At this moment, a towering figure appeared behind the Netherworld army. To call it towering was an insult to the figure itself.
This ghastly green shadow was at least tens of feet tall. Tall city walls, in its presence, became incredibly low, barely reaching its knees.
"The Netherworld Ghost King, he has arrived!"
Everyone cried out in alarm.
The Netherworld Ghost King was immensely powerful. His arrival struck a heavy blow, instantly shattering their psychological defenses.
Yun Fan, upon seeing him, realized the Netherworld Ghost King was powerful, but not as much as he'd expected, capable of causing hundreds of prodigies to bleed.
He should have been at least at Yun Fan's own cultivation level, but this so-called Netherworld Ghost King was only at the second stage of Immortal Emperor. How weak was that!
Now, the Netherworld Ghost King reappeared, roaring as he charged.
"Prey, are you ready?"
In an instant, he sprinted towards the city walls, and it seemed no one would escape.
At this moment, Yun Fan made his move. A world-shattering power descended, piercing the Netherworld Ghost King.
But the Netherworld Ghost King chuckled playfully, "Boy, your move won't cause me any harm. I am immortal! You can't do anything to me!"
"Is that so?"
The next moment, flames ignited within him, the Devouring Flames consuming his power. Yun Fan couldn't even be bothered to devour them.
This Netherworld Ghost King was too weak, unable to compensate for the energy consumed in his transformation.
With the Netherworld Ghost King's death, the flames began to consume the entire Netherworld army.
The people on the city walls cheered, as this was a hard-won victory for them.
It was the only victory they had ever experienced since their birth.
Subsequently, they knelt before Yun Fan to express their gratitude.
Yun Fan didn't say much, as he noticed something highly suspicious. Although the Netherworld Ghost King and his army were dead, the aura of death had not dissipated. This was completely illogical.
"What's going on?"
Yun Fan's brow furrowed with confusion, but he knew that at this moment, passing was the most important thing.
Furthermore, it was frustrating that there were no rewards at all, which left him no time to linger and investigate.
He then asked the old man, "The Netherworld Ghost King is dead, how do we leave this place?"
"Mighty one, I know where to leave. Follow me!"
The old man led the way, and Yun Fan followed.
Soon, they arrived at a certain location. Yun Fan had expected this to be the exit, but instead, the further they walked, the heavier the aura of death became.
It was even more potent than the death energy of the Netherworld Ghost King. Yun Fan understood what this meant.
He stopped in his tracks.
"Mighty one, why aren't you moving?"
The old man asked Yun Fan.
Yun Fan replied, "Netherworld Ghost King, you are truly cunning. You almost deceived me too!"
The old man's expression immediately changed. "How did you know?"
At this point, he no longer bothered to conceal himself, as Yun Fan had already seen through him. There was no point in hiding.
Yun Fan continued, "I didn't know at first, but the Netherworld Ghost King was so weak, it couldn't have been him! You brought me to this place, and the death energy grew heavier. Therefore, I concluded that you are the Netherworld Ghost King!"
"You concluded that based on this? Isn't that too hasty?"
The Netherworld Ghost King looked at Yun Fan playfully.
Yun Fan responded, "It's not hasty at all. In fact, from the moment I arrived, I fell into your trap. This continent has no living beings; it was just the overwhelming death aura that affected my judgment!"
"Clever!"
The Netherworld Ghost King praised Yun Fan, "I must say, you are very intelligent. I don't know what means you used to kill my subordinate generals, but now, you are my prey!"
Don't ask why he didn't recognize someone from ten thousand years ago with similar attributes to Yun Fan.
That individual had not come from the east ten thousand years ago, but from one of the other three directions. Therefore, he was quite unfamiliar with Yun Fan's power.
Yun Fan listened and said, "That's not necessarily true. I just want to know how many succeeded. Can you tell me now!"
"A total of over four hundred people, with less than fifty successfully leaving. Two of them left through their own strength, while the rest barely managed to escape with the help of artifacts!"
Upon hearing this, Yun Fan's expression changed drastically. It seemed this trial had a very high attrition rate.
Yun Fan then asked, "I'd like to know how they escaped?"
"You ask too many questions. I don't wish to answer you. After all, you are merely prey; there's no need for you to know so much!"
The next moment, the Netherworld Ghost King revealed his strength: the sixth stage of Immortal Emperor. No wonder he was so arrogant.
Yun Fan stated, "The sixth stage, now that has some value for transformation!"
"What did you say?"
The Netherworld Ghost King glared at Yun Fan chillingly.
Yun Fan replied, "Nothing. In fact, I already know how they escaped. I can leave by defeating you!"
"Yes, that's true, but you are not yet qualified to defeat me!"
However, as soon as the Netherworld Ghost King finished speaking, Yun Fan launched a swift attack, striking him. Flames began to erupt from his body.
Without hesitation, the Netherworld Ghost King abandoned his current form and fled.
As he fled, he roared with laughter at Yun Fan, "Hahahaha, boy, this is my Ghost Domain. You cannot leave! Stop struggling!"
"Although your power can restrain me, I can slowly wear you down without fighting."
With that, his presence vanished.
Subsequently, the people who had been kneeling before Yun Fan transformed into vengeful spirits and charged at him.
Annoyed, Yun Fan unleashed a single strike, and these vengeful spirits vanished into nothingness.
"Trash!"
Yun Fan scornfully taunted, then continued deeper into the Ghost Domain, which resembled a labyrinth with no apparent exit.
Moreover, at this moment, countless auras of death descended, attempting to corrode his body, but they had no effect on Yun Fan.
Thus, these death energies were unable to infiltrate Yun Fan's body.
"Damn it, if this continues, he'll escape!"
The Netherworld Ghost King, hidden in the shadows, was displeased. He had a strong interest in Yun Fan, his prey, and he had suffered significant losses because of him.
He absolutely could not let Yun Fan leave alive.
Therefore, the next moment, he thought of a plan.
He released a prodigy who had fallen unconscious. He hadn't had time to refine them all, as this time's harvest had been too great.
So, by now, he had only refined half of the hundreds of prodigies. He would refine the rest after he annihilated Yun Fan.
To prevent any unforeseen circumstances, he released another one.
After walking for a long time, Yun Fan spotted two prodigies.
He was about to attack, but upon seeing that these two, a man and a woman, were not undead, Yun Fan held back.
"Fellow Daoist! How are you here?"
Yun Fan asked, "Didn't you all die?"
The male prodigy quickly replied, "Fellow Daoist, many are not dead, but were sealed by the Netherworld Ghost King!"
"However, the final outcome is still grim; it's unlikely we can escape death!"
"Yes!"
The female prodigy, whose appearance was quite acceptable, quickly added.
Hearing this, Yun Fan directly questioned, "Since they are all sealed, how are you two able to appear here?"
The male prodigy quickly explained, "Because of your appearance, you awakened us!"
"Mm!"
The female prodigy nodded eagerly.
At this, the two pleaded with Yun Fan, "Fellow Daoist, can we form an alliance with you and leave together?"
However, Yun Fan replied, "Not interested!"
"Fellow Daoist, we want to live. Please have pity on us!"
The two prodigies knelt and begged Yun Fan.
Yun Fan then said, "I am walking ahead. You can completely follow me."
"Thank you, Fellow Daoist!"
The two prodigies were overjoyed and quickly followed Yun Fan's footsteps.
But after less than a day of walking, the female prodigy quietly approached Yun Fan.
"What do you want to do?"
Yun Fan asked, confused.
She shyly replied, "Fellow Daoist, I know you are extraordinary. If you can take me out of this wretched place, I will repay you with my body."
"Not interested!"
Yun Fan stated bluntly.
However, the female prodigy did not give up. "Fellow Daoist, I also know a secret. The Ghost King actually wanted us to follow you. He wants to deal with you, but he threatened us not to speak of it. Be careful yourself!"
"Mm!"
Yun Fan nodded. The female prodigy was unsure of Yun Fan's true feelings, but as long as she could leave, that was all that mattered. If Yun Fan thought she was a burden and abandoned her, what would happen then?
However, at this moment, Yun Fan revealed a cold smile. "Playing mind games with me? You are too inexperienced! Netherworld Ghost King!"
