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

Although the humanoids have extremely strong energy, as long as they wish, they can remain in a normal state of wakefulness until their energy reserves are exhausted.

But hibernation is also beneficial to the humanoid. When the main personality enters hibernation, it will trigger the core's automatic maintenance mechanism to process the redundant data accumulated during activity.

This is a sign of relaxation, Raphael thought. She turned around and looked at the lights of thousands of houses below getting farther and farther away. She felt that the atmosphere on the plane was a little tense - she thought that the word "expectation" would be more appropriate.

Although the voices of the people around me were lower, the pitch was higher, and there was something sneaky in it.

This is an academic exchange, not an espionage activity... The academic community is very interested in the fully simulated neural network reconstructed based on human brain scans, and hopes that this time there will be gratifying progress.

Academic exchange... Raphael pondered, it seemed that it was not impossible to steal data.

Soon the conversation was reduced to a harsh whisper, and her reflection in the glass seemed to ask her if she wanted to try to participate in such a ridiculous thing.

As they flew across the North Atlantic to Germany, the endless black ocean lay below them.

Perhaps it was approaching the coastline. Looking down from Raphael's side, he could see bright lights in some directions, and those cities that stayed awake all night were in a warm glow.

But the further north you go, the smaller the bright area becomes, and it is not as bright as the southern side of the continent.

Everyone on the plane noticed the difference and conversations became quieter.

Raphael judged altitude the same way most passengers did: based on what she could see.

But at this moment the ground looked pitch black, making it impossible for her to make any judgment.

When the sound of the plane's engine gradually faded and the side pressure bank began to make a sharp left turn, she knew they were almost there.

Then, the slight vibration of the flaps being lowered was transmitted into the cabin, which meant that the pilot had completed the landing configuration preparation.

After a while, you can see green plants flashing quickly outside the porthole.

The pilot's voice came over the radio, asking smokers to put out their cigarettes, the flight attendants to clean up the drinks, and everyone to fasten their seat belts.

Five minutes later, they landed at Hamburg International Airport.

In the cockpit, people's conversations became heated. The crew members began to get busy and the passengers became excited.

Only a small number of people got off the plane at this time, while the rest remained on the plane, waiting for the next transfer.

Raphael sat alone, watching those who were leaving get into the German-made cars and leave quietly.

Well, if I hold on for a while longer, I’ll be able to have a good sleep.

……

When Lingyin was awakened by the beeping alarm of her watch, she felt that the weather was a bit cold. It was already ten o'clock in the morning, and there was still thick frost on the windows.

She rolled out of bed, realizing that she hadn't checked the heating in her suite before going to bed. She stepped across the floor barefoot, crouched in front of the room temperature controls, and tried to adjust the room's heating.

This is the sixth floor of the hotel - a "family travel suite" with independent kitchen and bathroom facilities - and the huge floor-to-ceiling windows allow tenants to overlook the large courtyard below.

The sky was gray and low-lying with clouds, as if it was going to snow. It was only October.

"That's terrible." Lingyin thought to herself as she walked towards the bathroom. She knew the situation might be worse than she thought.

They were arranged to stay in this room because the expatriate official who usually lived in this apartment had returned to the United States.

She turned on the faucet, and the water was still hot. But she found a note on the mirror of the small medicine cabinet in the dry area of ​​the bathroom, which read "Please don't make a mess like the last guest who stayed here did."

Then she glanced at the small refrigerator in the kitchen, which was filled with various alcoholic beverages.

The area least affected is Europe. Only a very small number of areas have been affected by the collapsing radiation cloud, but the numbers are not very high. Taking medicines for the corresponding symptoms can protect you from the hazards of the collapsing radiation.

After entering the bathroom, she began to wash and comb her hair.

If nothing goes wrong, this oversized hotel room will be their living space from now on. Lingyin bit the hair tie, combed her chestnut hair, and tied it into a side ponytail.

"Oh, good morning."

Raphael heard footsteps, opened his eyes, lifted up the hands and feet that were on his body, and struggled to climb out of the embrace of No. 4 and Asuka.

"Do humanoids also need to deal with jet lag?" Lingyin greeted her. "The coffee is over there, but it's not heated up yet."

"I like to call this exhaustion travel shock."

Raphael staggered to the coffee pot, lifted the lid and took a look.

"Nothing at all!"

"We have instant coffee, do you want it?" Lingyin said as she threw out a small plastic bag.

"No."

Raphael didn't even bother to raise his hands, letting the unknown instant coffee bag fall to the ground.

"Hey," Lingyin felt that Raphael was a little disdainful, so she asked, "Where are they?"

"They are still hugging each other. There will be some fun to watch later."

"That's terrible, you man."

Although Lingyin seemed to be criticizing Raphael's evil intentions, her eyebrows were actually curved. Her desire to have fun could not be hidden from the people who knew her best.

"Want to go out for a walk? I want to go out for a walk, but——"

"Two of us go together." Raphael nodded.

This rule applies to those who participate in this academic exchange and are determined to stay for a long time. This phase of the exchange will involve sensitive issues, so the rules for the exchange team are temporarily much stricter than usual.

"But it may not be possible today. The German side has not issued us a pass yet."

At this time, bursts of quarrels, faint rustling sounds, and the angry screams of birds came from the living room.

Raphael and Lingyin stood outside the door, each holding a cup of coffee, watching the fun.

"…Well, let's take a chance at the hotel," Lingyin suggested.

"breakfast!"

Raphael looked at his watch and decided to find something to eat to satisfy his appetite, such as sweet pastries.

In fact, Lingyin was right. Tactical dolls did not have any problems with jet lag. They just felt that they needed to appear "different" in order to blend into the surrounding environment.

There were not many people walking in the corridor. Occasionally, you could see a guy in a black suit and tactical glasses patrolling with a serious look on his face.

They looked in a hurry, as if something had happened recently that was worth making them nervous.

However, on this ordinary morning, there was no sign of chaos.

Chapter 2 Social Dinner

The only reason it was peaceful and quiet was because this neighborhood was not affected by the march.

After taking a quick walk around the hotel twice to find out the location of the emergency evacuation passage and the material grade of the fire door, Raphael and Lingyin returned to their guest room in the harmless manners of little white flowers.

The clouds that blocked the sun began to sprinkle snowflakes onto the ground. The American academic exchange group gathered in the hotel lobby, then filed out and got on their respective shuttle vehicles to attend the dinner that was held to welcome them.

Raphael was in car number 4 - she noticed that she seemed to be placed a little forward this time, and she couldn't tell how she felt.

As the motorcade began to move, she touched the pistol tucked into her thigh. Dresses were designed to accentuate the curves of a woman's body, and there was no way to hide an object like a pistol.

Moreover, such buffet banquets are mainly for social purposes. The other party is not a military unit, but just a research institute with some government background. The most appropriate attire is indeed an evening dress.

Raphael closed his eyes and took a deep breath, secretly telling Asuka and Puppet No. 4 that they could give their best.

Lingyin sat on the other side, resting her left arm on the car window, looking at the heavy snow falling outside with boredom.

"How many people will freeze to death this year?" she asked suddenly.

"Refugees will keep dying. Don't think about it. It has nothing to do with us."

Raphael closed his eyes and rested. The roads in Berlin were actually the same, with only a few potholes. The car bumped eastward, passing through the streets in the city where there were few vehicles and pedestrians.

Occasionally, a few passers-by wrapped in thick coats could be seen walking slowly in the snow. In the flashing streets, there were faint lights flickering, and people could be vaguely identified nearby.

It can be basically confirmed that those people who were keeping warm were refugees. They might be homeless people caused by the previous Russian Civil War, refugees from the Russo-Ukrainian War, or refugees affected by the disaster at the Nobuoyama ruins.

In any case, they have no future. These people will die in the severe cold that will come soon, and only a few lucky ones will see the beginning of spring.

Crossing two streets, Raphael saw the hotel where the dinner was held emitting bright lights. The nearby streets were brightly lit, and wealthy people were happily skating, having snowball fights, and making snowmen in the heavy snow.

Seeing people immersed in real joy, Raphael reminded himself that it would be best to forget about the refugees hiding in corners to escape the cold and focus on what was happening in front of him.

She would never do such a stupid thing as trying to stop a chariot with a mantis arm.

The convoy turned a few corners and stopped in front of the hotel. It was a medieval-looking building with a well-maintained exterior.

The birch trees growing between the gray reinforced concrete and asphalt road were now bare, stretching their lifeless branches toward the snowy night sky.

A few hours later, when the snow weighs down the branches, this lifeless scene will undergo a complete transformation.

"...The temperature is around 0 degrees Celsius," Ling Yinti reminded as she put a small cape on Raphael. "The global temperature change is really serious."

"Well, there's a lot of dust being pumped into the stratosphere, and those particles, which don't look like they would do much harm, actually reflect a lot of sunlight away."

“Is this the legendary nuclear winter?”

The nuclear winter mentioned by Lingyin is a hypothesis based on a digitized model, that is, the explosion of a large number of nuclear weapons causes a large amount of smoke and dust to enter the Earth's atmosphere, causing the upper atmosphere to warm up and the surface temperature to drop, producing an effect opposite to the greenhouse effect, making the surface appear like a severe winter.

"Not really. Optimistically speaking, the global temperature will warm up next year, and it won't be until 2038 at the latest. Just bear with it."

After the Nobuoyama ruins rose to the sky, the nuclear physicists who got the news started thinking hard and published several articles about the meteorological impact in journals at the speed of light.

The nuclear winter that will lead to human extinction and mass extinction of biological species, as predicted in the past, is still a long way off. Even if all the existing nuclear warheads of mankind were taken out and exploded in one go, this would not be possible.

The wind had almost died down.

The snow was falling heavier.

She nodded to Lingyin and followed the waiter who came to greet her towards the hotel door, feeling the air was gloomy and cold.

Before I even walked in, a wave of heat hit me from the open door. The heating was turned on too high.

Raphael immediately took off the outer garment she had just put on, which made the tuxedo-clad waiter beside her twitch his eyes. Okay, this must be some young lady who was forced to leave home to attend a social event.

Diplomats from the United States and Germany gathered together, holding glasses of champagne and chatting, occasionally letting out low, suppressed laughter.

The voice sounded fake and artificial, but in this kind of situation it gave them an inexplicable label of being polite.

According to the schedule, everyone had to attend the 90-minute social reception before going to dinner.

After dinner, we will attend a classical music concert.

Raphael hated the social cocktail party and the buffet that would follow, but was looking forward to the classical music concert.

When talking about classical music concerts in Europe, people will inevitably think of the Berlin Philharmonic Orchestra, the Vienna Philharmonic Orchestra, the Bavarian Radio Symphony Orchestra, the French National Orchestra, etc.

But there is still a long time to go before attending the concert.

Raphael took a cocktail and walked to the corner of the banquet hall, acting as a nobody.

The lighting in the banquet hall was not very sufficient, probably so that everyone could enjoy the snow scene outside through the floor-to-ceiling glass windows.

The expected harassment and face-slapping plot did not happen, which made Lingyin, who wanted to experience the treatment of the protagonist of a movie, TV series or novel, quite disappointed.

They walked together to the corner of the banquet hall, their eyes always fixed on the snow scene outside the window, and the aura of rejection emanating from their bodies was obvious enough.

This is a public place.

The people present were not only members of the two research institutes, but also officials from government departments. If one accidentally caused trouble, it would probably spread to several circles the next day, and then one's career would be ruined.

Tonight was supposed to be a social dinner, and Germans wouldn't entertain their guests until they couldn't stand it anymore.

……

Max Planck Institute for Brain Research, Frankfurt.

The level of preparation for this computer simulation is unprecedented. They have never done an experiment in this way before, and that is exactly what this experiment is designed to do.

The human brain's ability to learn and remember comes from a complex network of nearly 100 billion neurons and synapses interconnected.

Although people have built neuronal models and discovered HEBB learning rules——

In the human brain, repeated stimulation of a presynaptic neuron to a postsynaptic neuron can lead to an increase or decrease in the efficiency of synaptic transmission.

——It has been more than 60 years, and we still don’t really understand the actual operating mechanism of the brain.

This is an extremely rare simulation experiment. The biological data loaded into the system comes from real human brain scans. It took three years just to prepare accurate human brain data.

In the past, due to the limitations of the architecture of computing processors, humans could only simulate some of the human brain nerves in a very limited way. Even so, it brought endless ingenuity and a way forward to the researchers at that time.

This is not simply using a computer to simulate the working state of the human brain, but trying to make it truly "alive".

After all, the goal of brain-like intelligence is to achieve human-like intelligence or even general intelligence. The most fundamental challenge is the structural and functional complexity of information processing in the human brain.

When data appeared on the effect monitoring chart of the terminal, Karl Wilhelm Hartmann, the project leader of the human brain reconstruction project, was playing with the ballpoint pen in his hand.
