Black Box: Test Subject No. 0122

The day his mother disappeared, she left behind only a note: "Live well. Don't come looking for me."

Along with the note were a diary filled with nightmares and a pass card black all over.

The diary said: In a white room, a black box hangs suspended. Something inside is watching her. There's a red door, and the thing behind it wants to get out.

To find her, Lin Xi lay down in the experimental pod of a future-tech facility, subject number 0122.

That day, the experiment went out of control. He was the only one recognized as a survivor. And from that day on, a voice took up residence in his mind. It called itself **Yuanxi**. It said it could help him find his mother, in exchange for his body.

The Hub Network has six domains, each ruled by a king. Seven people wear the seven deadly sins as their crowns, seeking to upload the consciousness of all humanity in the name of evolution.

And he is the indispensable "Origin" needed to unite the six domains.

Who is watching whom inside the black box? And what truth lies behind the red door?

When pure goodness becomes the only weapon capable of killing a god, Subject 0122 draws his blade.
