Although the sense of hearing and smell were also greatly obscured by the gray and cold air, they could still detect movements within two or three kilometers.
At the same time, Sulin also noticed a very unusual natural phenomenon inside the iceberg.
That is, the oxygen density here is also extremely high.
You must know that except for some alien species that can ignore natural conditions and break through the racial upper limit,
The size of most other species is linked to oxygen density.
Only the higher the oxygen density, the larger the animal will be.
So if there were any living species here, they would definitely be very big!
This made Su Lin's wolf eyes narrow slightly, and he still cautiously explored the iceberg.
There was nothing too unusual in the first four or five hundred meters into the iceberg.
I can just feel that the cold is getting heavier and heavier, and the inside of the iceberg is even more winding and rugged, like a maze.
Sulin could only rely on his keen sense of smell to follow the scent of the previous travelers and walk inside.
At this time, due to the slow gas circulation inside the iceberg.
He could already faintly distinguish the races these smells belonged to.
The wolf tribe, the bear tribe, and some lynx scents.
These lynxes were light in weight and did not leave traces on the periphery of the iceberg.
According to common sense, these species can indeed withstand severe cold, but the severe cold of minus 70 to 80 degrees can also cause very serious frostbite to them.
Unless these are all alien species!
When Su Lin thought of this possibility, he couldn't help but shook his head.
Alien species are still very rare, far from reaching the point where they are a waste on the streets.
Every alien species is a being with extremely strong growth potential in its own race. How could it possibly reach the point of ruining the streets?
Unless there is another possibility, it is a heterogeneous species formed by relying on pure energy.
The polar ice worm we encountered last time in an iceberg crevice is an example.
It's just that polar ice worms are small in size, so it doesn't take much pure energy to pile them up into alien species.
However, it is definitely not an easy task for the wolf, lynx and bear tribes to advance to the alien species simply by relying on pure energy.
To be honest, Su Lin has been feeding his cousin the flesh and blood of alien species these days, and he also wants to turn his cousin into a alien species.
When the energy in the body reaches a certain level, once the upper limit of race is exceeded, it will naturally evolve into a different species.
It's just obvious that this requires a lot of time and the intake of a lot of heterogeneous blood and flesh.
Next,
Su Lin didn't think any more and continued deeper into the iceberg.
The cold inside the iceberg is getting heavier and heavier, and the field of vision is getting smaller and smaller, but the hearing and smell have not been reduced much.
After entering the iceberg, the rugged ice road gradually goes downwards.
That is, leading to the inside of the ice.
The surrounding vision became darker and darker, but after Sulin walked another three to four hundred meters, he keenly heard the low howls of the wolves ahead.
The low howl was very weak, like a low-pitched communication, but it was still completely absorbed by Su Lin's ears.
"Huh? Ice monster? Destroy? What do you mean?"
Su Lin frowned slightly as he listened to the low howling of the wolves in front.
He could understand the meaning of these exchanges, but he didn't understand what they meant.
Are there ice monsters in the icebergs?
However, Su Lin thinks this may be because the wolves have low IQs, so they will naturally call unfamiliar species "weird".
He continued to walk forward, but this time the speed was slightly faster, hoping to pursue the wolves ahead.
Take a look at the wolves that can enter the cave. What kind of people are they?
By the way, let’s take a look at what they are discussing?
However, as Su Lin went deeper and deeper, his expression became slightly heavier.
Because he discovered that in the corner of the ice wall, there were a few scattered human corpses that had been frozen into ice sculptures!
Humanity!
This is almost the top of the North Pole!
There is no north direction here, because north has been stepped on.
At the same time, the cold temperature dropped to nearly minus one hundred degrees.
At such temperatures, even if humans rely on liquid nitrogen protective clothing, it will be difficult to survive for a long time.
After all, this is a temperature that can freeze steel into something as fragile as glass.
This made Sulin's eyes filled with curiosity. How could a human corpse appear here?
He used his wolf claws to peel away the snow and ice on the ice sculpture and took a closer look.
I found that these humans were wearing clothes from the last century.
Soon I saw the obvious Soviet Union logo on the protective clothing.
"Huh? Soviet alliance?"
Su Lin's expression softened.
As the absolute hegemon in the 1970s and 1980s, it is easy to understand that the Soviet Union once explored the Arctic Pole.
After all, the Arctic here borders the Soviet Union and is equivalent to the Soviet Union's back garden.
However, Su Lin is still very curious, what happened to the people of the Soviet Union here?
How come so many people died in scattered places?
Or was this once a research base of the Soviet Union?
As the former hegemon during the Cold War, the Soviet Union naturally conducted countless extremely secretive research and experiments.
When he was a human in his previous life, Su Lin was very fond of adventure.
Now that he saw traces of human beings in the huge iceberg at the center of the Arctic, his expression suddenly became lively.
This proves that his judgment is absolutely correct.
Whether it was the Soviet Union in the last century or the hunters who entered the iceberg before, it all symbolized that there was definitely something unimaginable inside the iceberg.
Su Lin did not hesitate and continued to go deeper into the iceberg.
As it goes deeper and deeper, the extraordinary energy swirling inside the iceberg becomes heavier and heavier, and the concentration of oxygen becomes richer and richer.
Breathing the rich oxygen, Su Lin felt that the cells in his body were much more active.
After he had traveled quickly for more than a kilometer, he finally approached the place where the howling of the wolf had just come from.
It was at this moment that Su Lin directly activated his concealment talent.
He still didn't know what was going on inside the iceberg, so naturally he didn't want to be exposed to so many hunters.
After the concealment is turned on, the body does not emit any fluorescence.
On the contrary, his figure gradually became transparent, and the aura all over Sulin's body gradually dissipated.
Within a few seconds, Su Lin's huge body of more than four meters was completely hidden, and his aura completely disappeared.
It was as if this space had never had any signs of life.
The sound came from a huge cave inside the iceberg, and Su Lin quietly touched it.
As soon as he entered, the scene in front of him shocked Su Lin.
Because in this cave, there are not just groups of icicles and broken ice everywhere as imagined.
Instead, what appeared in front of us was a very empty and huge palace in the ice.
This palace is very majestic and splendid, and there are many lifelike carvings on the palace.
In addition, there are many modern industrial research instruments under the palace.
It can be seen that people from the Soviet Union did conduct very secret experiments here.
As for whether this palace was built by the Soviet Union, Su Lin couldn't say.
Because the aura that this palace gave me was somewhat similar to the aura of the crystal coffin that I encountered before traveling through time!
