My Years Guarding the Worlds of Yin and Yang

When my grandpa decided to pass his library down to me, the whole world of yin practitioners panicked.

I couldn't understand why. It was just a rundown library that barely made any money, so why did it cause such a commotion? My grandpa even lost his life, dying a horrific death.

Only later, when I became the owner of the library, did I understand.

The library has eighteen floors, each hiding its own secrets.

People warned me not to enter a haunted house, lest I lose my chance at reincarnation. But I was determined to sit high in the library and take charge of everything between the worlds of yin and yang.
