"Wah..."
Looking at the fortress before them, Meng'er and the others could not help but gasp in amazement.
The fortress before them had been built atop a mountain. Generally speaking, this was not a good location for constructing a stronghold. Yet rather than a fortress, these ruins looked more like an observatory from the modern world. It had probably once been semicircular, resembling an opera house, but now only vast stretches of rubble remained. The only thing that could be said for it was that looking up at the sky from here gave one a relatively broad view.
