Xia country bartender Yi Wan, due to his bar going bankrupt, mistakenly clicked an otherworldly recruitment link after getting drunk, accidentally time-traveling into the dark dungeon and becoming the owner of a dilapidated tavern. The dungeon's core rule states that if performance does not meet the standard within 30 days, he will be thrown into the samsara pool and reincarnated as a low-level monster. To return to his hometown, Yi Wan recruits goblins to renovate the tavern, learns mysterious wine recipes, ventures deep into the dungeon to collect raw materials, provides fine wine to various monsters, and exchanges them for gold coins, intelligence, and rare materials. As the tavern business thrives, he gradually unlocks new wine recipes and improves his strength, yet he also becomes entangled in dungeon disputes. In this perilous otherworldly realm, can Yi Wan pass the assessment and find the way home?
