See! There is a! ——

The fuselage of an airplane is actually not difficult to build, for example, during World War I and World War II, there were many wooden frame planes flying in the sky. The biplane wooden aircraft is not too much of a problem for Sun Yu to make a shell now.

But the key problem is the "engine", the "engine" of the aircraft can be said to be its soul, it must be light, but also powerful, and lightness and power are two contradictory problems. Generally speaking, the lighter the engine, the less power it will have. The more powerful the engine, the heavier it will be.

With the technological prowess of the Three Kingdoms period, it was impossible to build an engine that could drive a biplane wooden airplane.

Fortunately, this world is not exactly the Three Kingdoms, in this world, in addition to the engine, there is another thing that can provide kinetic energy for the aircraft, that is, the god of work.

"The whole army is stationed at the mouth of Mingyue Gorge, set up camps, and prepare for air defense." Sun Yu ordered loudly, and Ma Chao, Ma Dai, and Pang De, who were the vanguards in front, all retreated from the Mingyue Gorge plank road and merged into the Chinese army. Not long after, the grain and grass army also caught up from behind, and the three armies merged to establish a very huge camp.

This camp is held on the opening of the Mingyue Gorge plank road, and many anti-aircraft canopies are built in the stockade with wood, which are very short and the top cover is particularly strong, allowing soldiers to hide in it to resist bows and arrows from the sky. A large number of bows and arrows and a repeater machine jointly invented by Zhuge Liang and Huang Yueying were prepared in the camp, ready to deal with the Wudang flying army from the sky at any time.

In this way, the Wudang Fei Army of only 2,000 people did not dare to attack again, Wang Ping and Xiahou Yuan simply built a camp on the top of the Mingshan Gorge, condescendingly, looking down on the camp of the Gongsun Army.

The Wudang Flying Army sent people to monitor the Mingyue Gorge Plank Road at night, and if any of the Gongsun Army's people tried to sneak past the plank road, they would send the Flying Army to carry out an air attack at any time.

However, Sun Yu did not plan to sneak through the plank road with any conspiracy, but planned to hit the sky in a dignified manner. He sent little Zhao Yun to ride the jade lion horse to the blacksmith shop in Chengdu at full speed to pick up Huang Yueying, and he himself spread out the four treasures of the study in the camp tent and carefully painted the two-winged wooden plane.

Xiao Zhaoyun went to Chengdu and went back and forth, it always took a few days, and these days could also allow the soldiers to rest and recuperate, and they didn't have to be too nervous to draw their own aircraft maps, and they could work slowly and carefully.

"Seek the truth, what is this thing you draw?" Soft girls look strange.

Sun Yu smiled: "Well...... It's something that can make people fly into the sky......"

"Wow, you're so good." The soft girl has long had a certain habit and immunity to Sun Yu's endless abilities, but when she heard that he could make people fly, she was still a little surprised.

"Well...... This may not be successful, don't tell anyone, otherwise I will lose face if I fail. ”

"Uh-huh, I don't tell anyone." The soft girl said softly: "There is a girl named Xucai living in your jade seal, and I haven't told anyone about it." ”

"My soft girl is the most well-behaved." Sun Yu hugged her gently.

At this time, a soldier outside the camp tent reported: "Lord, General Sun...... Zhuge Junshi took Jiang Wei and asked to see him. ”

"Leading?" Sun Yu was so annoyed by this strange verb.

The soft girl didn't care about this kind of subsection, and said softly outside the tent: "Please." ”

I saw Zhuge Liang in a robe walking in with a hippie smile, she was holding a hemp rope in her hand, and behind the rope was Jiang Wei, who was tied like a rice dumpling, but Jiang Wei's feet were not tied, so that she could walk by herself, Zhuge Liang dragged her with a rope like a puppy.

"What are you...... Why? "Sun Yu Khan.

Zhuge Liang shrugged his shoulders: "This guy is always tied up and thrown in the camp tent, I am afraid that the flow of qi and blood in her body will not be smooth, which is not conducive to her health, so I will take her out and walk around a few times......"

I'm sweaty, and I'm really a walking dog.

"Well, don't worry about this kind of subsection." Zhuge Liang said seriously: "I came to ask you what method you plan to use to pass the Mingyue Gorge plank road." ”

Before she could say anything, Jiang Wei behind her hurriedly spoke: "Small-grown freaks, stinky rascals, you were scared by General Wang Ping's flying army, right?" Hahaha, you can't get through this Mingyue Gorge plank road, if you want to invade Hanzhong, no way! ”

"Shut up, I didn't tell you to speak." Zhuge Liang glared at Jiang Wei, and then said viciously: "Don't think that our army can't cross the gorge, we just need to transfer my sister Pang Tong, use her 'Hundred Miles Chain' plus the 'Bow King' to find the truth, and ten thousand bow kings will release arrows together, and Xiahou Yuan and Wang Ping will be shot into hedgehogs and planted from the sky as soon as they meet." ”

As soon as she said this, Jiang Wei's face suddenly changed greatly, just now he was talking nonsense, but now he can't say a word, obviously frightened by the strategy proposed by the female hooligan, and 10,000 "Bow King" volleys are fired...... It's creepy to think about.

However, Zhuge Liang also knew that this strategy was vetoed by Sun Yu last time, Xiahou Yuan was indeed not an enemy general who should be killed, Zhuge Liang also agreed, she just said it to scare Jiang Wei, seeing that the little sister was frightened by herself, she smiled and reached out and touched Jiang Wei's chin and said, "But...... We don't want to use this strategy for the time being. Because Xiahou Yuan and Wang Ping are both beauties, this kind of woman has to be caught and whitewashed and enjoyed, and she can't be killed casually, it's too wasteful. ”

"Demons, beasts, perverted ......" The little sister began to scold again: "General Xiahou Yuan is a surname who would rather bend than bend, she would rather be shot to death than be humiliated by you." ”

"Oh? Can this sentence be understood as that he would rather bend than bend, but you would rather bend than bend, and you are more willing to be humiliated than die? Zhuge Liang stared at Jiang Wei with a wicked smile.

"Fart!" The little sister said loudly: "I'd rather die than be humiliated, if you cut my shirt again, or let Sun Yu touch my chest again, I will bite my tongue and kill myself, don't think I'll be at your mercy." ”

"Alright, stop making trouble!" Sun Yu hurriedly interrupted the words of the two, shrugged his shoulders and said, "I'm thinking of a new weapon that can win even if I don't use the Hundred Miles Link and the Bow King...... It's just that it's still in the design stage, and I've already sent Xiaoyun to pick up Huang Yueying, it's not too far from Chengdu, and the jade lion runs fast in the night, and it can be reached in a few days. ”

Zhuge Liang's eyes suddenly lit up, after she met Sun Yu, she had already seen several things designed by Sun Yu, during the Battle of Xuzhou, Sun Yu designed a new type of thunderbolt car, blocking Liu Ye's thunderbolt car outside Xuzhou City, famous all over the world. In the Battle of Hanshui, Sun Yu designed a variety of new warships and defeated Liu Biao's army. This new type of warship was even recognized by Jiangdong, who spent a lot of grain to exchange technology with the Gongsun army.

Siege warfare, water warfare, Sun Yu has a good performance, this time Sun Yu is going to intervene in air combat again?

Zhuge Liang himself is also an inventor, and he is very interested in inventing various tools, and when he heard that Sun Yu was going to invent weapons for air combat, he immediately came to the momentum, and she brushed the floor to Sun Yu's desk and leaned over to look at the drawings on the table.

But no matter how talented Zhuge Liang is, it is impossible for him to understand such a thing as aerodynamics, and she has been watching it for a long time, but she can't see anything surprising about the design of the biplane wooden aircraft. What are the wings and tail used for? Can this wooden shelf fly in the sky? Why? I don't understand!

"I thought you designed a big wooden bird that could fly in the sky with its wings, but what are you? It's not like a bird! Zhuge Liang is a little confused, in fact, the ancient Chinese have carried out some research on flight, and some folklore often says that Master Luban made a "wooden harrier", which is shaped like a bird and can fly in the sky with wings, so Sun Yu said that he could make a weapon that flew in the sky, Zhuge Liang was not surprised, she also thought that Sun Yu knew how to make the legendary wooden harrier.

But when you look at the design drawings, where is this a wooden harrier? It's like a double-walled wooden hanger, can this thing fly? Zhuge Liang was a little confused.

Sun Yu smiled and said, "This thing is like this...... You see, we used Huang Yueying's 'Gongshen' to give this thing a huge force to rush forward...... It rushes forward, then the air ahead ...... Belch...... That is, the wind, which will give it the force that has always acted in the opposite direction......"

As soon as Sun Yu opened his mouth, he heard Zhuge Liang, Soft Girl, and Jiang Wei dizzy together.

"The way this wing is made is exquisite, it is the result of the study of aerodynamics, when it rushes forward against the air, the air will give it a force to lift up, and then ...... It will send the whole plane into the sky...... This rear wing is used to adjust the balance and rise and fall, and it can control the direction of air flow by changing the angle, changing the force of rising and descending. Sun Yu pointed to the wings and said seriously.

"Ahem...... Seeking Truth ...... I don't quite understand that. Zhuge Liang wiped a handful of sweat.

The little sister Jiang Wei snorted coldly, and laughed strangely: "It's nonsense, if you want to fly like this, it's just a fool's dream, and I laughed to death......"

The soft girl next to her didn't understand, but the soft girl trusted Sun Yu unconditionally, she stood behind Sun Yu and said very seriously: "If you can fly, you will definitely be able to fly, you don't need to doubt it." ”

"Cut!" The little sister snorted disdainfully, the child in the rebellious period is like this, she refuses to believe what the adults say, and she will think that the adults are all wrong, and only she is right.

Sun Yu didn't bother to pay attention to her, and buried himself in drawing drawings again.

At this time, Zhuge Liang suddenly smiled: "Looking for the truth, I actually have a small matter to deal with when I brought Jiang Wei here." ”

"What's the matter?" Sun Yu asked curiously.

Zhuge Liang smiled, turned his head to Jiang Wei and said, "Little girl, do you have the courage to compare with me who has more military talent?" ”

"Of course I have the guts!" The little sister will not admit defeat.

Zhuge Liang stretched out his hand and pointed to a sand table that Sun Yu placed in the big tent of the Chinese army, and said with a wicked smile: "Okay, then the two of us are here, doing military exercises in front of the lord and General Sun, and if you lose a game, you will take off a piece of clothing, and whoever takes off naked first will lose." ”
