Xu Jingming nodded solemnly.
For such a heaven-defying bloodline secret art, side effects were perfectly normal.
"The cultivation of the Purple Nightmare Demonic Canon requires Demon Essence Blood. I have already prepared that for you."
Purple Nightmare Master raised his right hand, palm facing upward. "If you hunted devils yourself, you could only obtain Star Radiance Level Demon Essence Blood.
"But you are the inheritor of me, Purple Nightmare Master. Naturally, your Demon Essence Blood must be of the highest caliber."
His five fingers slowly curled inward, and a savage rift suddenly tore open in the void.
In an instant, the entire Secret Realm trembled violently.
Countless bolts of Purple Heaven Divine Lightning burst from the rift, like hundreds of millions of lightning serpents dancing wildly.
Xu Jingming felt every hair on his body stand on end, seized by the terror of facing death itself!
The next moment, a droplet of purplish-red blood slowly emerged from the spatial rift.
The droplet was no larger than a thumb, yet it seemed to bear the weight of an entire world.
Black, purple, and crimson halos flowed across its surface, while countless miniature bolts of lightning could vaguely be seen intertwining and colliding within.
"This is...?" Xu Jingming was deeply shaken.
It was only a drop of essence blood, yet it could cause such a commotion?
"This is a drop of heart essence blood taken from a Thunder Prison Demon I slew in life and preserved until now."
Purple Nightmare Master's lips curved slightly, his voice carrying a hint of reminiscence.
"Thunder Prison Demons possess an Upper Bloodline among the Devil Race. Upon reaching adulthood, they can rival Eternal Gods.
"This one had even reached Master Level. I fought it for several months before barely gaining the upper hand and killing it completely."
