Forcing the vampires to retreat with a shout filled with mighty power wasn't anything extraordinary. After all, it was possible that they might have retreated to give face to Li Yunmu.
But when the terrifying pressure had flitted past Li Yunmu's body, he had felt the pricking sensation akin to needles being inserted into his body one after another. This was an automatic warning of the body when faced with a threat who reached a certain strength!
In other words, the terrifying pressure which exploded forth from the man's body in a split second showed that he possessed enough strength to injure Li Yunmu. And if that wasn't enough, he hadn't even used his full strength!
It was very difficult to imagine that a tyrannical existence like Zhang Xianhu might not have managed to succeeded in the Origin World while someone like Li Yunmu had surpassed him. Otherwise, such a terrifying existence might not have come to find him at that moment.
