I got the Bomb Incense and went to the Garlaige Citadel to click??? But there was no response. I tried partitioning, and I couldn't.It's no use doing the task again. Does anyone know what's going on?

Not sure what you mean when you say you tried partitioning, but I'd triple check you have the key item to start with then triple check you're at the right ??? spot. Per the Nas wiki:

Once you enter Garlaige Citadel, head to the southeast corner near the Banishing Gate #1.
On Nasomi you will only receive a message that says "You sense a presence from in the ceiling." at every ???. If you do not receive this message, you missed something.
Look around for a ??? at (I-9).
Head west a bit and look around at (H-9) for another ???.
Go through the first Banishing Gate and follow the map down to (F-9). The ??? to the west of the intersection is the one you want.
Go across the hall to the east for another ??? at (F-9)/(G-9).
Go back the way you came, towards the Banishing Gate and examine the ??? at (G-8)/(G-9).
Head to the north of this area for another ??? at (G-7).
Head east to the ??? at (I-6) for the fight.
