Iron Curtain City.
The first battlefront line of the human race, Jing Yue Country's Northern Territory's formidable pass. The city was devoid of women, children, the elderly, and the infirm. Other than armored soldiers, the remainder were all those cultivating.
As a fortress, Iron Curtain City was staggeringly vast, with considerable strategic depth.
The famous eighteen checkpoints within, each a hard nut to crack. Even as the Monster Tribe launched a massive invasion into the human states, the cultivators could rely on the precarious location of Iron Curtain City to hold for ten days to half a month.
Those ten days to half a month were significant. Jing Yue was no holy land of Great Xia Country, and most Mahayana cultivators gathered here hailed from the alliance nations of the Northern Region, while occasionally, a human powerhouse would come to hold the fort.
