dealt with Wu Bao'er and his gang simply and neatly, and Zhou Qingfeng followed Guo Jiao back to the city to visit Guo Budo. He wants to move to Lushun, and Guo Budo will not stay in Fushun stupidly and wait for Nurhachi to come to the door.

Especially now that Zhou Qingfeng pulled Guo Budo to make a 'money-making treasure' on the platform, Guo Budo wanted to leave more than Zhou Qingfeng. However, the Guo family has a small population and a large family business, and they need Zhou Qingfeng's help to move away - relying on Guo Budo alone, no matter how big his ability is, he can't carry the family on his shoulders.

Zhou Qingfeng suggested that Guo Budo go to Yingkou by water, Guo Budo opened a map of his own, pointed to the mouth of the Liao River and said, "You are talking about Liangfangkou." When I first arrived in Liaodong, I was familiar with the geography along the river, which is surrounded by high mountains in the east and flat in the west, with a curved river channel and a deep and wide sea. I vaguely think about it, where there are no people, it is appropriate to occupy a temporary foothold. ”

Guo Budo's map was drawn by himself, and although it was crude, the general geographical environment was correct. Zhou Qingfeng said in a deep voice: "Senior, can you borrow your flying boat for use, and then ask Sister Guo Jiao to accompany me to this Liangfangkou." Where am I going to survey the geography. ”

Flying from the sky is better than running on the ground, but the flying boat can only be used with more than six layers of qi and blood, and Zhou Qingfeng must pull Guo Jiao to do it. Guo Budo had no objection to this, he took out an ivory carved model of the boat from his storage bag and handed it to Guo Jiao, telling his daughter to take Zhou Qingfeng for a run.

Seeing the shape of the boat, Zhou Qingfeng's obsessive-compulsive disorder was committed. He really couldn't help but ask: "Senior, can this flying boat transform one or two?" If you want to fly in the sky, the ship-like appearance is not aerodynamic. ”

Guo Jiao threw Zhou Qingfeng a roll of his eyes, and Guo Budo also put on an indifferent face - the old man knows that your kid is capable, but can you not say that the old man's things are bad every time? He also deliberately put on a tone to point me out. The old man is also a master of tricks, you kid is really annoying!

"What the hell are you going to say?" Guo Budo asked angrily. He knew that Zhou Qingfeng was weird, and if he didn't ask clearly, he would feel uncomfortable.

"I mean, can this flying boat not be made into the shape of a boat, and it is better to change it to the shape of a flying bird." Zhou Qingfeng is actually nonsense, how can he understand such a profound thing as 'aerodynamics'? He is used to watching airplanes, and he is very unhappy to see Guo Budo's flying boat - this thing doesn't even have wings, it's too unscientific.

Guo Jiao felt that what Zhou Qingfeng said was a little reasonable, so she asked Guo Budo rhetorically: "Dad, what Zhou Xiaozi said is also right, why don't you make a bird's appearance, you have to make a boat?" Maybe you can make a bird fly faster. I also think this flying boat is too slow. ”

"Hmph......, what do you know? Since ancient times, flying boats have been like this. If you don't make it look like a boat, how can you call it a flying boat? Guo Budo took back the flying boat from his daughter, and blamed Zhou Qingfeng for being troublesome.

Zhou Qingfeng was thick-skinned and said, "Xing is allowed to call a plane." Make two straight wings with pointed heads. He said vigorously, and simply took out a pen and paper from his storage bag and drew an ugly monoplane shape. Later, he realized that the single wing was too advanced, so he changed to a double wing, and even added three wheels under the wing.

Seeing this strange-looking drawing, Guo Budo immediately became angry, "If Guo drives this thing to fly in front of his colleagues in the future, he will be laughed to death." After speaking, he threw the flying boat to Guo Jiao and said, "If you like to use it, don't ask for so much." ”

Guo Budo brushed his sleeves and left, returned to his home to rest in the quiet room, leaving Zhou Qingfeng and his daughter staring at each other. However, he believes in 'leaving a line in everything', and when he left, he secretly said to his daughter: "You accompany this kid to my refining room, this kid must have something to gain every time he makes a whimsy, I want to know what he wants to do?" ”

As soon as Guo Budo left, Guo Jiao smiled slyly at Zhou Qingfeng in a blink of an eye, waved his hand and shouted, "Boy, follow me." ”

Zhou Qingfeng couldn't stand the temptation of women the most, and when he saw Guo Jiao's sister's smiling eyes, he thought that he had won the favor of the royal sister with a shock to his tiger body, and immediately followed him. The two of them entered Guo Budo's refining room, which was very different from the layout of the Dan room, with a huge workbench in the room and several puppet assistants standing in the corner.

Guo Jiao pulled Zhou Qingfeng to the workbench and said, "Come, little refiner, you can try your skills." Make a flying boat you want for me to see. I'd also like to know what good stuff you're going to be able to make this time. ”

"Me?" Zhou Qingfeng suddenly put on a bitter gourd face, "I can only think about it, I won't do it." ”

Guo Budo didn't know where to hide, so he secretly transmitted the voice and Guo Jiao said: "You just let him think." This kid has a lot of ways, and he thinks a lot of ingenuity. Daddy, I can't pull my face to ask him, you can ask better. What he said about airplanes with wings, it seems that there is some truth in it? ”

"Daddy, you're so bad!" Guo Jiao said secretly. She took out a set of drawings of the flying boat from a large cabinet in the refining room, and with a stroke of her hand, a phantom image was projected on the workbench. Zhou Qingfeng looked at it, and this phantom was the structure diagram of the flying boat. Guo Jiao chuckled: "You come, I'll change it." ”

This is to let Zhou Qingfeng be an aircraft designer, but he knows very well that designing a flying machine requires very professional ability, and after a while, he said: "You tell me first, how did this flying boat fly?" ”

"It's held up by the wind." Guo Jiao had a 'you knowingly asked' tone, "Don't you really know?" Don't birds fly like this? ”

Oh, my God! That's not how birds fly.

Hold a ship in the sky with the wind? No wonder you have to have six layers of qi and blood to control this thing. It turns out that you built the flying boat in the stupidest and stupidest way.

Zhou Qingfeng couldn't tell Guo Jiao about the 'Bernoulli principle' of fluid mechanics, but his confidence in building a better flying machine was greatly increased. After pondering for a while, he said to Guo Jiao: "Sister, you are waiting for me for a while, and then I'll go back and find something." After he finished speaking, he hurriedly left the Guo family bookstore and returned to the Lin family inn in the west of the city.

Guo Budo's figure suddenly appeared beside Guo Jiao, and he said inexplicably: "What the hell is this kid going to do?" Could it be that he can really make something better than my flying boat? This is the best style that everyone has worked hard to make in the past generations, and he can surpass it with a few words of nonsense? ”

Guo Jiao chuckled softly: "If Daddy wants to know, why don't you secretly follow over and take a look?" Maybe you'll learn a few tricks. ”

Guo Budo was also more casual in front of his daughter, and said proudly: "Guo is rich in five cars and full of skills, why do you need to do that stealing teacher?" That kid is going to send the secret technique himself, I'm just going to see it, I don't want to learn it yet. ”

Guo Jiao was so happy that she couldn't support her laughter, and she came to beat Guo Budo's back with a pink fist. Guo Budo also felt that he was hypocritical when he was old, and laughed self-deprecatingly. And not long after their father and daughter laughed, Zhou Qingfeng ran back happily with a few more drawings and drafts in his hand.

"I want to ask first, the predecessors used the wind to support the boat, how strong is the wind?" Zhou Qingfeng came back and saw that Guo Budo was also there, and first used a note 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 comes to specific technologies, Guo Budo is also a little serious. Holding the model of the flying boat in his hand, he said: "Since ancient times, the sages observed the flight of birds, and also wanted to be able to fly in the air.

The master refiners pondered this matter and came up with a way to make a boat and spew air currents from the bottom of the ship to lift the hull up. Because the ship is very heavy, the cultivation of the person who controls it is also extremely demanding. The boat had to be light and carry a maximum of three people. The total weight of the full load is about 800 catties. No matter how much it is, it won't be able to fly. As for how strong the wind is? It's the strength of the Wind Technique. ”

Constantly performing the Temporal Technique?

Zhou Qingfeng scratched his head, feeling that it was better for him to be conservative. He pulled out a copy of the drawing, pointed to the plane with three wings on it, and said, "Let's build it according to this." This one is the easiest. ”

This is the 'Fokker Dr-1' triplane copied from an old aviation magazine, which was the protagonist of the 'Fokker disaster' during World War I. The famous 'Red Baron' is the name that went down in history when he drove it in the sky. Zhou Qingfeng marked the approximate size on the drawings he copied, which can make people feel the actual size of this aircraft.

Due to the lack of engine power during the First World War, the empty weight of the Fokker Dr-1 was only 400 kilograms, and the maximum take-off weight was only 580 kilograms. Very small.

Guo Jiao came over to take a look, and after estimating it, she modified the shape of the original flying boat, and also asked, "What are the two blade-like things in front of this plane?" ”

"Well...... this thing doesn't want it." Zhou Qingfeng said that the propellers were removed, and the blunt end of the aircraft was turned into a pointed end to reduce drag. "Note that the rudder and the wings are maneuverable, and they determine the pitch and left and right of the flight. It is best to make these wheels retractable, release them during take-off and landing, and retract them after take-off to reduce drag. ”

The two rookie aircraft designers tossed around for an hour, barely making the appearance of the 'Fokker Dr-1' look decent. Guo Jiao shouted happily after completion, and ordered the puppet assistant in the refining room to carve a scaled-down model on the spot.

The puppet assistant moves quickly, assembling a model of an airplane from a piece of wood carved pieces. After spelling it out, Zhou Qingfeng hung the model with a rope, and then blew on the model with the wind technique. Under the blowing of the air current, the relatively reasonable wing structure allows the model to fly on its own. At least it shows that the shape of the plane is fine.

Guo Jiao, who participated in it, was even more excited than Zhou Qingfeng, and couldn't wait to build a real machine for testing. It's not hard to build a real machine. The puppet assistant spent a day completing the entire fuselage with lightweight, sturdy ironwood. Guo Jiao then used magic to strengthen the structure of the body to ensure that it would not fall apart casually. In the end, the weight of the fuselage was much lighter than expected.

But then came the trouble......

"Uh......, am I going to find a power core for this plane?" Zhou Qingfeng is very satisfied with the appearance of the real machine, but how can he make this thing fly? "I'm going to find something to create a whistling airflow. What is it that produces the wind spell on the flying boat? ”

"It's not easy to constantly generate strong winds, and my father's flying boat relies on a formation plate worth 50,000 taels. This thing is usually not wanted, and the price is too expensive, so my father asked someone to order it. Guo Jiao was also trapped by the problem of no motivation, as if someone had poured a bucket of cold water on her head.

Motivation has always been a problem, and it's really hard to solve.

Zhou Qingfeng and Guo Jiao looked at each other, and a sigh came from outside the refining room.

Guo Budo appeared at the door with a small note in his hand. With a slight blow, the paper floats up due to the unequal pressure on the upper and lower levels. He frowned again and looked at the built plane, "Such an ugly thing, it can really fly by blowing?" The sages of the past generations pondered for one or two thousand years, and the truth was so simple. ”

The back waves of the Yangtze River push the front waves, and a new generation replaces the old.

"Guo has studied it all his life, but it is not as good as a small note." Guo Budo sighed melancholy, feeling that the world was so unfair - Zhou Qingfeng, this kid was too hateful.
