The search for the whereabouts of Ling Han and the Empress naturally ended in failure again.
And from this, Ling Han found out that at least a Dividing Soul Tier elite was still not strong enough to discover the existence of the Black Tower, and when he thought further about it, the Heavenly Emperor of Thunder and Fire, too, did not show any reaction about the Black Tower.

If he encountered an Ascending Origin Tier elite, he would have to be careful… In any case, Celestial Kings were definitely capable of discovering the existence of the Black Tower. This was something that Small Tower had reminded him about over and over again.
Han Hongfei was very furious. He, a powerful Yang Soul grand elder, had made a move, and he was actually going to return empty-handed?
