The Specter King was very cautious. He had studied Tang Wulin's battle recordings closely, so he was rather wary of Tang Wulin's explosive power. He understood that his own immunity to physical attacks did not make him invulnerable to everything. Moreover, energy blasts were still rather effective against him. His biggest advantage was that his spiritual power far exceeded other soul masters of the same rank. He was especially skilled at predicting the enemy's movements and striking first.
