Hi everyone I been looking for this quest for long time ago and by making some research I finally finish it. and now I'm glad to share it with all of you
*Note* You must finish the Eden quest:Chef is Wanted (second part of Asmode quest) or made team with somebody who has the Evil Key

First step: Go to hank using the tomb entrance then follow the Loster 'till you find Exit Ghost


Second step: Talk with Hank who will ask you to defeat three different kind of mobs in the Gulp Room


Third step: You have to go out of the Gulp Room, remake the team and re-enter again so you can start killing the mobs
*Note* The items are being give randomly so you may do the third step few times
Elite Fire Mummy can be find by clicking the statues in this area

Dark Elite can be find in this area

And Bloody Demon can be find around this area


Forth step: After you got all the samples bring them back to Hank then he'll ask you to defeat Demon Kidace so you have to go to this statue to get inside with it


Fifth step: After you killed Demon Kidace return to Hank and report and receive the rewards
