The next day.

Klein woke up very early to make preparations.

After resting for so long, Klein's injuries and the magic in his body had reached the most perfect state.

Not only that, after the series of battles, Klein felt that the magic in his body had increased by quite a bit.

Indeed.

After all, he had experienced a series of life-and-death battles.

The magic in his body had been depleted several times, and every time, he was in a life-and-death struggle. Under such circumstances, it was normal for Klein's magic to increase.

'It's time to enter the next dungeon! However, where is the entrance?'

Klein stood in front of the base and looked around.

Beside him were Little Wind and Little Fox.

Although the two beasts were weak, they were very practical.

For example, searching for something!

Following that, Klein asked each of the two beasts to choose a direction to search.

And he directly chose the front and came to the mountain range where the great battle had taken place.

The originally majestic mountain range was directly shattered into pieces by the repeated battles.

Later on, Klein experimented with his skills again and again, and in the end, the ground turned into a complete mess.

Klein came here and looked around.

Suddenly, the mountains and rivers shook, and the ground churned. It was as though something was turning over.

Before long, a stone platform rose up.

Following it was a green teleportation door.

This was different from the door Klein had experienced in the previous world.

The color of the green was even more obvious. At a glance, it was as though the door had just been pulled out of a lake filled with poisonous gas.

At this moment, sticky venom was constantly dripping down from countless spells.

The dripping venom corroded the earth into many different-sized holes.

It let out a series of sizzling sounds.

"Is this the passageway to the next world?"

Klein frowned.

This teleportation door was different from the previous one.

The previous teleportation door wouldn't be like this, nor would it reveal waves of brutality.

Why?

Because the teleportation portal didn't teleport a person to the front of a crypt creature.

Instead, it transported a person to the black membrane outside the cave.

Only by breaking the black membrane could a person enter, and everything inside could be sensed by others.

But it was different from this!

Even when standing in front of the teleportation portal, Klein could still clearly sense the deterrent force inside.

"It looks like the next boss isn't easy to deal with! But that's true. It might be the Poison Dragon. It looks like I have to be careful," Klein muttered.

The two beasts also sensed a powerful magic fluctuation from the enemy where Klein was.

Therefore, Klein didn't summon them, and they rushed back on their own.

Seeing the scene in front of them, the two beasts revealed some doubts.

Compared to humans, beasts had sharper senses.

They could deeply sense that there was a powerful existence inside.

This powerful existence was like a natural enemy to them.

When they met, their combat strength was halved.

The two beasts looked at each other knowingly.

They could see the other party's fear.

Therefore, Little Wind and Little Fox tugged at Klein's clothes, hoping that he wouldn't enter.

But how could Klein agree to it?

Besides...

Even if he didn't kill the Poison Dragon, he wouldn't be able to leave the dungeon.

Furthermore, Klein still had to find the Poison Dragon Ghost Gold.

Therefore, no matter what it was, Klein had to go in.

Klein pacified the two beasts before putting them back into the base.

Of course, Klein didn't dare to be careless.

Then, he took out the Endless Sword.

He clenched it tightly and felt the terrifying power coming from the Endless Sword, making Klein feel much more at ease.

In addition to the two powerful magic skills he had just learned, it made Klein feel much less worried.

With this in mind, Klein no longer hesitated and strode into the teleportation portal.

A moment of stellar transposition.

Klein arrived at his destination.

His feet lightly stepped on solid ground.

This made Klein's heart, which had been a little worried, feel a lot more at ease.

He didn't know what kind of teleportation portal it was.

In any case, every time Klein went through a teleportation, he would feel a massive sense of weightlessness.

This massive sense of weightlessness made him feel extremely insecure, as though he had entrusted his life to someone else.

"If I have the chance in the future, I'll learn how to use a teleportation door myself!"

"Although the feeling of weightlessness is very strong, it's indeed useful!"

Klein muttered to himself.

Then, he looked at the black membrane in front of him.

The black membrane didn't shatter as Klein had expected.

Instead, it was in perfect condition.

However, the black membrane was different from what Klein had seen previously.

The black membrane was green in color.

He could vaguely see sticky things slowly flowing down from it.

And that wasn't all.

The black membrane, which had a powerful insulating ability, was now like a sieve.

The pungent smell from the outside spread into the black membrane like smoke.

Klein accidentally took a whiff and instantly felt as though he had stuffed a red-hot piece of charcoal into his nose.

Clearly, this world was different from the previous one.

"Hmph, what a charlatan!"

Klein picked up the Endless Sword and kicked open the black membrane.

When the black membrane was kicked open, the world inside was revealed.

However, what Klein didn't expect was that it was a world of water!

That's right, other than the three-meter-long and wide land beneath his feet, the rest was water.

Not only that, above the water, there was an endless amount of fog.

From afar, nearly half of the world was filled with this fog.

It made the world look somewhat beautiful.

'How strange.'

Looking at everything in front of him, Klein wasn't careless at all.

Having lived underground for a long time, he knew that the more beautiful and mystical a place was, the more bizarre it was. It was filled with killing intent.

This was especially so for the world in front of him.

Although he hadn't been here for long, he already had goosebumps.

And that wasn't all.

It was as though a malicious intent had locked onto him in this world.

This malicious intent wasn't small. It was as though it had enveloped Klein's entire body.

This feeling wasn't good.

It was as though a layer of shackles had been placed on him.

His speed and strength had been greatly suppressed.

"Is this the wonder of this world?" Klein said with a frown. "It seems like I have to be more careful. Furthermore, it seems like the air in this world is also poisonous!"

But where did this poison come from?

Klein looked around, but he couldn't see the source.

Although it wasn't enough to injure Klein, the omnipresent poison gas continued to reduce Klein's HP.

And not only that, Klein felt that the poison gas was strengthening bit by bit.

It wasn't much, but he knew that once it was stacked to a certain extent, even if Klein didn't make a move, he would still die silently at the hands of the enemy!

'Looks like this last Poison Dragon isn't easy to deal with!'
