Previously, in green ghost desert, Fang Yuan had used great thief ghost hand to steal rank eight Immortal Gu Soul Beast Token.
Great thief ghost hand was only a rank seven move, and its core was rank seven great thief Immortal Gu. But with the help of the killer move yama, its power rose to the point where it could steal a rank eight Immortal Gu from the legendary immemorial soul beast Qing Chou's body.
Back then, great thief ghost hand's effective range was extremely short, which required Fang Yuan to get near the target.
After returning, Fang Yuan modified yama, adding in great thief ghost hand to form the completely new emperor yama killer move. Right now, great thief ghost hand not only had a long range of effectiveness, it also had the ability to conceal itself.
It was not strange for Meng Tu to be struck by it, instead it would be unusual if he was not struck.
