简介：Baichengzi was the Tongwan City in those days. It was once the largest city in the world. Although it has been abandoned, the layout of the inner city and the outer city still exists. During this period, in addition to strengthening the outer city, Chuangying also defended the inner city. A lot of effort was put into it, in order to withdraw into the inner city and continue fighting once the outer city could no longer be defended.
