Well guys, I noticed that while making the story logical and not overly simplified, it might actually take Qian Renxue too long to reach the Higher Dimension. She is currently a 4th-dimensional being, though she can be considered a half-step into the 5th dimension because her level is that of a Quasi God King.
To address this, I introduced the concept of the Will of the Universe — essentially the will of the author of the Douluo Multiverse — to accelerate her progress without breaking the flow of the story.
More importantly, after much consideration, I have decided not to expand this story into the multiverse, as that would unnecessarily stretch the narrative.
This is the final arc, there will be another arc but it will be a kind of after story. Here's a hint: it will take place in a different era.
Any other doubts or questions, feel free to ask me.
