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

Lu Feng thought for a moment and felt that what Jian Yi said made sense.

Lu Feng put away his sword and said to the city lord: "I will spare your life today, but the premise is that you must explain to me clearly what is going on in this Sin City."

The city lord lay on the ground in silence. There were some things he could not say, and he dared not say them.

Looking at the silent city lord, Lu Feng's sword tip moved forward a little more, and the sword of time and space cut his skin, and blood flowed from the city lord's neck...

"If you keep silent, don't blame me for being ruthless. Originally, I could spare your life for the sake of your daughter, but you have to know that I don't have that much patience..." Lu Feng said in a deep voice.

When Xue Bier saw her father bleeding, she hurriedly persuaded him, "Dad... just tell me, is there anything more important than life?"

"Your daughter is right. What is more important than life? You may not be afraid of death, but if I don't get what I want, I will massacre this sinful city. I will not let go of anyone and everything in the city..." Lu Feng said in a deep voice.

The city lord was stunned, his eyes widened in disbelief. He had not expected the man in front of him to be so cruel. He did not care whether other people died or not, but he would not allow his daughter Xue Bier to be harmed in any way...

"No need to stare at me like that. I always keep my word. You can try and see if I will massacre everyone in this city!" Lu Feng said coldly.

Seeing his expression, Lu Feng knew that his bet was right. There must be someone or something in this sinful city that he couldn't let go of...

Xue Bier was also shocked. Lu Feng's cold look scared her. She believed that Lu Feng would kill her father...

"Daddy... just tell me. If you don't, you will die. Can you bear to see so many people in the City of Sin die?" Xue Bier said.

The city lord gritted his teeth and finally said, "This is all a conspiracy of the devil."

Lu Feng frowned and asked: "Demon God? Why would he do this?"

The city lord sighed and continued, "I'm not sure either. My Sin City is just a part of it. I only know that the Demon God is the boss behind the scenes..."

Lu Feng frowned, looked at everyone in confusion and asked, "Have you heard of the Devil?"

Everyone shook their heads. They had never heard of the name Demon God.

"Son of God, we have never heard of the devil..." Su Yao said.

"Master, I have never heard of any demon god..." said the old man in black robe.

Lu Feng continued to look at the city lord and said in a cold voice, "Go on, tell me everything you know!"

"I only know that all the slaves will be sent to our Sin City. I am in charge of making these slaves take the Soul-Separation Grass, so that they will become neither human nor ghost..." said the city lord.

After listening to her father's words, Xue Bier took two steps back in disbelief and almost fell down.

She had always respected her father, but she had never expected him to be such a person. Before, she had thought that these people were sinners, and that they were punished for their behavior. She had also thought that her father had always been protecting them and providing them with a place to live...

At this moment, the image of her father in her heart collapsed.

"Daddy...why are you doing this?" Xue Bier asked disappointedly.

"Alas... If I don't do this, someone else will do it. But if I don't do it, they will kill me and you. I don't want to do that, but they are devils and I don't want to do that. So there will only be you and me left in our family..." said the city lord.

"How...how could this happen? But I don't want you to do anything bad. They are all innocent..." said Xue Bier.

Lu Feng was stunned. It seemed that the city lord’s weak spot was his daughter.

"What happened after you made them like this?" Lu Feng asked puzzledly.

"After we successfully transform them all into something neither human nor ghost, someone will come and take them away, but I don't know where they will be taken..." said the city lord.

Lu Feng nodded, realizing that this should be a huge network, but he still couldn't figure out what the people behind it were going to do...

And this Sin City is just a small part of this huge network...

It didn’t matter whether Lu Feng knew what this huge network was doing or what conspiracy it had. For Lu Feng, the most important thing now was how to solve his master’s problem…

"These don't matter. Let me ask you, my master has been turned into neither human nor ghost by you using the Soul-Separation Grass. Even I can't recognize him. How can I make him return to normal?" Lu Feng asked puzzledly.

Unexpectedly, the city lord also shook his head and said, "I don't know how to solve it specifically. It is very likely that there is no way to solve it at all. It will always be like this..."

Lu Feng was dumbfounded. The city lord's words were like a thunderbolt that struck him on the head...

Lu Feng couldn't accept this statement. Could it be that the old man would always be stupid and foolish?

Obviously, Lu Feng was unwilling to accept this result.

After finally finding the old man, he turned out to be a foolish and stupid old man who even Lu Feng didn't recognize. How could Lu Feng accept this?

Lu Feng turned to look at Jian Yi and asked in a deep voice, "You know how to solve it, right?"

Jian nodded and said, "Indeed, I know a solution, so I said only you can solve it..."

Lu Feng was delighted and asked quickly, "What's the solution? Tell me..."

Lu Feng was also a little confused. What was the solution? Why was he the only one who could solve it?

Lu Feng really couldn't figure it out...

"You have mastered the Hongmeng Purple Qi, right?" Jian Yi asked.

He stared at Lu Feng, and it was obvious that the answer was very important to him. He wanted to see if Lu Feng was lying.

Knife 2, Spear 3, Axe 4 and others all looked at Lu Feng expectantly, waiting for Lu Feng's answer...

The city lord was shocked. Hongmeng Purple Qi? The person in front of him actually mastered it?

Lu Feng's eyes narrowed slightly, and he nodded and admitted: "Yes, I have indeed mastered the Hongmeng Purple Qi."

Jian Yi heaved a sigh of relief after hearing this, and then said, "That's easy. As long as you use the Hongmeng Purple Qi as a guide and combine it with several other immortal medicines, you can refine an antidote to remove the toxicity of the Soul-Separating Grass."
