Zane managed to hold back a smirk. "Alright, I'll keep that in mind." After a few more minutes of walking, they arrived at the entrance. "Okay Lucario, let me know if you sense anything." Lucario closed it's eyes, focusing. It didn't sense anything near the cave entrance, so it walked in, keeping it's eyes closed. When expecting an ambush, Lucario kept his eyes closed, using the power of Aura to see where the attacks would come from.
