ENTER THE INFERNO

Racing to find a cure for Xie Xue’s worsening condition, He Yu and Xie Qingcheng dive deeper into the mystery behind the forbidden drug RN-13—and with every new clue, the danger grows. Their investigation pulls them into a chilling trail of murdered professors, missing young women, and a crime so monstrous that those behind it will go to any length to keep it hidden.

But the threats don’t end there. Shadowy forces are also hunting He Yu himself, eager to exploit the terrifying power of the toxin still lingering in his body. And even though Xie Qingcheng stubbornly rejects the feelings He Yu has for him, he refuses to abandon him to face this nightmare alone.

As the truth burns ever closer, the bond between the two men is tested by fear, loyalty, and the secrets that have followed them since the beginning.
The tension, mystery, and emotional upheaval continue in Case File Compendium: Bing An Ben Vol. 5.
