Kim Dokja gets the help of Lee Jihye and Lee Hyunsung's Mountain Smash to destroy all the green zones. He gets to a higher level and destroys the stairs so people can't get to them. He asks his group to give Going Pildu a potions to recover after certain periods of time. He drafts a contract for Gong Pildu's sponsor, a constellation who needs Gong Pildu in order for their story (and therefore their existence) to not fade away. It is something never been done before. The terms, which expire after 5 years, are that he gets to dole out absolute orders to Gong Pildu up to 10 times a day. This is under the condition of taking care of Gong Pildu and fostering him.
Kim Dokja finds out that Yoo Jongyuk is still in the hidden dungeon he entered. This leads him to realize he is in danger, as Yoo Jongyuk should've cleared it by now. This proceeds as you may expect, he rushes off with his team (plus Lee Jihye) and goes to the hidden dungeon. The dungeon, called the Theater Dungeon, is where you go into stories/movies and twist the stories to the Dungeon Master's satisfaction to clear them. Yoo Jongyuk had already cleared most of the stories, which were represented as posters. The first story they get into is dinosaur-themed. They hurry through the floors. Lee Jihye discovers that Kim Dokja had discovered potions at some point. He quickly says he was planning to share, even though he really didn't want to share. The potions are stat increases which can be used to help level up your stats, but only to a certain level. He proposes they do rock-paper-scissors to decide who gets a potion. He beats Lee Jihye every time, except a few where he purposefully let her win. IIRC, he was able to do this through predicting her movements with his Viewpoint skill.
Eventually, they reach the Dungeon Master's room. Yoo Jongyuk is being controlled by the Dungeon Master. Kim Donna utilizes a bunch of trump cards in this fight, while shouting stuff about Yoo Jongyuk's regression life (e.g. his child). To the constellations, the words are censored. In the end, he gets to the puppet master controlling Yoo Jongyuk, who uses a mental skill on Kim Dokja. Kim Dojka avoids it using Fourth Wall, and the Dungeon Master realizes something about him. We never get to know what. Yoo Jongyuk, now unconscious, is left in Lee Jihye's care. Kim Dokja gives her a note, telling her to give it to Yoo Jongyuk when he wakes up. He tells her not to look at it, but knows she will anyway. Lee Jihye misunderstands something based on the censored words shouted to the Theater Master, thinking they were secretly lovers and exclaims she will definitely give it to him.
They received a notice about the Main Scenario being cleared. The new scenario first requires each station to pick a representative.
Note: Yoo Jongyuk is called a sunfish sometimes in this portion of the arc, as they are strong but susceptible to mental degradation.
