It was an extremely clear and bright cry of an infant.
What was eerie was that it didn't come from any particular direction, nor did it sound just once.
Instead, it rose from all around, multiplying upon itself from the void.
It was as if thousands of infants were suspended in the air, crying all at once. The perfectly synchronized wails split into several parts, echoing in rounds like a symphony, exuding a strange sense of the sacred.
The moment Lin Yiyi heard that sound, she felt a strong buzzing in her mind, and a strange cool sensation drilled into her head, shooting straight down to her tailbone.
Suddenly, several lines of prompt flashed before her eyes:
[You have listened to the sacred sound, and your erosion level has been reset to zero.]
[You have received a new mark "Low-level Influence: Infinite Overlapping Echoes".]
[If not removed in time, you will fall into a random nightmare with the keyword "Mirror" in seven days (Difficulty: Hard).]
