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

"I guess this is the city lord, right? We are indeed passing by here. We have been walking in the desert for a long time and wanted to go into the city to rest. Fairy Xuebier brought us in. We apologize for disturbing you..." Lu Feng said.

"I don't care who you are, get out of the City of Sin right now, or don't blame me for being rude! My daughter is naive and easy to deceive, but I'm not that easy to deceive!" said the city lord in a cold voice.

"Why are you like this? I thought you were a kind person, taking in so many sinful people. I didn't expect you to be so rude and want to drive us away without any reason!" Xiaolong said unhappily.

"Hmph! Driving you away is the easiest thing I can do. If you don't leave, then you don't have to leave!" the city lord snorted coldly.

"Dad, they have come a long way and are exhausted. How about letting them stay here for one night and letting them leave tomorrow morning?" Xue Bier said softly.

"Alas...Xue'er, you are too kind and easily deceived by others..." the city lord sighed.

"Look at your daughter, she is much better than you. I even doubt whether your daughter is your biological daughter..." said the old man in black robe.

The city lord glared at the old man in black robes and said nothing. He turned to look at Lu Feng and the others, and after thinking for a moment, he said, "Well, since my daughter pleads for you, you can stay in the city lord's mansion for the night. But you must leave this place tomorrow morning!"

Lu Feng bowed and thanked him: "Thank you, City Lord."

"Hmph, if you want to thank someone, thank Xue'er. If it weren't for her kindness, you would never be able to spend the night here!" The city lord snorted coldly.

"Thank you Miss Xue Bi'er, thank you Lord Mayor!" Lu Feng bowed.

"Come, take these people to the guest rooms to rest!" the city lord ordered.

Afterwards, the city lord took Xue Bi'er away.

Xiaolong complained to Lu Feng: "What kind of person is this? He's so fierce."

"Forget it. When you're under someone's roof, you have to bow your head. After all, they're letting us stay here for the night. It's normal to feel reluctant..." Lu Feng comforted.

"But I feel that there is something weird in this city. The city lord and his daughter are also weird. How can such a bad-tempered city lord give birth to such a kind daughter?" Xiaolong asked puzzledly.

"Maybe, his personality just changed for some reason? Anyway, we shouldn't interfere in other people's family affairs..." Chen Haoran said.

"Brother Haoran is right. This is their own business and has nothing to do with us. We will just rest here for one night and leave tomorrow. It does not involve us, so there is no need for us to meddle in other people's business..." Lu Feng said.

"Lu Feng, since we have discovered the abnormality and something is wrong, shouldn't we investigate it clearly?" Jian Yi suddenly said.

Lu Feng was stunned, and looked at Jian Yi repeatedly. After a long while, he said, "Jian Yi, I feel like something is wrong with you too..."

"Haha... Lu Feng, stop joking. What's wrong with me? I'm quite normal. But you, you found the abnormality but didn't investigate it thoroughly. You must feel very uncomfortable, right?" Jian Yi said.

"Since we entered the city, you have become a nobody and have said nothing. Now you are talking so much and asking me to investigate. Why do I feel that you were the one who arranged for us to come to this city of sin?" Lu Feng said in a deep voice.

Jian Yi was shocked and quickly explained, "How is that possible? We came out of the desert and encountered the City of Sin by chance. How could I have the ability to arrange it?"

"Okay, let's not talk about this." Lu Feng waved his hand, "Go and have a rest first, we'll talk tomorrow if there's anything."

The group followed the guards to the guest room and then went back to their rooms to rest.

The moon is high in the sky, and everything is silent.

Lu Feng couldn't fall asleep, as he always felt that there was a strange atmosphere in this city.

Almost everyone in the city has a slave seal engraved on them, after all, there are quite a few of these people in the fairy world.

But when Xue Bier said that these people were all sinners, Lu Feng did not dare to agree. People with slave seals obviously had a very low status in the fairy world, and there were few people with strong strength.

Since I'm already a slave, what sinful things can I do?

Even if they had committed a serious crime, who would care about their lives? How could they survive? This was a bit ridiculous...

Moreover, the gazes of these people were all empty and irrelevant, which seemed very abnormal...

Lu Feng decided to go out for a walk to see if he could find anything.

Lu Feng quietly pushed open the door, and in a flash, he disappeared into the darkness.

Lu Feng was strolling in the city, and as he walked, he came to a remote courtyard.

A series of strange noises coming from the yard caught his attention.

He leaped onto the top of the wall and looked into the yard.

I saw a dark shadow squatting on the ground, fiddling with something.

Lu Feng approached cautiously and took a closer look. The man turned out to be the city lord during the day!

The city lord at this moment had a focused look on his face, completely devoid of the violent temper he had during the day.

He held a strange plant in his hand and muttered something.

Just as Lu Feng was about to take a closer look, the city lord suddenly raised his head and looked straight in the direction of Lu Feng.

Lu Feng was shocked and flew away quickly.

The city lord stood up, a hint of doubt flashed in his eyes, but he quickly regained his composure.

He looked at the plant in his hand and said to himself, "Just a little bit more, and it will be successful..."

Lu Feng returned to the guest room, feeling increasingly uneasy.

He realized that this sinful city was hiding a huge secret, and the city lord's behavior was full of doubts.

"Lu Feng, there is definitely a big problem with this city lord!" Wutan suddenly said.

"Oh? Why are you so sure?" Lu Feng asked puzzledly.

"Do you know what the magic grass in his hand is?" Wutan asked back.

Lu Feng shook his head and said, "I don't know, I've never seen him before. Do you know him?"

"I do recognize him. The grass in his hand is the Soul-Separation Grass. I was wondering why the people in this city were so strange, with empty eyes and looking dull. Now I understand, it's because of the Soul-Separation Grass..." Wutan said.

"Soul-Separation Grass? What does this have to do with the empty looks in their eyes?" Lu Feng asked puzzledly.

"As the name suggests, the Soul-Separation Grass can make a person's soul gradually disintegrate if taken for a long time. In fact, it's not really disintegration, but it will just become like now, dull and stupid, with dull eyes, like a useless person. Just now I observed that he was crushing the Soul-Separation Grass. In that small courtyard, there are many wells. I guess that is the source of water for this city..." Wutan explained.
