National destiny: Starting with a coffin, building an aircraft carrier is broadcast live globally.

The ship's biological purification system can only produce 0.6 liters of fresh water per day.

Forget taking a bath, even washing my face is a luxury.

This is under the premise that Ivan only drinks alcohol and not water every day.

Using this bathtub for a bath would take forever.

Reason ultimately prevailed over obsessive-compulsive disorder.

Klaus looked away with difficulty:

"……No."

"So," Randomly placed his hand on the cold edge of the bathtub, "what use is it besides taking up space?"

Decomposeヾ(￣▽￣)Bye~Bye~

"No—!" Klaus let out a short, mournful cry.

The luxurious golden fish tank vanished in a flash, turning into specks of light in Ivan and Klaus's reluctant gazes.

"Boss..." Ivan swallowed hard.

"That's... pure gold..."

Who doesn't like gold?

Looking at the 100 units of gold and 20 gems in the warehouse, I felt quite pleased.

"Once we no longer lack water, we'll build an even bigger and more luxurious one."

Klaus was still grieving the loss of his duck, his shoulders slumped as he continued to fit teeth into Katyusha.

[Hahaha, this guy is amazing!]

[Klaus: My heart is shattered like a bathtub.]

[Don't ask, it's useless to ask. It's only useful when broken down into materials!]

However, this time we have made a judgment about the mysterious neighbor of this sea area.

It likes rotten flesh and blood, and is very polite.

They know to compensate for broken items and even accept barter.

This business... is doable!

The frustration of the broken fishing rod vanished instantly; a neighbor who is willing to trade, powerful, and reasonable is a rare find.

Their relationship could be described as "becoming friends after a fight".

He randomly took out another piece of rotten flesh and hung it on the hook, but did not throw it down immediately.

"Boss, what else do you want to exchange?" Ivan asked curiously.

"I want to change..."

He paused for a moment, but spoke to the sea.

"A creature that can purify water... is someone who will clean up for you."

[Is the big shot making a wish upon the ocean?]

[Wait, what the heck is "cleaning"? Are you asking the fish to clean?]

[This scene is too beautiful to imagine, a group of fish carrying rags and wiping themselves on the boat...]

[The Snail Maiden?]

[It must be the Conch Girl!]

In fact, any purification or cleaning is simply about eating impurities and then expelling clean water. For marine life, isn't that just like cleaning?

I don't know if that mysterious being can understand it, but that doesn't stop me from giving it a try.

He cast the fishhook, still covered in blood and flesh, into the sea and waited quietly.

Time passed slowly, and this time the reaction was much slower. It took a full ten minutes before the rope in Renyi's hand was gently tugged.

Ren Yi's spirits lifted, and he eagerly pulled the rope back.

Klaus, who was repairing the ship nearby, couldn't help but peek out, clearly eager for the "purified water" traded for.

What surfaced changed Klaus's expression from anticipation to horror.

"Ծ‸ Ծ Bugs?!"

The thing was over a meter long, pinkish-white all over, and had a round "mouth" that kept opening and closing. It wriggled and folded in the water, its shape...

It's hard to describe.

Anyway, it does challenge the aesthetic bottom line of both Renyi and Klaus.

[Holy crap, is that a sea cucumber? It's huge! ヾ(ﾟ∀ﾟゞ)?!]

[...This should probably be called dragon intestines...]

Why do I feel a little... astringent? Is something wrong with me?

[The "water purification thing" that the expert wanted, could it be used for...filtration?]

Ivan, being bold, curiously poked it, and the thing started to wriggle, spraying water from its "mouth" at the front, splattering Ivan's face.

"Ptooey...salty..." Ivan wiped his face and said.

Klaus, his face pale, moved further away from Ivan... (⊙＿⊙；)

The system panel pops up as needed.

[Decomposable target detected: Mutant giant sea cucumber (Rare)]

[Decomposition yields: 1 bioactive filter membrane, 8 highly elastic intestinal tissues]

[Confirm decomposition?]

"break down."

The giant pink insect instantly turned into specks of light.

[Activated filter membrane: A rare biomaterial with amazing molecular sieving capabilities, it can efficiently filter impurities and salts.]

[Review: A miracle filter from nature. PS: Its former owner used it for filtering... well, you wouldn't want to know.]

The mysterious creature could indeed understand him.

He immediately opened the evolution panel.

[Biological Purification Device (LV.0) > Biological Purification Device (LV.1)]

[Function: Converts seawater into potable freshwater through a symbiotic membrane structure. Current daily production: 0.6 liters.]

[Evolutionary Requirements:]

【1. Activated Filter Membrane (1/1)】

【2. Evolution Points (33/10)】

"evolution!"

[Evolution successful!]

[Biological Purification Device (LV.1)]

[Function: Converts seawater into potable freshwater through a symbiotic membrane structure. Current daily production: 5 liters.]

[Comment: Congratulations, you can finally pretend you live in a civilized society. P.S.: Don't sing too loudly.]

As it evolved, the sea anemone, which had originally resembled a bowl, shrank back into its original shape.

Transparent tentacles slowly grew from the outer wall of the captain's cabin. They twisted together and eventually formed a small, translucent wine barrel that looked like it was hanging on the wall.

Through the container, you can clearly see the honeycomb-like veins inside, pulsating slightly with each breath.

A small section of coral bone protrudes from the bottom of the barrel, serving as a switch.

Five liters.

Klaus whirled around, "How much?! (๑ŐдŐ)b"

"Five liters, every day."

Klaus excitedly spun around twice, rushed to the 'barrel', and touched the coral bone switch.

A stream of clear water immediately gushed out.

It tastes the same as before, just like regular bottled water.

But when his gaze fell upon the spot where the golden bathtub had vanished, joy was immediately mixed with heartache.

"......tub......"

"Hahahaha..." Ivan and the viewers in the live chat laughed loudly together.

Going from 0.6 to 5 liters is a huge leap.

With the enhanced efficiency of the ruminant digestion module, they can now enjoy freshwater freedom starting today!

The harvest this time far exceeded expectations.

Seeing that the two were still excited, Ren Yi decided not to continue the transaction with this mysterious neighbor.

"Boss, shall we go again?"

Ivan's eyes lit up when he saw that Ren Yi had pulled out another piece of meat.

"I'm not changing it."

"what?"

Why did you suddenly stop?

Without explanation, Renyi simply took out several more pieces of uneaten crab meat from the system warehouse and threw them into the sea.

"It's a gift for it."

But Ivan and Klaus were clearly puzzled.

In their view, these were clearly valuable bait to be exchanged for resources.

Why give it away for free?

"Boss, isn't this... such a waste?" Ivan felt a little sorry for them.

"This is not a waste; our neighbors deserve this kindness."

He said softly.

They still don't know what this mysterious creature is thinking.

If you exchange too many, it will become satisfied and stop trading.

Or, on second thought, one might realize that these humans' insatiable greed is a recipe for disaster.

It's foolish to try and squeeze every last drop of value out of someone.

Giving appropriate support to maintain a good relationship will yield greater results.
