【Summer Five】Iron City Wall

Lao Chen asked the two to put away the goggles, went into the compartment and took out a pocket, packed up his things, turned off the lights and left.

"Come on, Wang Lao Er's bastard has given you to me, so you can't just leave it alone here?" The short old man said with his waist in his arms, his tone was still fiery, but his expression wasn't too impatient.

Xia You bent down and panted for a while, finally regained his strength, and left with Lao Chen through the main entrance against Manchangzi's probing eyes.

The forge is not far from the arena, and there are scattered shops around it, which can be regarded as a "city center".Old Chen led them into the crowd, weaving back and forth in the alley where the street lights couldn't reach, and gradually put the noise into the distance.

About 10 minutes later, a two-story bungalow came into view.Compared with the black walls and gray tiles that are common in the big cavity, this house has the characteristics of NO.13 melting furnace - vivid and tidy, like a place where living people can live.

"This is it. The first floor belongs to me, and the second floor is free for storage. You..." Lao Chen frowned and thought for a while, then reached out to remove the nameplate in front of the house, and said, "You can live in the attic, the environment is good."

Wutiao looked at the strange-looking "Chen" on the nameplate, and said, "Can you still afford a house?"

Perhaps because he was in a good mood, Old Chen didn't bother with him: "Fuck you, I've been working here for thirty years anyway, and I can't even own a house?"

Wu Tiao wanted to say more, Xia You coughed a few times quickly, overshadowing what he was about to say. "Then thank you, Master Chen, and please take care of me in the future."

Lao Chen took out a bunch of keys from his pocket, fumbled around in the pile of keys that looked like a banana tree, and finally picked out one and handed it to Xia You. "Okay, from now on you will come to the factory to report during the day, and the rent will be deducted from your salary and settled on a monthly basis."

A pretty good deal.The forging factory is a job with quite a technical content, and it is also close to the arena, so it takes less than half an hour to go back and forth.Since Wang Laoer agreed to take them out, the only thing to worry about was the funds—it must not be cheap, but fortunately, there was still half a year to prepare.

Xia You took the key, thanked him again, and led Wutiao into the house.

The first floor is a messy living room. Looking at the furnishings, one can tell that the owner is a hot-tempered old man: the clutter is so piled up that even the cabinet can’t fit in it, but the tea table in front of the sofa is clean and dusty. On it, there is no scratch on the surface of the teapot.

Go up the stairs to the second floor, it really is a place to "put things".It seems that Lao Chen moved an entire miniature forge here, with all the equipment needed for all processes, and even a special negative pressure compartment to store the driving fluid.

"This person is terrible." Xia You sighed, "The production line has been moved here intact, and there is still leisure to drink tea and walk the birds?"

Wu Tiao tapped on a certain branched pipe, rubbing a thin layer of dust on his knuckles: "What's the matter, he hasn't touched anything here for a long time, it's a waste of life."

"Are you interested? If you want to come to him, the old man will not be stingy about lending it to us, just ask about it another day."

Stepping up the stairs again, the ceiling suddenly narrowed, almost brushing past five strands of hair.He had to "bow his knees" like a hermit crab with long arms and legs.

Open the wooden door with a key, and a boxy hut suddenly lights up.

Directly opposite is a window that spans half of the wall. There is a street lamp just outside the wooden corner, and the light floods into the room in an even way. It has to be covered with curtains so as not to be glaring.Although it is an attic in name, the space inside is not small. The bed, cabinet, desk and chair are fully equipped with all internal organs, and a small shower room is also set up.

The previous owner seems to have left not long ago, and the utensils in the house are neat and clean, but there is no dust like the second floor.

"There is still a portable tool box?" Wutiao took out a box from the corner in surprise, jumped to the table, pulled out the chair, and put all the tools on the table.He took out the chip that he had been playing with for a long time from his pocket, and made a gesture to dismantle it, but he didn't forget to turn his head and call Xia You: "Come on, there must be a big discovery this time!"

Xia You doesn't want to talk to him, Xia You just wants to sleep.

"It's because you don't feel tired." He took off his coat, kicked off his shoes, and fell straight on the bed, "But I'm so tired, I'll talk about it when I wake up."

Wujo rolled his eyes in dissatisfaction, and turned around muttering "trouble".As if he thought the chair was too narrow, he bent his legs and stepped on the railing, his back slightly arched, and his collar was pulled down a few centimeters, revealing a small section of the back of his pale neck.

Between the bones of the pair of fluttering butterflies, Xia You vaguely saw a number.

It was pitch black, neat, with hard edges and corners, deeply branded on the five backs as smooth as snow peaks, cutting off the ridge in the middle.It is like a series of hideous scars, but it subtly adds a sense of sacredness to the five - just like the Holy Lord carrying the Iron Cross, the blood flowed all the way, and the black soil and chalk were created under His feet, spreading into a never-frozen river.

"86", that is the number Xia You has long been familiar with.Three years ago, he saw the value of Wujo by chance, and he was not surprised by it: Satoru should have come from that resplendent place, where he grew up bathed in carols and flowers.

But when he lay drowsy on the soft bed in the attic, the number seemed to start to squirm and melt; the jet black twisted violently, as if something was struggling to break out of the cocoon—as if the appearance composed of 8 and 6 was about to peel off ,collapse.

But the drowsiness was overwhelming, Xia You couldn't hold on any longer, and fell into a deep sleep.

When I woke up, the smell of food wafted faintly in the air.The voice of the conversation was filtered by the door panel, and it could only be heard that they were arguing.

Xia You slowly got up, put on her clothes and went downstairs.

Sitting at the dining table, Lao Chen and Wu Tiao were arguing over the "feasibility of nanomaterials in the application field of drive armor".There are simple three dishes and one soup on the table, which is much worse than summer oil, but it is still fragrant.

It's a pity that the two people who were sitting upright wanted to fight to the death, and neither of them moved their chopsticks.

Xia You, who was still a little confused, sat down in the vacant seat without raising his head, and started eating by himself.

When it comes to quarreling, no one can match the five skills-you can never beat a person who will not get angry.He can only make sarcastic remarks in one sentence, and squint at people with a calm to mocking expression, making the person sitting across from him want to punch his beautiful nose bridge.

Therefore, Lao Chen's unilateral struggle ended in failure.He found that he couldn't refute the five points no matter what. The silver-haired boy was like a tumbler, and when he leaned back cheerfully, the anger of others was emptied, and there was no trace of it.

"The dishes are getting cold."

Xia You, who was holding a bowl, said so.

With a fluttering sentence, Wu Tiao curled his lips, always thinking about what to say.Xia You seized the opportunity to pick up vegetables and stuffed them into his mouth, blocking the guy's sharp teeth on a physical level, so as not to make Lao Chen so angry that he would smoke.

After dinner, Wujo couldn't wait to drag Xiayou back to the attic, showing off the results of his hard work all afternoon.

"As we guessed," he said, "the recognition program in this chip... even the bottom frame is reversed. The logic chain is reversed, the basic code is reversed, but the calculation result is not much different from the conventional version."

There were old disassembled chips lying on the desk, and something was humming in the corner.Xia You carefully bypassed the parts, and took a look: the thing had thick walls, complicated wiring, and dense codes scrolling on the screen—it was actually a computer!

"You..." Xia You didn't know what to be shocked by for a moment, "Where did you get it?"

"Ah, you mean this old thing? It's downstairs. It's useless anyway, so I'll borrow it. I didn't expect it to turn on. It's a bit slow. It's feasible to run a test program."

Wutiao didn't have the slightest sense of being reckless, and slapped the case: "Forget about this stuff, I'll just say the conclusion: If Big Hollow is really mass-producing such chips, it means that reverse logic is highly feasible. "

"Do you remember what Uncle said about the 'dual theory'? Although the biochips used on the surface, and even our own, are against it, the functions of the final implanted systems are almost the same. All manufacturers who have tried to imitate the chip so far They all failed, their products couldn't pass the audit of 'Walden Lake', and were blocked by the firewall at the top layer, but I bet - the underlying logic of these chips must be to 'overwrite the original information' rather than 'create New information'; because existing technology does not support them going any further. But..."

Speaking of this, Wu Tiao's speech speed gradually became faster, the end of the sentence was raised high, and the light in his eyes became more and more bright.

Xia You was captured by the light, and almost subconsciously said: "If the reverse architecture is proved to be feasible, the combination of the two may be able to achieve a cross-generational technological breakthrough—"

He wasn't sleepy at all, and this conjecture was crazy enough to burn out all reason and make all the academics raise their glasses to revelry.

"—we can deduce the source code of 'Walden'."

The second half of the sentence was as light as a feather, and it seemed that the parties could not believe it.

Wujo laughed.He saw the same excited self in Xia You's eyes, shining brightly like the rising sun.

"Get the source code," he also lowered his voice, like a giant python seducing Adam: "You have taken control of the nerve center of the iron city wall."

An absurd, outrageous delusion that reaches the sky, can be called a daydream, but Xia You can clearly hear her heartbeat pounding.One click, two clicks, three clicks, rising and falling with the tide in the five eyes, like a ram triggering the trigger, a kind of fire flashes past the lightning.

He took a deep breath and shrugged his shoulders back, showing a little tension.

"At this stage, it's just a theory within a theory, and I don't have much confidence. If the reverse chip only circulates in the big hole, there may be craftsmen with better knowledge here; at the same time, once we leave, all resources and channels will be completely cut off. "

The attic was so quiet that there was a sound of needles falling, the desk lamp illuminated a corner, and a yellow halo fell on the table.The disemboweled chip lay horizontally in it, the computer glowed weakly, and the screen flickered a few times from time to time, the code froze for a short time, and soon flowed as usual again.

The five blinked, and the slender eyelashes trembled slightly, like the lingering fog in the forest.Behind the dense fog is a blazing fire, burning with the desperate spirit and drive of young people.

"So what?" he said softly, "As long as we find the answer before we leave, everything will be solved."

"No one else can, we can—only we can."

Xia You looked at him for a long time, then smiled slowly.

"Yes, you and me."

These three words seem to have been brewing on the tip of the tongue for a long time, until they exude a mellow grape fragrance.

"There is nothing in this world that we cannot do."
