After more than ten years on the mountain, you will become invincible when you come down.

Lu Feng looked at the young man who brought him over and said in a deep voice, "You say!"

The young man was stunned, and quickly explained, "It was the silly boy I sold to your Black Wind City a month ago, named Niu Gen, who was the person he was looking for..."

"I don't care who the person you are looking for is. Since he has been sold to Black Wind City, he belongs to us. You can take him away as long as you pay the corresponding fairy crystals! We in Black Wind City are open for business and we do not cheat anyone!" said the manager.

"So, you want me to pay for it with immortal crystals?" Lu Feng sneered.

"But that's fine, as long as you can hand over the person, offer a price!" Lu Feng continued.

Immortal crystals are external things, and now Lu Feng’s only goal is to rescue Niu Gen smoothly and safely...

Paying some fairy crystals, what’s the big deal?

“I don’t know whether the Niu Gen you mentioned is still in Black Wind City. If it has been traded, then I can’t do anything about it. Please wait a moment, I will first find out whether the Niu Gen you are looking for is still in our Black Wind City…” said the manager.

In their Black Wind City, every transaction is recorded clearly. When it was sold to Black Wind City, when it was traded to where, everything is documented...

"You'd better not play any tricks. If you dare to do so, I will not let you off!" Xiaolong shouted in a deep voice.

"Don't worry. I have already experienced how powerful you are. Harmony brings wealth. If this Niu Gen was still in our Black Wind City, I would not hide him. Harmony brings wealth. Since he has come to our Black Wind City, he is our guest. It doesn't matter who I sell to. In this case, there is no need for me to make things difficult for you, right? As long as Niu Gen is in our Black Wind City, and as long as we don't lose money, I can trade him to you. How about it?" The manager said with a smile.

As the saying goes, don't hit a smiling person. No matter what, we need to find Niu Gen's whereabouts first, and the manager in front of us obviously has the authority in this regard.

In this case, Lu Feng has no reason not to agree...

"Okay, then you go check it out first, and we'll go around and I'll pay as much fairy crystals as you find out!" Lu Feng agreed.

"That's great..." the manager said and turned to leave, apparently going to look up Niu Gen's information.

After the manager left, Lu Feng had nothing to do, so he wandered around.

Lu Feng looked around and found that the buildings on both sides of the streets in Black Wind City were filled with slaves.

These slaves were also divided into different levels, including high-end slaves, middle-end slaves, and low-end slaves...

Male slaves and female servants were also separated and not held together.

"How do you distinguish the levels?" Lu Feng asked the Black Wind City personnel who were following him.

These people were frightened by Lu Feng's beating. Ever since the manager went to look up Niu Gen's information, they followed Lu Feng to prevent him from causing trouble here...

"That's right. We classify slaves based on their talent, appearance, age, cultivation, etc...."

"The better the appearance, the higher the score? The younger the person, the higher the score?" Lu Feng asked puzzledly.

Because Lu Feng also discovered that in some buildings, the slaves imprisoned were relatively good-looking...

"That's right. Whether it's a male slave or a maid, everyone likes young, beautiful or handsome ones. If they have a good figure, that's a plus. They can sell for more immortal crystals. In fact, talent is secondary..."

"Oh? Isn't there any requirement for high talent?" Lu Feng asked doubtfully.

"Yes, there are. The requirements for talent are relatively high. These are called battle pets. Some will be kept in Black Wind City, and some will be bought..."

"So, you are such a group of war pets that were taken in by Black Wind City?" Lu Feng asked doubtfully.

Everyone shut their mouths, lowered their heads, and stopped talking, looking very secretive...

Lu Feng had a preliminary understanding of the overall situation of Black Wind City...

It seems that the person behind the scenes of Black Wind City is using enslavement to manage the human race. Lu Feng is also very curious about what kind of person can come up with such a crazy idea...

The key is that this crazy idea probably brought him huge benefits...

After a while, the steward returned.

"After some investigation, I found that the Niu Gen you are looking for was indeed in our Black Wind City, but he was traded not long ago..." said the manager.

Lu Feng was startled and asked quickly, "Where did you sell it to?"

"Don't worry. Although it has been sold, we can help you buy it back. I have already contacted the other party. They said that as long as you give enough fairy crystals, it is not impossible to trade it back..." said the manager.

Lu Feng's eyes lit up. The matter of immortal crystals was easy to deal with. Immortal crystals were external possessions. He could buy Niu Gen back by just paying some immortal crystals. Why not do it?

"What's the price?" Lu Feng asked hurriedly.

The steward smiled and held up five fingers.

"Fifty immortal crystals?" Lu Feng frowned.

"You're joking. Fifty fairy crystals are not enough for the money we spent on buying him..." said the steward, shaking his head.

"Fifty thousand?" Lu Feng asked again.

The manager shook his head again...

"How much do you want? Just tell me directly!" Lu Feng said in a deep voice.

Lu Feng was too lazy to guess, so he just paid for it himself.

"For five million fairy crystals, the other party will be able to trade Niu Gen back. If you are interested in buying it, I can be the middleman for free and will not charge you any fees..." said the manager?

Lu Feng's face darkened, "You are just asking for too much!"

The manager spread his hands and said, "There is no other way. The owner of Niu Gen is not someone you will mess with. If it weren't for your sincerity, I would not tell you his whereabouts. Besides, this price was set by the other party and has nothing to do with our Black Wind City..."

Lu Feng gritted his teeth and finally decided to compromise, "Okay, five million immortal crystals is five million immortal crystals, but I want to see the person right away."

Immortal crystals are external things, so the most urgent task now is to rescue Niu Gen first.

Now that he hadn't even seen Niu Gen, Lu Feng couldn't get angry. If he fell out with Niu Gen now, it would be even more difficult to find Niu Gen later...
