When people faced the unknown, they would have an incomparable fear.

And now, the royal envoy had fallen into this nameless fear.

What... What was that thing!

The royal envoy was extremely afraid. He frantically increased the intensity of his investigation, trying to figure out what was causing this.

However, no matter how hard the royal envoy tried to investigate, he could not find out anything about that place.

"You're courting death!"

The soldier of the Nether King Guards, Lawrence, raised his supreme sword high up in the air and slashed down fiercely.

Boom! Boom! Boom!

The sky and earth changed color!

The entire Underworld was focused on this sword strike. Many royal members were so frightened that they lost their temper. They sat on their thrones and panted heavily. They looked around in fear, afraid that the target of this sword strike was them!

And this was just the residual power of this sword attack!

Even the residual power was so terrifying!

Skeleton King City.

The Skeleton King had completely lost his temper. Under his feet, all the courtiers hid under the table in fear, crying and shouting.

Today... What happened today...

The Skeleton King forcefully endured the fear. He stood up and walked to the window with trembling steps. He carefully opened the curtains.

Looking at the terrifying energy fluctuations outside, the Skeleton King felt a wave of fear. The magnitude 10 earthquake just now did not scare him. He could sit firmly on his throne but, this time, he could not sit still.

Just now, when the two powerful energies converged, it only made the Skeleton King nervous. But now, there was only deep fear in the Skeleton King's heart.

The final explosion was just a sound, but it contained more than just terrifying energy!

It contained a kind of majesty, the kind of majesty of a king.

It was as if there was no existence in the world that the other party looked up to. That terrifying majesty had already caused the Skeleton King's perception to go wrong.

In this world... who else could have such powerful energy...

Could it be... could it be that the southern undead king had successfully broken through?

No, that fellow definitely couldn't have broken through to the peak of the god realm in such a short period of time. Thinking back to how he had reached the peak of the god realm in a hundred years, stepping into most of the mountains and rivers of the Underworld. Stepping into every single land with all sorts of illusions and secret realms...! He had used all sorts of natural treasures to his heart's content. However, no matter what, in the course of a hundred years, he hadn't been able to break through to this realm!

In the end, he had simply gone into closed-door training. After going into closed-door training for a few hundred years, he had barely managed to break through to the peak of the middle god level by chance and reach the highgod level. It had only been a few decades... How could that fellow have broken through to the peak of the middle god level at such a fast speed...?

Impossible, absolutely impossible!

But if that was the case..

Who could possess such heaven-defying majesty?

Could it be...

That the Nether king...

The instant these two words appeared, his heart suddenly began to thump.

That was a forbidden name!

The kings were absolutely terrified.

Just reading that person's name would cause them to have nightmares.

The Master of the Underworld, the King of Ten Thousand Kings.

The Nether King.

The Nether King was already a thousand-year-old legendary existence.

Many underworld creatures thought that the Nether King was just a fictional character but they, the kings, knew that it wasn't a legend.

People who were a thousand years old all knew...

The existence of the Nether King... What kind of existence was he...

A thousand years ago, he gathered all the abilities in the world, and all the kings worked together to coax the Nether King into taking a nap.

In that era... he was still a nobody, and the young him was lucky enough to participate in the fear of everyone in that era...

That was the fear of the old kings...

Those new rising stars in the Underworld didn't even know about the legend.

The Nether King had slept for too long, so much so that they almost forgot the fear of being dominated in that era!

Such a terrifying ability, could it be...

That the Nether King had really awakened?

No, no, no...

The Skeleton King immediately rejected his idea.

Damn it, even though he was still very young at that time and his strength was far from what it was now, the fear from so long ago hadn't seemed to have been washed away by the river of time.

However, the Skeleton King vaguely remembered that the fear of the Nether King seemed to be even stronger than this.

It was a fear that he couldn't help but want to kneel down and worship.

Just as the Skeleton King heaved a sigh of relief, an emissary dressed in gorgeous clothes knocked on the castle's door.

However, after a long time, no one went forward to open the door.

"You bunch of cowards!"

The Skeleton King cursed angrily. It turned out that everyone was hiding under the table and trembling. They didn't dare to open the door at all.

"Come in!"

The Skeleton King waved his hand and the gate of the castle opened. The messenger bowed and walked in.

"My respected Skeleton King!"

The messenger walked into the hall and shouted loudly. Then he went to the throne of the Skeleton King and knelt down, kissing the hand of the Skeleton King.

"I am the messenger of the Underworld's Polar King. I am here to announce something!"

As he spoke, the emissary opened his bag.

"Cough cough!"

The emissary took out a gorgeous letter from his bag. He used a secret technique to open the encrypted envelope protected by the array. He took out the letter and handed it to the King of the Skeletons.

The Skeleton King received the letter curiously and opened it to read it quickly with his eyes.

However, the more he read, the bigger the Skeleton King's eyes became. His expression became more and more surprised.

This...

"Is everything in this letter true?"

The Skeleton King stood up with a solemn expression.

"My respected Skeleton King, everything in this letter is true. I swear on my life that if there is a switch during the delivery of the letter, I am willing to accept cruel punishment and hang my head high above your city gate, making me beg for death."

The messenger kneeled on the ground and said respectfully.

"Hmph!"

The Skeleton King suddenly flew into a rage and raised his hand to smash the armrest of the throne!

The throne made of special metal had extremely high hardness. With this smash, the Skeleton King actually smashed off a corner of the armrest.

All the ministers were frightened and huddled together. Every one of them dared to raise their heads to observe the Skeleton King.

"If what this letter says is true... sigh..."

After the Skeleton King was enraged, he was exhausted again. He sat on the throne and the letter slowly fell from his hand onto the ground.

"Dear Skeleton King, the Nether King has woken up and the guards are here. The situation is critical!"

The letter was very short. But such a short letter contained words that made the Skeleton King feel powerless...

It was all true.
