"Oh my God, what is that black mist?" Lina exclaimed in shock.
Suddenly, a massive cloud of black mist appeared a hundred meters away from the three of them, thick like fog and incredibly dense.
It stretched far into the distance, dark and ominous, with no end in sight, covering the entire horizon and continuing to approach!
Lina and Shirley both frowned, feeling an overwhelming sense of danger emanating from the dark mass.
"Woof, woof!" Buddy also stood alert, instinctively on guard.
Gradually, the encroaching black mist enveloped a nearby hill, which had a large tree on it.
"Crackle!" The moment the mist touched the tree, it was as if boiling oil had been poured on it, the tree immediately shriveled and wilted!
Before the black mist completely consumed it, Ryan saw the entire tree droop and die!
"What a powerful toxin!" Shirley and Lina exclaimed in unison, unable to comprehend the origin of the black mist.
