Back from Adventure, I Open an Inn on a Dragon's Back

[Adventure | Cards | Management | Farming | A little bit of everything] Adventure isn't just about traveling far away. It's also about where you sleep at night. Wu Chen arrives in a fantasy world dotted with dungeons and ancient cards scattered across the land, and becomes a novice, first-tier spellcaster. He roams far and wide with adventurers, yet somehow always makes it back to his own place at night. Then one day, a succubus comes downstairs and respectfully asks to check out. That's when he discovers that his inn is built on the back of a world-spanning dragon, and he's the owner. If you can find it, you can stay. No money required, just your life. One night costs a year of your lifespan. Legendary slimes, high elves, and servants of the Old Gods come knocking one after another. The innkeeper seems unfathomably powerful to them, but in truth, he hasn't even learned more than a few spells. Even better, every time a guest checks out, Wu Chen can spend some of his lifespan to draw a card from them and take it into his next adventure. Sometimes, though, the news isn't good. Guests who stay too long leave behind a dream, hiding secrets they can't let go of. The innkeeper has to clean it up himself. As time goes on, Wu Chen travels farther and farther, and his hand fills with more and more cards. As for the inn, he's cultivated a vegetable garden that grows meat on the dragon's back, and the guests who stay there are getting stranger by the day... Wu Chen figures that as long as everyone pays their room fees on time, things should be fine.
