Bloodsucking Scourge and 10,000 Eyed Taotie belonged to a faction called the 10,000 Demons Ancient Lands.

10,000 Eyed Taotie was the 10,000 Demons Overlord, while Bloodsucking Scourge was the Vampiric General. He was considered very strong within 10,000 Demons Ancient Lands, and one of 10,000 Eyed Taotie's best generals. 

Bloodsucking Scourge was indisputably strong. At least from what Wu Yu saw, this Bloodsucking Scourge was definitely at least a match for Spectral Fire Phoenix, Nightmare Ink Qilin, or Darkstrife Beast. More importantly, his small size meant that he could move undetected, striking with the element of surprise.

Overall, 10,000 Demons Ancient Lands was more or less equal to Fiendish Underworld Metropolis in terms of power.

If Wu Yu could join Bloodsucking Scourge's 10,000 Demons Ancient Lands, he could not only go to cause havoc in Underworld Dragon's Den, but also disrupt the progress of the Ancient Demon Dragon Perpetual Devourer immortal design.

Therefore, Wu Yu's eyes flicked up hopefully, beseeching Bloodsucking Scourge: "O great Vampiric General, how about allowing this Primitive Demon King to join the 10,000 Demons Ancient Lands? The humiliation by Diabolical Dragon King was too much. I can't stand it!"

Bloodsucking Scourge was already thinking of finding out what Diabolical Dragon King was up to. Now that Primitive Demon King was asking to join him, he was only too pleased to accept.

Bloodsucking Scourge did not have many subordinates. And now Primitive Demon King wanted to stand with him against Diabolical Dragon King - how could he refuse?

Therefore, Bloodsucking Scourge smiled genially: "10,000 Demons Ancient Lands welcomes you! In these parts, Primitive Demon King has quite a reputation as well. Since that's the case, I will dub you Primitive General. Any objections?"

Hearing this, Wu Yu showed great pleasure, as he said: "Many thanks to the Vampiric General for his grace! I, Primitive Gold Devouring Rat, will definitely work my guts out for  the 10,000 Demons Ancient Lands!"

"Forget about that for now. There is something important which must be dealt with. Diabolical Dragon King is up to something. Based on what you said, they're building some elite immortal design in Underworld Dragon's Den, and it's covering the whole Underworld Dragon's Den with dark dragon silhouettes?!"

Bloodsucking Scourge spoke in a hushed voice to Primitive Demon King. "If that's the case, Primitive General, then you will head to Underworld Dragon's Den again. This time, be sincere, and do your best to enter Underworld Dragon's Den. This time, you must find out what Diabolical Dragon King is up to. If you can give an accurate answer, your hard work will be personally rewarded by King Taotie himself!"

"Really?!"

Wu Yu immediately feigned enthusiasm. He looked thrilled. 10,000 Eyed Taotie was an 8-heavens demon king, who was much stronger than Primitive Demon King.

This meant that a present from 10,000 Eyed Taotie might well be an elevation into the core of the 10,000 Demons Ancient Lands.

"Go and do your best work. We, the 10,000 Demons Ancient Lands, will support you."

Bloodsucking Scourge smiled broadly: "Even if you are but a new initiate, if you do good work on our behalf, you will be one of us, and enjoy the benefits that we do! Even if we get an eternal demon emperor corpse, we will also leave you a piece!"

Of course, Wu Yu did not believe these honeyed words. It was all too apparent that Bloodsucking Scourge was simply playing him. But he was not Primitive Demon King. Under such circumstances, any excuse to go and f*ck with Underworld Dragon's Den was a good thing indeed.

Even if Bloodsucking Scourge was only manipulating him, Wu Yu did not mind. Following Bloodsucking Scourge was all good for now.

"Vampiric General, do not worry. I will go immediately, and do my best to get information!" Wu Yu said, immediately fired up. He bid farewell to Bloodsucking Scourge, and turned, flying back to Fiendish Underworld Metropolis.

Originally, Wu Yu just wanted to lure Bloodsucking Scourge away so he could devour him. But now that no such opportunity presented itself, he retreated safely. For now, he would fight by his side. If he could tap on the power of the 10,000 Demons Ancient Lands, he could cause even more confusion in Underworld Dragon's Den.

Good enough for Wu Yu!

As for Bloodsucking Scourge, he naturally would follow Wu Yu. This Primitive Demon King had just entered 10,000 Demons Ancient Lands. Naturally, Bloodsucking Scourge would not be too reassured, and would continue to monitor him.

Wu Yu was unafraid of his monitoring. On the contrary, he was afraid that he would not come. Each day that Bloodsucking Scourge was in Underworld Dragon's Den meant a day that Diabolical Dragon King would not dare to continue work on the Ancient Demon Dragon Perpetual Devourer immortal design.

Full Moon of Nanshan naturally would continue to stalk Bloodsucking Scourge, and pass on information to Wu Yu. This was an ideal situation for them.

Bloodsucking Scourge was someone important in 10,000 Demons Ancient Lands. As long as he could stir something, anything, it would be a huge pain in the neck for Diabolical Dragon King.

Before long, Wu Yu had returned to Fiendish Underworld Metropolis.

He approached Underworld Dragon's Den, and adopted a very sincere pose, shouting: "Mighty Diabolical Dragon King! The humble Primitive Gold Devouring Rat begs an audience. I hope that I may join the Fiendish Underworld Metropolis. I come in earnestness and goodwill. I hope that you can grant my wish!"

"Before, I was ignorant to reject the Diabolical Dragon King's invitation. I hope that the great dragon king can give me a chance to join Underworld Dragon's Den. I will definitely live and die for Underworld Dragon's Den, and go through brimstone and hellfire!"

Sincere vow followed sincere vow, rolling off Wu Yu's tongue and echoing throughout Fiendish Underworld Metropolis.

Many were moved by his honest attitude, and felt that this Primitive Gold Devouring Rat was quite a sincere one. Ordinarily, there should be no reason for the Diabolical Dragon King to reject him.

However, reality was often disappointing.

It was a critical period, and the Ancient Demon Dragon Perpetual Devourer immortal design halfway done. To suddenly be interrupted, Diabolical Dragon King was reluctant for any other external factors to disturb it. More people, more risk to exposure.

After all, this Primitive Gold Devouring Rat had never seemed particularly trustworthy to Diabolical Dragon King. There was no need to take this risk.

Finally, after Wu Yu had shouted for a few days, Spectral Fire Phoenix came flying out from Underworld Dragon's Den. Her face was cold: "What manner of demonic gnat is this, shrieking and squawking at Underworld Dragon's Den. Begone with you! Before I make it so that you can't even flee!"

Spectral Fire Phoenix did not seem to be in a good mood. Perhaps she was feeling off-kilter now that the Ancient Demon Dragon Perpetual Devourer immortal design progress had ground to a halt.

She showed Primitive Demon King not one iota of goodwill at all, immediately chasing him off.

Of course, Wu Yu would not give up so easily. Spectral Fire Phoenix was but one member in the whole of Underworld Dragon's Den. The one he really needed to convince was Diabolical Dragon King. If he succeeded, entering Underworld Dragon's Den would be easy.

Therefore, he continued to plead: "Magnificent Spectral Fire, I am here sincerely trying to join the Underworld Dragon's Den. Why will you not trust me this once?"

His voice rang with bare truth in them, and moved many within Fiendish Underworld Metropolis.

A pity that Spectral Fire Phoenix did not even bother to heed Primitive Demon King.

No matter how much Wu Yu begged, she had no intention of letting Wu Yu into Underworld Dragon's Den.

This made Wu Yu very discouraged. The identity of Primitive Demon King was still too difficult to use. Mainly because he had always sbeen a slimy character, and his crafty reputation won him no trust at all.

Who did not know the cunning name of the Primitive Demon King?

This only made it all the more difficult for Wu Yu to enter Underworld Dragon's Den.

Wu Yu was troubled. This Primitive Demon King was truly a failure at being a demon. If he had known, he would have changed an identity, and the situation might be a thousand times better......

Just as Wu Yu clung desperately to his last speck of hipe, suddenly someone came to report to Spectral Fire Phoenix.

"Spectral Fire Demon King! We have a problem! Crimson Moon Kunpeng has actually fled Underworld Dragon's Den. We have searched the entire Underworld Dragon's Den, and have not found him. The dragon king himself is in a mad rage. Is there no way to deal with this?"

That person had rushed up breathless to tell Spectral Fire Phoenix. This piece of news lit up Wu Yu's eyes.

Another chance.

Fashioning the Ancient Demon Dragon Perpetual Devourer immortal design had already been a tedious process to begin with. If the number of people continued to lessen, the time taken would continue to increase correspondingly.

They had actually discovered Crimson Moon Kunpeng's disappearance. This meant that they might be recruiting to fill in his gap. If not, the Ancient Demon Dragon Perpetual Devourer immortal design could not possibly be completed on time.

Spectral Fire Phoenix snorted. "Crimson Moon Kunpeng? That spineless bastard. He was probably afraid that his own fashioning speed would be slowest, and so made his escape early. He actually dared to defy the dragon king's order. He's asking to be killed!"

"What do we do now?"

The person asked.

Spectral Fire Phoenix smirked. "No matter. One goes out, bring one in to fill the gap. Primitive Gold Devouring Rat, we will reluctantly approve your membership. But you will have to acquit yourself well. If we are displeased with your work, we will chase you out, and you had best not show your face at Underworld Dragon's Den ever again!"

She was giving Wu Yu some pressure first. However, she definitely would not tell him about the immortal design straight away.

To Spectral Fire Phoenix, she was simply trying to keep the Ancient Demon Dragon Perpetual Devourer immortal design's construction on schedule. She did not care who joined, as long as it was not the enemy.

And the Primitive Demon King was not an enemy, she thought.

Primitive Demon King had always been a neutral 6-heavens demon king. If he joined them, he would contribute greatly. If the Diabolical Dragon King could use him, why not include him in Underworld Dragon's Den?

"Follow me. We go to Crimson Moon Kunpeng's residence. Crimson Blood Demon Palace is yours, from now on."

Spectral Fire Phoenix led the way, bringing Wu Yu into Underworld Dragon's Den. He returned to Crimson Blood Demon Palace again, but now in a different identity. He was no longer Kunpeng Demon King, but Primitive Demon King.
