"Yes."
"How far down?"
"About two hundred zhang."
"There should be water."
"There is."
Mo Yuxin stopped.
The passage opened into a huge underground chamber.
And an entire street had been built beneath the city.
Wooden houses stood in rows.
Old shop signs hung from cracked beams.
A stone road ran through the middle.
There were wells.
Bridges.
Shrines.
Even a small square with a dry fountain.
It was an underground town.
Su Yubing stared.
"Bluewave City was built over another city."
Mo Yuxin nodded.
"Or around it."
They walked farther.
The buildings were empty.
No bodies.
No skeletons.
No signs of violence.
Only abandonment.
Mo Yuxin touched the wall of a house.
A faint spiritual imprint remained.
Families had lived here.
Children.
Shopkeepers.
Cultivators.
Fishermen.
Normal people.
Then, one day, they had left.
Or disappeared.
The underground street was silent enough that their footsteps sounded loud.
Su Yubing reached for Mo Yuxin's hand again.
