A murder caused by a book
The martial arts chaos caused by two books
A childhood promise will protect you for life.
When we were separated when we were young, when we got together when we grew up, you forgot me, but I remembered you, and you forgot your promise, but I still kept my promise. If you misunderstood me, I still protected you, just because we agreed to travel the world together.
The two male protagonists follow them through the world of the late Ming Dynasty.
Intention: meaning comes first
