Nitotipu's so-called secret passageway was actually not a true secret passageway, but an underground pipeline.
Even then, there wasn't a single door that led to this pipeline.
To enter this pipeline, one had to break open the ground on one's own.
Yadasai knew about the existence of the underground pipeline as well; however, it remembered that the pipeline was filled with inscriptions, and the slightest damage would cause a backlash from the inscriptions. One should know, these were inscriptions laid out by ruthless scholars, and once backlash occurred, even if one didn't die, it would definitely make Yadasai suffer greatly.
The section of the pipeline without inscription nexuses, mentioned by Nitotipu, was also unknown to Yadasai until then.
"Follow me, this pipeline isn't near the Void Tower but at the edge of the Shadow Mist Area," Nitotipu said, leading the way.
