I'm really immortal

Chapter 705 Continuation Chapter 43 Age of Mythology
At present, the largest bird in the world is the African ostrich, and their weight can exceed three hundred catties, which is about the same as many fat houses.

The combat power of a fat house is generally equal to 0.5 geese, which means that two fat houses can be tied with a big goose, and an African ostrich of 70 kg can run at a speed of [-] kilometers per hour, and can trample one to death with one foot. Big geese, so when the weight is similar, if the fat house meets an African ostrich, you must not act rashly, and please be careful!
Although the African ostrich is big, it is nothing in Liu Changan's knowledge, not to mention that its feathers are also very short, so the down feather in Liu Changan's hand must have nothing to do with ostriches.

"Now the bird with the longest feathers in the world is the long-tailed chicken. Generally, its tail feathers can reach more than seven meters in length. 40 years ago, there was a long-tailed chicken whose tail feathers were as long as 13 meters. That is to say, if it stands at four feet Its tail feathers can be dragged to the ground downstairs." Liu Changan absorbed the knowledge about birds from his extensive knowledge and said to himself.

"I thought it was a peacock." Li Hongfang said embarrassingly, probably not only herself thought so, most people with little knowledge would think so.

Li Hongfang is not a bird researcher or a fan, but she is a lover and collector of Song paintings. She told Liu Changan about this when Liu Changan sent her to fetch "A Picture of Shanghe at Qingming Festival".

There are many Song paintings that Li Hongfang has appreciated. Song paintings of flowers and birds are the pinnacle. Li Hongfang has seen quite a few birds in them, but the birds in Song paintings are basically small birds, the biggest ones are eagles and peacocks, so peacocks are born. The impression of the longest tail feathers is also normal.

The long-tailed chicken is an artificial breed that has only been cultivated in the last two or three hundred years. Li Hongfang has never seen it in Song paintings, so he is naturally not familiar with it. Among the animal species that have not been eaten before, everyone has eaten chickens. Even if the tail is long, it is meaningless.

"Could it be the feathers of a red long-tailed chicken?" Li Hongfang followed Liu Changan's words.

"No. The tail feathers of the long-tailed chicken are long enough, but the body is not big. It has the down feathers the size of a normal folding fan. When this bird spreads its wings, it is probably bigger than a heavy fighter. Just imagine a J20 about the size Birds fell from the sky..."

"How big is the J20? I know it is the most powerful fourth-generation heavy fighter in the world." Li Hongfang nodded with a little understanding. Such a big bird must have been extinct, and only this feather in front of him is left.

"Beware of the engine warning." Liu Changan smiled, "It is more than 20 meters long and more than ten meters wide... The wingspan of this bird must be more than ten meters wide... That is bigger than a heavy fighter jet."

"How can there be such a big bird? I think it existed in the age of dinosaurs." Li Hongfang thought for a while, then shook his head, "There should not be any in the age of dinosaurs, and the largest flying dinosaur could not be so big. It is too big to fly... …maybe be able to use terrain to glide."

"It wasn't in the age of dinosaurs, but it was in the age of mythology." Liu Changan held the down feather and shone a flashlight on the down feather.

Feeling that the red light from the night vision glasses was too dazzling, Li Hongfang took off his eyes and stared directly at the down feather.

Li Hongfang can understand the age of dinosaurs, but what does the age of mythology mean?
Under the illumination of the flashlight, the down feather was bright red and dazzling, the color seemed to be flowing blood, faintly exuding a crystal luster, with the texture of jade and the vitality of blood.

Li Hongfang had never seen such a thing.

Liu Changan stretched out his hand and pressed the surface of the down feather, and the thin fluff undulated like seaweed in the water. The edges of the fluff curled up, gently wrapped Liu Changan's fingers, climbed to the fingertips and fell down again. Down, as if expressing intimacy.

"What does the Age of Mythology refer to?" Li Hongfang also wanted to touch this feather, but she was a little terrified. Ever since she experienced watching a part of her body decay and die, she still has psychological shadows. This mysterious and strange thing, the thin hairs reminded Li Hongfang of something that Shangguan Dandan pulled out of her body.

That time, Shangguan Dandan tied her arms with his arms, and each hair was pulled out from her flesh. On Shangguan Dandan's hair, there was a thin layer of blood film, which was that smooth. And the flexible feeling is very much like the down feathers in front of you (Chapter 428).

Now it seems that the first time I entered this tomb, I was probably marked by this piece of down feather... I can't say that it was a plot, after all, Li Hongfang doesn't know what effect it has on her. I don't know if Rasputin's method has anything to do with this down feather.

"There was an era when giant beasts could swallow clouds and fog and move mountains and seas." Liu Changan sighed, "Blue whales with a body length of tens of meters and a weight of two to three hundred tons were very common in that era. If a herbivore with a length of 40 meters and a weight of about [-] tons appeared in that era, it would probably be kept in captivity like a lamb and used as a source of food."

"There is still such an era? Then... how many years ago is that?" Li Hongfang was terrified after imagining it. If ordinary people heard it, they would only think that Liu Changan was telling fairy tales. Some special experiences, knowing that the mysteries of this world are beyond imagination.

The earth was born billions of years... The number of billions of years is too large to give people the feeling that it is just a number, but if someone can live for billions of years to experience it slowly, they will know how long it is. .

In such a long time, any era may have been born, and even some people can live for billions of years, and it is impossible to experience all the eras, maybe they will miss or forget...then modern people can only use technological means to understand Studying the past, studying the times that the earth has experienced, probably understands only a drop in the ocean.

"I don't know." Liu Changan shook his head, "Time is continuous and indivisible. The so-called unit of time, the records of the era, are all done by humans themselves. What happened in those times that were not recorded and discovered by humans Things cannot be positioned on the age scale of human invention."

"Human beings existed at that time, right? It's just that modern humans haven't found strong evidence of their existence in that era, so it seems that they never existed. It's just a myth?" Li Hongfang thought for a while and nodded understandingly, "Like the Xia Dynasty , Even many highly developed civilization relics before the Xia Dynasty have been unearthed, but the ancient history of our civilization is still not recognized by the Western historians.”

"That's right, I can't remember clearly, and I can't tell how many years ago... I have to call it the Age of Mythology, but this feather...maybe from that era." Liu Changan stared at the down feather, " If there are dragons, maybe there will still be an era of phoenixes."
-
That... I'm just reminding you in a very gentle and friendly tone, don't popularize knowledge about phoenix males and females, it's embarrassing to read too much.
