The Humanity Exam

Chen Jing's mundane life shattered when his eccentric grandfather's dying wish led him to a freshly dug grave. Inside, an old DV camera played a chilling message: humanity was facing its final \"Biological Leap Exam.\" Before he could scoff, a pale, monstrous hand erupted from the screen, dragging him into a grotesque 1980s-esque parallel reality, a world reeking of blood and decay. A translucent system panel declared him \"Candidate No. 0,\" outlining the impossible: pass by killing an all-powerful examiner or destroying this entire dimension, or all human civilization would be completely erased. But a chilling \"invalid characters detected\" warning flashed: \"Don't believe them... this world is not what it seems.\" Trapped among smiling abominations and forced to play their twisted game, Chen Jing must uncover the cosmic truth before humanity receives its failing grade.
