When 10,000 Eyed Taotie appeared, Spectral Fire Phoenix's vision was completely obscured by Bloodsucking Scourge's heavenly rule power. She could not see him at all.

However, she felt an awesome presence nearby, and immediately guessed what was happening. She knew that she was in grave danger, and immediately fled as quickly as she could without hesitation.

But 10,000 Eyed Taotie was here now. How could he possibly let her escape.

As he arrived, all of the eyes on his body started to emit a ghostly light. This was the 10,000 Eyes Lifebreaker, which shot out light from all 10,000 eyes to control one's opponent.

Any of a lower cultivation realm than 10,000 Eyed Taotie would be powerless before its control. At that time, Spectral Fire Phoenix could only sit passively. They would be able to ask her anything. If 10,000 Eyed Taotie's skill took effect, Underworld Dragon's Den's secrets would be laid bare.

Of course, Full Moon of Nanshan nearby would also be able to hear it all, and then pass it on to Wu Yu, who would be able to determine if the Ancient Demon Dragon Perpetual Devourer immortal design was going to harm Jiu Ying, as well as his current situation. The two might very well be connected.

The ghostly light streamed from all the eyes on 10,000 Eyed Taotie, capturing Spectral Fire Phoenix within. Her will began to ebb away, her resistance growing weaker. In no time at all, Spectral Fire Phoenix would be completely helpless, under the complete control of 10,000 Eyed Taotie.

Just at this time, another powerful force appeared. It was a sinister and violent force that descended from the skies, scattering 10,000 Eyed Taotie's ghostly light and breaking Spectral Fire Phoenix free.

10,000 Eyed Taotie whirled around in fury, his plans spoiled on the verge of success. He found himself facing nine heads, all joined to a gigantic ebony dragon body. It was Diabolical Dragon King himself!

Diabolical Dragon King had appeared at this critical moment, smashing apart 10,000 Eyes Lifebreaker and wresting Spectral Fire Phoenix away from his control.

Just like that, Underworld Dragon's Den's secrets would remain safe for a bit longer. However, now the two 8-heavens demon kings were face to face. Their fighting power was among the finest, these two leaders of superbly powerful factions in Demon Immortal Realm.

From the get go, Diabolical Dragon King crushed 10,000 Eyed Taotie down. After all, he had been preoccupied with the 10,000 Eyes Lifebreaker Mystique. 

It was also because he had been completely unprepared. If he knew that Diabolical Dragon King was nearby, he would definitely have guarded himself better. He had been completely outsmarted by Diabolical Dragon King this time.

Bloodsucking Scourge had likely found Spectral Fire Phoenix because she had purposely revealed herself, luring Bloodsucking Scourge here so that Diabolical Dragon King could deal with Bloodsucking Scourge.

Ironically, both had come with the same plan, and so the two 8-heavens demon kings had now come face to face.

"Same old, Taotie you freak. Seems like you haven't improved one bit. All you know how to do is attack the juniors."

Diabolical Dragon King sneered as he mocked 10,000 Eyed Taotie.

10,000 Eyed Taotie was frustrated that his 10,000 Eyes Lifebreaker Mystique had been interrupted, and he immediately flew into a rage at these mocking words. He roared: "You nine-headed worm, you're no better. Get right to it. What on earth is that immortal design that you're fooling around with?"

"Nothing to do with this, is it? Of course I have my own plans within my territory!"

Diabolical Dragon King harrumphed. He obviously would not reveal his secret so easily.

After all, it was very important to him, and would closely affect his cultivation improvement in the future.

"Best be more honest. I'm just worried that you don't know what you're doing. You might mess things up for all of us. And that is responsibility you can't bear."

10,000 Eyed Taotie's cold accusation hit back strongly at Diabolical Dragon King. He might have just had his Mystique dispersed, but he was still capable of standing toe to toe against him.

Both were among the strongest in the Demon Immortal Realm, at the eighth tier of the Great Void Demon Immortal Realm.

They faced each other in a stalemate. They could not fight, for risk of alerting the entire Demon Immortal Realm. But 10,000 Eyed Taotie was not willing to give up, continuing to interrogate Diabolical Dragon King about the immortal design in Underworld Dragon's Den.

As for Diabolical Dragon King, he refused to tell. And so they continued to square off, neither daring to fight, neither willing to retreat.

They could not keep this up forever. Finally, Diabolical Dragon King stirred. He had already rescued Spectral Fire Phoenix. "Scram back to your place then. Don't come here meddling and trespassing. Otherwise I would have to really show you my strength. Don't' want to fight, do you?"

10,000 Eyed Taotie, as resentful as he was at being threatened and slightful thus, understood where Diabolical Dragon King was coming from.

It was pointless to keep this stalemate up. Besides, Diabolical Dragon King's territory meant that his reinforcements from Fiendish Underworld Metropolis were close by, and he would be able to put up numbers that 10,000 Eyed Taotie and Bloodsucking Scourge together could not deal with.

Besides, 10,000 Demons Ancient Lands was just a tad weaker than Fiendish Underworld Metropolis overall.

Therefore, 10,000 Eyed Taotie knew that the game was up. There was no need to continue the head-to-head, because he would be the one to come off worse out of it.

Therefore he called to Bloodsucking Scourge, and they left with a parting shot: "Hope you know what you're doing!"

He implied that he would not let this matter go.

Even if he could not take Diabolical Dragon King on directly, he could continue to unleash Bloodsucking Scourge to snoop around Fiendish Underworld Metropolis for opportunities, creating chaos and disorder. That was no loss to 10,000 Eyed Taotie. The ball was in Diabolical Dragon King's court.

For each day that Bloodsucking Scourge did not leave, for each day that Fiendish Underworld Metropolis continued to be insecure, it meant another day that the Diabolical Dragon King did not dare to act. Delaying time was to 10,000 Eyed Taotie's advantage.

Any disadvantage for a foe was an advantage for oneself!

10,000 Eyed Taotie had already seen the anger and frustration in Diabolical Dragon King's eyes. If he were continually interrupted, he would be forced to take drastic action sooner or later.

However, 10,000 Eyed Taotie was unafraid. He would be fine - Diabolical Dragon King would not dare to declare open war against 10,000 Demons Ancient Lands either.

That was his strategy. Delay time, and see who ran out of patience first!

After 10,000 Eyed Taotie left, he ordered Bloodsucking Scourge to continue lurking near Fiendish Underworld Metropolis, looking for clues and opportunities alike. The more chaos, the better.

As for 10,000 Eyed Taotie himself, he would leave. As an 8-heavens demon king, his aura was too strong, and he would definitely invite unwanted and unnecessary attention if he lingered.

Bloodsucking Scourge had a near-invisible profile, and was most suited for this sort of reconnaissance work. If he could get information, that would be ideal. If not, then he would content himself with slowing down Diabolical Dragon King's progress.

No matter what, 10,000 Eyed Taotie had no doubt that he was up to no good.

Otherwise, why hide things so blatantly?

The clash between the two 8-heavens demon kings ended just like that. Both sides had thrown fighting words, but the overall situation had not changed much. Spectral Fire Phoenix had recovered from her reverie, and then Diabolical Dragon King took her away, clearly returning to Underworld Dragon's Den.

Full Moon of Nanshan continued to stick to him, his Gone from the Skies Mystique completely erasing his signature. Nobody could sense him, not even the two 8-heavens demon kings. Even if he were right under their noses.

Full Moon of Nanshan did not linger as 10,000 Eyed Taotie left. He continued to tail Bloodsucking Scourge.

Full Moon of Nanshan and Wu Yu were on the same page regarding this turn of events. Bloodsucking Scourge was the key to saving Jiu Ying. He had to be watched closely. As for 10,000 Eyed Taotie, it would definitely be a little more dangerous to follow him, and besides, he could not act personally in this.

At most, he could delegate Bloodsucking Scourge to work, and so following him would suffice.

As for Wu Yu, he soon heard from Full Moon of Nanshan regarding the meeting between the two. This was not a good sign for him. If he did not find any opportunity this time, who knew when the next would present itself.

Fortunately, 10,000 Eyed Taotie had yet to give up, continuing to send Bloodsucking Scourge forth to disrupt and monitor things. This meant that Wu Yu still had a chance!

10,000 Eyed Taotie had called it well. Diabolical Dragon King, preoccupied, would definitely not engage in open warfare with him. That was why Bloodsucking Scourge could work magic. Given his abilities, he would not be able to be taken down without raising a huge fuss.

Therefore, Bloodsucking Scourge was the best choice for this situation.

Diabolical Dragon King had taken Spectral Fire Phoenix back with him. The other two 7-heavens demon kings Nightmare Ink Qilin and Darkstrife Beast would not linger outside either.

They had searched for Crimson Moon Kunpeng for a long time and not found anything. He was either already long gone, or so well hidden that they could not appear. If that was the case, then there was little worry that he would be leaking news of Ancient Demon Dragon Perpetual Devourer immortal design.
