One could imagine how difficult it still was to affect that type of energy, even after his cultivation level of the rules had been greatly enhanced. Without the experience of entering this world, with Zhou Tian's original cultivation level of the rules, it would likely have been utterly impossible to influence that energy.
Undoubtedly, given the destructive power of that energy at the time, if Zhou Tian had not imposed any restrictions, his physical body would have been destroyed in a short period of time by its capabilities. Under the effect of that ability, even Zhou Tian's immortal body might not have been able to preserve his life.
Therefore, the benefits brought about by the experience in this world were truly significant for Zhou Tian. It could even be said that it was precisely because of that experience that Zhou Tian had a glimmer of hope.
