章 260: Invincible Black Demon Falls, Earth Heavenly Abyss!

Outside the Rose Heavenly Domain, Mu Xuan looked at the panic on Black Demon Invincible's face and smiled. Who told him that he would only extract a little power?!

After advancing to the quasi-ancestor level, the absorption efficiency of the Rose Heavenly Domain directly doubled, and the duration doubled. This time, the Black Demon Invincible would at least have its strength absorbed by two levels. If its luck was bad, it might even drop to… quasi-ancestor level 5!

As expected, fifteen minutes later, Black Demon Invincible's cultivation level fell to quasi-ancestor level 5… His eyes were filled with shock. This strange skill had actually become so much stronger. There was something wrong!

At this moment, Black Demon Invincible realized that the power suppressing him had finally disappeared. Resentment appeared in his eyes, and he was about to use a spatial skill to directly wake the Black Hole Giant up!
