The World at The Bottom of The Chasm

Su Wan finally remembered where she had seen the runes that were on the brick! It was the runes of the ancient Sunken City! 

She had seen these runes on the internet while searching for things about the Sunken City. 

Historians had studied these ruins. Sunken City existed a long time ago. All buildings at that time used runes. 

The ancient and mysterious runes combined with the buildings to build the grand project of that era! 

"So, this place beneath the territory is related to the Sunken City?" asked the White Dragon Saint. 

Su Wan didn't have a definite answer for this matter. "Not necessarily," she said. "Maybe one of the bricks from the Sunken City had fallen into the dark river beneath our territory…" 

Su Wan stooped. Xu Yuan, who was beside her, pointed out the flaw in her explanation.
