It turned out that the sect masters and respected elders of several immortal sects had been killed.
Moreover, the way they died was rather strange.
It did not look like the cultivation techniques of those immortal sects, but more like some vicious cultivation techniques of the demons.
Therefore, before those people from the immortal sects and sects could investigate clearly, they were certain that this matter was done by the demons.
But they also felt that their sect's sect master and elders couldn't die at the hands of ordinary demons. It had to be Demon Monarch Ao.
They had originally wanted to confront Demon Monarch Ao.
Unexpectedly, Demon Monarch Ao was suddenly killed.
In that case, the new Demon Lord that appeared in the demon race would naturally become the murderer that their immortal sects and sects had determined.
