"What's wrong?" Fei Ying asked carefully.
Gu Qingshan's expression was grim. It seemed he had run into a problem unlike any he had ever faced.
"The real Fundamental World—or rather, the world unlike all the Parallel Worlds—is the one reached through the door at the bottom of the Eternal Abyss," Gu Qingshan said.
