No matter what kind of modifications Han Dong's right arm went through afterwards, its essence is still the "Ghoul Arm".
When coming into contact with ordinary ghouls, even if Han Dong had just killed one, there is no resonance or homologous reaction.
However, when he set foot in the Ghoul Nest, his right arm trembled slightly due to the resonance.
This indirectly suggests that underneath lies a true ghoul, or an entity that can establish a connection with ghouls... the level of danger is self-evident.
"Disguise Strengthening"
Through subjective control, Han Dong enhances the effect of the Faceless Skull's disguise on his right arm, thus easing the resonance... to avoid being targeted by the entity below.
If the 'King' below leads a swarm of ghouls, even formal knights would be drawn into a bitter struggle... even possibly being swallowed by the sea of corpses.
"What lies below is certainly not simple... It is surely much stronger than [Barber Charlie]."
