Most of the pictures shown by Xue Bufan are corpses. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoThere is even a complete "fresh" skeleton that seems to have been carefully dissected.

Chenfeng has learned anatomy quite well, and has passed the first grade. He could naturally tell what kind of bones were fresh.

The bone pictures in the archives are simply fresh skeletons that cannot be produced by natural decay.

A sagittal ridge on the top of the head, along with four nearly identical limbs, indicates the skeleton's identity.

This made Chen Feng have to suspect Xue Bufan's means to get this skeleton.

"The Wu people who died of natural causes. According to custom, the corpses of the Wu must be eaten clean by a special carnivorous insect. ”

Xue Bufan unhurriedly took out another illusion. It was a wriggling swarm. Countless eight-legged arthropods that look a bit like foot armor. These bugs are about a finger long, but their mouthparts are so small that they don't match their size. The insect is dark in color, black, with a metallic sheen and golden veins.

As for the reference for Chen Feng to judge the size of the worm, it is the two small bulges in the worm pile.

It was the corpse of the Wu tribe.

"This is the funeral of the Wu people, and it is said that it is still the kind of size that is not small. Xue Bufan nodded to this picture: "They advocate 'circulation', and have a kind of obsession with 'dust to dust to dust', believing that allowing the corpse to rot is a desecration of the corpse and a waste, so the fresh corpse must be used as a feeding worm." ”

Chen Feng suddenly felt a wave of nausea. He pointed to the "alien beetle" that was gnawing at the corpse, covered his mouth, and said, "I remember...... They have this bug in their dipping sauce......"

"That's another bug from the same family. Xue Bufan deliberately delayed a second or two before taking out another picture: "Carnivores used to dispose of kitchen waste and spoiled insects, they don't breed much." For them, this should be the ...... A high-end ingredient similar to dog meat?"

Chen Feng took a closer look. The second type of insect that Xue Bufan took out was very similar to the first one, but there was no golden pattern, and the color was also grayish-brown. His face turned pale: "This kind of thing should be explained from the beginning......"

"I'm sorry, I'm sorry, it's the first time I've talked to someone, and I don't have much experience. Xue Bufan smiled heartily and said: "These two kinds of carnivorous insects are actually two species of the same genus, and the time for evolution to diverge should not be too long. Among these two types of bugs, there is even a phenomenon of reproductive isolation of 'post-mating isolation'. ”

"Post-reproductive isolation" is a type of "reproductive isolation", which means that "two species can mate and give birth to offspring, but the offspring produced is infertile". The most famous example of this is the mule created by the cross between a donkey and a horse.

Since reproductive isolation exists, that is, these two are certainly not one species of organisms. However, they are very similar in terms of diet or something else.

"Incidentally, the hybrid between this sacred worm, which is used exclusively for funerals, and this meat worm that disposes of food waste, is a terrible predator...... At least in their specs. Xue Bufan took out the third picture. It is still an "alien step beetle", but this kind of insect is a little longer and thinner than the previous two, and its mouthparts are larger than the "holy worm" used for funerals, and smaller than the "meat worm" that solves kitchen waste, which is just the size suitable for "predation". It inherited the carnivorous nature of the holy worm, its weak spiritual power [the monks of the Wu tribe also gave it to this insect for funeral], and the huge appetite of the meat worm.

Xue Bufan introduced that since this kind of insect cannot reproduce, the Wu people are very relieved to release them to catch all the pests they don't need in the dense forest and maintain the ecology of this dense forest.

"No wonder there weren't any bugs along the way. Chen Feng thought for a while: "I originally thought it was because we were the Shenzhou Terrans, and they didn't like the smell on our bodies. And when I ate the bugs, I realized that something was wrong. The fact that the worms are delicious in our mouths means that we are able to absorb the amino acids of the animals here, and vice versa......"

"You don't realize it, it's not a forest, it's a town and a pasture. Xue Bufan said: "The Wu people rely on grazing insects to obtain the essence of living beings. The pests are basically gone. ”

"However, knowing that the infertile insects are let out, it seems that the Wu people have a certain understanding of the way of balancing heaven and man, and the ecosystem......" Chen Feng muttered.

"Don't look at people who are poor now, but maybe they are too wide. Xue Bufan said: "The heritage of 200 million years...... How much can happen?"

"I always feel that there is something wrong, but I can't say what is wrong......" Chen Feng looked at the illusions suspiciously, and finally shook his head.

- Maybe it's a custom?

- If it's Wang Qi, maybe you can see something, right?

After knowing the origin of the bones, Chen Feng no longer had any doubts about those skeletons. Xue Bufan simply swept away all the illusions in front of him, and then made a gesture. Once again, the calculator creates a large illusion.

"Phantom Qiang's true rank, this skeleton can be moved according to your gestures. Xue Bufan said with a smile: "The new concept, my friend of the Tuowan Method, with this thinking, I feel that the thinking is not quite the same." ”

Chen Feng stared at the skeleton in front of him, almost forgetting to breathe, where could he care about talking about anything else? He was shocked: "This is ......"

"This is the skeleton of the Wu people. Xue Bufan waved his hand, and the virtual skeleton spread out: "I swept in a fresh Wu skeleton with the help of the big leader, and then I found ...... They don't have a spine at all. ”

The Chordates are not creatures of the phylum Chordates.

Directly below their skulls are four sets of bones. These four sets of bones form the cavity of the Wu people. Their digestive organs are in this cavity. Each of these four sets of bones extends into a limb.

It's completely different from what the Terrans imagined. There is no difference between upper and lower limbs. Their four limbs are simply symmetrical along the center of the head - of course, this is the beginning. After a long evolution, their heads have come closer to one of the set of limbs.

In other words, if the ancestors of the Wu tribe left the trees, they looked like four-legged spiders with human heads.

"They are more like cephalopods than like us mammalian humans. Xue Bufan manipulated the illusion, took off the head, and then dismantled it: "For example, this." It shouldn't even be called a 'skull', it's a shell ......"

Cephalopods, a class of the phylum Mollusca, are all marine, carnivorous, and although they are mollusks, most of them have no shell. In contrast, cephalopod organisms have a mantle cavity formed by a layer of musculature, tentacles, a well-developed head, and a pair of developed eyes on either side.

The representative creatures are the octopus and the squid.

Cephalopod creatures are considered to be the culmination of mollusk evolution. Because they have an endoskeleton that protects the well-developed brain. It is said that the dragons had the idea of bringing cephalopods to form a new civilization a long time ago, but this idea was abandoned due to the evolution of the human race.

Chen Feng quickly shook his head: "One thing is not quite right...... Cephalopod organisms, why do they have such complex ...... Skeleton?"

Cephalopods are characterized by a simple endoskeleton, but the parts that form the body, as well as the limbs, should not have bones.

"I'm not saying that the Wu are cephalopods, but I'm saying that the Wu are closer to the cephalopods than the mammals. Xue Bufan said: "And it can only be said that it is 'close', and they may not even be 'animals' in the narrow sense." ”

Chenfeng dotted the picture: "I understand...... Go ahead. ”

The premise of thinking should include "the Wu people are close to the cephalopods".

"The most important thing is to tell you, then the rest is nothing. Xue Bufan said: "In vitro fertilization of the Wu nationality, there is no concept of 'lactation', and neither female nor male has external genitalia. There is not much difference between the strength of females and males – be careful not to treat their females differently from males, or even to emphasize the distinction between females and males, as this may cause unhappiness. ”

Chen Feng nodded.

"Then, this is the ......" Xue Bufan removed the skeleton and replaced it with another image. It was the face of the Wu clan: "In order to use the tools, the eyes of the Wu clan are focused on one side. This gives them a very good stereoscopic vision, but their field of vision is narrower than that of humans. One hundred and thirty degrees to the left and right, and about forty degrees to the top and bottom. In response, his four noses have a separate sense of smell and can sniff out the direction the smell is coming from. Their hearing is also very three-dimensional. ”

"This is also the choice of the arboreal race. The branches and foliage of the Tianwu trees are lush, occluding the field of vision, so the binocular vision of the Wu people is relatively narrow. However, leaves cannot block the transmission of sound and smell, so hearing and smell take the place of vision. ”

Seeing that Chen Feng listened carefully, Xue Bufan nodded, and finally said, "Next, let's talk about the culture of the Wu people." ”

"You should have noticed that too. They have two kinds of self-names, one is 'Lulaling', a three-syllable word that has no deeper meaning. The other is the 'knot', and they have a special kind of worship for the knot. ”

"I don't know which deviation it is, but the Wu people have retained the custom of knotting ropes. They didn't invent papermaking, they didn't have writing – or rather, knots were their words. ”

"Perhaps because of their narrow field of vision, the strong sense of three-dimensional space of the arboreal race, and the characteristics of those seven fingers, they played the 'knot' tricks. There are some knots that are so distinctive that many people can read the meaning from the 'knots' – just like our words. ”

"In the same way, just as writing is divided into ordinary characters that mortals can use and magic seals with magical effects, the knots of the Wu people are also divided into ordinary knots and complex knots with magical effects......" (To be continued.) )
