What Nangong Wuyue said aroused Hao Ren's curiosity.
"A forbidden territory in the deep sea?" He stared at Nangong Wuyue. "I've heard from Vivian that no one has ever found the location of the City of Sirens. Could this be the forbidden territory?"
"I suppose," said Nangong Wuyue. "Maybe there's some special way to get in there. The deep sea is a mysterious place and very little's been explored by humans. Perhaps, normal sirens could dive in there. But, mom has never mentioned about her hometown. It was like she didn't want me to go there. I don't know why."
"The possibility of mom being there is low." Nangong Sanba shook his head. "If she's there, then why hasn't she come to find us? She's gone to the surface once, she could do it again if she wanted to."
"I'm going to carry on the search even if I fail to find her in the end," Nangong Wuyue said softly. "For years I've been looking for her and it's become a part of my life."
