Yang Zhen's enlightenment was not feigned; from a young age, his teachers had instilled in him the habit of regularly planning his life. The Hongluan Spiritual Girl's question about what he wanted had rendered him speechless.
All along, Yang Zhen had simply gone with the flow, not resisting or going against the will of the heavens, doing whatever he pleased and acting freely.
After meeting the cheat cat, the cat constantly incited Yang Zhen to stir up trouble. Even without the cat's incitement, Yang Zhen's style of doing things caused chaos wherever he went. However, being with the cheat cat provided Yang Zhen with a sense of liberating satisfaction.
Doing whatever he wanted to do, stirring up things whenever he wanted to was Yang Zhen's life plan.
But why did he choose to live this way?
Yang Zhen fell into endless self-questioning until the moment he and the three others, including the cat, entered the Genjin True Pattern, and then he had an epiphany.
