I Turned a Sword Immortal into a Shut-In

On the day of the spring equinox, Chen Yuan, the owner of a little restaurant, found a beautiful sword immortal who had fallen from the sky. Faced with this cool, handsome sword immortal who was even teaching him how to cultivate, Chen Yuan hardly knew what to do. But just a few days later, he realized that her hobbies seemed a lot like his: she loved gaming and good food, and never left the house. She was a bona fide shut-in... This book is also known as The Daily Life of a Shut-In Sword Immortal, Why Bother Exorcising Demons When You Could Be Gaming, and My Favorite Streamer Turned Out to Be a Sword Immortal. P.S. This isn't just a slice-of-life novel. It has a main plot, which makes up about 30% of the story.
