"It is said that in the pre-Qin era, there was a mountain of Zheshan, which had many water flows in the mountains and no flowers and trees. There is a big waterhole in the depths of this mountain abyss, and there is a kind of fish in the waterhole, shaped like a long snake, and there are six pairs of wings as thin as cicada wings on its back, and any living creature is entangled in it, and it dies immediately, and it is called a demon shark, which hiberns in winter and revives in summer. The demon man is invisible, and people can only see it when they smear their eyes with the tears of the plough ox. ”

Listening to Wang Lei's introduction, Xiao Ling felt that the long snake-like white light and shadow that had just been killed by the grenade was very likely to be the demon shark recorded by the ancient secretary of the Qin Dynasty.

The only thing that is different is the wings behind it, there are six pairs of wings as thin as cicada wings behind the foreign body demon shark recorded in the ancient books of the pre-Qin Dynasty, whether the long snake-like white light and shadow has wings at that time, Xiao Ling is not sure, now that he thinks about it carefully, it seems that there are indeed wings in the faint light and shadow, but because it is so thin that it is almost transparent, it is difficult to find if you don't look carefully.

Thinking of this, Xiao Ling nodded and said: "In this way, this should be the demon shark mentioned in the ancient book, I can't imagine that there is such a foreign object in the world, and the human eye can't see it." ”

Yu Tingting said: "Most people say that they can see some things in the underworld after smearing the tears of the cow, is this demon shark also something that does not belong to the underworld that should exist in this world?" Xiao Ling, your eyes look different from ours, only you can see. ”

Xiao Ling is a little impressive, in fact, since the car accident and his brain was damaged, he can see some strange things from time to time, he can see the miserable white hands that do not exist in the world, and now he can see this demon shark that is invisible to ordinary people.

Xiao Ling understands that there is an essential difference between this demon shark and the miserable white hand, the demon shark is just invisible to ordinary people, but it is real, although it can't be seen, it can be touched, and it can kill people, just because of some incomprehensible reason, in the eyes of ordinary people, it is like invisible.

According to Xiao Ling's current view, it seems that it cannot directly act on the real world, and no one or matter in the real world can touch it, it seems to be an illusory existence, but it has a certain mysterious power, but it seems to be real.

After that, everyone talked about Wang Weiguo.

Although Xiao Ling decided that the killed Wang Weiguo was a monster, and the appearance of the monster changed into Wang Weiguo's appearance, what he couldn't understand was how this monster knew something that only Wang Weiguo would know.

Xiao Ling expressed his doubts, and Zhou Kesheng groaned: "The immortal tree collapsed, Wang Weiguo fell down like us, maybe he encountered this monster in the process, this monster occupied his body at that time, and even plundered his memory, disguised as him, and then mixed into us and took the opportunity to kill." ”

Xiao Ling said awe-inspiringly: "Is there really such a terrifying monster in this world? As he spoke, he looked at Wang Lei.

Wang Lei was so knowledgeable about all kinds of animals and beasts that he even recognized the demon shark, if there was really some kind of monster in this world that occupied people's bodies and memories like this, he would definitely recognize it.

Wang Lei thought for a moment before he said: "There are many records in the ancient books of the pre-Qin Dynasty that there are some similar strange beasts and strange things, including the zombie Gu in our previous period, this kind of Gu worm can make people look like zombies and be controlled by them. In fact, in addition to zombie Gu, there are also a variety of parasites that have similar abilities that can control the host, such as an ancient fungus parasitic in the body of ants, which can change and control the behavior of ants by releasing chemicals, making them become their own puppets, until the ants finally die, these zombie ants are like walking dead, only a shell remains. ”

Another example is the double disc fluke, a parasite that can control the brain of a snail, similar to zombie ants, and is called a zombie snail. Specifically, it refers to the amber snail parasitized by the parasite of the genus Collarius fluke, this parasite can enter the digestive system of the snail and grow into a long tube, which is filled with hundreds of cercariae with reproductive ability, this long pipe invades the tentacles of the snail, forming a weird, swollen and pulsing appearance, in order to attract the attention of birds, when birds eat this snail, it will become the host of the second stage of this parasite, and the eggs are excreted on the plant through the bird's feces, and then parasitize on other snails, Continue to begin their life cycle. ”

Xiao Ling listened to Wang Lei's introduction, and goosebumps rose all over his body.

"So, Professor Wang's strange behavior may have been parasitized by some kind of parasite?"

Wang Lei shook his head, as if he didn't know how to explain Wang Weiguo's situation to Xiao Ling, and paused before continuing: "Recently, a tyrant leech was discovered in the Peruvian Amazon River Basin, they are the king of leeches in the jungle, it can be said that it is the nightmare of all explorers, and its name is still above the piranha. The name of this tyrant leech is the same as the Tyrannosaurus rex in English, it is a veritable king of leeches, once the tyrant leech bites a person, it will burrow under the skin of the person, all the way into the brain, and will continue to lay more eggs in the human body, up to hundreds of thousands, these eggs will hatch from the human body in a very short period of time, eroding all the organs of the human body, and will release a variety of chemicals, until the control of people's thinking, as one, the person parasitized by the tyrant leech no longer belongs to himself, Until the human body is completely emptied by these tyrant leeches and turned into an empty shell, such a person may suddenly fall off his head when he walks, and there will not be a drop of blood flowing from his body, only countless holes like beehives, in which hundreds or thousands of leeches will crawl. ”

Other people were also attracted by these weird and terrifying parasites that Wang Lei said, and they were a little creepy when they heard him say that they were terrifying.

"Oh my God, there are these horrible leeches in the world." One of the team members couldn't help but be shocked.

Wang Lei nodded and said: "The world is so big that there are no wonders, and nature has given birth to almost endless kinds of strange creatures, and the creatures we know now are only afraid that they are not even one percent. Professor Wang Weiguo's sudden abnormal behavior has no reasonable explanation for the time being, but I think it cannot be ruled out that his mind is controlled by some kind of parasite, which may have been a legendary monster in ancient times. ”

He paused for a moment and continued: "Of course, there are not many parasites that occupy and control people's bodies and minds that have been discovered now, but those that can seize people's memories have not been discovered for the time being, but there are still too few creatures that we can recognize, and if such monsters really exist in this world, it is not known." ”

Xiao Ling couldn't help but sigh when he saw that Wang Lei had been talking for a long time, and finally failed to make a reasonable explanation for Wang Weiguo's inhuman changes.
