After the Gold-Digging Dwarf looked at the reputation trading card in Klein's hand, he suddenly had no intention of escaping.

The two sides began trading.

Klein used the roast meat as a bargaining chip again.

The process was similar to the last time.

This Gold-Digging Dwarf didn't have any good stuff on him.

Klein only exchanged five runes. 2 wind, 2 water, 1 earth.

And a special item.

The common language of the catacombs world!

It was a thick and unadorned book.

None of the words on it could be read.

It was like a distorted rune.

[The Common Language of the Catacombs World Rune Teaching Book: Created by an upright-walking crypt creature. It is suitable for most crypt creatures. After using it, one can immediately master the common language of the Catacombs World.]

Klein was holding the teaching book in his hands.

He raised his head and heard the Gold-Digging Dwarf going, "Abba abba." He kept gesturing as if he wanted Klein to learn.

"Use."

Klein recited silently.

In an instant, the light-colored patterns on the surface of the rune teaching book gradually lit up.

The Gold-Digging Dwarf clapped his hands in joy.

The rune teaching book transformed into rays of golden light that fused into Klein's brain.

Klein was slightly absent-minded.

A large number of strange symbols and sounds were inserted into his memory.

"Hey, hey, hey? Have you learned it?"

"Hey, can you understand what I'm saying?"

The Gold-Digging Dwarf kept waving his arms and shouting from a few meters away.

Klein snapped back to his senses and said with a faint smile, "I've learned it. It's not bad.

"Of course, the runic teaching book is a rare item. I'm only willing to give it to you because the meat you trade is very delicious! Most of the time, everyone needs to learn the common language bit by bit.

"It would take a few years to learn and finish the entire book."

The Gold-Digging Dwarf chuckled. "Look, can you give me the condiments you used just now?"

So there's a reason!

Klein smiled.

The last time he gave a bottle of black pepper to another Gold-Digging Dwarf, he went to the exchange channel to exchange for it.

"Alright, not only will I give you black pepper, I'll also give you a portion of chili noodles. It's not bad to sprinkle it on."

Klein handed over the black pepper and chili noodles and said with a smile, "It's fate that we met. Don't be in a hurry to leave. We're having barbecued meat tonight, so we can eat it in pieces."

It wasn't that Klein was hospitable, but he wanted to gather more information.

Information about the catacombs!

"No, no, no. Our race has a habit of leaving immediately after the transaction. Although your barbecued meat is delicious, I must abide by the rules passed down by the ancestors of the Gold-Digging Dwarf.

The Gold-Digging Dwarf quickly packed the items before tying the bag.

There weren't many good items left in the bag. Most of them were gold, silver, jewelry, or some food.

Klein recalled that the Gold-Digging Dwarf had left in a hurry. So that was the reason.

Even if the Gold-Digging Dwarf was greedy, it would still abide by the rules passed down by its ancestors.

"Before I leave, can I ask you a question? What is the entire catacombs world like?"

Klein spoke quickly, almost reflexively raising the question.

If the Gold-Digging Dwarf stayed behind...

He could ask about it in detail.

Time was tight, so the question appeared vague.

The Gold-Digging Dwarf paused and curled his lips. "The underground world is very large. Our current location is in the periphery. If you keep moving forward, you might be able to find the Underground City! Only in the Underground City...

"Can you see the civilization. There are only beasts in the periphery.

"I have to go."

The Gold-Digging Dwarf dug into the ground and disappeared in the blink of an eye.

"Underground City?"

Klein repeatedly pondered over the information the Gold-Digging Dwarf brought him.

Underground city civilization, periphery...

The amount of information was a little large.

"The periphery is filled with beasts? It looks like even if they're crypt creatures, there's still a chain of contempt."

Klein looked at Little Fox and Little Wind. The two little fellows didn't speak a common language.

When they communicated with each other, it was mostly through body language or tone.

Previously, he had naively allowed Little Fox to communicate with the Gold-Digging Dwarf. Both sides were probably speaking a different language. It was no wonder that he had to spend so much effort to understand it.

And the reason why his words could be understood by Little Fox and Little Wind was mostly because they were bound to each other.

The number of excavations tonight had been used up.

Klein spread out the base and camped at the same spot.

There was still some time before dinner.

Klein first went to the balcony to take a look. The Sweet Fruit had yet to ripen, but the Bread Tree had already blossomed!

'Looking at the situation, I can taste the Sweet Fruit tonight.'

Klein watered it and brought the fishing device outside.

Some minced meat had already been placed in the fish catcher as bait.

He dug a deep pit and buried the fish catcher.

"I wonder if I can catch a few more after being buried for a long time?"

Klein brought the shovel back.

On the way back, he thought of the runic honeycomb.

Now that he had enough runes, he could give it a try.

The roasted meat was dipped in honey, and it tasted pretty good!

On the balcony of the base.

Klein opened the manufacturing list.

[Perfect Runic Honeycomb: Wind Rune 3/1, Earth Rune 7/1, Wood 154/10, Iron 111/15]

Selection of manufacturing.

[System notification: Wind Rune-1, Earth Rune-1, Wood-10, Iron-15]

[System notification: Perfect Runic Honeycomb has been successfully constructed.]

A honeycomb-like device wrapped in iron plates appeared in front of Klein.

The interior was mainly made of wood.

There were some lines on the surface.

There was a hook at the top.

To operate, one needed to add a soul.

It operated for eight hours.

Klein added a soul and hung the runic honeycomb above the balcony.

There were flowers on the balcony.

If the Sand Bees were attracted, they could also be used locally.

Klein stayed on the balcony for a few minutes, but he didn't see a single Sand Bee. He couldn't help but doubt the efficacy of the device.

Or was it still on the way?
