Bao's analysis indicates that to open the gate at the bottom of the courtyard, you must first locate three "keys" to activate the three mechanisms in front of it.

I'm sure the treasure's behind this gate! But how do we get it open...

I get it now! The keys we picked up earlier are used just for this!

The treasure's right within reach! Let's activate the mechanism!
