When he woke up, Lu Xun and twelve strangers were trapped in a transit station that did not exist on the map. But the radio said: This car only carries twelve living people.
Twelve rules on the site determine who can be considered a "person". Once you lose the recognition of others, your name, identity and memory will gradually disappear and eventually become unclaimed luggage.
Lu Xun soon discovered that the hidden thirteenth rule could allow everyone's joint testimony to turn lies into facts. But when one name is created, another name is erased by reality.
What's even weirder is that he saw his death claim report in the lost and found office - the date of death was three days ago.
If they want to find a way out, they must first figure out: Who among the thirteen people should not have existed in the first place?
