It's not that the creatures' base had incredibly powerful living beings or that they had any extremely potent weapons in their hands. After all, Zhou Tian's strength was there, and even if those living beings were strong, they couldn't possibly be much stronger, unless this world truly had a single existence that unified almost all living beings. Otherwise, even if this land did nurture strong individuals, their strength wouldn't significantly surpass Zhou Tian.
And considering Zhou Tian's strength, even if there truly were enemies stronger than him in this world, he wouldn't encounter them just by casually approaching any creature's base. So, from any angle, when Zhou Tian wanted to enter that base, there shouldn't have been any enemies stronger than Zhou Tian.
Thus, given Zhou Tian's strength, as long as he had the mind to do so, originally, when he intended to enter that base, it should have been impossible for any creature to have the ability to stop him.
