Just as Ding Feichen said.
In this world, not only do poisons that can control people exist—they're everywhere.
Most Demon Sects all have this kind of poison to control their disciples. Otherwise, do you really think those who join a family's Demon Sect care about things like master-disciple loyalty?
However.
Ye Liuyun disdained to use such things.
Whether Ding Feichen would betray him or not, to Ye Liuyun, it was nothing but an insignificant matter.
It was just a casual move, nothing more.
If he's useful, keep him; if he's not, kill him right away. The world can deceive you in every way, but only your own strength won't.
No matter how many people you nurture or how widespread your influence gets,
if you lack true power, it's all just empty talk.
In the end, Ye Liuyun still let Ding Feichen go, and even gave him a token—the Embroidered Uniform Guard's Southern Governor token. In a sense, this also represented Ye Liuyun's identity.
