Something came to me while reading this chapter..... Nothing in the in TDG canon rules is stopping you from making crossover worlds in this fic. For instance there could be a World where the laws make Highschool DXD or Fate Stay Night possible. Honestly the sky is the limit. Got bored for a bit, have Nie Lie troll the Naruto world for a bit. ETC. Your imagination is the limit.
Unless you make a fastpaced novel all type of novels are long, some more than others. You could make an avatar fanfic since in avatar you only have to train there's no concept of resources for cultivation or anything like that. I didn't understand your plans for the remaining of this novel, care to explain more here?
Here is an idea, just have him stay in tiny world. The only reason that I can think of for going to the heavenly fate realm is to get higher realm heavenly energy. His private world has heavenly energy. Just add life to that realm aka crops, plants, soil, bottled air, light stones and other things needed for life to grow. He and his girls could just stay there to cultivate, become dam near immortal and rule tiny world. The Sage Emperor can't enter Tiny world so they can just stay there for the next several hundred years until they have a large family, or army, all stronger than him. Then and only then, if he must, go crush the emperor and his 9 deity rank beasts as easy as taking a walk in the park. And then return to tiny world, after taking away the keys to the barrier. He could rule all of the other worlds and realms from there never needing to worry about being attacked.
