Looking at the location of that large sandbag, it seems to be the place where the Quicksand Priest was before.
Du You had Xiaozi land, climbed down from her back, then released the Cursed Crow King. This fellow had died several times already, yet he is still fearless, just like before.
"Hmm, it still moves, it hasn't died, has it? I've heard that a Quicksand Priest isn't particularly powerful. Their main ability lies in their blessings. If a Quicksand Priest is with a group of Quicksand Soldiers, the threat can be quite substantial. But as it stands now, this one is isolated, which means there isn't a problem," Du You thought, referring to his previous research, and did not seem overly worried.
The large sandbag was revolving incessantly, and the hemisphere-shaped bag slowly slipped downwards, gradually shedding off.
The Quicksand Priest, with his haggard and ugly face, appeared before Du You.
