Hearing his son's comfort, Zhang Guangyao couldn't help but smile with relief, and his spirits were cheered up unknowingly, "You kid will brag about yourself. This is comforting me, and it is still a praising yourself."

Zhang Chujiu smiled and said, "Dad, what you said just now is so lively, but what exactly is 'mental pollution'."

Zhang Guangyao relied on his real skills to gain a foothold in a first-class university in China. He was naturally knowledgeable and talented, and his knowledge was not limited to his own professional field. After hearing this, he thought about it and replied: "The concept of spiritual pollution is difficult to describe, but it can be explained with examples."

Do you know the most original movie playback principle?"

Not understanding how 'mental pollution' can be related to movie broadcasting, Zhang Chujiu nodded in confusion and said, "I understand, we have learned common sense classes in the first grade.

The human brain has lags in memory of images, so if you play 24 frames of related images per second, it will produce a coherent effect from the audience's perspective, and it feels like the characters are alive. Therefore, the original movie was also called '24 frame art'."

"I remember the knowledge points in common sense classes very clearly, good, good." After listening to his son's explanation, Zhang Guangyao said with satisfaction: "Since you know the principles of the movie, it's easy to understand 'spiritual pollution'.

24-frame correlation pictures can form a movie in 1 second. What will happen if an unrelated picture is inserted into these 24-frame pictures and continuously playback within 1 second?

The human eyes will not detect abnormalities, but the subconscious mind of the brain will leave a mark.

Decades ago, Blue Star's most famous beverage company, Coyi Coke, once secretly conducted an experiment. Every 30 seconds of playing the movie, insert a picture or photo with the words "You want to drink Coke" or Coke. As a result, after the movie ended, about 80% of the audience went to grab Coke.

They are affected by 'mental pollution'."

Zhang Chujiu was slightly stunned and said in a daze: "It turns out that 'mental pollution' is like this, it doesn't sound very scary."

"Not scary, hum," Zhang Guangyao said in a deep voice after hearing this: "You are still a junior high school student, and it's too simple to look at the problem.

"Mental pollution" can make people sell coke unknowingly, and can also make people feel unexplained and commit suicide.

A long time ago, there were many "dark images and music" that would make people want to commit suicide after listening to it. The principle is to mix pictures like "You want to die, you want to die" in various languages ​​in videos, or to mix vague languages ​​like "You want to die, you want to die" in audio to make psychological hints.

People with weak mental health will feel negative emotions in a few minutes when they see and hear this. If they continue to watch and listen, it is not surprising that they commit suicide.

So now governments have long legislated bans, and any form of 'spiritual pollution' can't be used for advertising."

"So amazing!" Zhang Chujiu said in surprise.

Zhang Guangyao said expressionlessly: "Stop talking about humans, scientists have experimented with it. Even a docile pet dog often looks at pictures of similar biting and fighting, and they will become irritable and aggressive.

And such means are just the initial "spiritual pollution".

According to the novel, humans, like Crusoe, will be seriously 'spiritually polluted' and produce all kinds of negative emotions when they see their images and hear their voices.

Going crazy and self-harm are all light, and it is possible to convert directly into a monster."

"Mental pollution makes people crazy, I can understand self-harm, but it's too exaggerated to make people turn into monsters." Zhang Chujiu curled his lips when he heard this.

Zhang Guangyao shook his head and said solemnly: "On the ninth day of the lunar month, the impact of human spirit on the body is far beyond your imagination.

On the shallowest level, when a person is in a happy mood, his immunity will increase; when he is depressed, his immunity will decrease.

To be deeper, some scientists have done experiments and hypnotized that he was being burned by fire after hypnotizing him. The experimenter actually had blisters like being burned by fire for no reason.

In a deeper way, there is an experimental surface, covering the death row prisoner's eyes, fixing his hands and feet, and then slashing hard with an ice skate on his wrist, then playing the sound of water droplets falling.

Tell the death row prisoner that the blood vessels on his wrist had been cut and that the blood was constantly flowing out and dripping to the ground.

But in fact, there was no wound on the wrist of the death prisoner, but a few hours later, he really lost his life, and the cause of death was completely consistent with the characteristics of death caused by blood loss.

From this, it is not impossible for humans to undergo physical genetic changes under the influence of the mutated spirit after being "spiritually polluted" by the evil god.

As a scientist, I am reluctant to say this, but as a father, I must warn you: If you want to follow the path of professional religious people, then never underestimate the power of gods."

Zhang Chujiu trembled all over when he heard this, his face turned smooth, and he nodded vigorously and said, "I understand, dad."

"Just know, go to bed." Zhang Guangyao stretched his eyebrows and said with a smile.

Zhang Chujiu nodded, hesitated for a moment, and said with a pretentious concern: "By the way, dad.

Since you have become the person in charge of the research on marine life in Crusoe, you will definitely be exposed to many physical objects or materials with the nature of "spiritual pollution". Are there any precautions?"

"Of course there is." Zhang Guangyao thought his son was concerned about his safety and hurriedly comforted him: "We will not directly contact the subjects of physical research, and even look at them through special spectral glasses.

There is not much possibility of contamination.”

"That's the case, can I open my eyes?" Zhang Chujiu's eyes lit up, and he said with a curious look: "After hearing so much, I am also very interested in the Cthulhu myth.

If it is proven to exist in the future and becomes a separate sub-discipline under ‘religious education’, maybe I might not be able to apply for this major.”

Zhang Guangyao frowned and refused flatly, "How can this work? The experiment is not an amusement park.

Scientific research, especially this kind of scientific research that is dangerous and related to the field of evil gods, is not a game.

How can you, a junior high school student, get involved? You have watched too many science fiction movies, go to bed quickly.”
