The Ruins Beasts feed on fear.
Thus, their cruelty and bloodthirstiness are beyond imagination.
They will torture any creature they capture, gnawing on their flesh bit by bit right before their eyes.
Any creature will generate intense fear as they watch themselves being consumed bit by bit.
And this is exactly what the Ruins Beasts need; the more intense the fear, the more excited they become, until they've drained the last drop of blood from their prey.
This is the Ruins Beast!
However, for the Ruins Beasts to grow and advance, they must consume enough fear.
Yet, in the region of Cyan Mist Hall, not even a few Golden Core Cultivators have fallen, so how could a fourth or even fifth-level Ruins Beast emerge?!
Clearly, it was not born in that area.
This is the reason that caught the Empress's attention.
If Yan Yu hadn't been in that area... it's feared that everyone in Cyan Mist Hall, all the cultivators, would have perished within.
Is this just a coincidence?!
