An accident in a rainforest cave sends botanist An Qi into another world, where she inhabits the body of Ni Wen Ni, a graduate student in physics.
She is forced into a fateful entanglement with Ge Zhen, Ni Wen Ni’s brother by neither blood nor marriage, and dragged into an abyss of criminal underworld shadows and bloody old debts.
Two souls out of place: one devoted to goodness, the other leaning toward evil. Justice and crime collide violently in a single body.
The young man who swore to uphold the light breaks through the barriers between worlds and escapes the shackles of darkness.
In the endless cold night, he will take up his sword for the innocent and, in their darkest hour, kindle a faint light that pierces all darkness.
