As the Heavenly Thunder kept falling, while Zhou Tian was injured by the Heavenly Thunder, the Negative Karma Force on him was constantly decreasing. Moreover, when the Heavenly Thunder eliminated Zhou Tian's Negative Karma Force, the power of the Heavenly Thunder that kept falling on Zhou Tian began to weaken at that time.
Whether the decrease in Negative Karma Force is good or bad for Zhou Tian is unknown, but at least at that moment, Zhou Tian's action would not change for any reason. Since he decided to let the Heavenly Thunder continue to fall on him, Zhou Tian wouldn't change because of the weakening power of the Heavenly Thunder.
In contrast, when the Negative Karma Force on Zhou Tian became less and less, although Zhou Tian's injuries started to worsen, Zhou Tian also felt that his Diligence was indeed bearing certain results.
