"The number of dead cultivators is going up." the System said and Jin started to scratch his head. He knew that there was nothing he could do unless he decided to put up an anti magic barrier to protect the cultivators from being teleported into the rat's kill zone.
Thankfully, the cultivators did not think that way and assumed that it was part of the dungeon instance's design. The Pandarens who were killed mercilessly by the Demon Rats could only assume that they should not be in those magic circles and decided to write it in the forums.
With the Royal Zodiac Heads leaving the dungeon instance and returning back to their respective workplace (with the exception of Se Chang Chang), there were no strong supporters to assist the rest of the Pandarens other than themselves. So by writing in the forums, people who were defeated and resting in the Luxury Recovery Instance knew what to expect when they went for their second round.
