Zhang Ling 260

The terrain here was unusual. The tiger and dragon intertwined atop the mountains, while fire and water cooperated down below. Inside, there was a birth of two distinct spiritual veins, one of fire, another of water. The environment was mysteriously formed and naturally shaped into a formidable magic formation that balanced the elements of heaven, earth, water, and fire.

The coverage of this grand formation was extremely vast, at least tens of thousands of miles in every direction. Besides the mountain peak that could be seen from one's vantage point, it also included a valley spanning a million miles – a locale perfectly suited for human habitation.

This formation was mysterious, its power extraordinary. Once activated, it could borrow the force of heaven and earth for support. Even three or five Taiyi Golden Immortals couldn't breach its defenses easily.
