Scully Special Prison Centre, the world’s most airtight prison. It was built with the aim of creating a prison from which ‘not even a bird can fly’. As far as I can remember, you were originally the design engineers for this prison, but when it was about to be completed, you were killed by someone and fell into a coma. When you regained consciousness, you were already in the cold door of the prison. The prison you built with your own hands has become a huge cage to imprison you, how to escape?
