Because of the material structure and other reasons, the flapping wing structure is the most common, if not the only, flight mode of living organisms.

Regardless of the angle of attack, chord, comprehensive aerodynamics, heading, and variable wingspan, only according to the simplest and rough frequency of the flapping wing, and briefly dividing the three kinds of high-frequency, medium-frequency and low-frequency, the larger birds, as well as the pterosaur, etc., the relative proportion of the wingspan and the area of the wing are the largest, but the frequency of the flapping wing is the lowest, the activity mode of the wing is relatively simple, and the interaction with the air and airflow is relatively lowest.

Fly in flapping + glide flight mode.

And the smaller and medium-sized flying creatures will have a smaller wingspan and a lower flapping frequency, and the proportion of gliding in the flight will be smaller.

As for the small size, from small creatures such as swallows, sparrows, and even dragonflies, the ratio of wingspan to body is already the smallest, and the frequency is relatively fastest, and the proportion of gliding is also the smallest, and the interaction with air and air flow begins to become complicated.

Of course, after reaching a certain limit, the proportion of gliding rises -

Because the weight has dropped to the point where you can blow them up with just the air current.

Compared with the other three wyverns, the Lepidopterasaurus has the smallest wingspan, the highest fluttering frequency, and the highest interaction with air and airflow, which needs to be adjusted many times.

Moreover.......

Lepidoptera's back muscles don't seem to be strong enough to support this high-frequency flutter.

He had let the Lepidoptera fly twice, and the third time, it couldn't fly.

When I looked at the amount of blood, I lost two points of blood.

“.......？”

Because it's too heavy?

Di Xing glanced at the label and couldn't help but glare.

Flying so hurt, is it hard to add a restorative label to Lepidoptera?

The effect of body weight on the ability to fly, and the effect on the frequency of fluttering, is the most significant.

More precisely, the impact on the "material" is the greatest.

The higher the speed and the higher the fluttering frequency, the greater the strength of the material required.

Like an ordinary fixed-wing aircraft, if it becomes an ornitary-wing aircraft of the same size, the demand for material strength will increase a lot.

For overweight, large creatures, try not to consider high-frequency flapping.

The dragonfly's flight mode is indeed not very good-

To think about it, you can only think about big wings like butterflies.

Or.......

Transformable wings?

Isn't there an elf in this world? In the fantasy world, don't elves often have fantasy professions like "druids"?

The strange deer he hunted before seems to have a deformation-related label?

If you can really get the fantasy means of transformation, you don't necessarily have to have the ability to fly in a regular state, and you don't need to integrate the flying ability into your own body, taking into account various characteristics.

You only need to make a [general] form, and this general form can be transformed into a form suitable for various environments?

However, this is just a backup solution.

Composite form is still the first choice.

After thinking for a moment, he walked inside the colony, ready to upgrade all the tags for himself.

At the same time, he plans to give the Anti-Raven, Odd Wyvern, and Lepidopteran Evolution [Dragon's Blood] tags to enhance their control and commands.

Also, start building a new core, ready to try it out and let them be used as scouts to scout the environment near the swamp.

.......

A few days later.

Above the swampy sky, the bone-eroding mist of the death attribute had disappeared, and a pitch-black creature with a bird's beak and feathers flapped its wings, clawed a crystal clear red-shelled monster egg, and flew into the sky, flying at an altitude of about a hundred meters above the ground.

"I can't use vision, and sure enough, I should raise the core of reconnaissance to lv2? A perception radius of at least 200 meters can ensure the safety of the Scout Wyvern? ”

"No, those elves I saw before, the range of bows and arrows should be more than two hundred meters....... It's not safe enough. ”

In the crypt area, a blood-red monster with a body size of more than four meters and nearly five meters was lying on the ground.

A long, stout, powerful tail, sticking out from behind it, was swaying slightly, clutching a stone with sharp corners, carving on the ground the general topography and landmarks of the swampy area.

And his claws, on the chest and abdomen, pad his body.

Seriously, he thinks tails are better than claws.

However, at this time, a dark shadow stepped on the ground on the map he had just drawn.

The end of the tail, the strange limbs like claws, opened and closed not far in front of him, the West Wind Abyss Dragon, who was cleaning up the rubble on the ground of the stronghold, and put it on the other side near the rock and soil wall.

The West Wind Abyss Dragon was grabbed and put down, but there was no panic in the movement, looking left and right, a pair of hard and powerful pliers pierced the gap in the rock and soil wall, pried the clods of earth and gravel off, and then picked up the rubble and transported it to the corner.

It's doing its job of digging.

Not far away, the Yar Marsh Dragon and the small shield dragon were also using their tail paws and forelimbs and mouth to clean and carry the surrounding rubble and clods.

And in the face of the current size of the earth, the black-scaled bird-faced dragon with a body size of less than one meter is also obediently doing the carrying work.

The Black-scaled Bird-Faced Dragon and the Zephyristic Dragon are currently part of the Underground Guard.

The Yar Marsh Dragon, the Little Shield Dragon, and the Earth Walk also used the black-scaled kobold as materials, giving them the [Underground Environment Adaptation] tag that can be observed in the dark.

The Bird Dragon, no, it should be said, the Bird Dragon, transferred to the organization, was incorporated into the air force, and at this time it was sheltering on some tall trees outside the crypt, foraging for food, and at the same time, it was responsible for vigilance, and when it found danger, it made a cry or came back to report.

Lepidopterals and Odd Pterodactyls were responsible for the rest of the directions.

At present, the anti-crow, which has the strongest flight ability, is tasked with flying with an extended core and taking a bird's-eye view of the swamp environment.

After fully confirming the swamp environment, he prepared to have the air force slowly move out of the swamp with the extended core, drawing a map while searching for resources.

The food resources of the swamp are no longer enough.

Now that he is about to reach five meters in size, there is no meat left to eat.

However, just as the anti-crow was flying in the northwest direction of the swamp with the expansion core, suddenly, through the expansion core, it saw the anti-crow turn around sharply and let out a low cry.

Not a hoarse crow, but a rough and low roar.

Immediately, he remotely instructed the anti-crow to place the extension core at the top of the tree.

After a few minutes, he finally saw a few figures, and saw the target that the anticrow had noticed—

Genie.
