Chapter 74 Architectural Skills

Sure enough!

Su Jin's lips curled up slightly; his guess was correct.

In fact, even if it costs a bit more, this deep-sea pearl is still a sure thing.

Even if it cannot be used as a material for skill slots, it can be turned into a simple seawater desalination device through physical means.

Now it's even better; if it becomes a skill, it can play a much greater role.

Without delay, Su Jin immediately embedded the special deep-sea pearl into his skill slot.

A flash of white light, the pearl disappeared, and the next second, he obtained the specific skill information.

[Water-Salt Separation Device: A construction skill that separates salts from contacting salt water.]

[Note: Because the carrier itself is a deep-sea salt-eating mussel pearl, some of the separated salt will be lost to maintain the carrier's vitality.]

Upon seeing the skill description, Su Jin was not surprised and was quite satisfied.

This is the effect he wanted: a seawater desalination device, and he even specialized its effect in the skill slot.

The process has changed from simply absorbing salt to precipitating salt, which means that he can obtain salt without going through such complicated procedures.

This is the first seasoning they've obtained so far, and it will make it easier for them to consume salt from now on.

The water-salt separation device was installed in the aft cabin, in the very spot that was being used as a storage room.

This is where the advantage lies: there is a cover at the bottom of the cabin that can be opened, allowing seawater to be taken directly from the bottom of the ship and filled into the device, which is very convenient.

Su Jin arrived at the rear cabin and quickly found the device, which was only one meter tall and about the size of a water tank, in the corner.

The device was actually quite simple; it was just a square water tank with a miniature clam pearl inlaid on the edge of the tank.

The original version was the size of a basketball, but now it's only the size of a fist.

Behind this pearl, there is a small wooden box, which is probably where the precipitated salt is stored.

Now that the device has become smaller, he wanted to see if its dilution efficiency would change as a result.

Just then, he heard a voice behind him, and without a doubt, it was Lin Xuan who had followed him down.

The female college student had already eaten a little. She had just seen Su Jin excitedly walk past her and go down to the rear cabin, so she followed him down.

"Captain...do you need my help?" she asked proactively.

She's a woman of action. No matter what happens later, she joined the ship first, so they're now a collective.

She felt obligated to do something to make the ark stronger.

Su Jin didn't expect Lin Xuan to come down with him, but it didn't matter, it was good that he didn't have to lift a finger.

"See this tank? Open the cover next to it, fill the tank with seawater using a wooden bucket, it's that simple."

He pointed to the water-salt separation device, and then to the cover plate next to it.

Lin Xuan nodded, not knowing what use it was.

But she was used to being a graduate student, and she would do whatever her supervisor told her to do, so when Su Jin gave an order, she would just do it.

Although she was still a bit weak, she could still manage to fill the tank with water if she gritted her teeth.

Even with such simple labor, she was left with pale lips and sweating profusely afterward.

Su Jin saw all of this and shook his head inwardly, thinking that college students' physical condition was really not good.

However, he was quite satisfied with Lin Xuan's ability to take action; obedient people are never disliked.

He patted Lin Xuan on the shoulder and said with a smile:

"You look weak. Tonight, I'll have Yuanyuan cook you some good fish soup and some golden fish roe. You can try it too, to help you recover."

After being patted on the shoulder, Lin Xuan subconsciously took a step back and looked at the spot where she had just been patted with great concern.

However, the thought of having a full meal that night made her subconsciously swallow, but this did not prevent her from keeping a certain distance from Su Jin.

Su Jin didn't notice this small detail; his attention was focused on the water-salt separation device in front of him.

The seawater in the tank didn't look any different; it was still that murky, pale blue.

But upon closer inspection, the surface of the miniature pearl was emitting a faint white light, with the light and dark alternating rhythmically like breathing.

The seawater in the tank flowed towards the pearl at a slow pace, almost imperceptible to the naked eye, as if drawn by some invisible force.

Time passed little by little.

About ten minutes later, just as Lin Xuan was wiping the cold sweat from her forehead, leaning against the cabin wall to catch her breath, wondering what the strange water tank was for, Su Jin suddenly moved.

He bent down and approached the small wooden box behind the sink that connected to the deep-sea pearl.

The opening of the wooden box was very narrow. He stretched out his finger and carefully dabbed something out from the edge of the opening.

Lin Xuan subconsciously looked over.

On Su Jin's fingertips were some very fine white crystalline particles, and they were slightly damp.

"It's done." Su Jin said in a low voice, his tone carrying a hint of "I knew it."

He turned around, and instead of trying it himself immediately, he stretched out his fingers, which were covered in white crystals, in front of Lin Xuan, almost touching her nose.

"Hey, aren't you a chemistry major? Try it and analyze it?"

Su Jin's tone was very natural, as if he were asking a classmate in the lab to help confirm the product.

Lin Xuan was startled by the finger suddenly extended in front of her, and instinctively shrank back, her back pressed against the cold wooden board.

Her cheeks felt a little hot because the distance was... too close.

Moreover, it was handed over directly with fingers covered in some unknown crystal...

But she was quickly drawn to the white crystals, and upon closer inspection, she recognized what they were.

"This is... salt?"

Her tone was tinged with surprise, and then she looked again at the strange water tank, especially at the unusual little clam pearl.

It's obvious that this is what made it. Could it be that it extracted salt from seawater?

Lin Xuan was a little surprised; she hadn't expected such a magical thing to exist.

Su Jin nodded casually, but his arm was getting a little tired from holding it up, so he urged:

"Try it quickly and see how pure it is!"

Lin Xuan blinked at the calm Su Jin. Theoretically speaking, tasting is indeed one of the most direct methods to determine the purity of salt and whether it contains harmful impurities under rudimentary conditions, but...

Licking a strange man's fingers, that's just too much...

Her face flushed even more, and her eyes inadvertently darted away.

But what the man said did make sense, and this was also the first time she had been assigned a task related to her profession since boarding the ship...

We can't afford to fail!

She took a deep breath, suppressing the awkwardness and shame in her heart, and forced herself to focus her attention on the crystals.

She tilted her head slightly to avoid looking directly at Su Jin's fingers, then carefully leaned closer and gently licked the damp white particles.
