The area with the rising temperature up ahead is a Gobi in the Liu River region, which has sparse vegetation and features exposed sandstone everywhere.
This Gobi is not very large, with a diameter of less than two kilometers, and there is a sandstone hill in the center.
Lu Heng and his group were preparing to enter the central area of the Gobi.
Suddenly, Su Muyu stretched out her hand, pointing ahead, and said urgently, "A signal flare! There's a signal flare over there."
Due to the fog, the visibility during the day is less than ten meters, while the thickness of the fog can reach three hundred meters.
Therefore, Superpower Users without the Perception Skill cannot see the signal flare in the fog.
Looking up at the sky, one can't even see branches ten meters high.
Therefore, only Perceivers can see the signal flare.
Su Muyu had her scouting eagle flying outside the fog to scout, so she was the first to notice the signal flare.
