Zhou Tian knew very well the true strength of the Paradise world, as in the past he had already experienced an invasion of the Paradise world, but back then, Zhou Tian's invasion resulted in complete failure. Even though his strength at that time was not as formidable as it is now, the truth is that Zhou Tian made a full-strength assault and still had to retreat from the Paradise world.
Although Zhou Tian's defeat back then was not entirely due to the resistance of the Paradise world, one cannot deny the fact that if the Paradise world really had no strength at all, Zhou Tian could have annexed it with the tactics he employed afterward, and the subsequent events would not have occurred.
