The wailing sound was so mournful that it inevitably evoked a sense of desolation in He Ao's heart.
He Ao frowned, his gaze disappearing into the pitch-black night.
He had miscalculated slightly; the visibility in the darkness of the ruins was even lower than he had imagined.
Looking down from the rooftop, he couldn't see the ground at all, only a deep, pitch-dark abyss.
And that mournful cry had come from the depths of this abyss.
Vaguely, He Ao could see a huge, slender creature, black as ink, 'swimming' through the 'abyss' between the buildings below his feet.
At this moment, beneath the tall buildings, within the veil of night, those inky depths unseen below were like the unfathomable deep sea, and the giant creature was wandering in this 'deep sea.'
And the night was the 'water' it lived in.
