Song, singing.

The crowd at the banquet was silent.

Anna listened to the song "I Just Love You", and the corners of her mouth rose slightly.

Chen Jiuqiang's piano voice is green and his singing voice is affectionate.

The end of the song.

He pondered for a while, then poured himself a glass of wine, got up and said, "What should be said has been said, what should be sung has been sung, it's all in the wine!"

With that, he did it and left the box.

Ye Kai asked him, "Why are you going?"

He lit a cigarette and said, "I want to be quiet." ”

After the second child left, Li Muzi got up and took the letter with the lyrics on it, looked at it, and then folded it carefully.

No one saw her move, except for Don't Chang'an.

After Chen Jiuqiang left, the girls of 602 were waiting for Anna to make a statement.

Anna was holding an empty wine glass, as if thinking about something.

Yu Ge whispered two words in her ear.

Anna glanced at her before getting up to leave.

After the two men left the box, they talked about something, and the others didn't know.

Afterwards, Don't Chang'an asked him, "How is it?"

Chen Jiuqiang smoked a cigarette and said lightly: "You can only understand, not speak." ”

……

……

……

The next day, when Bei Changan was in class, he received a text message from Li Muzi.

She asked, "You wrote that song, right?"

Don't Chang'an didn't deny it, he also knew that he couldn't hide it, so he responded to it in one bite.

"Well, yes"

"Haha, I think the handwriting looks like yours, but it's really nice. ”

Don't Chang'an looked at the text message, smiled bitterly in his heart, and didn't reply to her.

After a while, Li Muzi's text message came again.

"May I treat you to dinner? Just the two of us. ”

Don't Chang'an replied with two words: "No." ”

The topic ended, and the text messages didn't come again.

Looking at the screen, don't Chang'an think that the situation is not right, what is this woman going to do?

……

……

……

There are five days left, and it is Tang Wan's birthday.

On her first birthday, don't Chang'an want to give her something special, not to mention how unforgettable it is, but at least it must be commemorative.

In those days, a love letter, a guitar in one hand, and a bouquet of roses seemed to do the job.

But these are not what Don Chang'an wants, he feels that he should find another way and do something "big".

For example, imitate the "love story" of the hacker in the movie.

After having a plan, that night, Bei Chang'an invited Su Xiao to a restaurant outside the school, saying that he would invite him to dinner.

Su Xiao knew that Bei Chang'an must have something to say, so before the food came up, he opened his mouth first: "Third brother, do you have something to do with me?"

Bei Changan nodded and poured him a cup of tea.

"If you have something, just say it, I will definitely help if I can. ”

Bei Changan glanced at him, thought for a while, and then asked in a flat tone: "The school's power system, can you hack it?"

Before the words fell, Su Xiao, who was holding a sip of tea in his mouth, almost squirted, "What?!"

Don't Chang'an looked at him and didn't speak.

After a while, Su Xiao came back to his senses and asked him in a low voice, "What are you doing with that black thing?"

"It worked. ”

"What's it for?"

Don't Chang'an was a little annoyed by his question, "It's just useful, can you do it?"

"No, I can't. ”

"Is the technology not up to par, or what?"

Su Xiao was a little helpless, he said: "Technology is not up to par on the one hand, there are many, many problems. ”

"Tell me about it. ”

"First of all, the power system is not a public grid, and if you want to hack it, it can only be said that it works in theory, but if you want to turn it into reality, it is unlikely. ”

Don't Chang'an asked, "Why?"

"The power dispatching data network is a private network, and there is generally no physical connection to the ordinary Internet......

Don't Chang'an understood a little, "I just need to hack the school, is there a way?"

Su Xiao thought for a while and said, "I don't understand it either, but it shouldn't be much different from what I said." The same is true for the school's electronic control room, which is not a computer, but an integrated terminal, or a 'computer' similar to a monitoring center, which is actually just a terminal and cannot be operated by a computer. If you want to control the power supply remotely, someone must adjust the switch in the electric control room to remote control mode, and then let the host connect to the public network, and then modify the code level, which is a certain possibility. ”

"Can you do it?"

Su Xiao shook his head again and again: "I can't do it...... And ......"

"Say whatever you want. ”

"Moreover, if this is discovered by the school, it will definitely not be able to eat and walk around. ”

Don't Chang'an thought for a while and said, "Three thousand." ”

Su Xiao was stunned, waved his hand a little embarrassed, and said, "It's not about money, it's that I can't do it at all." ”

"Five thousand. ”

"Third brother, I'm really not sure. ”

"Ten thousand. ”

Su Xiao was a little shaken, looking left and right, but he hadn't made up his mind yet.

In the end, under the great temptation of money, he finally relented: "I can't do it alone, at least two people." ”

Don't Chang'an said, "Do you know any friends in this area?"

"I met one online. ”

"Is it reliable?"

"Reliable. ”

"That's good, I'll give you half first, and the other half will arrive as soon as it's done. ”

Su Xiao nodded, hesitated and said, "I can only promise you to try, and I can't guarantee that it will be successful." I can't get into the electric control room, and you can only figure out how to operate inside. ”

"I know a little bit about this, did I get the operation authority of the control room, and then adjust the switch inside to remote control mode?"

Su Xiao thought for a moment and added: "After adjusting to the remote control mode, you need to turn off the switch by commanding to achieve the purpose of power failure of the transformer, you can stop on one side or both sides." But as long as you turn off the switch, I can enter the intranet and control the transformer power outage, but one thing, in the whole operation process, once someone manually recovers, the previous efforts will be lost. ”

Bei Changan took a sip of tea and said, "It's okay, I'll figure it out." ”

……

……

……

The next day, early in the morning, I went to the school's fire center.

The electric control room is located in the fire center, a total of two floors.

The first floor is for electricity billing, and the second floor is the control room.

The person on duty in the control room today is a master in his fifties.

As soon as he entered the door, Bei Changan greeted him with a smile: "Master, hello." ”

The master glanced at him and asked, "What are you doing here?"

"Oh, I buy electricity. ”

"Buy electricity downstairs, this is not allowed to enter casually. ”

Don't look like he suddenly realized, nodded, and asked, "Downstairs, right? That, master, do you have a holiday on New Year's Day?"

"What's wrong?"

"No. 31, there's no one here, right?"

"Someone was on duty at night. ”

Don't Chang'an's heart sank, thanked him, and walked out of it.

Looking at the door of the control room, Don't Changan couldn't help but sigh, TM is a lie in the movie!

According to Su Xiao, in order to realize the computer-operated power supply of the entire building, the switch in the control room must be changed to remote control mode, and it cannot be restored.

If you can't get into the intranet, no matter how awesome the hacker is, you can't do anything.

In addition, the logical needs of the hardware need to be met.

Five defenses or something, a lot of logic is hardwired together with relays and other things, and if you don't meet the logic, you can't open it anyway.

What to do?

What to do?

Four days to go.

Don't Chang'an wants to give up, but he is unwilling.

That day, when Tang Wan told him about it, she looked very excited and yearning.

This surprise, don't Chang'an feel the need to fight for it.

But what to do?
