The fish had already taken the bait

Rachel and her companion discussed for a moment before a mermaid dived into the lava.

A minute later.

The mermaid returned with a pearl in her hand.

Furthermore, wherever she went, the lava would automatically separate as though it was wrapped in a transparent bubble.

Klein's eyes lit up.

Perhaps it was an item like a water repellent bead.

"What do you think of it?" Rachel asked carefully as she picked up the red bead.

"What do you think of it? It grows under the lava. It should be a good thing."

"Sure."

Klein nodded expressionlessly.

During the transaction, he couldn't let the other party see through his thoughts.

"Come, I'll teach you."

Klein lit a bonfire on the shore, took out his tools, and began to teach him how to roast meat.

The Magma Mermaid listened attentively to the lesson and quickly grasped the technique that wasn't complicated.

Finally, Klein completed the transaction with more than thirty pieces of meat and some seasonings.

[System notification: Rare Bubble Bead+1]

Klein took the bead.

He checked the details.

[Rare Bubble Bead: In a liquid environment, it will form a transparent bubble and provide sufficient oxygen. It can control the bubble's rise and fall according to its will.]

"How is it?" Rachel asked nervously.

"Barely."

Klein pretended to sigh.

"Sigh, since it's my first transaction with you, it's fine even if I suffer a small loss."

Rachel sighed and said, "Mr. Klein, you're such a good person. Thank you."

They had been staying here and didn't know anything about the outside world.

All they knew was that barbecued meat was rare to them, and bubble beads were of no use to them.

Both sides took what they needed.

Klein didn't leave immediately. Instead, he stayed behind to continue his conversation with the mermaids.

During that time, he suggested that they could trade again.

However, the mermaids didn't have anything good left.

At the bottom of the magma lake, other than bubble beads, everything else had turned to ash.

Although they couldn't trade, he could get some information from them.

Unfortunately, they had been here for a long time and knew very little about the outside world.

Klein also took the opportunity to test the effects of the bubble beads.

At first, he was worried that the bubble beads would lose their effectiveness, so he only dared to test them bit by bit.

After testing them many times, the bubble beads were indeed effective. He stayed in the transparent bubble beads and it didn't let any of the magma enter.

Furthermore, he wouldn't feel the heat inside. There was a constant supply of oxygen from afar.

Klein didn't dare to go too deep.

He was still worried about the bubble beads. If they suddenly lost their effectiveness, he would be burned to death.

Half an hour later, by the shore.

Klein spread out a small map and planned the next route.

He then said, "Continue digging to the right and then excavate the cave ahead."

"There's a water treasure chest here. It's marked as extremely dangerous."

"I'll go to the right to take a look first. If there's really danger, I'll change my route."

Klein put away the map and took out the Perfect Washing Machine Blueprint that he had obtained previously. He studied it first.

"Mr. Klein, do you want to have a child with me?"

At that moment.

A soft call came from within the lava.

Klein looked in the direction of the voice.

It wasn't Rachel, but another mermaid.

"We should be in reproductive isolation."

Klein wasn't too sure.

Looking at the innocent look of the little mermaid...

"I'm afraid she's only curious about having a child."

The mermaid tilted her head and asked curiously, "What's reproductive isolation?"

"Nothing."

Klein patted his head and said, "There don't seem to be any males in your group? This... how do you reproduce?"

"Drink magma," the mermaid said seriously.

"..."

Klein sighed.

"Magma is really omnipotent for you."

"Yes, yes."

The mermaid continued to ask in a daze, "You really don't want to?"

"There's no need. I'm leaving this place."

Klein shook his head repeatedly.

"Oh, you're leaving?"

The mermaid raised her voice.

The mermaids who were studying how to grill meat came over.

They tried to persuade Klein to stay.

"Everyone, I'm sorry. My journey is still very long. Perhaps we can meet again in the future," Klein said casually.

It wasn't like he could return the way he came.

It would probably be extremely difficult for him to return to the catacomb.

"I'm going now."

"The world is very big. We'll meet again if we're fated."

"Everyone, drink more lava in the future and live a good life."

With his back facing the mermaids, Klein waved his hand elegantly.

Little Fox and Little Wind followed behind him. They turned their heads every three steps, unwilling to part with the group of young ladies.

Klein came to the right side of the mud wall.

The map indicated that there was nothing in the catacomb on the right.

According to tradition, he still had to check.

Who knew if there were any crypt creatures passing by?

[Continue digging to the right. A Vine Monster just passed by. It enslaved two Flower Spirits. If you save them you can get two more free laborers.]

"There really are!"

Klein opened the illustrated book.

He checked the information on the Vine Monster and the Flower Spirit.

...

[Vine Monster: Walks in a desolate wetland, in a cold swamp. Its entire body is covered in dried branches and rotten leaves. It exudes a nauseating smell of decay. Everywhere it goes, other than the Flower Spirit who can help it clean up the trash, other creatures will be rolled onto its body. It will use the vines to firmly wrap around it. The liquid it secretes will slowly dissolve the gift into meat paste and be sucked dry of nutrients by it.]

[Ability: Fire-Extinguishing Odor]

[Weakness: Slow movement]

[Danger Factor: 58]

...

Check ability.

[Fire-Extinguishing Odor: Releases odor, can extinguish most of the flames.]

[Flower Spirit: Miniature elf, smaller than the size of a palm, possesses extraordinary strength. Is born kind, never does evil, likes to be a hardworking little gardener, often bullied.]

[Ability: Growth Halo]

[Weakness: Weak resistance]

[Danger Factor: 1]

...

Check ability.

[Growth Halo: The plants around it are healthier and grow faster.]

...

After reading the Flower Spirit's information, Klein became even more determined to save them.

How could such a kind little creature work for such an ugly monster?
