Wu Yu devoured the Bloodsucking Scourge and from this point onwards, Wu Yu could move around as Bloodsucking Scourge.

He had thought through thoroughly. Only with the standing and status of Bloodsucking Scourge could he create havoc in Fiendish Underworld Metropolis without constraints and create opportunities. After all, he had the 10,000 Eyed Taotie backing him.

Even if he did create a ruckus, 10,000 Eyed Taotie would protect him. This would be the plan for Wu Yu moving ahead.

This time, the group teamed up well to ambush and killed the Bloodsucking Scourge. The Bloodsucking Scourge couldn't send out an immortal message talisman in time, or more precisely, failed to convey the message out. With the World Discursor immortal design in place, the message was intercepted.

Therefore, no one else was aware Bloodsucking Scourge was now dead.

Wu Yu transformed into the scarlet mosquito. Although many would consider him as tiny, this was only relative to other powerful demon kings. The true form of the Bloodsucking Scourge was in fact much larger than a human. It was just that within the ranks of demon kings, he was indeed tiny in size. Therefore, his ability to conceal himself was also exceptional.

If he casually cast some concealment techniques, it would be hard even for demon kings like the Diabolical Dragon King to notice his existence.

Moving forward, it would be Wu Yu's time to perform!

"Big brother, what plans do you have in mind?" asked Ye Xixi in anticipation.

She was exhilarated about what's about to happen. If they were to upset the apple cart in the Fiendish Underworld Metropolis, Diabolical Dragon King would definitely be triggered. When the time came, they would have opportunities to exploit.

"I'll be relying on the abilities of the Bloodsucking Scourge to conceal myself at ease within Fiendish Underworld Metropolis. As long as it isn't Diabolical Dragon King, no one would be able to notice me. Once I'm discovered, I can still escape successfully with Somersault Cloud."

When he was done, he started rifing through the memories and techniques of the Bloodsucking Scourge. He realized Bloodsucking Scourge was indeed exceptional in concealment.

Moreover, the Blood Sink heavenly Rule and Blood Vortex heavenly rule were two relatively impressive killer techniques.

If they were used well, it would be sufficient to injure without killing. Wu Yu practiced several times to familiarize himself with the heavenly rule powers of the Bloodsucking Scourge so he could control them better.

Full Moon of Nanshan finally heaved a sigh of relief. However, he was missing the days when he was in the sky palaces. During those days, he would always be courting female immortals and had them accompanied him each day and night. Those were the great days and it's unfortunate that he is currently......

"Sigh. I could only face these ugly demons these days. How exhausting is this! Once we are done here, let's return to the sky palaces. I'll be able to continue with my Great Cause," remarked Full Moon of Nanshan emotionally.

Ye Xixi scorned disdainfully. She naturally knew what he meant by Great Cause. He's no different from a lecherous maniac!

Furthermore, if they were to return to the sky palaces now, only deaths awaited them. Full Moon of Nanshan was just grumbling and definitely wasn't serious with what he said. He just couldn't contain his restlessness without a lady accompanying him for a day.

As for Ye Xixi, she wasn't a lady in Full Moon of Nanshan's eyes. At most, she was a girl and not the type that he was fond of.

Wu Yu was practicing some heavenly rules as Bloodsucking Scourge. The most important heavenly rule powers of Bloodsucking Scourge were those such as Blood Shadow heavenly rule and Blood Evasion heavenly rule.

Blood Shadow heavenly rule was a concealment technique and would be greatly beneficial for Wu Yu. Blood Evasion heavenly rule was used for escaping that enabled him to transform into a stream of fresh blood, breakthrough the constraints of space and escaped. Nonetheless, this was definitely not comparable to Somersault Cloud.

Currently, there wasn't anyone, including all the demon kings of the Fiendish Underworld Metropolis and Underworld Dragon's Den, who knew about Wu Yu's existence. Somersault Cloud was undoubtedly the greatest secrets of all.

Even if he used it, he wouldn't be suspected. At the very most, others would just assume Bloodsucking Scourge had learnt a new Mystique.

After spending three months to familiarize himself with the techniques of the Bloodsucking Scourge, Wu Yu had perfected his mastery and could move as he wished. Before he set off, he knew he first had to communicate well with the 10,000 Eyed Taotie. 

He had to obtain initial approval from 10,000 Eyed Taotie if he wanted to wreck havoc in Fiendish Underworld Metropolis. Only then 10,000 Eyed Taotie would come to his aid if he got into trouble. Otherwise, in the face of Diabolical Dragon King, 10,000 Eyed Taotie might decide to give up on Bloodsucking Scourge.

Regardless, Wu Yu knew how he should frame the conversation.

He sent an immortal message talisman to 10,000 Eyed Taotie detailing, "Primitive Demon King has just gotten back. He found out Diabolical Dragon King is planning to lay an elite great void immortal design known as Ancient Demon Dragon Perpetual Devourer immortal design! The entire Underworld Dragon's Den is anxiously preparing for it so as to not let any information leak. There's at least a 90% chance that Diabolical Dragon King has gotten some prized treasure. If we aren't acting, the prized treasures would be monopolized by the Diabolical Dragon King!"

Using prized treasures to entice 10,000 Eyed Taotie was the most direct and effective way. After all, cultivation was still the most important to 10,000 Eyed Taotie. If Diabolical Dragon King really had something that he deemed as prized treasures, they would definitely be useful to 10,000 Eyed Taotie as well. Perhaps this was the opportunity to breakthrough to become an eternal demon emperor.

Therefore, 10,000 Eyed Taotie would definitely stay by the sideline.

"What is your plan?" 10,000 Eyed Taotie responded swiftly and it was clear he wanted Bloodsucking Scourge to formulate a plan.

The situation was tense and Bloodsucking Scourge was a general under 10,000 Eyed Taotie. The name of Vampiric General sent chills down the spines of countless demon immortals in 10,000 Demons Ancient Lands and 10,000 Eyed Taotie had seen him as his right-hand man.

Therefore, when 10,000 Eyed Taotie couldn't think of a plan, it was natural that he sought the opinions of Bloodsucking Scourge.

Wu Yu pondered before answering with immortal message talisman, "I'm planning to upset the apple cart in Fiendish Underworld Metropolis so Diabolical Dragon King can't have any peace of mind. Even if he did get some treasures, he wouldn't be able to enjoy them fully! In that case, my lord might have an opening to pillage those treasures. The key to my plan is to cause chaos in the Fiendish Underworld Metropolis. The greater the chaos, the more beneficial the circumstances would be for us."

"That's a good plan. Do as you say and update me." 10,000 Eyed Taotie replied and had clearly approved of Wu Yu's upcoming actions. Moreover, he was supportive of the plan.

In that case, if Wu Yu encountered any troubles, or more precisely, if Bloodsucking Scourge encountered any troubles, 10,000 Eyed Taotie definitely would not stay by the sidelines. Even if it was just for the prized treasures, 10,000 Eyed Taotie wouldn't let Diabolical Dragon King have his way.

After receiving 10,000 Eyed Taotie's approval, Wu Yu transformed into Bloodsucking Scourge and returned to the Fiendish Underworld Metropolis!

Currently, Underworld Dragon's Den had lost Crimson Moon Kunpeng and Green Fire Demon King while the newly joined Primitive Demon King had vanished. Therefore, the labor force in Underworld Dragon's Den had dropped substantially and the Ancient Demon Dragon Perpetual Devourer immortal design clearly wouldn't be completed in the near future.

Even though Wu Yu took several months off to deal with the Bloodsucking Scourge, the entire Underworld Dragon's Den was still quiet and serene. It was as though nothing had happened in the Underworld Dragon's Den.

The Ancient Demon Dragon Perpetual Devourer immortal design had been hidden away, clearly indicating the Diabolical Dragon King was relatively anxious. He didn't order the continuance of laying the immortal design in fear of complications. This made Wu Yu doubt his motives even further.

If he had to be so cautious, this was definitely an extremely important matter to the Diabolical Dragon King. However, with Bloodsucking Scourge creating havoc, he wouldn't have the peace of mind to continue.

Perhaps Diabolical Dragon King was thinking of ways to deal with Bloodsucking Scourge and 10,000 Eyed Taotie currently.

Unfortunately, Wu Yu was going to make the first move. Soon, Wu Yu would be causing chaos in the Fiendish Underworld Metropolis.

Before Diabolical Dragon King could think of a good solution, Wu Yu made the first move. Using the identity of Bloodsucking Scourge, he infiltrated into the Fiendish Underworld Metropolis.

He went to look for Caliginous Shadow Demon King that he met previously once he infiltrated into the Fiendish Underworld Metropolis.

Caliginous Shadow Demon King was a good friend of Primitive Demon King. He had been cultivating behind close doors on top of a mountain peak currently, trying to make his way to become a 5-heavens demon king. For him, the Fiendish Underworld Metropolis was an extremely safe place. All he had to do was to prepare sufficient tributes and he could cultivate in peace in this place. Moreover, the Fiendish Underworld qi was also robust in this place.

Therefore, this was a extremely great place for him. 

Therse were also the reasons why so many demon immortals would want to enter the Fiendish Underworld Metropolis. They were all seeking protection under the Diabolical Dragon King.

And now, Wu Yu disregarded Diabolical Dragon King's protection completely. He showed up before Caliginous Shadow Demon King and attacked him!

"Blood Vortex heavenly rule!"

Wu Yu had mastered this heavenly rule. After he showed up before Caliginous Shadow Demon King, he started attacking the demon king whose true form was a caliginous devilworm.

This was a type of gigantic devilworm that cultivated by devouring shadows. He exited his cultivation state in a hurry after he sensed unexpected attacks from the outside world. When he saw it was Bloodsucking Scourge that was attacking him, he was spooked.

Although he didn't understand why Bloodsucking Scourge would show up in the Fiendish Underworld Metropolis out of the blue and what gave him the guts to attack someone, Caliginous Shadow Demon King knew the infamy of Bloodsucking Scourge. This was an existence that would kill without battling an eyelid and cultivated through consuming the fresh blood of other demon immortals!

Could it be the Bloodsucking Scourge has set his eyes on him?

Caliginous Shadow Demon King tried to send an immortal message talisman to inform Diabolical Dragon King at the very first instant. However, to his horror, he saw the immortal message talisman stopped by the Bloodsucking Scourge. This was also because the difference between them was too great. Wu Yu didn't even have to use all his strength and yet he still had the time to intercept the immortal message talisman that the other party had tried sending. 

Therefore, there was no way for Caliginous Shadow Demon King to send any message out.

Wu Yu had not started and naturally wouldn't want Diabolical Dragon King to foil his plan. The Diabolical Dragon King should only be informed after Wu Yu had gotten his way. Only then could Wu Yu attract the most attention.

Otherwise, Diabolical Dragon King would probably not be distracted by such trivial matters.

When the Blood Vortex heavenly rule was unleashed, red blood fused into the vortex that had restricted Caliginous Shadow Demon King's movements. At the same time, fresh blood was constantly sucked out of Caliginous Shadow Demon King's body and into the blood vortex, strengthening the vortex in the process!
