They left the area near the abandoned and old mansion—the ex-Dungeon—to complete their further goals.
For one, Mark wanted to maximize that sense of fullness. He wanted to kill more. He also had other plans.
For the first part, they just had to kill a bunch of pigs, and he could kill as many as he wanted in a nearby slaughterhouse.
Convincing the Pig Butcher to give tens of pigs away for slaughter didn't take much effort. Yuri was ready to give him money, which made things much easier for Mark.
They made the Pig Butcher leave the slaughterhouse for half an hour, and Mark—the easily identifiable Demon—entered the countryside building silently, along with Dona.
They wore yellow raincoats to avoid the blood getting on them, and then they began a slaughter. Funnily enough, Mark used the nearly 2-meter-long corpse of the snake as a belt around him—he didn't want to get it burned.
