At present, the largest bird in the world is the African ostrich. Their weight can exceed three hundred kilograms, which is similar to many fat houses.
The combat effectiveness of a fat house is generally equal to 0.5 geese, which means that two fat houses can beat a big goose, and a three-hundred-pound African ostrich can run at a speed of 70 kilometers per hour and can be trampled to death with one kick.
It's a big goose, so if you encounter an African ostrich, you must not act rashly and be careful if you encounter an African ostrich of similar weight!
Although the African ostrich is large, it is nothing in Liu Changan's experience, not to mention its feathers are very short, so the down feathers in Liu Changan's hands 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. Forty years ago, there was a long-tailed chicken with a tail feather that was 13 meters long. That is to say, if it stood
On the fourth floor, its tail feathers can be dragged to the ground downstairs." Liu Changan said to himself, absorbing his extensive knowledge about birds.
"I thought it was a peacock." Li Hongfang said embarrassedly. It was probably not just him who thought so, but most people with little knowledge would think so.
Li Hongfang is not a bird researcher or lover, but she is a hobby and collector of Song Dynasty paintings. She told Liu Changan about this when Liu Changan sent her to pick up "Along the River During the Qingming Festival".
Li Hongfang has appreciated many Song paintings. Flowers and birds in Song paintings are the pinnacle. Li Hongfang has seen quite a lot of birds in them. However, the birds in Song paintings are basically small birds. The biggest ones are eagles and peacocks, so peacocks are born.
The impression that the tail feathers are the longest is also normal.
Long-tailed chickens are an artificial breed that was developed in the last two to three hundred years. Li Hongfang has never seen them in Song Dynasty paintings, so naturally he is not familiar with them. Even if he saw them in the zoo, he would not be impressed. Everyone usually goes to the zoo.
Looking at the types of animals that have not been eaten before, everyone has eaten chicken. Even if the tail is long, it is not interesting.
"Could this be the feathers of a red long-tailed chicken?" Li Hongfang said following Liu Changan's words.
"No. The tail feathers of the long-tailed chicken are long enough, but the body is not big. It has down feathers the size of a normal folding fan. When this bird spreads its wings, it is probably bigger than a heavy fighter jet. Just imagine a bird about the same size as a J20
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 some understanding. Such a big bird must have become extinct, and only the hair in front of him is left.
"Be careful of the engine warning." Liu Changan smiled, "It is more than twenty meters long and more than ten meters wide... The wingspan of this bird must be more than ten meters wide... That means it is larger than a heavy fighter jet."
"How can there be such a big bird? There must have been in the dinosaur era." Li Hongfang thought for a moment and shook his head, "There probably wasn't in the dinosaur era. The largest flying dinosaur couldn't be that big. It was too big to fly...
…maybe able to use the terrain to glide.”
"It didn't exist in the age of dinosaurs, but it existed in the age of mythology." Liu Changan held the down feathers and shone a flashlight on the down feathers.
Feeling that the night vision glasses made the red light too dazzling, Li Hongfang took off his eyes and stared directly at the down feathers.
Li Hongfang can understand the Age of Dinosaurs, but what does the Age of Mythology mean?
Under the illumination of the flashlight, the down feathers were bright red and dazzling, the color seemed like flowing blood, faintly exuding a crystal luster, with the texture of jade and the vitality of blood.
Li Hongfang has never seen such a thing.
Liu Changan stretched out his hand and pressed the surface of the down feathers. The thin down feathers undulated like seaweed in the water. The edges of the down feathers rolled up and gently wrapped around Liu Changan's fingers. They climbed to the fingertips and then fell down.
Come down, as if expressing intimate emotions.
"What does the Age of Mythology mean?" Li Hongfang also wanted to touch this feather, but she was a little scared. Ever since she experienced watching a part of her body decay and die, she still has psychological shadows.
This mysterious and strange thing, with its tiny hairs, reminded Li Hongfang of what Shangguan Dandan had pulled out of her body.
That time Shangguan Dandan tied her arms with his arms and pulled out her hair one by one. There was a thin layer of blood film on the tips of Shangguan Dandan's hair, which was so 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 she entered this tomb, she was probably marked by this downy feather... It can't be said that it was a plot. After all, it had any impact on her. Li Hongfang still doesn't know what the withered and depressed state of her body is.
I don't know if Rasputin's methods have anything to do with this feather.
"There was an era of giant beasts that could swallow clouds, spit out mist, and move mountains and seas." Liu Changan sighed, "Blue whales that were tens of meters long and weighed two to three hundred tons were very common in that era. Three species of Argentinian dinosaurs
If a forty-meter-long, one-hundred-ton herbivore had appeared in that era, it would probably have been raised in captivity like a lamb and used as a source of food."
"Is there still such an era? Then... how many years ago was that?" Li Hongfang was horrified after imagining it. If an ordinary person heard it, they would just think that Liu Changan was telling a fairy tale, but Li Hongfang had it after all.
Through some special experiences, I learned that the world has many mysteries that are unimaginable.
How many billions of years have the earth been born? The number of billions of years is too huge and feels like it is just a number. But if someone can live for billions of years and slowly experience it, they will know how long it is.
.
In such a long time, any era may have been born. Even if some people can live for billions of years, it is impossible to experience all eras. They may miss it or forget it... Then modern people can only use technological means to understand all eras.
If you study the past and the eras that the earth has experienced, what you probably understand is just a drop in the ocean.
"I don't know." Liu Changan shook his head, "Time is continuous and indivisible. The so-called units of time and records of times are all things humans do. What happened in those times that have not been recorded and discovered by humans.
Things cannot be positioned on the age scale of human invention."
"There were already humans at that time, but modern humans have not found strong evidence of their existence at that time, so it seems that they never existed and are just regarded as myths?" Li Hongfang thought for a while and nodded with some understanding, "Just like the Xia Dynasty
, even many highly developed civilization relics before the Xia Dynasty have been excavated, but the antiquity of our civilization is still not recognized by Western historical circles."
"That's right, I can't remember exactly, and I can't tell how many years ago it was... I can only call it the Age of Mythology, but this feather... maybe it comes from that era." Liu Changan stared at the down feather, "
There may still be an era of phoenixes if there are dragons.”——
Well...I just reminded you in a very gentle and friendly tone, don't try to popularize knowledge about phoenix male and female, it will be embarrassing if you read too much.
