A What?

"Did Asenath implant a seed of her Original Law into Freya when she freed her?" Yan Zaizen actually felt a tinge of pity towards the death of Freya. There was no guilt, but just a somber sense of pity for her unfortunate fate.

In fact, Yan Zaizen had been partially at fault if that was the case. However, what could he do and why would he do anything about it? Freya made her choice when she struck to kill; she made her choice when she allied with an untrustworthy ally, so he, who believed the value of consequences in decisions, felt no guilt.

As for the Oneuli Empire's Emperor, Yan Zaizen felt somewhat interested in that backstory. As someone who gleaned an understanding in the Dreaming Devil Law, it's not possible to infect someone who've reached a certain cultivation base, unless they were at a moment of weakness or lapse of attention.

For example: Freya.
