As the Blood Fiend Ancestor and others like him descended upon this world, they retained their complete Realm strength, but in actuality, they were still subject to the world's invisible suppression. Before they had adapted to this foreign environment, the true combat power they could exert was indeed somewhat lower.

For a True Immortal Strong like the Blood Fiend Ancestor, these effects were negligible. Even if they could not exert their maximum combat strength, they still stood at the pinnacle of this world.
