While being surrounded completely by blood and corpses, Pati stood up before cleaning the blood cloaking his longsword with a swing, "Eugh...", he groaned feeling that his arm is hurting just from swinging the longsword.
Not only that but the weight of the longsword also feels drastically different than normal.
From fighting that many Zombies and also sustaining injuries that reduced his hp to 230, he's clearly weakened as his body suffered too much damage. But without the Escape Ticket, he can't escape the place.
Aside from venting his bloodlust, he was also trying to see if he can find an Escape Ticket.
But even after killing almost every Zombie in this Swamp of the Underworld, he didn't get an Escape Ticket. At this point, there's only one way that he can end this and that is by defeating the Boss Zombie.
Since he already traveled through the entire swamp, he already knows where the Boss Zombie is.
