Chris thought to himself: that log stake is called "death", and what Brother Teng said is indeed right, as long as you hit it with a mallet, the sound it makes can open the mechanism. Pen & Fun & Pavilion www.biquge.info

It's just that when she was on the island before, she couldn't have imagined that the "blank sound" was the key "key".

At this moment, when the blank sound was also gone, and all that was left was the sound of the passing wind, the circular floor of the "Boom la ......" rumbled loudly.

There was a jolt under Chris's feet. She remembered that if she forced her way into the Dragon Formation, spiked stakes would pop out under the floor, but if she struck the right "Death Sound", she would be able to open the Dragon Formation smoothly.

Circles of concentric planks spread outward, and as they unfolded, a deep well appeared in front of them.

This is efficiency, Mo Dai ordered the children of the Mo family to build a "Dragon Array" as quickly as possible, and the location was in a clearing in front of the observation tower.

The Dragon Formation was indeed hollow, and there was something hidden underneath, and she already had seven or eight guesses in her heart. But the mood was still excited before the mystery was about to be revealed, and Chris couldn't hold it anymore, walked to the edge of the wooden well, and looked down.

At this time, the floor of the bottom layer of the wooden well began to rise slowly.

The contents were revealed: a large wooden object, resting quietly on a base with bronze gears, that looked like an eerie postmodernist-style wood carving.

Chris frowned, it was so strange! It didn't look like the trap kite he imagined, there was no other way to describe it, and most importantly, it didn't look like a bird at all!

Seeing her reaction, Murdai pursed her lips and smiled.

When the pedestal rose to ground level, the noise finally stopped.

The torso of the wooden statue is tightly condensed together, like a folding umbrella, and the only thing that can be seen is the shape of the tail. Chris noticed this detail and immediately walked towards the position of the tail.

Chris studied industrial design, which is an eye-opener even from her professional perspective. It is a very complex tail system: twin vertical tails and flat tail shapes, with huge twin vertical tails arranged at both ends of the flat tail. The front half of the vertical tail is fixed, which is probably the same as the "vertical stabilizer" in the tail of modern aircraft, and the "rudder" of the second half is hinged to the rear of the stabilizer, which can be slightly deflected to control the direction of flight. The large area of the vertical tail, especially the pair of rudders, should greatly improve the stability when sailing at the angle of attack.

Chris thought to himself: the double vertical tail style is probably to improve the efficiency of the flat tail.

The flat tail is divided into two parts, each with four adjustment tabs, which are symmetrical to each other, like a bird's tail. The front half of the wing surface is also fixed, and the "elevator" in the rear half is attached to this "horizontal stabilizer", which should be able to deflect up and down to control the climbing and descent of the flying kite.

Chris marveled at the intricacy of the structure, and when she looked closely, she saw that the hinged vertical tail and flat-tail parts turned out to be blue metal.

Looking down at the base, the two sets of gears and bearings are also this cool-toned metal. Suddenly, she noticed that there was a lever with a copper handle.

What does this lever do?

She immediately turned her head, just about to ask a question.

Who knew that Mo Dai had already made a gesture, pointed to the lever, and said, "Please!"

Chris swallowed and foamed, his hands tightly gripping the huge copper-handled lever and pulling it down hard.

With a "bang", I saw that the parts that were condensed together at the front end were slowly lifted upwards, and then expanded to the sides. The wooden wings were inlaid with a dark blue metal skeleton, which glittered in the morning light, and a large bird seemed to be guided by the blue light, spreading its wings.

"Wow!" she exclaimed in disbelief, "So that's the whole picture of the Wood Kite!!"

The head of the wooden kite is a pointed bird's head, and the body is a cylinder, which resembles a shuttle with only one pointed head, and the middle part of the cylinder is hollow, and there are two wooden chairs inlaid inside, which seems to be suitable for two people. The huge wings are so cleverly designed that they can be retracted, so when not in use, they need less space when folded, and the structure is easy to disassemble, install and transport.

The wings of modern aircraft are made up of skin and endoskeleton, and the structure is generally streamlined. The flying kite in front of me also has a wooden inner skeleton and skin, but a blue metal outer skeleton is embedded in the wooden skeleton.

This metal exoskeleton, also known as the "spar", has two sets of circular "articulation hinges" on top of it, which allow the wings to make a movement similar to that of a bird flapping its wings. Each "articular hinge" extends into three blue metal ribs, and near the inside of the kite's body, a pair of wooden reinforced ribs are attached to the metal ribs, which Chris guesses are mainly used to maintain the shape of the wing profile and allow the skin to spread.

Chris noticed that the shape of the flying kite's wings resembled the wings of a bat more than the wings of a bird. She touched the thin wings, but she didn't expect them to look thin, but the texture was very strong. In this way, the skin is both tough and malleable, and I don't know what material it is made of, and the surface seems to be coated with a layer of gum, which should play a role in protecting against rain, so that the wooden kite can fly like it in the rain.

Chris was most concerned about the blue metal skeleton on the wings, and the connecting parts on the tail wings, which looked like they were mixed with blue secret stones. She turned around and asked Mo Dai, "Is there something blue like Scorpion Island added to this skeleton?"

As she expected, Mo Dai gave an affirmative answer. When building the ink village on Scorpion Island, the disciples of the Mo family discovered the blue secret stone. Murdai spent a long time studying this strange ore, and she discovered that the powder of the secret stone could burn when exposed to fire, and emitted a very bright light. Later, it was discovered that the rats in the passage were extremely active and frighteningly strong, and several adult men could only work together to deal with a single mouse. After setting a trap to catch one, Murdai noticed that the blue stone was stained with a rat that could eat without stopping. The Mo family's mechanism has always used small animals to drive the core of the mechanism, and she tried to put the blue mouse into the mechanism, and the mechanism could run for several days in a row, which gave Chris the "flying on the grass".

It wasn't until dozens of Mo family disciples were injured by a group of ferocious and brutal blue scorpions that Mo Dai discovered that they had come out of the depths of the earth, and a few reckless disciples ran to drive these scorpions away, but they were stung to death by poisonous scorpions. Scorpions are growing in number and size, making them difficult to deal with. She wanted to continue her research on the Blue Stone, but she was plagued by scorpions. Eventually, Mo Dai decided to evacuate the valley and abandon the repaired Mo Village.

Murdale pulled a piece of paper out of her pocket and handed it over.

After Chris read it, although there were many names that she didn't know what they meant, she almost immediately understood that this was the recipe for making the metal of the wing skeleton! This recipe was very complicated, many metals had different boiling points, and she didn't know how Murdai used to smelt them together. Coupled with such a mysterious substance as the Blue Secret Stone, how many failures it would take to successfully make an alloy, Chris can fully imagine the hardships.

Sighing heavily, Mo Dai said, "It's a pity that this recipe is useless!"

"Useless?" asked Chris.

"The wing bones of this flying kite were made by an old blacksmith of our Mo family. He forgot to sleep and eat, and when he finally succeeded in building it, he also fell ill, and this recipe was left to me before he died. Later, we built it according to this formula, but no matter how much we tried, we couldn't smelt it successfully. ”

Chris suddenly remembered the black kryptonite that was as active as a creature, and thought to himself: Maybe the blue secret stone also has a similar unstable property, and the inside of the crystal will constantly change, so he said: "This may be a one-time formula, if you want to smelt it again, I'm afraid you need to try a new formula." ”

"That's what I thought, too. Murdey said with some frustration, "It's a pity...... It's really rare to see a capable person like the old blacksmith!"

Chris thought to himself, an organization like the Mo family that gathers construction wizards has unsolvable problems, and it seems that the work of finding talents is really urgent. But first, you need to be able to dig up the blue stone.

She pointed to the sky and said, "Can you show me?"

Mo Dai nodded and waved her hand slightly.

Two Mo disciples walked over from the side, and they placed a pair of ladders on the side of the flying kite.

Following the ladder, Murdale climbed up first and sat in the front seat, while Chris followed closely behind.

Murdale skillfully operated. On her right-hand side is a set of brass-handled levers

When they were all seated, the dozen or so Mo family disciples on the circular platform quickly withdrew and stood a little farther away.

Over Murdale's shoulder, Chris looked ahead, where the complexities of the instrument clusters, monitors, and control panels found in modern aircraft cockpits are not mandatory, but the most basic set of joysticks are indispensable to control the wings and tail, to control direction, take-off and landing.

Mo Dai pushed the first lever as if the engine had been activated, and Chris could feel the flying kite beneath him vibrate and hum. Thinking of the blue liquid device powered by the "rat force", she guessed in her mind what such a huge trap Feiluan was powered by.

Next, Murdey spun a bronze turntable on an operating table.

The gears and hinges of the base began to move, and Chris noticed that the wooden kite began to slowly turn to one side, and at the same time rose upward, turning straight one hundred and eighty degrees, and the position of the base was also raised by two or three meters.

At this point, Murdai pushed the second lever.

As Mo Dai's hand slowly pushed the lever forward, the four "joint hinges" on the metal spar flattened the entire wing, and began to lift up from both sides, the pair of huge wings lifted up, and then fell downward, a few times later, the flapping wings became faster and faster, and the wind whirred. This reminded Chris of a helicopter. The high-speed spinning propellers kept making loud noises, and without the headset, people couldn't possibly stay in the cabin for that long, and she couldn't help but worry.

While Chris was still pondering, he only heard a "click", as if something had loosened, the wooden kite's body shook, and the huge lift pressed Chris tightly on the chair, and the wooden kite suddenly rose into the air.

Each flap of its wings made the wooden kite rise a lot, and it slowly surpassed the lookout platform on the hill.

In mid-air, a flock of birds flew by, visibly frightened, and let out a high-pitched call, perhaps warning their companions of the approaching predators.

The wings finally stopped fluttering, like the wings of a modern airplane, stretched flat on either side of the flying kite's body. The kite keeps climbing, and it flies higher and higher, higher and higher, to be precise. There is no wind whistling of wings flapping during takeoff, and no noise from those "rat power engines".

Chris was amazed, and kept repeating the moment he had just taken off in his mind.

In Chris's memory, from the age of steam to jets, to modern aircraft designed on the basis of a series of theories such as bionics, rigid body mechanics, fluid mechanics, structural mechanics and vibration theory, it is still difficult to compare with the masterpieces of nature. Bird flight skills have long been considered lighter and more efficient than fixed wings, so in the era of 2025, flapping wing system aircraft that simulate bird flight are the domain of research for many aerodynamicists. The Mo family's wooden kite uses a flapping wing system, which not only simplifies the structure of the fuselage, but also reduces the overall weight. Instead of the thrust provided by the propeller and jet engine, it creates an upward lift during the flutter, and when the swing speed is fast enough, it can take off.

Chris suddenly felt that something was wrong. She remembered the golden diamond-shaped secret stone floating in the air in the Cross City.

She leaned close to Mo Dai's ear and asked softly, "Senior Mo, this flying kite, like the little wooden kite I saw in the Cross City, also uses the golden secret stone given by the 'Immortal Lord'?"

Mo Dai smiled and didn't say anything, just nodded slightly.

She was amazed in her heart: The power used by this wooden kite is indeed not only the propulsion of the blue secret stone, but also the floating power of the golden secret stone. This is a wonderful design that surpasses the future! During takeoff, the flying kite has excellent vertical take-off and landing ability with the addition of blue stone propulsion and thrust on the flapping wing, and after level flight, it is changed back to a fixed wing, and the flight is more stable. Using the buoyancy of the Golden Secret Stone makes it too easy for the flying kite to hover in the air, which undoubtedly cleverly solves the problem of the aircraft's endurance.

Chris didn't continue to speak. As the kite had flown forward into a low cloud, the city spread out before her eyes, and there was silence all around. (To be continued.) )
