I am uncertain how to rate this novel.
On one hand it has quite a few interesting characters, a few interesting concepts and is written in a very entertaining way.
On the other hand there are quite a few logical errors, which are necessary for the plot, but could potentially lead to problems and inconsistencies later on.
20 Chapters are not enough to judge this book.
In general this is a novel in which the transmigrator has reach a very high level, but is totally unaware of this fact because he lacks the common sense and basic understanding of the Cultivation world.
The MC is so OP that his 3 common animal pets are already the strongest around, but they do not know it either because they have no inheritance or bloodline of any kind. It is basically a feed back loop of 4 fools, strengthening each others misconceptions.
All in all, a fun read with potential, but not enough to justify spending money so far.
