Review Detail of TheGratefulStar in Astral Apostle

Chapter 1-200's story was really good for me, then started the school part which was quite boring (MC can't do astral travel because his ability is having problems). Then after half a year of MC at school, MC can use his abilities again. The second world of MC goes named D19, there is a kingdom named "Great Xia". And yes it is the world of martial arts with cultivation.
