Klein had marked the place where the fishing device was buried.

He took out a shovel and dug down.

About two meters deep, he saw a square iron box.

It was completely khaki in color, similar to the color of the sand.

There were some patterns on its surface, and two symbols that were identical to the earth runes could be clearly seen.

Klein picked up the iron box, and sand constantly flowed out from the fine holes below.

There was an entrance to the front of this thing. Once the Sand Fish entered, they would be trapped inside.

To check if he had caught any Sand Fish, he could check through the peephole above.

Klein lowered his head and approached the peephole. As the sand inside decreased, he gradually saw some figures.

They were indeed fish!

There was more than one!

He carried the fishing device back.

He lifted the lid above and saw five different types of Sand Fish jumping around.

They did not smell fishy, and the smell of the soil was heavy.

Two of them had purple backs, and their fins were long.

The jades looked like fish, and their bodies were yellowish-brown.

Two of them were round, and their tails looked like hammers.

[System notification: Purple-Backed Sand Fish+2]

[System notification: Long Sand Fish+1]

[System notification: Hammertail Sand Fish+2]

Their names were simple and unadorned, and they were close to their physical characteristics.

[Purple-Back Sand Fish: Meat is fresh and tender and looks good. Current consumption of satiation index is 1 star, overall score 43.]

[Long Sand Fish: Meat is slightly smelly, no nutritional value. Soft mouth, toothless. Current consumption of satiation index is half a star, overall score 32.]

[Hammertail Sand Fish: Meat is chewy, rich in trace elements. Current consumption of satiation index is 1 star, overall score 45.]

The three types of Sand Fish, from satiation index to overall score, lagged behind the crypt creatures.

'I wonder if Sand Fish can give souls?'

Just as Klein thought of this, he had already chopped up the Purple-Backed Sand Fish.

The system didn't give him any feedback.

It seemed like not all crypt creatures had souls.

Perhaps it was because the Sand Fish were too weak.

Klein thought for a moment before saying, "Let's keep these fish for now."

Klein walked to a corner and beside the meat field. He used a slate to build a more spacious container.

He then poured sand into it and placed the other three Sand Fish down.

When the three Sand Fish touched the sand, they immediately dived down.

They seemed to have an affinity with the earth element similar to that of a Gold-Digging Dwarf, so the sand didn't pose much of a resistance to them.

Klein watched for a few minutes and sprinkled a handful of rice grains on top.

Occasionally, he could see the rice grains sink. They were probably dragged down by the Sand Fish and eaten.

'I wonder if anyone likes the Long Sand Fish? Let's try putting it up.'

Klein originally wanted to use the Long Sand Fish to make fertilizer, but after some thought, he decided to put it up on the trading market.

After all, it was a living thing.

So far, no one had placed a living thing in the trading channel.

Perhaps it was a rare commodity!

If some people were too lonely and didn't meet a player, they might need a pet to accompany them.

There were many people who raised fish in the real world.

In the trading channel.

[Seller: Klein 182.56]

[Trade Item: Long Sand Fish]

[Requirements: Any rune]

[Inventory: 1]

[Seller's message: Live fish. You can feed it by simply finding a container and putting sand in it. I suspect that it has good room for growth. It will be a good partner for you in the future.]

..

In order to increase the selling point, Klein casually made up a paragraph.

The Sand Fish was successfully put on the shelf.

Klein put away the runic base and set off for the abandoned Earth Dragon nest.

In less than half a minute.

The world channel was already discussing the matter of the Long Sand Fish.

"Holy shit, there's fish in the catacombs world?"

"Hahaha, I also just discovered that Big Brother Klein has a live fish put up. The description says that it's not delicious. If anyone is lacking a partner, they can buy it and keep it."

"Didn't you guys notice Big Brother Klein's message? This fish might be extraordinary! Who wants to lend a rune to me? I want to buy it and cultivate it."

"Hasn't Klein already domesticated crypt creatures? His seller's message has a certain level of trust."

"Why can't we catch Sand Fish? Does Klein have fishing tools or fishing techniques? Please tell us, Big Brother!"

"Did you hear? Someone met Big Brother Klein this morning. This fellow is too fierce. He killed a large spider with a single slash, just like Superman!"

"That's normal. I can even deal with crypt creatures. Big Brother will definitely have it easier. Don't look at Big Brother like an ordinary person. They're all very impressive. Big Brother Klein is one of the best."

"I'll buy that fish. It has temperature and is quite useful. Big Brother Klein isn't wrong. It can indeed help."

"???"

"There's a pervert among us!"

With just a live fish, Klein once again attracted attention and was hotly discussed by many people.

Even the matter of Klein saving the two players this morning was revealed.

Yesterday, Klein was still a sinister and terrifying figure, but today, he had become a big brother who helped out!

At this moment.

Klein was digging a tunnel.

With another shovel, a black membrane appeared in front of him.

Klein put away the shovel and patted the sand on his body.

[System notification: Long Sand Fish-1]

[System notification: Transaction completed. Wind Rune+1]

"Eh, so fast?"

Klein didn't expect that someone would buy it less than three minutes after it was put up.

It was indeed a rare commodity!

What surprised him even more was that the Long Sand Fish attracted buyers not because they could eat it, but more because the Long Sand Fish were alive...

The most important thing was that the Long Sand Fish did not have teeth.

It could be used to do many interesting things.

It could not be helped. Some people held back for too long and looked at everything with strange looks.
