(The story is set in a time when the development of the world of cultivating immortals was not yet complete, so there are many private settings. The author is not well educated, so please forgive me for his lack of writing. Please point out common sense errors, hehe)
By chance, some mortals mastered the use of spiritual energy and started the process of cultivating immortals. However, for some unknown reason, heaven and earth took away most of the spiritual energy and replaced it with useless pure energy. This gave birth to the four major sects and led to more and more people cultivating immortals.
Everyone has their own tasks. Some people seem to be promoters, but in fact they are chess pieces responsible for execution. Don't think too much, only take action to find the answer.
Intention: Heaven and earth are unkind and regard all things as stupid dogs.
