A scroll of silk book connects the two realms of Yin and Yang.
The Lin family has been a silk calligrapher for generations, specializing in writing yin contracts between living people, ghosts and gods.
One stroke determines life and death, one word pays for cause and effect.
Some people want to lose their yang life and call their deceased wives to sleep; some people want to use the yin contract to cover up an old murder case.
The putting of pen is a contract, with repercussions for both good and evil.
I write this contract, not to help evil spirits harm people, but only to save the souls of the dead in the world.
