Hacking involves information spying, psychological applications, and anti-reconnaissance techniques. Social engineering attacks often produce a variety of attack methods through the so-called human hardware vulnerabilities, that is, the limitations of the human brain's thinking, some of which include: pretending, phishing, online chat, baiting, equivalent exchange, tailgating, etc.

The success of an attack, regardless of whether the consequences are serious or not, is a big problem in the field of cybersecurity. In short, the person who can play this kind of tall and tall is a superhuman existence for people who can only reinstall the system with one click.

The essence of this work lies in the construction of a time and space outside the three-dimensional real world, where hackers from all over the world gather in a secret network, and hold hacker salons from time to time.

Compete with each other, or compete with each other, they all want to become the masterminds behind the real world who can play with the real world at will, and become a big man.

Among them, the villain MRX, in this salon is a god-like existence, all kinds of shrimp soldiers and crabs will take him as a benchmark, and he is also arrogant, but because there are loopholes in the three views, there are loopholes in the professional ethics of hackers, and there are loopholes in being a man, his road to self-inflicted sin and life is quietly rolled out, and the program of being cocooned is being written.

The protagonist always knows his extraordinary strength and just keeps a low profile. The team leader doesn't understand this, and wants to get a response from MRX wishfully, but in fact, he also asks MRX to admit their strength in disguise, and as a result, MRX's self-serving character is exposed, ridiculed, sarcastic, intimidated, and all kinds of bad things behind it.

Anyway, it was such a team that was squeezed into a laughing stock by MRX, and in the end, because the goddess of justice helped it open the way and became its protector. In the battle with MRX, Clay turned from passive to active, not only completely dismantling MRX's vulnerable mask, but also retreating from the trap set by MRX and becoming a real winner.

The screen scrolls there, the code swoops up and down, and the audience has no idea how mysterious the program is, but once it is combined with the visual picture, such as the street power supply system, it is paralyzed, and it is restored......

Another example is the printer convulsion of the entire intelligence department, the tampering of computer graphic information, and so on......

One operation is as fierce as a tiger!

I have to say that when technology and crime are combined, the requirements for imagination are not generally strict, thinking is not good, it is necessary to have a solid basis, it is a big bird that can go to the sky and the earth, in addition to this, there must be skills, and it needs to flutter out of the demonic spirit of the dragon without seeing the end.

But unlike Hollywood's hacker-themed crime genre films, this work has a slow pace, the character traits of the characters are down-to-earth, and the plot develops to a climax, and the conflict is still unstoppable.

The director's tribute to "Fight Club" is undisguised, and it is really not a simple imitation, and the multiple personalities have just become a gimmick that the protagonist can use.

In fact, the protagonist is fully qualified to suffer from schizophrenia", and the childhood trauma referred to by Freudian psychoanalysis has a deep imprint on the protagonist's consciousness and memory.

Even he himself does not deny that, like those psychopaths with multiple personalities, his upbringing environment is a lesion. The schizophrenic gene of the mother who committed suicide by drinking a bullet may also be present in the protagonist's body, and a broken family can easily shape a complex protagonist.

These hypotheses are theoretically based, and it is likely that the protagonist is a schizophrenic with hysterical identity disorder.

When the protagonist turns himself in, the four members of Clay's group become the four souls of the protagonist. The first image is ignorant, flamboyant, and weak, and he talks everywhere as if he can do anything; the second is a scoundrel, a sloppy, and brain-dead, like a crazy screaming follower; the third is cowardly, suspicious, and stupid, but his reckless appearance is wrapped in a coquettish heart; the fourth is inferior, autistic, and hopeless, but he has a good heart, knows how to think, and will blame himself.

The fourth personality tends to be the core personality and usually manifests itself as negative, silent. Non-core personalities are hostile, eccentric, violent, and antisocial personalities.

Imagine that these four souls are mixed together, if they are really divided and cannot be rescued, then the final result is tragedy, the "good" in the body cannot bear the "evil", and finally self-loathing and self-spurning, like "Fight Club" and "Black Swan", destroying themselves.

Multiple personalities are generally split into two, such as fight clubs. There are also splits into three, such as the three-faced Eve. "Fatal ID" is split into 11. Not to mention 24 billys.

It's just a set play-within-a-play, a game designed by the protagonist and his team in a specific situation, to kill two birds with one stone, to capture the real murderer MRX, and at the same time confuse the self-righteous secret police, then this is the protagonist who uses psychological knowledge to simulate the behavior of the elite.

In Ding Cheng's view, everything is to explore the problems that exist in real life, such as mental disorders and survival pressure. Even if there is a difference between multiple personality disorder and a schizophrenic, whether it is a body with multiple souls self-loathing and self-destruction, or a soul whose various behaviors seek the pleasure of destruction through external attribution.

In the digital age, the number of patients is increasing year by year, and the clinical experience of professional psychologists is also enriching, and the effect of intervention is becoming more and more obvious, such as the British female artist Kim Noble, after treatment, her personality has remained fixed at 12, and they are all positive, optimistic, and kind.

This movie uses hackers as a fashionable means of transportation to play the reversal effect of the eighteen bends of the mountain road, these tricks that can earn word of mouth, and they finally light up the theme of the movie: who am I, there is no absolutely safe system, and human beings themselves are the biggest loopholes.

Because man is not a god, he cannot avoid subjectivity and egoism, he can only see what he wants to see, and he is only willing to believe what he wants to believe. Such prejudices and limitations can easily lead to hell for the innocent in order to protect their own interests.

From the role of a female investigator, she has insight into the dilemma of social justice, because she represents power, and has the obligation to judge right and wrong, promote good and punish evil, and maintain justice, so the multifaceted nature of this character is a reflection of the complex social environment.

After the virtual world of the Internet becomes people's spiritual world, the stories that happen here can also be written into a dramatic story, even if it is full of loopholes and laughter, it can be used for entertainment and pastime, and it is most fun to write a suspense comedy that can be touched by the vine.

Various IDs of various websites, and there can be countless IDs under the ID of the same website, in short, a person's N identities and N images.

I try my best to play the other self, but I always unintentionally reveal my truest self, and that self will make the viewer stumble through the glasses and imagine the scene I depict.
