Ye Feng's palm suddenly probed, grabbed Wang Lingyun's throat, directly lifted him up, and then jumped forward, returning to the previous position of the iron prison.

And on the side of this iron prison, Murong Zhang also killed all those Lingwu realms, and at this moment, he was standing on the side of the iron prison, thinking about something.

"Teacher Murong, Wang Lingyun, I brought it here. Ye Feng carried Wang Lingyun, walked to Murong Zhang's side, and said with a smile.

"Wang Lingyun, where is the key to this iron prison, quickly take it out for me. Murong Zhang was slightly stunned, then turned around and looked at Ye Feng and Wang Lingyun, then locked his gaze on Wang Lingyun and scolded coldly.

He had observed the iron prison for a long time before, and he had tried to attack, but because the iron prison was so strong, it was difficult to open it, even with his ability.

Moreover, he also discovered that this iron prison seemed to have a special power, which would slowly erode the body's meridians, making it impossible for the spiritual energy to operate.

Moreover, the longer this erosion lasts, the more fragile the body's meridians will become, and in the end, they will all have to be shattered, which is an extremely terrifying thing for cultivators.

"There is no key to this iron prison. Hearing this, Wang Lingyun smiled coldly, and then said with a smile, as if he was showing off something he was very proud of.

However, when he heard this, Ye Feng raised his palm and slapped it towards Wang Lingyun's face, and scolded angrily: "Believe it or not, I'll knock out your teeth!"

"Ye Feng, this iron prison seems to be able to erode the meridians, if you don't release your friends early, I'm afraid it will cause great damage to their bodies. And looking at Wang Lingyun's appearance, Murong Zhang on the side couldn't help but remind Ye Feng again.

Listening to Murong Zhang's words, Ye Feng's face instantly became solemn, then he looked at Wang Lingyun and asked in a cold voice, "I'm asking the last time, where is this key?"

"It's true that there is no key, this iron prison is something from a long time ago, and I just happened to get it. Wang Lingyun was slightly stunned, and after a moment of silence, he said lightly.

"Bastard!" Ye Feng immediately became furious when he heard this, Murong Zhang had already said that this iron prison could erode the meridians of the human body, if Zhen Haoshuang and them continued to stay in this iron prison, the consequences could be imagined.

Their meridians will definitely be completely shattered, resulting in the inability to gather spiritual energy in their lifetime, just like Ye Feng completely became a waste person who couldn't absorb spiritual energy at all a year ago.

"Don't kill me, I know how to open this prison. Wang Lingyun had already clearly felt Ye Feng's killing intent, and at that moment, a touch of fear couldn't help but rise in his heart, and after he was silent for a moment, he hurriedly begged Ye Feng for mercy.

"You advise you not to play any tricks, or I will definitely make your life worse than death. Ye Feng listened to this, and then he restrained his killing intention, and looked at Wang Lingyun in front of him indifferently at the moment, and said angrily.

"This iron prison is made of soul iron, and his hardness is comparable to a fifth-order Horcrux, if you want to get him open, then at least a fifth-order Horcrux is needed. Wang Lingyun looked at Ye Feng and finally calmed down, and his heart was also a lot more relaxed at the moment, he pondered for a moment and spoke.

"Although my Golden Yang Knife is a fourth-order Horcrux, it can exert the power of a fifth-order Horcrux, how can it not split this soul iron. Wang Lingyun, I think you're talking nonsense, you have to pick your skin!" Listening to Wang Lingyun's words, Ye Feng's face once again showed a trace of killing intent, his sharp gaze shot at him, and a murderous aura was spreading.

"What I said is true, soul iron is an ancient thing, but it has absorbed the energy of heaven and earth for more than a thousand years and melted into its own body. Not to mention a fourth-order Horcrux, even a fifth-order Horcrux wouldn't want to smash it. Only the best that surpasses the fifth order can cut off the soul iron. Wang Lingyun watched Ye Feng's golden yang knife slowly reach his neck, his face was instantly covered with a layer of horror, and then he said in fear.

"Xiao Feng, what Wang Lingyun said is not false, soul iron is also graded, the longer the power contained in it is, the stronger it is, in fact, to build a Horcrux, sometimes you also need to add the material of soul iron, so that the Horcrux can become stronger. It seems that if you don't find a fifth-order or sixth-order Horcrux, this iron prison will really be difficult to open. Murong Zhang frowned, looked at this iron prison and sighed lightly, and said.

"Fourth-order horcruxes are rare treasures in this Luochuan Kingdom, not to mention fifth-order and sixth-order. Ye Feng was surprised when he heard this, he didn't expect that this iron prison would be so difficult to open, and even Murong Zhang was helpless against it.

After Ye Feng was shocked for a moment, he turned his gaze to Wang Lingyun again, grabbed his sleeve and scolded angrily: "Wang Lingyun, you hurry up and find a way to get a sixth-order Horcrux and open this iron prison." ”

"Sixth-order Horcruxes, don't say it's my Luochuan Kingdom, even if it's the Heavenly Wind Empire, I'm afraid I don't have any. When Wang Lingyun heard this, he was slightly stunned, and then said helplessly.

"Xiao Feng, you don't have to be embarrassed. Killing this Wang Lingyun is all a decision he made, if it weren't for him, we wouldn't be locked up in this iron prison. At this time, Zhen Haoshuang in the iron prison suddenly spoke, his face was extremely pale, and he looked very weak.

"Haoshuang, Shen Mingxu, how are you feeling now?" Looking at Zhen Haoshuang's painful appearance, Ye Feng couldn't help but feel very guilty in his heart and asked.

"I can feel that there is a special force destroying my physical body, and now I only feel that the spiritual energy is being consumed extremely quickly, and it seems that just like Teacher Murong said, our meridians are slowly being destroyed. Zhen Haoshuang smiled bitterly and said.

"Ye Feng, don't worry too much. We only have one request now, and that is to ask you to kill this bastard quickly!" After Zhen Haoshuang finished speaking, Shen Mingxu also raised his forehead, and with countless scars on his face, he said to Ye Feng.

"Yes. Ye Feng looked at Zhen Haoshuang, Shen Mingxu and the rest of the brothers, he slowly lowered his head and assured him, and then turned around again and looked at Wang Lingyun.

Thinking back to the scars on Zhen Haoshuang's body and face, Ye Feng's heart rose with anger, and his fists clenched and made a "crunch" sound.

"Wang Lingyun, you really damn it, since they all said that they wanted to kill you, then I had no choice but to kill you. Ye Feng looked at Wang Lingyun, his face suddenly stiffened, and then his palm was raised, carrying a devastating force, and it bombarded his face.

"Don't hurt my son!" However, to Ye Feng's surprise, at the moment when Wang Lingyun was about to make a move, Wang Lingtian in the distance hurriedly arrived, and used his already vulnerable body to resist Ye Feng's blow.

"Uhh

Ye Feng was shocked when he saw that Wang Lingtian, he didn't expect that Wang Lingtian, who had become a waste, could still have that kind of speed and rush to the rescue when Wang Lingyun was at the last moment.

"Father!" Wang Lingyun looked at his father, flew out under Ye Feng's palm, and immediately took steps and ran into the distance, and when he walked to Wang Lingtian's side and found that he had died tragically, his eyes were immediately red, and he wanted to break Ye Feng's body into pieces.

But soon, Wang Lingyun dispelled this idea, because he understood that he now had no capital to compete with Ye Feng.

"You have already killed my father, and it can be regarded as revenge, so please let me go. After Wang Lingyun was silent for a moment, he walked up to Ye Feng and said beggingly.

"One life for one life, since your father is willing to die for you, then I will spare you for the time being. However, you have to find a way to release my brother. In case Zhen Haoshuang and they lose their cultivation like this, hehe, I have to abolish your cultivation and cut off your hands again. Hearing this, Ye Feng sighed lightly, he was not such a cold-blooded person, but if it weren't for Wang Lingyun and the others, it would be impossible for Zhen Haoshuang and the others to suffer such pain, so he had to bear all this for Wang Lingyun.

"I have a way!" Listening to Ye Feng's words, Wang Lingyun was simply afraid, and after thinking about it for a long time, he suddenly showed a trace of joy on his face and said.

"What's the way?" Seeing Wang Lingyun's happy appearance, Ye Feng also asked.

"I, the royal family of the Luochuan Kingdom, have a sixth-order Horcrux, but this Horcrux is very ancient, and it may not be able to cut off this iron prison, but we can give it a try. Wang Lingyun showed a smile on his face without a trace, and then said to Ye Feng.

"Is there really such a treasure?" Listening to Wang Lingyun's words, Ye Feng was also slightly moved, the sixth-order Horcrux can exert the power of the Spirit Sect Realm, this level of Horcrux, even if it is a large empire, is only a handful, it is a real artifact!

"Yes. Wang Lingyun looked at Ye Feng's happy appearance, a sinister smile flashed on his face again, and then said seriously.

"Alright then, I'll trust you for once. Ye Feng looked at Wang Lingyun, and after being silent for a moment, he said lightly.

Now if you want to open this soul iron, it is completely impossible to rely on your physical body, although General Murong's strength is already in the Spirit King Realm, even a fifth-order Horcrux may not be able to possess such a powerful power.

However, soul iron is the strongest thing, and it can only be broken by using high-level Horcruxes, so it is necessary to find a Horcrux above the fifth order.

"Then let's go. Ye Feng looked at Wang Lingyun and said, after finishing speaking, his figure flashed, and he grabbed a few imperial city guards who had not completely dispersed around.
