"Successful break-in, now into the compartment." Ye Chi pressed the headset and whispered--He is not alone in this bathroom.

"Wait, act when no one is around."

Ye Chi entered this bathroom not to squat in the pit, but to prepare to enter the ventilation duct.

But to get into the ventilation pipes, you have to tear down the fence, which is not a job that can be done silently - at least not by the person in the pit next door.

Ye Chi could only lean against the wall of the cubicle, taking this opportunity to recover his strength.

There are a total of 3 squatting positions in this bathroom, the ventilation duct is directly above the squatting position in the middle, and Ye Chi's squatting position is on the far left, and there is an old man skimming the squatting position in the middle......

Ye Chi felt that his nerves were much thicker now......

Finally, the sound of Ye Chi's long-awaited flushing sound sounded next door.

"Walk you!" Daddy said in the headset.

The drone now swaggered into the room and landed on the inner windowsill, using a thermal probe to monitor the outside of the door, and once someone wants to come in, it will warn Ye Chi.

Ye Chi stepped on the toilet paper tube on the partition wall of the partition room, and the space above the partition wall was limited, so Ye Chi could only dismantle the operation with similar stunts - his head rested on one side of the partition wall, and his legs were on the other side, so that his hand had a point of focus to remove the fence.

"Phew!" Ye Chi ignored a point, that fence must have not been removed for a long time, and as soon as he demolished it, a large cloud of ash fell on his body, almost blindfolding.

"Higu!" Ye Chi shook his head and patted it vigorously with his free hand - most of these ashes were wall ash or rust, and they were quite easy to shoot off......

He sat up from the wall of the cubicle, his head sticking right into the ventilation duct.

For some unpleasant and obvious reason, the toilet ventilation duct, though only a branch pipe, is wider than the usual pipe, and is directly connected to the main ventilation duct on the floor - thus ensuring that there is enough wind power to pump out some unpleasant smells......

Ye Chi hid the fence behind the trash can, grabbed the outer edge with both hands, and with the strength of his waist and abdomen, the whole person leaned into the pipe.

This pipe was already wide compared to a ventilation pipe, but it was still not enough to make Ye Chi turn his head, otherwise he would have been able to install the fence......

And if Ye Chi carried a slightly larger backpack, it would be quite difficult to move forward here.

Ye Chi is still in a relatively thin state, after all, he is still in the recovery period......

After a few minutes of crawling, he finally entered the main ventilation duct, and there was a feeling of sudden enlightenment.

This pipe is quite wide, although it is not high, but it can also make him crawl happily without worrying about hitting his head, and it is enough for two or three people to move side by side.

He used the compass on his watch to make his way and crawled towards the information center.

At the same time, he activated the relay station he had placed during the early reconnaissance.

"The command center, the communication base station has been activated, and the signal is tested."

"The signal is normal, the bandwidth is 4mBits, which is lower than expected, but it is enough."

"It's set to long standby mode, and the bandwidth should be reduced, which is normal, so move on."

"Yes, I'll alert you if the signal is attenuated."

"Understood."

Ye Chi calibrated his direction again and moved towards the information center.

From time to time, he passed through the vents of the ventilation ducts with lights shining in, and Ye Chi entered a branch pipe again.

This pipe is not much narrower than the main pipe, and this pipe is the ventilation pipe that directly connects to the most important facility on this floor, the information center.

He climbed to the opening of one of the brightest ventilation ducts and looked out through the gap in the fence.

Sure enough, it was the same hall he had been to.

Unlike when he went, it was even a little deserted, with only a few researchers running around several different consoles to record data, and now, almost every console has one or even a few people recording or manipulating it.

Each of them had a fanatical expression on their faces, as if they were fire thieves in the New World.

Is...... It's ugly......

is obviously doing heinous evil things, but he puts on a DIO appearance for the progress of mankind and world peace......

is obviously just a group of scum with no bottom line, but they look like they are in the dark and cultivating the light......

Ye Chi pulled out a metal cylinder from his waist bag - this was not some kind of lethal spy weapon, just a pair of hose speculums.

I pulled out a telephoto lens from another bag, connected the two things, and connected them to my phone to control the shooting through the app - this thing is quite down-to-earth.

Judging from the APP,This thing is not simple,It seems to be able to shoot4K video,The photos taken are even more 41 million pixels of high resolution-the resolution of the military-grade chip will definitely make the civilian version cry and faint next to the toilet,That is to say,This thing is far more DIO than most SLRs。

Ye Chi tried to manipulate the thing to poke out of the vent, and the matte black paint made it perfectly hidden in the shadow of the vent.

It is indeed quite a high resolution, and Ye Chi can even clearly see any word on their screen now.

Human Mental Tolerance Test

The number of samples is 499

Honkai number 137

The number of reconstructions is 137

……

Just as Ye Chi was shooting, the number of Honkai had increased by one, while the number of reconstructions remained the same.

In other words, a person has just had a mental breakdown - although theoretically this should be a virtual personality and will not lead to the collapse of his own personality, but ......

Still mad......

Is this something that a man can do?

Ye Chi could only endure it...... I couldn't hold back and killed them all.

He tried not to miss every detail, and the faces of those people - these people, none of them could escape.

"Enough...... The main goal is complete, and let's move on to the next goal. ”

Ye Dad's voice came from the headset, probably because the adapter was not bandwidth enough and was a little distorted.

"Understood, ready to go to the top floor."

Ye Chi whispered into the microphone.

"Now the plan is back, the original plan remains the same, enter the elevator shaft through the ventilation pipe, understand?"

"Understood." Ye Chi withdrew the speculum and slowly retreated.

The main ventilation system includes a series of ventilation structures in the building, including an elevator access tunnel.

"The access tunnel ventilation duct has been entered...... Plenty of space. ”

"Be careful, I haven't used it for a long time, there may be a lack of oxygen."

"Understood, I'll go down with an oxygen cylinder in my mouth."

A canister the size of an insecticide, containing enough oxygen for half an hour for the average person, attached to a mask-like face shield.

He put on his oxygen mask, opened the valve, kicked the fence, and entered the passage, small enough for two people to walk side by side.

And he was finally able to stand up straight......

Sure enough, there is a lack of oxygen, and you can feel the feeling of stuffiness in this winter.

Ye Chi slightly turned up the brightness of the cold light source, and along this passage, he moved towards the end, and at the same time left a "button" here

Forcefully open the pressurized door at the end, and a storm swept through the entire passage, taking away all the stuffiness.

"Sure enough...... Arrived at the elevator shaft. Ye Chi looked at the vast passageway, "It's like a highway."

Indeed, several non-stop elevator groups are like the busy traffic on the highway, and the space is far wider than expected.

Dense derricks and X-shaped steel frames with huge steel beams form the skeleton of this space, while on the other side of the elevator is quite a large space and a variety of encapsulated cables.

"Would you like to take a break? It's already lunch time, and the elevator activity is relatively dense during this time, but after this peak period, there should be a break for a while, maybe you can take a ride or something......"

"What you say makes sense...... Ye Chi couldn't complain, but yes, there were really not many places for him to sit there quietly and eat, most of the time he spent climbing and crawling, a rare opportunity to sit up or stand up - and not afraid of being discovered.

Is it a nutrient solution with a strange taste for lunch, or is it an apple flavor that you can't spit out...... But it's not unpalatable, plus a little energy bar.

Ye Chi couldn't help but be a little glad, if he really climbed the garbage chute all the way to the top as originally planned, he would now be unable to extricate himself from the lunch hell - tons of empty lunch boxes fell from the sky......

You're more drunk than in the morning......

Hurry up and solve the endless crawl after lunch......

Fortunately, the X-frame and steel beam of this side of the wall are very regular, but I don't worry about not being able to climb, but passing through the gap between the elevator and the elevator is still a little scary, after all, the cars on both sides are only about half a meter away from him, and it is quite scary when he passes by.

But it went so smoothly that he actually hitched a ride - as he climbed to the 40th floor or so, an elevator happened to pass by and stopped at his feet - and it looked like it was going to keep going......

Then he actually hitchhiked to the 52nd floor, only three floors away from the 55th floor where the target was.

With the support of equipment, this distance is only a matter of time.

Then he went into that circular passage, the cooling tunnel of the main engine room.

The warm air is being continuously drawn from the two exhaust fans, distributed into the elevator ducts, and continuously carried away by the air flow carried by the elevator and the top fan.

The design is indeed quite unique, but ......

In front of Ye Chi were two large fans with a diameter of more than one meter, which were spinning at high speed, and Ye Chi glanced at the steel blades - this is the rhythm of turning into minced meat......

But not at all.

Black technology is coming~

Ye Chi took out another shaped "button".

A little bigger than the one used as an interposer.

Then press the button in the middle and carefully hold it close to the fan's axle.

And then that little thing...... It was directly attached to the axle.

Then it was visible to the naked eye that the fan slowed down, as if it had stopped in the next second, and there was already a trend to reverse in the next second......

Ye Chi took advantage of this opportunity to quickly drill through the gap in the impeller and pass through this pass.

In fact, there is nothing high-tech about that little thing, a battery, a microwave transmitter will do it...... Add up to one electromagnet.

This little thing is not powered off, on the contrary, he is powered.

As we all know, the civil voltage in Japan is 110V sinusoidal alternating current.

Through the principle of power supply, the peak current is staggered and the power transmission is reversed - even middle school students know that this will "neutralize" the current, thanks to 110V, if it is 220V, this cannot be done.

Ye Chi hurriedly turned off this little thing through the remote control, leaving only the electromagnet for adsorption - the little thing does not have much electricity, and it is like relying on a small prop and the entire national grid to resist is a brain-dead act.

This passage is unusually spacious, after all, there are two large exhaust fans with a diameter of 1 meter at the end, so the inside of the duct is also very spacious.

However, since there is a guy behind him who can grind him into minced meat, he still uses the same method as when climbing vertically, that is, using an electromagnetic patch to fix it as his safety rope.

The fence was removed and put into the pipe, and Ye Chi hung upside down like a bat from the inside.

It's a pretty sci-fi space, with cabinet-like glass-encapsulated server units as far as the eye can see, and steel panels covering the floor, walls, and ceiling - it feels like you're in a five-cent special effects movie at all times.

In fact, this is just for electromagnetic shielding, simple and crude, and the effect is remarkable.

Ye Chi pasted his whole person on the ceiling, the all-steel ceiling gave him great convenience, he could easily move himself on the ceiling as long as he used the electromagnetic patch, like a gecko......

There is a CCTV surveillance camera that locks the view directly to the console.

Since it was a closed circuit, there was no way to interfere easily, and it directly locked the operating table, which really hit Ye Chi's death hole.

He felt through the ceiling just to avoid the camera.

That's the only difficulty with this step, because there's even one guard at the door, and that security guard ...... Easily won't come in......

It seemed to them that this place did not need to be guarded at all......

While these instruments are expensive, there is no chance of damage other than natural wear and tear...... As for someone sneaking in? Is this just a private business, or is it running a game, how can anyone destroy it? Even if someone can't think about it...... He can't get in either......

In their opinion, as long as they can't get in through the main entrance, they can't get through.

Pattern Diagram Milk Dance.

Approaching the camera from the back, Ye Chi used a knife to cut open the outer skins of the two exposed wires, took out two electrode clips from his waist bag, and directly short-circuited this thing - such a simple and crude approach is actually very safe, because those two electrodes are connected to a very mature instrument, and some small things that everyone knows about the miraculous feats of Black Ops...... As long as you are wired, even if it is a military standard, you have to kneel, not to mention you as a civilian electrical appliance......

Now the monitoring center should be playing the image more than ten seconds ago, as long as no one comes in, he can't find it, and the wire skin is only a small hole, not to mention that they can't think of checking it at all, even if they check it, they can't find anything.

Then Ye Chi can swagger and do his own thing.

Pull out the self-reading and writing hard disk that I carried all the way from the backpack behind my back, cut out the USB cable on the side, and plug it directly into the console.

Then this brute-force instrument doesn't even need to be opened on the bar console, and directly starts to forcibly read and write hard disk data.

All Ye Chi had to do was look at the wind.

In less than 20 minutes, all the data has been copied.

Put away the instrument, clean up the traces you left behind, and go back the way you came.

"Mission accomplished, ready to evacuate." Ye Chi stood in the gondola of the cleaning elevator and said into the microphone.

No one will notice that a van appears like him and merges into the traffic of Tokyo like a ghost.

――――――――――――――――――――――――――――――

I'm back again!!!

Finally had a bite to talk about during the winter vacation!!

You can code words happily!!

There is no DDL anymore!!

In addition, this volume is almost over......

A large part of this volume about technology is my own speculation, after all, I'm not one of those great gods who can really write a reasonable secret sneak in, and I don't have that much information to refer to, so everyone should laugh at it.
