The planet Y605 in the interstellar year 560 is divided into Siyuan Sect and Wuxun Sect.
When people are 20 years old, they will undergo their first differentiation (adulthood at the age of 20) and determine the sect for practice. (Not all of them will be differentiated. Successful ones will be taken to professional places for training.) However, these two sects are peaceful on the surface, but they are somewhat discriminatory (referring to enemies who need to be caught by the sect).
Every Siyuan must be matched with a Wuxun.
But is that all?
Intention: double strength
