The 45 Club were a group that surfaced after Miracle Day. As Miracle Day meant that people on Earth ceased to die, suicide became impossible, but some people became 'inventive', finding ways to get as close to death as possible. The 45 Club believed that jumping from forty-five floors up or higher was the only guaranteed way to lose consciousness forever. Zheng Yibao was one person who used this method. (TW: The Middle Men)
