My World Blue Star Forecast

This is a novel that I wrote casually when I was bored at school. Now I hang it on Bibi and share it with you. What I said in front may be a little watery, and what looks good is behind. 
There is no personal heroism in this book. 
It is a comprehensive novel made by countless people. 
Is that there are two races on the same road, Human beings and the undead, human beings are intelligent, but very weak, good at using red stone technology, with numerous thoughts and languages, but human beings cannot operate magic. After the third season, some undead and human mixed race people can use magic. After the fourth season, human beings also began to learn magic in many levels.
