A Chivalrous Suit

The hero travels to the end of the world with his sword, but he doesn't know his daughter's tender heart. In 911 AD, after the fall of the Tang Dynasty, the land of China fell into chaos and strife. A boy born with a confused life experience; a girl in yellow with love and hatred; a hero in troubled times, who can compete with him. This is an original fantasy world!
