Shui Bing'er didn't hesitate for long and immediately completed her Martial Soul Possession.
A pair of ice-blue phoenix wings unfolded behind her.
Her Second Soul Ring lit up simultaneously, and a thick layer of ice armor radiating a chilling aura immediately appeared on her body.
Despite Lin Mo's repeated reminders, Shui Bing'er, no matter how confident she was in her ice abilities, remained completely cautious.
After completing these preliminary preparations, Shui Bing'er nodded slightly to Lin Mo.
"Then let's go."
As Lin Mo spoke, he leaped into the cold spring and swam towards the source of the spring below.
Shui Bing'er followed closely behind.
The water temperature of the cold spring was extremely low; she could feel the biting cold as soon as she entered the water.
However, she is currently in a state of Martial Soul Possession and ice armor protection.
This temperature was nothing to her.
But... the further downstream you go, the more pronounced the chill becomes.
Even with the Ice Phoenix Martial Soul, she still couldn't help but feel the cold.
The chill was all-pervasive, penetrating directly through the ice armor and reaching deep into her skin, causing Shui Bing'er to shiver involuntarily.
Realizing this, Shui Bing'er became even more wary.
But Lin Mo in front of her seemed completely unaffected, moving around with ease.
A golden glint flashed in his eyes, and his Spirit Eyes constantly scanned his surroundings.
The enhancement of his Spirit Eyes allowed Lin Mo to see everything around him effortlessly, even in the dim underwater environment.
Before long, when they had descended to a depth of about thirty meters, Lin Mo used his mental power to Frisk a weak point in the rock wall.
A chill emanated from behind the rock wall, and it seemed to be a hollow cavity.
After swimming nearby, Lin Mo did not use his Soul Power, but instead unleashed a punch using only his physical strength.
The fist slammed into the rock wall, producing a dull thud. The rock wall shattered, sending debris flying in all directions.
The next moment, the spring water poured in, creating a powerful suction force.
Seeing that Lin Mo had allowed himself to be swept into the hidden space behind the rock wall, Shui Bing'er stopped using her Soul Power to resist and chose to let nature take its course.
The two were swept away by the current and rushed into the space behind the cavity.
Inside the cave.
Shui Bing'er got up from the ground, dusted herself off, and looked around.
"The temperature here is incredibly low; even the outer reaches of the Far North are much colder."
She exclaimed, her breath condensing into Mist in the air.
Shui Bing'er clearly sensed that the Ice-type Soul Power within her body, which was extremely close to the Ultimate Ice, Splash at this moment, circulating in her meridians much faster than usual.
Thinking of this, a hint of excitement flashed in Shui Bing'er's eyes.
It seems that coming down with Lin Mo was indeed the right choice.
The low temperature here alone makes the trip worthwhile; it will be very beneficial to my cultivation.
If I could stay here to cultivate for a long time, my Soul Power would probably improve very quickly.
It will be no less impressive than the time I spent training on Sea God Island!
"It's alright, I guess."
Lin Mo shrugged, glancing around at his surroundings.
Although the temperature here is cold, it's at most comparable to the temperature in the Extreme Cold Yin Spring.
The chill was still within his acceptable range; he could easily withstand it with his physical body alone.
The next moment, light elements gathered, and a wisp of light lit up Lin Mo's hand, illuminating everything around him.
The light wasn't strong, but it was more than enough to dispel the darkness in the cave.
With the help of this light, Shui Bing'er finally saw everything around her clearly.
The entire cave is composed entirely of various crystals.
These crystals are a deep blue color, crystal clear, and when illuminated by light, they are full of Mew colors.
"What... what are all these?" Shui Bing'er's voice was filled with barely suppressed surprise.
Following the call of her Martial Soul, she subconsciously moved closer to the ice-blue crystals.
The Ice Phoenix Martial Soul within her body emitted a strong Covet, urging her to approach the crystals.
She reached out and grasped one, feeling the joy emanating from it, and was momentarily taken aback.
This thing actually gave her a very familiar feeling; could it be alive?
A question arose in Shui Bing'er's mind.
" Ice Extreme Divine Crystal."
Lin Mo remained calm, his gaze sweeping over the surrounding crystals:
"This is an extremely rare Ice-type metal, a derivative product from the outer perimeter of the Ten-Thousand-Year Mysterious Ice Cavern."
"The only way to remove it is through the power of Ultimate Ice."
You should have felt it too; this thing is very beneficial to your cultivation. When we leave later, you can take some to create a Mimicry Cultivation Environment suitable for you.
Upon hearing Lin Mo's words, a deep sense of doubt flashed in Shui Bing'er's blue eyes.
His gaze lingered on Lin Mo, scrutinizing him intently.
Mingdu their first time entering, why was Lin Mo so familiar with this thing, even recognizing its name and function at a glance?
Also, Lin Mo's Ice-type ability has improved a bit too quickly, hasn't it? Has his ice immunity improved again?
Even this level of extreme cold couldn't affect him in the slightest?
During her experience on Sea God Island, Shui Bing'er witnessed firsthand just how exaggerated Lin Mo's dual immunity to ice and fire was.
Before she and Huo Wu could master the Ultimate Attribute abilities, they couldn't even harm Lin Mo.
In her opinion, elemental immunity was still too unfair.
It seems that Lin Mo's ice immunity has improved again; even Ultimate Ice cold cannot affect him.
Moreover, Lin Mo's method of resisting the cold was not based on her own fire, but on the same ability as her to manipulate ice.
Confirming this was incredibly simple; there wasn't the slightest fluctuation of fire element energy emanating from Lin Mo.
Shui Bing'er's doubts deepened, but she didn't press the matter further.
Lin Mo, seemingly oblivious to Shui Bing'er's lapse in composure, continued, "This place is truly a masterpiece of nature, requiring tens or even hundreds of thousands of years to form under such circumstances."
"Let's leave here first. These Ice Extreme Divine Crystal are just byproducts of the Mysterious Ice Cavern and are not worth mentioning."
You can retrieve it when you leave.
The real treasures are found in the Ten-Thousand-Year Mysterious Ice Cavern.
Lin Mo doesn't plan to take all the Ice Extreme Divine Crystal here for the time being; they are currently useless to him.
The primary function of Ice Extreme Divine Crystal is to serve as a rare metal in the manufacture of various weapons and Soul Tool.
However, given the current Soul Tool Technology in the Douluo Continent, let alone making it into a Soul Tool, even processing the Ice Extreme Divine Crystal is a major problem.
Ice Extreme Divine Crystal is very special; it is a top-grade rare metal that stands at the pinnacle of Ice-type.
To deal with it, the person handling it must possess the ability to freeze Ultimate Ice.
Moreover, the Soul Guidance Technology in the Douluo Continent has long since fallen behind, making it an impossible dream to turn it into Soul Tool.
Given the current situation on the Douluo Continent, it's impossible to master Soul Tool in the short term; playing with Hidden Weapon occasionally is more feasible.
If he really wants to play with Soul Guidance Technology, instead of climbing the technology tree from scratch, he might as well go through the trouble of making a trip to the Sun Moon Continent.
The Soul Guidance Technology of the Sun Moon Continent has maintained a stable lineage from beginning to end, and Soul Engineer are their mainstream. Their Soul Guidance Technology is far ahead of that of the Douluo Continent.
As for Hidden Weapon...
Lin Mo had already sent someone to Gengxin City, the metal capital, to invite Lou Gao.
With Lou Gao, the only remaining master craftsman, on board, the full potential of the Hundred Solutions to Hidden Weapon technique could be unleashed in the shortest amount of time.
Before diving down again, Lin Mo looked at Shui Bing'er behind him and reminded her once more, "You must have already sensed the cold air around us. What I said earlier was absolutely true."
Lin Mo paused here, his tone becoming even more serious, and pointed to the cave around them:
"The cold air and Ice Extreme Divine Crystal gathered here are only a small part of what has accidentally leaked out of the Ten-Thousand-Year Mysterious Ice Cavern over the years."
The temperature in the Mysterious Ice Cavern will be lower than here, possibly reaching the legendary Absolute Zero!
Absolute Zero.
These four words made Shui Bing'er's head tighten.
As Ice-type Soul Master, he knew all too well what Absolute Zero meant!
That is the ultimate expression of ice; it's no exaggeration to say that it's the ultimate goal pursued by all Ice-type Soul Master!
"I want to get off!"
Shui Bing'er nodded without hesitation.
She raised her head, her blue eyes filled with determination.
"Besides, aren't you right here? If I really can't hold on, you can just save me in time." There was a hint of Frisk in her voice.
Seeing that Shui Bing'er still insisted, Lin Mo stopped trying to persuade her.
He was ready to come to the rescue at any time. The Domain of Ice attached to the Ice Dragon King Left Arm Bone could, in a sense, be called the domain of a god.
For him, carrying out a rescue mission in the Mysterious Ice Cavern was no challenge at all.
"Then stick close to me," Lin Mo said.
Shui Bing'er quickly followed.
Soon, the two swam back to the original spring and headed towards the spring's source.
Upon arriving near the spring, Shui Bing'er clearly sensed that her Soul Power, which was extremely close to the Ultimate Ice, began to slow down due to the influence of the surrounding cold air.
This was the first time he had encountered such a situation, and he also realized that Lin Mo's earlier claim of Absolute Zero was indeed true.
The temperature inside that so-called Mysterious Ice Cavern below may indeed have reached near Absolute Zero!
Before long, with Lin Mo's protection, the two successfully entered the spring and continued to descend into the abyss.
Forty meters.
Forty-five meters.
Fifty meters.
The temperature dropped as they went down, Shui Bing'er's limbs began to Harden, her consciousness starting to blur.
She gritted her teeth and desperately channeled her Soul Power, trying to stay conscious.
But the chill was too intense, and her struggles were largely ineffective.
Shui Bing'er's unusual behavior caught Lin Mo's attention.
Realizing something was wrong, Lin Mo turned around and sped up, pulling Shui Bing'er into his arms to offer her some warmth.
Then, with a sudden burst of power, it accelerated downwards once more.
With a thud, the two fell into a small cave.
In an instant, an extremely terrifying chill entered Shui Bing'er's body, causing her to shiver deeply.
This chill was more than ten times stronger than before, making her feel as if her very soul was frozen.
This made her realize that the limit of ice was indeed the legendary Absolute Zero.
The power of Ultimate Ice at Absolute Zero would likely be terrifying, perhaps even freezing space and time.
The Ten-Thousand-Year Mysterious Ice Cavern.
The cave is very small, only fifteen square meters, and the average height is no more than one and a half meters.
This meant that Lin Mo, who was over 1.9 meters tall, could only stand up by slightly hunching over.
Shui Bing'er curled up into a ball, trembling as she leaned against Lin Mo's chest.
She greedily Absorb that little bit of body warmth, like a drowning person finally grasping at a straw.
Lin Mo did not rush to activate the Domain of Ice to provide assistance.
Instead, he carefully monitored Shui Bing'er's condition in his arms. After ensuring her safety and confirming that she had reached her limit, Lin Mo quietly activated his left arm bone.
A point of cold light emanated from Lin Mo and spread outwards, enveloping the entire cave.
The Ice Dragon King Left Arm Bone possesses Soul Skill: Domain of Ice!
Wherever the cold light passed, the terrifying chill in the cave, which seemed to freeze everything, was tamed as if it had met its nemesis, and became compliant in an instant.
Although the temperature inside the Mysterious Ice Cavern was still very low, it was no longer fatal.
With the support of the Domain of Ice, Shui Bing'er could still feel the chill around her, but it was no longer an insurmountable chill for her.
Lin Mo did this so that Shui Bing'er could personally experience the extreme cold, which was close to Absolute Zero, inside the Mysterious Ice Cavern.
This challenging experience will greatly benefit her future cultivation and her understanding of the Dao of Ice.
Otherwise, he could have released the Domain of Ice from the very beginning to protect Shui Bing'er throughout the entire process.
Before Lin Mo could loosen his grip on Shui Bing'er, she hugged him tighter again.
"Don't move yet, let me borrow a little more of your body heat..." Shui Bing'er buried her head in Lin Mo's chest, preventing Lin Mo from pushing her away.
After a while, her breathing gradually calmed down.
Only then did she lift her frostbitten little face and look at Lin Mo: " A-Mo, how did you know about this place?"
How did you know that such a precious treasure was hidden here?
Shui Bing'er couldn't hold back any longer and asked the question that had been bothering her.
After she finished speaking, she poked her head out and furtively looked around at the icicles.
She could clearly sense an unprecedented Covet emanating from the Ice Phoenix Martial Soul within her body.
Its intensity surpasses that of the metals Lin Mo had previously referred to as Ice Extreme Divine Crystal.
Shui Bing'er was absolutely certain that these pure white icicles were Lin Mo's true target for this trip.
Moreover, this item is of great benefit to Ice-type Soul Master.
If she could absorb even a little bit, her Ice-type, which was only one step away from the Ultimate Ice, would probably undergo a transformation on the spot!
