Chu Nanli was taken aback and looked in the direction of the sound.
That side was blocked by deep bushes, making it difficult to see clearly.
Just as she began to doubt if she had imagined the noise, the suppressed sound of a man's pain echoed in her ears again.
Chu Nanli could now be certain.
There indeed was someone there, and it was possible that they were either injured or suffering from a sudden illness.
Chu Nanli hesitated for a moment about whether to call Yanyan to accompany her.
After thinking it over, she decided against it.
After all, Yanyan was just a frail young girl; if there was any danger, Yanyan could get hurt as well.
Having made up her mind, Chu Nanli took out a silver needle from her sleeve and gripped it between her fingers, slowly making her way into the bushes.
Judging by the volume of the sounds, the person was still some distance away from her.
After walking inside for a while, the view opened up before her.
There was a hot spring.
