The Nightmare Demon went mad.
The instant A Meng dissipated completely, a roar and a shock wave erupted from its body.
The restraints Su Jiu had placed on it were utterly shattered in that same instant.
The Nightmare Demon turned into a mass of black miasma that gradually spread. Before long, mist that blotted out the sky and sun engulfed their surroundings.
Something seemed to occur to Su Jiu. Her gaze sharpened, and she warned coldly, "Be careful of this mist. Don't let it invade your bodies..."
But Su Jiu's warning came a step too late. In that brief instant, quite a few disciples had already inhaled the mist, and their expressions began to grow dazed.
Su Jiu pressed her lips together and carefully wrapped spiritual qi around her entire body. Naturally, some of the disciples who had heard her warning did the same.
Someone asked in bewilderment, "What exactly is going on?"
"The Nightmare Demon wants to take us down with it."
The Nightmare Demon actually had another name: the Dream Demon. Its greatest strength lay not in its combat prowess, but in the dreams it created.
The nightmares it created were different from ordinary people's dreams. An ordinary dream was only a dream; even if someone died within it, they could still live on. But the dreams it created were lethal weapons. Anyone who died in one would have their soul dissipate completely.
And that was the most terrifying thing about the Nightmare Demon.
However, such powerful Innate Arts were not without restrictions. The restriction was that the Nightmare Demon could only use them after a person fell asleep or their consciousness entered a state of light sleep.
Yang Guo looked at their increasingly dark surroundings, then at her fellow disciples, who were clearly no longer fully lucid.
