This kind of enhancement made Su Lin feel very satisfied.
He looked at the remaining vial of Strengthening Serum and took it out again!
Su Lin''s tolerance for pain had be very strong,
which led him to decide to bite the bullet and use the second vial of Strengthening Serum as well.
"Ding! Do you want to use the Strengthening Serum?"
"Use."
As the scalding energy from the serum emerged once more, Su Lin felt that the pain was much more intense than the first time.
But it was still within his tolerance.
Clenching his teeth tightly, he endured it.
This time, the scalding energy moved quickly, not as slow as when it fortified his meridians.
In no time at all, it surged towards Su Lin''s lungs.
An extreme pain erupted from his lungs suddenly, making it somewhat difficult for Su Lin to breathe.
The feeling of suffocation made his vision darken.
But he could feel his lungs, which had undergone gic restructuring at the bottom of the cial crevice, breaking through gic shackles once again and undergoing new changes.
After strengthening his lungs, it seemed that in the future, not only could he roam onnd, but he could also swim under the water.
Especially in the ocean, there were countless species he had never feasted on, which was extremely tempting to Su Lin.
Thinking of the massive Evolution Points in the ocean, the pain in Su Lin''s lungs seemed to fade away significantly.
As his lungs subtly strengthened during this process, time also slowly passed by.
This time, the strengthening took clearly less time, requiring only about an hour or so for his lungs to be fully enhanced.
Su Lin then released the wolf teeth he had been biting down on, now feeling that his breaths were longer and his lungs possessed powerful vitality.
Following that, a new attribute page popped up once again.
But this time, the enhancements umted by fortifying his lungs only added 30 points to Endurance, far less than what he gained from strengthening his meridians.
However, the main benefit of strengthening the lungs was their enhanced breathing capability.
This would allow Su Lin to breathe underwater just like the Pr Bear.
The future hunting of various marine species was no longer a dream.
At this moment, Su Lin stood up, his massive wolf body moving towards the entrance of the cave.
Gazing at the snowy Arctic Tundra, he felt his significantly increased strength.
He couldn''t help but let out a long howl to vent the joy in his heart.
"Awooo!"
The clear and lingering howl of the wolf echoed through the cold Arctic sky.
Xiao Hui and the Pr Bear Cub were awakened from their sleep by Su Lin''s howling.
Both of them ran over to Su Lin''s side, their tails wagging.
After days of interaction, the Pr Bear Cub no longer felt estranged from the Wolf Pack.
It had grown familiar with all the members and had be integrated into the Wolf Pack.
Furthermore, with the Variant Species'' powerful learning ability, the Pr Bear Cub, through careful observation, could roughly understand what certain actions meant within the Wolf Pack.
In this period, it started to emte them with diligence.
Although the actions were clumsy, they brought a touch of joy to the Wolf Pack and allowed for some simplemunication through gestures and behavior.
Xiao Bai''s growth was also rapid, already reaching the mid-stage of Level 3 Variant Species in a short time.
This rate of growth was quite frightening.
However, it only took two to three years for an ordinary Pr Bear to grow to adulthood,
and the growth rate of Variant Species Pr Bears was even more rapid, not to mention that in recent days, Xiao Bai had consumed about ten pounds of Variant Species Flesh.
So, having such a growth rate was within the realm of reason.
Perhaps in a few more months, it would be able to hold its own within the Wolf Pack.
Now in the cave,
Wolf Sister, Grey White Little Wolf, and Xiao Bai also asionally engaged in yful tussles.
Initially, Wolf Sister''sbat strength was the strongest of the three.
After all, she had taken a dose of Potential Potion during her cub days, which gave her an edge in developing her bodily potential.
But recently, she could no longer suppress Xiao Bai.
Xiao Bai''s formidablebat strength as a Variant Species Pr Bear was gradually starting to show.
Su Lin looked at Xiao Hui and Xiao Bai as they approached and then took the two of them out of the cave.
As of now, hisbat power was unmatched in this region.
Looking over this area of three to four hundred miles, apart from the Variant Species Grizzly Bear that had gone elsewhere, there was not a single Hunter who could take a few strikes.
Even the Pr Bear, known as the Arctic Overlord, would struggle to withstand even a few rounds under Su Lin''s Wolf ws.
With an Attack Power of nearly four hundred on his right paw, a precise hit could easily bleed a Pr Bear''s hefty Vitality Value and life force dry!
This did not mean that the Pr Bear''sbat strength had weakened.
But after the great changes in the world, the natural kingdom no longer belonged to ordinary species.
This was the world of Variant Species!
As for ordinary species, even the once mighty Pr Bear would eventually be a fleeting memory in the era of great change.
After stepping out of the cave, Su Lin, apanied by Xiao Hui and Xiao Bai, headed towards the icy surface.
Having just strengthened his lungs, he naturally intended to hunt some prey on the ice.
...Pfft...Pfft...
Su Lin''s robust Wolf ws stepped on the snow, producing a subtle sound.
With his current size of four meters, he had long given up on stealth hunting skills such as stalking and hiding.
The low shrubs and bushes of the Arctic were simply insufficient to conceal such arge body.
Su Lin thus emerged onto the ice with dignity, leading Xiao Hui and Xiao Bai out!
He nned to first hunt some Seals, having long craved their plump and delicious flesh.
But Seals were intelligent and highly sensitive to the scent of danger, always staying near the ice holes and ready to leap into the sea at the first sign of trouble, which makes them difficult to capture.
