In the void and within Northern Wilderness Hill, silence fell as the Holy Heavenly Demon Emperor's words faded. The Heavenly Demon Emperors also stopped attacking, watching the Undying Lord and the others with mocking expressions.
The Undying Lord and the others naturally looked grim. The Extraterritorial Evil Clan occupied half the Great Thousand World's territory—the Demon Domain—and had conquered countless Lower Planes. They had more than enough people to conduct such experiments...
At that moment, the spiritual radiance surrounding the dozens of figures who had pierced the Great Thousand Demon-Transforming Array's membrane dispersed, revealing their forms.
They looked no different from the humans of the Great Thousand World. The only distinction was the sinister eye in each of their palms, slowly opening.
"Tomb Guardians, heed my command! Slay the invaders!"
The Undying Lord looked at those dozens of sinister figures and discovered that the strongest among these Evil Spirit Clan experts had already reached the middle stage of Saint Grade. He immediately issued a low, stern command.
After the Undying Lord's voice resounded through Northern Wilderness Hill, a black-robed middle-aged man, his body surging with a powerful aura, led dozens of figures from the Black Plaza. In an instant, they appeared before the dozens of Evil Spirit Clan members.
"The blood of the Great Thousand World's living beings flows through your veins as well. Do not help a tyrant perpetrate his atrocities!"
The black-robed middle-aged man swept his piercing gaze toward the leader of this group from the Evil Spirit Clan, a gray-haired man.
"The blood of the Great Thousand World?"
Hearing the black-robed middle-aged man's words, the gray-haired man smiled faintly and sneered, "When those of us with the Great Thousand World's blood were penned up like pigs and dogs, where were you people of the Great Thousand World?"
