Wielding the divine Sword of Fu Xi and bearing the title of Sword Immortal was merely the beginning of Lin Lie's legendary journey. When he fell into the lake and the Sword of Fu Xi shattered, the immortal dragon Shou-Lao from the ancient city of K'un Lun shared his dragon Chi with Lin Lie, making him the new Iron Fist.

But the young Iron Fist soon faced a daunting trial as the Timestream Entanglement pulled the isolated K'un Lun into an interdimensional conflict. The secret realm was in turmoil, and the gods were at war. Lin Lie had to steadfastly defend the sacred land of K'un Lun, keeping any threat that could tarnish the holy city at bay.
