The strongest reserve for the doomsday

The Taoist thought about it, Alice's words are not unreasonable, it's not good here, there are really a lot of the latest high-tech mutant creatures infested.

"Alright, let's get to work!"

The Taoist didn't talk much nonsense, because this backup circuit was about to start, and it would be exposed if it didn't work out at that time.

He hurried over to the control panel that Alice was pointing to.

The control mechanism of this gate does not belong to the sixth layer, but to the seventh layer, so the power outage on the sixth layer has nothing to do with the seventh layer.

There is still electricity here, and I saw that the screen above showed a sign of a palm.

"Palm print recognition?"

The Taoist carefully looked at the English instructions inside, and indeed, the first password was palm print recognition.

Of course, on this side, there is still a password to enter, but now the Taoist has no time to study the password, so he directly breaks it and dismantles this control panel directly.

Because these industrial-style circuit designs are very rough, the Taoist directly dismantled the control panel, and there was nothing abnormal about this gate.

At this time, Wang Ying had already found a good position, dragging his cheeks on the side and looking at the Dao Chief, thinking about what means the Dao Chief was going to use to crack this door.

That's right, the little girl is not interested in technology, but in the boys and men who crack the technology, especially the men who work hard, are simply irresistible. If they can repair computers and reinstall systems, then in their hearts, they are no different from Superman!

The chief dismantled the empty panel, and below it was the circuit board with various plug-ins.

The Taoist took a flashlight and wrote on the side of these circuit boards:

"Schneider M340 PLC microcontroller."

The Taoist chief secretly sighed:

"It's true, it's not a family, don't enter a family!"

At this time, Wang Ying heard it on the side, thinking that there was a play, so he asked a little excitedly:

"Dao Chief, have you found a way to crack it?"

The Taoist nodded and said, "

There is a PLC laboratory sponsored by Schneider in our university, and when Lao Tzu was in college, he happened to have programmed this PLC and ate this system all over the place." The PLC of this signal has 108 IO ports, of which 56 are mirror backups of each other, to put it simply, if one of the IO ports says that the output is 1, then the backup point opposite him is 0.

Wang Ying was on the side, waiting to look at the Taoist with big eyes, the Taoist took a look, Wang Ying had a hen (I don't know) expression, and the Taoist sighed and said:

"It's really playing the piano to the cow!"

After Wang Ying listened, the two ponytails were cocked

, and the sound of "bang~"

took off on the spot, and jumped up to grow a sweet chestnut.

Fortunately, the Taoist dodged in time, and then hurriedly explained:

"The opposite means that I unplugged all the IO ports above and plugged them into the IO ports below. In this way, what really becomes wrong, and what is wrong becomes right! When the time comes, I will reinstall the control panel above, so that as long as I enter a wrong password, the wrong password will be considered the correct signal by the PLC, so that I can open the door without much effort. Hahahaha~Haha~"

The matter hasn't been done yet, and the Taoist chief is already laughing on the side.

Alice hurriedly knocked on the side to pull the chief back, and said,

"Hurry up, there are still 3,40 seconds left!"

"Hmm!"

After the Taoist finished speaking, he hurriedly installed the control panel, but after installing it, he found that there were a few more capacitors in his hand?

The Taoist chief stiffened his head and threw these capacitors aside, thinking that the machine should be fine with a few fewer parts!

After installation, fortunately, the machine was officially started, but it showed the boot interface of Windows,

"Damn! What about cryptosystems? Lao Tzu just changed the IO port, but there is no reinstallation system! No way! But it doesn't matter, the control system of this gate is also a program, and the windows system behind it is a lower-level system, cracked to this level, and then write a script program, directly control the IO port output, you can directly control the gate!

Just as the Taoist chief was about to find a USB port and plug in his USB flash drive with the virus, Wang Ying, who was on the side, watched the Taoist chief busy in front of him for a while, suddenly walked over, and said softly:

"Dao Chief, are we going down to the 7th basement?"

The Taoist replied casually:

"Nonsense, Lao Tzu is working on a cracking program, Xiao Po Zi is staying aside, don't affect Lao Tzu's thoughts!" It's too late!

After saying that, the chief continued to sweat profusely and plugged wires into the power strips, all kinds of sockets, ready to physically inject the virus.

Let the Taoist chief break out in a cold sweat, and his eyes are full of gold stars.

"Why do you want to go down from here, you can go straight down from the ventilation duct on the west side."

"Each layer of the ventilation duct is equipped with a thick protective wall, and Lao Tzu has not seen it!"

Although the Taoist chief really hasn't been there, UBM has really seen it, of course, from the surveillance camera.

Wang Ying returned a little anxiously:

"Where is it, oh, there is a crack, just go through it." But there's nothing fun going on underneath this, and there are quite a few monsters inside!

"Play with your head! Lao Tzu is going down to do the right thing to save people! Huh? What did you say? Have you ever been down? Dao

Chang was like a drowning man, grabbed a straw, hurriedly turned around, grabbed Wang Ying and asked. But Wang Ying's next sentence made the Taoist chief stunned.

I saw Wang Ying return a little helplessly:

"I often come down here."

"What, you come down often, what are you doing here?"

"Come down and find something to eat!"

Wang Ying returned directly.

At this time, the Taoist chief glanced at Alice, who spread her hands and said that she didn't know.

"Well, that's up to you!"

The Taoist chief replied casually, but in a blink of an eye, he felt that something was wrong, and hurriedly said

, "Damn, you didn't say it earlier." Hurt Lao Tzu to tinker over there for a long time.

"Did you ask me, and besides, Daoist, didn't you say that I can't talk casually without your consent?" That's why I thought you were here to study circuit technology and fix computers! The

Taoist almost fainted, and hurriedly explained:

"Lao Tzu is not here to study circuits and repair computers!"

But after thinking about it, this is really the study of circuits, but not this kind of security circuit, but the line of the super artificial system and the outside world, or the network.
