The plot in the early stage is interesting, and even the non-official sequels have a CP feel to them. In the later stage, I subscribed because I watched them all, and in the ending, I ordered them all because I can only rate them if I subscribe them all.
The logic is not self-consistent. There is no system in the original settings in the book, so how do the villains know about the system? The protagonist is not called an ancient person even if he wears it... Either the meaning is not complete or the blank space is appropriate, but I feel that many local things are unclear and incomplete.
But the introduction is very attractive, and the early stage is very interesting because the author seems to be very good at writing cp sense.
