If Zhou Tian hadn't used that method to once again demonstrate the effect of the Human Emperor's immortal body, based solely on the situation at that moment, even if Zhou Tian wouldn't have died from the opponent's attack, he would likely have already been severely injured by those two strikes. Given the strength of those two living beings, once Zhou Tian was severely injured, even ensuring his own safety would have become a problem, not to mention defeating the opponent.
As a result, in that situation, Zhou Tian was indeed able to leverage the effect of the Human Emperor's immortal body to quickly recover from the injuries inflicted by the opponent's attacks. Now that his injuries had fully healed, everything else became much easier to handle.
