"Kunpeng Demon King" trembled in fear.

It seemed like he was weak with fear after realizing that he had delayed the Diabolical Dragon King's plans.

At the same time, Wu Yu looked past Diabolical Dragon King, and saw Jiu Ying standing rigidly behind him. His eyes were lifeless, and he was completely silent, standing obediently behind Diabolical Dragon King.

Wu Yu's heart pounded upon seeing this. However, he knew that he could not rush this, or he might make a huge blunder.

As he still did not know what was up with Jiu Ying, it was best to let the situation play out a little more.

Diabolical Dragon King gave a disapproving cough, and his murderous intent assailed them. However, perhaps because the matter he had called them back for was more important, he did not attack, but simply said coldly: "Do you know where Green Fire Demon King is?"

This question from Diabolical Dragon King clearly revealed his suspicions. Ordinarily, one would take at most three months to return after receiving an immortal message talisman summons from Diabolical Dragon King.

This time, Kunpeng Demon King had been very late already. Green Fire Demon King could not be later than he was. If he had not yet returned, then it was likely that he had met with an accident.

Ordinarily, the Fiendish Underworld qi in the Fiendish Underworld Metropolis was conducive for the demon kings' cultivation. Therefore, they seldom wandered far from Fiendish Underworld Metropolis/ This time, Kunpeng Demon King had also returned later than usual.

"Green Fire Demon King? Why, I have no idea where he is."

As Kunpeng Demon King, Wu Yu lied. This was something that he was rather worried about. However, it seemed like no one knew that Green Fire Demon King had left together with him.

Therefore, he just had to firmly deny any knowledge. If there was no lead to go on with, then the matter would go cold.

But to Wu Yu's surprise, a 6-heavens demon king stood up.

It was a huge worm demon, whose body was completely black. It had many feelers extending out from its body, and also looked to be covered in some poisonous substance. Most striking of all were the 10,000 eyes on its head. They looked like ghostly immortal eyes from hell, and had an eerie look to them.

This was the 10,000 Eyed Larvae, also known as the Larvae Demon King, and he was a 6-heavens demon king. He was not on particularly good terms with Kunpeng Demon King, and had even clashed with him over matters in the past.

At this time, Larvae Demon King stood out and sneered: "Kunpeng, what nonsense are you on about? A few months ago, I clearly saw you leave Underworld Dragon's Den together with Green Fire Demon King. If no one knows where he is, then it has to fall to you. A pity I didn't follow you then to see what you two were doing. Otherwise, I might know the fate of Green Fire Demon King."

Diabolical Dragon King narrowed his eyes at these words. A threatening wave of chilly power came washing over Kunpeng Demon King.

Wu Yu could feel Diabolical Dragon King's anger!

Without question, lying was a huge sin. If he had been open about it, forgiveness might have been granted.

Either exposing Wu Yu's true identity or incurring the wrath of Kunpeng Demon King was not at all favorable for his plan of action. Therefore, he had to protect Kunpeng Demon King's life.

Kunpeng Demon King was a hard-won identity, and he could not abandon it so easily.

"May the great king forgive me!"

Wu Yu hurriedly answered. "Green Fire Demon King was killed by me. I had good reason to."

Hearing him confess to the murder of Green Fire Demon King shocked many of the demon kings, to whom his actions were unthinkable.

Internal killing within Underworld Dragon's Den was forbidden. If found out, one would be cast out from Underworld Dragon's Den.

Of course, now that Wu Yu saw Diabolical Dragon King had an urgent matter on hand, he decided to reveal this, judging that he would not be killed for the moment. Otherwise, he would have been shown no mercy.

Hearing Wu Yu's words, Diabolical Dragon King demanded: "What reason could there be? He offended you?"

No matter what, Green Fire Demon King was a member of Underworld Dragon's Den. Although he was of no individual importance to Diabolical Dragon King, but it was a question of face, and the abidance by Underworld Dragon's Den's rules.

All along, no demon king had dared to commit murder amongst their brethren at Underworld Dragon's Den. But once a precedent had been set, problems were likely to occur.

Therefore, Diabolical Dragon King was now considering how to deal with Kunpeng Demon King.

More importantly, he wanted to hear what Crimson Moon Kunpeng's reason for killing Green Fire Demon King was.

Wu Yu thought quickly and said: "Because I humiliated Green Fire Demon King many times before, he was resentful towards me. He found a forbidden ground and deceived me with a lure of eternal demon emperor blood. He trapped me there. It was a hateful gesture, and he went overboard with it. Luckily, I found him out beforehand, or I would not have returned. In my rage, I killed him......"

This was the story that Wu Yu had come up with.

After obtaining Crimson Moon Kunpeng's memories, he knew that he had been an impulsive character. Therefore, an emotional killing was well in character for Crimson Moon Kunpeng, and would not call undue suspicion to him.

The demon kings were silent after hearing his plea. They were all watching to see how Diabolical Dragon King would deal with Kunpeng Demon King.

It was Golden Bee Demon King, who had been on good terms with Green Fire Demon King, that was surprised. He had not seen Green Fire Demon King for a while, and then he had shown up briefly only to disappear again. He was a little confused.

This Green Fire Demon King really thought he was something special, to dare to plot against Kunpeng Demon King. That was tantamount to suicide!

Golden Bee Demon King showed some crocodile tears, but did not mind overmuch. Green Fire Demon King had been asking for it.

After hearing this "reason", Diabolical Dragon King remained emotionless. Without saying anything, he moved. A terrifying aura flashed over the heads of the other nine demon kings.

An arc of black light with a diabolical dragon coalesced, and swam through the air towards Wu Yu!

This arc of black light held incredible power, and the demon kings present trembled in its presence. This was only a ninth of Diabolical Dragon King's power, and not his full strength. Even the three 7-heavens demon kings could feel its strength. Not even they would have been able to block that blow.

However, Diabolical Dragon King had not put any killing intent into this blow. Evidently he did not wish to kill Kunpeng Demon King, but simply punish him.

The black light landed on Kunpeng Demon King, and his entire body was covered in wounds. The surface was a bloody pulp, and his towering reddish frame was now covered in a sickly red color.

This was the color of fresh blood. However, it did not kill Kunpeng Demon King off. Diabolical Dragon King had not intended to kill him.

"Crimson Moon Kunpeng, killing Green Fire Demon King from Underworld Dragon's Den is a sin that cannot be overlooked. I confine you to Underworld Dragon's Den, and not to set half a foot out for 10,000 years, on pain of death."

Diabolical Dragon King's harsh tone was a bizarre contrast to how lenient the sentence actually was.

Wu Yu too did not know if Diabolical Dragon King believed his excuses. In any case, it seemed like he still had a use for Kunpeng Demon King. Otherwise, he would probably have cut him down on the spot as an example and deterrent to the other demon kings.

Wu Yu was dripping with blood. However, he did not say anything, but continued to tremble in fear.

Actually, this little bit of pain meant nothing to him. It was just like when he was cultivating the Eternal and Indomitable Vajra Realm. Compared to the knives carving him up, this was like scratching an itch.

Of course, in the Diabolical Dragon King's eyes, this was quite a severe blow that he had dealt to Kunpeng Demon King.

This was one advantage that Wu Yu had over others. If they were at the same cultivation realm, they were far inferior to him, while he could challenge opponents above his own cultivation realm. This power had not simply dropped into his lap. Instead, it had been cultivated through the hardship that he had faced all this while.

Cultivating the Eternal and Indomitable Vajra Realm had been thousands of times harder than this. Naturally, this was nothing to him.

However, Wu Yu still feigned agony as he continued to cringe. He knew from Kunpeng Demon King's memories that he seldom endured such pain, and so could extrapolate an appropriate reaction.

Therefore, this identity would not be exposed, and Diabolical Dragon King and the others would not suspect anything.

10,000 years in Underworld Dragon's Den was a relatively light sentence. It seemed like Diabolical Dragon King had a big mission for them. Therefore, he had only dished out a minor punishment that meant nothing much to Wu Yu.

If he wanted to leave Underworld Dragon's Den, he could do so anytime. And after he left, Diabolical Dragon King would be able to find no trace of Kunpeng Demon King.

Of course, Wu Yu would not casually give up the identity of Kunpeng Demon King.

It was an important disguise. He continued to look intently at the puppet-like Jiu Ying standing behind Diabolical Dragon King. He vowed to himself that he would get to the bottom of the matter. If he was in trouble, Wu Yu would definitely save him!

Currently, if Wu Yu was forced to, it was not impossible to take Diabolical Dragon King on. It all depended on what would happen next. If Diabolical Dragon King was going to rely on them, he would definitely find a chance to further his own plans within them!
