Strictly speaking, in terms of technology alone, the "super engine" designed and built by the Creation Goddess could never compare with the technological prowess behind Raven 12345. Even so, Raven 12345 still needed to rely on the former's design at this point. That was because, for a long time, she had been faced with an insurmountable barrier: she could not interfere with the Dream Plane, nor could she even observe that fragile companion universe. For years, she had only been able to observe the condition of the Wall of Reality from the Outer World and learn about the Dream Plane's internal structure through various indirect means. As she had said, when it came to understanding the interior of the Dream Plane, she knew even less than Hao Ren did.
So she had no way to begin dealing with the problem of the Wall of Reality.
However, the Creation Engine had now become a massive breakthrough. On the other side of the Wall of Reality, the Goddess of the Dream Plane had completed her observations and plans for the entire Dream Plane universe and designed this magnificent artifact that could directly operate on the Wall of Reality. Although her design had many crude flaws, it was still enough to make up for Raven 12345's inability to handle the matter. If the engine could truly function as designed, most of the Dream Plane's problems could genuinely be solved with ease.
Raven 12345 put it this way: "I've been observing things from this side of the wall for all these years, while she hasn't been idle on the other side either. Although I've never met her, we've actually been working toward the same goal at the same time: restoring the condition of the two universes. This is fate at work. All those years
