Purple Beaked Roc Demon naturally wouldn't be willing to hand over the Heavenly Flames Demon Immortal Design Bell. To get it, two of his brothers sacrificed themselves. How could he just hand the item over willingly?

However, Green Fire Demon King wasn't intending to be reasonable and even gave him a ruthless beating. In the end, Purple Beaked Roc Demon King was severely injured and could only retrieve the Heavenly Flames Demon Immortal Design Bell for Green Fire Demon King.

Without a doubt, if Green Fire Demon King was to kill Purple Beaked Roc Demon King right now, it wouldn't be an issue. He could just report to the Diabolical Dragon King that the Purple Beaked Roc Demon King didn't follow the rules and was reluctant to pay tribute. As a result, he stepped in and killed Purple Beaked Roc Demon King.

Purple Beaked Roc Demon knew keeping his life was the most important thing. Therefore, he could only hand over the great void immortal treasure.

Full Moon of Nanshan shook his head constantly while watching from the side. The Green Fire Demon King was too autocratic and indulged in all sorts of evil doings. For someone like him, no one would oppose if Wu Yu was to kill and devour him. Furthermore, it would be gratifying.

The only issue now was that there wasn't a good opportunity for Wu Yu to make his move. After leaving from where the Purple Beaked Roc Demon King was, Green Fire Demon King headed to the next location to collection tributes. Subsequently, those who weren't willing to provide additional gifts were reprimanded before being coerced to giving up more treasures.

Through this, he would stand to gain more. Green Fire Demon King wouldn't care how tedious it was for these demon kings to collect the treasures. To him, he represented the Diabolical Dragon King and could do as he wish. He was just collecting one-quarter more gifts in addition to the tributes!

If they were really capable, they could complain to the Diabolical Dragon King! The Diabolical Dragon King wouldn't have time to entertain such trivalities......

Moving forward, Wu Yu's group tailed closely behind while constantly keep a lookout for an opportunity to deal with Green Fire Demon King.

All along, Green Fire Demon King was relatively shameless and always had other demon kings around him. If Wu Yu wanted to impersonate Green Fire Demon King to infiltrate into Underworld Dragon's Den, it would be best if he did not act recklessly. If others informed against him, Wu Yu's group would be finished!

Soon, Green Fire Demon King stopped leisurely on a mountain peak where a fox demon couple resided. Wu Yu's group also landed on the mountain peak.

Green Fire Demon King knocked restlessly on the doors. When the doors opened, the fox demon couple had their tributes brought to him at almost the same time. In total, the amount was close to two and a half portion. The additional was naturally gifts for the Green Fire Demon King.

The fox demon couple understood well the norms for the Green Fire Demon King and saw this as paying protection fees. After all, the cultivating conditions in Fiendish Underworld Metropolis were definitely better than the outside. Although it pained them to pay these tributes, this was still within their expectation.

To their surprise, when Green Fire Demon King saw the fox demon couple, his eyes rested on the female fox demon king.

The female fox demon was indeed alluring. Green Fire Demon King took a fancy to her at first glance and naturally wouldn't let them off!

"Hehe! With just these tributes, you think you could slip through it? Do you think i'm doing this for free?"

Green Fire Demon King hid away a portion of tribute abruptly. Immediately after, he only had some scattered immortal essences and precious treasures left on his hands. All these together would only make up one and a half portion of tributes!

Under usual circumstances, the other party would definitely by furious. Basically, few would top up the tributes to make up for the portion that was hidden away.

After all, the tributes were substantial to begin with. For those demon kings that had just entered the Great Void Demon Immortal Realm, it was a tough nut to swallow. Who would possibly pay an additional portion of tribute? Moreover, Green Fire Demon King was shameless to behave so!

The female fox demon was Zi Zhen Demon King while the male fox demon was Zi Quan Demon King. They were exasperated and knew Green Fire Demon King was making things difficult for them. At the same time, they realized they would probably be in trouble today.

Seeing the lust in how Green Fire Demon King was looking at Zi Zhen Demon King, they knew what Green Fire Demon King was trying to do immediately.

"Green Fire Demon King, we offered two and a half portions of tribute. We definitely offered sufficient. Would it be that your Honor have mislooked?" Zi Quan Demon King said calmly. For him, going against Green Fire Demon King was not an option. However, he couldn't afford to pay another portion of tribute.

After all, the couple rarely left their residence. The tributes they were paying were largely earned more than a hundred years ago. They had nothing left to offer.

"Tsk! Know where you stand! How dare you doubt my judgement! What gives you the courage!"

Green Fire Demon King's eyes turned unusually cold while still staring lustfully at Zi Zhen Demon King. In her human form, she was a stunning lady. After all, she was a fox demon. Her beauty had lethal attraction to both man and demon.

Therefore, he smiled sheepishly and said, "Let's do this. I wouldn't report the fact that you guys are paying sufficient tribute to the Diabolical Dragon King. I'll just top up the missing portion personally. The condition is... You are Zi Zhen Demon King, right? Follow me to my Green Fire Demon Palace and wait on me!"

Green Fire Demon King had an obvious lustful expression on him. In order to get his hands on the beautiful female fox demon, he resort to such unscrupulous means! How shameless could he get!

"No!"

Zi Zhen Demon King was exasperated. He had been with Zi Zhen Demon King for countless years and had always cultivated together. How could he allow his wife be taken away?

Moreover, if she was brought to the Green Fire Demon Palace, her wife wouldn't have a good outcome. It was apparent Green Fire Demon King was going to toy with her. If she was taken away, her fate would be ghastly.

At the thought of this, Zi Quan Demon King stood in front of Zi Zhen Demon King. Steeling his resolve, he attempted to stop Green Fire Demon King. "Your Honor, we have provided sufficient tributes. Please leave this place. We are at the critical stage of cultivation. We wouldn't be seeing you off. If you are determine to harrass us with unreasonable demands, I'll definitely report to the Diabolical Dragon King. After all, we have paid our tributes and Your Honor would definitely ensure the safety of us in the Fiendish Underworld Metropolis!"

Zi Quan Demon King was at the third tier of Great Void Demon Immortal Realm. As compared to Great Fire Demon King, the difference was stark and he definitely wasn't a match.

Therefore, he could only bring up Diabolical Dragon King at this point.

What he didn't know was Green Fire Demon King wouldn't be intimidated by the slightest. Green Fire Demon King had received threats that were much worse and yet he still lived well to this day!

As for those who threatened him, they had long been sent to hell!

Therefore, he wasn't intending to argue. Since the other party wasn't cooperating, he would just have to use force!

Green Fire Demon King transformed into his true form and his body was covered in flaming green armor scales. A flaming wild boar stood before the couple.

Seeing the true form of Green Fire Demon King, Zi Zhen Demon King had an urge to throw up. She had to be wasted by a wild boar? If that's the case, she would rather commit suicide on the spot!

Seeing Green Fire Demon King was about to make a move, Zi Quan Demon King and Zi Zhen Demon King wouldn't just sit back and await their deaths. Therefore, both of them transformed into their demon fox true form.

"Tsk. Still thinking of resisting? You are courting your own doom!"

Green flames burst forth from the body of Green Fire Demon King. The powers of green fire heavenly rule swept towards the fox demon couple, seemingly capable of torching anything in this world. Clearly, the fox demon couple wouldn't be able to withstand powers of this level.

At this very moment, Zi Quan Demon King pushed her girl out of range and withstood the green fire heavenly rule himself. Seeing Zi Quan Demon King was about to be blazed by the green fire heavenly rule, Zi Zhen Demon King was in despair. "Zi Quan! NO!"

Zi Zhen Demon King fell on a neighbouring mountain peak while Zi Quan Demon King took the green fire heavenly rule power himself. Instantly, he was on the brink of death. His demon fur through his body was charred and he could no longer stand up.

"Hehe! How dare you oppose me! You are courting your own death!"

Seeing this, Green Fire Demon King acted as though he had just killed a housefly. He didn't attach any importance to Zi Quan Demon King at all.

Immediately after, he looked lustfully at Zi Zhen Demon King and said, "Shouldn't you hurry back to the Green Fire Demon Palace with me so I can shower my love on you? I'll definitely make you so comfortable that you wouldn't want to leave. Hahahaha!"

Zi Quan Demon King was still worrying about her husband, Zi Quan Demon King. However, Green Fire Demon King was pressing towards her and even had her tied up with the power of a heavenly rule. Chains made of green fire had Zi Zhen Demon King bounded, forcing her to turn into her human form.

Green Fire Demon King changed into his human form swiftly. Looking at his actions, it would appear that he wanted to violate Zi Zhen Demon King right here.

Watching Zi Zhen Demon King gradually change to a beautiful lady with snow-white skin, Green Fire Demon King's eyes lit up. He wanted to pounce on her and pass his judgement on her instantly.

Wu Yu's group who had been watching from the side could no longer hold back.

While tailing Green Fire Demon King, the savage and brutal actions were unbearable. Now, he wven wanted to violate a female fox demon in public. This had breached the tolerance level of Wu Yu!

Initially, Wu Yu wanted to wait for a better opportunity to make his move. However, he could no longer hold back.

The soul of Great Sage, Heaven's Equal was raging furiously in his body and elevated his battle will. Watching how the events had unfolded before him, he couldn't just cast it aside. Even if he was to kill the Green Fire Demon King, the fox demon couple would likely not report against him. After all, the feud between the fox demon couple and Green Fire Demon King was now too deep!
