The so-called reverse engineering refers to reverse engineering, a term commonly used in engineering technology. In software development technology, reverse technology refers to the degeneration of programming information based on a certain software, so as to crack it. A master of reverse engineering can roughly deduce how the software was written just by looking at it.

However, from the original two-dimensional computer software to the current virtual reality system, the difficulty of reversing is getting bigger and bigger. Fang Chi also studied computers, although he thinks his qualifications are mediocre, but he is also an expert. The so-called expert looks at the doorway, and she can still see the doorway.

Just by trying it once, you can reverse the ice cracking, if Xie Weishi is not bragging, then he is a hidden god whose level is comparable to that of Guest.

There is no one who does not know the most amazing thing about Guest is the ability to crack that has never been missed.

No matter what system it is, as long as it is in the hands of Guest, there is no possibility that it will not be cracked, it is just a matter of time.

In the world's top hacker contest Pwn2Own, compared with the more defensive T.N.T, and the whimsical Creeper, the Dagger Thrower is generally stronger than the attacking Guest, who undoubtedly played the most crucial role.

It's just that when Xie Wei, who was born in medical school and didn't study computer technology seriously, can he have a strong reverse sense (feeling, intuition) like Guest?

"You're not a guest, are you?" Fang Chi quipped.

"Do you think so?" Xie Weishi still looked like Mount Tai collapsed in front of him and his face did not change, just like he had not come out just now, but he had to hold it alone.

"Guest has been reduced to being a crow...... Fang Chi smiled self-deprecatingly, "It's quite open." ”

Not to mention going to places like the Cyber Security Bureau and Maandala, which are at the top of the pyramid, just go to an ordinary Internet company, and the guests are enough to eat and wear for a lifetime. Fang Chi remembered that Xie Weishi still borrowed a hundred yuan from Ding Feifei last night, and then looked at his ordinary clothes, and felt that he was poor, I am afraid that he was really poor.

"Guests can't be crows?" Xie Weishi operated the computer and said sullenly. When he watched the ice crack just now, the content of the ice crack had been transcribed to his computer, and as Fang Chi had built, it was reduced from a three-dimensional video to a two-dimensional video that could be watched on the computer.

"Really a guest?" Fang Chi pretended to be very surprised, and took a blank notebook over, "Sign it for me." ”

"No kidding." Xie Weishi smiled and pushed the book away. He clicked on the two-dimensional video of the ice crack, greatly reduced the playback speed, and pointed it out to Fang Chi frame by frame.

It was a post-apocalyptic picture of huge ice cracks, seismic waves, infrared images of volcanic eruptions, lava rushing and burning out.

Just looking at it as a static image can make you feel nervous, scared, and hopeless. Fang suddenly remembered the signature of the ruler between the eyebrows when it first appeared:

[The earth fire runs underground, rushing; Once the lava erupts, it will burn up all the weeds and trees, so that it is incorruptible. 】

In these pictures, there are a large number of fractal geometric patterns, chaotic, gorgeous, and mysterious, as if people are immersed in the depth and infinity of the universe.

Fang Chi has never seen fractal geometry in virtual reality, but fractal geometry must be more real and wonderful in three-dimensional virtual reality! The endless whirlpool that seemed to be deep to the end of time and space made Fang Chi almost have the urge to put on virtual reality glasses and go deep into the ice crack to explore.

"At the beginning, the images of nature and mathematics with a strong visual impact and a sense of spiritual mystery are used to disintegrate people's psychological defenses. I'm guessing the soundstage has a similar setup. ”

He called up the spectrogram of the sound field, and at the beginning of the 20Hz position, a small local peak suddenly appeared.

"Infrasound." Fang Chi blurted out.

Infrasound waves have a frequency of less than 20Hz and cannot be heard by the human ear.

Xie Weishi nodded. "Yes. The amplitude of this infrasound wave should be close to that of the human brain, which can cause resonance in the human brain, thereby causing strong stimulation to the brain, causing fear and anxiety and even madness. The exact impact depends on how often the brains of different people vibrate. He glanced at Fang Chi, "Obviously, it resonates with your brain." ”

"Destroy first, then rebuild, and then control." Fang Chi said in a low voice, "This is the principle of addiction and hallucination of ice cracking. ”

"Yes." Xie Weishi said, "You know LSD hallucinogens, right? ”

Of course, Fang Chi knew about LSD hallucinogens.

The scientific name of LSD is D-diethylamine of carbic acid, which was synthesized by chemist Albert Hoffman in 1938. This LSD hallucinogen, which only needs 100 micrograms, can cause a normal person to hallucinate for 6 to 12 hours continuously. This dose is less than one-tenth of the weight of a piece of sand.

LSD hallucinogens were widely abused in the hippie cultural movement of the fifties and sixties in the West. People see taking LSD hallucinogens as an unknown trip. During this trip, it is possible to see distorted time and space, magical worlds, feel the soul out of the body, and the body flying in the air. They can even go back in time and step into their own disorganized memories.

Although LSD is not as physiologically dependent as drugs such as Heroin, it can cause social danger by causing perceptual impairment. So nowadays, countries around the world list LSD as a banned drug.

At the beginning of last year, the 19th Bureau monitored a large number of LSD hallucinogens on the dark web, and Fang Chi received instructions from Hong Jincheng to intervene in the investigation as Medusa, and found that all clues pointed to a multinational drug research and development company focusing on mental illness - Neurose.

In March, she submitted an investigation report to the 19th Bureau, reasonably suspecting that Nerve Rose was engaged in the research and development and smuggling of a new generation of hallucinogens.

In April, the "Fox Hunt" task force for Nerve Rose was established, with Sheng Qinghuai as the leader of the operation team, Medusa entered Nerve Rose as an undercover agent, Sheng Yan served as the commander of the special operation team, and Medusa was the liaison.

After entering Nerve Rose, Fang Chi discovered that the company was very cunning and was not involved in the production of hallucinogens. They sell their formulations of hallucinogens to illegal drug manufacturers abroad for high licensing fees. However, Nerve Rose's drug research and development office in China is highly confidential, and Fang Chi has repeatedly tried to get close to Nerve Rose's CEO Zu Feng and several other executives, but they have found nothing but to learn about the research progress of the new generation of hallucinogens. The investigation was blocked.

In September, a new generation of hallucinogens "Siren" was successfully developed, and Fang Chi obtained accurate information that the synthetic formula of "Siren" will be traded in Myanmar's Shan State and the Golden Triangle drug lord "White Crow" on October 2. Medusa will participate in the deal as a member of the side of the Nerve Rose. The "Operation Fox Hunt" special team is on standby, and in conjunction with Interpol, is preparing to take down the Nerve Rose and the "White Crow" gang in one fell swoop and wipe them out.

On October 2, the transaction went ahead as scheduled. In the process of handing over the recipe*, the "White Crow" gang suddenly kidnaps Medusa and shoots another Interpol undercover member of the gang.

Interpol sprang into action, and a fire broke out. In the face of this sudden incident, the "Fox Hunting" special operations group had no choice but to immediately react and join the battle. Sheng Yan was captured in order to capture the box containing the recipe for the "Siren Siren".

However, in the end, no one expected that the box that Sheng Yan exchanged for his life was empty.

Xie Weishi was stunned when he saw Fang Chi and asked, "What do you think?" ”

Fang Chi suddenly came back to his senses and said, "I know." She asked, "You're trying to say that ice cracks are more similar to LSD?" ”

Xie Weishi smiled lightly: "Smart." ”

Fang Chi thought about it and said, "Your comparison is indeed reasonable. Ice cracks, like LSD, are emotional and sensory disorders, unlike drugs such as heroin, which can cause direct damage to human tissues and organs. ”

Xie Weishi smiled lightly: "For example, LSD's classic 'retrospective experience' (1) has appeared in you. Didn't you say that the music from the Ice Crack is still replaying in your head? ”

Fang Chi said gloomily: "It's still there now." ”

Xie Weishi said: "That's right. In fact, I guess the addiction is similar. People who have seen ice cracking will not really become addicted. They will want to watch it again, but it will be as if they have eaten something delicious once and can't help but want to eat it again. ”

Fang Chi said: "Goodtrip (2)? ”

Xie Weishi laughed, "Yes, Goodtrip." LSD also gives people badtrips, but I'm guessing ice cracks artificially reduce the probability of badtrips. ”

Fang Chi nodded, but there was a little shock in his heart.

Xie Weishi's words seem to be light and light, but in fact, there is another meaning behind it - the experience brought by ice cracking is random. Each seed brings a different experience to people.

Xie Weishi only watched the ice crack once, and he could deduce that every experience of the ice crack was different. In this way, he said that he was basically able to reverse the ice crack, and it was not a boastful remark at all......

It was also at this time that Fang Chi suddenly realized that the experience brought by the different seeds of ice cracking was different. Thinking of the last time I saw the girls in the "Black Iron Age", the reactions were indeed different.

Each seed of the ice crack is perfectly simulated by a trip similar to LSD through the virtual reality. But to be able to eliminate those badtrips in LSD, isn't this something more terrible than LSD?

A thought suddenly crossed his mind like lightning and fire, and Fang Chi couldn't help but shudder. She asked Xie Wei anxiously:

"Since you can reverse the ice crack, can you roughly deduce who did it?"

Xie Weishi was stunned for a moment, and there was a flash of fluctuation in his deer-like eyes. "I can't deduce it," he said. ”

Fang Chi was so keen, how could he let go of the momentary change in his eyes? She asked, "Don't you feel anything?" Like, like who did it? ”

Xie Weishi shook his head, his eyes darkened. "When I watched it, there was a moment when it felt familiar. But it can't be. People I know wouldn't do such a thing, and ...... It is impossible to do such a thing. ”

Fang Chi was disappointed, but he heard Xie Weishi say again:

"Ice cracking wasn't done by one person, it was done by a team."

Fang Chi's eyes froze, and he secretly clenched his fists.

On that day, Hong Jincheng told her that since the last fox hunt, Nerve Rose had stopped the research and development of banned biochemical drugs.

Originally, she had never been able to get a glimpse of the situation of the mysterious real yàn room, and now that the research and development operation is stopped, it is basically impossible to get evidence from this line.

But will Neuro Rose really wash its hands and become a clever pharmaceutical company once and for all?

She didn't believe it!

Although Fang Chi does not believe in the inherent evil of human nature, he believes in genetics. If a company emerges and exists with the gene of "evil", it is impossible for it to completely embrace the light.

The appearance of ice cracking, such a coincidence in time, is like filling in after the development of hallucinogens has been stopped. Without the Siren, it still has an Ice Crack. Isn't Ice Crack the perfect inheritance of the Siren?

Fang Chi's chest churned violently, and he had a splitting headache, and strong anger, hatred, and hatred surged in his heart, stacking up a fanatical desire for destruction.

No, it was just her Fang Chi's intuition, her sixth sense.

There is no evidence that the ice crack was the work of Nerve Rose.

She could only investigate with reasonable suspicion.
