Since Zhou Tian believed there were no problems with his plan, he simply executed his plan to achieve his goals.
Thus, under Zhou Tian's control, when he used the power of the Abyss World to deal with the Divine Kings, he indeed caused quite a bit of trouble for them.
Using the power of the Abyss World to kill Divine Kings is not an impossible feat. After all, no matter how strong the Divine Kings are, they can't be stronger than an entire world. So, if a world truly decides to take someone on, using its massive power system to crush one or two Divine Kings is definitely possible.
However, although theoretically, it shouldn't be difficult for the Abyss World to deal with the Divine Kings, the current situation is somewhat special. Therefore, what the Abyss World originally had the ability to accomplish may be beyond its capabilities at present.
