The idea that Bloodsucking Scourge and Heaven Devouring Titanic Beast was the same individual never crossed the Diabolical Dragon King's mind.

He could only suspect that the Heaven Devouring Titanic Beast had snuck in with the Bloodsucking Scourge to cause trouble, and that the Heaven Devouring Titanic Beast was probably one of the 10,000 Eyed Taotie's people. At this point, hatred towards the 10,000 Eyed Taotie had built up. If not for the urgent situation, the Diabolical Dragon King would have gone straight to the 10,000 Eyed Taotie and fight him.

It was a pity that he must settle the situation in the Underworld Dragon's Den first. Otherwise, he would suffer greater loss by allowing Bloodsucking Scourge to continue his rampage. He would need many years to recoup his losses.

And to Wu Yu, the failed attack on the Darkstrife Beast this time meant that it would be more difficult to find another opportunity for ambush in future.

Obviously after experiencing the attack, the other party would be alerted and be kept on their toes. He would not only be wary of Bloodsucking Scourge, his current identity, but even more so of his other identity, the Heaven Devouring Titanic Beast. It would be diffcult to catch him off guard and slay him now.

This was not an optimistic situation for Wu Yu.

Besides, the other party could guess his movements. If he continued to destroy the design base of the Ancient Demon Dragon Perpetual Devourer immortal design, the other party would be able to guess his next destination and block him.

Wu Yu was now forced into a passive situation.

After all, most of the immortal design's foundation had already been destroyed by Wu Yu. The remaining few immortal design design bases were at fixed locations. If Wu Yu wanted to destroy all of them, he would definitely land into the other party's ambush.

All the other party had to do now was to wait for Wu Yu to show up.

As long as the Ancient Demon Dragon Perpetual Devourer immortal design was not entirely destroyed, the other party had nothing much to worry about.

Just as Wu Yu was hesitating on his next step, he received news as the Bloodsucking Scourge. 10,000 Eyed Taotie had arrived. He was now outside the Fiendish Underworld Metropolis and wanted an update on the current situation.

Wu Yu thought about it. Since he had no way of continuing his plan, he decided to meet the 10,000 Eyed Taotie first to update him on the situation. Perhaps the 10,000 Eyed Taotie had some ideas on what to do next.

After all this 10,000 Eyed Taotie was like the Diabolical Dragon King. They were both 8-heavens demon kings. Even if they started fighting, they would be on par. Wu Yu would benefit if the two demon kings were distracted with each other.

Very quickly, Wu Yu quietly left the Fiendish Underworld Metropolis and appeared in the vast mountains outside.

Wu Yu appeared outside as the Bloodsucking Scourge in the form of a crimson mosquito. 10,000 Eyed Taotie was there in his terrifying human-faced, goat-body form, with a huge horrifying mouth embedded in his chest. He was radiating a nightmarish aura.

This was one of the top demon immortals in the Demon Immortal Realm, the 10,000 Eyed Taotie, the Taotie Demon King!

This was the first time Wu Yu had seen this demon king. However, based on the Bloodsucking Scourge's memories, he had interacted countless times with the 10,000 Eyed Taotie. Hence, Wu Yu knew how to act and did not behave oddly.

"How's the situation inside?" 10,000 Eyed Taotie asked in a deep voice.

10,000 Eyed Taotie had met the Diabolical Dragon King before but could not do anything to him. However, now that the Bloodsucking Scourge had successfully stirred trouble in his city, the Diabolical Dragon King would have take a step back and negotiate with him. Otherwise, he was confident in stopping the Diabolical Dragon King from enjoying his treasure.

Wu Yu, as the Bloodsucking Scourge, quickly reported on the progress of his destruction. He also told the 10,000 Eyed Taotie that he had successfully injured the Darkstrife Beast badly by chance. It was a pity that he failed to slay him. Now the Diabolical Dragon King was furious and might start a war with the 10,000 Demons Ancient Lands.

Upon hearing, 10,000 Eyed Taotie scoffed: "Starting a war with the 10,000 Demons Ancient Lands? Does he really think that he can flatten us? You have done well. I did not expect for you to grow to this point, to even causing the Darkstrife Beast to be heavily injured. I'm heartened by your accomplishments. Now, let's see how the Diabolical Dragon King reacts. He better be frank. Otherwise, he will never get the opportunity to peacefully enjoy whatever treasure that he has gotten his hands on!"

He actually guessed that the Diabolical Dragon King's important treasure was probably related to the eternal demon emperor corpse. If it was an eternal demon emperor corpse, then he would have to eat it and spend time to absorb and digest it.

And he, the 10,000 Eyed Taotie, would never give the Diabolical Dragon King the time to do so.

They were thinking of that when a domineering pressure came from atop. It had originated from the Fiendish Underworld Metropolis. Closely followed was the Nine-Headed Diabolical Sable Dragon King who emerged from the dark clouds.

The Diabolical Dragon King was obscured within the dark clouds. He had finally decided to meet the 10,000 Eyed Taotie.

At this moment, the Diabolical Dragon King shouted out first: "Taotie! What do you want from creating these troubles? Are you truly asking for a fight?"

His voice was laced with anger. He was obviously losing control over his fury. Anyone could tell that he was extremely annoyed by the Bloodsucking Scourge's destructions.

10,000 Eyed Taotie was extremely pleased. It looked like one of his subordinates was as useful as three of Diabolical Dragon King's subordinates.

However, this was not the time to boast about his subordinate.

10,000 Eyed Taotie snorted and said coldly: "I know that you have landed yourself a treasure. If you share it with me, I shall stop stirring trouble in your city. I will not let anyone else learn of the treasure too. Otherwise, you can forget about peace. I will also spread news of your treasure. Then we shall see how long your Fiendish Underworld Metropolis can last!"

This was undoubtedly a huge threat to the Diabolical Dragon King.

After all, once news spread, 10,000 Demons Ancient Lands would no longer be the only party creating trouble in the Fiendish Underworld Metropolis. There would be countless demon kings from various territories flocking to his city. The news might even attract the attention of other 8-heavens demon kings!

After all, this treasure was something that even the Diabolical Dragon King had guarded so fervently. It would definitely attract the attention of the other 8-heavens demon kings.

While the Diabolical Dragon King possessed the treasure, it was Wu Yu who had told 10,000 Eyed Taotie about it. Even so, it was useless for Diabolical Dragon King to deny having it now. The 10,000 Eyed Taotie was sure that the Diabolical Dragon King was in possession of a great treasure. Otherwise, he would not be so cautious and even set up a strong great void immortal design in the Underworld Dragon's Den.

Hearing the 10,000 Eyed Taotie's threat, Diabolical Dragon King fell silent. Dark clouds rolled endlessly in the sky, hiding the Diabolical Dragon King.

Anyone could tell that the Diabolical Dragon King was torn between his options.

But he made his decision quickly: "Alright, come with me. I shall let you have a look. However, you cannot leak the news. I'm willing to share it with you this time. You are qualified to enjoy this treasure."

He said it calmly, yet not very willingly. He looked as though he was still worried that the 10,000 Eyed Taotie would announce to everyone news of the treasure.

However, Wu Yu was still very cautious. After all, Diabolical Dragon King did not seem like the type of demon king to willingly share his treasure. Most importantly, Wu Yu did not really believe that the Diabolical Dragon King had found some outstanding treasure. Even if it truly was a worthy treasure, it was likely to be the type that could not be shared.

After all, Jiu Ying seemed to be involved somehow. Jiu Ying was such a straight-laced demon. He might very well be related to the treasure. However, Wu Yu did not know the specifics. He had to follow the 10,000 Eyed Taotie and enter the Underworld Dragon's Den in order to seek out the truth.

To Wu Yu, regardless of whether this Diabolical Dragon King's invitation was sincere or not, it was a good opportunity for him.

If the two 8-heavens demon kings started to fight, then Wu Yu as the Bloodsucking Scourge could directly fight the 7-heavens demon kings within the Fiendish Underworld Metropolis. Darkstrife Beast, Spectral Fire Phoenix, and Nightmare Ink Qilin were no match for Wu Yu when separated. Wu Yu could even kill them quickly and devour them.

Wu Yu had no need to use another's identity once he found news of Jiu Ying. His actions would depend on the situation then.

10,000 Eyed Taotie nodded in satisfaction.

He agreed to follow the Diabolical Dragon King and enter the Underworld Dragon's Den to take a look at the situation.

On one hand, he was convinced that the Diabolical Dragon King had been threatened by him. On the other hand, his courage was boosted by his strength. Based on his current abilities, it would not be easy for the Diabolical Dragon King to ambush him. Hence, he was fearless.

10,000 Eyed Taotie acted as though he was invited as an honoured guest into the Fiendish Underworld Metropolis.

And Wu Yu followed him as the Bloodsucking Scourge.

Diabolical Dragon King was hidden among dark clouds and moved with the dark clouds into the Underworld Dragon's Den.

The 10,000 Eyed Taotie was on high alert as they moved. He was being careful in case of a sudden attack from the Diabolical Dragon King. Such level of precaution was necessary. Otherwise, Taotie Demon King would not be able to survive for so long in the Demon Immortal Realm.

However, once inside the Fiendish Underworld Metropolis, the risk of a threat was reduced. The Diabolical Dragon King was unlikely to act against them in the outskirts of his city.

The troubles that Wu Yu had previously stirred up in the Fiendish Underworld Metropolis as the Bloodsucking Scourge had been dealt with. Though those demon kings whom he had injured would require some time to recuperate. Now the entire Fiendish Underworld Metropolis seemed peaceful. The other demon kings did not dare to linger outside as well. Everyone knew clearly that the Fiendish Underworld Metropolis was no longer safe.

Very quickly, the Diabolical Dragon King brought 10,000 Eyed Taotie into the Underworld Dragon's Den.

10,000 Eyed Taotie could sense clearly signs of immortal design destruction in this region. These were the Bloodsucking Scourge's work. To him, the Bloodsucking Scourge had done well and actually managed to force Diabolical Dragon King into this position.

10,000 Eyed Taotie was even more cautious upon stepping into the Underworld Dragon's Den. After all, this was the nest of the Diabolical Dragon King. While 10,000 Eyed Taotie was not afraid of the Diabolical Dragon King, he would still be in trouble if he fell into the other party's trap.

Wu Yu followed 10,000 Eyed Taotie obediently and watched as the Diabolical Dragon King led 10,000 Eyed Taotie into the Diabolical Dragon Palace. He was a little surprised. Could it be that the Diabolical Dragon King was sincere in letting the 10,000 Eyed Taotie see his treasure?

This way, he might not be able to investigate news and secrets about Jiu Ying. Perhaps, the two demon kings might even cooperate!

Once the identity of the Bloodsucking Scourge was useless, and Wu Yu's true identity was exposed, the situation would only be worse... ...

However, just as Wu Yu was thinking of the worse-case scenario, something unforeseen happened. When 10,000 Eyed Taotie together with Diabolical Dragon King neared the Diabolical Dragon Palace, a huge shadow made of countless black dragons flew out, creating a domain which covered the 10,000 Eyed Taotie instantly.

This was actually a mini Ancient Demon Dragon Perpetual Devourer immortal design and it was activated suddenly, trapping the 10,000 Eyed Taotie within it!
