I'm not going to lie to you, it's not my kind of reading and it gets pretty boring, 4 chapters and there's nothing interesting, it just trains and tells information about everything, and that's it, if you want you can read it.
The first chapters are to attract people, you don't throw them information of all the energies and systems that fill the chapters, as well as boring conversations, that's my point of view, you can keep writing as you want.
