The two brothers came for the Divine Mountain, with clear objectives and a straightforward approach, doing whatever was convenient.
There was no way to linger like in Dazhi City; according to Yin Xu, they were already being watched by several parties and could be attacked at any time. How could they not act quickly?
As for whether their intentions would be exposed, Shi Chun wasn't afraid at all. He just wanted to use his right eye to survey the situation inside first, see if he could find the 'Reversing Soul Tree', and explore the coverage of the ancient formation. Outsiders wouldn't see anything significant.
As Shi Chun had just told Wu Jinliang, it was unclear what Lou Xiu was really up to. The more suspicious he appeared now, the more likely they could keep him stable.
Opening their eyes to the Divine Mountain? Lou Xiu was stunned, not expecting Wu Jinliang to make such a request.
