On the contrary to Zhou Tian and his companions' situation, the strength from the previous Epochs did not have such obvious weaknesses.
Although cultivation was difficult, once living beings in the power system of the past Epochs reached Domain Level One, their reliance on the world began to wane. Up to the present, beings like Pan Shi, even if they left the Main Plane, could still become powerful entities.
Even if World Consciousness wanted to reclaim the strength of existences like Pan Shi, it simply wouldn't be possible. From this aspect alone, Zhou Tian's Monster power system was indeed considerably inferior to the power systems of the previous Epochs.
Zhou Tian and his opponents' strengths had almost no comparability; if not for his possession of the Human Emperor's immortal body, he wouldn't even need to mention the Deities—Pan Shi also had the ability to kill him at any moment.
