The Heart of Fear, that once was the Underworld Venerate's signature unique skill, an ability so powerful that it seemed to defy nature. Except for those equal in strength to him, no matter how high someone's cultivation was, one glance from the Underworld Venerate would instill a fear in them in an instant—a true, intimate fear that stemmed from the very depths of one's heart, irresistible and indefensible. Those who were affected would most likely die painfully from the fear within their hearts if nothing unexpected happened. Due to the existence of the Heart of Fear, during the great war, no one dared to lay a hand on the Underworld Venerate except for the Pioneer. Of course, Dao Zhun was an exception to this.
