He slipped away!
After releasing those Slaves, Liens stealthily slipped out of the Slave Exchange.
Although he didn't know if these Slaves would have a chance to successfully escape, their escape would definitely cause some chaos.
It should be able to divert some of the Glenbagen Family's attention.
That way, he would be safer when he made his getaway.
After leaving the Exchange, Liens changed out of his blood-stained clothes and removed the Illusion Mask from his face.
Then he "borrowed" a fire-starting tool from a nearby house and burned all of these items.
Although the Illusion Mask was very precious and rare, several times more expensive than everything he owned combined.
He was worried that the Glenbagen Family might leave some magical mark on it, so he could only burn it to prevent it from affecting his escape.
