Eh? Do you also want to try the iron fist of the humanoid girl?

There is a traffic light in the middle of the road outside the subway station. At this moment, a gray-haired old man is pulling a huge suitcase in his hand, standing patiently at the intersection waiting for the green light.

However, it is obvious that more people lack this confidence, especially on busy roads, as if when a group of people run a red light together, it doesn’t matter what their quality is.

Anyway, everyone just kept passing by, knowing that cars wouldn't dare hit a group of people, so running a red light became a matter of course, and everyone just followed the flow of people around them.

The man looked at the crowd with disdain and laughed contemptuously: "Who among the people can remember the first time he ran a red light? If there is a first time, there will be a second time, a third time..."

The green light came on, and he picked up his suitcase and walked away with his back to the subway station exit.

A couple walking next to him showed disgusted looks when they saw the old man in his 50s dragging his suitcase shakily across the zebra crossing.

After they were several meters apart, the expressions of the young couple returned to normal.

To others, he looked to be in his early fifties, wearing a wrinkled suit of high-quality material and cut, and his hair was greasy and stuck together, as if it had not been washed for many days.

His eyeballs were slightly swollen and bloodshot, his face was covered with a layer of grease mixed with dust, and his whole body reeked of strong alcohol and sweat.

If it weren't for the suit, he might have been regarded as a homeless person by the police patrolling the street.

Just by looking at the direction the middle-aged man was walking, you could tell that he was a traveler.

There were many pedestrians going in the same direction, most of them dragging suitcases because they were all passengers planning to take a plane.

Some people looked even more disheveled than him. Not only did they carry a lot of luggage, but they also exuded a strong smell of fatigue, making people avoid them.

For people like them, no matter how crowded the roadside is, people will be kind and generous and make room for them for half a meter of comfortable space.

At this moment, he saw some eyes looking at him from a distance.

The professor looked back.

There were two middle-aged men standing there, one of them had an angry look on his face and was staring at him with his fists clenched.

The other one had a blank expression on his face. He just placed his hands on his abdomen and made a strange gesture, with his thumb and little finger stretched out and touching each other, and the middle three fingers gathered together. The whole looked like a diamond.

The professor understood and nodded slightly in response, with a barely perceptible smile on his face.

After walking this path, going through the luggage check-in procedures, and boarding the plane, you can leave this world that seems free but is actually extremely oppressive.

He didn't look at the two men again and continued walking towards the main entrance of the terminal.

Just before he was completely on the right track, the professor suddenly felt a pulling sensation along his arm.

He turned his head and saw that the person holding his wrist was a fair-skinned girl.

"Excuse me, is there anything I can help you with?" Professor Freud asked in a friendly manner, and tried to pull his hand away.

The hand that gripped his wrist didn't move at all, like a dead metal clamp.

"Professor Spencer, your laboratory... I remember you shouldn't go down this path. You still have four students to supervise and two important projects to lead."

"I... I just want to take a vacation." The professor paused slightly and clutched the suitcase tightly.

Raphael has seen too many people react like this. During this period of time, he has been running around and the targets he meets always react like this.

There are experts and professors, industry leaders, and blue-collar workers among the masses...

She didn't want to know what was wrong with these people because it had nothing to do with her. But when she saw the professor's message, Raphael became serious.

Professor Spencer's work

He is an expert in the field of biology. After teaching himself neural networks and deep learning, he adjusted his research direction to the topic of "how to simulate a brain".

——It is highly relevant to the second-generation controllable autonomous artificial intelligence that DARPA is currently developing.

As the earliest bionic humanoid, or the "core" that drives the bionic body to move, Raphael is most concerned about the next generation of his kind.

As this industry flourishes, the first generation of bionic humanoids, which have the worst functions and the worst safety, will inevitably face the problem of not keeping up with the times.

And "not keeping up with the times" is the dawn of true freedom.

In the cold wind, Professor Spencer forced out a pathetic smile. He kept clenching his fingers and turning his neck from time to time, maintaining the necessary body movements to drive away the chill that was gradually creeping over his body.

In this action, he used the edge of his vision to peek into the situation of his helpers.

"Who are you……!"

Chapter 172 Brain-like intelligence is the core of the second generation

"You are... already mature..."

"It's convenient to deal with smart people," Raphael was of course aware of Professor Spencer's little tricks, and she looked over without hesitation.

Asuka and Suzune had silently controlled the two people.

Looking at their stiff and slightly trembling expressions, you can tell how intimidating the cold touch of the gun muzzle against their lower back is.

Their faces were filled with panic.

"How did you do that?" Professor Spencer's face turned pale and his eyes almost bulged out.

The two girls were exactly the same as the girl in front of him who was holding him tightly, and their appearance was more similar than that of identical twins.

No, they are made from the same mold, there is no difference.

If we have to say the difference, it is that the personalities they project are different in their every move.

This is an obvious difference. The one on the left is cold and indifferent, controlling the target person in a methodical manner, while the one on the right is much more lively, making several faces and not worrying at all about the possibility of the prisoner escaping.

As for the guy who was holding him tightly in front of him, there was a faint smile on his face.

She took out a small box of mints, shook it, and calmly swallowed two sweet, slightly spicy, and slightly cool candies.

"How did they do that? It seemed to take a while, but they managed to do it."

There is no nutritional value in Raphael's words.

Spencer was furious. Those bastards at DARPA had already made it... but they were still using neural networks to fool him!

You should know that the human brain has about 1000 billion neurons, which have nearly trillion synaptic connections to communicate with each other.

They are interconnected to form an extremely complex network structure, which is called a "neural network".

In addition to neurons, the human brain also has auxiliary cells and immune cells that far outnumber neurons, such as astrocytes and microglia, which work together to ensure the functioning of this organ.

At the same time, the brain is composed of relatively independent brain regions, and different brain regions are also interconnected to form an information network communication.

With this understanding, researchers must focus on the basic unit of the brain - the neuron, which is composed of dendrites, cell body and axon.

The cell body can be regarded as a sophisticated electrical signal processing system. After receiving electrical signals from multiple dendrites, this tiny processing will integrate the collected signals and then transmit the integrated electrical signal along the axon.

Although it is accurate to say that chemical signals are received and then converted into electrical signals within the cell, the specific conversion process is not important to those who study neural networks.

Because what we want to simulate is the neural network, not to completely replicate the brain using biological methods.

After abstracting the workings of neurons, scholars like Spencer focused on how neurons are connected.

In fact, it is the connection between the axon of one neuron and the dendrite of another neuron.

This connection interface is called a synapse. The function of a synapse is to transmit signals from one neuron to another.

The key is that the most common synapses in the brain can be regulated by hundreds of chemical signals, such as dopamine, serotonin, adrenaline, etc. These common chemicals play an important regulatory role inside the brain.

If we have to abstract it, the functions of these chemicals are similar to those of logic gate chips, resistors, capacitors and other devices in complex circuits.

The effect of electrical signals is adjusted through different logic gates.

What people who study neural networks need to focus on is this electrical signal, which is actually the information of communication between neurons.

These neurons are connected to each other like wires, transmitting electrical signals, so can they be simulated using an electric stove?

The answer is obvious, absolutely.

To a certain extent, the electrical signals of neurons can be simulated using common capacitors and resistors to simulate the generation and propagation of electrical signals.

In the last century, two pioneers used the giant axons of squid to conduct experiments and provided a theoretical basis. After decades of development, Professor Henry Markram from Switzerland finally announced his plan to the public at the TED conference in 09.

He and his team will use supercomputers to build a brain model based on their understanding of brain structure, thereby simulating the human brain's 870 billion neurons and nearly one trillion synapses.

This project is not only about understanding the human brain itself, or the intelligence of the human brain, but it can even find another way to treat brain diseases.

Due to the limitation of computing power at that time, the project team could only simulate a small part of the mouse's neural network and proved its feasibility.

Considering the cost and complexity of using supercomputers to simulate the brain, another architecture and chip for simulating the brain was proposed - the neuromorphic chip.

This is a simplified analog chip that uses simplified neuron and synapse models to simulate the electrical signals of biological neurons.

As a result, the first product appeared in 14 and was a huge success as soon as it was launched. This is because the algorithm based on biological neurons can perform a considerable number of intelligent reasoning tasks.

But in order for it to produce true intelligence, the analog chips produced at that time were not enough.

The brain is just too complicated.

Professor Spencer looked more and more hunched over. He found that the group of office professors in DARPA who only knew how to play power games had gone even further than he had.

Fear, panic, and resentment towards myself for "choosing to escape".

How will the Bureau deal with him?

"No...there must be something wrong!"

He tried to take another step forward, but Raphael's hand remained motionless, holding him firmly in place.

"Brain-like intelligence is definitely not something that the Planning and Research Bureau can come up with!"

Professor Spencer screamed hysterically, but everyone around them avoided the "old man and the young man" who were in dispute.

In the distance, a police officer leaning against a police car, leisurely drinking coffee and enjoying donuts, cast his eyes over, but looked away the next second.

"Don't look, we have people all around here." Raphael reminded, "Professor, I think you should be able to face the reality."

She raised her left hand, revealing the dial to the professor.

"It is now 1925. Your transoceanic flight has finished boarding. If all goes well, you will be able to see the flight take off in a few minutes."

"..."

"What I hate most is resistance. If you don't know the current situation, you will suffer. Isn't it better to cooperate?"

Raphael muttered to himself as he quickly put Professor Spencer to sleep, then nodded to the two police officers who were enjoying breakfast across the road.

He gave a friendly wave and took two more bites of the donut.

Chapter 173 Fog

Just after putting Professor Spencer on the escort vehicle, Raphael received new news.

An officer of the former Russian Foreign Intelligence Service, who was employed by the CIA, snooped around and finally got a glimpse of information:

Foreign assets of the new Soviet Foreign Intelligence Service are investigating the situation of the bionic humanoids.

After taking over the Moscow headquarters, Obu immediately discovered treasures that had been deliberately hidden in past mission files in New York and Japan.

"It's over?" Raphael asked Fei Niao, "What do you think about this?"

"It's normal to be exposed. From the analysis of your memory fragments, the group in New York has already confirmed our existence. And that incident must be related to the Soviet strategy at the time."

"I would rather think that the Russians are trying something new."

Raphael pulled out his pistol and played with it for a while. "The higher-ups are expecting us to make greater contributions and to find all the spies."

"How is that possible?" Fei Niao shot and killed the temporary worker of the Russian Foreign Intelligence Service with two shots. An action team like this was insignificant.

A simple interrogation revealed that they were only doing this for the lucrative commission. After all, there was no danger, and they could get $20,000 for just providing escort services to an elderly man who was close to retirement.

Everyone has a price, and as long as the bid can overcome the other party's psychological defenses, he will definitely take action for the sake of US dollars.

Asuka closed his eyes and rubbed his temples with his hands.

It is simply impossible to find all the spies. It would be better to let those who have been exposed remain in their current positions so that they can be better controlled.

After cleaning out all these people and waiting for new people to fill the position, you won’t know where the rats will jump off to.

"Welcome to the real world of intelligence," Raphael congratulated.

"It's a mockery."

"That's not the case." Raphael explained, "Intelligence work is not easy. How should I describe it? Usually you can only find all kinds of possibilities.

If you express an opinion, you are taking the risk of being wrong.
