"Why is there such a difference?" The female translator asked puzzled.

"This one of mine is male, and Mr. Chen's one is female," Old Man Ouyang explained, looking at the two "monkey eagles". Listening to Old Man Ouyang's words, we suddenly realized, but after thinking about it carefully, this is also normal - no matter how special this bird is, it should also be divided into male and female.

At this time, Madman Six suddenly asked Mr. Chen with a mysterious face: "Does this bird of yours often spit something out of its mouth?" ”

Crazy Six's question surprised Mr. Chen: "Yes, how do you know?" It does spit something out of its mouth, it's slimy, it's white when it comes out, but after a while, it's going to turn gray, and it's going to get very hard, at first I thought it was sick, but then I realized it wasn't, it seemed like a normal reaction, it would be like this every once in a while, so then I got used to it. ”

The cousin suddenly asked Madman Six: "Did you see it from the meridians of this 'monkey eagle'?" ”

Madman Six nodded: "Yes, although the appearance of these two 'monkey eagles' is almost identical, their meridians are very different, I guess that this difference in meridians may be caused by different genders; And that kind of swift will spit out something on a regular basis, which is why I came to this conclusion. ”

"Is that kind of swift spitting out what we usually call 'bird's nest'?" The female translator took out a small notebook and asked questions while recording, because of her background in a biopharmaceutical company, she was always very interested in this kind of strange creatures.

After getting along for such a long time, the hostility between Crazy Six and the female translator slowly disappeared, so Crazy Six answered the female translator's question more calmly: "It's a little similar, but not exactly the same, the kind of 'bird's nest' we usually talk about is indeed a nest built by swifts with saliva, but the kind of swifts I am talking about, what they spit out of their mouths, is not used to build ordinary nests, but a kind of 'incubator'." ”

Hearing what Madman Six said, my cousin's brows stretched and his spirit was shocked, as if he had suddenly figured out something, while a few of us were still confused, not knowing what Madman Six said had to do with the 'skull stone' we were discussing.

Maniac Six then explained: "If you talk about it, it's also very wonderful. Generally, birds incubate eggs, all rely on the bird's own body temperature, and the swift I am talking about, the way of incubating eggs is very different - it will lay eggs first, and spit out white gelatinous matter, layer by layer to wrap the eggs, that white gelatinous matter, after encountering the air, will become hard and gray, forming a thick layer, and then the swift will wrap the eggs, exposed to the outside, exposed to the sun, after one or twenty days, the swift will secrete a liquid, dissolve this layer of hard shell, and then incubate with its own body temperature for a day or two, The swifts will be able to hatch from the eggs. ”

"Are you saying that the female 'monkey eagle' is similar to the way the female swift hatches eggs?" Xiao Lei asked a little surprised.

Maniac Six didn't speak, just nodded silently.

"According to what you said, the kind of stone wrapped around the egg of the 'monkey eagle' is actually formed by the substance that the mother 'monkey eagle' spits out of her mouth?" After listening to my cousin's conclusion, we suddenly realized and were shocked - we really didn't expect that kind of 'skull stone' was not a natural stone, but a secretion formed by the body of the "monkey eagle"! It's incredible.

However, if this is the case, then why there are eggs in the "stone" can be explained, and I can't imagine that the way the 'monkey eagle' even hatches eggs is so special.

It turns out that the madman six has gone around in such a big circle, and he is still talking about the origin of the "skull stone".

"Then why is there a skull-shaped particle in the substance spit out by the 'monkey eagle'?"

Regarding Hongmei's question, Crazy Six shook his head and said: "I don't know much about this, as for the particles in that substance, why it is in the shape of a skull, maybe as Kenya said, this is just a coincidence, but the substance spit out by the 'monkey eagle' and the air is formed after the reaction, according to the definition of physics, it is indeed a kind of crystal." ”

But for us, this skull stone is so mysterious that why do people temporarily lose their memories when they see the skull-shaped particles inside? How does this explain this from the sound of science?

In addition, since there are "monkey eagle" eggs here, there must be "monkey eagles" around.

But why did this "monkey eagle" and skull stone happen to appear in that crater, is it a coincidence? Or is there another reason?

At this time, my cousin suddenly said: "I probably seem to have figured out the escape method of Zhu Leting, the vassal king of the Ming Dynasty. When my cousin said this, everyone immediately became excited.

The escape of Zhu Leting, the vassal king of the Ming Dynasty, is indeed too mysterious and incredible for us, what kind of escape plan did his strategist Xuan Heng make for Zhu Leting?

I thought this mystery was unsolvable, but I didn't expect my cousin to have a clue, how could this not make me excited?

Under our eager questioning, my cousin still spoke slowly in his calm tone:

"Zhu Leting's strategist Xuan Heng, the background is very strange - although he himself is a fallen man, but his family has been raising birds for generations, but it is difficult for you to understand, raising birds can become a profession, in fact, in the Ming Dynasty, our area, raising birds is indeed a profession, this kind of birds raised by bird keepers, generally divided into two categories - one is used for hunting, such as eagles, eagles, etc., many hunters will buy this kind of birds of prey for hunting; The other is ornamental birds, such as parrots, starlings, larks, etc., with special sounds or bright colors.

Xuan Heng's family is engaged in this kind of occupation, but their family has a much richer income compared with ordinary bird keepers, as for why this is so, I will talk about it later.

It is also the ancestors who do this business, so Xuan Heng has been very familiar with all kinds of birds since he was a child, and even knows how to breed new varieties, but Xuan Heng's father feels that he has raised birds for several lifetimes, except for a little money, it is not promising, the so-called 'everything is inferior, only reading is high', so he sent his son to study, and wanted to take the exam for an official and a half-job in the future.

But Xuanheng's road to the imperial examination was very unsmooth, and after he was admitted to the examination, he repeatedly failed to succeed, however, he was shrewd and capable, and by chance, he was introduced to Zhu Leting's Mansion and became a guest, but what he didn't expect was that Zhu Leting loved birds like his life, and Xuanheng was born in a 'bird-raising family', and he was extremely familiar with various bird habits, so the two had a common language, and Xuanheng gradually became Zhu Leting's henchman.

Zhu Leting's escape to this crater should have been planned by Xuan Heng a long time ago, and among the people who fled with Zhu Leting, there was Xuan Heng, and they all disappeared mysteriously in this crater.

I thought about it again and again, and felt that it was precisely because of this background that Xuan Heng might know about the bird 'Monkey Eagle', and his understanding of this bird may be beyond our imagination.

I also heard Mr. Chen say that this 'monkey eagle' was once the 'patron saint' of an Egyptian pharaoh, and for Zhu Leting, the 'strange bird' he was holding when he fled can also be regarded as his patron saint, and it is almost certain that he can get into the cave of the crater, and that bird plays a key role, and that bird should be the 'monkey eagle'.

When we were in the crater, I also mentioned that it was recorded in the history books that after Zhu Leting and several people entered the crater, there were several screams from the pit, and that kind of scream was not like a human being, it should be the bird in his arms, according to my speculation, that kind of cry was made by using the special frequency in the mountain to open the entrance to the cave.

Moreover, when we were in the pit, we also let Brother Ouyang's 'monkey eagle' call on the spot, and after calling, a hole really appeared, and from that hole, Mr. Chen's 'monkey eagle', who had been missing for a long time, also came out.

I think that our 'monkey eagle' may be called in the wrong place or in the wrong way, and the hole is not open enough, but this is enough to show that the cry of the 'monkey eagle' can indeed open the dark hole in the crater.

The escape method used by Xuan Heng seems incredible, but it is actually a hidden mystery.

If in this crater, the dark hole is built by artificial methods, it is simply impossible, because we all know that the stones in the crater are too hard, with the construction technology level of the Ming Dynasty, it is impossible to carry out it at all - not to mention that in that crater, even if the cave is built in other places in the mountains, it is a huge project, and there is no such manpower and material resources in our area. Confidentiality cannot be guaranteed at all.

Therefore, as far as the construction of caves is concerned, the prehistoric human beings are really too clever, not only much more clever than the Ming Dynasty, but even compared with the current construction technology, it is not even inferior.

Why am I saying this?

I just want to explain a point - the hole in the crater was definitely not built by Zhu Leting and Xuan Heng, but the cave originally existed, maybe it was natural, or it was built by prehistoric people, but it was just discovered by Xuan Heng.

How did Xuan Heng find that hole? He was not a geologist, and the history books did not say that he knew feng shui, so based on his knowledge of bird habits, as well as his practice of using bird calls to open the entrance of the cave, it can be roughly inferred that the hole under the crater must still be a guò bird.

According to this line of thought, I suddenly remembered a record about Zhu Leting -- I have too many historical materials in my head, maybe I am old, so many historical materials are not immediately remembered -- what kind of record is that?

It's a strange thing about Xuan Heng.

Starting from Xuan Heng's grandfather, people found that their family could raise many strange birds, and these birds, not to mention other bird keepers, no one had even seen them in nature.

For example, their domestic eagles, not only slightly larger than the average eagle, the appearance is also very different from the average eagle, and very smart, can quickly understand people's various commands, domestication is very easy, when used for hunting, it is more handy, the prey captured, many times higher than the average eagle, and this kind of eagle, can also help the owner pick the bird's nest on the cliff, Ganoderma lucidum, etc., therefore, the eagle of the Xuanheng family, the price is more than ten times more expensive than the average eagle, but it is still in short supply, relying on this advantage, the Xuan family soon became a local rich family, and the average bird keeper, in terms of income, is simply not comparable to it.

People feel that the Xuan family must have an ancestral secret method of raising birds, for this secret method, the Xuan family is strictly confidential, absolutely "inside not outside, men not women", and so on to Xuan Heng's generation, Xuan Heng only discovered this 'secret method of raising birds' shocking secrets. ”
