Mr. Knight, This Is the World of Immortality

When Don Quixote left La Manche, he was supposed to be in an inn, asking the innkeeper to make him a knight. But Rocinante stepped into the air and led him into a world of immortal cultivation where immortals wield swords and sects eat longevity. The flying sword is the unruly war horse, the fairy gate is the tower of the evil wizard, and the alchemy furnace is the stomach of the evil dragon... So, a crazy knight who was nearly fifty years old, wearing broken armor and riding a skinny horse, launched a challenge to the immortal high in the clouds. This lunatic misidentified everything in the world except who was eating people.
