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

"This desert is too big. How long will it take us to get out of here?" Lu Feng couldn't help but complain.

"Hold on a little longer, there will definitely be a way out ahead." Jian Yi comforted.

Just when they were about to lose confidence, a hint of green appeared in the distance.

"It's an oasis!" Su Yao shouted excitedly.

"Let's go and take a look..." Lu Feng said.

Seeing the oasis meant that they were about to get out of the desert.

Everyone quickened their pace and walked towards the oasis. The closer they got to the oasis, the cooler they felt.

When they finally reached the edge of the oasis, they vaguely discovered a city in the center of the oasis...

"There is a city over there. There should be people in the city. Let's go in and take a look..." Jian Yi said, pointing to the city in the distance.

"Could it be another dead city?" asked the old man in black robe puzzledly.

"There aren't so many dead cities. Let's go and take a look first. I'm going to soak my feet in the city. I'm so tired..." Dao Er said and walked over.

"Let's go, everyone go and take a look. We finally came across a city. If anyone is here, it might as well stop here to rest..." Lu Feng said.

Everyone nodded and followed.

Soon after, everyone arrived at the city gate. Fortunately, this city was not a dead city.

However, it is not like other cities where people can come and go freely.

The gates of this city are tightly closed, and there are guards patrolling above the city, and the patrols are very intensive...

"City of Sin..." Lu Feng murmured as he looked at the big words on the city wall.

"Master, why is this city called this name? Could it be that all the people in this city are deeply sinful?" asked the old man in black robe.

Lu Feng also shook his head in confusion, "I don't know either. There are good people and bad people everywhere. I believe that the City of Sin is the same, it's just named like this..."

"Let's go over and see if we can get in..." Jian Yi said as he walked over.

He stopped at the foot of the tower, looked up at the top of the tower, and shouted loudly, "Brother, can we enter the city now?"

Jian Yi's shouting immediately attracted the attention of the guards, and a guard in black armor looked over.

"Everyone, where are you from? What are you bringing to my City of Sin?" the guard asked in a deep voice.

"We came from the Northern Territory and passed by here. We want to find a place to rest. Please be kind and let us in..." Jian Yi said.

The guard frowned and said in a deep voice for a while, "My Sin City does not welcome outsiders, please leave..."

Jian Yi frowned when he heard this, and clasped his fists and said, "Brother, can you please be flexible? We have traveled all the way here and are exhausted. If there is a vacant room in the city, we are willing to pay for it."

The guard was unmoved and responded indifferently: "I have already said that the City of Sin does not welcome outsiders. You should leave quickly and do not disturb the peace of the city."

Lu Feng took a step forward and said loudly: "Why are you so unkind, sir? Is there some secret in this city?"

The guard's eyes narrowed slightly, and he said in a deep voice: "This is the city lord's rule, I am just following orders. You guys go quickly, otherwise don't blame me for being rude."

Just when the two sides were in a stalemate, the city gate suddenly opened, and a carriage suddenly drove out of the city. The curtain was lifted, revealing a beautiful and cold face.

The woman opened her red lips and said, "Let them in." Her voice was as sweet as the sound of nature.

The general defending the city obviously knew this woman. He responded respectfully and waved his hand to let the soldiers pass.

"Thank you for your help, young lady. May I know your name?" Lu Feng bowed to the woman in the car to express his gratitude.

The woman nodded slightly, "My name is Xue Bi'er. It's not suitable to stay here for long, please follow me."

After saying that, the carriage turned around and drove back into the city.

Lu Feng and the others looked at each other and followed the carriage.

Lu Feng and others walked into the city and looked around curiously.

The town is not big, but the architectural style is unique and the streets are neat and orderly.

"Master, these people seem a little strange..." Xiaolong said as he looked at the people walking around.

Lu Feng also frowned as he looked at these people, because most of them had a characteristic, that is, a slave mark engraved on their foreheads, which was not seen in such a high proportion in other cities...

After hearing Xiaolong say that the people here were a little strange, Lu Feng observed carefully and found that everyone had dull eyes and didn't talk much. They just walked by themselves...

Before Lu Feng could figure it out, the carriage stopped in front of a mansion. Xue Bier got off and led them into the mansion.

The house was elegantly decorated and the servants were respectful.

Xue Bier asked everyone to sit down and ordered someone to serve tea.

"I guess everyone has questions about the City of Sin." Xue Bier looked at everyone and said softly.

"Please ask Fairy Xuebier to solve our doubts for us..." Lu Feng said.

"In fact, the reason why this city is named 'Sin' is because the people living in the city are those who have committed crimes." Xue Bier said.

Lu Feng and the others looked at each other in bewilderment, "But, since the guilty person is guilty, why not punish him?"

Xue Bi'er sighed, "Although they have made mistakes, they have received the punishment they deserve. The city lord wants to give them a chance to reform, so he built this town for them to live in."

Lu Feng nodded thoughtfully, "I see. Who is that girl? Why does she have the power to decide to let us into the city?"

Xue Bier smiled and said, "I am the daughter of the city lord. My father is away visiting friends, so I take care of his affairs."

"Thank you so much, Miss Xue." Lu Feng expressed his gratitude again.

Xue Bier waved her hand. "You're welcome. If you have any other needs, just ask."

"I have another question that I want to ask the young lady. I wonder if you can help me solve it?" Lu Feng said.

"Just say it." Xue Bier said.

Lu Feng pointed at the people with slave marks on their foreheads and said, "Why are these people in such a state? They seem to have lost their minds..."

A trace of sadness flashed in Xue Bi'er's eyes. "They were all cast under a special spell to punish them for their past sins. Although they were able to keep their lives, they lost their freedom and self..."

Just when Lu Feng wanted to continue asking questions, an angry voice came.

"Xue'er, who are they? Why did you let them in?" the man said angrily.

As the words fell, a thin man walked in, his eyes full of anger and dissatisfaction, looking at Lu Feng and others angrily.

"Dad, you're back. They were just passing by our Sin City, so we let them rest here. Didn't Dad say that we should be helpful? I thought it was not a big deal, so I brought them back..." Xue Bier said.
