Combining Cthulhu-style horror with the concept of "karma", it tells the story of high school student Ye Qing who goes deep into danger to save the mountain guard Uncle Qin who is imprisoned in a strange mirror world. Ye Qing possesses the "Broken Jade" and the "Blue Jade Dark Eye", which are not only the "keys" that can unlock power, but they themselves are also burdened with huge karmic entanglements.
What he faced was not only the terrifying abyss of twisted flesh and blood, and his possessed relatives, but also the cruel paradox that every time he used his power, he would accelerate the world towards a "bad disaster". When the JUNO laboratory intervened forcefully and dispatched a team of four dangerous "patients" codenamed "Orange, Yellow, Green, and Purple" who were both good and evil, the situation moved to the edge of even more uncontrollable madness.
Ye Qing must make a choice between redemption and destruction, sanity and madness. All actions require a heavy price, revealing the deep theme that knowledge is curse and salvation is destruction.
