[Third Person POV],
Seeing the bloody appearance of the rat queen's body, Ace had no expression on his face, nor did his body react in any way that betrayed his thoughts as he moved closer to the rat queen after carefully placing the still sleeping blue on the ground.
When he got close to the rat queen's body, Ace bent down as he reached out to start harvesting the crystal core of the rat queen.
His actions were fast and fluid, as he did not hesitate in what he was doing.
He also did not need to hesitate since it was already confirmed that the rat queen was dead since the primordial chronicle would not have sent a notification that he had received its primordial records except that monsters can now revive after death, so Ace did not hesitate in whatever he was doing.
Apart from his assurance in the primordial chronicle, Andrew Dawn was also there, so there was no need to be cautious about the rat queen or any other monster that could be around.
