Wandering Around the World in the Era of Low Martial Arts

The morning sun shone lazily on the desk, and Lin Yu was staring at an old thread-bound book in a daze. The cover of the book was somewhat worn, and the pages were slightly yellowed. There was a vague ancient scroll painted on it, as if a mysterious world was hidden. Lin Yu is a history buff, especially obsessed with stories about the low martial arts era. He often fantasizes that he can travel to that era and experience it personally.
