At 3:01 in the morning, the knock on the door rang on time.
On the seventh night when programmer Lin Mo lived alone, there was no one on the surveillance screen, but an abnormal electromagnetic pulse signal source was detected at a distance of 0 meters. In the shot swallowed by snowflakes, a dazzling red color gradually condenses into a woman in a red dress, standing outside his door.
This is not an illusion or a prank. Lin Mo discovered that the knock on the door was related to the social APP "Spirit Realm" he participated in the development of three years ago - that program, which had been offline for a long time, unexpectedly opened a channel between the digital world and the world of the dead. The seven victims of the 1998 textile factory fire were trapped in a void with blurred data boundaries, making connection requests to the real world every three in the morning.
During the investigation, Lin Mo met Su Qing, the sister of the missing person Su Yu, but was systematically obstructed by technical director Chen Zhiyuan. As the pieces of the truth gradually come together, a more terrifying reality emerges: on the other side of the passage are not only the undead, but also the consciousness of living people imprisoned. Lin Mo himself has also been marked as part of the passage...
Purpose: The story explores the ethical dilemmas caused by the abuse of technology through a programmer who accidentally opens up a channel between the digital and the world of the dead. The core idea is: technology should not be a tool to evade guilt, historical debts must eventually be repaid, and the digital world is both a place of redemption and a place of punishment.
