King of the Underworld

I often wonder what yin and yang really are, and whether the world has two sides, yin and yang.

If what we can see is the yang side, what kind of horrors lurk in the unseen yin side?

“Because in this age of spiritual qi revival, the uncanny has emerged. In places beyond our sight, there is a group of people giving their lives to protect the countless lights of home across this world. Like a beam of light shining into the world's hidden side, they trade their lives for others, hoping to keep the world going.”

“Exorcising spirits and eradicating evil: it's my duty.”

“Who are you?”

“My name is Chen Ning. I'm a Judge, overseeing life and death in the mortal world and protecting peace for all eternity.”
