ADAPTED FROM JINJIANG LITERATURE CITY NOVELS

WRITTEN BY TWENTINE (ZHOU AIHUA)

Thank you so much.

It's nothing.

I've added a lot of contacts.

Come on.

I specially ordered these crisp pastries.

They taste so good.

They are quite famous in Shanghai.

Come and have a taste.

Everyone, come on.

Take it.

Pass them around.

Come here.

Is it tasty?

How does it taste?

-It tastes good. -Good, right?

I think this restaurant is nice.

There's one more portion.

Take it.

Thank you.

Have a taste.

It tastes good.

It tastes very good.

I qualified for the finals, Li Xun.

Thank you very much for your help.

-Thank you. -Not at all.

Thank you for giving me advice.

I really appreciate it.

It's no big deal.

Are you Zhu Yun?

I heard from Gao that

you're also a main member of the Nanhu University Base.

May I have your phone number?

Here.

A few days ago,

Gao showed me the source codes

of your Blue Crown app.

The source code is concise and accurate.

It's a pity that

you are not taking part in this competition.

But then there are also some issues with this competition.

What do you mean?

Some contestants

have managed to win by devious means,

greatly shocking us.

Do you mean our senior?

He's the shame of our university's School of Information Technology.

There's a rumor on campus that

his tutor and sponsor once cooperated.

Knowing they set up a new studio recently,

his tutor and sponsor received several topics in advance.

When it was almost ready,

they invited some students to do the tail-in work.

They can make a profit from patent sales

and also win prizes.

They reap the benefits at both ends.

Let's welcome Fang Zhijing, the winner of the Special Attention Award

to come onto the stage

and press the crystal ball with us.

Was he that student

we saw on stage?

Yes.

That's him,

Fang Zhijing.

Who are you talking about?

Xu Lina.

Why didn't you invite me to dinner?

You seemed too busy to have dinner with us.

Zhu Yun.

It's really you.

I remember you go to Nanhu University.

Well, you should have told me

you were coming here,

so that I could do the honors.

Don't you

recognize me?

It's me, Fang Zhijing.

It has been a while, Fang Zhijing.

Are you also here for the competition?

I didn't see your name on the list.

Were you eliminated?

It's funny.

She could design the Blue Crown app,

let alone the finals.

You must be Li Xun.

Hello. I've heard a lot about you.

I'm Fang Zhijing.

Your Blue Crown app

turned out to be a success,

but it's buggy every now and then.

It would be better if it could run smoothly.

It doesn't matter.

You are a freshman,

so it's normal to have some weaknesses.

Yes, it's normal.

Its DAUs are ten times more than expected.

We still need to upgrade the server.

It's a pity that

we can't fight it out

in the competition this time.

Well,

enjoy yourselves.

By the way, Zhu Yun.

Please tell me in advance

before coming here next time.

An arrogant guy like that

will cause his own downfall sooner or later.

Yes, I'm here.

Just go upstairs.

Okay, bye.

Well, Zhu Yun,

did you need anything?

If there's nothing, I'll leave first.

See you around.

Do you still remember Xiaoyan?

Of course.

I visited her grave during the Lunar New Year.

She has been gone for so long.

I wish her well in heaven.

Honey, I'm here.

Let me introduce you.

This is my old classmate, Zhu Yun.

This is my girlfriend, Wu Yuxin.

Hello, Zhu Yun.

Let's go have dinner.

Your teacher is waiting for you.

Don't worry.

The competition is a mere formality,

let alone the forum.

What do you mean by that?

I'm not interested

in the forum,

but our project team has cooperated

with the sponsor of this competition.

So they invited me to the launch ceremony.

Let's go.

I'm just here

to be the first-prize winner.

All right. That's enough.

See you, Zhu Yun.

You told her too much.

Don't worry.

She can do nothing to me.

What would you like to eat today?

Zhu Yun.

Where did you go off to?

What's the matter?

Let's go.

Zhu Yun, we are leaving.

Speak.

Let's join the competition.

It's a piece of cake for you.

As long as you take it a little seriously,

you can win as easily as winking.

Why should I waste my time

doing something pointless?

Li Xun.

Let's join the competition.

Why have you changed your mind?

I just want to take part in it.

Tell me why.

Tell me why.

Won't you join it?

No, I won't.

Are you also fed up with him?

Don't laugh at me.

I'm not.

But it's normal.

Ordinary girls can't stay with him for long.

Well, it is quite normal.

Why?

Li Xun has his own plans for everything.

Let me tell you.

I asked for his help

to design music synthesis software.

He was not available for a month.

Later, I offered to pay him

and he immediately agreed to do it.

He wants to start his own company.

He's prone to suspicion,

so he doesn't accept investment easily.

He wants to save money to start his company by himself.

Well,

why do you want to join the competition?

I just don't want that bastard to win.

I can't let him win first prize.

Who?

Fang Zhijing.

-My best friend in high school -Happy birthday

-was Liu Xiaoyan. -to you

-Happy birthday -In her junior year,

-Xiaoyan was very close to a senior. -to you

-She only told me about it. -Happy birthday to you

VANILLA

It's melting.

Why don't you put it in the freezer and take it out later?

No one will steal it.

No.

What if someone else takes it?

He loves vanilla ice cream best.

You keep talking about him.

But who is he?

I'm here.

This is for you.

Vanilla ice cream? Thank you.

I haven't finished my homework. I'll leave first.

-Bye. -Bye.

It's the last one.

It was hard for me to get it.

I told you it's better if we kept this a secret.

It was also on that day that

Liu Xiaoyan and Fang Zhijing's secret relationship

was exposed on the school forum.

THE PUPPY LOVE OF A SENIOR IS EXPOSED

COME AND HAVE A LOOK!

What's up?

Someone posted it to the school forum.

THE PUPPY LOVE OF A SENIOR IS EXPOSED COME AND HAVE A LOOK!

I got it.

The IP address happens to be our school computer room.

So someone at school did it.

What a busybody.

Well, we can say

we happened to go home together.

My bike was broken, so--

Our teachers won't believe that!

Right now is a critical time

for the selection of the provincial merit student.

If it weren't for you,

this wouldn't be such a mess.

Fang Zhijing had been elected as the provincial merit student

for two consecutive years.

If he was elected thrice,

he would secure a place at Information Technology University.

But Fang Zhijing was criticized at school

because of the photo.

To protect his guaranteed acceptance,

Fang Zhijing released his chat messages

with Xiaoyan out of context

and shifted all the responsibilities onto Xiaoyan,

making her the target of public criticism.

MORE DETAILS! MORE DISCLOSURE!

She's so shameless!

That's her.

As good as she looks, she's such a nuisance.

Stop pretending.

Xiaoyan.

Why would you post your messages with Xiaoyan

but purposely remove

unfavorable information?

Did you see me do it?

And it's none of your business.

But it's not the truth.

It's you who pestered Xiaoyan.

Pester?

Did I pester her?

Xiaoyan is so kind to you, but you hurt her ruthlessly.

If so,

why can't she sacrifice for me?

Xiaoyan is very sad now.

Go and see her.

Meeting her is inappropriate now.

If others find out that we are still meeting up,

I can't deny what happened.

Then her sacrifice will become meaningless.

Then at least comfort her.

I said I have no relationship with her.

Don't bother me again.

Fang Zhijing.

Fang Zhijing actually made a statement.

Fang Zhijing rejected her,

but she still pestered him shamelessly.

Xiaoyan seemed to live in darkness since that day.

Fang Zhijing was still a good student in everyone's eyes.

Xiaoyan became quiet

until one day…

Zhu Yun, something bad happened!

Liu Xiaoyan took sleeping pills.

How is she?

I don't know. She's still in there.

Liu Xiaoyan's family member?

-I'm not. -I'm her mother.

The patient's central nervous system

was inhibited by a large number of sleeping pills.

Because of prolonged brain hypoxia,

she has been declared brain-dead.

Resuscitation is of no use.

How could this happen?

-Ma'am. -Ma'am.

-Ma'am. -Xiaoyan.

NURSE STATION

Xiaoyan!

Xiaoyan.

My girl.

Fang Zhijing!

My baby.

My girl!

What do you want me to do?

Shame on you.

You know Xiaoyan is a shy person.

Even when the other students laughed at her,

she still cared about your feelings.

But you confused right from wrong

and humiliated her

to guarantee and secure your spot.

Don't you have a conscience?

I didn't ask her to take the sleeping pills.

She had psychological problems.

Am I to blame?

As soon as I heard about her accident,

I rushed here.

I've done my utmost.

She killed herself because of you.

-You killed her-- -Zhu Yun!

It had nothing to do with me.

You cannot say that.

The bad guys in the fairy tale world

would never come to a good end.

But we don't live in the fairy tale world.

The bad guy enjoys a good life

with excellent grades and a loving relationship.

He feels as if nothing had happened.

He has no sense of guilt.

Why?

A bad thing

never dies.

The result proves everything.

I cannot let him stand on the podium.

Never.

Why have you come here so suddenly?

It seems serious.

Gao,

I want to join the information security competition.

Sure.

But you said…

I've changed my mind.

Okay.

The contestants are in groups.

To be honest, I was a little unsure about it.

I thought about finding helpers.

Do I need to register?

No, I can add your name directly.

I'll send you the project progress later.

Okay.

Zhu Yun,

why do you want to join so suddenly?

I want to win first place.

Good.

I'm meeting Old Lin.

Let's go together.

Let's go.

CPU UTILIZATION, SYSTEM INFORMATION, NUMBER OF APR ATTACKS, APR INTERCEPTED

Look,

you've done a good job.

Keep calm.

Do you think it can stand the test?

Yes, sure.

This is the printed list of the finalists from various universities.

Have a look.

Mr. Lin, you've already gone through it.

Please give us your analysis.

I don't have much to say.

Only some common universities

and national defense universities

have real strength in the computer science major.

I don't have much to remind you of.

Just remember,

it depends on your real strength.

Read it yourself.

There's a strong group at the Information Technology University.

Their project is practical.

It's predicted that they will win a prize

and even profit from patent sales.

Is it Fang Zhijing?

What's their competition topic?

Mr. Lin, it's time for your meeting.

Okay, I'm coming.

Don't forget to close the door when you leave.

LIST OF THE FINALISTS, INFORMATION TECHNOLOGY UNIVERSITY

"USB Smart Encryption Interface."

Is his competition topic

"USB Smart Encryption Interface"?

That sounds quite practical.

If he wins

and applies for a patent, enterprises will be eager to buy it.

What's the matter?

Don't worry.

Our project is not bad.

If we do it carefully, it is also competitive.

Gao,

let's get Li Xun to join us, okay?

Why are you bringing him up?

He isn't interested.

I'll go and talk with him again.

The two of us can also make it.

You also want the first prize, right?

With him, we can win it for sure.

Are you so unsure of yourself?

No, but the finals are drawing near.

Or are you unsure of me?

That's not what I meant.

Whatever.

Go and ask him yourself.

STUDY EXTENSIVELY, PRACTICE EARNESTLY, SEEK IMPROVEMENT CONSTANTLY

But don't forget

to defend the ARP spoofing attack.

Such an attack is always disguised as a gateway

or a host in the network.

So you need to deploy

some monitoring points in the network

to monitor the false ARP data packets.

Find the ARP attack source

according to the false MAC

in the false ARP data

and only then, deal with the attack source.

INTERCEPTION FAILED

INTERCEPTION SUCCEEDED

INTERCEPTION SUCCEEDED

INTERCEPTION FAILED

We can't resist the flooding attacks at all.

If the attack source is slightly disguised,

it can bypass our defense system.

I'll try again.

I'm going outside to get some air.

Can you design

an encryption interface for the USB device?

What?

Can you design

an encryption interface for the USB device?

We work together every day.

What are you thinking about?

I'm serious. Can you design it?

If the encryption interface

is only made for functions,

we can find a single-chip computer as the main processor

and equip it with some interface chips.

Hardware isn't my forte,

so it may take some time to design it.

It's easy to design the software

as I just need to deal with the interface firmware

and key management.

Is it of high difficulty?

Why are you asking?

Your Highness, are you getting an outsourced project for us?

You've improved.

You know how to find work for yourself.

I have to remind you.

Don't serve them at a low price.

Charge high for it.

How long will it take you to finish it?

It depends on the offer.

What if you are very satisfied with the offer?

Then it depends on the requirements.

I have insanely high requirements.

In this world, there are various kinds and degrees

of encryption methods.

Advanced encryption is a process of continuous improvements.

But it won't take long

if it's only to realize the functions

of the encryption interface.

What's up?

These are common sense questions.

Why are you asking me?

100,000 yuan.

It's not enough.

That is just the deposit.

He's bursting with joy.

I know how much money you have.

Your Highness.

I don't think your card even have

one-tenth of the deposit.

How can you pay me?

Which is why I said it's the deposit.

Let me calculate.

I'll try to transfer 2,000 yuan

to the bank account every month

to pay for the rest of the money.

Which means I can pay you

10,000 yuan in 5 months

and 100,000 yuan in 50 months.

After that, you can collect the money.

What do you think?

Fifty months?

It's so long.

Are you paying me 100,000 yuan

for the USB encryption?

No.

This is for a different project.

Everyone thinks he will win.

Join the competition with me

to beat this project.

As long as you sign, we can make a deal.

After I pay you the deposit,

you can still keep my payroll card.

I will work for you for free,

okay?

Are you serious?

Yes.

PAYEE: LI XUN

INTERCEPTION SUCCEEDED

I did it.

I did it!

Everyone, I did it.

Zhu Yun, come here!

I finally did it.

I've done a lot of tests.

Both flooding and spoofing attacks

can be detected in real-time

and the ARP attack source can be automatically isolated,

which doesn't affect normal communication between hosts.

Well done, Gao.

Barring accidents,

I think we can at least win a prize this time.

We could also win the first prize.

Really?

Gao, let me in.

Copy the codes for me.

Why?

I didn't invite you.

This is my project.

Gao,

I told you I would invite him.

We didn't make any progress back then.

Now our project is almost completed.

Zhu Yun, why didn't you talk to me before deciding?

Let's talk outside.

He's a strong and excellent programmer,

but I don't need him.

What's going on?

Who launched the attack?

Let me check.

Don't bother.

Flooding attacks

generate a large number of false MAC addresses

in the network,

so you defend against them

by using the strategy

of configuring switch ports.

Spoofing attacks

will disguise themselves as gateways

or hosts in the network.

You choose to deploy some monitoring points

in the network

to detect false ARP data packets,

find out the ARP attack source

according to the false MAC

in the false ARP data

and finally,

deal with the attack source.

The idea is somewhat possible,

but you lack the necessary ability.

So this system

is full of loopholes,

from its architectural design

to the code level.

I broke through your defense system

with less than 20 lines of code.

I passed the preliminary.

The preliminary round is about concepts,

while the final stresses real strength.

After working night and day this month,

you designed such a shabby project.

Yet you want to win first place.

The judges will teach you a bitter lesson.

What do you want to do?

Help you win first prize.

I don't need you.

You can win,

but only if you listen to me.

Gao.

He is so arrogant

and unpredictable.

Mr. Lin,

if I take part in the finals by myself,

can I win?

Any contestant has the chance to win

or fail in a competition.

I mean,

you should not put too much pressure on yourself.

You are a freshman.

You have a lot of chances in the future.

There are all sorts of activities

you can take part in

every semester and every school year.

There are

regional, provincial,

and city-level activities.

You have many chances to train yourself.

So Mr. Lin,

I can't win

without his help,

right?

Jianhong,

you…

Let me tell you

about my own experience.

I was one of the first students

to learn this major in our country.

I remember the first time I got a computer.

I was so excited that

I couldn't fall asleep all night.

I came out top in the academic performance

in my class.

I was retained to work in our university after graduation.

My classmates envied me

and thought

I got the best chance.

Some of my classmates who weren't given satisfactory jobs

went off to Zhongguancun.

After a few years,

they became IT leaders.

If I compare myself to them right now,

whose chances were better?

Who won?

Who seized the better opportunities and resources?

Jianhong,

you have a long road ahead.

Don't let yourself

be trapped

by temporary wins and losses.

ARE YOU SURE YOU WANT TO PERMANENTLY DELETE THIS FOLDER?

YES

One day, I will let you know

I can be better

without his help.

3,437 ITEMS DELETING

Let's not waste time.

Let's talk about the amendments.

What's your opinion?

If it was up to me,

we should start afresh.

I don't think that's necessary.

Just reconstruct the codes with problems, okay?

We must rewrite it.

We are pressed for time.

Your program

is like a swimmer in cotton-padded clothes.

We can't find its bugs in the beginning,

but more will crop up as time goes on.

It will be too late by then.

I've deleted the previous program,

so let's rewrite it.

Okay.

Gao,

are you all right?

Yes.

Both of us want to win.

It's good that he can help us win, isn't it?

I've stayed up late for several days,

so I'm a bit tired.

I'm going back to rest.

You should rest early too.

Go back and sleep.

I have no time to sleep.

Li Xun,

be kind to Gao later.

Am I unkind to him?

He is still the project leader.

He's still the one presenting the project on stage.

Am I not kind enough to him?

What are you doing?

I'm putting up a bed for you.

Sleep on such a bed?

It's a bit like a farewell ceremony.

You may die from overwork

if you keep staying up late.

You stay up late more often than I do.

Don't compare yourself to me.

Come here.

Come here.

Sleep.

Why are you staring at me?

Close your eyes and sleep.

All the lights are on. How can I fall asleep?

Haven't you slept?

I'm making a plan.

Don't worry about me.

As we are pressed for time,

I should make a detailed plan

so that we can manage

every hour and every day effectively.

Li Xun,

you need to win.

You must win.

Don't worry.

You paid me, so I'll help you win.

You can ask me to do whatever you want

after the competition.

Write it down.

You said I could ask you to do anything I like.

Words alone are no proof.

Just put it down carefully.

But what you said is ambiguous.

You said it yourself.

"After the competition,

Li Xun can ask me to do anything he likes."

Zhu Yun.

Why are you returning this?

God knows how long I need to wait

before I can get your pay.

I just want this.

Li Xun.

I'm serious about this.

No matter what you want to do

and what goals you have,

you can count me in.

I'm not kidding.

I'll keep my word.

I know.

It's an insult to the fairness of the competition

that your shabby project can win a special prize.

It's all cut and dried.

You resorted to such dirty means.

You need to take responsibility for your remarks.

Then can you tell me

why you did this?

Because of love.
