The metropolis once known as Demon City had now become a field of ruins sleeping at the bottom of the sea.
Looking out from the cockpit of the Golden Mad King, many landmark buildings could still be seen. The former River Mouth still had some faint traces, but no matter how magnificent the buildings once were, they had all become relics in the deep sea.
Perhaps soon, they would become the tombstone of a civilization.
As a coastal city, this place was submerged the moment the war broke out and sea levels rose.
But precisely because it was one of the first cities to be submerged, many of its internal structures became the best cover when facing the World Beast.
The Red Fortress Base was one of them.
According to the information Shen Feng had obtained, when the war between humans and the World Beast was at its most intense, many human forward bases, including the Red Fortress Base, were actually located underwater.
