Everyone knows the Black Demon truly exists and is among the crowd, yet no one can pinpoint him.
Emperor King Song's face was gloomy, Yin Yang Great Emperor's brows furrowed tightly, Dugu Great Emperor's gaze was venomous, while Chu Family Great Emperor was somewhat impatient.
These four families hold the greatest hatred toward the Black Demon, because the Imperial Son and Emperor's Daughter they carefully nurtured were slain by the Black Demon.
Yet at this time, no method could uncover the Black Demon, causing them some headache.
Of course, the best method would be to kill everyone coming out of the Heavenly Medicine Blessed Land, but that's unrealistic.
"The Black Demon only broke through to the Saint Realm after entering the Heavenly Medicine Blessed Land, even attracting the Saintly Tribulation Thunder. I think everyone who broke through to Saint Realm after entering the Blessed Land should be investigated."
