493. What is a monster?

Lin Wu pursed her lips. "The people who went to Thirteen Ridges that year were from the Chi surname clan. The two we just saw, are they really descendants of the Chi Family?"

"Indeed."

"Then what has happened in the Underground City over these years? It seems that the original five clans have been living in the Underground City all along, continuing to guard it. But according to what those two said earlier, it seems there was trouble within the Chi Family, and that's why they left the Underground City for the outside world. What could have happened?"

"Unclear."

Mou Chuan stated calmly, "The formation of the Underground City involved the participation of the former seventh Ridge Master of Thirteen Ridges, which is why Thirteen Ridges paid extra attention to it. Later, the seventh Ridge Master vanished without a trace, and the Underground City was peaceful. Thirteen Ridges no longer paid it any heed. What has happened since, we are even less certain."
