Sun Wukong and Shen Lang followed Nangong Po and happened to witness Nangong Po challenging the owner of the cave dwelling on the left side of the waterfall top.
"Shen Lang, you go and challenge the cave dwelling on the other side, leave this one to me, the Great Sage."
Sun Wukong pointed towards the cave dwelling on the right side of the waterfall top.
Nangong Po also saw Sun Wukong and Shen Lang catching up and his expression instantly turned grim.
Just as Sun Wukong thought, Nangong Po originally planned to successfully challenge then have others fail in challenging him, thus securing the cave dwelling for half a year.
But didn't expect Sun Wukong to arrive so quickly!
This completely messed up his plan!
However, once a challenge is issued, it can't be withdrawn unless one concedes defeat, and if defeated, he wouldn't be able to issue another challenge for a month.
