The moment he fell, Chen Yan was a little frightened in his heart.

She believes that it is likely that the intruder wanted to kill her in a hallucination. Maybe the other party has read her brain information, and her brain is useless and has been disposed of.

It's all too easy to kill a person in a fantasy, like creating an earthquake and suddenly a cliff appears. People who are hallucinating are usually killed in astonishment before they have time to react to whether or not it is plausible to appear now.

People who die in hallucinations are also brain dead in reality. But thankfully, she didn't fall to her death. The ensuing lights made her realize that this was still a haunted house for the playground.

This time the light is an ordinary dim light, like the most honest kind of tungsten light bulb, which consumes electricity, but is cheap and durable.

The sudden light caused her to reflexively close her eyes, only to tentatively open a slit in her eyelids after a moment. Lance said anxiously on the side: "Chen Yan, are you okay?

Chen Yan shook his head. They were now covered with a large elastic cushion under their feet, and she could even feel the bouncing on it as she fell, and though she couldn't see it clearly, she could feel that the mat was thick.

"What about you?" she asked, "are you alright?"

"Of course it's fine. Lance said, and seemed to stand up. His physical fitness is many times stronger than Chen Yan's, and it is normal for him to adapt quickly.

Chen Yan stayed for a while before slowly opening his eyes, scanning the surrounding environment, and was immediately stunned. Here, it is almost a copy of the ancient tomb that her father took her to when she was a child, almost identical.

Seeing that she was still stunned, Lance stretched out his hand to her with concern. Chen Yan looked at the hand in front of him and silently pulled it to get up. She looked around and saw that the place where she had just fallen was an entrance, and there was a rope ladder down from below, and if she wanted to go up, she could climb the rope ladder directly back to the surface, which was a place that resembled a basement, and was arranged to resemble an ancient tomb.

Unlike the ancient tomb she remembers, there is a toilet in one corner of the space...... Probably for the convenience of tourists, there is actually one in such a hidden place. Originally, there were very few people walking this road, so it was very clean, even the old-fashioned sink outside the toilet was white, and such a modern facility really didn't match the overall atmosphere of the space.

Lance was not very satisfied with this, he said: "When you go out of the haunted house, you must go to the opinion book and write this item, there is no warning, it is easy to cause tourists to be injured." ”

Chen Yan nodded and spun around here. At first sight, she was a little excited, but after two turns, she was not in that mood at all.

The ancient tomb that her father took her to was perennially filled with the smell of earth, and there was an inexplicable sense of heaviness in the air. Every time he went, little Chen Yan couldn't help but be solemn. In the face of such a thick sense of history, I can't help but be serious, and I am always ridiculed by my father, and I become a little adult as soon as I enter.

And here it is completely imitated, the main coffin of the golden silk nanmu is made of unknown synthetic materials, the copper tripod in the corner looks light and fluttering, and even some of the funerary goods seem to be cheap glass beads.

It's really not interesting. But then again, it would be strange if there were genuine golden silk nanmu coffins, thousand-pound copper tripods, and real gold, silver, jewelry, and night pearls here. It seems that the person who created the hallucination was also very careful.

Chen Yan suddenly felt that it was difficult for him to get out in such a careful intruder hallucination. At that moment, a hint of despair welled up in my heart.

She shook her head, suppressing the thought to the bottom of her mind. Baimi is still a mistake, and besides, this intruder is an illusion created from her memories, so it is impossible not to miss the slightest omission.

Then she set her sights on the toilet in the corner. It's not about discovering something – it's about addressing physiological needs. I didn't expect the hallucinations here to be so real, even she remembered eating and drinking too much water at noon.

So Chen Yan said hello and went to the women's toilet. When I washed my hands, I looked at the mirror on the table and sighed long, I still need to work hard.

But...... Since you can't find flaws in the people and scenes around you, it's better to think about starting from other angles. While he was thinking, Lance's worried voice came from outside, "Chen Yan, are you okay?"

Although everything here was an illusion, Chen Yan was still moved by Lance, who was suddenly so warm, she raised her head and replied loudly, "It's okay, wait for me, it will be fine soon." ”

Lance outside answered. Chen Yan continued to think about the sink. This sink is old-fashioned, with a faucet above and a concave basin-shaped container made of white ceramic below, with a hole in the center that permeates water downward.

She looked down and thought for a while, and out of the corner of her eye, she saw the permeable hole, and her heart moved. A theory about the optic nerve of the brain comes to mind - visual blind spots.

The formation of blind spots is the organism of a certain link in the evolutionary process,

The optic nerve produced by the human eye is distributed in the front end of the retina, and in the course of human evolution, human descendants can only tinker with this foundation and will not make major changes to it, so that it is now like this. In the beginning, the optic nerve was the product of an evolutionary process called the blind spot. It is said that the squid's eyes did not have blind spots, because their ancestors evolved in such a way that the optic nerve was distributed behind the retina.

In the early years, one of the arguments that creationism refuted evolution was that the eye must have been created by God and could not have been created by evolution.

However, what is the reason why the human optic nerve division is at the front end of the retina is no longer verifiable, anyway, when medical evolution has discovered this, it is impossible to change the position of the optic nerve.

Visual blind spot, simply put: when a person sees with two eyes, the same point of reflected light reaches the retina of the left and right eyes in different positions, even if one light is exactly in the blind spot, the other light will not be in the blind spot of the other eye, so we see the complete image. A blind spot is the point on the retina where there are no visual sensory cells.

The way to find a blind spot is to see things with only one eye, and if you are careful, you can see. Covering one eye, such as the left eye, and then using the right eye to look at one of the two targets in different positions, you can make the red of the two colored dots, one red and one blue, move the head back and forth to change the distance between the eye and the target, and when you reach a certain distance, you will find that the other blue dot disappears.

Everyone has a blind spot, it's just that the distance of the blind spot is different. The first time Chen Yan discovered that she had a blind spot was when she was very young. One night, on a whim while washing, she stared at the sink drain with her spare eyes, only to find that when she got up the thing, the drain hole was missing, and the bottom of the sink was sealed!

Frightened, she immediately bent down to take a closer look, and found that the sewer hole had reappeared. Then she touched it with her hand to make sure the drain hole was there. But when she got up, the drain hole was no longer visible! she could still touch the hole without seeing the drain hole.

So the young Chen Yan was not so materialistic that he was frightened into the bed, and he didn't dare to come out all night.

Later, I found out that it was because of blind spots.

But now that she is hallucinating, what she sees is not real, but the illusion created in her brain by the intruder, so will the blind spot not appear?

She thought about it and decided that she should give it a try. Then she covered her left eye and looked at the spot on the sink, her eyes looking at the drain hole, slowly moving her head back and forth to change the distance.

No matter how far you go, the drain hole is always visible with your right eye, which means there are no blind spots!

As soon as this thought jumped out, Chen Yan felt that his eyes were dark, as if he had entered a vacuum of lightless and silent space. But it didn't last long before she heard someone talking in her ear.

There are many unfamiliar sounds, so noisy that they make people feel irritated, mixed with a kind of "zi-la-la" sound that is disturbed by the transmission of radio waves, and occasionally some vague sounds that seem to come through something.

Chen Yan found that she seemed to have come to the underground of the Red Brigade where Sam, the intruder she killed, was located in a trance. Because the style and equipment of the room look like it is unique to the Red Brigades.

She seemed to have headphones in her ear, and from it came a conversation that seemed to be on a string:

"After so many years, when will the signal stop?" someone seems to be complaining.

"Who knows. There are enough monsters on Earth now, won't we all go up in the future?" the other man's tone was not very good.

"Well, I don't know what Master Seth thinks, so I have to send those signals...... "Seth? Isn't he the leader of the Red Brigades?" Chen Yan felt that this conversation was probably someone who had invaded her brain, and was bored to eavesdrop on other channels when she was in the Red Brigade.

"How can we guess what adults think, let us do whatever we want. The other said, and then, as if unwilling, muttered, "That is, my lord, you can know what signal to use to lure the giant beast to Earth." But it seems to have attracted a little too much......"

Hearing this, Chen Yan was shocked. In an instant, many puzzles were solved: why the earth has existed in the universe for tens of millions of years, but only now has a giant beast come, and why the giant beast has come one after another, even though it has nothing to eat.
