Causality.
This is a term far more mystical than creation, all spirits, all forms, and so on.
Chen Mu's understanding of causality is shallow, or rather, his affinity with it is poor. There is a fundamental reason for this: to explore causality, he cannot avoid the system panel itself!
Tracing his past, in that small Prefecture City, he unexpectedly met Xu Hongyu, gained her appreciation, this was the effect. Tracing the cause, it was because he relied on the system panel to master a blade technique, which led to the subsequent effect.
Similarly,
The first opponent he encountered, He Mingxuan of the He Family, saw him as an enemy because he joined Xu Hongyu's ranks, attempting to kill him numerous times, but ultimately perishing at Chen Mu's hands.
The most significant reason for this outcome was his use of the system panel to rapidly and significantly increase his strength, acquiring means to eliminate threats.
