Zhou Tian was also aware that beings like Pan Shi possessed a plethora of life-saving capabilities, and if he truly intended to kill Pan Shi, that would be almost an impossible task to accomplish. Yet, at this point in the combat, the fact that Zhou Tian could gain the upper hand over Pan Shi was no easy feat. Now that he had the opportunity to kill Pan Shi, Zhou Tian naturally would not consider giving it up, no matter what.
After all, even if Zhou Tian was capable of defeating Pan Shi now, he had to admit that Pan Shi was different from the opponents he faced in the Main Plane. If not for the World Consciousness's repulsion against him, Pan Shi's threat to Zhou Tian would definitely be much greater than those Deities and the Human Emperor.
