Chapter 570: Chapter 142: The Tenth Hall

Fang Han didn't believe in any oath; he only believed in reality. So, he intended to use the Avici Demon Qi to control the Black Abyss King's Dark Primordial Spirit. If Black Abyss King dared to betray him, he would be killed instantly. Previously, when Fang Han subdued the Great Asura Demoness, he had also used a "Forgetfulness Talisman".

However, now Black Abyss King's power far exceeded the Demoness', so the Forgetfulness Talisman could not control him. Only the talisman condensed from Avici Demon Qi could subdue this person.

Seeing that the Black Abyss King allowed the Avici Demon Qi to enter his Dark Primordial Spirit without any resistance, Fang Han secretly nodded in his heart. If this man had resisted, he would have killed him without hesitation to prevent any future problem. Eliminating a potential threat.
