Erin flees a Dragon and Goblins to an abandoned hilltop inn in a storm. She battles fear, explores the inn, finds a curtain to use as a dustrag, and thoroughly cleans the common room. Exhausted and hungry, she inadvertently triggers the world's system, obtaining the Innkeeper class at Level 1 with Basic Cleaning and Basic Cooking.

Forages and eats Amentus Fruit, discovers the seed pod’s toxicity, and uses it to repel a Rock Crab. She is then chased by a Goblin group, fortifies The Wandering Inn, and fights them inside using chairs and a seized knife, ultimately scaring them off with a shout. Exhausted and injured, she collapses and receives a system notification: Innkeeper Level 4.

Erin scavenges blue fruit, cleans the inn to a surprising degree, and ventures out dehydrated to locate water. She drinks from and bathes in a freezing stream, narrowly avoids being mauled by a huge predator fish, drags it back to the kitchen to process, and accidentally slices open her palm while butchering it. She endures excruciating pain into the night, distracting herself by reciting famous chess lines.

Erin woke up with her hand in extreme pain. While searching the kitchen for a way to remove her bandage, she discovered a magical cupboard with perfectly preserved food, but accidentally broke the magic. Later, she realized the skeleton from upstairs was missing, sending her into a state of paranoia. When a Goblin scout snuck in to ambush her, she overcame her fear, defeated it, and threw it out the front door.

Erin disposes of a rotting fish, discovers and is burned by acid flies, and cleans up at the stream. She rekindles the inn’s hearth using flint and steel, hauls water multiple times, and cooks pasta with dino-bird eggs and sausage while also making blue fruit juice. She flips the inn’s door sign to 'Open' and answers a knock, meeting a giant insectoid who asks to come in.

Erin encounters two guardsmen, a giant ant-person (Klbkch) and a lizard-man (Relc), at her inn. Initially terrified, she overcomes her fear and offers them food. She learns from them about the world's system of classes and levels, discusses her mysterious arrival, and has her badly infected hand miraculously healed by a potion Klbkch provides. At the end of the chapter, she levels up to [Innkeeper] Level 5 and gains the [Basic Crafting] skill.

Erin wakes with her hand fully healed and remembers gaining the [Basic Crafting] skill. She uses it to make a grass basket, then gets attacked by a dino-bird while gathering eggs. She later suffers severe food poisoning from the blue fruits and, by observing a group of Goblins, learns how to differentiate the safe fruits from the poisonous ones. After waiting all evening for Relc and Klbkch, she falls asleep and is awakened by a terrifying skeletal monster trying to break into the inn.

Erin knocks out an intruding mage with a pot, forces him to stop scamming, negotiates payment, and then feeds him despite their rough start. She discusses her mysterious teleportation, learns about Amentus Fruit poison, and sets clear terms for any future visits.

Erin wakes up to find Pisces at her door and reluctantly serves him breakfast. Her morning is further interrupted by the arrival of Relc and Klbkch. She inadvertently reveals Pisces's criminal past, leading to his arrest, and learns more about the world, including magic specializations, the city of Liscor, and the local guard system, before her guests depart abruptly to chase the escaped mage.

Worries about her empty pantry, is startled by Pisces, rejects his plea for sanctuary, threatens him with a knife, and is present when he is captured. Witnesses the fight between Pisces, Relc, and Klbkch that destroys her furniture. She is horrified when Relc tries to execute Pisces and intervenes by shouting and slamming a pot, demanding they stop the killing. Stands between Relc and Pisces, arguing vehemently against killing him. She withdraws her testimony to protect Pisces and then successfully argues that her inn is outside of Liscor's jurisdiction, forcing the guards to leave. She then kicks Pisces out.

Facing a food shortage and the poor state of her clothes, Erin resolves to travel to the nearby city of Liscor for supplies. During her journey, she is followed by Goblins, and upon arriving, she is overwhelmed by the city's non-human population and unfamiliar customs. After getting lost, she finds the Adventurer's Guild, where she has a friendly conversation with the receptionist Selys before being aggressively confronted and kicked out by a prejudiced Gnoll adventurer.
