Chapter 552 - Stealth Operation

At this moment, Klein had used the most crucial item he had on him, the invisibility cloak.

That's right, it was the cloak that the bald uncle had given him.

Previously, he had used it for magic conversion. It was often used as a flying carpet, flying around in the air.

Instead, he had neglected the use of the invisibility cloak. This time, it was of great use.

The two of them were wrapped in the invisibility cloak. Although it was a little tight, it could basically make them invisible.

James blinked. "Is there really no one outside who can see us?"

"Don't worry! The bald uncle's invisibility cloak can be considered the one with the highest magic power in the world. Even if Demon King Saxe were to personally come to the scene, he might not be able to find the two of us!"

Klein had previously found it strange that such a mystical item was in the hands of an uncle who didn't have any powers.

He didn't have the time to ask the uncle about the origins of the cloak.

However, if such a treasure were to fall into the hands of someone with weak powers, it would only invite disaster.

Therefore, Klein accepted the gift with ease.

With the protection of the invisibility cloak, the two of them easily arrived at Demon King Saxe's territory.

Only then did they realize that his territory was even more sinister and terrifying than they had imagined.

Demon King Saxe lived in a huge cave.

Everyone who entered wore pitch-black cloaks and used black cloth to cover their faces.

It was said that these people were the legendary black mages!

Black mages were the darkest and most despised type of magic in the world.

In this world, black light mages were like rats that everyone wanted to beat up. Anyone who saw them would scoff at them,

Compared to other light magic, black mages were indeed more aggrieved,

Therefore, those who practiced black magic went underground and did things that were shameful.

He didn't expect that Demon King Saxe would gather so many black mages. It seemed like he had an ulterior motive!

James lowered his voice and said, "I heard that Demon King Saxe is indeed refining something very impressive. He has plundered all the mineral resources in the vicinity and is even doing his best to excavate and collect a type of gemstone. What exactly do you think he wants to practice with this thing? What does it have to do with these black mages?"

Klein shook his head gently. He wasn't very familiar with Demon King Saxe's strange plot.

If he could expose this plot while he was here, he would be killing two birds with one stone.

As they entered Demon King Saxe's cave, the strange atmosphere became more and more intense,

There seemed to be no one speaking. Everyone lowered their heads and did their own things,

They felt an incomparable sense of oppression enveloping their entire bodies.

Fortunately, no one noticed that Klein and James were hidden in the cape, taking everything in their sights.

Among them was a black-robed man wearing a bear mask. He was holding a whip in his hand as he chased away the slaves who were working for them.

These slaves were probably young, strong laborers that they had kidnapped from other dimensions.

Klein suddenly recalled what the bald uncle had told him previously.

It was said that the daughter of the uncle who had secretly stolen her was also captured by Demon King Saxe. Her whereabouts were still unknown, and her fate was unknown,

If she could be rescued together this time, it would be considered a great deed!

And these young laborers seemed to be transporting some materials into Demon King Saxe's cave,

Some of them were carrying them on their shoulders, while others were hugging them with their hands. Everyone was out of breath and looked like they were about to run out of energy. It was unknown how long they had been working...

Klein frowned slightly. Demon King Saxe was indeed a devil that exploited humans!

This gave Klein the determination to eradicate him.

Under the cloak, the two of them gradually arrived at the core of the cave.

It looked like an extremely spacious cave, but there was not much space for people to move about.

Because the bottom of the cave was burning with a raging fire. If one fell into the fire accidentally, they would be doomed!

At this time, even James was a little cautious.

And above the raging fire, a huge stove was suspended in the air.

As the high temperature of the sea of fire roasted the substances in the furnace, it seemed to have completely dissolved.

The cannons that popped out looked extremely strange and terrifying.

It was as though an ancient witch was refining something that made one's hair stand on end.

At this moment, Klein and James both understood that what was being refined in the huge furnace was probably the item that Demon King Saxe had to obtain.

Following that, many young and strong laborers climbed up the ladder beside them and poured the materials into the furnace,

With a few sizzling sounds, the reaction inside grew louder and louder.

Some of the strong laborers were already exhausted after working for a long time.

The moment they stepped into the sea of fire, their feet felt weak, and then they fell down.

Following that, a blood-curdling scream was drowned out by the disaster. The scream made one's hair stand on end.

"'Holy s*t, this is too terrifying. What Saxe did is completely unethical!"

As the sea of fire and the furnace emitted crackling sounds, Klein and James's whispered conversation was successfully covered up.

Klein also sighed softly. If this continued, Demon King Saxe would really use his own abilities to overturn the world. He had to be stopped immediately!

Furthermore, according to the legends from the outside world, once the thing Saxe refined was successful, it could bring about an apocalyptic disaster!

Of course, what caught the attention of the two of them the most wasn't the burning sea of fire and the stove, or the strange substances inside.

Instead, it was a group of figures tied tightly by pitch-black ropes in the middle of the cave.

These people were the crow legion in black cloaks. and lying in the middle was the target that Klein and James wanted to rescue this time, Gray!

Gray seemed to be seriously injured. His body was covered in blood, and his face was covered in a bloody mist.

At this moment, he had already fallen into a coma and wasn't moving at all.

Klein was anxious. He didn't know how Gray was doing.

He hoped that he could hold on no matter what...

At this moment, Demon King Saxe was sitting on a high throne, and a few of his subordinates were bandaging his wounds.

That slash was indeed very powerful. If not for Demon King Saxe's unique physique, he would have already bled to death.

At this moment, Demon King Saxe's face was pale, and even his breathing sounded urgent and angry.

It seemed that he was very angry about this serious injury.

He used his intact hand to point at the few subordinates who had betrayed him under the throne, and began to express the infinite anger in his heart.

"You guys are really too hateful. How dare you betray me? I won't let you off today!"
