Yan Dan had acquired this technique during his travels, which allowed him to summon the phantom of a Sword Immortal by burning his soul. This Sword Immortal, with a suave and dashing appearance, possessed unmatched combat prowess. It was Yan Dan's trump card, employed only in dire circumstances.

A White-robed Sword Immortal, it seemed, appeared amongst them, sword in left hand and a Wine Gourd in the right. With each step, he took a drink, recited a verse, and unleashed a sword strike.
"Do you not see the waters of the Yellow River coming from the sky, rushing into the sea and never returning?" With this strike, it was as if the Yellow River had descended; the sword light, like the surging river waters, swept the Four Great Demon Kings into its current.
