The Yaoguai Stone is in the Yanggok cave all the way in the end in Daseba Temple, since we cannot enter it a GM probably has to go in there and destroy it after that it will never spawn in there again.
We need you to go to that map and try to kill it for us You can do it at any faction we dont mind since we can kill it every 3 hours after it has been killed once Or try to fix the abyss stage 2-3-4 and so on Thank you
