At the same time, Su Lin also noticed a very unusual natural phenomenon inside the ice mountain.

That is, the oxygen density here was also extremely high.

You should know that apart from some variant species that can ignore natural conditions and break through racial limits,

the size of most species is linked to the density of oxygen.

Only when the oxygen density is higher, will the size of the animals be bigger.

Therefore, if there are living species here, their size must be very large!

This caused Su Lin\'s wolf eyes to narrow slightly, and he continued to explore the ice mountain with great caution.

The first four to five hundred meters upon entering the ice mountain weren\'t too abnormal.

It was just that the cold seemed to be getting heavier, and the interior of the ice mountain was winding and rugged, resembling a labyrinth.

Su Lin could only rely on his keen sense of smell, following the scent of those who had gone ahead.

At this time, due to slow air circulation inside the ice mountain,

he could faintly distinguish the species of the various scents.

Wolf Clan, Bear Clan, and some lynx scents.

These lynxes, being lighter, had not left traces on the outer perimeter of the ice mountain.

Logically speaking, these species indeed could withstand the cold, but temperatures of minus seventy to eighty degrees could also cause them very serious frostbite.

Unless they were all variants!

Upon thinking of this possibility, Su Lin couldn\'t help but shake his head.

Variant species were still quite rare, and they were far from being commonplace.

Each variant was a being with great potential for growth within their own species, how could they possibly become commonplace?

The only other possibility was that they were formed from pure energy.

Last time in the crevices of the ice mountain, the Polar Ice Worm he encountered was an example.

However, Polar Ice Worms were small and didn\'t require much pure energy to become variants.

But for the Wolf Clan, lynxes, and the Bear Clan, ascending to a variant purely through pure energy is definitely not a trivial matter.

Honestly, during this period, Su Lin had been feeding his cousin variant species flesh, also trying to turn her into a variant.

Once the energy within the body reached a certain level, a breakthrough beyond the racial limit would naturally lead to evolution into a variant.

It was quite clear that this required a significant amount of time and the ingestion of large quantities of variant species flesh.

Next,

Su Lin didn\'t think any further but continued to delve deeper into the ice mountain.

The cold within the ice mountain was becoming heavier, and the visible range was getting smaller and smaller, but his hearing and sense of smell were not reduced by much.

After entering the ice mountain, the rugged icy path gradually sloped downward.

That is, toward the inside of the ice layers.

The surrounding visibility became darker and darker, yet after walking another three to four hundred meters, Su Lin keenly heard a low howl from the Wolf Clan upfront.

The howling was very faint, as if whispering something, but Su Lin heard it clearly.

"Hmm? An Ice monster? Destroy? What does that mean?"

Su Lin, listening to the low howls of the Wolf Clan ahead, frowned slightly.

He could make out the meaning of their communication but did not understand what they were talking about.

Could there be ice monsters within the ice mountain?

Su Lin thought it was nonsense; it could be that the Wolf Clan, with their lower intelligence, naturally labeled any unknown species as "monsters."

He continued to walk forward, though this time he quickened his pace a bit, wanting to catch up to the Wolf Clan upfront.

To see what sort of creatures from the Wolf Clan could make it into the cave,

and also to see what exactly they were discussing?

However, as Su Lin ventured deeper, his expression became slightly somber.

Because he discovered that in the corners of the ice walls, there were scattered human corpses that had been frozen into ice sculptures!

Humans!

This place was almost the very pole of the Arctic!

```

There is no north here because north has already been trampled underfoot.

Meanwhile, the bitterly cold temperature has dropped to nearly minus one hundred degrees.

Such temperatures, even with the aid of liquid nitrogen protective suits, are difficult for humans to survive in for long.

After all, this is a temperature at which even steel can become as brittle as glass.

It filled Su Lin\'s eyes with curiosity—how could human bodies appear here?

He brushed away the snow and ice on the ice sculpture to take a closer look.

He found that these people were dressed in clothing from the last century.

Soon, he saw the very obvious Soviet Union emblem on the protective suits.

"Hm? The Soviet Union?"

Su Lin\'s expression eased.

As the absolute dominator of the seventies and eighties of the last century, it was easy to understand that the Soviet Union had once explored the Arctic Heart.

After all, the Arctic bordered the Soviet Union, equivalent to its backyard.

But Su Lin was still curious, what had happened to these people from the Soviet Union back then?

Why were there so many people who had died in such a scattered manner?

Or was this once a Soviet Union research base?

As the absolute dominator of the Cold War era, the Soviet Union naturally conducted countless highly secretive research and experiments.

In his previous life as a human, Su Lin had always been fond of exploration.

Now, upon seeing traces of humans within the massive iceberg at the Arctic Heart, he immediately became excited.

This proved that his judgment was absolutely correct.

Whether it was the Soviet Union of the last century or the Hunters who had entered the iceberg before him, both signified that there must be something unimaginable inside this iceberg.

Su Lin did not hesitate and continued to delve deeper into the iceberg.

The deeper he went, the stronger the extraordinary energy surging within the iceberg became, and the richer the concentration of oxygen.

Breathing in the rich oxygen, Su Lin felt the cells in his body become much more active.

When he had rapidly traveled for over a kilometer, he finally approached the place from where the howl had originated.

It was at this moment that Su Lin activated his Stealth Talent.

He still didn\'t know what exactly was inside the iceberg, and naturally, he didn\'t want to expose himself to the numerous Hunters.

After activating Stealth, he emitted no fluorescence.

Instead, his figure began to grow translucent, and his presence gradually faded.

In a few seconds, Su Lin\'s massive body over four meters tall was completely concealed, and his presence completely vanished.

It was as if this space had never witnessed any sign of life.

The sound came from a huge dissolving cave inside the iceberg, Su Lin quietly sneaked in.

No sooner had he entered than he was shocked by what he saw.

Because the cave didn\'t just contain ice pillars and ice shards as he had imagined.

Instead, what appeared before him was a vast and magnificent ice palace.

The palace was grand and splendid, and there were many life-like sculptures on it.

Beyond that, there were also quite a few modern industrial research instruments underneath the palace.

It was clear that the people from the Soviet Union had indeed conducted very secretive experiments here.

As for whether the palace was built by the Soviet Union, Su Lin could not be certain.

Because the aura of the palace gave him a feeling somewhat similar to the Crystal Coffin he had encountered before his time travel!

It was at this moment that Su Lin suddenly remembered the complex script on the Crystal Coffin.

"Ice Age, great changes of heaven and earth, species evolution, and the resurgence of Divine Demons!"

Upon thinking of the last piece of text, he couldn\'t help but take a sharp breath!

Divine Demons resurgence!

If that were true, then what\'s the point?

All species between heaven and earth, even those who claim to possess peak technology like humans, would still have to make way for Divine Demons, wouldn\'t they?

However, fortunately, Su Lin soon suppressed this shocking and outrageous thought.

After all, it was too inconceivable!
