Ye Futian looked below. Naturally, he knew that Fang Ru was right that the will of Ziwei the Great was hidden amongst the celestial stars. He could indeed borrow them in battle, but his Plane was will a little low after all. He was only seventh-level Renhuang Plane, so his powers were limited even after borrowing from the celestial stars, let alone in comparison with the actual Great Emperor.
In fact, he didn't even manage to release 30 percent of the celestial powers. Otherwise, even if Fang Ru were only one step away from becoming Great Emperor, he would still be obliterated.
So what if he was as powerful as one could be short of being a Great Emperor? The Will of the Great Emperor was carved into the celestial stars. The explosive power of its attack was equivalent to a portion of the power of the Great Emperor. It was just that Ye Futian couldn't unleash it fully.
