Why would there be such tall walls... it is because, in the past, the city was attacked by savages who massacred entire citizens – be they old or young. Some even said that the entire city was bathed in blood, which explains the red sands inside, as well as outside the city. So, the people who survived the catastrophe started to build tall walls with extremely heavy doors that only opened during the day and closed as soon as it was sunset.
A heavily guarded city. This is the Closed City. But, there is such a tragic story behind it, and how it became now is the product of the trauma that the catastrophe has left its people.
"You have a point." Meng Xing nodded in agreement. Not only the walls are impossible to climb to sneak in, but the inspection at the gate, too.
Jiang Yan looked at them. "The Closed City is near the borders of another kingdom, so we don't need to bother whether we will trespass on another kingdom or not." He spoke.
