Strange stories are coming from around the world, and the chosen ones are pulled into the terrifying dungeon and must abide by the rules to survive. Programmer Lin Yuan died suddenly while working overtime and traveled to this world. He discovered something that no one else knew - there was a line of crossed-out words below the rules. "The fifth rule is false. Those who follow it will die." Others are desperately following the rules, but he is desperately trying to see through them. But seeing the hidden rules comes at a cost: the moment you see it, it's also seeing you.
