Tianyuan Pastoral Record

The world is divided into "outer world" and "inner world". The outer world is a "pastoral" with thin spiritual energy but peaceful times. Several ancient aristocratic families maintain a false peace and order and practice farming, studying and inheriting the family. The inner world is the real world of immortality called "Tianyuan", where the spiritual energy is violent and thousands of races are fighting. It is a real place where the weak can eat the strong.
