It would be a bit troublesome for him to suddenly target an Omniscient Sky God like this, especially since he couldn't use his Spacetime Soul Nature to the full degree he wanted, or his Chaos Qi.

However, because she held so much hatred for him, it had allowed him to pry into her mind and read some of her secrets. If she hadn't been so enraged by him, this would have never been possible, at least not so easily, even with his improvements.
However, at the moment, Ryu's comprehension of Temperament and personality had elevated his Dao to an unprecedented level.
