Jinwoo and his party appear to have cleared a low-level dungeon, when a hidden path to an unfamiliar temple is revealed. There they encounter a set of commandments and a group of monsters that cause them absolute despair.

Jinwoo joins a party led by Hwang Dongsuk to meet the headcount necessary for a C-Rank dungeon. Joined by another temporary hire, Yoo Jinho, the party defeats beasts without much trouble, but Jinwoo has suspicions about the group's lack of a healer.

As Jinwoo continues his training, he completes a daily quest one day by doing more than the quest requires, and a key that leads to a certain item appears in front of him.

At the D-Rank raid, Jinwoo is reunited with four of the Cartenon Temple survivors. Together, they explore the dungeon with Kang Taeshik and his men. After splitting up, they hear a scream, and then...

Out of the blue, a "job-change quest" pops up in Jinwoo's window. Feeling that it may help him get stronger, he enters the gate. Inside, he fights wave after wave of enemies, culminating in a knight who brings back memories of the Cartenon Temple.
