Train Survival: You're really trying to survive!

Regardless of the specific hypothesis, it suggests that this exploration is quite challenging.

Su Li looked around at her teammates and decided on the process for this exploration: "Instead of deliberately chasing the evil god, we will focus our energy on how to collect resources, spirituality, and life factors."

"Because of the characteristics of the mutated monsters, we will be active at night and hiding during the day this time. I will adjust the shift schedule later."

"While gathering materials, we can also take the opportunity to connect with the local culture."

Sun Lili tilted her head in confusion: "Didn't we say we wouldn't delve too deeply into the evil god?"

Sun Keke kicked her sister's shin. "Idiot, we can trade with them. Haven't you heard? Clean water, so-called holy salt, and all kinds of meat are luxuries here. We have plenty of those things."

“We can trade local specialty items and have others help us collect ores.”

Su Li nodded approvingly to Coco, "Coco is right. There's another point: they've lived in this sea area for so long and know a lot about monsters. We can exchange information about monsters, which is much more efficient than us wandering around trying our luck."

Next, we need to find that so-called Holy City.

"No rush, let's rest first, and then start collecting ore on that big island according to the route we set beforehand."

The train sped across the sea. Dawn broke, and the mutated monsters were no longer in the sea. The journey was very safe.

However, traveling on the sea surface is not very stable. In the morning, the sun shines on the sea surface, creating a temperature difference. The wind starts to pick up on the sea, and waves crash against the train, making it sway from side to side.

The colorless seawater slowly seeped onto the window, leaving a trail of watermarks on the glass.

As the sun fully rose, the watermarks dried, leaving layers of white salt on the window.

Inside the train, Song Mingyu and Su Li were working together to conduct experiments and modifications.

"The composition of the seawater has been analyzed."

Song Mingyu took out a list. "The composition is very different from the seawater on Earth. There's even a special substance. I extracted this substance and injected it into the slime, and the slime showed signs of mental damage."

"I have verified the properties of this substance, and they are recorded in this document."

"In other words, as long as we solve this problem, we can extract the so-called holy salt," Su Li guessed. "I wonder how the locals extract it."

Zuli picked up the component analysis kit and found a sample containing this special substance.

After this special substance is extracted, its concentrated form is a slightly bluish substance that resembles water. Su Li guessed that under moonlight, this substance would probably become viscous, just like yesterday's seawater.

Can salt be directly synthesized industrially?

"I'm afraid we don't have that technology. Don't forget this is a level 1.2 world, where everything is imbued with magical energy. We don't yet have the ability to artificially create salt with magical energy."

"Can you solve the problem of extracting the holy salt?" Su Li couldn't help but ask.

“No.” Song Mingyu shook her head. “The extract I made contained too many impurities.”

"Then let me do it."

Su Li walked to the item retrieval point and browsed through the material list. Before long, he found the item he wanted.

Zuli picked up the seawater sample and went to the workbench in the laboratory.

He first verified the properties of this special substance.

[It has a tendency to target living matter with a soul, and carries a faint trace of magical energy. Try this idea.]

Su Li took out a small amount of GX virus, spread it on a petri dish, and then added nutrient solution. The GX virus has a very strong reproductive ability, and soon a layer of yellow-black virus grew in the petri dish, which looked very glaring.

Then, Su Li took out a mental-type monster crystal core and began to modify it. She pulverized the crystal core and then applied the powder to the virus according to a certain rune pattern.

Next, he tried to activate the runes with magical energy.

The runes activated, and a faint mental fluctuation emanated from the virus. He used the runes to simulate the thought processes of a small animal.

Su Li took out a bottle of seawater, placed it on top of the petri dish without opening it.

Under instrumental observation, the special substance inside began to gather towards the petri dish.

"Okay, next is the filter membrane. Using magic recognition techniques."

Taking out a slime's stomach pouch, Zuli then began concocting a magic neutralizer. Slimes have specific dietary preferences. As slimes evolve, they become increasingly inclined to eat certain foods, and the stomach pouch helps them absorb these specific foods.

Taking advantage of this characteristic of slimes, alchemists can use alchemical potions to modify the slime's stomach, making it an excellent filter membrane.

What Su Li took out was the stomach of a pure slime. This was the slime that Song Mingyu had cultivated through generations of iterations. It was the most fundamental slime, untouched by any elemental contamination, a species that could only survive in a laboratory. Its materials were extremely sensitive to various magical energy processing methods.

After carefully processing the slime's stomach, Zuli solidified it, transforming it into a long tube.

Next, take out a glass jar, insert the gastric tube into it, connect water containers at the top and bottom, put a large amount of GX virus into the glass jar to maintain the activity of the GX virus, and inscribe mental runes on it.

Su Li brought in a bucket of water from outside and poured the seawater into the container above.

Seawater flowed through the pipes into the glass tube containing the GX virus. The internal gastric sac duct was very long, and the seawater flowed slowly inside. Influenced by the external life force and mental fluctuations, the pollutants inside swam around and successfully passed through the gastric sac duct into the GX virus solution.

Below, the refined seawater flowed out. Su Li collected some seawater and conducted tests. 80% of the pollutants had been separated out.

Zurich then constructed several more devices to filter the seawater three more times after the first filtration. Finally, 97% of the pollutants were removed.

"I don't know if it will work." Su Li held the slightly bluish salt in her hand. "Let Jiao take a look later."
