The further south one travels, the lower the temperature becomes.
When the temperature drops to a level more suitable for human habitation, a smidgen of green trees come into sight, however sparse they may be.
In the vast majority of areas, whether they be hilly terrains or valleys, all are essentially desolate zones without a trace of life.
By this measure, the environment of this hidden world is slightly better than that of Mars in the solar system.
Michael and Yan Jiusi appeared in a location close to the polar south glacier. In just a few days, with their extraordinary eyesight, they could already see the endless glacier in the distance.
In Michael's line of sight, the bizarre imagery above the vault of the sky is more than twice as clear as before.
"It's not enough - Still not enough!"
The two continued to press forward, until they climbed atop the highest peak of the glaciers in the polar south.
Michael looks up at the sky, lost in thought.
