Although Zhou Tian did not actually die at the hands of those demigods, he had taken note of their actions. Without the power to seek retribution, Zhou Tian could act as if nothing had happened, but once he was capable of retaliating, he did not mind teaching those demigods a lesson.
To seek vengeance, if Zhou Tian did not take revenge on his enemies when he had the capacity, he would probably feel that his thoughts were not flowing properly! After all, from any perspective, Zhou Tian's strength was firmly above those demigods by more than just a notch. With his current strength, combined with the help from his subordinate bosses, it was almost certain to confront those demigods who had troubled him before. Thus, since there was no danger, Zhou Tian would certainly take revenge on his former enemies.
