The number of visible memory bubbles in the surroundings began to decrease. Yellow fog was starting to appear in the white foggy region, gradually obstructing one's vision. Even with Lao Wang's superb vision, he could only see up to two to three hundred meters ahead of him.
The yellow region was considered a dangerous zone. Other than the memory bubble worlds here, spatial distortions occurred sometimes, resulting in the formation of spatial rifts that opened up to other worlds. The yellow region was way more dangerous than the white region.
Under the yellow fog, the memory bubbles were partly hidden and partly visible. Those bubbles were condensed from the fog, making it harder to tell them apart.
