The Poison Dragon said to Klein, "Very good. You've kept your word. Now, let's begin the next transaction."

As for the landing spot that Klein had mentioned...

Although the Poison Dragon was surprised, it knew that it was impossible to resolve it in a short period of time. It could only comb through its magic afterward.

However, if the Poison Dragon, who was proud of, only had such a powerful AOE spell, then the other party would definitely suffer greatly.

Upon hearing the Poison Dragon's words, Klein nodded.

"In that case, tell me about Raksha. What is its identity?"

"Rakshasa? It's just a small fry. It's the king of this low-level catacombs world. However, this person is very scheming. It seems to have sacrificed many things and obtained the approval of a mysterious existence," the Poison Dragon said slowly.

Upon hearing the Poison Dragon's words, Klein frowned slightly.

There were many things that were revealed.

Firstly, Raksha wasn't very powerful. At the very least, before the Poison Dragon was imprisoned, its strength shouldn't be much stronger than the Poison Dragon's.

At the moment, it was at most at tier 10.

With this in mind, Klein inexplicably heaved a sigh of relief.

He thought that all of this was the layout of Raksha.

If that was the case, he might have to re-evaluate the strength of Raksha.

As for the low-level catacombs world that he mentioned...

This was just as Klein had guessed.

Why?

Because this catacombs world was too barren. There were no signs of any civilization.

This was very wrong.

After all, there was a lot of evidence that showed that the catacombs world had existed for a very long time.

How could a catacombs world that had existed for such a long time not have a civilization?

They didn't see it. There was only one possibility, and that was that the civilization wasn't here.

And a level 2 cave was very good proof.

"Alright, human, quickly come and cut off my restraints."

The Poison Dragon interrupted Klein's thoughts.

Klein looked over when his thoughts were interrupted.

Then, he nodded and flew over with the Endless Sword.

Coming in front of the Poison Dragon, Klein brandished his blade, ready to slash.

But at that moment, the Poison Dragon's eyes revealed a hint of strangeness.

This hint of strangeness made Klein immediately realize that something was wrong with the Poison Dragon.

There must be a backup plan!

Therefore, Klein slowed down.

And at that moment, the Poison Dragon saw Klein's Endless Sword getting closer and closer to the chain, and it couldn't help but feel its heart clench.

But at the same time, its mouth was tightly shut.

Its four gigantic arms were also on guard.

Upon seeing this, Klein guessed the Poison Dragon's intentions.

But it hadn't acted in advance.

Therefore, he continued slashing, and just as Klein was 0.01 centimeters away from the chain...

In the Poison Dragon's eyes, Klein had already slashed down, so it couldn't help but open its mouth.

But at that moment, the magic energy that was nurtured in the Poison Dragon's mouth instantly spread out.

Sensing the magic, Klein didn't say a word as he flew away.

And at that moment, the Poison Dragon looked at the iron chain that was about to be cut off. In the end, he still didn't cut it off, and its state of mind instantly exploded.

It knew that Klein had noticed it.

But it was impossible for it to admit that it had some ulterior motives.

Therefore, it questioned angrily, "Human, why didn't you fulfill what you promised me?"

Klein stood not far away from the Poison Dragon with a blade in his hand and looked at it mockingly.

He thought to himself, 'Darn beast, to actually play such a trick on me! However, this is exactly what I wanted!'

Then, he said, "I suddenly thought of something. If I let you out just like that, it would be difficult to guarantee my safety."

"Oh? Then you regret it?"

The Poison Dragon's anger was accumulating, like a volcano that was about to erupt.

"No, no, no! Of course not. Humans are very trustworthy, especially me. I can't wait to let you out immediately, but you're powerful now, so I have to be very careful," Klein said.

"Then what do you want?" the Poison Dragon asked with an unfriendly expression.

Upon hearing the Poison Dragon's words, Klein pretended to think for a moment.

"How about this? Let's form a contract. Only then will I be at ease with you."

"Contract?"

Upon hearing this, the Poison Dragon instantly flew into a rage.

"You actually want to form a contract with a proud dragon? That's impossible, absolutely impossible!"

"Unless you're a servant and I'm the master."

Klein looked at the Poison Dragon as though he was looking at a fool.

As expected!

In novels, dragons were said to be arrogant and foolish creatures.

Now, it seemed like the description was completely correct.

The Poison Dragon had no idea what position he was in, yet he still dared to speak such shameless words!

"So there's nothing to talk about?" Klein said with a frown.

"Are you going to let me go or not?" the Poison Dragon asked again. "Human, you promised me."

Klein said with a cold snort, "If I'm not mistaken, if I had slashed down just now, your magic attack would have been instantly activated, right?"

"At that time, you would be able to gain your freedom and also kill me. What a good plan!"

"Bullsh*t! Despicable human, I knew you didn't have good intentions!"

The Poison Dragon was completely enraged.

The magic on its body began to evaporate.

From afar, there seemed to be countless waves of air churning within.

Not only that, the chains on its body also emitted cracking sounds as countless magic evaporated.

As for Klein, he couldn't help but furrow his brows when he sensed the massive magic that suddenly appeared on the Poison Dragon's body.

'As expected, this Poison Dragon isn't simple. Thankfully, I didn't release it. Otherwise, it's very likely that I won't be a match for it in its entirety.'

Sensing the distance between the spells, Klein had no choice but to retreat again and again.

There was no other way!

The spells it was releasing were several times stronger than before.

Clearly, this Poison Dragon was hiding its strength.

Its goal?

Naturally, it was him.

However, its plan had been broken, so it was naturally enraged from embarrassment.

Soon, the Poison Dragon's magic was completely stored up.

At this moment, a huge ball of light appeared in its mouth.

This ball of light had an extremely dense magic power on it.

After coming out, the surrounding elements of heaven and earth became more active.

They continuously revolved around the ball of light.

As the speed of the rotation became faster and faster, the elements of the entire heaven and earth were stirred up.

Before long, countless elemental powers formed a huge tornado in front of it.

The tornado stabbed straight into the poison lake.

The poison lake flew into the wind without any resistance.

However, what Klein didn't expect was that the moment the poison lake flew up, the Poison Dragon opened its mouth and sucked violently. Instantly, the poison lake flew into the Poison Dragon's mouth.

From afar, this scene looked like a dragon sucking water from the surface of the sea in his past life.

However, the scene before his eyes was even more shocking.

At first, the poison lake was only a few dozen meters away, but soon, it was 20 meters, 30 meters, 50 meters, and 100 meters!

Soon, the entire poison lake was shaken and crazily rushed toward the Poison Dragon.
