The altitude was inaccurate to begin with, and now after crawling sideways for an unknown amount of time, a mere two or three zhang of error could result in missing the correct spot by a whisker.
"I think we've gone past it, Sister Guan," Kong Lanting also saw the predicament, "Why don't we climb up and look for it?"
Guan Qianyan hesitated, "No, we're most likely already beneath the Enforcement Hall now, climbing up would just get us caught... and speak softer."
"...."
