Xu Chen and her companions entered the Dreamfall City. The streets here were prosperous and bustling, filled with powerful individuals from the three realms of heaven, humans, and demons, as well as wealthy people and their servants. The entire city was filled with flowing lights and dazzling neon signs. Every street was adorned with magnificent buildings. This was a highly secretive entertainment city for the powerful figures of the three realms.

"Hmph! This so-called entertainment city is nothing more than a red-light district!" Qingyin complained. "Xu Chen, there's no need to look around. All the women on this street are courtesans!"

"Don't worry, Qingyin, I'm not interested in these women who sell themselves," Xu Chen said.

"Good, that's more like it!"

They found a relatively quiet inn and paid the innkeeper, a fat demon, some money to stay. Although Qingyin and her group of beauties attracted attention, the people frequenting this place were all powerful figures from the three realms, making it impossible for ordinary people to enter. Therefore, no one would dare to have any improper thoughts about Qingyin and her companions.

Inside the guest room, Zi Wan entered and said, "Xu Chen, I've found out some information. Star Dance is most likely in the highest and most expensive entertainment venue in the city called the Palace of Nian Nu."

Zi Wan, being a female ninja, was skilled at gathering information.

"The Palace of Nian Nu?" Xu Chen asked.

"Yes, although Star Dance is the future princess, this place is not the royal palace of Meng Yan Kingdom. It is simply an entertainment city created by the ruler of Meng Yan Country for the three realms. There is no imperial palace here, so Star Dance is likely temporarily placed there," Zi Wan explained.

"Good! Let's find a way to blend in and take a look!" Xu Chen said.

Without delay, Xu Chen, Qingyin, and the four Demon Lords went straight to the Palace of Nian Nu.

However, they were stopped by a huge demon guarding the entrance. "Halt! This is the Palace of Nian Nu, the number one entertainment palace in the three realms. Ordinary people are not allowed to enter casually!"

Xu Chen casually took out a valuable treasure, one of the countless treasures he had seized from the lair of the Demon Emperor Swallowing Heaven's Grandmother. "We are not ordinary people. What's the matter? Are you afraid that I can't afford to play here?"

"Hmph, this young master is indeed extraordinary, but money is not enough to enter here. This is the Palace of Nian Nu, a membership-based establishment!" the guard replied.

"How does one become a member?" Xu Chen asked. "Money is not a problem for me."

The minotaur said, "The membership fee here is indeed astronomical. However, seeing how generous this young master is, it shouldn't be a problem. But in this establishment, membership requires bringing along a stunning female slave. Without one, even if you have money, you cannot enter. After all, those who can afford to play here don't lack money. This rule is also for the consideration of other powerful individuals with similar preferences. I hope the young master can understand. If you can bring a stunning female slave, you can join!"

"A female slave?" Xu Chen paused. "That shouldn't be difficult."

"Young master, with your wealth, it won't be a problem to find a woman and call her a female slave, right?"

"How so?"

The minotaur took out a purple crystal-shaped identification card. "Young master, if you tie this token around the neck of your female slave, and her name appears on the token along with a magical glow, it means she genuinely submits to you as a servant, and is not an imposter. Also, the minimum strength requirement for a female slave is a Demon Lord. Otherwise, she won't be able to withstand the games in our Palace of Nian Nu!"

Xu Chen took the token and frowned. "I understand. I will bring a female slave next time."

The sisters returned to the inn and immediately gathered together to discuss.

"What should we do, Xu Chen?" Devol asked.

Xu Chen held the token and pondered for a moment. "Zi Wan, is the information you obtained reliable?"

"I can't guarantee it a hundred percent, but based on my years of experience as a female ninja and my intuition, I believe that if Star Dance is in this Dreamfall City, she must be in the Palace of Nian Nu."

Xu Chen had a hesitant expression. "If I were to storm into the palace now without knowing Star Dance's exact location, it might startle them and lead to Star Dance being moved elsewhere. In that case, the only way is for one of you to temporarily pretend to be my female slave and help me enter the Palace of Nian Nu."

"What's so difficult about this?" Qingyin said, "Xu Chen, let me play the role of a female slave! It's just about infiltrating, right?"

Xu Chen shook his head, "It's not that simple, Qingyin. Try wearing this name tag."

"Huh? I don't want it. Wearing a name tag means telling others that I'm a slave, right? It's embarrassing, I don't want it!" Qingyin shook her head.

"That's why I said..."

"Xu Chen! Let me do it!" The Maiden of the Celestial Realm took the name tag and hung it around her neck as she already had a scarf on.

"How dare you make decisions on your own!" Qingyin became agitated when she saw another woman wearing the name tag.

"Didn't you say you didn't want it just now?" The Maiden of the Celestial Realm argued.

"But... I was hesitating, I haven't made up my mind yet..."

"Alright, stop arguing," Xu Chen said, "Although The Maiden of the Celestial Realm is wearing the name tag, it's not glowing which means it's useless! Can you let me finish? The demon said that only slaves who sincerely submit will make the name tag glow!"

"Huh??" Everyone was dumbfounded.

"Let's give it a try!" Yule, Devol, and Zi Wan tried, but it didn't work.

Sakuko said, "You're all making a fuss for nothing. We are Xu Chen's companions, we don't consider Xu Chen as our master, and Xu Chen can't consider us as slaves. So how can there be sincerely submitted slaves?"

"Yeah..." Xu Chen hesitated, "It seems like one of the sisters will have to bear the burden and wear the name tag. At least for this period, she will sincerely serve as my slave. Perhaps it will require some difficult trials to prove her sincerity. As for what it takes to be a true slave, we can only keep trying different methods until the name tag glows."

Everyone fell silent.

"Why is everyone not saying anything? Are you all just going to watch Star Dance marry some prince?" Qingyin blamed.

Sakuko spoke, "Qingyin, of course, we are willing to sacrifice for Star Dance. However, we are not speaking because we all understand silently that only you are the most suitable for this."

"Huh?" Qingyin was stunned, "I don't want to! Going to some entertainment game party with a slave name tag, there will be many people there, won't everyone know that I'm a female slave? That's too embarrassing, I don't want to do it!"

Sakuko said, "Since you don't want to, then we can't force you. Among us sisters, let's see who is willing to go."

The Maiden of the Celestial Realm suddenly spoke, "To be Xu Chen's slave, it might require some intimate practice... Since I joined this team, I haven't contributed much, just freeloading. So, let me give it a try..."

She blushed slightly, took a step forward, and took the name tag, "Xu Chen, what specifically do I need to do?"

"Well, I'm not sure about the details, but it's about the relationship between a master and a slave..."

"That... " Qingyin's face turned slightly red, feeling anxious, what strange things would Xu Chen do with The Maiden of the Celestial Realm? It's obviously indecent, but it seemed to have such a legitimate reason?

She rushed over and snatched the name tag, "No, no! You shameless woman, how can you do those strange things with Xu Chen!"

"Hey! What are you doing, taking my name tag! Weren't you the one who said you didn't want to go?" The Maiden of the Celestial Realm retorted.

"Qingyin! You're in the wrong here!" Sakuko said, "We were all silent at first, out of consideration for your relationship with Xu Chen, afraid that you would be unhappy. That's why we gave you this opportunity. You refused it yourself, but as you said, we can't just watch Star Dance marry that idiot! You don't want it yourself, but you don't let others have it. What exactly do you want?"

"This......" Qingyin held the nametag in her hand, but her eyes looked elsewhere, her gaze was vague, and her face was flushed.

"What is it? If you don't want to go, I'll go!" The Maiden of the Celestial Realm wanted to snatch the nametag!

"What are you doing! Don't snatch it, I haven't made up my mind yet!"

"Stop!" Xu Chen shouted, "I understand Sister Sakiko's intentions. Indeed, Qingyin and I have come a long way and experienced a lot together. As for you, the Four Demonic Sisters, I have only known you for a short time. How can I ask you to do such a thing? However, rescuing Sister Star Dance is urgent. If Qingyin, you are unwilling, then I will have to trouble Sister Mayuri. After all, I don't want to force anyone."

Everyone looked at Qingyin.

"Annoying... Don't all look at me like that. It's embarrassing to say such things in front of everyone... embarrassing," Qingyin blushed.

Yule spoke up, "Sister Qingyin, if you feel embarrassed in front of us, how can you carry the slave tag and appear in front of so many strangers? I think it's better not to force it, let Sister Mayuri go!"

"Yes, Qingyin... Since Mayuri is willing..." Devol also advised.

Deep down, Qingyin didn't want to bring this nametag to showcase in front of the demons in the Nianu Palace. However, she was also afraid that The Maiden of the Celestial Realm would become closer to Xu Chen during the training because of the nametag. She thought and thought...

"I... I understand, I... I will bring it, that's it..."

Qingyin took out a black leather collar, lifted her long hair back, and fastened the collar around her neck. Then, she hung the nametag on the metal ring in front of the collar.

"How about this? Like this... is it okay..." Qingyin was originally wearing a black short shirt and skirt, black boots, and the black collar on her neck with the white orchid. Together with the nametag, she exuded a seductive and bewitching charm. Amidst her hesitant and shy expression, there was also a sense of compliance and resistance, truly innate...

"I have to admit, Qingyin wearing this nametag, along with her temperament and this outfit, is truly a perfect match," Devol smiled.

The Maiden of the Celestial Realm also sighed helplessly, "I'm sorry, Qingyin, I shouldn't have argued with you. When it comes to who is more suitable to play the role of a slave, I truly... am not as good as you!"

"You guys!" Qingyin didn't think these words were praising her. "What do you mean! How rude, sniffle..."

Xu Chen looked at Qingyin's appearance and also had some realization. Since being trapped in the space-time whirlpool for countless years, how long has he not truly been intimate with Qingyin? At this moment, he also felt a surge of desire to conquer this stunning woman in front of him, but...

Just then, Qingyin's nametag displayed her own name and sparkled.

"Huh?" Qingyin trembled all over.

"Huh?" The sisters were also stunned.

"Qingyin... Your nametag is... shining," Yule said in confusion.
