Li Yan's other guess was that the cultivator who had once discovered the Polar Ice Heart was the Blood-Eyed Toad himself.
Naturally, he had wanted to obtain a better Polar Ice Heart at the time. But after suffering grave injuries, he had needed to rely constantly on the Ghost Domain to heal.
He could no longer visit the North Ice Continent in the Mortal Realm himself. If that was the case, he could certainly be sure that the Polar Ice Heart there would be difficult for anyone else to discover and take away.
After searching for so many days, Li Yan had seen quite a few similar ice crystals, but examining them one by one revealed that they were all perfectly ordinary.
It was only because they lay in the deep, freezing reaches of the glaciers that their shapes and the strange chill they radiated closely resembled the descriptions of the Polar Ice Heart.
As a result, Li Yan had to rely on the method the Blood-Eyed Toad had provided to identify each one bit by bit. His search could hardly proceed quickly.
This glacial ravine was also unfathomably deep. After observing it for a while, Li Yan turned into a wisp of smoke and swiftly descended.
Li Yan dodged the red arcs of lightning falling through the air. Above the glacier, great quantities of those red arcs and snowflakes were still falling.
But as Li Yan continued to descend, the terrifying winds below dragged the snowflakes and red lightning in particular directions, leaving many clear patches.
Whenever the wind abruptly shifted with the terrain, the falling snowflakes and red lightning changed direction with it.
These shifting winds were why every part beneath the glacier remained covered in snow, but they also opened up certain clear areas for Li Yan.
