Review Detail of Jetstorm in Let the Power of Lightning Strike

I'm a neewbe at writing so 4 stars is all I dare give myself...for now. But you shall all tremble before the might of Jetstorm-sama before long. I believe my writing quality to be quite readable. But can't get the stability yet so...yeah. I only wrote 3 chaps not much development above the basics. I haven't introduced the world properly because its the Earth 70% water and 30% land. Though its post apocalypse so should be changes. Which will be introduced when Adam leaves the island. For character design I can't say I'm the best at it but I think I'll work. Basically I'm writing a cultivation novel in a post apocalyptic theme on Earth. I need helpful comments. Any suggestions given should be feasible and in line with the story.
