Villains in the Cave

You must have heard that Cuirinia is collecting souls. She has also enlisted many monsters to do her bidding which are mostly denizens of the dark.
And the Miasma Cave near the Tor Fortress is occupied by ones that are particularly malicious. They are called the Kezans which used to be ordinary Brokens but became incredibly powerful after submitting to the dark force of Nothernland. Now we find it very difficult to deal with them.
It was Cuirinia who made them stronger so the Kezans now assist in collecting the souls.
And they took our Spirit Bottle, which we use to keep the souls of the dead!
We did chase them, but we need your help now.

The <HFFFA7272>Miasma Cave<HFFFFFFFF> is to the northeast of the Tor Fortress. Please help us to find the Spirit Bottle by eliminating <HFFFA7272>30 Kezan S条目<HFFFFFFFF> on the <HFFFA7272>Miasma Cave 2nd Floor<HFFFFFFFF>. I will be counting on you!

Please. We must have it back before it falls into the hands of the Kezan Commander. Please help us to find the Spirit Bottle by eliminating <HFFFA7272>30 Kezan S条目<HFFFFFFFF> on the <HFFFA7272>Miasma Cave 2nd Floor<HFFFFFFFF> located to the northeast of the Tor Fortress.

Whew. What a shame. We were a tad late. It seems to have left the hands of the Kezan S条目 already.
Hmm…… What do we do now? I don't know. I haven't got a clue. What should we do?
