The story is very entertaining and relaxed. It could be said that it focuses more on how the MC develops more of his abilities and how he uses them to break the common sense of the world in which he finds himself. But you can understand why, the MC thinks outside the box and doesn't focus on increasing his strength with the already established methods. The "how can I improve certain aspects of cultivation" is always present, be it with alchemy, matrices, etc. I especially liked that he is realizing the importance of the energy that everyone uses to cultivate, he understands that it is moldable, it can have different attributes, present in everything. Basically, he's achieving "The Dao Of Profound Energy" hehe.
The harem could be said to be a secondary bonus, it's not that relevant apart from getting girls
(Pokemon), but I really like the interactions he has with his wife and the occasional girl. Especially, the point of view of the girls means that they are not just decorative vases, with this it is understood that they exist and have personality.
I recommend improving the interactions with the other characters, since the novel could become a monologue of the MC. Of course not everyone wants chapters with unimportant dialogue, but at the same time it gives the other characters an authentic flavor. For example, I like the MC's first wife, her inner thoughts of being jealous of her or her acting spoiled is nice.
I'm not an author, so not how hard it is to make those small changes. But you can say that this fan-fic has potential, so the author should take his time and decide if it is feasible to achieve them and not go against what he seeks to convey in this fan-fic.
You can't have the best of both worlds. So I'll see where this fan-fic goes.[img=recommend][img=recommend][img=recommend][img=recommend][img=recommend][img=recommend][img=recommend][img=recommend]
