"Perhaps, these forest whites can absorb nutrients and grow branches, and at night, they can sense the presence of living rao when they exhale miasma, so as to shake the leaves and branches to attract these flying insects, and then when the flying insects are finished hunting, maybe they inadvertently help them complete pollination, or give them some nutrients that they can't normally get through the soil."

Song Siyuan's eyes lit up here: "Animals and plants in nature generally do not have the kind of communication through sound that humans have, but there must be a unique way of communication, so that they can coexist or help each other in the forest, and such a relationship not only exists between plants, but also among animals." ”

For example, crocodiles' teeth are relatively large, and after hunting and biting raw meat, there is no way to completely clean up the debris of minced meat, and if the minced meat is allowed to block the gaps between the teeth, it will cause crocodile teeth to decay, eventually causing tooth loss, and even parasitic parasites.

In the case that they are unable to clean their teeth, this much-needed function is replaced by another species in nature - the swallow thousand birds.

Near the crocodile habitat, there is a kind of swallow thousand birds, also called toothpick birds, whenever the crocodile bites the prey, lying on the tidal flat to rest, it will deliberately open its mouth, let the nearby toothpick bird come to his mouth to feed, this toothpick bird reminds very much, can directly help the crocodile clean the gap between the teeth, while satisfying the foraging, it is also equivalent to emptying the crocodile's mouth.

For example, the rhinoceros has many wrinkles, and some parasites like to parasitize in these skin folds to suck blood and parasitize, but the rhinoceros body is extremely bulky, and he can't clean up the parasites in the skin folds, so the rhinoceros bird plays a role.

These rhino birds are extremely flexible and can dig their beaks deep into the folds of their skin to dig out parasites, so that the rhinos can ensure that there are no parasites in the skin and the rhino bird can eat well.

Everyone listened to the case introduced by Song Siyuan, and finally understood what his communication meant, and Xu Xiake suddenly realized: "Oh, what you mean is that these plants in the forest may not know the purpose of the flying insects, but as long as they attract the flying insects, they can get the substances they want, so as to reach a tacit understanding with the flying insects and cooperate with each other in a symbiotic relationship." ”

"Well, that's kind of what it means."

She paused and accentuated her tone: "Let's go back to flying insects, if such insects are placed outside, it may be a rare spectacle, but in Shennongjia, it may just be a normal situation, I remember Tan Yanqiu and Sun Daqiao have been with us, a kind of snake in Shennongjia." ”

In the past, Tan Yanqiu and Sun Daqiao mentioned that when they were digging tombs decades ago, they had an immortal snake.

These undead snakes are of different colors and sizes, ranging from long snakes with thick wrists to snakes with fingers half a meter thick, with dark red and black patterns on their bodies, which look like fiery red and black cockscomb snakes to outsiders.

Their peculiarity is not that they are brightly colored, but that they can never be killed with a sword, even if these snake bodies are broken into several pieces, they can continue to writhe, and even without breathing, they can already see the broken bodies bite into each other, and finally close the wound, and then turn back into a full snake body that is alive and bouncing.

Song Siyuan mentioned this immortal snake, most people still have an impression, she saw that everyone had already remembered the situation, and continued: "Before, I have always been curious, what kind of creature has been cut into several pieces, not only can it not die but also return to its original state, such a state violates the laws of nature, and has even reached the point of weirdness. ”

"I've always been curious about this, and it wasn't until I saw a bug like this that I understood what the hell was all about."

Song Siyuan mentioned this, and her eyes flashed: "These undead snakes are likely to be in the same way as flying insects, scattered insects gather to be long snakes, and they have to form a group gathering form because they are too easy to encounter enemies, so they can be used to avoid enemies and facilitate hunting." ”

"Since they are a bunch of insects, of course, there is no way to kill them, as long as they perceive danger, they will automatically disperse to avoid danger, when the sword is added, in fact, the swarm is cut off, and when the sword disappears, they are out of the dangerous illusion and will be regrouped."

"Whether it is a flying insect or an undead snake, the gathering of groups is because of the strange environment of Shennongjia, which is the only way for organisms to adapt to the environment."

Song Siyuan's words, everyone believed it, Yue Guanchao asked: "Then, the matter of this Yin soldier is completely caused by these insects?" But the problem is that the records of the Yin soldiers not only appear in Shennongjia, but also in Xiangyang. ”

His question does exist, if the Yin soldiers in Shennongjia are caused by flying insects, then what is the matter with the Yin soldiers in Xiangyang?

Song Siyuan thought about this, clasped her lips and hissed and explained: "Idealism is too subjective, what we think of as the Yin soldiers asking for their lives is actually just flying insects foraging for food. Could it be that their descriptions are completely objective descriptions that are faithful to the facts, and perhaps, mixed with subjective judgments? ”

After she finished this, she looked at everyone with obscure eyes: "Back then, the premise of these warlocks coming to Xiangyang was that there was a Yin soldier crossing in Xiangyang, and the government sent a warlock to investigate the existing Yin soldier crossing, and the final result had to indicate to the nearby people that these dead souls were actually the fallen soldiers of the Beifu Army, which was strange enough." ”

Song Siyuan took out the Xiangyang Fangzhi she found: "Later, Liu Yu has already determined that he will choose Shennongjia to build the Beifu Yiguan Tomb, and at the same time make a vow to be buried in the Yiguan Tomb after death, when these records are from the hands of a literati who talks about metaphysics, it proves that this article is not an objective description, back then, Liu Yiqing did not also use this to boost morale for Liu Yu's Northern Expedition." ”

"You know what I said!"

Song Siyuan decided to break through the fog: "Serving the Northern Expedition in the name of ghosts and gods, this is just another show, in essence, it is no different from the Han Gaozu Liu Bang beheading the white snake, I had this idea at that time, the Yin soldier incident may be fake, it's just that they borrowed the Yin soldier phenomenon of Shennongjia and forcibly associated it with the two, anyway, it is the Yin soldier crossing, and no one really dares to verify it." ”

She paused, and set the tone: "Whether it is the Xiangyang Yin Soldiers, or the Shennongjia Yin Soldiers, they are just interpretations of the phenomenon of the Yin soldiers, not the truth of the Yin soldiers. ”

"Good girl, I suddenly remembered a kind of worm, which is a bit similar to this flying insect."

Yue Qingshan didn't wait for everyone to ask, and said bluntly: "Bugs, this kind of bug is very similar to what we see, but the body is gray-brown with white spots, it will also release poisonous gas, in the eyes of the old man, the bugs in the outside world are just ordinary bugs, the bugs here can not only glow, but also have a human face on their backs, probably it's yours, it is the environment that has prompted genetic changes, so that these bugs have become such a state." ”

This also means that these craftsmen were lost in their souls by the so-called Yin soldiers, but in fact they were only confused by insects, and the craftsmen could not hear any words, and it was also because of the confusion toxins emitted by a large number of bugs, so that their brains had been paralyzed.

Xu Xiake questioned again: "Then, these flying insects can imitate people, so what?" They create the illusion of Yin soldiers, they are always conscious, right? These bugs form human forms and human figures, so what? ”

This is really hard to explain, flying insects can imitate human portraits in clusters, and it is clear that flying insects are definitely consciously communicating with each other, this is not a tacit symbiosis with plants, and the insect colony must know what it is doing.

Song Siyuan said: "Probably, because insects have some ability to extract memories, I suspect that all the portraits they imitate are living people they have preyed on, as long as the living people are consumed by them, then, about the memories of living people, they will also be absorbed, as more and more living people are preyed, they can also pretend to be more living people, in order to confuse living creatures, or drive away dangerous opponents." ”

"This kind of trick is very good in nature, I remember that I have used to have some insects in order to survive, they often disguise themselves as snakes, as for things like dead leaf butterflies and stick insects, they have made the camouflage simulacrum to the extreme, in essence, it is the best choice made by creatures in the face of survival."

She paused and said in a heavier tone: "The situation in Shennongjia is different from the norm, and the creatures here are of course different from the norm, but the deer here can fuse plant genes, and it is estimated that no creature can escape the distortion of genes." ”

Speaking of this, she continued: "There are so many things, the environment of Shennongjia may distort the genes of all animals and plants, so it is not surprising that a large number of albino animals appear, and even the ghost side may be the product of genetic distortion. ”

At this point in the discussion, everyone has broken the illusion of the Yin soldiers, knowing the details, and understanding that the so-called Yin soldiers crossing the border is just a trick of insects and plants.

A night of vigilance and light sleep, until the moon ring disappeared and the green reappeared, these yin soldiers dispersed and gradually disappeared without a trace.

Yue Guanchao removed the nails and opened the porch, walked along the corridor to the vicinity of the Que Tower, and carefully observed the leaves on the trunks of the nearby trees, there was really a lot of slime left on them, as if they had greased the leaves.

These things are probably what the human face bug left behind, and probably, this is the "reward" that the human face bug gives to the trees, in exchange for the cooperation of the trees.
