Betrayed by a tree!?

A certain snowfield in an unknown place.

In each direction you look you can only see snow. In all directions the snow can be seen scattered to the horizon, while the sky continuously pouring more snow on the ground.

A young man with black hair and black pupils can be seen walking with a slow pace, he is obviously having difficulties crossing this snow. Sometimes he suddenly stops walking and as if avoiding something takes a small detour then continues to walk in the same direction.

And sometimes he uses his skill to instantly cross over a huge area.

After continuously walking for who knows how long, he found a dried up tree covered in snow. The boy first inspected around the tree and when he was fully sure he sat beside the tree and started to recover his mana, which he needed to do urgently.

The winds are chilly enough to froze your lungs if you inhale them. Eventually you will die due to lack of breath. A miserable death indeed.
