The world is in trouble

Chapter 249 The Hunt! The Choice! Life and Death
This bug is actually quite bizarre.

There was a player from a studio who was normally listing items for sale on the auction house. Then, for some reason, even though they only listed one item, it suddenly became 999.

He didn't know what was going on, but he immediately realized that this was a chance to make a lot of money.

So he started testing repeatedly, looking for opportunities to trigger the bug. Eventually, the professional hired by the studio owner found the principle behind the bug and wrote a script in the shortest possible time.

Initially, the studio simply copied the item and listed it on the auction house to earn gold coins.

However, they later realized that this method was too slow, so they started listing the item at the lowest price during the quietest hours of the night, when there were the fewest people online, and then flooding the auction house with it. They would then buy it themselves and resell it to item shops.

This is equivalent to unlimited money-making.

Then, they started selling large amounts of gold coins in gaming communities and on Taobao.

Thanks to their efforts, the price of gold coins in the entire game plummeted, and the studio made a fortune.

Of course, because online shopping was not yet developed at that time and Taobao was not very large, their behavior did not immediately arouse alarm.

In fact, on the third day, someone from the Perfect World development team discovered that the game's gold coin pricing system seemed to be collapsing rapidly.

Then, he and several colleagues immediately investigated and discovered the malicious bug that allowed them to duplicate coins, which gave them a fright.

Then, he immediately reported it to the person in charge, Li Qing.

His companion then said quietly, "Report it? Do you know what the result will be?"

He was immediately stunned.

Because the Perfect World team and Liao Feng have a certain degree of conflict and resistance, and Liao Feng is recruiting a large number of external teams to replace the original team.

Therefore, Liao Feng used the previous accidents as an opportunity to fire many people.

If this is reported again, another batch of people will be fired.

And doesn't our team bear any responsibility for this bug? We might even be fired.

"Don't report it. Just wait until the next server maintenance, and we'll work overtime overnight to fix this bug."

Immediately, all four members of the group nodded in agreement.

Thus, this serious bug had been discovered, yet no one reported it or fixed it.

If that were all, it wouldn't be anything special.

Next, the group suddenly had an idea.

Depend on!
The money is going to those studios; we'd be better off earning it ourselves.

Anyway, the servers will be down for maintenance next week to fix this bug, so there won't be many opportunities to make money.

So... there were four people in this group, and three of them secretly contacted their friends and their younger brothers to exploit this bug and farm a lot of gold coins on each server.

Then, sell gold coins through various channels.

Originally, only one studio was doing this, so the gold coin price system didn't collapse very quickly, and the studio leader knew how to make a fortune quietly.

The result is now...

Several malicious competitors have emerged.

As a result, the entire gold coin price system collapsed rapidly, leading to malicious competition and a stampede.

Moreover, more and more people are becoming aware of this serious bug.

A large number of players exploited this bug to duplicate massive amounts of gold coins, causing the entire game's pricing system to collapse.

By this time, the operations team had already discovered it.

But strangely, no one reported it.

Liao Feng, on the other hand, was always focused on the data of future generations. As long as the game's peak concurrent player count did not decline and continued to grow, he did not care about the game's ecosystem.

It wasn't until the sixth day of this serious bug that someone posted on the game's community forum, revealing the method for infinitely farming gold coins.

When the executives at Renren Games saw this, they broke out in a cold sweat.

Then, he tremblingly went to report to Liao Feng and Wu Lingxi.

By this time, more and more people were aware of this bug.

A huge number of players have already exploited this bug to farm gold coins.

"Server down, server down..."

"Fix the bugs..." Liao Feng roared.

Li Qing: "President Liao, perhaps... simply shutting down the service isn't enough."

Liao Feng: "What do you mean?"

Li Qing: "This serious bug has been going on for several days, so it has caused huge damage to the game's ecosystem."

Liao Feng: "Just tell me straight, what are we going to do? Ban the account?"

Li Qing: "There are too many players involved now. According to incomplete statistics, more than 20,000 to 30,000 players used this malicious bug to farm gold coins. Especially in the last hour after the bug was made public, a large number of players joined in. Banning so many accounts is almost impossible. The only solution is to roll back the data to 6 days ago."

Upon hearing this, Liao Feng felt a chill run down his spine.

That would be terrifying.

After all, it's only been about half a month since the large-scale closed beta test started, and now it's been rolled back for six days?

Does that mean the player leveled up for nothing during those six days?
All the equipment I acquired was for nothing.

Liao Feng: "Wouldn't it be enough to just roll back the gold coin data, but not the upgrade data or the equipment data?"

Li Qing: "No, after these people got the gold coins, they bought a lot of items to upgrade and craft equipment, so they're all tied together."

Liao Feng roared angrily, "Why was this bug discovered so late? Why wasn't it discovered earlier?"

Li Qing remained silent.

Who the hell is to blame?

I've said before that this game is incomplete and needs to be gradually closed beta tested and improved before finally launching a large-scale internal beta test.

As a result, if you force a large-scale internal test ahead of schedule, bugs are inevitable. Once a bug appears, you will use it as an opportunity to fire some people. Even if someone discovers the bug, they will not dare to report it.

After a long pause, Liao Feng said, "A six-day rollback is impossible; a two-day rollback is possible!"

"If the rollback is only for two days and the relevant accounts are banned, how many accounts will be affected?"

Li Qing: "We don't know yet, but there should be several thousand."

Liao Feng: "Go check it immediately and then tell me the accurate data."

"But if there are fewer than five thousand, shut them down without hesitation!"

..........................................

As a result, Perfect World experienced its second abnormal server shutdown.

What's even more ridiculous is that the server had just been down for maintenance yesterday. The team that first discovered the bug should have reported it and fixed it back then.

But they made a killing.

So let's pretend none of this happened.

People could barely forgive the previous abnormal server shutdown.

This time, the server shutdown announcement stated that three days' worth of data would be rolled back.

Instantly, countless players went wild.

Depend on!
They exploited bugs to farm gold coins, but we didn't do that.

I worked so hard to level up and farm equipment, and you just rolled back my data like this?
Why?

On both Renren.com's gaming community and Facebook's gaming community, a massive number of posts appeared, vehemently criticizing "Perfect World".

What are you doing?
Is this how you treat us during the Chinese New Year?
In order to quell public anger, Renren Games had no choice but to issue another announcement.

To compensate players for their losses, all players who log in within 24 hours after the server maintenance will be able to receive half a month's worth of game time cards.

Only then did a large number of players reluctantly forgive.

However, this bug has already caused the first wave of significant damage to the game.

..........................................

That's right, another Spring Festival is coming soon.

Meanwhile, the "Happy Farm" game on Facebook continued to gain popularity.

It's already becoming a hit and is poised to go mainstream.

The sponsorship deals for this year's Spring Festival Gala were finalized not long ago.

At that time, the entire senior management of Renren Group also held a board meeting.

Most shareholders strongly opposed sponsoring the Spring Festival Gala again, feeling it was completely unnecessary, given that Renren's IP and PV traffic were already far ahead.

However, Wu Lingxi insisted on sponsoring the Spring Festival Gala because she knew clearly that Renren.com's traffic was about to face a bottleneck and even begin to decline, so the Spring Festival Gala was needed to give it another strong boost.

If you can hold on for a few days, then hold on for a few days.

At least, this prosperity will last until the arrival of Masayoshi Son and Jerry Yang.

At Wu Lingxi's insistence, the entire board of directors once again approved the decision to sponsor the Spring Festival Gala.

Another tens of millions of RMB.

Back then, and last year, the biggest cost was in the lottery, where we spent astronomical sums of real money on users to participate in the lottery.

But there definitely won't be as many this year.

Furthermore, this year a series of conditions have been set, such as sending New Year's greetings to get a chance to win a prize.

For example, you can earn points by forwarding, liking, and other interactive activities, and then get a second or third chance to win a prize.

In short, it's about using the least amount of money to generate the most traffic.

Liao Feng and Wu Lingxi boarded a plane to Beijing once again to participate in this year's Spring Festival Gala.

He heard the report before boarding!

"Mr. Liao, the total number of online users has still exceeded 15!"

"Our distribution of game cards is effective."

"And although the number of online users is down by more than 100,000 compared to the peak, that's because of the Chinese New Year."

"This serious bug, although it caused damage, did not cripple our game."

Immediately, Liao Feng breathed a sigh of relief.

Upon arriving at the airport, they discovered Lin Xiao, Wu Jing, Ning Hao, and Li Duanduan.

Lin Xiao was once again invited to participate in the Spring Festival Gala.

He still did not sponsor the Spring Festival Gala, but this year "The Last Days" was so successful, setting a global box office record and being regarded as a huge victory for cultural export, so the program team invited him and the film's main creators to participate again.

Moreover, singers from the "Lightning" genre will once again grace the Spring Festival Gala stage this year.

Even the winner of "China's Got Talent" will perform on the Spring Festival Gala stage, which is unprecedented in history.

A while ago, Britain's Got Talent also held its grand finale, where Fei Fei Qu and the armless pianist performed in front of the British royal family.

Qu Feifei continued to perform opera, but with increased difficulty.

This caused a strong reaction.

After the performance, the Crown Prince shook hands with Qu Feifei and hugged the armless pianist.

Therefore, Qu Feifei has truly become a household name.

Their ranking on the CCTV Spring Festival Gala this year has also been greatly improved.

The two groups met at the airport, and then met again on the plane.

In fact, Lin Xiao and Wu Lingxi were even seated right next to each other.

Throughout the entire process, Wu Lingxi remained expressionless and as cold as ice.

Because this plane is not a large aircraft, it does not have a true first class cabin, only a business class cabin, and the seats are only slightly more spacious.

When Lin Xiao went to the bathroom, he accidentally stepped on Wu Lingxi.

I really didn't mean it.

As a result, Lin Xiao suddenly felt a pain on the top of his foot.

Because Wu Lingxi's pointed high heels were stepping on his feet, and she was secretly applying pressure.

Then, using the newspaper as a cover, she glared at him with a very fierce look.

Just look at that gaze.

That's absolutely stunning.

This woman, whose looks are off the charts, always has a poker face; she's never shown such a vivid expression before, not even a fierce one.

After glaring at Lin Xiao, she ignored him completely, maintaining her cold expression as she continued reading her newspaper.

It seemed as if his entire body exuded a chilling aura, keeping everyone at a distance.

..........................................

That evening during the Spring Festival Gala, Lin Xiao's table happened to be next to Liao Feng's table.

From beginning to end, Wu Lingxi didn't glance at her once.

This year, she has once again become the most stunning face.

Last year, no one knew who she was, but this year everyone does.

She shone brightly on the Renren.com Super Girl competition.

While Renren.com's red envelope giveaway this year is far less generous than last year, its advertising efforts remain strong, almost identical to last year's.

Throughout the entire show, every hour on the hour, the host would read out an advertisement for Renren.com.

The Renren website address will also appear on the screen.

Renren.com, the world's leading social networking site, reminds you to participate in the hourly lucky draw!

"This year's Spring Festival Gala is specially sponsored by Renren.com, the world's number one social networking site."

And similar advertising slogans.

Lin Xiao was once again filled with admiration. The entire Renren.com community felt that they had won in terms of traffic, since they had always believed they were far ahead.

Furthermore, Facebook hasn't publicly disclosed IP and PV data, and has even separated Facebook and YouTube. Despite this, Wu Lingxi remains deeply concerned and continues to spend heavily on CCTV's Spring Festival Gala, pulling out all the stops to create a stir.

We must carry this prosperity through to the end.

We need to put on a complete show for Yang Zhiyuan and Son Zhengyi.

This woman is incredibly resilient!
Immediately, Lin Xiao couldn't help but glance at Wu Lingxi's exquisite face.

Wu Lingxi's eyes remained fixed, but she could still sense Lin Xiao looking over.

What are you looking at? !
This sentence came to her mind, and it was a rare emotion for her.

She has always been aloof and never argues with anyone. Most of the time, she prioritizes her own interests and has no emotions.

They would never swear.

She has sworn at people countless times this year.

I basically send text messages every day, and I curse at people seven or eight times a day, sometimes dozens of times.

Get out, go to hell, you dog...

These words, surprisingly, became her usual writing catchphrases.

Liao Feng glanced at her curiously, because he noticed that Wu Lingxi's neck and above were gradually turning red.

She... actually blushed?

I've never seen anything like it before.

In an instant, Wu Lingxi's image in Liao Feng's mind seemed to come alive.

It went directly from being cold and aloof to becoming vivid and lively.

It stirred his heart, and he almost couldn't resist reaching out to hold it.

It seems she isn't incapable of feeling emotions. In special moments, she still can.

For example, right now, even with so many people around, and me, Liao Feng, staring at her like this, she still blushes.

Of course, it may also be related to Renren Group's recent huge victory.

After all, the entire board of directors opposed Renren.com sponsoring the Spring Festival Gala again, and it was still Liao Feng who supported Wu Lingxi.

Moreover, Masayoshi Son and Jerry Yang will be visiting Renren Group in a few days, and victory is just around the corner.

Under these multiple stimuli, the icy beauty finally fell in love.

Just then, Lin Xiao felt his thigh go limp.

Damn... Li Duanduan's hand actually reached out from under the table and stroked his thigh.

Don't go crazy!

This is the Spring Festival Gala, watched by hundreds of millions of people. If we are exposed, we will be completely disgraced.

Damn, the nickname really wasn't wrong.

You, Li Duanduan, are truly a vixen, a real seductress.

Moreover, her soft hand, like a snake, slowly moved upwards, heading towards Lin Xiao's core.

But her eyes remained fixed on the stage, unblinking.

No one else noticed, but director Ning Hao did.

He had already seen through everything, and slightly turned his body to block other people's view.

Just as Li Duanduan's hand was placed on Lin Xiao's core, the show on stage finally ended.

Everyone applauded!

Li Duanduan withdrew her hand and clapped as if no one else was around.

Finally, the Spring Festival Gala, which lasted for several hours, came to an end.

Everyone left.

Liao Feng very gentlemanly draped a large down jacket over Wu Lingxi's shoulders.

Wu Lingxi didn't even glance at Lin Xiao before leaving the studio.

Only after boarding the bus and hiding in the darkness did she casually turn around and quickly search for someone in the crowd.

After returning to her room, Wu Lingxi immediately turned on her computer.

My work email inbox was immediately flooded with emails.

"Mr. Wu, it's a great success!"

"Our traffic has exploded once again."

"Whether it's IP traffic or PV traffic, it has once again reached a new peak."

"Tonight, Renren.com's traffic has surpassed all other websites, making it number one in China."

Wu Lingxi immediately opened the Renren.com community, which contained a large number of posts filled with angry insults.

Are you saying Renren.com is playing a trick on people?
Last year's red envelopes were so big and so sincere.

What about this year? They've completely abandoned all shamelessness in their pursuit of traffic, making people desperately earn points to win a chance to win a prize.

As a result, the odds of winning the prizes were much lower than last year, and there were many non-cash prizes available, such as tickets to the Renren Night event and game points for Perfect World.

It seems that netizens today are still too naive and haven't been "trained" by Pinduoduo.

Even so, the traffic was still booming.

Wu Lingxi knew she would be scolded, but she didn't care; after all, this was the final battle.

To achieve our goal in one decisive battle!
You can criticize me all you want, as long as my traffic is far ahead of others, that's all that matters.

After finishing her business, she took a shower and then changed into her pajamas.

I put on an eye mask, intending to go to sleep, but I couldn't fall asleep, as if I hadn't accomplished anything.

"Beep beep beep..." My phone vibrated.

She immediately picked it up and found it was her usual cell phone. When she opened it, she saw that it contained a text message from Liao Feng.

She didn't open it; she just tossed it aside.

Then, I still couldn't fall asleep.

After a while.

The phone rang.

This time it was that dedicated machine with only one number.

Xia Xi: "Baby, you look so beautiful tonight. I've been fantasizing about what you look like under your sexy dress all night long."

Wu Lingxi: "Get lost!"

Xia Xi: "Baby, go to the window. I'll be right across from you, watching you from the darkness."

"Please turn on the light so I can see your silhouette, okay?"

Wu Lingxi: "Get lost!"

Xia Xi: "You almost beat me to death, and you're still so heartless? You won't even let me look at you..."

Wu Lingxi: "Get lost!"

The text messaging stopped.

A good ten minutes or so later, another text message arrived.

"I really can't sleep, all I can think about is you. Can't I even just see you for a moment, let your image in reality match the one in my mind?

"Wu Lingxi, there's a limit to how much you can torture people!"

"Is it meaningful to torture people to the point of wishing for death but being unable to live?"

Wu Lingxi stood up.

Go to the window, open it, and turn on the light!
Suddenly, her stunningly beautiful silhouette appeared in the window.

Enchanting.

About a minute later!
She turned off the light and went back to bed.

Soon, a text message arrived.

Goodnight, my love!

Wu Lingxi gritted her teeth, hating herself for her actions, and threw the phone hard onto the carpet in a fit of rage.

Xia Xi, who works in the Shanghai Lightning Group office building, received a photo of Wu Lingxi standing by the window, her beautiful silhouette illuminated by the light.

Looking at the photo, she let out a deep sigh.

His gaze softened.

Then, he dialed Lin Xiao's number directly.

By this time, Lin Xiao was already fast asleep.

"Still sleeping?" Xia Xi said irritably, "Get up now."

"Let's review today's lessons and take in the new photos."

"If you run into this tomorrow, you need to react appropriately, understand?"

"Did you know? Renren.com's traffic has surpassed ours again because of the Spring Festival Gala, and tonight it has even topped the list."

"FUCK, Wu Lingxi is such a troublesome woman, you're completely useless."

"Where did your ability to chase bubbles go? If you were so capable, why would you be fighting like this until now?"

"Useless things!"

..........................................

At six o'clock the next morning, Wu Lingxi opened her eyes precisely like a robot.

The alarm clock didn't go off until several minutes after she woke up.

The first thing she did when she got up was almost instinctively to pick up her phone from the carpet, but just as she bent down to pick it up, she immediately realized what she had done.

People are most vulnerable when they have just woken up.

At this point, it's a matter of life and death.

Instead of picking up the phone, she stomped on it hard and went into the bathroom.

And just then, my phone rang again.

Don't look at it.

Don't answer it.

That's a vicious wolf, it's hunting you!
When it comes to deciding life and death, it's all about who is more ruthless.

Being soft-hearted will lead to your demise!
Then, Wu Lingxi ignored the text messages on her phone, went into the bathroom to wash up and change her clothes.

Drop drop!
Then, my phone beeped with a text message.

Finally, she picked up her phone again and looked through the text messages.

Good morning, baby.

"I know you've been awake for a few minutes now. I set an alarm to send you a good morning message, hoping that the first thing you see when you open your eyes is me."

"Remember to eat bacon, blueberries, and bananas today. No iced coffee or lemons. Your period is probably due tomorrow."

Wu Lingxi replied to the text message: "Get lost, you pervert!"

After dressing neatly, she went to the hotel's buffet restaurant for breakfast.

A moment later, Liao Feng sat down in front of her.

"Xixi, why are you eating bananas? Don't you dislike them the most?"

Wu Lingxi looked at the bananas on the plate, then glanced at the hot coffee in her hand. She was almost on the phone and thinking about work when she got the food; all her actions were unconscious.

They inexplicably took blueberries, bacon, and bananas.

And I got a cup of hot coffee.

She drinks iced coffee every day, even on the coldest days, because it's more refreshing and makes her skin feel firmer.

Just then, her work phone rang.

"Ms. Wu, I am Yang Zhiyuan."

"Mr. Masayoshi Son and I are preparing to officially visit Shanghai on the 17th!"

Wu Lingxi said, "Okay, Mr. Yang."

Then, she put away the phone and said to Liao Feng, "Yang Zhiyuan and Mr. Son Masayoshi will visit on the 17th."

Liao Feng was immediately invigorated.

The fruits of victory are already within our grasp.

The final victory is finally within reach.

"I'm not eating anymore, I'm going back to my room first." Wu Lingxi got up and went straight back to her room.

After Liao Feng was excited, he suddenly thought of something: why did Yang Zhiyuan call Wu Lingxi instead of him, Liao Feng?

He is clearly the chairman of Renren Group.

After returning to her room, Wu Lingxi stood in front of the mirror and stared at her stunningly beautiful face.

What are you doing, Wu Lingxi?
Are you looking for death?
Are you courting death at this most critical moment?
Don't you know how insidious and ruthless that person is?
Then, he picked up the dedicated phone, gritted his teeth, and completely wiped out the text message database.

turn off the phone.

I simply pulled out the SIM card, threw it into the toilet, and flushed it away.

Then, he picked up his work phone, dialed a number, and asked, "Haven't you copied 'Happy Farm' from Facebook yet? Hurry up!"

After hanging up, she dialed another number, this time from Jack Ma of Tencent.

"Mr. Ma, I suggest you take a look at Happy Farm on Facebook. This game has a very high level of interaction. I think QQ Space can totally replicate it."

"Yes, it's just a small game, but I've been observing it for over half a month, and its social and interactive features are very strong."

She not only plagiarized "Happy Farm" herself, but also wanted QQ to plagiarize it as well.

Even though Happy Farm hasn't exploded in popularity yet, she already wants to encircle and suppress it from both sides.

Then, she called Li Qing, the person in charge of "Perfect World".

"Mr. Li, from now on, have your people keep a 24-hour watch on the game's ecosystem and all game communities."

"Report to me immediately if there is any disturbance."

"Whether it's a serious bug or a cheat, report it to me immediately."

"Not only will they not be expelled, but they will also be rewarded."

"A reward of 30,000 RMB will be given for discovering a serious bug. A reward of 50,000 RMB will be given for discovering a cheat."

"Immediate fulfillment, without delay."

Li Qingdao, the person in charge of Perfect World, said, "Mr. Wu, this should have been done a long time ago. But... the overall person in charge of the game is Mr. Liao. Won't he be unhappy about that?"

Previously, the division of labor was very clear: Liao Feng was in charge of games and Renren Video, while Wu Lingxi focused on Renren.com.

After all, Liao Feng made all the decisions in the game from beginning to end, and he was very sensitive to power. In the crucial decisions that followed, Wu Lingxi needed Liao Feng's cooperation, so she consistently stayed within her bounds and didn't interfere in the game's affairs.

But now... Yang Zhiyuan and Son Zhengyi are about to arrive, and we really can't afford any more major upheavals.

Therefore, Wu Lingxi had no choice but to intervene in the game's affairs once again.

After giving the instructions, she worked as fast as she could to finish the task.

However, half an hour after finishing her work, she couldn't help but reach for her dedicated phone, forgetting that the SIM card had already been removed and the data recharged.

Soon, my work phone rang.

"Ms. Wu, it's almost time to head to the airport," her assistant called to remind her.

Wu Lingxi: "Are Lin Xiao and the others on this plane?"

Assistant: "I don't know, but I think they're here."

Wu Lingxi: "Rebooking, the next flight."

The assistant was taken aback, then replied, "Yes!"

Soon, Liao Feng sent a text message asking why she had changed her flight, but Wu Lingxi did not reply.

....................................

Next, the entire Renren Group entered its final sprint to welcome Yang Zhiyuan and Son Zhengyi.

In the days leading up to the Spring Festival, the number of online players in Perfect World remained relatively low, partly due to the rollback of previous data and partly because people were visiting relatives and friends.

However, a few days before the Spring Festival, the number of online users began to gradually recover.

Following this trend, it's believed that when Yang Zhiyuan and Son Zhengyi arrive, the number of online players will reach a peak.

And it was on February 14th, which was Valentine's Day!
Around 10pm.

Li Qing, the person in charge of Perfect World, called.

Wu Lingxi answered the phone immediately.

"Mr. Wu, a serious bug has been found! A serious bug has been found!"

"You can duplicate high-level equipment in the game!"

Wu Lingxi wasn't a big game expert, but she immediately sensed the seriousness of the situation and asked, "How serious is this compared to the last bug?"

Li Qing: "This bug is even more devastating!"

Wu Lingxi: "How long have you been here?"

Li Qing: "It took no more than two hours. We have to thank General Manager Wu for his decision. Everyone's enthusiasm for finding bugs and uncovering cheats has increased like never before."

Wu Lingxi: "Immediately reward the person who reported this with 30,000 yuan, right now!"

"The game will be temporarily shut down for maintenance to fix bugs!"

Li Qing: "Yes!"

A moment later, Liao Feng rushed into Wu Lingxi's office.

"Wu Lingxi, give me an explanation!"

"We agreed that the game is my territory, and you won't interfere."

"And we just did maintenance yesterday, and now we have to temporarily shut down the service again?"

"Lin Xiao's 'Zhu Xian' is going into closed beta tomorrow, and we're going to have to shut down the servers again?"

Is this child's play?

"Which side are you truly on?"

....................................

Note: This climax will be completed in the next few chapters. I will do my best to write it well. If you have any monthly tickets, please give them to me, okay? Thank you!

(End of this chapter)
