After Shi Fei woke up, his body was still very weak.

In particular, the various visual illusions that appeared after being illuminated by the comet robot with those rays of light still appeared in his eyes and brain from time to time as he traveled north, and then disappeared immediately and inexplicably.

What's even more infuriating is that it may really be the same as what Comet said, his brain is implanted with a huge amount of knowledge and information, and whenever Shi Fei sees some items and creatures that he has never seen, his brain will automatically pop up a lot of information about these strange things, which is outrageously detailed.

"Mobile phones, communication devices in the 21st century. It has been eliminated decades ago, and can take pictures, calls, make friends, etc., and is known as the harvester of human soul and time......"

"QR codes, encoded decades ago, can be used for information identification, payments, and ......"

"Oil, backward energy, polluting, once historically black liquid gold, can be used for electricity, power, heating and other purposes......"

"The saber-toothed leopard, a solitary animal, is a product of human genetic synthesis and modification, a failed breed, fierce, cunning, and lethal......"

Shi Fei's brain seemed to have become an encyclopedia, and his intelligence seemed to have improved more than a little bit.

He finally understood what the comet meant by transforming and activating the potential of his brain, and what it meant by "use your brain well".

Comet was about to die, and when he had no other choice, he chose Shi Fei, who had destroyed it by mistake, as his inheritance, and stuffed the information it had into his head.

That's why he was in the Light of the World Building to find a life-saving escape passage; That's why on the way north, a lot of inexplicable images and information kept appearing in front of him—because these information and images had been stored in Shi Fei's mind.

It's not a good thing to be too smart, and sometimes he can't stand it anymore, so he will slap himself on the head a few times, and will drive away the annoying images and words a little.

In his spare time, Shi Fei also tried to control the so-called "Morning Star System" that appeared in his brain, and he found that after a long period of exercise, he could already turn on and off this virtual system in his brain through concentration.

He also read the small explanatory text countless times, and finally understood what the system that suddenly appeared in his mind was.

This thing, absolutely awesome! This is a system developed by Comet to develop the potential of the human brain.

Many people have dreamed of eating all the knowledge and information into their stomachs like food, and then absorbing them into their bodies like nutrients and becoming a part of their bodies.

Comet has come up with a very practical solution, which is to burn information and knowledge into the brain.

The potential of the human brain has great room for development. Even the smartest people develop up to 2-3% of the brain's potential.

How to quickly and effectively develop ordinary brain abilities to the maximum? Comet integrates all the information and knowledge it has, and in addition to burning massive amounts of information into the brain, it also creates a knowledge growth system that can be installed in the human brain, which is the "Daystar System".

The cow of this system lies in the fact that it can retrieve all the required knowledge in the brain through people's active learning and evolutionary selection, form a knowledge system, and constantly strengthen the proficiency of knowledge and skills in a certain field, and eventually become an expert in a certain field.

"Awesome! If I wanted to be an expert in printing money, would that be possible? After Shi Fei chewed on these words, his first thought was that if he could master the technical ability to make coins, then he would not be short of money to spend in the future.

From dream to reality, the reason why Shi Fei has such an idea of a turtle is forced by life.

The practicability of this system has not yet been verified by Shi Fei, but the problems brought to them by the real world are becoming more and more severe.

The scarcity of goods, the collapse of the economy, led to the depreciation of money.

Along the way, in the midst of the influx of refugees, the currency Bella has gradually lost its value. Shi Fei had several stacks of Bella cash hidden in his pocket, and he couldn't even get a little bread and milk at a grocery store.

"I want all this bread and milk!" A middle-aged man who looked dressed fairly well, squeezed away a few customers who were already yellow-skinned next to him, and put a bundle of Bella cash in his hand on the counter, immediately making the few stacks of thin cash that he was scrambling to buy next to him look extremely shabby.

In a crisis, buying things depends not only on ability, but also on whether there is enough cash. Warehouses in many places have long been turned into auctions for the rich. The rise in the price of materials has long made ordinary people out of reach.

It was the hackers who chased wild animals and dug vegetables and fruits in the field all the way, and the two barely survived.

Therefore, Shi Fei touched his belly, which had lost four or five pounds, and comforted his internal organs: "When I learn the skill of printing money, I will definitely carry a few bundles of cash to purchase, and big fish and meat will serve you!" ”

The blackout war has destroyed the whole world.

The two men headed north, all the way in the ruins of the city. High-rise buildings have collapsed, and the ground has been blown to potholes.

Not to mention the farmland on the outskirts, there is hardly any greenery to be seen. On the one hand, the devastation of the war, and on the other hand, due to the shortage of food, all the edible plants were plundered by the refugees.

Along the way, they encountered refugees from all over the country, who marched in droves towards the few remaining large cities in the south, the Federation.

The federation of these large cities still has some remaining industrial production capacity, and there is always some hope of survival.

Some of the refugees walked and some drove, but when they drove, the vehicles had no energy and nowhere to replenish them, so they had to throw the cars away and walk on foot.

Everyone still has some dry food or canned food on them, but they don't starve to death, but they eat these things every day, and they inevitably feel nauseous and malnourished.

But do they have any other options? The only choice is to change the canned food in your hand to other people for some canned food with different flavors, and change the taste to talk about **.

Seeing Shi Fei and the hackers going north, the refugees all showed surprised expressions, going north, what else is there besides more scarce supplies and colder weather? They smiled kindly at the two of them on the surface, but in their hearts they were calling them "stupid".

After waking up, Shi Fei began to gradually feel the power of the extremely cold weather in the north, and also moved the idea of turning back and going south.

Shi Fei expressed this meaning to the hacker, but at this time, the hacker seemed to admit his death, and did not listen to his opinion at all, but looked at the north with a determined face, as if he was going to make a pilgrimage to some sacred place.

In the destroyed world, it is difficult to find something to eat, and basically some supermarkets, warehouses, granaries, and even fields that are stocked have basically been moved by the refugees.

Shi Fei searched everywhere and found some canned snacks that had fallen into the corner. I can't get enough to eat, and the weather is getting colder.

There were several days of heavy snowstorms and snowstorms, and the two of them had nowhere to hide on the road, Shi Fei relied on the first-level engineering and construction knowledge opened in his mind, and picked out some haystacks, wood, metal, and iron sheets, as if there was a drawing reference, and actually built a temporary small house for two people to live in.

Shi Fei was amazed, because all the material dimensions were intercepted, there would be accurate scales in his eyes, and every detail would be prompted, and the seemingly complex building construction was like building blocks in his eyes.

Although the small house was built temporarily, it was not simple at all, with a sink to collect melt water, a small warehouse to store stored food, and a small exhaust and ventilation pipe, so that there was no danger of even a fire inside.

With the assistance of first-class engineering and construction knowledge, the temporary small house has withstood the test of heavy wind and snow after completion, and it is extremely comfortable to live in, the wind cannot blow, and it is still warm, like a shelter in the ice and snow.

The hacker looked at the small and well-equipped room of the sparrows, and saw that Shi Fei's eyes were different, and he couldn't help but stretch out his thumb to express his appreciation, and immediately picked the most comfortable position, and spread his body comfortably into a big character.

As a complete layman, he suddenly had such mature cover skills, Shi Fei was suddenly full of expectations for this "Daystar" system.

Maybe there's a skill upgrade for printing money or smelting gold!
