Fago City? I Think It's Gotham City

On graduation day, I was sent to a city that didn't exist on the map. There are roommates who disappear, Bus Terminal No. 3, A tall black cat drinking milk, and a strange rule that "only the last name can be left behind." When the only one I trusted, Sister Ma, suddenly registered her full name as "Ma Yelian", the order in Fagao City began to get out of control. Immediately afterwards, the General Office investigated our organization overnight on the grounds of suspected biological experiments, and even determined that Black Cat was directed and performed by us. The agency was suspended, Sister Ma was taken away, but I was transferred to the fire station to be responsible for demolishing the dangerous building at No. 13 Ping An Road. But in that building, Zhou Ye's voice was heard: "Chen Mo, don't let them open the door."
