To cover her tuition, high school senior Su Mian takes an anonymous livestream job from a supernatural forum and gets caught up in the “Campus Ghost Face Incident.” As she livestreams her investigation of footage showing students collectively chewing on chalk, viewer donations can be exchanged for “rule fragments,” allowing her to see the black threads wrapped around NPCs’ necks.
As the livestream goes on, Su Mian discovers that the platform is actually a testing ground run by the “Rules Administration Bureau,” and that every supernatural tale is a warped reflection of real society: workplace manipulation becomes physical chains, school bullying gives birth to vengeful spirits, and even her own older brother turns out to be a former contestant who volunteered to become a vessel for the rules in order to save her.
When the Bureau’s director tries to bring about the collapse of the world to resurrect his daughter, Su Mian makes a startling decision: she gives viewers around the globe the choice between “sacrificing her brother to repair the rules” and saving him. The comments instantly fill with “Save her brother” and “Think of the greater good,” while she secretly launches a hidden program and begins livestreaming lessons on exploiting flaws in the rules to the entire world.
This isn’t an ordinary horror livestream. It’s the ultimate battle over human nature, rules, and technology. When Su Mian announces on camera, “The audience will vote on the next supernatural tale,” the pupils of the viewers below flash an eerie red... Do you dare press the vote button?
