Summer in southern Chongqing is painful, and most of the people who work outside rarely go out because it is too hot.

Now that the problem of the campus platform has also been opened, Yu Xue was arranged by Wu Yunchang to manage the 'food delivery staff' of the business school.

Recently, there have been ways to seek cooperation in the confession wall messages of various campuses.

Mostly some institutions.

For example, driving schools, graduate school entrance examination institutions, and some gyms and barber shops advertise cooperation applications.

As the traffic grows larger, and there is no need for publicity, someone will come to the door to cooperate.

Jiang Chengwen is also paying attention to the information sent by these cooperations.

However, he didn't let Wu Yunchang take care of these, but left it alone, Jiang Chengwen wanted to take care of all this cooperation after the start of school.

"After school starts......

Wu Yunchang thought for a moment and said, "In this case, will it be crowded together?" ”

"No, it won't." Jiang Chengwen said: "Divide the time to break, it is enough to receive five advertisements a month, and if you don't receive more, send them separately, don't get together." ”

"But Mr. Jiang, it is estimated that there will be a lot less income in this way."

"Simple hunger marketing, I don't need to say more."

"Is that so?"

Wu Yunchang thought to himself that what Mr. Jiang said was right, and hunger marketing might have a big effect.

"In addition, I won't accept all promotions, for example, some gyms, some of them change their bosses every year, and they change one shot at another, so it's not necessary."

"Understood, I'll take a closer look."

"Well, I'm doing a lot of work on my side of the app, test it tomorrow, if it's no problem, you can also prepare to go online, and I'll have to trouble you to run when the time comes."

"What Mr. Jiang is saying, this is my business."

"I've worked hard for you this time."

"It's not hard."

"I'll give you a vacation and have a good rest."

After hanging up the phone, Jiang Chengwen devoted himself to the code code.

I wrote until the afternoon, and the debugging was complete.

After encapsulation, I ran it on the emulator again, and the effect was okay, no stuttering, and no bugs.

The rest of the tests are waiting for tomorrow and require data from a server connection to get the final results.

"It's finally done."

Jiang Chengwen took a sip of water.

He got up and walked outside, but he didn't see Han Jingren at home.

"Where did you run again?" Jiang Chengwen thought for a while, took out his mobile phone and made a call.

After connecting it, Han Jing's voice was a little noisy, and Jiang Chengwen had a headache when he heard it.

"What are you doing over there? So noisy? ”

Han Jing glanced at the workers behind her who were sorting out the goods, and she lied and replied: "I'm buying vegetables, there are a lot of people, I'll be back in a while." ”

"Grocery shopping?"

Jiang Chengwen was happy in his heart, but he didn't demolish Han Jing, but said, "Come back early." ”

"Okay, hang up the dog first, don't say anything."

Han Jing hung up the phone.

She let out a long sigh of relief, then looked at the blueprint in front of her.

Her technique is a little rusty, but the final picture is particularly accurate.

The computer shows a blueprint of a shirt.

With that done, she got up and walked to the small warehouse behind her.

The conductor said: "These clothes are divided and placed on different shelves, so that they can be distinguished. ”

"Okay boss."

"Well, I'm sorry for you."

Han Jing picked up the bag on the table, and said to the person in the other position: "I'll go out for a while, you can check the goods at the warehouse, and if there is no problem, you will sign for it." ”

"Okay, Sister Han, go ahead."

"Well, good job."

After Han Jing went out, she took a taxi and went straight to the vegetable market, and after arriving at the place, she bought some vegetables casually and went home.

After taking out the key and opening the door.

saw Jiang Chengwen sitting on the sofa and watching TV.

Han Jing took a breath, calmed down, and then walked over with a smile on his face and said, "I bought plum cabbage button meat today!" ”

"Really?" Jiang Chengwen said with a smile: "You said that you are not tired every day, isn't it the same when you turn around and let me go." ”

"You?" After Han Jing sat down, he stroked his hair and said, "I'm a professional in grocery shopping, you can't do it." ”

“……”

Jiang Chengwen found that he couldn't seem to refute it.

Han Jing smiled and said, "Besides, I have to take care of you and raise you to be fat and fat, healthy and safe." ”

Jiang Chengwen was stunned when he heard this.

Then he smiled and nodded.

In fact, speaking of which, this girl is still very scared in her heart, and she always puts the words peace and security on her lips.

Jiang Chengwen smiled kindly: "Don't worry, I won't get sick, and nothing will happen." ”

Han Jing nodded, stretched out his hand, and touched Jiang Chengwen's head.

"Good."

Jiang Chengwen wanted to reach out and shoot her off, but after thinking about it, he forgot it.

Let her be fine once.

After that, the two of them cooked together, Jiang Chengwen was in charge, and Han Jing was on the side.

The meal was very peaceful and warm.

Han Jing sometimes looked at him and smirked, not because she was stupid, probably because this plainness and warmth were not easy to come by, so she would cherish it very much.

In the evening.

Jiang Chengwen went into the bedroom again and sat down next to the computer.

And Han Jing had nothing to do, so she moved a chair and sat next to Jiang Chengwen.

While replying to messages, she would glance at the contents of Jiang Chengwen's computer screen from time to time.

"Huh?"

Han Jing saw Jiang Chengwen open a web page, which read.

【Huaxia Red Guest Alliance Forum】

And the next operation made Han Jing a little incomprehensible.

A bunch of gibberish.

"What is this doing?" Han Jing asked.

Jiang Chengwen said: "If you want to register for this forum, you have to do questions, sometimes the questions are clearly indicated to you, sometimes they are hidden in the source code or somewhere, only after finding and answering these questions, can you become a member of this website." ”

This is a game.,Only if you're qualified can you become a member.,But the difficulty of this nested puzzle at the time of registration is not high.,As long as you know a little bit about it.,Basically, you can do it.。

After successfully registering, Jiang Chengwen entered the backstage.

He started looking at the forum's security, trying to find a vulnerability somewhere.

I missed the IP of the website and the information of the server again, and after searching the directory, I wanted to find the background address of the forum from it, but the result was not ideal, and I didn't find anything.

There must be a backstage, but I don't know where it's hidden.

"Is it an IP designation?"

Jiang Chengwen felt that such a possibility was very large, so the possibility of going deep in the background was very small, so he began to try other ideas.

Jiang Chengwen didn't even bother to try this way of database injection, but it was the Red Guest Alliance, if this security was not done well, it would not be the Red Guest Alliance.

Han Jing watched Jiang Chengwen's fingers twitch quickly on the keyboard.

She wasn't surprised by such a picture.

However, she was a little curious about what Jiang Chengwen was doing now.

"I said dog, you can't be doing something illegal." Han Jing asked.

"Not really."

Jiang Chengwen said: "I'm just trying. ”

"Try?" Han Jing paused for a moment and asked, "What to try?" ”

"Let's see if we can get into the backend of this website!"

Jiang Chengwen switched the page, and then he operated the instruction program and operated.

He fixed his eyes, but found countless honeypots, but these false things were seen through by Jiang Chengwen at a glance.

He bypassed all the honeypots, silently broke open the port, and went straight into the backstage.

"Got in."

Jiang Chengwen's face was calm and said: "Sure enough, it is an independent backstage, which restricts the IP. ”

"Huh?"

Han Jing was stunned for a moment and continued to stare at Jiang Chengwen's operation.

Although she couldn't understand it, she was just a little worried.

Jiang Chengwen glanced at the connection database.

It was found that there were five first-level accounts with parallel permissions.

In other words, there are five managers of this forum.

At the same time, Jiang Chengwen also took a look at the responsibilities of these five IDs in the forum, two of them are moderators, and the others have nothing, presumably responsible for website maintenance.

Jiang Chengwen thought for a moment.

He left a secret door inside the website so that he could log in to the backend at any time.

Then he left a line of code in the database.

After that, the log files were deleted, except for the one that had been changed to the database.

After erasing the traces, Jiang Chengwen withdrew from the background.

"Good fellows."

Jiang Chengwen left the keyboard with both hands and glanced at the command window on the side.

See above character flashing.

"Only now? I've wiped all my traces clean. ”

Jiang Chengwen smiled, and then turned off all programs.

Han Jing couldn't understand anything, and asked, "What did you do just now?" ”

"I had a friendly exchange with the staff of this website." Jiang Chengwen replied.

"Why don't I believe it?"

"Really, it's communication."

Han Jinghu looked at him suspiciously and asked, "Really?" ”

"Or else."

……

The other side.

In a workshop.

A middle-aged man with a scruffy beard was staring at a computer, his eyes a little dark, caused by staring at the computer for a long time.

He had a cigarette in his mouth, and cigarette ash flying everywhere on the table.

"Bang Bang Bang ......"

He typed the keyboard extremely fast, but his brow was tightly furrowed.

The next moment, he stopped what he was doing.

"Ran away?"

He was stunned for a moment, and said to himself, "Can you run under my hands?" ”

"!"

He cursed and hammered the table.

Then he calmed down and immediately began to check the backstage, in case something important went wrong, the others were not to laugh at him half dead.

He doesn't want to be ridiculed!

After searching for a long time, he finally found a backdoor in the background, and also found the new operation of the database in the log.

"So arrogant!? The back door is so open!? ”

"You can't be a rookie, right?"

Then, he still looked up the traces, no matter what way he used, but he couldn't find this person's IP, only the secret door that he could easily see and the new operation of the database.

"Not like a rookie ......"

He frowned, then opened the database and looked at the new addition.

Inside are a few lines of code.

He glanced away, but paused.

The content of the code is a question, a question about network security instructions.

"Click, click, click......"

"Hoo ......"

He exhaled a puff of smoke, but a look of excitement appeared on his face.

He probably knew what the person who invaded the backstage meant.

Then, he picked up the computer and entered the virtual chat room on the network segment.

The people in the chat room are all online.

【[yezi]Join chat】

fk：【yezi？ Aren't you on duty today? Could it be that there are not many rookies today? 】

The website of the Red Guest Alliance suffers several or even dozens of attacks almost every hour, although the security of the website is very good, but it is also afraid of accidents.

Secondly, they usually like to play with these rookies who attack websites, and after catching the IP, they directly hang up on the forum and publicly execute them.

Yezi: [There's an old bird in the background, I didn't catch it.] 】

fk：【？？？ 】

With just one sentence, all the people who dived in the chat room were blown out.

Sword: [Is there a big problem?] 】

Three Lights: [Coconut, you're too vegetable.] 】

Apple: [I'll take a look.] 】

Yezi: [The man didn't do anything, I checked it, he left a secret door, and then he left a question in the database, and even kept the log, deliberately telling us that he changed this place, which is quite interesting, it seems to be testing us. 】

FK: [I read it, this question is a bit weird.] 】

Sword: [Yezi, did you catch him?] 】

Yezi: [No, I was chasing a rookie at the time, so I didn't pay much attention and let him run away.] 】

Three lights: [Coconut, you real dish.] 】

Yezi: [You tell me to put out all three fires for you.] 】

Apple: [That's an interesting question.] 】

Three Lights: [Really?] I'll take a look. 】

Yezi, who was sitting in front of the computer, looked at the contents of the chat room, and he continued to type.

Yezi: [This person has something, and the traces are all deleted very cleanly, but he hasn't changed anything, and he hasn't had any impact on the website. 】

FK: [You think he's here to exchange technology?] 】

Yezi: [I don't know, what do you think, should this secret door be kept.] 】

Three Lights: [Why are you keeping it?] What if it's a pit. 】

FK: [What the lamp said is true, although this person didn't show aggression this time, but I'm afraid it's an illusion.] 】

Yezi: [Okay, then I'll go through the secret door.] 】

FK: [From which port did he come in?] 】

yezi：【923】

FK: [Okay, I'll take a look.] 】

Apple: [You talk, I went to solve the problem, and the question left by this person is quite difficult.] 】

Yezi looked at the content posted by Apple, and then he also went to look at the title.

"Is it that hard?"

After he looked at it carefully, he paused suddenly.

Then, he began to immerse himself in solving the problem.

However......

A night passed.

But he still hasn't solved the problem.

When I looked up, I found that it was already dark.

“……”

Yezi lit a cigarette and went to the chat room to ask.

Yezi: [Have you figured it out?] 】

However, there was no reply.

Not only him, but the other four were also in the process of solving the problem, and they didn't even read the information in the chat room.
