Back in Crimson Blood Demon Palace, Wu Yu laughed ironically. To think that he would change identities and end up back in the same place.

Primitive Demon King was not like Kunpeng Demon King, who had been watched like a hawk after the murder of Green Fire Demon King. He had also been ostracized by the other demon kings, and hence restricted in his movements.

However, he was still a newcomer, and so would probably receive some extra scrutiny.

Primitive Demon King did not know the demon kings of Underworld Dragon's Den either, and so could not easily get the information he wanted.

As a 6-heavens demon king, he could bully the other 5-heavens demon kings, as long as he did not go overboard. But these 5-heavens demon kings might not even know as much as he did, and there was no need to ask them anything.

He now had control of Crimson Blood Demon Palace, and did not plan to go out either. He would conduct his surveillance more surreptitiously.

In less than three days after Wu Yu had infiltrated back in as Primitive Demon King, there was another disturbance at Underworld Dragon's Den. Clearly, Diabolical Dragon King was worried that Crimson Moon Kunpeng had escaped out to leak news on the Ancient Demon Dragon Perpetual Devourer immortal design, and so mobilized all three 7-heavens demon kings to personally search.

If they found Crimson Moon Kunpeng, they would definitely kill him without hesitation!

The reason he sent out the 7-heavens demon kings was because Diabolical Dragon King was worried that Bloodsucking Scourge was in the vicinity. Anyone but a 7-heavens demon king would be in danger if found.

Even if they could not beat him, they could definitely stall him for a long time.

As Primitive Demon King, Wu Yu immediately conveyed this news to Bloodsucking Scourge after learning of it.

Bloodsucking Scourge would definitely capitalize on this opportunity. If he found a weakness, he would definitely jump on the opportunity to kill a 7-heavens demon king of Fiendish Underworld Metropolis. This would definitely hurt them overall, and might force some new information out of Diabolical Dragon King.

Full Moon of Nanshan had been tailing Bloodsucking Scourge all this time.

He saw that Bloodsucking Scourge immediately conveyed this information back to 10,000 Eyed Taotie.

Releasing the three 7-heavens demon kings was a godsend for 10,000 Demons Ancient Lands. If they used this chance well, they could come out way ahead.

Bloodsucking Scourge intended to personally follow one 7-heavens demon king. If 10,000 Eyed Taotie personally came to subdue them, they might well be able to get information on the immortal design's secret.

10,000 Eyed Taotie was also very curious about this secret. The stirrings at Underworld Dragon's Den was making him sleep uneasy. If Diabolical Dragon King reached the ninth tier of the Great Void Demon Immortal Realm tomorrow and attacked him... the two had never gotten along well.

And if 10,000 Eyed Taotie could but learn his secret, then he might be able to foil his plans and turn the tables back on Diabolical Dragon King.

As for Wu Yu, as Primitive Demon King, he could orchestrate the whole thing. He was Primitive General, personally knighted by Bloodsucking Scourge himself. If Bloodsucking Scourge got any information, he definitely would pass it on. This could also be a chance for Wu Yu to gather intelligence on 10,000 Demons Ancient Lands.

As long as he could learn what the Diabolical Dragon King was up to, Wu Yu could ascertain whether the Ancient Demon Dragon Perpetual Devourer immortal design was harmful to Jiu Ying, and perhaps shed light on his current state.

Recalling Jiu Ying in that blank state made Wu Yu nervous. But this matter could not be rushed. He was still building up the opportunity.

On the tail, Full Moon of Nanshan spotted Bloodsucking Scourge hunting for trails of the three 7-heavens demon kings near Fiendish Underworld Metropolis.

Bloodsucking Scourge had rather fantastic Mystiques, as well as some sort of tracking heavenly rule power. After half a month, he finally found Spectral Fire Phoenix near a volcano!

This volcano was even hotter than a usual volcano, and at least the size of two or three lesser realms. Its temperature was so high that only 5-heavens demon kings and above could even get near.

Spectral Fire Phoenix guessed that Crimson Moon Kunpeng must have gone on the run, fleeing to a remote place to hide himself. Therefore, this Xingyan Volcano was a possible place for him to hide in.

Firstly, there were very few people who would come here. Secondly, if they fought, Crimson Moon Kunpeng's affinity could flourish in such an environment.

Spectral Fire Phoenix's reasoning made sense. Unfortunately, Crimson Moon Kunpeng was long dead by Wu Yu's hand, and devoured so cleanly that not even a bone was left. Therefore, no matter how sharp her guesses, how brilliant her reasoning, there was no chance that she could find Crimson Moon Kunpeng.

Bloodsucking Scourge was well hidden in the vicinity, watching Spectral Fire Phoenix's every move at Xingyan Volcano.

Xingyan Volcano's fiery heat did not affect Spectral Fire Phoenix much. Therefore, she was able to constantly fly around within, searching for traces of Crimson Moon Kunpeng.

Bloodsucking Scourge's camouflage powers were quite respectable. He was already very near to Spectral Fire Phoenix, and still undetected. At the same time, Bloodsucking Scourge had also conveyed her location to 10,000 Eyed Taotie.

When Taotie Demon King arrived, Spectral Fire Phoenix would be cornered good and proper. There was little chance that she could escape from a 8-heavens demon king.

As good as Bloodsucking Scourge's concealment technique was, Full Moon of Nanshan's was better. He had gone completely undetected by either party in all this time, and not even Diabolical Dragon King or Taotie Demon King would be able to sense him.

Gone from the Skies was the ultimate technique from Marshal Tian Peng's legacy. He had already cultivated it to the ninth tier. Unless the opponent was at the eternal demon emperor realm, he could not be found.

Wu Yu, who had just joined Underworld Dragon's Den as Primitive Demon King, would definitely not run around and draw suspicion.

He left everything at Xingyan Volcano to Full Moon of Nanshan.

Now that 10,000 Eyed Taotie had received Bloodsucking Scourge's information and knew of Spectral Fire Phoenix's location, he should be speeding over. If Spectral Fire Phoenix was in the dark up till the last moment, she would be in deep trouble indeed.

Although Spectral Fire Phoenix was able to sense danger to some extent, but the profound heat in Xingyan Volcano dulled the demon kings' senses. Even if a strong being was approaching, they might not be able to sense it immediately.

10,000 Eyed Taotie drew ever closer, and Bloodsucking Scourge's tiny body trembled with anticipation. Full Moon of Nanshan saw the murderous intent in his eyes. He could not wait to attack Spectral Fire Phoenix.

Meanwhile, Spectral Fire Phoenix was getting a little frustrated within Xingyan Volcano. She had not seen hide or hair of Crimson Moon Kunpeng, nor sensed his presence.

Originally, she felt that Crimson Moon Kunpeng was almost definitely here, but now it seemed like her guess was wrong. It was ridiculous that someone of her ability could not find Crimson Moon Kunpeng. If the other two 7-heavens demon kings also came up empty-handed, Diabolical Dragon King would throw a fit.

But since Xingyan Volcano was clear, there was no reason for her to linger.

After making one final round, Spectral Fire Phoenix readied to leave, albeit a little irritated. Her black flames cloaking her, she took flight from the huge volcano.

But just as she flew up from the volcano, an unexpected figure barred her way.

"Bloodsucking Scourge?"

Spectral Fire Phoenix saw a menacing speck in her way. She sneered. Seemed like Diabolical Dragon King's calculations had been right on point.

If 6-heavens demon kings came out to hunt Crimson Moon Kunpeng, they would probably be taken in by Bloodsucking Scourge.

But she, the Spectral Fire Phoenix, was no one to mess with. Not even the Bloodsucking Scourge could take her down with any ease. She even knew that such a possibility might occur, and had prepared well before hand. She should be able to get free expediently.

"Bloodsucking Scourge, what are you plotting? Get out of my way immediately, lest I assume the worst of you!"

Spectral Fire Phoenix said contemptuously, her words laced with the hint of a threat.

But Bloodsucking Scourge had come exactly to find her. Besides, this was the time to strike, and he had no spare energy to waste talking to her. He immediately morphed into a mist of blood, and came at her with his heavenly rule power.

In the next moment, the mist of blood covered the sky, enclosing Spectral Fire Phoenix within. The mist further numbed a demon king's senses.

Just as Bloodsucking Scourge made his move, a fearsome beast landed beside him. This was the reason for Bloodsucking Scourge's courage - 10,000 Eyed Taotie!

This was a savage Taotie beast. It had the body of a goat and the face of a human. Its eyes gleamed with malice, and there was a nightmarish mouth on the chest under its brain. The mouth was half as big as its body, and arrayed with teeth, stained a bloody red. He looked like he had just eaten.

The mouth was scary enough to keep one awake at night. He was also covered in eyes, a total of 10,000 all over his body. These eyes were gross flesh vortexes. One felt like one's energy was being sapped just by gazing at them, mesmerized by the grotesque beast.

This was the 10,000 Demons Overlord of 10,000 Demons Ancient Lands, the 10,000 Eyed Taotie, Taotie Demon King!

With his appearance, Spectral Fire Phoenix was in deep trouble.
