot. This boat must be light, and can only carry three people at most. The full weight is about 800 jin. Any more and it won't be able to fly. As for how strong the wind is? It's the strength of the wind that can be continuously cast. "
Continuously casting the Wild Wind Spell?
Zhou Qingfeng scratched his head, and felt that it was better to be more conservative. He took out a copy of the drawing, and pointed at the plane with three layers of wings, and said, "Build it according to this. This is the easiest. "
This was a copy of the 'Fokker DR-1' triplane from an old aviation magazine, and it was the main character of the 'Fokker Disaster' during World War I. The famous' Red Baron 'flew it in the sky, and made a name for himself in the history books. Zhou Qingfeng marked the rough size on the copy of the drawing, so that people could feel the actual size of the plane.
Because the engine power during World War I was not high, the 'Fokker DR-1's' empty weight was only 400 kg, and the maximum takeoff weight was only 580 kg. It was very small.
Guo Jiao came over to take a look, and after some estimation, she modified the original shape of the flying boat, and at the same time raised a question, "What are the two blade-like things in front of the plane?"
"Hmm …, this thing doesn't need it," Zhou Qingfeng said that he would remove the propellers, and change the blunt end of the plane into a pointed end, to reduce the drag. "Note that the tail rudder and wings can be controlled, and they determine the pitch and left and right of the flight. It's best if the wheels can be made into something that can be stored, and released during takeoff and landing, and retracted after takeoff to reduce the drag. "
The two rookie aircraft designers struggled for two hours, and barely managed to make the 'Fokker DR-1's' outer appearance look decent. After Guo Jiao was done, she cried out in joy, and immediately ordered the puppet assistant in the refining room to carve a scaled-down model.
The puppet assistant moved quickly, and used a piece of wood to carve parts to assemble the model of the plane. After it was assembled, Zhou Qingfeng used a rope to hang the model, and then used the Gale Spell to blow at the model. Under the blowing of the airflow, the relatively reasonable wing structure allowed the model to fly by itself. At least it showed that there was no problem with the shape of the plane.
Guo Jiao, who was involved, was even more excited than Zhou Qingfeng, and could not wait to make a real plane for testing. Making a real plane was not difficult. The puppet assistant spent a day, and used the light and sturdy Ferric Wood to complete the entire body. Guo Jiao then used a spell to strengthen the structure of the body, to ensure that it would not fall apart. In the end, the weight of the body was much lighter than expected.
However, what came next was a problem …
"Uh … Do I need to find a power core for this plane?" Zhou Qingfeng was very satisfied with the appearance of the plane, but how could he make this thing fly? "I need to find something to create the airflow that blows. What's the thing that creates the Gale Spell on the flying ship? "
"It's not easy to continuously create a gale. My father's flying ship relies on a formation plate that costs fifty thousand taels. No one usually wants this thing, and it's too expensive, so my father found someone to make it. "Guo Jiao was also troubled by the problem of not having any power, as if someone had poured a bucket of cold water on her head.
Power had always been a difficult problem, and it was really not easy to solve.
Zhou Qingfeng and Guo Jiao looked at each other, and a sigh came from outside the refining room.
Guo Buyi appeared at the door with a small piece of paper in his hand. With a light blow, the paper floated up due to the difference in pressure. He then frowned and looked at the completed plane. "Such an ugly thing, and it can actually fly just by blowing? Generations of sages have pondered over this for one to two thousand years, and the theory is so simple. "
The new generation replaces the old, and the new generation replaces the old.
