Modern cities are rife with hidden currents, and supernatural mysteries abound.
Shen Yan is a warm, cheerful paranormal investigator who specializes in solving supernatural cases. He has a unique ability: he can sense the spiritual power left behind by the dead and revisit their memories from life. The stronger the spiritual power, the more complete the memories he can recover.
A bizarre murder becomes the beginning of everything.
Through the spiritual power of the deceased, he glimpses an eerie vision: a blurry image that points to a mysterious bone tile that has never appeared in the world before.
Just then, the Spirit Catchers’ Bureau, the official agency responsible for supernatural affairs, comes calling. They have already found one of the fragments and reveal a shocking secret to Shen Yan: there are six bone-tile fragments hidden in the world. One is in their possession, while the other five are scattered across the globe, each concealing a secret powerful enough to overturn the balance between yin and yang.
To uncover the truth behind the case, Shen Yan joins forces with the Bureau and embarks on a perilous search for the fragments. Along the way, he encounters dangerous foreign realms, vicious vengeful spirits, and enemies lurking in the shadows. Every step is fraught with danger.
As the fragments are gradually brought together, Shen Yan begins to realize that this seemingly ordinary treasure hunt hides a deeper design.
Every supernatural case, every mysterious fragment, and every covert attempt on his life points to a shocking conspiracy spanning both the human world and the underworld.
And he himself is the most crucial, and most enigmatic, piece at the heart of this game.
With danger lurking in the fog, he must hold tight to every clue and pursue the truth to the very end. Only then can he tear through the darkness and glimpse the final truth.
