It's okay, but the is a lot of filler. The two things that the author is doing at this point of the story that frustrate me most is that the system is meant to be an afk type system but the main character doesn't use it even when he could and how much the main character ignores training mental power. There are several periods of time where it would be very efficient to train mental power like choosing between an entire point of mental power or gettong 0.01% progress of his body refining and he still chooses to refine his body. Made even more annoying by past events in which mental power is what helps him breakthrough bottlenecks and despite reaching a bottleneck with his qi he still doesn't even attempt training mental power despite the bottleneck almost explicitly having to do with emotions which would likely be helped by train mental power.
