"It's flying!"

"Oh my God!

"What is this? How have I never seen it? But a legendary artifact?"

Looking at Liu Chu, who was standing in the air, everyone opened their mouths in surprise, this scene had a huge impact on them.

Flying, this is what human beings dream of, and only those who are close to immortals, that is, the powerhouses of the Three Realms of Taixu, have the ability to fly in the sky, but it is only short-lived. In addition, if humans want to fly, they can only rely on flying spirit animals.

"What an unexpected guy. Su Qin's eyes were also full of surprise and appreciation.

High in the air, Liu Chu smiled, his idea came true, this thing, if it can be mass-produced and put into use, it will change the whole world!

Between two points, the straight-line distance is undoubtedly the shortest, with the aircraft, in terms of cargo transportation, you can save a lot of time and cost, no need to bypass some difficult mountain roads, with the aircraft, the war will also be redefined, the archer can throw feather arrows down in the air, the air is an excellent commanding height!

Commercial, Civil, Warfare...... In every field, there will be earth-shaking changes!

"Still, it's better not to show up in large quantities, at least not yet. ”

Nowadays, Wei is a little young in terms of talents, and the new batch of young people has not yet grown up, and there will be a big shock in the future, and it is not a good time to put the aircraft into use in batches.

If the aircraft falls into the hands of other countries, other countries will conduct research and equip them in the army, once they are equipped, they will take advantage of the great earthquake of Wei to attack, and Wei will definitely suffer a fatal blow.

"It's going to be ruined when you go up for a while. Liu Chu whispered to himself and made a decision.

Above the top of the mountain.

"Alright, second tube, I'll go first. The old dean patted Tong Zhenghai on the shoulder, jumped into the air and stepped into the air, and then disappeared into the distance.

The short-term flying ability of the powerhouse of the Three Realms of Taixu!

"Ahh

"But this kid is really a genius, accepting such a disciple will not disgrace my reputation, and he will be accepted as a disciple in a while. Tong Zhenghai looked at Liu Chu flying in the air, the more he looked at it, the more pleasing it became, and the more he looked at it, the more satisfied he became.

Liu Chu slowly flew towards the top of the mountain, and when he controlled the aircraft to the top of the mountain, he suddenly found that the shape of the mountain resembled a super big gourd.

Liu Chu saw two people standing on the top of the mountain, the first one was a middle-aged man, who looked a little rich and fat, with a big belly, and his eyebrows were quite kind.

But when he saw the young man standing next to the middle-aged man, Liu Chu was stunned, this was a little fat man, who looked meaty, and was waving at Liu Chu at the moment.

Tong Botao!

Liu Chu's head was full of question marks, why is this kid here? Could it be Tong Zhenghai's disciple?

"Tong Botao, Tong Tong, could it be that his real name is Tong Botao, and Tong Zhenghai is his father?" Liu Chuchu gave birth to a bold guess.

"Liu Chu, come down!" Tong Botao put his hands in front of his mouth and shouted at Liu Chu in the air.

Liu Chu controlled the aircraft and slowly landed on the top of the mountain, the wind driven by the huge wings blew Tong Zhenghai and Tong Botao's clothes hunting, and a few messy hairs on his forehead were blown out of his way.

"Why are you here?" After Liu Chu stopped the aircraft, he jumped off the aircraft and looked at Tong Botao with a puzzled expression.

"Hehe, this is my second uncle. Tong Botao pointed at Tong Zhenghai.

Liu Chu suddenly realized that it was not a father-son relationship, but an uncle-nephew relationship.

"You are hidden deep enough, Tong Tong, ordinary people really can't even think of going to the Tong family in Karakuri City. Liu Chu quipped.

"There's nothing wrong with being careful when you're out and about. Tong Botao scratched his head embarrassedly and lied to Liu Chu, which also made him feel a little guilty.

After Liu Chu learned about Tong Botao's situation, he turned to face Tong Zhenghai: "Student Liu Chu, meet the teacher." ”

"You built this machine?" Tong Zhenghai nodded slightly, and then tapped the surface of the aircraft with his fingers.

"Yes, it was made by students. Liu Chu nodded.

"How long did it take?

"It took 15 days to ideate, another 15 days to make the drawing, and then four days to make it, and my friends helped me when I did it. Liu Chu replied.

"Fifteen days, you only took fifteen days to conceive?" Tong Zhenghai gasped, fifteen days of thinking, he could make such a flying machine, he thought that Liu Chu had this idea a few years ago.

What Tong Zhenghai didn't know was that Liu Chu had this idea when he was a child, but he never put it into action.

If it weren't for a few more protective measures, Liu Chu would have been able to shorten the time by half.

At the point of the flying machine, there were several cloth bags, and inside were huge circular cloths sewn together by several pieces of cloth, and ropes were tied around the cloth with holes, and all the other ends of the ropes were tied together, leaving the longest rope out.

If the aircraft loses power or disintegrates and falls in mid-air, as long as the circular giant cloth in the cloth bag is opened, the long rope left behind is tied to oneself, and then jumps down, the circular giant cloth will open, and after being resisted by the air, it will hold the person up, and the descent speed will be slowed down.

Liu Chu initially called this thing the Escape Bag, but later found the name too awkward, and decided to rename it a parachute based on its shape like an open umbrella.

"What's the name of your machine, how many people can it ride?" Tong Zhenghai had an urge to try.

"It's called a flying machine, and now it should be fine to carry three people, and if I am given more time, I can strengthen its structure and power to the point where it can carry ten, or even dozens of people. Liu Chu said.

"Okay, you can take me up for a spin now!" Tong Zhenghai's eyes lit up, and he climbed onto the aircraft very consciously.

Seeing this, Tong Botao also hurriedly climbed onto the aircraft. The uncle and nephew just watched Liu Chu on the flying machine, waiting for him to come up and take them into the sky.

After Liu Chu was stunned for a moment, he also climbed onto the aircraft and said to Tong Zhenghai: "Teacher, this is very easy to operate, why don't you control it?" Just pull this hand stick, lift it up is to lift it into the air, press down to land, and swing left and right is to control the direction. ”

"What? it's so simple?" Tong Zhenghai was shocked, compared to Liu Chu's behavior of taking a short time to build this flying machine, Tong Zhenghai was even more surprised by this simple operation!

You must know that it took them several years to complete the idea and drawings just by doing the idea and drawings, and it was even the result of a group of people to discuss, but Liu Chu realized it alone, and it only took one month, including manufacturing, and it only took one month and four days.

Moreover, the first generation of aircraft they built required at least three people to operate at the same time, and the operation steps were extremely complicated.

But Liu Chu, pulling up is lifting, pressing down is landing, swaying left and right is controlling the direction, this is a fool's operation, so simple that a person with a normal IQ can get started immediately!

Tong Zhenghai began to doubt himself: fuck, is Lao Tzu qualified to be his master? How do you feel that his ingenuity research and development and construction strength is stronger than mine?

Tong Zhenghai pulled up the operating stick, and the two huge wings of the aircraft flapped with a whirl, and slowly lifted off with the three of them.

"What is your source of motivation?" Tong Zhenghai suddenly asked.

"At our feet, there's a gearbox, and when you pull it on the net, the gears in the gearbox are probably spinning thousands of times, providing tremendous power to the aircraft. Liu Chu said.

"Gear box?" Tong Zhenghai's eyes widened, the first generation of aircraft developed by Karakuri City were all driven by ink cores, and they had to be more than five stars to be able to activate them, and they could only provide half an hour's endurance.

Liu Chu's flying machine actually only needs a gear box? As soon as the operating lever is pulled, the gear will rotate thousands of times to provide power? In other words, this is artificial power!

Tong Zhenghai breathed a sigh of urgency, and when he looked at Liu Chu again, he seemed to have seen a treasure, and the appreciation and cherishment in his eyes were undisguised.

If Liu Chu's gear box is used with the ink core, wouldn't it be able to provide a longer battery life?

"If it weren't for the limited materials, I could have made it a machine that is in constant motion, but now it can only fly for an hour. Liu Chu said with a regretful face.

Tong Zhenghai was stunned, his heart was completely crazy, he could only fly for an hour? You must know that the first generation of flying machines that had been developed by Karakuri City for several years, and with the use of the Nine Rank Ink Core, it was only enough to fly for an hour!

If it weren't for the fact that Liu Chu hadn't come into contact with the original generation of aircraft in Karakuri City, Tong Zhenghai would have suspected that Liu Chu was satirizing the skilled craftsmen in Karakuri City when he said this.

"Second uncle, play with me for a while!" Tong Botao stared at the operating lever and wanted to play with it.

Tong Zhenghai nodded, will leave the operation position, and give the operating lever to Tong Botao to play, this thing is easy to operate anyway, Tong Botao can easily control it, even if it is tied to a piece of meat in front and a dog to drive, maybe it can be operated yo-yo.

Tong Zhenghai turned his back and looked at the vast land in the distance, the feeling in his heart was incomprehensible, he was thinking now, Liu Chu was such a genius, what else could he teach him?

With Liu Chu's talent, he can give him a drawing at will, and if there are materials, he can quickly make a finished product, and maybe he can improve it, draw inferences, and make more sophisticated ingenuity.

Tong Zhenghai covered his face, he seriously doubted that he was qualified to accept Liu Chu as an apprentice? If he did, I am afraid that there was only one item that he could teach him.

Tong Zhenghai took a deep breath and turned to look at Liu Chu: "Are you willing to worship me as a teacher?"

Liu Chu grinned: "Master is above, be worshiped by the apprentice!"
