Liang Qu's own "smuggling" undoubtedly bypassed the "washing machine."
This alone shook the vast foundation of the Blood River Realm, hence making everyone feel threatened.
This is not hard to understand.
The Great Ancestor Dali is a Melting Furnace, not a Rainbow Transformation. The Blood River Realm is incomplete, not whole; otherwise, Dali would have long become a Rainbow Transformation, and the Heavenly Fire Sect wouldn't need to keep it for compensation.
Why is the washing machine so important?
Liang Qu thinks it's not just that the Heavenly Fire Sect is worried about shaking its foundational rule.
The Underworld people know they have already died and have been washed of everything—power, memory—innately becoming opposed to the Heavenly Fire Sect, much like Huizhen, who is aware of her situation. Even if she doesn't align with Liang Qu, she is at least opposed to the Heavenly Fire Sect. If more "Huizhen" could be found, they would all be allies.
