Hades Tower

An abandoned teaching building with no exit, a group of cursed "night watchmen", and the class bell that rings at midnight every night - you can only get out of this building after attending nine classes alive. The protagonist Shen Yan, a former intern at the City Planning Bureau, was in a coma for seven days due to a bizarre car accident. When he woke up, he found that he was pulled into a teaching building that was always at midnight - the "Underworld Building". There is no exit in the building. Each floor is a "door to the underworld". Behind each door is an independent and terrifying replica world. Every seven days, all "Night Watchmen" will be forcibly pulled into the Gate of Hades, and must complete strange tasks before they can return to the building and continue to survive. Each copy has a set of seemingly normal "classroom rules" - "You are not allowed to leave your seat during class", "You are not allowed to look out the window", "You are not allowed to write on the blackboard" - breaking the rules will trigger death. Shen Yan relied on his spatial logic ability in urban planning and his sensitivity to architectural structures to survive the tests of life and death, and gradually discovered the truth...
